Consciousness has long intrigued thinkers, from ancient philosophers to contemporary neuroscientists. It is a complex phenomenon we encounter daily, yet we often find it difficult to fully define or comprehend.



This elusive aspect of our existence encompasses our thoughts, emotions, perceptions, and self-awareness. 



Despite significant advancements in fields like cognitive science and psychology, the true nature of consciousness remains one of humanity's <a href="https://www.earth.com/news/panpsychism-what-if-all-things-humans-plants-atoms-have-universal-consciousness/" target="_blank" rel="noreferrer noopener">most profound mysteries</a>.



Researchers are actively investigating how consciousness emerges from brain activity, the distinctions between conscious and unconscious states, and the broader implications of consciousness on our understanding of reality and existence.



<h2 class="wp-block-heading" id="h-hyperdimensional-paradigm">Hyperdimensional paradigm</h2>



Michael Pravica, a physics professor at the <a href="https://www.unr.edu/" target="_blank" rel="noreferrer noopener">University of Nevada</a>, offers a fresh perspective on the age-old mystery of consciousness. 



He proposes that understanding this <a href="https://www.earth.com/news/understanding-human-consciousness-through-eureka-moments/" target="_blank" rel="noreferrer noopener">complex phenomenon</a> may require us to look beyond our familiar dimensions.



Central to his theory is the concept of hyperdimensionality -- the intriguing possibility that our universe harbors more dimensions than the four we can perceive (three spatial dimensions and one of time).



Could this expanded view open new pathways for exploring the nature of consciousness? 



By examining these <a href="https://www.earth.com/news/where-in-the-brain-does-consciousness-reside-scientists-think-they-might-know/" target="_blank" rel="noreferrer noopener">broader dimensions</a>, we may uncover insights that have significant implications for our understanding of the universe and our place within it.



"The sheer fact we can conceive of higher dimensions than four within our mind, within our mathematics, is a gift... It's something that transcends biology," Pravica told Popular Mechanics. 



He believes that our ability to imagine and mathematically describe dimensions beyond <a href="https://www.earth.com/news/when-do-babies-start-gaining-their-consciousness/" target="_blank" rel="noreferrer noopener">our physical experience</a> hints at a deeper connection between consciousness and the fabric of the universe.



<h2 class="wp-block-heading" id="h-string-theory-and-higher-dimensions">String theory and higher dimensions</h2>



String theory is an ambitious framework in physics that seeks to unify all fundamental forces and particles into a <a href="https://www.earth.com/news/radical-new-theory-finally-unites-gravity-spacetime-and-the-quantum-realm/" target="_blank" rel="noreferrer noopener">single theoretical model</a>. It proposes that the basic building blocks of the universe aren't point-like particles but tiny, one-dimensional "strings" that vibrate at specific frequencies. 



These vibrations correspond to different particles, much like how different musical notes come from vibrations of a guitar string. To make the mathematics of string theory work, scientists have found that it requires additional spatial dimensions. 



These new dimensions extend beyond the three we experience daily. In some versions of the theory, there are up to ten or eleven dimensions in total.



The extra dimensions aren't easily observed because they might be compactified or curled up at scales so small they're beyond our current ability to detect. Imagine dimensions folded in on themselves like tiny loops at every point in space. 



<h2 class="wp-block-heading" id="h-dimension-of-consciousness">Dimension of consciousness</h2>



While the concepts of hyperdimensionality and string theory have received overwhelming acceptance from physicists, attributing a link between higher dimensions and consciousness can stir up a tempest in the <a href="https://www.earth.com/news/meditation-reveals-common-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">scientific teapot</a>.



Interestingly, Pravica, an Orthodox Christian with a PhD from <a href="https://www.harvard.edu" target="_blank" rel="noreferrer noopener">Harvard</a>, harnesses hyperdimensionality to bridge the gap between his scientific understanding and religious faith. He posits a fascinating theory: Jesus could be a hyperdimensional entity.



Pravica explained his perspective by citing a Biblical event. "According to the Bible, Jesus ascended into heaven 40 days after being on Earth. How do you ascend into heaven if you're a four-dimensional creature?" he pondered.



<h2 class="wp-block-heading" id="h-science-fiction-or-fact">Science fiction or fact?</h2>



Not everyone in the scientific field is convinced by Pravica's approach. Some argue that linking consciousness to hyperdimensionality -- and by extension, to religious concepts -- blurs the line between empirical science and personal belief. 



One scientist commented that such theories are bordering "on science fiction." <a href="https://www.fordham.edu/academics/departments/physics-and-engineering-physics/faculty-and-staff/stephen-holler/" target="_blank" rel="noreferrer noopener">Stephen Holler</a>, an associate professor of physics at <a href="https://www.fordham.edu" target="_blank" rel="noreferrer noopener">Fordham University</a> in New York, shares this skepticism. 



He emphasizes the importance of acknowledging gaps in our scientific knowledge without resorting to non-scientific explanations. 



"Gaps in scientific knowledge are attributed to divine intervention, rather than being seen as opportunities for further inquiry and understanding," Holler told Popular Mechanics.



He further expresses concern that this approach might <a href="https://www.earth.com/news/quantum-consciousness-and-you-what-happens-when-machines-become-sentient/" target="_blank" rel="noreferrer noopener">hinder scientific progress</a>. "It's a poor explanation mechanism that arguably stifles the inquisitive nature required for good science and teaches that it’s not okay to say, 'I don’t know'," Holler added. 



His viewpoint highlights the delicate balance between remaining open to new ideas and maintaining rigorous scientific standards.



<h2 class="wp-block-heading" id="h-dimension-of-consciousness-0">Dimension of consciousness</h2>



The debate sparked by Pravica's theory brings to light the broader conversation about how we explore consciousness. Could considering extra dimensions <a href="https://www.earth.com/news/mindfulness-can-lead-to-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">offer new insights</a>, or does it complicate the matter further? 



While hyperdimensionality is a well-established concept in theoretical physics, its application to consciousness is relatively uncharted territory.



This discussion also touches on how personal beliefs can influence scientific exploration. Throughout history, many scientists have drawn inspiration from their philosophical or religious views. 



The key challenge lies in ensuring that such influences encourage curiosity rather than limit it.



