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.

Gulf States Reach $18.7 Billion Settlement Over BP Oil Spill. BP and five Gulf states announced an $18.7 billion settlement Thursday that resolves years of legal fighting over the environmental and economic damage done by the energy giant's oil spill in 2010.
The BP oil spill settlement money will be used to resolve the Clean Water Act penalties; resolve natural resources damage claims; settle economic claims; and resolve economic damage claims of local governments, according to an outline filed in federal court. The settlement involves Florida, Alabama, Mississippi, Louisiana and <a href="http://www.earth.com/video/earth-from-space-houston-texas/">Texas</a>. Gulf States Reach $18.7 Billion Settlement Over BP Oil Spill
"If approved by the court, this settlement would be the largest settlement with a single entity in American history; it would help repair the damage done to the Gulf economy, fisheries, wetlands and wildlife; and it would bring lasting benefits to the Gulf region for generations to come," U.S. Attorney General Loretta Lynch said in a statement.
The settlement announcement comes as a federal judge was preparing to rule on how much BP owed in federal Clean Water Act penalties. The judge had already found that 3.19 million barrels of oil - nearly 134 million gallons - spewed into the Gulf. Individual states also were pursuing litigation.
BP PLC chairman Carl-Henric Svanberg said the settlement reflected the company's commitment to restoring the Gulf of Mexico economically and environmentally, and provided the company with closure going forward.
"It resolves the company's largest remaining legal exposures, provides clarity on costs and creates certainty of payment for all parties involved," Svanberg said.
The company had argued against a high Clean Water Act penalty, saying its spill-related costs already were expected to exceed $42 billion. It's also unclear how much BP will end up paying under a 2012 settlement with individuals and businesses claiming spill-related losses.
Costs incurred by BP so far include an estimated $14 billion for response and cleanup and $4.5 billion in penalties announced after a settlement of a criminal case with the government.
In 2012, BP reached the settlement with plaintiff's lawyers over economic and property damage claims arising from the spill. In its first-quarter earnings report for 2015, BP said it could estimate at least a $10.3 billion cost. But it also stressed that the cost could be higher, depending on how many legitimate claims were filed by a recently passed deadline.

Polar Bears In Imminent Danger From Global Warming. About a third of the world's polar bears could be in imminent danger from greenhouse gas emissions in as soon as a decade, a U.S. <a href="https://www.bing.com/search?q=government&amp;cvid=0f92c82780c04d62964141a94ee4706a&amp;FORM=ANAB01&amp;PC=HCTS">government</a> report shows.
The U.S. Geological Survey, the Interior Department's research arm, said updated scientific models don't bode well for polar bear populations across the world, especially in Alaska, the only state in the nation with the white bears. Polar Bears In Imminent Danger From Global Warming
The report released this week is part of the U.S. Fish and <a href="http://www.earth.com/news/some-cat-owners-care-about-their-pets-impact-on-wildlife-conservation/">Wildlife</a> Service's recovery plan for the polar bear. It is expected to be published Thursday in the Federal Register. Polar Bears In Imminent Danger From Global Warming
Greenhouse gases are blamed for the climate warming that's reducing the polar bear's summer sea ice habitat.
The effects of diminished sea ice will lead to population declines throughout the century. Scientists saw no rebound in population numbers in the projections that stretched to the year 2100.
The scientific models attempted to predict the effects on polar bear populations under two scenarios: one in which greenhouse gas emissions stabilized, and the other in which they continued unabated.
Under either scenario, the bears in the Alaska, Russia and Norway group - with an estimated population of about 8,500 - would start to be affected in either 2025 or 2030, said lead author Todd Atwood, an Alaska-based USGS research wildlife biologist.
He said the main reason is this part of the Arctic has suffered some of the most dramatic declines in summer sea ice.
Polar bears feed primarily on seals and use sea ice for feeding, mating and giving birth. When the sea ice retreats in the summer, polar bears are forced to land. A study earlier this year found the land-based food would not help a polar bear adapt to the loss of sea ice. The Office of Naval Research said the past eight years have had the eight lowest amounts of summer sea ice on record.
The USGS didn't predict specific number declines and instead projected whether a population would see a decreased or a greatly decreased population.
"That's not to say that we'll lose polar bears completely out of the area, but we think that they'll be at a greatly decreased distribution than what they currently are," Atwood said.
Polar bears in Canada and Greenland also could see dramatic population drops by 2050. Bears in the high Canadian Arctic fared the best in the two scientific models. They saw a "greatly decreased" population only under the worst-case scenario.
"Polar bears are in big trouble," said Rebecca Noblin, Alaska director for the Center for Biological Diversity. "There are other steps we can take to slow the decline of polar bears, but in the long run, the only way to save polar bears in the Arctic is to reduce greenhouse gas emissions."
The Center for Biological Diversity originally petitioned for polar bears to be listed as threatened under the Endangered Species Act. In 2008, the species became the first to be listed because of global warming.

