Aging can mean many things. It can mean slowing down, feeling less sharp, or facing more health issues. But it doesn’t have to. A new study suggests that what women eat in midlife could set the stage for how well they age. 



Published in JAMA Network Open, the study from <a href="https://www.tufts.edu" target="_blank" rel="noreferrer noopener">Tufts University</a> and <a href="https://hsph.harvard.edu" target="_blank" rel="noreferrer noopener">Harvard T.H. Chan School of Public Health</a> dives into the power of carbohydrates and fiber in shaping <a href="https://www.earth.com/news/organ-aging-can-predict-diseases-decades-in-advance/" target="_blank" rel="noreferrer noopener">health</a> decades later.



<h2 class="wp-block-heading" id="h-how-carbs-affect-aging">How carbs affect aging</h2>



Not all carbs are equal. Some lift you up, while others drag you down.



“We’ve all heard that different carbohydrates can affect <a href="https://www.earth.com/news/how-old-are-you-really-new-tool-measures-aging-from-the-inside-out/" target="_blank" rel="noreferrer noopener">health</a> differently, whether for weight, energy, or blood sugar levels. But rather than just look at the immediate effects of these macronutrients, we wanted to understand what they might mean for good health 30 years later,” said lead author Andres Ardisson Korat.



The study zeroed in on 47,000 women, ages 70 to 93. The researchers looked at what these women ate over a span of three decades, starting in 1984. They tracked their intake of refined carbs, high-quality carbs, and fiber. They wanted to see who aged well - and who didn’t.



<h2 class="wp-block-heading" id="h-what-healthy-aging-looks-like">What healthy aging looks like</h2>



Living past 70 doesn’t mean you’re aging well. The researchers defined <a href="https://www.earth.com/news/curiosity-might-help-you-stay-sharp-as-you-age/" target="_blank" rel="noreferrer noopener">healthy</a> aging as reaching 70 without major chronic diseases, keeping a sharp mind, staying physically capable, and feeling good mentally. Out of 47,000 women, only 3,706 fit that bill.



What did those women have in common? A diet rich in high-quality carbs and fiber. The more they ate from whole grains, fruits, vegetables, and legumes, the better they aged.



<h2 class="wp-block-heading" id="h-high-quality-carbs-boost-aging">High-quality carbs boost aging</h2>



Eating more high-quality carbs wasn’t just good. It was transformative. Women who upped their intake of high-quality carbs by 10% had a 31% better chance of aging well. 



The same couldn’t be said for refined carbs. Sugary snacks and white bread were linked to a 13% drop in the odds of healthy <a href="https://www.earth.com/news/scientists-discover-a-protein-that-reverses-cellular-aging/" target="_blank" rel="noreferrer noopener">aging</a>. 



“Our results are consistent with other evidence linking consumption of fruits and vegetables, whole grains, and legumes with lower risks of chronic diseases, and now we see the association with physical and cognitive function outcomes,” said study senior author Qi Sun.



<h2 class="wp-block-heading" id="h-fiber-s-role-in-protecting-health">Fiber’s role in protecting health</h2>



Fiber doesn’t just keep things moving. It protects your mind. It shields your body. For every one-standard-deviation bump in fiber intake, the odds of healthy aging shot up by 17 percent.



Fruit fiber boosted odds by 14 percent. Vegetable fiber added 11 percent. Even cereal fiber, often overlooked, contributed a 7% increase.



The benefits of fiber went beyond disease prevention. Women with higher fiber intake had stronger memories, better physical function, and fewer mental health problems.



<h2 class="wp-block-heading" id="h-all-carbs-affect-aging-differently">All carbs affect aging differently</h2>



Glycemic index (GI) and glycemic load (GL) may sound like fancy terms, but they matter. Foods with a high GI hit blood sugar hard and fast. Not great for aging well.