<h2 class="wp-block-heading" id="h-future-of-consciousness-research">Future of consciousness research</h2>



As we continue to investigate the nature of consciousness, it's essential to keep an open mind while adhering to scientific principles. 



Theories like Pravica's invite us to think creatively and consider possibilities beyond conventional wisdom. They remind us that much about the human mind -- and the universe -- remains unknown.



Advancements in technology, such as <a href="https://www.earth.com/news/quantum-connection-behind-brain-signals-and-human-consciousness/" target="_blank" rel="noreferrer noopener">quantum computing</a> and <a href="https://www.earth.com/news/ai-will-outsmart-humans-when-we-crack-the-neural-code/" target="_blank" rel="noreferrer noopener">artificial intelligence</a>, may soon provide new tools to study consciousness. 



These developments could help us understand how cognitive processes might interact with dimensions we have yet to explore fully.



The quest to comprehend consciousness is far from over. Ideas that challenge the status quo, like the hyperdimensional paradigm, play a crucial role in pushing the boundaries of knowledge. 



Whether or not such theories withstand scientific scrutiny, they provoke valuable discussions that drive progress.

Consciousness may stem from unseen dimensions beyond our reality

Consciousness has long intrigued thinkers, from ancient philosophers to contemporary neuroscientists. It is a complex phenomenon we encounter daily, yet we often find it difficult to fully define or comprehend. This elusive aspect of our existence encompasses our thoughts, emotions, perceptions, and self-awareness.

EPA: Climate Plan On Track Despite Mercury Ruling. A Supreme Court ruling that undermined a federal rule targeting mercury pollution will not affect the Obama administration's plan to limit greenhouse gas emissions to slow the effects of global warming, the head of the Environmental Protection Agency said Tuesday.
EPA Administrator Gina McCarthy said she was disappointed with last week's court ruling, but said comparing the mercury rule to the nearly finalized climate plan is "comparing apples and oranges."
The Supreme Court, in a 5-4 decision, ruled June 29 that the <a href="https://www.bing.com/search?q=epa&amp;cvid=f5b01ce4f79c4653a4f3bd6087db1d38&amp;FORM=ANAB01&amp;PC=HCTS">EPA</a> should have considered the costs and benefits of its plan before deciding to impose limits on mercury and other hazardous air pollutants.
McCarthy described the ruling as "very narrow" and said it posed little threat to the 2011 mercury rule and even less risk to the climate rule, a separate effort that sets unprecedented <a href="http://www.earth.com/news/ocean-carbon-dioxide-sink/">carbon dioxide</a> limits for coal-fired power plants that contribute to global warming.
A majority of U.S. power plants have already invested millions of dollars to install pollution controls needed to comply with the mercury rule, so the practical effect of the court's ruling will be limited, McCarthy said at a speech sponsored by the Christian Science Monitor.
The court decision did not set aside the mercury rule, but merely returned it to a lower court to decide how a cost-benefits analysis should be conducted, McCarthy said, adding that she is confident the rule eventually will be implemented.
"There's very compelling reasons for the utilities to continue to treat this as a requirement, and I think you'll see them doing that," she said.
Meanwhile, the Obama administration is on track to complete the so-called Clean Power Plan next month, McCarthy said. The plan is intended to cut earth-warming pollution from power plants by 30 percent by 2030, setting in motion one of the most significant U.S. actions ever to address global warming. Once completed, the rule will set the first national limits on carbon dioxide from existing power plants, the largest source of greenhouse gases in the U.S.
Congressional Republicans have vowed to block the rule and some GOP governors have said their states will not comply. McCarthy said she also expects a series of legal challenges to the rule, but said she is confident the administration will prevail.
"We're actually very good at writing rules and defending them in court, and this will be no exception," she said.
On a related topic, McCarthy slammed proposed spending cuts being pushed by Republicans in Congress, saying they could have significant impact on "the core functions of the agency."
The House is debating a bill this week that would slash the EPA's budget by 9 percent and block the agency from advancing a host of new rules, including the plan to reduce greenhouse gas emissions from existing power plants.
EPA officials receive calls daily from states and localities with questions about enforcement of environmental rules, McCarthy said, adding that the proposed budget cuts could make it difficult to answer those calls.
If the EPA can't answer those questions, who will? McCarthy asked. "Ghostbusters won't answer the phone," she said.