Man-Made Landscapes Promote Bird Species Loss. Research led by the University of Exeter has found a substantial reduction in bird species living in cultivated mango orchards compared to natural habitats in Southern Africa. The results, which are published today in the journal Landscape Ecology, highlight the value of assessing habitats prior to land use change to predict the impact of agriculture on biodiversity.

The researchers monitored bird populations across cultivated mango orchards and natural habitats in the Kruger to Canyons Biosphere region in <a href="https://www.bing.com/search?q=south+africa&amp;cvid=7b7d8ba979714cab87fa14eff0497f2b&amp;FORM=ANAB01&amp;PC=HCTS">South Africa</a>. They found that replacing a natural habitat with an agricultural landscape can result in a substantial decline in the richness of species living within the region. Man-Made Landscapes Promote Bird Species Loss

The scientists were aiming to ascertain whether agriculture could add novel habitat elements and thereby support additional bird species complementary to those already present in the natural areas - but found that in contrast, there was a loss of 35% of the bird species within the farmed land.

One of the study's authors, Dr Frank Van Veen of the Centre for Ecology and Conservation at the University of Exeter, said: "Mango orchards are missing the low level woody scrub found in natural vegetation and the birds missing from the orchards are exactly those that have a life-style that depends on this layer of vegetation. These results show that simply measuring the vertical vegetation structure can help to predict negative effects of agriculture on biodiversity and suggest ways to mitigate these."

"This loss of richness has implications for the preservation and provision of the ecosystem, in particular pest control, seed dispersal and pollination. It is thus crucial for policy makers in countries such as South Africa, where natural habitats remain the predominant landscape features, to identify management strategies that provide the best balance between crop productivity and biodiversity conservation in the context of sustainable agriculture."

During the study, the team conducted 150 counts each at both natural habitat and mango orchard locations and measured aspects of habitat structure. Across all 300 survey points, a total of 14,278 birds representing 151 species were recorded. The results indicate that the lack of low level woody scrub in the mango orchards could account for the absence of some 26 insectivorous and nectarivorous species.

The diversity and abundance of bird species were both greater in natural habitats than in mango orchards, and whilst approximately a third of species recorded in the natural sites were unique to this habitat, there were no species unique to mango orchards.

Study author Yvette Ehlers Smith of the University of Exeter and The University of KwaZulu-Natal in South Africa added: "Our findings suggest that knowledge of habitat structure, along with species' life history traits can provide a predictive framework for effects that anthropogenic habitats may have on regional biodiversity, and allow management to reduce negative effects."

"The consequences of farmland management will have critical effects on conservation planning for biodiversity, as well as implications for food security. We recommend the inclusion of patches of natural vegetation, for example hedgerows, surrounding and within agricultural landscapes to increase habitat diversity and maintain natural levels of species richness."