High GL foods, on the other hand, had a surprising link to better mental health. But once the researchers factored in fiber intake, that connection weakened. The takeaway? Fiber might buffer some of the negative effects of high-GI foods.



<h2 class="wp-block-heading" id="h-replacing-refined-carbs">Replacing refined carbs</h2>



Imagine swapping out refined carbs for high-quality ones. What happens? Women who did had 8% to 16% better odds of aging well. That’s a big jump.



“Studies are starting to find an association between food choices in midlife and quality of life in later years. The more we can understand about healthy <a href="https://www.earth.com/news/human-bodies-begin-breaking-down-two-very-precise-ages/" target="_blank" rel="noreferrer noopener">aging</a>, the more science can help people live healthier for longer,” Korat said.



<h2 class="wp-block-heading" id="h-tracking-women-s-diets">Tracking women's diets</h2>



This study tracked women’s diets for over 30 years. It connected their midlife eating habits to their health in their 70s and 80s. The findings suggest that small, consistent changes matter more than drastic diets.



The researchers saw that women who ate more whole grains, fruits, and veggies over time aged better than those who filled up on white bread and sweets.



The study mostly included white, educated health professionals. Participants reported their own dietary habits, which might not be completely accurate. And after three decades, memories can get hazy.



Still, the findings were clear. Eating more high-quality carbs and fiber in midlife made a noticeable difference. It wasn’t just beneficial - it was transformative.



<h2 class="wp-block-heading" id="h-what-this-means-for-women">What this means for women</h2>



Aging well isn’t just about avoiding illness. It’s about staying mentally sharp, physically active, and feeling good. The study suggests that what women eat in their 40s and 50s can impact their health decades later.



But it’s not just about eating fewer carbs. It’s about eating the right ones. Whole grains, fruits, vegetables, and legumes gave women a better shot at aging well.



<h2 class="wp-block-heading" id="h-carbs-and-fiber-shape-aging">Carbs and fiber shape aging</h2>



The food choices women make in midlife are more than just meals. They’re investments. 



High-quality carbs and dietary fiber aren’t just good for digestion. They’re linked to lower risks of chronic diseases, sharper minds, and better physical health in old age.



Aging doesn’t have to mean decline, and it doesn’t have to mean slowing down. For the women in this study, eating well decades earlier paid off in a big way. The lesson? It’s never too early to think about the future. And it’s never too late to make better choices.



The study is published in the journal <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2834202" target="_blank" rel="noreferrer noopener">JAMA Network Open</a>.

High-quality carbs in midlife linked to healthier aging

A new study suggests that what women eat in midlife could set the stage for how well they age. Published in JAMA Network Open, the study from Tufts University and Harvard T.H.

When organic food first became “a thing,” naysayers scoffed, insisting that it was an overpriced fad that would never last. 

Retailers and <a href="https://www.earth.com/news/organic-agriculture-is-more-profitable/">organic food</a> producers are having the last laugh, as demand for organic food has soared. In fact, it’s at its highest level in over 10 years. 

This news comes courtesy of the Soil Association, which is expected to release an annual report on the organic food market that will show growth for the fourth year in a row. Although the industry was deeply impacted by the economic downturn, it appears to be bouncing back and shooting upwards. 

According to <a href="https://www.theguardian.com/">The Guardian</a>, individual stores are reporting an increase in their organic sales. Ocado, a store that specializes in grocery home delivery, reports that its organic sales have increased by 16%. In Tesco, they’ve gone up by 15% over the past year. 

“We are seeing that shoppers are increasingly looking to buy organic food but it needs to be affordable and consistently high quality all year round for it to be considered a viable option,” a spokesperson for Tesco said. “The popularity of organic food began with fruit and vegetables, but we are now seeing customers exploring areas such as grocery, fish and dairy. So you can now use organic produce for the whole meal.”

Tesco isn’t the only figure in the market who points to better price point and options as part of the reason why sales are moving on up. Adam Wakely, the managing director of Organic Farm Foods, agreed that these two factors have had a positive impact. 