Pope Continues To Express His Environmental Protection Plan. Pope Francis challenged Latin America's youth to take up his environmental protection plan Tuesday, saying the defense of God's creation isn't just a recommendation but a requirement.
Francis appeal, delivered at Quito's Catholic University, is particularly relevant for Ecuador, a Pacific nation that is home to one of the world's most species-diverse ecosystems in the Galapagos Islands and <a href="https://www.bing.com/search?q=amazon+rainforest&amp;cvid=41008ed5a9c7456183c4c5be7f5e58f7&amp;FORM=ANAB01&amp;PC=HCTS">Amazon</a> rain forest, but is also an OPEC country heavily dependent on oil extraction. Pope Continues To Express His Environmental Protection Plan
Francis told students and professors that God gave humanity the Earth to not only cultivate, but to care for - a message he framed earlier this month in his headline-grabbing encyclical on the environment.
"It is no longer a mere recommendation, but rather a requirement because of the harm we have inflicted on it by our irresponsible use and abuse of the goods with which God has endowed it," he said.
He challenged universities to ensure that students' educations aren't aimed only at profitable careers but at helping the poor and the environment.
"There is a relationship between our life and that of mother <a href="http://www.earth.com/news/cyanobacteria-may-shed-new-light-on-the-history-of-life-on-earth/">Earth</a>, between the way we live and the gift we have received from God," he said.
Francis' environmental message has been cheered by indigenous groups, who have complained of being increasingly marginalized by Ecuadorean President Rafael Correa as he pushes mining and oil drilling in the Amazon. That push, coupled with high crude prices, allowed Correa to lift 1.3 million people out of poverty in his eight years in office.
Francis has called for environmentally responsible development, one that is aimed at helping the poor without sacrificing the planet.
It was a message he was likely to repeat later in the day at a meeting with indigenous groups, and then later this week in Bolivia, the next stop on his three-nation South American tour. Bolivian President Evo Morales has been hailed as an environmental hero to many for demanding rich nations do more to halt global warming, but he has been assailed by conservationists at home who say he puts oil and gas extraction ahead of clean water and forests.
Francis began his last full day in Ecuador with an open-air Mass that drew more than 1 million people and featured readings in Quichua, the native language mostly spoken in Ecuador, and Ecuadorean vestments for the pope.
In his homily, Francis urged Latin Americans to channel the same urgency that brought them independence from Spain two centuries ago into spreading the faith on a continent where Catholicism is losing souls to evangelical movements.
The Mass location, at Quito's Bicentennial Park, was appropriate given that Ecuador was where the first cries of independence against Spanish rule arose in Latin America in 1809.
"There was no shortage of conviction or strength in that cry for freedom which arose a little more than 200 years ago," Francis said. "But history tells us that it only made headway once personal differences were set aside."
He urged Latin Americans to channel that same purpose and unity into spreading the faith. Latin America counts 40 percent of the world's Catholics, but the church is losing out to Protestant evangelical ministries that have focused on the continent's poorest communities with real-life guidance on employment and education.
While the drop-off in Spanish-speaking South America hasn't been as sharp as it has been in Brazil, it is notable: Some 95 percent of Ecuador's population was Catholic in 1970, and now the figure is down to 79 percent, according to the Pew Research Center.
In a bid to counter the trend and return the Catholic Church to its evangelizing origins, Francis has called for the church to return to being a missionary church that looks out particularly for society's poorest and most marginalized. It's a message he crafted for the entire Latin American church when he played a leading role in a 2007 conference of bishops in Aparecida, Brazil.
"Evangelization doesn't consist in proselytizing, but in attracting by our witness to those who are far off, in humbly drawing near to those who feel distant from God and the church, those who are fearful or indifferent," Francis told the crowd. "Proselytism is a caricature of evangelization."
Francis arrived at Bicentennial Park to cheers of people who camped out overnight for a good spot. They were rewarded with a pre-dawn deluge that sent some 20 people to paramedics with hypothermia, said city operations director Cristian Rivera. But the sun broke out as Francis arrived in his popemobile, with fans tossing confetti on him as he zoomed by.
"The joy at seeing the pope gives us the warmth we need," said Abel Gualoto, a 59-year-old seafood vendor as he rubbed his cold hands together to try to stay warm.
Tuesday was expected to end with a visit to the Church of the Society of Jesus, known locally as Iglesia de la Compania. The Jesuit church, a gem of Spanish Baroque, is one of the oldest and most well-known in Ecuador. It houses a painting of the Virgin Mary that was said to shed tears in 1906.

Republicans Want To Tap Into Wildfire Disaster Reserves. House <a href="https://www.bing.com/search?q=republicans&amp;cvid=e9dda83c7e2f47a58dc75582969613a6&amp;FORM=ANAB01&amp;PC=HCTS">Republicans</a> are proposing that some wildfires be treated like federal disasters, an attempt to win broader support for legislation that targets overgrown national forest lands.
The legislation focuses on speeding up timber harvests and the removal of underbrush the Forest Service deems necessary to improving the health of a forest. Some Democratic lawmakers and environmental groups have been critical of the bill because they say it would erode key environmental safeguards.
With a House vote expected this week, GOP lawmakers are adding the federal disaster language to the bill, something the<a href="http://www.earth.com/news/coal-plants-closed-trump/"> Obama</a> administration first proposed early last year, but with some wrinkles.
Under current policy, the agencies fighting wildfires divert money toward firefighting from other programs during particularly busy years. But that practice delays the very efforts designed to prevent fires in the first place, such as the thinning of dead trees and the removal of thick underbrush. Supporters say that letting federal agencies tap into a disaster fund will prevent such borrowing and lessen the risk of catastrophic forest fires in the coming years.
This year's fire season appears to be shaping up a busy one, adding some urgency to tackling the funding problem. A report Monday from the National Interagency Fire Center showed 51 active large fires across 10 states, with more than half taking place in Alaska and Washington.
"My colleagues on both sides of the aisle agree that current efforts to combat the growing threat of catastrophic wildfires are failing our communities. This package charts a new course," said Rep. Rob Bishop, R-Utah., the chairman of the House Natural Resources Committee.
Bishop said the bill should garner broad support. But Robert Bonnie, who oversees natural resource issues at the Agriculture Department, which houses the Forest Service, indicated the GOP has more work to do to win over the administration. He described the bill as a step forward but said the changes don't go far enough to address financial challenges that the Forest Service faces as more and more of its budget is eaten up by fighting forest fires. Bonnie said he wanted to continue talking to lawmakers before formally taking a stand.
One of the biggest differences between what House Republicans are backing and what the administration proposed is when federal agencies could tap into a disaster account.
The government estimates its firefighting needs based on the average costs of the 10 previous years. The administration supports funding the agencies at 70 percent of the 10-year average and using the Federal Emergency Management Agency's disaster fund to cover remaining costs as well as provide more money to treat forests.
Bonnie said fires such as the "Rim Fire" in California two years ago should be treated as federal disasters regardless of when they occur. That fire scorched 400 square miles and cost $125 million to fight.
"You can give the Forest Service new authority, but unless you solve the budget problem, the Forest Service lacks the resources to increase the pace and scale of forest restoration," Bonnie said.
House Republicans would let the agencies tap into a disaster fund only after they've exhausted that year's firefighting budget, and the extra money could only be used for putting out fires. The money would also be part of a separate account within FEMA so that it wouldn't take money from recovery efforts for hurricanes, tornadoes and other natural disasters.
And while the administration wants to put more money into treating forests before fires occur, the House bill is focused on lowering regulatory hurdles to speed timbering projects. Also, House Republicans want to require that groups suing the federal government over a thinning project buy an insurance bond in the event they lose. That way, the federal government could recoup the expense of defending itself in court. Rep. Jared Polis, D-Colo., said the provision will be a "poison pill" for many Democratic lawmakers.
Bonnie cited the bonding requirement as one of the most troubling provisions in the bill. Still, he sought to maintain an environment where the two sides could potentially iron out some of their differences.
"We want to work with them," Bonnie said. "The current design of those provisions we think can be a lot better."

