Extreme heat is creeping into more of our lives every year. Summers are hotter, heat waves last longer, and nights don’t cool the way they once did. Yet many older adults don’t see heat as a threat, and even fewer prepare for it in advance. 



A new review of more than 40 studies shows that this lack of awareness could have deadly consequences.



The new research analyzed 41 studies worldwide between 2010 and 2024. Most of them - 29 in total - looked at coping strategies during <a href="https://www.earth.com/news/older-adults-may-not-be-safe-from-heat-waves-even-inside-their-homes/">heat waves</a>, such as staying hydrated or moving to cooler spaces. Only one study focused on actual preparedness before extreme weather arrives.



“Extreme heat is not often viewed as a weather disaster like hurricanes or floods, but it should be,” said Professor Smitha Rao of <a href="https://www.osu.edu/" target="_blank" rel="noreferrer noopener">The Ohio State University</a>. “It is not something that is visible, which is why it is often called the ‘silent killer.’”



<h2 class="wp-block-heading" id="h-why-the-issue-matters-now">Why the issue matters now</h2>



Heat doesn’t feel the same at 75 as it does at 25. As people age, their bodies lose some ability to regulate temperature. 



Medical conditions and medications can make overheating worse, and <a href="https://www.earth.com/news/wearable-sensor-can-help-prevent-dangerous-dehydration/">dehydration</a> happens more quickly. Many older adults don’t notice the danger until it’s too late, often while at home or even during the night.



That risk is growing more urgent as older adults become one of the fastest-growing age groups. By 2050, people 65 and older will outnumber children under five. 



This demographic shift coincides with climate change bringing record-breaking heat, with 2023 and 2024 among the hottest years and temperatures still rising.



“We tend to react based on past experiences in our lives and the reality has changed,” said Professor Holly Dabelko-Schoeny. “The things that worked in the past to deal with heat waves are not going to work in this new reality.”



<h2 class="wp-block-heading" id="h-the-role-of-health-and-medications">The role of health and medications</h2>



The danger isn’t just outside. Many heat-related deaths occur in people’s own homes. Older adults and their caregivers may not realize that certain medical conditions or medications increase vulnerability. 



As bodies age, the natural ability to <a href="https://www.earth.com/news/humans-have-a-lower-heat-tolerance-than-expected/">regulate temperature</a> weakens. That means what once felt like a tolerable summer evening could now be life-threatening.



“We may not realize that our bodies’ reactions to heat changes as we age, and older adults and their caregivers may not realize that some of the medicines they are taking or medical conditions they have may make them prone to overheating,” Rao said.



<h2 class="wp-block-heading" id="h-gaps-in-service-and-policy">Gaps in service and policy</h2>



Beyond individual coping strategies, only seven studies in the review looked at how services are delivered during extreme heat. Many programs put more effort into protecting against <a href="https://www.earth.com/news/how-extreme-cold-events-fit-climate-change-model-global-warming/">extreme cold</a> than against heat, showing how unbalanced the awareness remains. 



The fewest studies explored policies to safeguard older adults, even though that could make the biggest difference.



Changes in local policies show what’s possible. In Columbus, the Central Ohio Transit Authority now makes buses free during extreme heat events. That allows anyone, young or old, to travel without cost to cooling centers.



“It is good to see policy changes like this that are responding to what our new normal looks like,” said Marisa Sheldon, director of the Age-Friendly Innovation Center at Ohio State’s College of Social Work.



<h2 class="wp-block-heading" id="h-the-role-of-relationships">The role of relationships</h2>



Preparedness isn’t only about air conditioning or public transport. Relationships matter. In a related article in the journal Environmental Communication, researchers found that older adults’ sources of information - and the trust they place in them - are key to survival.



“One compelling finding from both studies was the importance of relationship building,” said co-author Fiona Doherty, now an assistant professor of social work at the University of Tennessee. 



“Not only <a href="https://www.earth.com/news/neighbors-can-help-reduce-the-health-risks-of-living-alone/">connecting neighbors</a>, but also learning what information sources older adults trust and building trust between individuals and community agencies so that community members follow expert guidance and change their behavior when necessary.”



<h2 class="wp-block-heading" id="h-facing-the-future-of-heat">Facing the future of heat</h2>



As the world heats up, the risks for older adults grow sharper. Heat isn’t dramatic like a hurricane, but it is just as dangerous. 



Preparing homes, creating clear public policies, and building stronger community networks may save lives. 



What once worked may no longer be enough. The challenge now is to change how we think about heat - and to make sure no one is left unprepared.



The full study was published in the journal <a href="https://journals.plos.org/climate/article?id=10.1371/journal.pclm.0000689">PLOS Climate</a>.

Extreme heat is leaving older adults dangerously unprepared

Extreme heat is creeping into more of our lives every year. Summers are hotter, heat waves last longer, and nights don’t cool the way they once did. Yet many older adults don’t see heat as a threat, and even fewer prepare for it in advance. A new review of more than 40 studies shows that this lack of awareness could have deadly consequences.

The <a href="http://www.earth.com/news/pesticide-regulation-hawaiian-residents/">Hawaii</a> legislature is working to pass a bill that would put the state on the fast track to eco-conscious transportation. The hope is to have all vehicles in the state running on renewable fuel by 2045. If that seems like a huge hurdle, keep in mind that Hawaii has set a similarly high bar for its utilities, which it also hopes to see running 100% on <a href="http://www.earth.com/news/renewable-energy-capacity-overtaken-coal/">renewables</a> by 2045. 

While the state is hoping to push for the change in transportation, they’re aware of the problems this may pose to residents and aren’t making them switch out their vehicles just yet. 