“The organic food revival is gathering pace thanks to retailers offering a wider range of quality foods at more affordable prices. They continue to support the organic sector and the result is continued growth, outstripping non-organic foods,” he said.

When science meets agriculture, it’s an amazing thing. The development of genetically modified plants has given us drought-resistant wheat and pest-resistant corn. Could gene manipulation help animal breeders the same way it’s benefitted farmers? In <a href="https://www.earth.com/news/new-device-will-hunt-gmos-that-escape-into-the-environment/">biotechnology</a>, the field is known as gene editing, and researchers say that they are able to make beneficial changes to an animal’s genetics without causing unwanted changes. 

What kind of changes? Thanks to gene editing, cows that would normally need to be dehorned no longer have to go through that process. Scientists also hope that gene editing will be helpful to enhance the health and welfare of food animals.

Advancements in gene editing were made possible in part because of lessons learned from the dairy industry. Selective breeding among dairy cows has reduced greenhouse gas emissions related to that industry. Scientists accomplished this by breeding cows with improved productivity in mind. Thanks to this, despite their being a 1.6-fold increase in milk production, there are only around 9 million milk cows in the U.S. today, compared to 25.6 million in 1944.

Gene editing is accomplished through a variety of means. Van Eenennaam, a cooperative extension biotechnology specialist at the <a href="https://www.ucdavis.edu/">University of California Davis</a> explained how scientists expanded the limits of this field.

“A number of breeding methods, including artificial insemination, embryo transfer, crossbreeding and, more recently, genomic selection, have been used to achieve these improvements,” she said. “Now, genome editing promises to complement traditional breeding programs by precisely introducing desirable genetic variations into livestock breeding programs.”

Like genetically modified food, gene-edited food animals are sure to stir controversy and will possibly face regulation. 

“The resulting DNA sequence may be identical to existing, naturally-occurring DNA sequences,” Eenennaam explained. 

“The prospect that gene-edited animals would be subject to the same type of regulations that apply to an animal drug -- even though their genetic modifications might be indistinguishable from those obtained through conventional breeding -- is a concern for animal breeders who are eager to employ genome editing to complement traditional genetic improvement programs.”

It’s important to thoroughly wash any fruit and vegetables you eat. Oh – and don’t forget to peel off the tiny labels. You didn’t just eat a label, did you?

Annoying produce labels may soon be a thing of the past thanks to a new fruit-branding method. No; farmers aren’t going to heat up metal and brand them, Wild-West style. Rather, they’ll be branded with a brand new (pardon the pun) eco-friendly laser that will completely eliminate the need for those teensy, sticky labels. 

Think of it as a fruit tattoo. Each piece of fruit or <a href="http://www.earth.com/news/amazing-amphibians-eat-vegetarian/">vegetable</a> will be zapped with a laser that will imprint the product’s name, country of origin, and produce code number for the grocery store cashier to type in when customers check out. The branding devices are low-energy carbon dioxide lasers that simply remove the pigment from the outer skins of the produce. 

They first tested the technique out on sweet potatoes and avocados because stickers have a hard time staying put on their skins. In addition to this, people don’t usually eat the skins of those veggies, so they made good fodder for experimentation.

<a href="http://www.icagruppen.se/en/about-ica-gruppen/our-operations/ica-sweden/">ICA</a>, a Swedish supermarket chain, is the first store to try the new branding system out. If the program works, they’ll expand it to the 1,350 stores across Sweden.

Peter Hagg, a senior produce manager for ICA, pointed out to the <a href="http://www.dailymail.co.uk/">Daily Mail</a> that the change will help with more than convenience – it’s also incredibly eco-friendly. 

“It's a new technique, and we are searching for a smarter way of branding our products due to the fact that we think we have too much unnecessary plastic material or packaging material on our products,” he said. 

For those concerned about the branding affecting the way their guacamole tastes, Hagg says that they shouldn’t worry, as the mark doesn’t go through the skin or affect the product.

