Can farms produce enough food to feed us while still leaving space for wildlife? A new proposal says they can.



By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables.



<h2 class="wp-block-heading" id="h-farming-with-wildlife-in-mind">Farming with wildlife in mind</h2>



The plan comes from ecologists at the <a href="https://www.ceh.ac.uk/">UK Centre for Ecology &amp; Hydrology</a> and the University of Alcalá in Spain. Study co-author Professor James Bullock elaborated on the importance of the research.



“Reversing <a href="https://www.earth.com/news/un-report-calls-for-global-change-to-stop-biodiversity-loss/">biodiversity loss</a> and degradation of ecosystems is essential both for nature as well as long-term global food security. But there is no single silver bullet for nature recovery and so far it has been unclear how to integrate rewilding into agricultural landscapes," said Professor Bullock. 



“Our proposed approach moves beyond land sparing versus land sharing. We believe rewilding can be interwoven into agricultural landscapes and could be key to maintaining <a href="https://www.earth.com/news/increasing-plant-based-food-production-would-have-extremely-positive-impact/">food production</a> in a way that is sustainable in the long term for people and the planet.”



<h2 class="wp-block-heading" id="h-dedicating-land-to-nature-recovery">Dedicating land to nature recovery</h2>



According to the study, fostering rewilding approaches alongside farming could create agroecological landscapes that accommodate biodiversity while remaining resilient and functionally connected. Certain incentives would encourage farmers to adopt this approach.



“While setting aside land for nature recovery could potentially be made a legal requirement for farmers and landowners, there is more likely to be acceptance and success of rewilding if there are incentives in the form of payments for ecosystem services and tax deductions,” noted Professor José María Rey Benayas, lead author on the study.



<h2 class="wp-block-heading" id="h-why-farming-needs-wildlife">Why farming needs wildlife</h2>



Modern farming has greatly increased food production since the 1940s. But this has often come at the expense of nature. 



Clearing land, using heavy fertilizers and pesticides, and removing natural features like hedgerows have pushed many plant and animal species to the edge.



This loss doesn’t just affect wildlife - it disrupts vital services that farms depend on, such as healthy soil, natural pest control, and water retention. As these services decline, the long-term productivity and resilience of farming systems are put at risk.



<h2 class="wp-block-heading" id="h-the-cost-of-declining-wildlife">The cost of declining wildlife</h2>



Across Europe and beyond, once-common species are disappearing from farmland. For example, the U.K. has lost over 40 million birds since 1970, and wild bee populations have declined in more than half of European countries, according to multiple long-term surveys.



These animals aren’t just part of the scenery - they’re key to food production. Birds eat crop pests. Bees and other insects pollinate the flowers that develop into fruits and vegetables. Their loss means greater reliance on artificial fertilisers, pesticides, and expensive manual labour.



Bringing wildlife back isn’t just a conservation goal - it’s a practical step toward more affordable and reliable <a href="https://www.earth.com/news/mixed-cover-crops-may-be-the-future-of-sustainable-farming/">farming</a>.



<h2 class="wp-block-heading" id="h-steps-to-farming-alongside-wildlife">Steps to farming alongside wildlife </h2>



The researchers suggest a four-part plan that links nature conservation with everyday farming. 



First, they recommend reserving at least 20% of farmland for nature. This space would include large patches of woodland, wetlands, and species-rich grassland to form strong core habitats. 



Second, these patches should be connected by green corridors - such as hedgerows, ponds, and strips of scrubland - that allow wildlife to move, feed, and reproduce.



Third, they propose protecting small hotspots within working fields. This would involve setting aside about 10% of cropped land for flower strips, beetle banks, and bird perches, bringing the total to the 30% global restoration goal. 



Finally, they call for small changes in daily farming practices, like reducing chemical use, planting flowers for <a href="https://www.earth.com/news/pollinators-face-extinction-risk-due-to-climate-change/">pollinators</a>, and letting livestock graze more freely to help spread seeds and support healthy soil.