Republicans Want To Tap Into Wildfire Disaster Reserves

Under the scorching sun, dozens of Thai villagers, dressed in flowery shirts and traditional costumes, parade a white cat caged in a bamboo-woven basket door-to-door and let neighbors splash water on the unlucky feline, while chanting an ancient tune: "Rain, rain, come pouring down. We barely had any this year. Without rain, our rice will die."
It's a desperate plea to the god of rain, in the belief it will hear the cat's cry and answer the farmers' prayers.
Thailand's rainy season officially began in the last week of May, but it rained only once in the Ban Lueam district in northeastern Nakhon Ratchasima province. It is one of more than 250 districts - or nearly 20 percent of the country - that have been declared emergency disaster zones as the prolonged drought becomes the worst in decades, its impact felt most acutely by farmers growing Thailand's most important agricultural export: rice.
At the beginning of July, the amount of usable water in major dams across the country - except in the west - dropped to below 10 percent, according to the Irrigation Department. The water level at Bhumibol Dam has dropped to its lowest point in 51 years.
In the capital, Bangkok, the Metropolitan Waterworks Authority has been slowing down tap water production since May. The head of the authority, Gov. Thanasak Watanathana, told The Associated Press that without rains, the current water supply for daily consumption in Bangkok and its nearby provinces will last only 30 days. However, he said forecasters are expecting rains next month.
For rice farmers, it may already be too late.
The drought and the critical water shortage in dams have prompted the Agriculture Ministry to ask farmers to hold off on planting their crops. The Office of Agricultural Economics estimated that the delay could cost farmers in Thailand's central plains alone 60 billion baht ($1.8 billion) in potential losses.
"Every year in the past, in June and July, in every part of the country - the north, the central or the northeast - farmers would have started planting their rice," said Sompong Inthong, the permanent secretary at the Agriculture Ministry. "The real damage will be with those who have already planted but there's not enough water. We have to look at how we can help them."
The Royal Rainmaking and Agricultural Aviation Department have sent a fleet of propeller aircrafts on more than 3,000 flights since March to increase precipitation by cloud seeding, an artificial rainmaking technique spearheaded by King Bhumibol Adulyadej. Despite the high rate of success, it did little to fill the dams.
Together with Vietnam, Thailand is one of the world's top rice exporters. But because of the drought, the Office of Agricultural Economics estimates this year's main crop will decrease by 11 percent, or about 24 million tons from the average of 27 million tons per year.
The Thai Rice Exporters Association says at least 3 million tons of off-season rice has disappeared from the stock since the beginning of the year due to the drought. The main concern, however, is the main farming cycle, which begins in May and is harvested as early as October.
"If the main crop's produce is damaged, even 10 or 20 percent, it means the amount of rice will drop drastically," said Chookiat Ophaswongse, the association's honorary president. "If there's still little rain from now, I'm afraid it will make quite an impact on next year's export figures."
He said that Thailand's competitiveness against rival exporters, such as Vietnam, "which have less impact from the drought than Thailand, will be affected."
Meteorologists from the U.S. National Oceanic and Atmospheric Administration and NASA say 2014 was the hottest year on record since 1880, when Earth's average surface temperature has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) - a trend that is largely driven by the increase in carbon dioxide and other human emissions into the planet's atmosphere. The majority of that warming has occurred in the past three decades.
The reason involves El Nino, a warming of the tropical Pacific Ocean that affects weather worldwide. This year, NOAA says, El Nino has an 85 percent chance of lasting through winter 2015-2016.
In Ban Lueam, a drought-plagued rural district 340 kilometers (211 miles) northeast of Bangkok, several hundred farmers did not have any choices but to start growing their rice and hope for the rain.
Last week, Boonchan Thasunthorn, 58, finished plowing nearly 16 acres (6 1/2 hectares) of his rice farms by using a crumbling 16-year-old manual tractor. He said he would rather take risk by sowing the crops in the absence of rain than holding off until it was too late.
Boonchan's village is outside the irrigation zone and the only access to natural water is the Chi River, which has nearly dried up.
"I'm just waiting for it to rain. ... If the drought continues, it's going to be tough for me. But I can't just sit here and do nothing, or else I'll starve," he said, adding that he still owed 100,000 baht ($2,950) to the Bank of Agriculture for the equipment and maintenance costs for his farms.
"This drought has hit me the hardest, but I don't know what else to do. Once you're a farmer, it's hard to be something else."

Thai Farmers Beg The Spirits For Rain To End Crippling Drought

Under the scorching sun, dozens of Thai villagers, dressed in...