Green Movement Entering Sports Through Green Sports Alliance. Andrew Ference was at the beginning of his NHL career when he met Dr. David Suzuki, who hosts a TV show in Canada. The conversation with the award-winning scientist changed the life of the young defenseman.
Ference told Suzuki about all the ways he's environmentally responsible at home. The famous environmentalist responded with a shrug.
"I was really patting myself on the back, and he just kind of looked at me and said `So what?'" Ference recalled. "He's like `Are you telling anybody about it? Are you inspiring other people to do it? Here you are, a hockey player in Canada and you have such an opportunity to stand for something good. I mean what do you do?' And I didn't have an answer."
The push from Suzuki inspired Ference to become one of the leading voices in the green movement in sports. The captain of the Edmonton Oilers started an initiative with the NHL Players Association to encourage his colleagues to go carbon neutral. He spoke in schools about the virtues of composting and renewable energy, and studied sustainability at Harvard.
Decades after he collected bottles to take to the recycling depot for money while he was growing up in Edmonton, Ference participated in an NHL panel at the fifth annual Green Sports Alliance Summit this week. He gave one of the keynote addresses at the conference attended by business and sports leaders across the country.
"Things have moved fast here in the last decade of people's awareness of sustainability," the 36-year-old Ference said. "Nobody used that word a decade ago. It wasn't just a common thing to use in everyday conversation, let alone corporate talk. And so the hockey world just kind of (came) along with the rest of the world."
What was once a small conversation about how sports affects the environment and vice versa has turned into an organized wave that influences the plans and construction of major sports venues around the country. The Natural Resources Defense Council, which helped create the Green Sports Alliance in 2010, advises the NFL, NBA, NHL, Major League Baseball and other leagues on green issues. The Green Sports Alliance has about 300 members.
"This movement is growing in membership. It's growing in influence," said Dr. Allen Hershkowitz, the president of the Green Sports Alliance.
The NHL launched its green platform in 2010, and Hershkowitz said it has developed into "arguably the most robust leaguewide environmental program of any sports league or federation in the world." It focuses on increasing the energy efficiency and lowering the carbon footprint in each of its buildings, and engaging with fans and corporate and marketing partners in a substantive way.
"We are a sport that traces its roots to frozen ponds and cold climates, and while most of our games are played indoors now, the fact is the future of our game we believe depends on sustainable environmental practices," NHL Commissioner Gary Bettman said.
Omar Mitchell, the senior director of sustainability for the league, said the NHL counterbalances its carbon footprint through the purchase of renewable energy certificates and carbon offsets as part of its partnership with Constellation, an energy company. Mitchell declined to disclose the cost of the RECs and offsets, but the NHL's energy program is believed to be the only one of its kind among the major North American sports leagues.
"That's our way of saying that we recognize what our footprint is, we recognize that we do have an environmental impact, and this is one way of mitigating those impacts," Mitchell said.
While sports leagues, teams and venues have come a long way - "From an environmental perspective, it is the golden age of stadium and arena design," Hershkowitz said - the industry still has a significant environmental impact around the world. Huge crowds at sports events produce a variety of environmental issues, and other concerns range from transportation for teams to simple care of the fields.
Two major topics at the summit in Chicago were food and transportation. The NRDC and GSA released a report highlighting increased sustainable food options at several major sports venues. There also was talk about partnerships between teams and public transit outlets.
"The systematic approach and the strategic approach that many sports people undertake are keep working and plugging away with the back-office operation at the same time making those public ones visible as long as you're doing them the right way," said Dr. Michael Pfahl, an associate professor in the department of sports administration at Ohio University.
Cost and access are two of the biggest problems when it comes to the green movement and the sports industry. While those are common problems, Hershkowitz thinks sports can be a positive force for change when it comes to environmental infrastructure.
"Are the sports venues the deciding factor in whether a city adopts a recycling ordinance or develops a composting facility? Probably not," he said. "Is a sports facility the deciding factor in having a city invest in mass transit? Probably not. But does the market and local influence of a prominent sports team, professional sports team or collegiate team, is that noticed by city planners? Absolutely."