<h2 class="wp-block-heading" id="h-rewilding-has-benefits-for-farmers">Rewilding has benefits for farmers</h2>



Many European regions cannot host bears or bison. However, smaller species such as lynx, wildcat, or European hare can still boost ecosystem health. Choosing the right mix depends on local conditions.



Helping wildlife can pay off in more ways than one. When farms support natural habitats, they often see practical benefits in return. 



Better soil retains more water and nutrients, which supports stronger <a href="https://www.earth.com/news/farmers-can-help-make-crops-more-resilient/">crops</a>. Pollinators and natural predators of pests can help increase yields in nearby fields. 



Farmers may also spend less on fertilizers and pesticides, lowering overall input costs. In some places, governments might provide payments or tax breaks to reward efforts that support biodiversity and ecosystem services.



<h2 class="wp-block-heading" id="h-making-room-for-wildlife">Making room for wildlife</h2>



Reaching the 20% target may be challenging for small farms, but collective action can make it achievable. At the same time, each region will need to adapt the plan to fit its local conditions. 



Areas with heavily degraded farmland have the most to gain, while places with traditional, low-impact farming may require fewer changes. 



The researchers emphasize that this is just a starting point - but the message is clear: making room for wildlife alongside farming can help secure both indigenous species and food for the future.



The full study was published in the journal <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2860">Frontiers in Ecology and the Environment</a>.

Farming for wildlife: How traditional practices can protect nature

By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables.

Last week, <a href="https://www.earth.com/news/calculating-cost-climate-change/">we told you</a> about how much rising sea levels caused by global warming could cost major cities around the world. Now, scientists are warning that one major city in particular could be especially at risk. According to new research, rising sea levels could cause Venice to completely disappear underwater within the next 100 years.

Scientists from Italy’s <a href="http://istituto.ingv.it/the-institute/the-institute/view?set_language=en">National Institute of Geophysics and Volcanology</a> are warning that the Mediterranean Sea water levels could rise by as much as 5 feet by 2100. To put that into perspective, the Mediterranean has risen by only 1 foot in the past 1,000 years. But global warming has significantly accelerated that rate, which will put Venice, and other cities along Italy’s Adriatic coastline, in jeopardy.

The team of researchers used quarries along the Mediterranean coast to model how sea levels have changed over time. They reported in their findings in a study published in the journal <a href="https://www.journals.elsevier.com/quaternary-international/">Quaternary International</a>.

“The coast of the Mediterranean provides several remnants of ancient coastal quarries, which are now useful to study sea level change occurring during the last millennia,” the team said in the paper. “Millstones quarries were exploited with same quarrying techniques from rocks like beach rocks, sandstones or similar lithologies, were shaped to be suitable to grind olives, seeds and wheat, to produce oil and flour, or to break apart soft rocks.”

The team used these coastline quarries to understand how sea levels have changed over the last 1,000 years, and then were able to model how they may change in the future. They found that 33 regions across the coast of Italy are at high risk of being completely submerged underwater. 

The list includes the Versilia in Tuscany, Fiumicino in Lazio, coastal areas around Catania, Oristano, and Cagliari, and land around the Po, Fondi, Sele, and Volturno rivers.

During his 2016 presidential campaign, Donald Trump promised on many occasions to walk away from the landmark <a href="http://unfccc.int/paris_agreement/items/9485.php">Paris Agreement</a>, a treaty signed by 194 nations in an effort to curb <a href="https://www.earth.com/news/forests-reduce-greenhouse-gases/">greenhouse gas</a> emissions and climate change. In a campaign <a href="http://mashable.com/2016/11/22/trump-climate-paris-agreement-nyt-interview/#jc8aEY9yWaq6">speech</a> in May 2016, Trump promised, “we’re going to cancel the Paris Climate Agreement and stop all payment of U.S. tax dollars to U.N. global warming programs." Now, the <a href="https://www.nytimes.com/2017/03/02/us/politics/climate-change-trump.html?smprod=nytcore-ipad&amp;smid=nytcore-ipad-share&amp;_r=0">New York Times</a> is reporting that Trump’s key advisors are heavily divided on how the administration will proceed with the Paris Agreement.

