The inclusion of fiber in the diet has been linked to a variety of health perks for decades. The body needs this essential nutrient to keep digestion running smoothly and maintain steady blood sugar levels.&nbsp;



Most experts recommend at least 25 grams per day for women and 38 grams for men, yet many adults in the United States barely reach half that goal. But there is more to this story than a happy belly or balanced glucose.&nbsp;



A recent study in Nature Metabolism shows that fiber may also leave a mark on our genes.



<h2 class="wp-block-heading" id="h-why-fiber-still-matters">Why fiber still matters</h2>



Fiber comes in many forms, from the crunchy stems of leafy greens to the chewy shells of beans and nuts. <a href="https://www.earth.com/news/want-to-lose-weight-try-eating-more-protein-and-fiber/" target="_blank" rel="noreferrer noopener">Dietary fiber</a> travels to the large intestine, where friendly bacteria feast on it.&nbsp;



This feast produces short-chain fatty acids, including propionate and butyrate, which have gained attention recently for their effects on gut health.



Researchers have been eager to see whether these acids from fibers impact genes beyond basic energy production.



<h2 class="wp-block-heading" id="h-fiber-gut-and-fatty-acids">Fiber, gut, and fatty acids</h2>



The science behind short-chain fatty acids and genes has intrigued experts for years, and now <a href="https://med.stanford.edu/profiles/michael-snyder" target="_blank" rel="noreferrer noopener">Michael Snyder</a>, Stanford B. Ascherman Professor of Genetics at <a href="https://www.stanford.edu" target="_blank" rel="noreferrer noopener">Stanford University</a>, has shed more light on it through this project. 



His team traced the biological footprints of propionate and butyrate in both <a href="https://www.earth.com/news/fiber-rich-diets-reduce-antimicrobial-resistance-in-the-gut/" target="_blank" rel="noreferrer noopener">normal cells</a> and cancer cells. 



The aim was to see how these acids might switch genes on or off in ways that influence the growth and survival of cells.



<h2 class="wp-block-heading" id="h-how-fiber-impacts-genes-nbsp">How fiber impacts genes&nbsp;</h2>



Short-chain fatty acids are generated when gut microbes break down fiber. They move into the bloodstream and can reach different tissues.&nbsp;



The study found that propionate and butyrate attach to certain sites on histones - which are proteins that act like spools for DNA - causing direct modifications on genes related to cell division and cell death.



“We found a direct link between eating fiber and modulation of gene function that has anti-cancer effects,” said Snyder.



Instead of simply describing fiber’s link to good health, the researchers pinpointed the exact molecular changes behind those benefits.



<h2 class="wp-block-heading" id="h-preventing-uncontrolled-cell-growth">Preventing uncontrolled cell growth</h2>



Cancer often begins when cells lose their usual checks and balances. Normal cells are expected to grow, specialize, and sometimes self-destruct if there’s a problem.&nbsp;



When those processes go haywire, mutated cells can survive too long or multiply too fast. The study uncovered how certain chemical markers on genes for cell regulation might switch in a protective way when these short-chain fatty acids are around.



It is generally the case that people’s diets are very poor in fiber. Adjusting meal plans to include foods like beans, nuts, <a href="https://www.earth.com/news/certain-vegetables-protect-us-from-illness-by-strengthening-the-lung-barrier/" target="_blank" rel="noreferrer noopener">cruciferous vegetables</a>, or <a href="https://www.earth.com/news/eating-one-avocado-each-day-can-add-years-to-your-life/" target="_blank" rel="noreferrer noopener">avocados</a> may promote the production of more of these acids, potentially offering some defense against abnormal cell growth.



<h2 class="wp-block-heading" id="h-why-gut-and-genes-might-need-more-fiber">Why gut and genes might need more fiber</h2>



A diet that skimps on fiber starves the microbes that produce these beneficial fatty acids. Low levels can reduce the supply of butyrate and propionate.



That could leave you short on important chemical signals that appear to help keep unwanted cellular behavior under control.&nbsp;



According to the <a href="https://nutritionsource.hsph.harvard.edu/carbohydrates/fiber/" target="_blank" rel="noreferrer noopener">Harvard T.H. Chan School of Public Health</a>, most Americans only consume around 15 grams of fiber daily, which falls short of <a href="https://nutritionsource.hsph.harvard.edu/carbohydrates/fiber/" target="_blank" rel="noreferrer noopener">recommended amounts</a>.



<h2 class="wp-block-heading" id="h-cancer-risk-and-fiber-s-gene-protective-role">Cancer risk and fiber’s gene-protective role</h2>



Colon cancer is a <a href="https://www.earth.com/news/the-cooking-oils-in-your-diet-may-be-linked-to-cancer/" target="_blank" rel="noreferrer noopener">concern for many adults</a>. The <a href="https://www.cancer.org/cancer/colon-rectal-cancer.html" target="_blank" rel="noreferrer noopener">American Cancer Society</a> estimates that about 1 in 23 men and 1 in 25 women will be diagnosed with colon cancer at some point in their lifetime. 



This new study provides a window into how the byproducts of fiber breakdown might influence gene behavior in the colon, and possibly other tissues, in a helpful way.



“By identifying the gene targets of these important molecules we can understand how fiber exerts its beneficial effects,” said Snyder.&nbsp;



Although more work is needed to confirm how each type of fiber interacts with the gut and the rest of the body, this adds to growing evidence that diet and cancer risk are tightly woven together.



<h2 class="wp-block-heading" id="h-connection-between-diet-gut-and-genes">Connection between diet, gut, and genes</h2>



The research highlights the importance of diet as a modulator of genetic signals. 



It also emphasizes potential opportunities for personalized strategies that combine better eating habits with therapies aimed at correcting harmful gene activity.&nbsp;



Many clinicians see fiber as a key feature of a balanced diet, and these findings may prompt more specific guidelines on how much and which types of fiber are most valuable for long-term health.