Global Warming Causing Dramatic Changes To Arctic Tundra. Significant changes in one of the Earth's most important ecosystems are not only a symptom of climate change, but may fuel further warming, research suggests.

One of the biggest studies to date of key vegetation in the <a href="http://www.earth.com/news/antarctic-icebergs-affect-seawater-and-ocean-currents-far-from-the-continent/">Arctic</a> tundra provides strong evidence that dramatic changes in the region are being driven by climate warming.

Studies of tundra shrubs - which act as a barometer of the Arctic environment - show that they grow more when temperatures are warmer. Increased shrub growth, driven by recent and future warming in the Arctic, could cause more warming in tundra ecosystems and for the planet as a whole.

Taller shrubs prevent snow from reflecting heat from the sun back into space, warming the Earth's surface. They can also influence soil temperatures and thaw permafrost. Increased shrubs can change the cycling of nutrients and carbon in soil, affecting its decomposition and the amount of carbon released to the atmosphere. All these factors can contribute to climate warming both in the Arctic and on a global scale.

Shrub species in wet landscapes at mid-latitudes of the Arctic are the most sensitive to climate warming, the study found. These areas are vulnerable to change as they store large amounts of carbon in frozen soil, which could be released by warming and permafrost thaw.

An international team of scientists at 37 sites in nine countries, led by the University of Edinburgh, studied records of shrub growth spanning 60 years by analysing annual growth rings in the plant stems, to explore links between climate and vegetation change.

The study, published in Nature Climate Change, was funded by the International Arctic Science Committee. The findings will help improve models of future changes to tundra ecosystems and the impacts of these changes on the global climate. Global Warming Causing Dramatic Changes To Arctic Tundra

Dr Isla Myers-Smith, of the University of Edinburgh's School of GeoSciences, who co-ordinated the study, said: "Arctic shrub growth in the tundra is one of the most significant examples on Earth of the effect that climate change is having on ecosystems. Our findings show there is a lot of variation across this landscape. Understanding this should help improve predictions of climate change impacts across the tundra."

US Appeals Court Upholds EPA Chesapeake Bay Cleanup Plan. A U.S. appeals court has upheld a federal plan limiting pollution in the Chesapeake Bay despite objections from farmers who accuse the Environmental Protection Agency of abusing its power.
The ruling Monday upholds restrictions on farm and construction runoff and wastewater treatment and is a clear win for environmentalists.
Six states have agreed to the pollution limits: Delaware, Maryland, <a href="http://www.earth.com/video/earth-from-space-new-york-city/">New York</a>, Pennsylvania, Virginia and West Virginia, along with Washington, D.C.,
The American Farm Bureau Federation and others fought the restrictions. They argued that the <a href="https://www.bing.com/search?q=epa&amp;cvid=4ef98a92817545a7b879b887e83e2a4a&amp;FORM=ANAB01&amp;PC=HCTS">EPA</a> was usurping state authority to regulate waterways.
The EPA says animal waste and fertilizer that moves from streams into the Chesapeake is the single largest source of bay pollution.US Appeals Court Upholds EPA Chesapeake Bay Cleanup Plan
Third Circuit Judge Thomas Ambro says Chesapeake Bay pollution is a complex problem that affects more than 17 million people. The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles.