The Obama administration moved Wednesday to significantly expand a requirement for utilities to install inexpensive safety valves on gas lines across the U.S. after deadly fires and explosions going back decades that could have been avoided.
The Transportation Department proposal would cover new or replaced natural gas lines serving multi-family dwellings, small businesses and homes not already covered under a 2009 mandate.
The National Transportation Safety Board and other safety advocates have pressed for years to broaden requirements for so-called excess flow valves. The devices cost about $30 apiece for residential use, according to officials, and are designed to automatically shut off the flow of gas when a line is ruptured.
An Associated Press investigation in 2012 uncovered more than 270 accidents dating to 1968 that could have been averted or made less dangerous if the valves had been in place.
Fire Capt. David Wells led the first company responding to the scene of a gas explosion in Springfield, Massachusetts, in November 2012 that injured at least 20 people and damaged dozens of buildings with a boom heard for miles. Investigators said the accident could have been averted if valves had shut off the spewing gas.
Having the valves in place also would help keep first responders safe, said Wells, adding that some of his colleagues are still recovering from injuries.
"It caused three guys to retire from the job, and some guys are still suffering from headaches and pains. Some of the guys are more gun-shy now when it comes to gas leaks," Wells said.
Officials stressed that the valves won't prevent lines from being ruptured, such as when a backhoe doing excavation work slices through a gas pipe servicing a house. But by limiting the amount of gas that escapes, the valves can prevent a buildup of fuel that can contribute to explosions or fires.
"This important action will add extra protections to communities serviced by the nation's largest network of pipelines," Transportation Secretary Anthony Foxx said in a statement.
Federal officials say the valves could have averted at least eight accidents that killed 10 people since 1998, including Springfield.
The valves also could help reduce emissions of greenhouse gases that are contributing to climate change, officials said.
As utilities across the country dig up their old cast-iron and plastic gas lines over the coming years, the proposed rule would ensure they are replaced with safer lines that can be shut off more easily, said Carl Weimer, executive director of the Pipeline Safety Trust, a safety advocacy group.
But Weimer said the proposal "won't do much good for existing lines that lack valves and aren't being replaced."
Customers could request the safety valves under the rule for the tens of millions of gas lines already installed across the U.S., but it does not specify who would pay for their installation.
About 180,000 automatic valves would be installed annually under the rule, according to the Transportation Department's Pipeline and Hazardous Materials Safety Administration.
Manual valves would be required for new or replaced gas service lines that deliver higher volumes of gas, such as for apartment buildings and large commercial or residential gas customers. The government projected more than 40,000 of those valves would be installed annually.
Out of more than 67 million gas service lines in the U.S., just over 9.3 million currently have excess flow valves, according to information submitted to regulators. A breakdown by type of customer was not available.
The American Gas Association said its members have been voluntarily installing the valves on some lines for the past two years.
The NTSB was reviewing the proposal to determine if it satisfies the board's prior recommendations to install excess flow valves on all new and renewed gas lines, regardless of the type of customer, spokesman Keith Holloway said.
Industry representatives previously have raised concerns about the potential cost of installation, particularly for larger gas lines that would require specialized valves. American Public Gas Association Vice President John Erickson said utilities would be more accepting of a rule that is limited to smaller lines.
But Erickson added that quality control during valve manufacturing was crucial to make sure the devices don't inadvertently shut off the flow of gas for no reason.
"It's not going to affect every type of accident, but one where an excavator hits a service line, they seem to be effective at reducing the (gas) flow to where it's an insignificant risk," he said.
Installing the valves on new and replaced lines should cost between $4.4 million and $20.3 million per year, depending on the price of the valves, the Transportation Department said. Benefits from damages avoided were generally lower - between $7.3 million and $14 million.
Transportation officials said the proposal was nevertheless justified because of hard-to-measure benefits, such as avoided evacuations, environmental damages and the possibility of a high-consequence incident that could inflict mass casualties.
The 2009 mandate required excess flow valves to be installed on new and replaced gas distribution lines serving single-family residences. The proposal would expand that to include lines serving multiple homes, duplexes and small multi-family buildings, and shops ranging from doctors' offices and shopping centers to banks.

House Republicans Take On Obama's Environmental Agenda. Republicans Wednesday repelled numerous attempts by Democrats to defend the Obama administration's environmental agenda as the GOP-controlled House debates a $30 billion measure funding the Environmental Protection Agency and the Interior Department for the upcoming budget year.
Democrats came out on the losing end of votes on administration rules on selling items containing ivory from endangered African elephants, curbing runoff from mountaintop removal coal-mining operations, hydraulic fracturing on federal lands and potential protections for the sage-grouse and the grey wolf.
The White House has vowed to veto the bill over GOP "riders" - or policy add-ons - to thwart Obama's moves on the environment and funding cuts for the <a href="http://www.earth.com/video/gentoo-penguins-are-not-one-species-but-four/">EPA</a> budget and other programs. House Republicans Take On <a href="https://www.bing.com/search?q=obama&amp;cvid=30887235709d49ebb95323c914a5d200&amp;FORM=ANAB01&amp;PC=HCTS">Obama'</a>s Environmental Agenda
Republicans have tried many of the riders before only to see them stripped out in end-stage negotiations but they hold a stronger hand now that they control the Senate.
Republicans are seeking to delay the administration from cracking down on ivory sales after widespread complaints from owners of musical instruments, antiques and guns made with ivory, who say the rules are making it more difficult to trade in such items and reducing their value. A revised rule is expected this month in response to the protests.
The rules are aimed at combating elephant and rhinoceros poaching. An amendment by Raul Grijalva, D-Ariz., to block Republicans from interfering with the ivory rule was rejected by a 244-183 vote.
Grijalva also lost an attempt to defend upcoming Interior Department rules on runoff from mountaintop mining operations, which he said have filled in 2,000 miles of streams, destroying habitat and killing fish. Republicans say the department isn't taking job losses from the struggling coal industry into account.
Republicans also defended provisions that try to block proposed the Bureau of Land Management from enforcing new rules governing the use of hydraulic fracturing to extract oil and natural gas from BLM lands. Republicans said the rules create a duplicative compliance system in states that have already issued their own rules and would drive down production, but Rep. Betty McCollum, D-Minn., countered that the BLM is already working with states to iron out kinks.
The underlying bill is expected to pass the House on Thursday by a nearly party-line vote. Companion Senate Appropriations Committee legislation is also controversial but has yet to be brought up for debate by the full Senate.