<h2 class="wp-block-heading" id="h-what-foods-can-boost-fiber-intake">What foods can boost fiber intake?</h2>



Whole grains, nuts, seeds, and legumes remain <a href="https://www.earth.com/news/ketogenic-diet-may-help-the-body-kill-cancer-cells/" target="_blank" rel="noreferrer noopener">top options</a> for boosting your daily fiber count. Vegetables like Brussels sprouts and broccoli, as well as fruits such as raspberries, also offer generous amounts.&nbsp;



Even small shifts like opting for a whole-wheat tortilla instead of a white-flour tortilla can push your numbers up. 



For individuals who struggle to reach recommended targets, talking with a healthcare provider or a registered dietitian can point the way to practical changes that nourish both you and your gut bacteria.



People sometimes balk at the thought of adding more plant-based foods to their <a href="https://www.earth.com/news/which-dietary-changes-are-best-for-cancer-prevention/" target="_blank" rel="noreferrer noopener">diet</a>. But a gradual introduction may help your gut adjust without uncomfortable bloating or gas.&nbsp;



Your digestive system, along with your genes, could benefit from these simple swaps, especially as ongoing research on fiber clarifies the links between short-chain fatty acids and various cellular pathways.



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



All signs suggest that fiber is more than just a helper for digestion. These insights about short-chain fatty acids may prompt further collaboration between nutrition science and genetics.&nbsp;



By paying attention to what our microbes need, we may discover fresh paths to protect our cells from harm. The study is published in <a href="https://www.nature.com/articles/s42255-024-01191-9" target="_blank" rel="noreferrer noopener">Nature Metabolism</a>.

Eating enough fiber prevents cancer in a surprising way

The inclusion of fiber in the diet has been linked to a variety of health perks for decades.

Oil Spill Stains California Coastline, Cleanup Efforts Underway. Slicks of oil that spilled into California coastal waters from an onshore pipeline spanned a total of 9 miles Wednesday, and a company official said the line was operating at full capacity when it broke, suggesting much more oil escaped than initially estimated.
The oil that spilled Tuesday off southern Santa Barbara County formed two slicks, said Coast Guard Capt. Jennifer Williams, one of two federal response coordinators.
Before a morning flyover, the oil was estimated to span 4 miles of ocean.
The spill from a Plains All American Pipeline LP pipe was initially estimated at 21,000 gallons, but officials were not relying on that. <a href="http://www.earth.com/news/unhealthy-foods-spoil-the-benefits-of-a-mediterranean-diet/">Oil</a> Spill Stains California Coastline, Cleanup Efforts Underway
Company official Darren Palmer said Wednesday it remained unknown how much oil actually spilled.
But he said the pipeline was running at a rate of 2,000 barrels an hour - equivalent to 84,000 gallons.
The pipe was built in 1991 and underwent integrity testing a few weeks ago, he said.
Palmer said the company took responsibility for the spill and would pay for the cleanup.

(AP Photo/Michael A. Mariant)[/caption]
Workers from an environmental cleanup company strapped on boots and gloves and picked up shovels and rakes Wednesday to tackle the gobs of goo stuck to sand and rocks along Refugio State Beach.
The rupture happened on the same stretch of coastline as a 1969 spill that was the largest ever in U.S. waters at the time and is credited with giving rise to the American environmental movement.
Members of the International Bird Rescue organization also were on hand Wednesday to clean any birds that become covered with oil, though none were immediately spotted in the calm seas that produced small waves.
Fan Yang, 26, of Indianapolis, stood on a bluff overlooking the beach, where the stench of petroleum was heavy.
"It smells like what they use to pave the roads," said Yang, who was hoping to find cleaner beaches in Santa Barbara. "I'm sad for the birds - if they lose their habitat."
The broken 24-inch pipeline spewed oil down a storm drain and into the Pacific Ocean for several hours Tuesday before it was shut off.
Authorities responding to reports of a foul smell near Refugio State Beach around noon found a half-mile slick in the ocean, county fire Capt. Dave Zaniboni said.
Plains All American Pipeline said in a statement it was making every effort to limit the environmental impact.
The state Department of Fish and Wildlife has closed fishing and shellfish harvesting for a mile east and west of the beach.
The area is home to offshore oil rigs, and small amounts of tar from natural seepage regularly show up on beaches. In 1969, several hundred thousand gallons spilled from a blowout on an oil platform and thousands of seabirds and many marine mammals were killed.
The oil industry brings risks, said Bob Deans, spokesman for the Natural Resources Defense Council.
"Santa Barbara learned that lesson over 40 years ago when offshore drilling led to disaster," he said in a statement.
The Santa Barbara-based Environmental Defense Center said having the spill occur in a sensitive and treasured environment is devastating to watch. The group was concerned about whales that migrate through the area.
"Oil spills are part of the ugly cost of fossil fuel development, made even worse by aging domestic infrastructure," said Miyoko Sakashita, oceans director for the Center for Biological Diversity.
It was unclear how long the cleanup would take and whether Refugio beach and other areas would be reopened in time for Memorial Day weekend.