Swiss skiers aren’t pleased this winter. While some parts of the Alps are covered in gloriously soft and powdery snow, their side of the mountains remains largely bare. This is because December 2016 was the driest in history. In fact, it was the most dry since record-keeping started more than 150 years ago. Ski buffs did not have a very merry Christmas, as there was very little snow for the third year in a row. 

Unfortunately, this picture isn’t likely to change in the years to come. Researchers have published a study in the journal<a href="http://www.the-cryosphere.net"> The Cryosphere</a> suggesting that man-made <a href="http://www.earth.com/image/kamchatka-peninsula-captured/">snow</a> may be the key to ski resort survival in the future. 

The discouraging news comes from those who know snow best: scientists with the Institute for Snow and Avalanche Research (SLF) and the<a href="http://cryos.epfl.ch"> Cryos Laboratory École Polytechnique Fédérale</a> in Switzerland. They predict that a whopping 70% of the snow cover on the Alps could disappear within the next 100 years.

They also predict that the Alpine winter season will become shorter. This means less time for people to ski, snowboard, and snowmobile their way through the beautiful Alps. In fact, if current trends continue, the season could start anywhere from half a month to an entire month later than it currently does. 

Some of this disaster may possibly be averted, however, if humans can maintain global temperatures and ensure that they don’t rise beyond 2°C. In that case, the snow cover reduction could be limited to 30% by 2100. 

"The Alpine snow cover will recede anyway, but our future emissions control by how much,” explained Christoph Marty, the lead author of the study. 

“The majority of the climate models used project slightly increasing winter precipitation towards the end of the century. However, since temperatures are clearly increasing simultaneously we may experience increasing rainfall and not snow fall," Marty said. "We hope our results convincingly show that even increasing winter precipitation cannot compensate for the effect of the strongly increasing temperatures.”

Today’s pattern of <a href="http://www.earth.com/news/water-waste-converts-to-energy/">water</a> usage is one that’s largely governed by waste. People leave the tap running while they brush their teeth. For most Americans, the shower isn’t simply a place to get clean; they stay under the hot water each morning until they experience a virtual rebirth and feel ready for the day. Between cooking, drinking, cleaning, and bathing – it takes a lot to keep our water cycle running every day. 

This is particularly true in urban areas, home to 80% of the U.S. population. The need for energy, agricultural products, and clean drinking water keeps growing as populations continue to rise. Because of this, scientists are working to figure out how we can make better use of our urban water supply. 

Engineers with the<a href="https://www.nsf.gov"> National Science Foundation</a> have created a fascinating design – an illustration of what they’re calling the urban water cycle "of our dreams.” They believe that systems like this could make an efficient engineered water cycle a reality. 

The process involves purification using membranes that would filter water removed from lakes, rivers, and reservoirs. This could be used as drinking water.

Another source of drinking water would be desalinated water. The ocean is a huge body of water – why not use it to quench our thirsts?

Healthy crops also need clean, desalinated water, so proper irrigation would also play a part in the system. The water for irrigation would need to be monitored for contaminants, high salt levels, or anything that may disrupt crop production. 

Treatment of wastewater provides another eco-friendly potential. We know it sounds gross, but it really is possible to remove microbes and recycle wastewater for water, as well as clean energy. 

The engineers also include aquaponics in the picture. This combines acquacultue (raising fish) with hydroponics (raising plants in soil-free conditions). 

Reuse of materials like greywater and biosolids top off the water cycle utopia imagined by the team. Greywater from baths, sinks, and washing machines could be reused for flushing toilets and irrigating lawns. Meanwhile, solid waste is ideal for fertilizer and creating clean energy. 

This vision could change the way we interact with our water, treating it like the precious commodity it truly is.