In one corner is Trump senior advisor Steve Bannon, who sources say firmly believes that the United States should fully withdraw from the treaty. Bannon is the former head of Breitbart News, which has regularly run editorial pieces calling climate change a complete hoax. 

In the other corner are Ivanka Trump and Secretary of State Rex Tillerson, who believe that there could be significant diplomatic fallout from allies should the United States completely pull out. While Trump could not single-handedly dismantle the Paris Agreement, he could begin a 4-year process for U.S. withdrawal, which in turn, could damage the nation’s credibility abroad. While Ivanka Trump has yet to publicly speak out on the matter, she has met with high-profile environmental activists like Al Gore and Leonardo DiCaprio.

The <a href="https://www.wsj.com/articles/ivanka-trump-jared-kushner-pushed-to-remove-language-critical-of-climate-deal-from-executive-order-1487889272">Wall Street Journal</a> has also reported that Ivanka Trump has quietly represented environmental interests in the oval office. A February 23rd WSJ piece wrote, "At the request of President Donald Trump's son-in-law, Jared Kushner, and his wife, Ivanka Trump, language critical of a global climate deal was struck from an executive order that Mr. Trump is planning to sign soon, according to multiple people familiar with the move."

As <a href="https://www.earth.com/news/trumps-budget-epa-programs/">we reported</a> this week, sources say Trump’s new <a href="https://www.epa.gov/">EPA</a> budget could cut the department’s funding by 24% and slash a significant number of environmental programs.

The Irish Potato Famine, which starved millions and brought many desperate immigrants to America, is now safely behind us. Or at least late blight, the disease that wiped out the Irish potato crop of 1846, won’t threaten three genetically engineered varieties of potato that won recent regulatory approval.

The Russet Burbank, Ranger Russet and the Atlantic, all genetically engineered against late blight by Idaho-based J.R. Simplot Company, won approval by the <a href="https://www.fda.gov/">FDA</a> and the U.S. <a href="https://www.epa.gov/">EPA</a> last week, after already getting the nod of the <a href="https://www.usda.gov/">U.S. Department of Agriculture</a>.

Simplot spokesperson Doug Cole said that the new varieties "have the same taste and texture and nutritional qualities” of unmodified potatoes.

The three are said to only carry potatoes genes, including the genes of an Argentine potato variety with a natural defense against late blight – a potato pathogen that even today threatens crops, especially in wetter environments.

In addition, these three new <a href="https://www.earth.com/news/new-genetically-engineered-potatoes-approved/">potatoes</a> were genetically modified to reduce bruising and black spots in storage and to contain less of a potentially carcinogenic chemical that’s created when potatoes are cooked at high temperatures. The enhanced storage capabilities will also prove beneficial to the potato chip industry in reduced trucking costs, said the company.

Genetically modified organisms – or GMO – is a controversial practice. Many people refuse to buy or eat GMO products, and food companies such as McDonald’s have refused to use GMO potatoes for their French fries.

With the federal regulatory approval, J.R. Simplot Company can now offer their three new potatoes for planting this spring and harvesting in the fall.

This is the company’s second generation of GMO-approved products. The first, which is in stores, offered no protection against late blight. J.R. Simplot is now working on a third generation of modified potatoes.

Ever since President Donald Trump appointed Scott Pruitt to run the <a href="https://www.epa.gov/">Environmental Protection Agency</a> (EPA), an organization he notoriously fought against for years, environmental activists have braced for massive cuts in EPA programs. Now, <a href="http://www.cnn.com/2017/03/02/politics/epa-programs-donald-trump-budget/index.html">CNN</a> is reporting that a source has revealed exactly which EPA programs are on the chopping block under Trump’s budget proposal.