Obama Says Climate Change Poses National Security Threat. President Barack Obama has argued for action on climate change as a matter of health, environmental protection and international obligation. On Wednesday, he added national security.
Those who deny global warming are putting at risk the United States and the military sworn to defend it, he told cadets at the U.S. Coast Guard Academy. Failure to act would be "dereliction of duty," their commander in chief said.
He said climate change and rising sea levels jeopardize the readiness of U.S. forces and threaten to aggravate social tensions and political instability around the globe.
The president's message to climate change skeptics was unequivocal: "Denying it or refusing to deal with it undermines our national security"
"Make no mistake, it will impact how our military defends our country," Obama said on a crisp, sunny morning at Cadet Memorial Field. "We need to act and we need to act now."
Seated before him were 218 white-uniformed graduates, pondering where military service will take them in life.
Obama drew a line from climate change to national security that had multiple strands:
-increased risk of natural disasters resulting in humanitarian crises, with the potential to increase refugee flows and worsen conflicts over food and water.
-aggravating conditions such as poverty, political instability and social tensions that can lead to terrorist activity and other violence.
-new threats to the U.S. economy from rising oceans that threaten thousands of miles of highways, roads, railways and energy facilities.
-new challenges for military bases and training areas from seas, drought and other conditions.
"Around Norfolk, high tides and storms increasingly flood parts of our Navy base and an air base," Obama said of military facilities in Virginia. "In Alaska, thawing permafrost is damaging military facilities. Out West, deeper droughts and longer wildfires could threaten training areas our troops depend on."
Preparing for and adapting to climate change won't be enough, he said. "The only way the world is going to prevent the worst effects of climate change is to slow down the warming of the planet."
He laid out his administration's steps to reduce carbon greenhouse gas emissions, including strict limits on emissions from vehicles and power plants. The government expects those emission reductions to provide the U.S. contribution to a global climate treaty that world leaders are expected to finalize in December. Obama said it doesn't take a scientist to know that climate change is happening.
The evidence is "indisputable," he said.
Without identifying the skeptics or those who resist action on climate change, Obama acknowledged the difficult terrain in Washington. "The politics will be tough, but there is no other way." He repeated: "This will be tough."
Obama's climate change agenda has drawn strong political opposition from the GOP-led Congress and faces a number of legal challenges. Many Republican lawmakers either have denied the science of climate change or have distanced themselves from it, saying they lack the expertise to issue an opinion.
Some of the 2016 GOP presidential candidates have rejected unilateral moves to address the issue, saying it could hurt the U.S. economy.
Obama had a determined and hopeful response to all of that, but one not likely to be fulfilled: "This cannot be subject to the usual politics and the usual rhetoric." Obama Says Climate Change Poses National Security Threat
His message was reinforced by Secretary of State John Kerry, just back from meetings in Asia. Kerry said in a statement that the idea of climate change as a national security issue "was a primary topic of discussion" throughout his conversations with Asian leaders.
Retired Rear Adm. David Titley, of the private Center for Climate and Security, said Obama's "rhetoric is all good," but he was waiting to see if the administration commits enough money to deal with the challenges the president identified.
Obama's appearance at the Coast Guard Academy was his second and last commencement address of the season after speaking earlier in May at a community college in South Dakota. The president traditionally delivers a commencement address every year to one of the service academies.
Later Wednesday, he was visiting Stamford, Connecticut, for a Democratic fundraiser at a private home. About 30 supporters were contributing up to $33,400 each.

California Drought Affects State's Oldest Water Rights Holders.<a href="https://www.bing.com/search?q=California&amp;cvid=67241fe5ee1942e8ab3b8c90f08f2f08&amp;FORM=ANAB01&amp;PC=HCTS"> California</a> farmers holding water rights that date as far back as the Gold Rush are bracing for their first state-ordered conservation in decades, as a record drought prompts some of the deepest cuts yet in the country's most productive agricultural state.
After telling cities and towns to slash use by 25 percent and curtailing water deliveries to some farmers and others, state officials said Wednesday they would start mandatory cuts this week to the state's oldest rights holders, historically spared from water restrictions. California Drought Affects State's Oldest Water Rights Holders
Regulators said those first orders Friday will impact holders of century-old water rights in the watershed of the San Joaquin River, which runs from the <a href="http://www.earth.com/news/sierra-nevada-mountains-taller/">Sierra Nevada</a> mountains to San Francisco Bay and is one of the main water sources for farms and communities.
Meanwhile, a second category of senior rights holders - farmers who hold longstanding claims to water because their land lies along the waterways of the Sacramento-San Joaquin river delta - are making a surprise effort to stave off that kind of curtailment order.
They are offering to voluntarily reduce their water use by a quarter. Officials promised a decision Friday on that offer, which would yield on some of the most iron-clad water rights in California, as they try to chart a path forward for a state locked in its driest four-year period on record.
"For me, 25 percent I can handle," said Gino Celli, who farms 5,000 acres of tomatoes, alfalfa and corn in the delta. "Anything more than that, man, I'm done."
It is unclear whether the farmers' offer of voluntary cuts would go far enough to save waterways that are drying up around much of the state, following a winter of below-average rainfall and record-low snows in the Sierra Nevada.
Farmers use 80 percent of all water taken from the land in California. Senior water rights holders alone consume trillions of gallons of water a year, although the state doesn't know exactly how much water they use because of unreliable data collection.
Regulators don't have widespread remote sensors or meters to make sure water isn't diverted.
The cutback orders instead are enforced by honor system and complaints. Only a fifth of junior water rights holders already told to stop pumping from the San Joaquin watershed have confirmed they were complying, a water board official said Wednesday.
Agriculture experts say they expect only modest immediate impact on food prices from any cuts to the senior water-rights holders.
Farmers will likely use their limited water to grow valuable crops - like almonds - and less valuable crops - like alfalfa - will be grown outside of California, said Jay Lund, director of the Center for Watershed Sciences at the University of California, Davis.
The mandatory cuts scheduled for Friday would be the first to the state's senior-water rights holders overall since the 1970s, and first to senior water-rights holders along the San Joaquin in memory.
"This is challenging. It's not about making everyone happy," said Felicia Marcus, chairwoman of the state Water Resources Control Board, told participants at a public hearing Wednesday on the drought. "It's about figuring out how to make terrible choices in the most fair and equitable way possible."
Board Director Tom Howard said that whatever he decides on the farmers' offer will apply beyond the river delta to the entire basin of the Sacramento River, which supplies most of the surface water in the food-producing Central Valley and the drinking water to homeowners as far south as San Diego.
That deal would not apply to hundreds of other right holders with claims to water before 1914, among few groups spared cutbacks in four years of record dry, until now.
California's water rights system - which Gov. Jerry Brown acknowledges as "somewhat archaic" - is built around the claims staked in the 19th century. Nearly 4,000 companies, farms and individuals are first in line to receive water because they made claims to water before 1914 or have property touching a waterway.
The ranks of senior water-rights holders include the cities of San Francisco and Los Angeles and rural irrigation districts that supply thousands of farms.
Regulators haven't ordered those claimants to stop pumping since 1977, during the state's last major drought. That order applied only to dozens along a stretch of the Sacramento River, and the water board has since gained new power to punish those who illegally take water, including $10,000 daily penalties.
Delta farmer Rudy Mussi already has ordered tomato plants and prepared fields, and said he needs to know how often, or if, he can water them.
"Until the fine print is out, I don't know," Mussi said Wednesday about joining the farmers' offer of 25 percent cuts. "If I can make it work, hey, I'll do my darndest."
Brown has come under criticism for sparing farmers with senior water rights from the mandatory cutbacks. Increasing amounts of the state's irrigation water goes to specialty crops like almonds, whose growers are expanding production despite the drought.
Mandatory orders could put some farmers in the Delta east of San Francisco out of business, said John Herrick, manager of the South Delta Water Agency.
When the state cutback order comes, Herrick said, the farmers will immediately try to block it in court.
"That doesn't mean we'll win," Herrick said. "But that's what we'll do."