Heat And Drought Creating Lethal Conditions For Salmon And Trout. Drought and record hot weather are producing lethal conditions for salmon and trout in rivers across the West.
A recent survey released Wednesday of the lower reaches of 54 rivers in <a href="https://www.bing.com/search?q=oregon&amp;cvid=d53646563b654669bae584293d369563&amp;FORM=ANAB01&amp;PC=HCTS">Oregon</a>, California and Washington by the conservation group Wild Fish Conservancy showed nearly three-quarters had temperatures higher than 70 degrees, considered potentially deadly for salmon and trout.
Low river flows from the record low winter snowpack, which normally feeds rivers through the summer, combined with record hot weather have created a "perfect storm" of bad conditions for salmon and trout, said U.S. Fish and Wildlife Service supervisory fisheries biologist Rich Johnson. Heat And Drought Creating Lethal Conditions For Salmon And Trout
"It's unprecedented, I'd say," Johnson said.
Oregon Climate Center Associate Director Kathie Dello says the entire West Coast saw record low snowpack last winter, leading to low rivers this summer. All three states had record high temperatures for June, with Oregon breaking the record by 3 degrees, and the three-month outlook from the National Oceanic and Atmospheric Administration is for continued warmer and drier-than-normal weather made worse by the ocean-warming condition known as El Nino, she added.
"This is the worst case scenario playing out right now, a warm winter and then a warm and dry summer," she said.
The Willamette River saw scores of dead salmon in June.
This week, state biologists examined about 50 dead sockeye salmon in the mouth of the Deschutes River. State fisheries biologist Rod French said they appeared to have been infected with a gill rot disease associated with warm water, and had probably left the warm waters of the Columbia River in search of cooler water.
In California, inland fisheries manager Roger Bloom says they are considering emergency fishing closures on several rivers so that fish weakened by the warm water do not die from being played by an angler, even if they are released. They include the lower Merced, the American and the Klamath.
In Washington, two federal fish hatcheries in the Columbia Gorge released 6 million juvenile salmon two weeks early in the Columbia River, in hopes they would have a better chance of reaching the ocean before temperatures got even warmer, said Johnson.
"It's just a perfect storm of bad weather conditions for salmon," he said. "Pray for rain and snow."
River flows are so low, the Washington Department of <a href="http://www.earth.com/news/fish-fossils-provide-new-insight-into-the-origins-of-teeth/">Fish</a> and Wildlife is sending out crews to clear out impromptu dams people build with rocks to create a pool to cool off in, so the salmon can swim upstream to spawn, said department drought coordinator Teresa Scott. Rivers are at levels normally not expected until September, and no one knows if they will drop even further.
"This is such a huge magnitude compared to previous droughts," she said. "Records available from before don't come close to preparing us for what we are encountering this year."
In Oregon, deputy fisheries chief Bruce McIntosh says they have imposed closures around cool water areas where salmon seek refuge at the mouths of tributaries flowing into the lower Umpqua River, but he did do not anticipate any more closures unless things get worse.
"Certainly we've had significant droughts in the past, such as the late 70's," he said. "But the challenge this year has been not only are there drought conditions, we're having August temperatures in June. That combination we really have not seen before."
Liz Hamilton of the Northwest Sportfishing Association, said closures are not needed, because when temperatures get too warm, fish go off the bite, and anglers quit fishing anyway.
"It as 2001 or 2002 and the Columbia got really hot in the fall," she recalled. "There were fish everywhere. You had a better chance of one jumping in the boat than of biting. It's one of those things about fishing. If people are not catching, they are not spreading the word to go, and less and less people go."

Heavy June rains causing heavy nutrient runoff into lake basin

NOAA and its research partners, using an ensemble modeling approach, predict that the 2015 western Lake Erie harmful algal bloom season will be among the most severe in recent years and could become the second most severe behind the record-setting 2011 bloom.

The effects of the cyanobacterial blooms include a higher cost for cities and local governments to treat their drinking water, as well as risk to swimmers in high concentration areas, and a nuisance to boaters when blooms form. These effects will vary in locations and severity with winds, and will peak in September.

The bloom will be expected to measure 8.7 on the severity index with a range from 8.1 to potentially as high as 9.5. This is more severe than the last year's 6.5, and may equal or exceed 2013, which had the second worse bloom in this century. The severity index runs from a high of 10, which corresponds to the 2011 bloom, the worst ever observed, to zero. A severity above 5.0 indicates blooms of particular concern.

"While we are forecasting a severe bloom, much of the lake will be fine most of the time. The bloom will develop from west to east in the Lake Erie Western Basin, beginning this month. It is important to note that these effects will vary with winds, and will peak in September," said Richard Stumpf, Ph.D., NOAA's ecological forecasting applied research lead at NCCOS, who formally presented the forecast in a media event and science presentation at Ohio State University's Stone Lab on Lake Erie today.

"This is the fourth seasonal harmful algal bloom outlook for Lake Erie that NOAA has issued," said Holly Bamford, Ph.D., assistant NOAA administrator for the National Ocean Service performing duties of the assistant secretary of commerce for conservation and management. "NOAA's ecological forecasting initiative, including this Lake Erie seasonal forecast, the NOAA weekly HAB bulletin, and the experimental early season HABs Tracker, provide science-based information that water managers, public health officials, and others need to make critical decisions to protect the health of their communities, understand environmental impacts, and mitigate damages to recreational activities that are a vital part of the region's economy."

The 2015 seasonal forecast uses models that translate spring nutrient loading into predicted algal blooms in the western basin of Lake Erie. After a relatively dry April and May, the heavy rains in June produced record discharge and nutrient loadings from the Maumee River, which runs through Toledo, Ohio as well as northeastern Indiana, will result in a more severe bloom. This marks the fourth year that NOAA has issued an annual outlook for western Lake Erie.

Models were developed by scientists at NOAA's National Centers for Coastal Ocean Science (NCCOS), the University of Michigan, LimnoTech, the University of Michigan Cooperative Institute for Limnology and Ecosystems Research, and the NOAA Great Lakes Environmental Research Laboratory (GLERL). The models use nutrient load data collected by Heidelberg University's National Center for Water Quality Research.

"Last summer's Toledo water crisis was a wake-up call to the serious nature of harmful algal blooms in America's waters," said Jeff Reutter, Ph.D., senior advisor to, and former director of, The Ohio State University's Sea Grant program and Stone Laboratory. "This forecast once again focuses attention on this issue, and the urgent need to take action to address the problems caused by excessive amounts of nutrients from fertilizer, manure and sewage flowing into our lakes and streams."

To provide more real-time information during the bloom season, NOAA has produced HAB bulletins for western Lake Erie since 2008. The bulletins will continue at the twice-weekly frequency established during last season's Toledo event, and can be received by a subscription to the NOAA Lake Erie HAB Bulletin. Additional information on the size and movement of the bloom can be found via NOAA's experimental HAB Tracker. As the summer progresses, field observations on water quality, algal biomass and toxicity will be collected by NOAA GLERL and CILER, the Ohio State University's Sea Grant Program and Stone Laboratory, Heidelberg University, the University of Toledo, Ohio EPA, and LimnoTech. USGS will work with NASA in providing satellite tracking of the bloom as well. These results will provide valuable information to regional managers and assist NCCOS scientists in further refining the accuracy of this year's forecast models.