The source told CNN that the latest proposal would slash the EPA budget by 24% and cut staff by 20%. Specific programs facing possible elimination include initiatives intended to improve <a href="https://www.earth.com/video/houseplants-reduce-indoor-air-pollution/">air</a> and water quality, along with regulations to reduce greenhouse gas emissions. 

The Environmental Justice Program, which was established to help local communities with environmental issues, faces possible elimination.

The Clean Power Plan, an initiative set up by former President Barack Obama intended to reduce carbon emissions in each state, could also be cut. The list also includes 14 other EPA partnership programs aimed at reducing greenhouse gas emissions, along with the Diesel Emissions Reduction Act.

A number of grants and fellowships also face elimination, including Energy Star grants and Science to Achieve Results (STAR) graduate fellowships.

"The Trump administration has decided fence-line communities across the country, whose residents already bear an outsized burden from pollution, are on their own to take on big polluters,” Ken Cook, head of the Environmental Working Group, told CNN. 

The possible elimination of the Environmental Justice Program, in particular, has many outraged. The program focuses on equal and fair protection from environmental hazards for people of races. 

"To cut the Environmental Justice program at EPA is just racist," John Coequyt, campaign director the environmental group Sierra Club, told CNN. "I can't imagine it's an office that runs up much cost. I can't describe it in any other terms than a move to leave those communities behind. I can't imagine what the justification would be, other than racism."

Scientists have announced a major breakthrough in the search for life on other planets. A new study reports that researchers have found traces of bacteria that lived 3.7 billion years ago, making them the oldest <a href="https://www.earth.com/news/fossils-mass-extinction-event/">fossils</a> ever discovered. While final verification is still pending, the discovery could support the theory that life started soon after the planet formed, which means that could have been the case on other planets as well.

A collaborative team of researchers say that the fossilized bacteria lived around hydrothermal vents on the ocean floor. Scientists can use this information to search vents on other planets for signs of life. 

The researchers reported their findings in a report published in the journal <a href="http://www.nature.com/nature/index.html">Nature</a>.

“It’s exciting to find life had managed to get a grip and start to evolve on Earth so quickly after the planets formed,” said co-author Matthew Dodd of Britain’s <a href="http://www.ucl.ac.uk/">University College London</a>. “It gives me … high hopes of finding life elsewhere in the universe.”

Dodd was inspecting pieces of rock found in northern Quebec when he noticed an unusual feature. The rock contained thread-like filaments half the width of human hair and thicker cylindrical tubes both consisting of iron-rich mineral. Such filaments are known to be produced by bacteria that eats iron.

Additional formations on the rock led scientists to believe that the bacteria lived around hydrothermal vents on the ocean floor and fed on the iron-rich water that gushed through. 

Dodd argues that such a finding raises the possibility that life occurred on Jupiter’s moon Europa, which holds a considerable amount of water. 

“You have life on Earth at a time when we believe there was liquid water on the surface of Mars, and the atmosphere wouldn’t have been too drastically different,” Dodd added. “Maybe there was life on Mars in the past and we have yet to find it.”

Is the burning of <a href="https://www.earth.com/news/forest-biomass-processing-plants-too-expensive/">biomass</a> for energy really always more environment-friendly than the use of fossil fuels for electricity generation and heat? That’s the position that’s been put forth by advocates of wood-burning, and it’s challenged in a research paper released February 23 and titled,<a href="https://www.chathamhouse.org/sites/files/chathamhouse/publications/research/2017-02-23-woody-biomass-global-climate-brack-embargoed.pdf"> Woody Biomass for Power and Heat, Impacts on the Global Climate</a>.  The paper’s author, Duncan Brack, is an independent environmental policy analyst, an associate fellow of Chatham House and an associate of Green Alliance.

He writes, “Although there are alternatives to the use of wood for biomass power and heat, including organic waste, agricultural residues and energy crops, they tend to be less energy-dense, more expensive and more difficult to collect and transport.”