Examining Climate Impacts of Natural Gas vs Diesel. Some major trucking companies are turning to natural gas to fuel their fleets -- and to earn "green" credit among customers. But celebrating lower emissions could be premature, according to an analysis in the ACS journal Environmental Science &amp; Technology. Researchers have found that converting heavy-duty trucks to run on natural <a href="http://www.earth.com/news/giant-animals-vanished-from-madagascar-after-humans-arrived/">gas</a> could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel's supply chain. Examining Climate Impacts of Natural Gas vs Diesel

Burning natural gas emits less carbon dioxide (CO2) into the atmosphere than other fossil fuels, but the process of getting natural gas out of the ground and delivering it through pipelines releases methane, a much more potent greenhouse gas than CO2. So, Jonathan Camuzeaux and colleagues wanted to investigate the climate impacts of switching to natural gas in different types of heavy-duty trucks.

The researchers examined a range of assumptions for methane leakage and several different kinds of commercial, natural-gas truck engines. They calculated that switching heavy-duty truck fleets from diesel to natural gas could lead to worse climate impacts over the next 50 to 90 years than remaining with diesel due to methane's high potency as a greenhouse gas in the near term. But, they added, reducing methane losses from the supply chain and improving natural gas engine efficiency could make switching fuels climate-friendly.

California Oil Spill Becoming Huge Disaster. More than 7,700 gallons of oil has been raked, skimmed and vacuumed from a spill that stretched across 9 miles of California coast, just a fraction of the sticky, stinking goo that escaped from a broken pipeline, officials said.
Up to 105,000 gallons may have leaked from the ruptured pipeline Tuesday, and up to 21,000 gallons reached the sea just north of Santa Barbara, according to estimates. The environmental impact still is being assessed, but so far there is no evidence of widespread harm to birds and sea life.
The early toll on wildlife from the California oil spill included two oil-covered pelicans, officials said. Biologists counted dead fish and crustaceans along sandy beaches and rocky shores.
The spill occurred along a long, rustic coast that forms the northern boundary of the Santa Barbara Channel, home to a rich array of sea life. Whales, dolphins, sea lions, seals, sea otters and birds such as pelicans live along the channel between the mainland and the Channel Islands, five of which are a national park surrounded by waters declared a national marine sanctuary.
Workers in protective suits have shoveled black sludge off beaches, and boats towed booms into place to corral two oil slicks. The cleanup effort continued through the night and additional crew members and boats came out early Thursday, U.S. Coast Guard Lt. Jonathan McCormick said.
They could get help from expected light winds and calm seas, said Dr. Sean Anderson, an environmental scientist at California State University, Channel Islands.
"When the water's choppy, the response gets complicated. But since the water's nice and flat, the oil sticks together and it's easier to spot and easier to pick up," he said.
Regulators and workers with Plains All American Pipeline LP, which runs the pipeline, aim to begin excavating the pipe Thursday to get their first look at the breach.
The company's chief executive visited the spill site Wednesday and apologized.
"We deeply, deeply regret that this incident has occurred at all," Chairman and CEO Greg L. Armstrong said at a news conference. "We apologize for the damage that it's done to the wildlife and to the environment."
Crude was flowing through the pipe at 54,600 gallons an hour during the leak, the company said. Company officials didn't say how long it leaked before it was discovered and shut down or discuss how fast the oil escaped.
Federal regulators from the Department of Transportation, which oversees oil pipeline safety, investigated the leak's cause, the pipe's condition and the potential violations.
The 24-inch pipe built in 1991 had no previous problems and was thoroughly inspected in 2012, according to the company. The pipe underwent similar tests about two weeks ago, though the results had not been analyzed yet.
The Los Angeles Times reported that the company accumulated 175 safety and maintenance infractions since 2006, according to federal records. The infractions involved pump failure, equipment malfunction, pipeline corrosion and operator error. The newspaper said a Plains Pipeline spokesman did not immediately respond to a request for comment about its regulatory record.
There was no estimate on the cost of the cleanup or how long it might take.
A combination of soiled beaches and the pungent stench of petroleum led officials to close popular campgrounds Refugio State Beach and El Capitan State Beach over the Memorial Day weekend.
Still, tourists pulled off the Pacific Coast Highway to eye the disaster from overlooking bluffs.
"It smells like what they use to pave the roads," said Fan Yang, of Indianapolis, who was hoping to find cleaner beaches in Santa Barbara, about 20 miles away. "I'm sad for the birds - if they lose their habitat."
The state Department of Fish and Wildlife closed fishing and shellfish harvesting for a mile east and west of Refugio beach and deployed booms to protect the nesting and foraging habitat of the snowy plover and the least tern, both endangered shore birds.
Gov. Jerry Brown on Wednesday night declared a state of emergency, a move that frees up additional state funding to help with the cleanup.
The coastline was the scene of a much larger spill in 1969 - the largest in U.S. waters at the time - that is credited with giving rise to the American environmental movement.
Environmental groups used the spill as a new opportunity to take a shot at fossil fuels and remind people of the area's notoriety with oil spills.
"Big Oil comes with big risks - from drilling to delivery," said Bob Deans, spokesman for the Natural Resources Defense Council. "Santa Barbara learned that lesson over 40 years ago when offshore drilling led to disaster."
Large offshore rigs still dot the horizon off the coast, pumping crude to shore and small amounts of tar from natural seepage regularly show up on beaches.