<a href="https://www.earth.com/news/dakota-access-easement/">Engineers</a> from all walks of life and all over the world will get to tell their stories in the new documentary<a href="http://macgillivrayfreeman.com/project/dream-big/"> Dream Big: Engineering Our World</a>, opening February 17 at the<a href="http://www.ontariosciencecentre.ca"> Ontario Science Center</a>.  A celebration of the power of young people, key figures in the film include three young women engineers, as well as a high school engineering team. 

Viewers will experience engineering wonders such as a bridge that reaches high above the clouds, as well as powerful machines that bore huge tunnels. They’ll learn about the ingenuity behind designing the world’s tallest building, as well as the expertise needed to create underwater robots. 

The film will be narrated by Academy Award-winning actor Jeff Bridges. The actor obtained cult icon status for his role as The Dude in 1998’s The Big Lebowski and on an Academy Award for his leading role in Crazy Heart. He was also awarded a Golden Globe after appearing in Hell or High Water. 

“I am a believer in encouraging our youth to make a difference in the world, and Dream Big encourages young people to do just that,” Bridges said.

Dream Big was directed by Greg MacGillivray and produced by Freeman Films in partnership with the<a href="http://www.asce.org"> American Society of Civil Engineers</a> (ASCE). 

“As an innovator in his own field, Jeff Bridges brings his passion and inspiration to a film that encourages young people to think about engineering as a meaningful way to help others and leave a positive mark on the world,” said MacGillivray. “Teachers and parents are looking for ways to turn kids on to science and engineering, and with Dream Big we hope to bring something new to that effort with an entertaining, visually spectacular film full of stirring human stories.”

The film is presented by Bechtel working in partnership with the ASCE Foundation, the<a href="http://ncees.org/"> National Council of Examiners for Engineering and Surveying</a> (NCEES), the<a href="https://www.uefoundation.org/"> United Engineering Foundation</a> (UEF), as well as other engineering organizations.

Getting a real, live person on the telephone line may be even harder if officials and businesses take the advice of a new report from a non-party think tank. The group poses the question: could robots replace hundreds of thousands of human jobs? 

The report, published by Reform, suggests that in order to save money, employers in the UK could cut almost 250,000 human workers and replace them with computers and robots. This will also increase efficiency. 

What would the actual numbers look like if robots replace jobs in bulk? As many as 130,000 government administrators who work in Whitehall would be sent packing. This amounts to nearly 90% of administrative staff employed in the offices there, and would save £2.6 billion each year. 

In addition to this, 90,000 NHS administrative posts, as well as 24,000 GP receptionists would be affected. Automating those roles would save over £1.7 billion.

Administrative staff aren’t the only ones who would see cuts. Nursing tasks such as giving intravenous medication and collecting patient information could also be robotized. Machines are also capable of filling in for doctors, as they are more effective than humans at things like diagnosing lung cancer. 

Another reason for doctors to be nervous? Robots are better at performing routine surgical procedures. 

There could also be an increased use of robots in security and police arenas, as machines can be used to monitor suspicious activity in crowds. Facial recognition <a href="http://www.earth.com/news/green-technologies-development/">technology</a> can also be used to identify known criminals or terrorists. 

Alexander Hitchcock, a co-author of the report, said, “Such a rapid advance in the use of technology may seem controversial, and any job losses must be handled sensitively. But the result would be public services that are better, safer, smarter and more affordable.”

The report suggest that those who work in the public sector could move to a gig-based, flexible jobs for which they are hired via websites and apps in the vein of Uber.

Eco-conscious car owners are buzzing about this bit of news: <a href="https://www.tesla.com">Tesla</a> is set to begin test builds on its $35,000 Model 3 sedan on February 20th. 

Tesla Chief Executive Elon Musk announced that Tesla will shut down the production line at its California assembly plant for one week this month. That will give the team time to prepare for production of the Model 3. During the shutdown, the plant will add capacity to its existing paint shop and do maintenance necessary to get ready to crank out the much-awaited new vehicles. 