Brack challenges the widely accepted perception that woody biomass is a carbon-neutral source of renewable energy, with benefits to forest growth and the global climate. The carbon-neutral argument relies on the fact that strategic harvesting of wood positively impacts forest growth, which counterbalances the carbon emissions of wood burning.

“In fact,” he writes, “since in general woody biomass is less energy dense than fossil fuels, and contains higher quantities of moisture and less hydrogen, at the point of combustion burning wood for energy usually emits more greenhouse gases per unit of energy produced than fossil fuels.”

Brack feels that biomass plants tend to operate less efficiently than fossil fuel plants, releasing more carbon emissions into the atmosphere.  He has issues with the supply-chain emissions from the harvesting, collecting, processing and transport of wood and with methane emissions derived from wood storage. He also challenges real-world practices related to forest growth.

He concludes, in part, “The use of woody biomass for <a href="https://www.earth.com/news/water-waste-converts-to-energy/">energy</a> cannot be considered to be automatically carbon-neutral under all circumstances, though most policy frameworks treat it as though it is.…In addition, where the feedstock derives from harvesting whole trees, net carbon emissions will increase from the foregone carbon sequestration that would have occurred had the trees been left growing.”

To <a href="https://www.earth.com/news/oroville-dam-californian-catastrophe/">Californians</a>, it can sometimes seem like their state is in drought or high water. On Wednesday, one of the wettest seasons on record brought a flood that displaced thousands of homeowners in and around San Jose. Among the 50,000 who were warned to leave, the order was mandatory for 14,000 of the most threatened residents.

The crisis occurred when Silicon Valley’s Coyote Creek flooded its banks late Tuesday and early Wednesday after heavy rainfall.

The region’s water agencies and rescuers were taken by surprise. Although emergency alerts had been sent out to those who’d signed up for alerts, some residents reported knowing nothing about the evacuation order until they saw first responders in dinghies.

“If the first time a resident is aware that they need to get out of their home is when they see a firefighter in a boat, that's a failure,” said San Jose Mayor Sam Liccardo. “We are assessing what happened in that failure.”

The suddenness of the flood was attributed to the “atmospheric river” weather pattern, a narrow corridor of moisture that can bring on sudden and severe weather conditions. Adding to the challenge, the floodwater is most likely to be contaminated by raw sewage.

“People should take every precaution to stay away from the water to avoid illness or injury,” warned Sara Cody, a Santa Clara County health officer.

The San Jose flood is only the latest weather calamity brought on by the state’s sustained downpours. Oroville Dam to the north has been in the news for its near-collapse when its reservoir overflowed and damaged spillways.

Although floodwaters were receding in San Jose by late Wednesday, Mayor Liccardo said residents wouldn’t be allowed to return until at least Thursday.

Mexico City is crumbling. We’re talking more than typical city terms of a crumbling infrastructure – the city itself is actually collapsing and sinking into the earth. 

How can this be happening? Mexico City sits on a base of clay – the same clay on which the Aztecs built the first structures of the city. That clay is weakening fast as the city drills into it in a desperate quest for water. 

The <a href="https://www.earth.com/news/urban-water-cycle-dreams/">water</a> shortage has become an increasing crisis in Mexico City. Drought and immense heat intensified by climate change is causing water stores to evaporate. This means that in neighborhoods like Iztapalapa, people never know what to expect when they turn the handle at their tap. This is the situation for almost 20% of the city’s residents. 

The more Mexico City drills for water, the faster the city sinks. In some areas, the earth is dropping at an amazing rate of nine inches per year. This is causing a multitude of problems. One of them is cracking and crumbling buildings and sidewalks. More than a cosmetic problem, it’s extremely dangerous. In one incident, a crack in a sidewalk suddenly widened and swallowed a teenager. In total, 15 elementary schools have been affected by the sinking – either crumbling or collapsing entirely. 