California Oil Spill Becoming Huge Disaster

California Oil Spill Becoming Huge Disaster. More than 7,700 gallons...

Judge: Gulf Oil Leak Details Can't Be Kept Secret. A federal magistrate judge Wednesday rejected a company's bid to preserve the confidentiality of numerous emails and reports about its failed efforts to halt a decade-old Gulf of Mexico oil leak.
The documents could be evidence in a lawsuit that a coalition of environmental groups, led by the New York City-based Waterkeeper Alliance, filed against Taylor Energy Co. The New Orleans-based company owned an oil platform that toppled during Hurricane Ivan in 2004.
An Associated Press investigation recently revealed evidence that the leak at the site of the toppled platform is worse than Taylor or government regulators had publicly reported.
U.S. Magistrate Judge Karen Wells Roby rejected a series of arguments by Taylor lawyers who said the documents contain commercially valuable trade secrets and private information - including research on efforts to stop leaks and geological information about the site.
Wells Roby didn't immediately issue a formal ruling. Once she does, Taylor can ask a district judge to review it before any documents are publicly released.
The AP has filed a public records request for some of the same confidential records.
Attorneys for the environmentalists have access to the information in question. But keeping it confidential would essentially tie attorneys' hands, restricting what they could say about the records or how they could use them at a trial set for later this year.
"It's just not practical to hold this trial in secret," said Adam Babich, a Tulane Environmental Law Clinic lawyer representing the Waterkeeper Alliance.
Documents that the alliance seeks to make public include email correspondence involving the Coast Guard, reports prepared for the government regulators overseeing the leak response efforts, expert reports by scientists and engineers and documents used by those experts in forming opinions about the spill.
The Waterkeeper Alliance sued in 2012. The group said Taylor turned over more than 15,000 pages of documents and initially stamped all but four pages as confidential under a protective order. Roby said she may order changes to the protective order, saying it is overly broad.
The lawsuit seeks penalties against Taylor for violations of the Clean Water Act in connection with the ongoing spill. Judge: Gulf Oil Leak Details Can't Be Kept Secret
A Taylor spokesman declined immediate comment after Wednesday's hearing. Phyllis Taylor, the company's chairman and CEO, declined to be interviewed Wednesday after testifying at a legislative hearing in Baton Rouge on an unrelated matter.
Last year, Taylor presented federal officials with plans for a "final resolution" at the site where a mudslide triggered by Ivan's waves also buried a cluster of oil wells under mounds of sediment. Details of that plan are among the records still under wraps, but the company has said nothing can be done to completely eliminate chronic sheens at the site.
Federal regulators suspect oil is still leaking from at least one of 25 buried wells. In 2012, officials ordered the company to install a new and improved "containment dome" to capture leaking <a href="http://www.earth.com/news/unhealthy-foods-spoil-the-benefits-of-a-mediterranean-diet/">oil</a>, but a Coast Guard document obtained by the AP said the company hadn't finished designing the new dome as of May 1.
AP also obtained a "fact sheet" prepared this month by the Interior Department that says the leak could continue for a century or more "if left unchecked."
But a company official has said that experts agree the "best course of action ... is to not take any affirmative action" due to the risks associated with additional work at the site.

California Farmers Agree To Voluntary Water Cuts. California farmers who hold some of the state's strongest water rights avoided the threat of deep mandatory cuts when the state accepted their proposal to voluntarily reduce consumption by 25 percent amid one of the worst droughts on record.
Officials hope the deal agreed upon on Friday will serve as a model for more such agreements with growers in the nation's top-producing farm state, where agriculture accounts for 80 percent of all water drawn from rivers, streams and the ground.
"We're in a drought unprecedented in our time. That's calling upon us to take unprecedented action," Felicia Marcus, chairwoman of the state Water Resources Control Board, said in announcing the agreement.
The rare concession from the farmers is the latest indication of the severity of the water shortage in California, which is suffering through its driest four years on record.
California water law is built around preserving the rights of so-called senior rights holders - farmers and others whose acreage abuts rivers and streams, or whose claims to water date back a century or more, as far back as Gold Rush days.
The offer potentially could cover hundreds of farmers in the delta of the Sacramento and San Joaquin rivers, the heart of California's water system. About 25 percent of all California river water runs through the delta, according to the state's Department of Water Resources.
Some of the farmers made the offer after state officials warned they were days away from ordering the first cuts in more than 30 years to the senior water rights holders' allotments.
The state already has ordered cities and towns to cut their water use by 25 percent, and it has curtailed water deliveries to many other farmers. But in recent weeks, many city dwellers and others have complained that agriculture should be made to share more of the sacrifice.
Rudy Mussi, whose family farms about 4,000 acres in the delta southwest of Stockton, reacted with mixed emotions about state approval of the deal.
"The 25 percent savings, that gives us certainty," Mussi said. "But at the same time I'm being asked to give up 25 percent of my paycheck."
By itself, the delta farmers' offer would not go far enough to save shrinking waterways statewide. But if more farmers sign on across the state, <a href="https://www.bing.com/search?q=California&amp;cvid=67241fe5ee1942e8ab3b8c90f08f2f08&amp;FORM=ANAB01&amp;PC=HCTS">California</a> could save significant amounts of water, since the nearly 4,000 senior water rights holders alone consume trillions of gallons a year.
The agreement "is an illustration of creative practical approaches that water managers in the state of California are taking to help get us all through this devastating drought," said Michael George, state water master for the delta.
California produces nearly half of the fruits, nuts and vegetables grown in the U.S., but agriculture experts say they would expect only modest immediate effects on food prices from any reduction in water for the senior water rights holders. Other regions would be able to make up the difference, economists say.
Under the deal, delta farmers have until June 1 to lay out how they will use 25 percent less water during the summer. That could include irrigating their crops less or leaving some of their land fallow.
In exchange, the state gave assurances to the farmers it will not cut the remaining 75 percent of the water to which they are entitled. California Farmers Agree To Voluntary Water Cuts
"When your back is up against the wall, I guess you'll do anything," said Paul Wenger, president of the California Farm Bureau Federation and an almond grower in the Modesto area, outside of the delta. He said he is skeptical the deal will protect the farmers if the drought worsens.
Senior water rights holders last saw their water cut in 1977, but that move applied only to dozens of people along a stretch of the Sacramento River.
Ellen Hanak, a water policy expert at the Public Policy Institute of California think tank, said senior water rights holders don't necessarily face complete water cutoffs, as people with less venerable claims to water have endured.
"It's important for people to realize that there are haircuts that are partial - they don't necessarily mean shaving everything off," Hanak said.
Any accord with delta farmers would probably rely largely on the honor system. California currently does not require monitoring or meters for superior rights holders.