Tesla hopes to start production of the new sedan in July. Over 370,000 customers have put down deposits for the Model 3.

“This will allow Tesla to begin Model 3 production later this year as planned and enable us to start the ramp towards 500,000 vehicles annually in 2018,” a Tesla spokesperson said of the plant shutdown. 

Musk said that the final design of the Model 3 production facility will resemble an “alien dreadnought.” It will be stunning, he said – “the machine that makes the machine.” 

“You can't have people in the production line itself, otherwise you drop to people speed,” he said. “So there will be no people in production process itself.”

People will still work in the factory, Musk said, in order to maintain, upgrade, and repair the machines. 

While <a href="http://www.earth.com/news/renewable-fuel-cars-hawaii/">electric cars</a> have traditionally cost more than their gas-guzzling counterparts, the move will help turn the dream of truly affordable electric vehicles into a reality. Tesla’s 2016 Model S retailed at $68,000. The Model 3 will cut that price nearly in half. 

Tesla is betting that the Model 3 will take the company out of the niche luxury electric car market and turn it into a brand for the masses. It hasn’t been profitable since 2010, when it first went public.

One of the engineering wonders of the world, the Panama Canal is a 48-mile waterway that cuts across the Isthmus of Panama to connect the Atlantic and <a href="http://www.earth.com/news/noaa-federal-waters-fish-farming/">Pacific Oceans</a>. First opened in 1914, the canal has seen big changes in the world over the past century. 

One of those changes – an increasing size in cargo ships, was the reason behind a canal expansion that began last year. 

Lately, though, the expansion has hit some snags. Specifically, large cargo vessels traveling through the canal are hitting snags. They’re scraping up against the walls and experiencing nail-biting near-misses when steel lock doors installed throughout the systems fail to open all the way. 

That’s what happened to the cargo ship Ever Living when it traveled through the canal while carrying more than 6,000 cargo containers. Although the ship made it through, they passed extremely close to the side of the locks as they made their way through the last of the steel doors.

It was too close, according to Mauricio Perez, a tugboat captain. 

These are things that shouldn't happen," he said to the <a href="https://www.ap.org/en-us/">Associated Press</a>. "Sometimes the only thing we can do is pray."

The AP took its own journey through the updated canal and noted areas where the black rubber bumpers meant to keep ships from colliding with metal locks were worn or missing entirely. Because maneuvering large ships through the canal is incredibly difficult, sometimes captains must purposefully send a ship into a bumper in order to realign the vessel as it moves forward. This results in a huge amount of wear and tear on the protective cushions. 

Only 15 incidents occurred between June 2016 and January of this year, the Panama Canal Authority says. They say that the door lock incident was caused by debris collecting on a water-level sensor and that the problem has been resolved.

The authority isn’t ruling out future changes. Currently, though, the deputy administrator of the canal, Manuel Benitez, feels positive about the way personnel are navigating vessels through the treacherous canal. “The ships have not run aground; they continue their routes,” he said.

Hey! – at least there’s that.

Twenty-four family <a href="http://www.earth.com/news/lost-topsoil-farmers-switchgrass/">farmers</a> have something to crow about: they were just awarded grants from<a href="https://foodanimalconcernstrust.org"> Food Animal Concerns Trust</a> (FACT) via the organization’s<a href="http://www.fundafarmer.org"> Fund-a-Farmer Project</a>. 

FACT was founded in 1982 in order to promote humane farming practices. It advocates for the safe production of meat and dairy products and works to help consumers make good choices in the products they purchase. 

On their website, FACT says that they believe “that all farm animals should be granted adequate space, access to the outdoors, clean water and air, the opportunity to express their natural behaviors, and safe feed.”

The Fund-a-Farmer Project grew out of that mission. It awards grants and provides the opportunity for peer-to-peer farmer education around humane animal farming practices. 

FACT realizes that oftentimes, farmers want to make positive changes in the way they raise their animals, but these changes often chest money. By providing financial assistance, FACT hopes to make those changes a reality.