Another issue? As the city sinks, its wastewater is no longer properly draining into the Grand Canal. The canal was constructed to deal with tens of thousands of gallons of wastewater. However, it was designed so that gravity would drain the water from the city and pour it into the canal. With the city falling, drainage has been affected – causing a constant stench across the area. 

A government fix for the problem seems unlikely, according to Claudia Sheinbaum. Formerly an environment minister, she developed Mexico City’s first climate change program. 

“There has to be a consensus — of scientists, politicians, engineers and society — when it comes to pollution, water, climate,” Sheinbaum told the <a href="http://www.nytimes.com/">New York Times</a>. “We have the resources, but lack the political will.”

Get out your umbrellas. And your rain boots. And your kayaks? Southern California is bracing for a strong storm slated to hit the area starting Friday and continuing through Saturday. Officials say that it will bring heavy, nonstop rain and strong winds. As with most bad weather in California, it will also potentially cause flash flooding and dangerous mudslides. 

Los Angeles and Ventura Counties are expecting as much as 6 inches of nonstop rain. South-facing foothills and coastal mountain areas could receive as much as 5 to 10 inches. The <a href="https://www.earth.com/news/snow-water-deficit-california/">storm</a> will create record-breaking rainfall totals for some areas of the state. 

Some areas, such as neighborhoods in the Fish Fire burn area of the city of Duarte, have issued evacuation notices for their residents, who are increasingly nervous. 

"I'm a little anxious knowing that we have pack up the house again, twice in one year to get out of our home. We got booted out when the Fish Fire hit, the fire department did a great job and kept us super safe, all of our homes were saved," Jill Brainard said to <a href="http://ktla.com/">KTLA</a>. "But this is a little different, you can't control mudflow and rain.”

Despite the overwhelming amount of rain that’s fallen in California over the past few months, experts say that the state’s five-years-long drought isn’t quite over. This is because the rainfall has been focused on the northern half of the state. In those areas, once-low reservoirs are brimming with water once again. 

The middle and southern parts of the state, however, are still suffering from moderate to severe levels of drought. Experts say that it will take more than one rainy winter to correct the problem. 

“Luckily, they got one record setting winter this year, which is great,” <a href="http://www.noaa.gov/">NOAA</a> meteorologist David Miskus said to <a href="http://www.washingtonpost.com/">The Washington Post</a>. “But what will happen next year? You don’t know what next winter will bring.”

Scientists find a way to reuse our water waste AND make thermal <a href="http://www.earth.com/news/waste-to-energy-plants/">energy</a>. We waste gallons of water each day, every time we run the sink, do laundry, wash dishes, or take a bath or shower. That water, known as greywater, could potentially be reused, but most homes and buildings don’t have the capability of recycling it.

This is even more of a concern in places where water is a precious commodity. Recycling greywater would mean that fresh, clean water could be used for drinking and cooking, rather than lost after being used for washing.

Architect Maria Paz Gutierrez (a mentor at the<a href="http://www.berkeley.edu"> University of California, Berkeley</a>) hopes to change all of that. Working with Slav Hermanowicz, an environmental engineer, and bioengineer Luke Lee, she’s found a way to put greywater to work. It’s job? Making thermal energy.

While greywater can’t be recycled as drinking water – it’s not clean enough for that – it can be reused for things like flushing toilets and washing laundry. The system created by Gutierrez would send that greywater cycling back through the system to be used a second time, but it would also be used to make thermal energy that would lower electricity bills.

"This is the future of sustainable building systems--synergistic optimization processes that are win-win from the local to the global scales," said Gutierrez. "The end user benefits because they're using less water and paying less for electricity or gas; the community benefits because it has less water to treat; the environment benefits because we're not going to be contaminating aquifers. That's the fundamental difference between this design and other building systems.”

The team’s research was supported by the<a href="https://www.nsf.gov"> National Science Foundation</a>. While the technology is currently in its infancy, Gutierrez says it could be available for commercial purposes within 10 years. Her goal is to bring the price point down to one that would be realistic in areas where water is scarce. We are looking forward to a future where our water waste is converted into something useful.