The Lake Erie forecast is part of a NOAA ecological forecasting initiative that aims to deliver accurate, relevant, timely and reliable ecological forecasts directly to coastal resource managers and the public as part of its stewardship and scientific mandates for coastal, marine and Great Lakes resources. Additionally, NOAA currently provides, or is developing, HABs and hypoxia forecasts for the Gulf of Maine, Chesapeake Bay, the Gulf of Mexico and the Pacific Northwest

NOAA, NASA, EPA, and the U.S. Geological Survey announced, in April, a $3.6 million multi-agency research effort designed to be an early warning system for freshwater nuisance and toxic algal blooms by using satellites that can gather color data from freshwater bodies during scans of the Earth. The project will improve the understanding of the environmental causes and health effects of cyanobacteria and phytoplankton blooms. The effort includes the Great Lakes and will further strengthen initiatives like the NOAA Lake Erie HABs forecast.

Severe Algal Bloom Predicted For Lake Erie

In the most comprehensive analysis of the impact of climate change on critical pollinators, researchers have found that rapid declines in bumblebee species across North America and Europe are strongly linked to climate change. The study was published in <a href="http://www.sciencemag.org/lookup/doi/10.1126/science.aaa7031" target="_blank" rel="noopener">Science</a>.

“Pollinators are vital for food security and our economy, and widespread losses due to climate change will diminish both,” states Jeremy Kerr, lead researcher and professor at the University of Ottawa’s Department of Biology. “We need to figure out how we can improve the outlook for pollinators on continental scales. But the most important thing we can do is begin to take serious action to reduce the rate of climate change.”

Although previous smaller-scale studies on other species have shown that species expand to the North Pole as the climate warms, these new findings show that bumblebee species are not relocating. Instead, they’re losing range from the south, disappearing over huge areas with the rapid warming on continental scales.

This is the first cross-continental analysis to study how a large group of pollinators responds to climate change. The study has also discovered a new biological mechanism that explains how species may respond to climate change based on their evolutionary past.

“We’ve lost about 300 km from the ranges of bumblebees in southern Europe and North America. The scale and pace of these losses are unprecedented. We need new strategies to help these species cope with the effects of human-caused climate change, perhaps assisting them to shift into northern areas," urges Professor Kerr.

The study used long-term observations collected over a period of 110 years across Europe and North America, with a database of approximately 423,000 geo-referenced observations for 67 bumblebee species. The observations tested for latitudinal and thermal limits and movements along elevation gradients.

Haze From Canadian Wildfires Spreads Across The US. Haze From Canadian Wildfires Spreads Across The US. Hazy conditions across the West are in part due to large Canadian wildfires, blazes fueled by the same hot, dry conditions that have sparked fires in the United States.
The smoke has caused spectacular red sunsets in places like Seattle and prompted air quality warnings in many states.
---
FIERY CANADA
Blazes are burning in parts of British Columbia, Alberta and Saskatchewan. In Saskatchewan, more than 10,000 people have been forced from their homes and the Canadian Interagency Forest Fire Centre, which coordinates firefighting services for the provinces and territories, said Canada may have to seek more help from the U.S. and abroad.
Alberta said Wednesday it was bringing in 62 firefighters from Mexico to help battle 92 wildfires burning in the province, including 33 listed as out of control.
British Columbia, with more than 180 fires, was bringing in crews from Australia.
---
SMOKE SOUTH OF THE BORDER
Haze from smoke drifting south from the wildfires lingered over parts of eastern Colorado for the third straight day on Wednesday, prompting a health warning for Denver and the heavily populated region north and south of the city. The haze combined with clouds gave Denver an unusually gloomy look in the middle of summer and blocked the view of the mountains.
The tiny particles of wildfire debris in the air pose a health risk for people with lung disease, older adults and children and anyone who exerts themselves working out outdoors, said Christopher Dann of Colorado's air pollution control division. While expected rain could clear out the haze, Dann said Colorado - which remains free of large wildfires after a wet spring - could be again dealing with smoke from the Canadian fires over the coming days and weeks.
Joanne Todd of the Puget Sound Clean Air Agency said smoke from wildfires in British Columbia has crossed into Washington state, but is sitting high in the atmosphere and has little impact on the health of residents.
"It's not affecting us at ground level," Todd said. "The smoke is pretty high in the atmosphere."
She said that could change in the future.
Air quality advisories have also been issued in places like North and South Dakota.
Canadians, obviously, are being affected as well. Environment Canada continued to issue special air quality advisories for parts of British Columbia, Saskatchewan, Manitoba and northwest Ontario due to wildfire smoke. Haze From Canadian Wildfires Spreads Across The US

HOT AND DRY
The Western provinces have seen very hot, dry and windy conditions.
Kerry Anderson, a research scientist with the Canadian Forest Service, said the weather pattern known as El Nino, which is caused by the warming of the Pacific Ocean off the coast of South America, is responsible.
He expects weather conditions will settle down in Saskatchewan in the coming weeks, but warmer than normal temperatures will likely persist for a while in B.C. and Alberta.
Anderson said even if crews bring the Saskatchewan fires under control, they may not actually be put out until the fall.
Similar conditions across the American West have helped fuel for large, destructive blazes, including one in Wenatchee, Washington, that began in late June that destroyed nearly 30 homes.

NASA: Oceans Slowed Global Temperature Rise. A new NASA study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global temperature rise observed during the past decade.

Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA's Jet Propulsion Laboratory, Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized. They also found the movement of warm water has affected surface temperatures. The results were published Thursday in the journal Science.

During the 20th century, as greenhouse gas concentrations increased and trapped more heat energy on Earth, global surface temperatures also increased. However, in the 21st century, this pattern seemed to change temporarily.

"Greenhouse gases continued to trap extra heat, but for about 10 years starting in the early 2000s, global average surface temperature stopped climbing and even cooled a bit," said Willis.

In the study, researchers analyzed direct ocean temperature measurements, including observations from a global network of about 3,500 ocean temperature probes known as the <a href="http://www.argo.ucsd.edu/About_Argo.html">Argo array</a> . These measurements show temperatures below the surface have been increasing.

[caption id="attachment_2382849" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/07/ocean-temperature-trend_1big_graphic_nasa.jpg"><img class="size-thumbnail wp-image-2382849" src="http://cff1.greenatom.net/uploads/2015/07/ocean-temperature-trend_1big_graphic_nasa-150x150.jpg" alt="Maps of temperature trends at four layers in the global ocean" width="150" height="150" /></a> Maps of temperature trends at four layers in the global ocean[/caption]

The Pacific Ocean is the primary source of the subsurface warm water found in the study, though some of that water now has been pushed to the Indian Ocean. Since 2003, unusually strong trade winds and other climatic features have been piling up warm water in the upper 1,000 feet of the western Pacific, pinning it against Asia and Australia.