Warm Ocean Temperatures A Huge Threat For Coral Reefs. Abnormally warm ocean temperatures are creating conditions that threaten to kill coral across the equatorial Pacific, north Pacific and western Atlantic oceans, the National Oceanic and Atmospheric Administration said Monday.
Coral bleaching occurs when coral is stressed by changes in its environment, causing it to release algae living in its tissue. The coral then turns pale or white and becomes more susceptible to disease. In severe cases, the coral can die, permanently changing the habitat for fish and shellfish.
"The bleaching that started in June 2014 has been really bad for corals in the western Pacific," said Mark Eakin, NOAA's Coral Reef Watch coordinator, in news release Monday. "We are worried that bleaching will spread to the western <a href="http://www.earth.com/image/the-2020-atlantic-hurricane-season-was-supercharged/">Atlantic</a> and again into Hawaii." Warm Ocean Temperatures A Huge Threat For Coral Reefs
Ocean temperatures, light and nutrient levels can cause bleaching. But NOAA says only warm temperatures can cause the widespread bleaching that scientists have been seeing since last year.
In 2014, Hawaii experienced widespread bleaching for the first time in nearly two decades. If it happens again this year, it would be the first time in history the Hawaiian Islands saw consecutive years of bleaching, NOAA says.
Coral can recover from mild bleaching, but two consecutive years of bleaching could cause severe damage, scientists say.
"Many healthy, resilient coral reefs can withstand bleaching as long as they have time to recover," Eakin said. "However, when you have repeated bleaching on a reef within a short period of time, it's very hard for the corals to recover and survive."
In 2014, Kaneohe Bay on Oahu's east side suffered the most serious bleaching in the state, which is home to 15 percent of all coral under U.S. jurisdiction. Seventy-five percent of the dominant coral species there lost some color or turned completely white.
Coral reefs are a critical part of the ecosystem, and their health is vital to the ocean environment. Coral cover just one-tenth of the ocean floor, but they are home to 25 percent of known marine species. Some fish eat coral, and others hide from predators in them. Some species use coral as nursery grounds. Some types of shark will frequent coral reefs.

Expansion Of Rubber Industry Is Risky Environmental Business. Researchers say policy interventions may be necessary to protect local economies and ecosystems from the pitfalls of rubber expansion.

Despite the proliferation of synthetics, industrially superior traditional rubber remains king. Accordingly, prices remain high.

As a result, rubber production has slowly been expanding out of its comfort zone in the tropics of Indonesia and into more marginal production regions of continental Southeast Asia.

While the lure of the seemingly limitless demand for rubber has persuaded many to convert farmland and forests into rubber plantations, researchers suggest real profits are elusive. Expansion Of Rubber Industry Is Risky Environmental Business

New research by scientists from the World Agroforestry Center (ICRAF) suggests widespread land conversion for rubber production could put farmers' livelihoods at risk, leaving them with a less stable food supply and fewer sources of income. Furthermore, researchers say global warming is likely to make marginal rubber production land even less profitable.

Even more obvious, researchers suggest, are the environmental costs of rubber expansion. Expanding rubber operations are destroying forests and previously protected wilderness in Southeast Asia and southern China -- shrinking the carbon-absorbing benefits of dense forest, as well as diminishing soil productivity, water availability, and biodiversity.

"There is clear potential for loss-loss scenarios when forest is being cleared for rubber plantations that are not economically sustainable, and that have negative impacts on soils and water balance," researcher Antje Ahrends, a scienitst with the Royal Botanic Garden Edinburgh and the World Agroforestry Center, <a class="tpstyle" href="http://worldagroforestry.org/newsroom/press-releases/new-research-rubber-expansion-threatens-biodiversity-and-livelihoods" target="_blank" rel="noopener noreferrer">said in a press release</a>.

A report on the economic and environmental consequences of rubber expansion was published this week <a class="tpstyle" href="http://www.sciencedirect.com/science/article/pii/S0959378015000801" target="_blank" rel="noopener noreferrer">in the journal Global Environmental Change</a>.

Researchers in China, Europe and elsewhere say policy interventions may be necessary to protect local economies and ecosystems from the pitfalls of rubber expansion.

"Oil palm has received much more global attention than rubber, but in fact environmental and social impacts are comparable and the dynamics of the two are related," explained Meine Van Noordwijk, chief science advisor at ICRAF. "It may be time for a roundtable on sustainable rubber where the private sector, public parties and scientists can try to bridge the various interests and agree on standards."

How Do Perennial Biofuel Crops Affect Water Cycles. There are costs and benefits for every land management decision. In the Midwest, researchers wanted to better understand the costs of planting perennial biofuel crops like switchgrass or native grasses.

Their work suggests in one category, at least, biofuel crops and corn are equal. Both have a similar water-usage footprint.