Beijing Environment Exchange Readies Carbon Market To Fight Climate Change. Beijing Environment Exchange Readies Carbon Market To Fight Climate Change. At first, the numbers and company names flashing on a big board in Beijing's financial district suggest a booming market.
A closer look indicates otherwise: The scrolling list rotates the same dozen or so trades, all from last year.
The lights from the Beijing Environment Exchange - one of seven pilot markets in China for trading carbon - raises questions for the country as it prepares for next year's roll-out of a nationwide system that could help the world's biggest emitter of heat-trapping carbon dioxide rein in its emissions.
A successful carbon offset, or "cap-and-trade," market could play a big part in cutting <a href="http://www.earth.com/image/historic-flooding-has-killed-hundreds-across-china/">China's</a> emissions - and help the world tackle global warming.
Already launched in Europe, California and a few other spots, such carbon offset markets limit how much carbon can be emitted per year by factories and businesses. They then let those businesses that release less carbon than the cap sell to other companies permissions to emit whatever's left.
So far, the pilots have failed to make a noticeable dent in carbon emissions, with about 978 million yuan, or $158 million, traded since their launch in 2013, compared to the 7.2 billion euros, or about $8 billion, of carbon offsets that were traded in the European market in its first year of operation, 2006. Many companies required to buy carbon credits have waited until the last minute of compliance periods to make their trades, which has raised concerns about low liquidity in the market. Some observers question the reliability of data recording how much companies are emitting.
Chinese officials, however, say the pilot markets aren't meant to significantly cut the country's carbon profile yet. Instead, they say they are learning important lessons from their experiments and will use them in what will soon become the world's biggest carbon offset market.
"China is taking this step to accept its responsibility in stopping climate change," said Zhou Cheng, the Beijing exchange's vice president. "This affects industry in a legal, scientific way, and it lets them form their business plans while looking at carbon emissions too."
If anything, the national plan heralds a strategy change for a country that's so far used its one-party system to order everything from factory closures to barbecue bans by giving companies a money-making incentive to cut their carbon emissions, said Jeff Swartz, international policy director at the Geneva-based nonprofit group the International Emissions Trading Association.
For some Chinese companies, selling excess carbon offset credits could bring in millions of dollars a year.
"China is using a number of different policies, both command-and-control but also market policies," Swartz said. "(Emissions trading) will provide a fundamental solution to allow China to peak its emissions."
The past decade, however, has been a spotty one for carbon credit experiments in China.
Five years ago, European Union officials ended a carbon offset plan that paid Chinese companies to destroy the greenhouse gas HFC-23 after learning that the companies were producing the gas only to be paid to destroy it.
Kathy Kong, CEO of Beijing-based trading firm Timing Carbon, said the pilot markets still have a lot of room to grow. For example, the markets still offer only spot trading with no futures markets, which greatly limits the potential market size. Regulators must also step in to prop up falling carbon offset prices and keep prices at other times from reaching unsustainable highs.
"This is still a market created by policy," Kong said. "The policy needs to follow the market at some time."
Starting in 2013, China set up the seven pilot markets in the country's largest cities - Beijing, Tianjin, Shanghai, Chongqing and Shenzhen - as well as the industrial provinces of Guangdong and Hubei. Since mid-April, the seven markets have traded a total of 31.2 million tons of carbon. The European market in its first year traded more than 10 times that amount of carbon.
By design, each market has set up its own rules, with an eye for testing approaches for a national market.
In Beijing, any company that emits more than 10,000 tons of carbon a year - equal to the household and vehicle emissions of more than 400 American households - must join the offset market, which means it receives a yearly cap on its emissions and must buy carbon credits if it wants to emit more carbon. Credit prices have generally run from $55 to $75 per ton, and the penalty for exceeding the limit can cost three-to-five times the usual credit price. Around 550 companies in Beijing now take part in the exchange.
Other markets use different methods to set emission targets and determine who has to participate. Five of the seven markets give away carbon credits every year and then let companies auction off their excess credits. Hubei is the country's biggest market by volume of carbon traded.
For state-owned firms such the Chinese capital's largest power utility, Beijing's pilot market has forced business plans to factor in carbon emissions, said Jeremy Guo, executive vice president of the utility's energy investment arm. One result is a higher investment in renewable energy such as solar and the capture and reuse of heat emitted during some industrial processes, he said.
"We want to make our role of carbon asset management a new standard for the group company, not just to buy and sell to get some profit," Guo said.
What comes next year will depend on how the seven pilot markets shape up. They could link up so that a company in Beijing in the north could trade with another in the southern Chinese city of Shenzhen. Chen said another idea would be to create separate offset markets around specific industries such as steel, cement energy or construction rather than connect the separate pilots operating according to different rules.
Antung Anthony Liu, an economics professor at the Cheung Kong Graduate School of Business in Beijing, said that if done right, the markets could turn China's epic climate change fight into an international investment opportunity.
"China goes through a process where it tries to experiment with a policy before rolling it out," Liu said. "To my mind, the markets haven't the intended hopeful effect yet but capacity has been built. These markets clearly exist. And hopefully one of them will be chosen as the best one and the nation will go forward from that."