This year, farms in 15 different states received Fund-a-Farmer grants. Nine farms won Animal Welfare Certification grants, while 15 farms won grants for pasture improvement projects. 

This year’s grants bring FACT’s total awards to 91 grants across 27 states since the Fund-a-Farmer Project began in 2012. In that time, FACT has awarded over $57,000 in grants. 

Larissa McKenna, FACT’s Humane Farming Program Director, explained that they hope these grants will help individual farmers, as well as food consumers, in general.

“Today, an increasing number of people want to know where their food comes from, who produces it, and how it was grown," McKenna said. "Small and mid-sized sustainable farms are essential to meeting consumer demand for humanely-raised food, but often face financial challenges due to high costs associated with economies of scale. Our organization supports these farms by funding projects that improve animal welfare and also help farmers increase their profit margins.”

Cosmic rays sounds like something out of a Ziggy-Stardust-era David Bowie song, but they’re real. It also turns out that these radiation clouds that appear at high altitudes may be problematic for frequent airline travelers. 

Scientists have always known that people were exposed to some degree of radiation when they traveled by airplane. Things like cosmic rays and solar wind sometimes penetrate the magnetic field around the Earth, creating low levels of <a href="http://www.earth.com/news/fukushima-radiation-levels-high/">radiation</a> through which air passengers soar when they fly. Levels of this radiation are higher in the polar regions, and longer flights subject passengers and crew to more radiation than shorter ones. 

How much radiation are we talking, here? Experts previously estimated that it would take a flight of approximately 12.5 hours to deliver as much radiation as a chest X-ray. That’s if the flight stays in the high latitudes and isn’t zipping past the polar regions or traveling when there are solar storms.

Meanwhile, they reported that mid-latitude flights take around 25 hours and flights around the equator take 100 hours to deliver the same amount of radiation.

New research has revealed that the levels in radiation clouds may be higher than scientists once thought, however.

W. Kent Tobiska and his team from<a href="http://www.spacewx.com"> Space Environment Technologies</a> ran tests that found surges in radiation level data that spiked as high as double what they had previously expected. He believes that radiation particle belts trapped in Earth’s magnetic field may sometimes “leak” and move into the Earth’s stratosphere. Flying through these particle clouds could cause the kinds of spikes seen in the research. 

If Tobiska’s theory is confirmed, scientists will need to find a way to identify the location of such clouds so that air crews can avoid them during flights. The team’s findings were published in the journal <a href="http://agupubs.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1542-7390/">Space Weather</a>.

Tired of the daily traffic jam? Sick of sitting in a line of parked-and-running cars that are going nowhere fast? Elon Musk has a solution – why not just tunnel under it all? 

The billionaire founded SpaceX with the goal of making space transportation affordable and eventually colonizing Mars. He was also key in getting Paypal off the ground, as well as the architect of the <a href="http://www.earth.com/video/faraday-future/">Tesla</a> electric car. So when Musk says he’s going to do something, the world perks up its ears. 

That’s exactly what happened when Elon Musk tweeted about his frustration with Los Angeles-area traffic and what he planned to do about it. “Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging…” he wrote. 

Most people probably wrote off Musk’s tweet as someone blowing off steam. Until, that is, the next tweet arrived. This one was a picture of some sort of tunnel boring machine. This photo had the caption “Minecraft.” For those who are unfamiliar, players of the popular Minecraft game must dig huge tunnels in order to gain access to resources.

Musk knows all about travel. In addition to his groundbreaking work with Tesla and SpaceX, he’s been working to develop Hyperloop, a method of transportation in which passengers would be sealed in a pod and shot through a vacuum tube at speeds of 745 miles per hour.

Will Musk actually make good on his comments or was he simply venting in 140 characters or less? His final tweet on the matter: “I am actually going to do this.”

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">

</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."

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.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.

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."

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.

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."