When biofuels are burned, less carbon dioxide is released into the atmosphere than is released by fossil fuels. But are biofuels a net positive? To know for sure, researchers need to more accurately calculate the energy required to grow biofuel crops and how their production affects the environment.

Recently, researchers at Michigan State University looked at how switchgrass and other biofuel plants affect the water cycle in the upper Midwest. To measure their affects, scientists installed water sensors in the soil of a number for farm fields in Michigan.

The sensors helped scientists calculate how much water made its way to the water table and how much evaporated back into the atmosphere.

"When we established the different cropping systems in 2008, we installed soil-water sensors at various depths through the root zone," Stephen Hamilton, a scientist at the Great Lakes Bioenergy Research Center, <a class="tpstyle" href="http://msutoday.msu.edu/news/2015/perennial-biofuel-crops-water-consumption-similar-to-corn/?utm_campaign=media-pitch&amp;utm_medium=email" target="_blank" rel="noopener noreferrer">said in a press release</a>. "We've been continuously monitoring the soil water content ever since."

Hamilton and his colleagues found that biofuel crops like switchgrass, miscanthus, native grasses, restored prairies and hybrid poplar trees use roughly the same amount of water as corn crops.

"The message here," Hamilton said, "is that in many settings, perennials may not use more water. For well-drained soils in the upper Midwest at least, and probably for eastern North America in general, these results most likely apply, and water balance would not be adversely affected."

The new research was published this week <a class="tpstyle" href="http://iopscience.iop.org/1748-9326/10/6/064015/article" target="_blank" rel="noopener noreferrer">in the journal Environmental Research Letters</a>.

Judge Refuses To Dismiss Gulf Oil Leak Lawsuit. A federal judge refused on Tuesday to dismiss a lawsuit that environmental groups filed against a New Orleans-based company responsible for a decade-old oil leak in the Gulf of Mexico.
U.S. District Judge Susie Morgan ruled that a trial is necessary to determine whether several plaintiffs led by the <a href="http://www.earth.com/video/earth-from-space-new-york-city/">New York</a>-based Waterkeeper Alliance have a right to sue Taylor Energy Company.
The company has claimed federal regulators agree nothing more can be done to stop its leak off Louisiana's coast. But Morgan concluded there is a "genuine factual dispute" over whether Taylor can and should do more to mitigate its impacts. Judge Refuses To Dismiss Gulf <a href="https://www.bing.com/search?q=oil&amp;cvid=723a982b267a48e7a111102c079589cb&amp;FORM=ANAB01&amp;PC=HCTS">Oil</a> Leak Lawsuit
Since 2004, oil has been leaking at the site where a Taylor-owned platform toppled during Hurricane Ivan. A mudslide triggered by Ivan's waves also buried a cluster of oil wells under mounds of sediment.
Authorities estimate the leak could last a century or more if left unchecked. The Coast Guard has ordered the company to design and install a better system for collecting oil before it reaches the water's surface.
In April, an investigation by The Associated Press revealed evidence that the leak is worse than Taylor, or the government, have publicly reported. Presented with AP's findings, the Coast Guard provided a new leak estimate that is about 20 times greater than one recently touted by the company in a court filing.
Taylor Energy sold all its offshore leases and oil and gas interests in 2008, four years after founder Patrick Taylor died. The company says it is no longer active in the offshore industry and it only exists to continue addressing the leak.
Morgan, however, said that position isn't consistent with the company's argument that many leak-related documents must remain under wraps to protect valuable trade secrets.
"If Taylor has ceased to operate as an oil producer, the Court questions whether information related to oil production should remain confidential," she wrote.
A biologist, a tour guide and a fisherman are named as plaintiffs in the suit. The company claims they lack the legal "standing" to sue over alleged Clean Water Act violations.
A trial for the case is scheduled to start on Oct. 5, with Morgan hearing testimony and deciding the case without a jury.

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."

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;

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."

Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

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."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;

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.