Australia Suffers Worst Drought In Years

California Turns To Australia For Drought Advice. California has turned to the world's driest inhabited continent for solutions to its longest and sharpest drought on record.
Australia, the land poet Dorothea Mackellar dubbed "a sunburnt country," suffered a torturous drought from the late 1990s through 2012. Now Californians are facing their own "Big Dry," and looking Down Under to see how they coped.
Australia also faced tough water restrictions - along with dying cattle, barren fields and monstrous wildfires that killed 173 people. But when the rains finally returned, Australians had fundamentally changed how they handle this precious resource. They treat water as a commodity to be conserved and traded, and carefully measure what's available and how it's being used. Efficiency programs cut their average daily use to 55 gallons, compared with 105 gallons per day for each Californian.
The lesson: long droughts are here to stay, so societies had better plan ahead, says drought-policy expert Linda Botterill of the University of Canberra.
"We can expect longer, deeper and more severe droughts in <a href="https://www.bing.com/search?q=australia&amp;cvid=b4f49c6152f94343a889ea69459bac08&amp;FORM=ANAB01&amp;PC=HCTS">Australia</a>, and I believe the same applies in the U.S.," Botterill says. "As a result, we need to develop strategies that are not knee-jerk responses, but that are planned risk-management strategies."
California water officials now routinely cite Australia's experience. Felicia Marcus, who runs California's Water Resources Control Board, can describe the stormwater-capture system watering soccer fields in Perth in minute detail.
But Californians may find Australia's medicine tough to swallow.
Australians are accustomed to living in a dry land, expect government intervention in a crisis and largely support making sacrifices for the common good. For much of their history, many Californians have enjoyed abundant water, or were able to divert enough of it to turn deserts green, and lawyers make sure property rights remain paramount.
From an Australian perspective, California's drought response has been "absolutely pathetic," says Daniel Connell, an environmental policy expert at The Australian National University.
Australia's drought response was hardly perfect, and some of its gains might be slipping away, but Americans suffering their own "Big Dry" may benefit from some comparisons:
---
WHOSE WATER IS IT?
AUSTRALIA: Overuse and drought had depleted Australia's main river system, which winds across four states that produce a third of the nation's food, and ran so low by 2002 that the Murray River had to be dredged to reach the sea. The government capped entitlements, canceled inactive licenses, bought back hundreds of billions of gallons from irrigators and strictly metered usage to make sure license holders use only their allocation. Availability now affects price as shares are traded on an open market worth $1.2 billion a year in U.S. dollars. California Turns To Australia For Drought Advice
The water that farms, industries and towns get depends on what's in the river; in drought, it can dwindle to virtually nothing. But entitlements can be bought and sold, keeping agriculture afloat. A farmer of a thirsty crop like cotton might not profit when both water and cotton prices are low. But if an orchard grower in desperate need buys that water, the <a href="http://www.earth.com/news/china-cotton-seeds-moon/">cotton</a> farmer can live off the sale while the orchard owner reaps a profitable harvest.
CALIFORNIA: Nearly 4,000 so-called senior water rights holders who staked claims before 1914 or own acreage abutting a river or stream get priority. In drought, authorities must completely deny water to most other claimants before they touch the water of these senior water-rights holders. San Francisco has stronger water rights than many other cities because in 1902, Mayor James Phelan hiked up the Sierra Nevada and tacked a water claim to an oak tree along the bank of the Tuolumne River. Gov. Jerry Brown calls the system "somewhat archaic."
"Revising the water-rights system is a thermo-nuclear issue in California," said John Laird, California's secretary for natural resources, but if water shortages go on, "almost everything has to be on the table."
---
WATCHING THE FLOW
AUSTRALIA: Thousands of gauges across Australia measure rainfall, authorities in each state and territory measure surface water at stream gauging stations, and underground water is monitored through a complex process involving the drilling of bores and controlled pumping tests. Water data collection agencies report to the federal Bureau of Meteorology, which publishes the data online.
CALIFORNIA: The legislature last year required monitoring to be phased in gradually, eventually showing for the first time how much groundwater is being pumped. But roughly a quarter-million California households and businesses still lack water meters, and aren't required to until 2025. The state relies on an honor system: Rights holders self-report their use of river and stream water every three years. Gov. Brown's budget proposed last week would require monitors and annual usage reports.
---
TIGHTENING THE TAP
AUSTRALIA: All major cities imposed limits or bans on watering lawns and washing cars, and inspectors fined rule-breakers. Public-service campaigns and water-saving appliances also reduced household water use from 85 gallons per person per day in 2000 to 55 gallons per person today.
CALIFORNIA: After voluntary cutbacks were ignored, Brown's administration mandated a statewide 25 percent cut in water use by cities and towns, and ordered more farmers to stop pumping from rivers and streams. Marcus said the one piece of advice that seemed universal in both Australia and California "was conserve, conserve, conserve, as early as you can, because it's the cheapest, most economical way to buy time" while tougher water-saving measures are phased in.
---
DO MORE WITH LESS
AUSTRALIA: Australians began conserving long before their drought. In 1995, Sydney's water authority was ordered to slash per-capita demand by 35 percent by 2011, and it met that target by reducing pressure and leaks in pipes, boosting businesses' water efficiency, and offering low-cost, water-saving technologies in homes, such as dual-flush toilets, low-flow showerheads and rainwater tanks for gardens, toilets and laundry. With government rebates, these devices became common across Australia.
Such efficiency measures can be implemented quickly, economically and easily, says Stuart White, an Australian sustainability expert who has advised Californians on drought response. "In some cities, it's quite possible we would have reached death's door if it hadn't been in place."
CALIFORNIA: Communities across California offer rebates on drought-friendly plumbing and appliances, and a growing number of local ordinances are being rewritten to allow families to recycle water from rains and from showers. But the rooftop-rain collectors, stormwater cisterns and bathwater-recycling for gardens common in Australia remain rarities.
---
MIRACLES OF TECHNOLOGY
AUSTRALIA: Billions were spent on desalination plants in major cities, and many are not operating because cheaper water is now available in Australia, prompting critics to dismiss them as expensive and power-hungry flops that will create greenhouse gases and worsen the continent's climate-change woes. Supporters say the plants will protect the country from the next inevitable drought.
CALIFORNIA: Brown has called for conservation while focusing on an ambitious, $17 billion plan, opposed by environmental groups, to build 39 miles of tunnel to take Northern California water to Southern California's bigger farmers. Desalination plants also are envisioned: San Diego's would be the biggest in the Western Hemisphere.