"The western Pacific got so warm that some of the warm water is leaking into the Indian Ocean through the Indonesian archipelago," said Nieves, the lead author of the study.

The movement of the warm Pacific water westward pulled heat away from the surface waters of the central and eastern Pacific, which resulted in unusually cool surface temperatures during the last decade. Because the air temperature over the ocean is closely related to the ocean temperature, this provides a plausible explanation for the global cooling trend in surface temperature.

Cooler surface temperatures also are related to a long-lived climatic pattern called the Pacific Decadal Oscillation, which moves in a 20- to 30-year cycle. It has been in a cool phase during the entire time surface temperatures showed cooling, bringing cooler-than-normal water to the eastern Pacific and warmer water to the western side. There currently are signs the pattern may be changing to the opposite phase, with observations showing warmer-than-usual water in the eastern Pacific.

"Given the fact the Pacific Decadal Oscillation seems to be shifting to a warm phase, ocean heating in the Pacific will definitely drive a major surge in global surface warming," Nieves said.

Previous attempts to explain the global surface temperature cooling trend have relied more heavily on climate model results or a combination of modeling and observations, which may be better at simulating long-term impacts over many decades and centuries. This study relied on observations, which are better for showing shorter-term changes over 10 to 20 years. In shorter time spans, natural variations such as the recent slowdown in global surface temperature trends can have larger regional impacts on climate than human-caused warming. NASA: Oceans Slowed Global Temperature Rise

Pauses of a decade or more in Earth's average surface temperature warming have happened before in modern times, with one occurring between the mid-1940s and late 1970s.

"In the long term, there is robust evidence of unabated global warming," Nieves said.

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. NASA develops new ways to observe and study Earth's interconnected natural systems with long-term data records. The agency freely shares this unique knowledge and works with institutions around the world to gain new insights into how our planet is changing.

Battle Over Fracking Shaping Up In Colorado. Environmentalists and the energy industry have fought decisive battles over fracking in New York, Oklahoma and Texas, but the outcome is unclear in Colorado, where the issue could go to a ballot fight in the 2016 election.
A task force convened by Colorado Gov. John Hickenlooper tried to find a compromise over who should regulate the industry - the state or local government - and to what extent. But fracking critics were bitterly disappointed when the panel suggested leaving regulatory power in state hands and avoided recommending specific health, environmental and safety rules. Battle Over Fracking Shaping Up In Colorado
"I think the fossil fuels industry won," said Karen Dike, a member of Coloradans Against Fracking.
Fracking is a pressing issue in Colorado, the nation's No. 7 energy-producing state. Along the urban Front Range, expanding suburbs and booming oilfields are running into each other, and drilling rigs sometimes show up near public schools. Several municipal attempts to ban fracking have failed, and the industry warns that local control would stifle energy development.
Dike and others won't say whether they plan to put measures that would restrict fracking on the 2016 ballot, but they don't rule it out.
Frank McNulty, a Republican former state lawmaker who sponsored a pro-industry ballot measure in 2014, expects fracking opponents to turn to voters next year.
"I don't think that it's settled," he said.
Fracking, or hydraulic fracturing, injects water, sand and chemicals under high pressure to crack open underground formations and make it easier to recover oil and gas. The industry says it's safe.
Opponents won a significant victory in New York, where regulators formalized a statewide fracking ban on June 29, citing environmental and public health risks.
In May, the industry prevailed in Texas and Oklahoma, where new state laws prevent local governments from banning fracking.
Colorado hasn't imposed sweeping measures favoring either side, in part because of a nearly even three-way electoral split among Republican, Democratic and unaffiliated voters.
Colorado has plenty of advocates on opposite ends of the argument, but "also a very sizable middle ground, people who are willing to talk through it," said Christopher Weible, an associate professor at the University of Colorado-Denver School of Public Affairs who studies fracking policy debates. "Maybe it's a thing about Colorado, maybe we have a lot of pride in our natural resources and how we can get along."
Hickenlooper, a Democrat and an energy industry supporter, formed the task force last year. Competing ballot issues on fracking threatened to draw a wave of conservative voters and campaign donations into the 2014 election, so Hickenlooper negotiated a truce: Both sides withdrew their ballot issues and the task force went to work.
After five months of meetings, the panel suggested giving local governments a consulting role but not the power to set their own oil and gas rules. The task force rejected proposals to require disclosure of all the chemicals used in fracking and to give surface property owners more leverage if someone else owns the minerals under their land and wants to drill.
Hickenlooper praised the recommendations, but <a href="https://www.bing.com/search?q=democratic&amp;cvid=24d83deb85834cb9b3e5dd13e09510b8&amp;FORM=ANAB01&amp;PC=HCTS">Democratic</a> congressman Jared Polis, who favors more restrictions, was disappointed. Polis supported ballot issues in 2014 that would have given local governments more control and required new wells to be at least 2,000 feet from houses, but withdrew them in the truce.
Polis said fracking could be on the 2016 ballot if state officials don't further regulate the industry. He stopped short of saying whether he would organize the effort, but he wants lawmakers and regulators to adopt three proposals that weren't formally recommended by the task force.
One would let local governments impose stricter rules than the Colorado Oil and Gas Conservation <a href="http://www.earth.com/earthpedia-articles/african-wild-dog-vs-hyena-know-the-difference/">Commission</a>, charged with regulating drilling statewide. Another would change the commission's role from facilitating oil and gas development to simply regulating it. The third would set up a panel to resolve disputes between energy companies and local governments or property owners before they land in court.
If opponents try to limit fracking in 2016, McNulty said he'll fight them. He co-sponsored a 2014 ballot issue to deny oil and gas tax revenues to local governments that ban drilling, but withdrew it as part of Hickenlooper's compromise.
Colorado already has some of the toughest energy regulations in the country, said Dan Haley, CEO of the Colorado Oil and Gas Association, an industry group.
"We choose to work together with communities to find solutions for concerned citizens, and not to worry about the activists who just want to put industry families on the unemployment line," he said.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;



The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.