U.S. demonstrates measured response to North Korea missile test. As <a href="http://www.earth.com/video/north-korea-pyongyang/">North Korea</a> fired a missile into the Sea of Japan early Sunday morning, President Donald Trump seemed to be making moves to de-escalate the situation. 

The missile was an intermediate-range Musudan-class missile. This style of missile has a range of between 1,550 to 2,500 miles. If fired from North Korea, a Musudan could reach South Korea and Japan at the lower end of its range. At the upper end, it could reach U.S. military bases located on Guam. 

Government officials are concerned that North Korea may be working to perfect an Intercontinental Ballistic Missile (ICBM). If they were to successfully develop ICBM technology, the missile would be capable of reaching the continental U.S. – a full 3,400 miles away from North Korea. Some ICBMs can travel as far as 6,200 miles. 

In a statement, the South Korean Office of the Joint Chiefs of Staff said, "Our assessment is that [the missile test] is part of a show of force in response to the new U.S. administration's hardline position against the North.”

When North Korean leader Kim Jong-Un announced in January that his country was nearly ready to test an ICBM, Trump responded by tweeting “It won’t happen!” His administration has not released details on what their exact policy will be on North Korea. 

Early indications are that the Trump administration will look to China to take a stand against North Korea. 

In an appearance on Fox News Sunday, White House adviser Stephen Miller said, "We are going to reinforce and strengthen our vital alliances in the Pacific region as part of our strategy to deter and prevent the increasing hostility that we've seen in recent years from the North Korean regime.”

President Trump indicated that the U.S. would be standing by Japan after holding a meeting with Shinzo Abe, that country’s prime minister. 

"I just want everybody to understand, and fully know, that the United States of America is behind Japan, our great ally, 100 percent," Trump said to reporters.

APTOPIX Damaged Dam

Evacuations ordered as officials fear Oroville Dam collapse. Twelve years ago, officials were warned that the Oroville Dam wasn’t in good shape. They rejected those concerns. Now, nearly 200,000 people have been evacuated from Butte, Sutter, and Yuba counties amid growing fears that the dam could collapse, putting neighborhoods under 100 feet of water. 

The <a href="http://www.earth.com/news/relentless-rain-california-nevada-west/">California National Guard</a> is on standby, waiting to be deployed as residents lined up to leave the area on Sunday. Traffic was bumper-to-bumper, and people were frightened and furious.

Gas station manager Raj Gill was told by his manager to evacuate, but chose to stay put and help evacuating residents gas up. 

“You can't even move,” he told the<a href="http://www.dailymail.co.uk/ushome/index.html"> Daily Mail</a>. “I'm trying to get out of here too. I'm worried about the flooding. I've seen the pictures - that's a lot of water.”

It would indeed be a lot of water. Although officials have activated an emergency spillway not put into use for almost 50 years, that may not be enough. A 170 x 250-foot hole on the concrete lip of the dam’s secondary spillway has been exacerbated by flooding from recent storms. Engineers dropped rocks into the hole in order to temporarily plug the water flow.

However, with more bad weather on the way, officials worry that the weakened area of the dam could fail entirely.

Although water is no longer pouring over the damaged area, the evacuation orders are still in place while law enforcement and engineers work to figure out the best course of action. 

At a news conference, Butte County Sheriff Kory Honea updated residents on the situation. 

“There is [sic] still a lot of unknowns,” he said. “We need to continue to lower the lake levels and we need to give the Department of Water Resources time to fully evaluate the situation so we can make the decision to whether or not it is safe to repopulate the area.”

Oroville Dam about to cause Californian catastrophe

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">
https://youtu.be/Ug657J67iEo?si=w96YjGMsg939LD_3
</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

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.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.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

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://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.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."

“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.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> some of the most incredible waves in the world, as seen by Landsat satellites.



"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."