Hawaii Groups Plant Coconut Trees To Protest Monsanto. Groups Plant Coconut Trees To Protest Monsanto Demonstrators planted coconut trees and waved signs in rallies across the Hawaiian Islands as part of an international day of protests against agriculture business Monsanto.

The protesters on Saturday complained about the effects that companies like Monsanto have on the community when they spray fields with chemical pesticides. They say they want agribusiness companies to stop using Hawaii as a testing ground for pesticides and genetically modified foods.

“Get off the island,” said Diane Marshall, a <a href="http://www.earth.com/news/honolulu-faces-a-high-flooding-risk-from-multiple-sources/">Honolulu</a> teacher. “I would like to see them close up shop.”

In Waikiki, a man wore a gas mask in front of a statue of surfer Duke Kahanamoku to demonstrate the dangers of pesticides. Others in bikinis talked with tourists about why they don’t want genetically modified goods to be grown in Hawaii. Hawaii Groups Plant Coconut Trees To Protest Monsanto

“What’s cool about doing it in Waikiki with the tourists is it’s kind of giving them a light on what the issues are in Hawaii — that it’s more than just paradise,” said Nathaniel Whittaker, 28, of Honolulu.

On Maui, a group spent the day sowing fields with crops to encourage local farming. An estimated 200 demonstrators planted 2 acres of sweet potatoes, banana starts and more than 100 coconut trees, said Courtney Bruch of GMO Free Maui.

“We know that we have the power in our hands to become self-sustainable, growing our own healthy food,” Bruch said.

The Maui group was joined by Neil Young, who performed a song from his upcoming album called “The Monsanto Years,” Bruch said.

“It’s pretty amazing he came out to this farm for this event,” Bruch said.

Pake Salmon lives on Oahu but flew to Maui to take part in the planting event.

“We have all these chemical companies poisoning the land, poisoning the reef and the sea and the fishes,” Bruch said.

There has been little scientific evidence showing that foods grown from GMO seeds are less safe than their conventional counterparts, but fears persist in Hawaii and elsewhere.

An Italian scientist’s review of 10 years of research, published in 2013, concluded that the scientific research conducted so far has not detected “any significant hazard directly connected with the use of GM crops.”

The Center for Science in the Public Interest, a critic of food companies and artificial and unhealthy ingredients in foods, has not opposed genetically modified foods, on the basis that there’s no evidence they are harmful.

“We know that people have different points of view, and Monsanto Hawaii is committed to having an open dialogue about food and agriculture,” Monsanto spokeswoman Monica Ivey said in an email. “Safety is our top priority, and we conduct rigorous and comprehensive testing on each and every one of our products.”

Chiara Rose, Arctic Challenger

Woman Ends Protest After Hanging On Shell Tanker 4 Days. The woman who had been hanging off the anchor chain of a support ship that is part of Royal Dutch Shell’s plans to explore for oil in the Arctic <a href="https://www.bing.com/search?q=ocean&amp;cvid=f3a0d74955e142ebbfaaa90acb8ae661&amp;FORM=ANAB01&amp;PC=HCTS">Ocean</a> ended her days-long protest north of Seattle on Monday morning.

Student activist Chiara D’Angelo requested assistance getting down from her perch on the Arctic Challenger in the Bellingham harbor around 9:30 a.m. Monday, the Coast Guard said. Woman Ends Protest After Hanging On Shell Tanker 4 Days

D’Angelo was checked for hypothermia and then released, Petty Officer 3rd Class Katelyn Shearer said.

She spent the weekend attached to the ship in an environmental protest against Shell’s plans to drill for oil in the Chukchi <a href="http://www.earth.com/news/plant-based-diet-helps-protect-against-chronic-diseases/">Sea</a> off northwestern Alaska. The oil company’s proposal also has drawn large protests in Seattle, where a massive, floating drill rig is being prepared for the excursion.

A second protester, Matt Fuller, joined D’Angelo from Saturday morning until Sunday.

The Coast Guard cutter Ospry spent the weekend monitoring the activists but took no action, Shearer said.

Shell said Sunday that the illegal stunt would not delay its plans.

“We respect the rights of individuals to express their views related to our Arctic program, so long as they do so safely and lawfully,” company spokesman Curtis Smith said.

Smith said the two activists trespassed on private property, while compromising their safety and that of others. He commended the Coast Guard and local law enforcement for de-escalating the incident.

Lt. Cmdr. Justin Noggle, chief of enforcement at Coast Guard Sector Puget Sound, said Sunday that it is the agency’s duty to promote safety on the seas and in ports and to protect the First Amendment rights of people to safely and lawfully assemble on the water.

The Arctic Challenger is a converted barge that is designed to launch containment equipment in the event of a spill. Protesters have questioned its ability to be effective in the harsh Arctic climate.

Earlier this month, hundreds of activists in kayaks swarmed Elliott Bay in Seattle to protest Shell’s plans.

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."

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;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

Satellites reveal how Earth's systems are interconnected

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.