"Nobody wants to step in and force people to get rid of cars that they might love now," state Rep. Chris Lee, chairman of the Energy and Environment committee, told the <a href="https://www.ap.org/en-us/">Associated Press</a>.

Beyond a potential pushback from Hawaiians who are hesitant to purchase new cars, legislators know they’re facing an automobile industry that has been slow to change. In the state of Hawaii alone, there are only around 5,000 electric vehicles among the 1 million cars traveling the roads. While the Hawaiian auto industry is supportive of the bill, big changes in a small state won’t be enough to shift the global automotive industry in an environmentally-friendly direction. 

While the current bill won’t enforce renewable fuel mandates, it will make Hawaii more friendly to electric car drivers. It will increase the required number of electric vehicle charging stations so that drivers can boost their batteries while stopping to shop or grab a bite to eat. 

Hawaii currently ranks second in the U.S. for its number of electric car owners; it has 2.94 electric vehicles for every 1,000 residents. It has also developed and pursued renewable energy strategies more aggressively than any other state.

Dogs simply love heading outside for a walk. This daily <a href="http://www.earth.com/news/the-truth-about-dog-dreams/">dog</a> walking ritual between pet and owner serves as a bonding experience – one that researchers have discovered is more complex than people originally thought.

A recent study published in <a href="http://www.tandfonline.com/toc/rscg20/current">Social &amp; Cultural Geography</a> shows that dog walks actually involve constant negotiation about where to walk, how long to walk, and how the walk will take place. Dog owners often make these decisions based on their perception of their pet’s personality, likes, and dislikes. 

Taking a dog for a walk involves more than simply heading out the door for a bit of exercise. Louis Platt, lecturer at <a href="http://www2.mmu.ac.uk">Manchester Metropolitan University</a> and co-author of the study, says that dog walking is a shared experience between the dog and owner. Humans want to see their dogs have fun and wish to provide a safe, stress-free environment in which that can happen. 

This is why dog owners tailor their walk schedule and journey to their dog’s individual needs. Many owners hit the great outdoors with their canine companions because they feel that it’s where their pets can let loose and demonstrate the “doggyness” that is so often denied to them while indoors. 

Owners spoke of heading to their dog’s “favorite park” or areas where they felt the dog enjoyed frolicking. They also customize the length of their walks according to what they felt their dog would most enjoy. One study participant said that long daily walks were part of her dog’s “right” to a good life. 

Caution and anxiety also play a role in dog owner’s decisions about where and how to walk. People with large or aggressive dogs tend to avoid paths where they might meet other dogs, lots of people, or small children. Letting their canines off leash was another activity where dog owners took special care. Many of them expressed concern at the idea of their dog wandering away. Owners who approve of off-leash dog walking feel that this is “the dog’s time” to be itself. 

From when to leash up to where to head out, there’s definitely more to dog walking than lifting legs and wagging tails.

Scientists are warning that salmon caught in the Pacific Northwest may be carrying an unwanted –and unappetizing – passenger. The Japanese broad tapeworm, previously thought to only infest fish in the Pacific waters around <a href="http://www.earth.com/news/japan-promises-climate-change-funds-to-pacific-island-nations/">Japan</a>, is now targeting fish being caught off of U.S. shores. 

Diphyllobothrium nihonkaiense, or the Japanese broad tapeworm, is a parasite. It can infect humans, but is also frequently found in other carnivores such as wolves and bears. It can grow up to 30 feet long and often causes few symptoms. If symptoms do arise, they’re often in the form of abdominal pain, nausea, diarrhea, and weight loss. In some extreme cases, can cause intestinal obstructions. Thankfully, once doctors have identified that a tapeworm is the culprit, they can effectively treat it using oral medications. 

The <a href="https://www.cdc.gov">Center for Disease Control</a> published the stomach-churning findings in the February edition of the journal, <a href="https://wwwnc.cdc.gov/eid/">Emerging Infectious Diseases</a>. The CDC said that “salmon from the American and Asian Pacific coasts and elsewhere pose potential dangers for persons who eat these fish raw."

Researchers said they wanted to warn doctors who may not typically be on the alert for symptoms of tapeworm infection.

“Because Pacific salmon are frequently exported unfrozen, on ice, plerocercoids may survive transport and cause human infections in areas where they are not endemic, such as China, Europe, New Zealand, and middle and eastern United States,” the researchers wrote.

Despite the warnings about consuming raw or undercooked salmon, American <a href="http://www.earth.com/news/sushi-tuna-population-microbeads/">sushi</a> lovers can breathe a sigh of relief. The Food and Drug Administration requires that all fish to be used for sushi must be frozen first to kill off parasites. Although people prize sushi because of the perception that the fish is fresh, it’s actually all been frozen and thawed – making it deliciously tapeworm-free.

Reopened Silk Road route swaps horses for trains. Hundreds of years ago, merchants traveled the Silk Road from <a href="http://www.earth.com/news/china-ivory-trade-ban/">China</a> to <a href="http://www.earth.com/news/european-union-celebrates-paris-agreement-climate-change/">Europe</a>, bringing silk, paper, gunpowder, and various exotic goods to trade. Today, the route is being revived with the introduction of a 7,456-mile train route from China to London. 

China’s East Wind train company is celebrating the debut of its Silk Road route that will run from Yiwu, a manufacturing town in East China, to Great Britain. It will take the train 16 days to complete the journey, and it will bring 34 carriage loaded with goods made in Yiwu.  

The new train route is expected to herald in a new era in trade relations between the UK and China. Goods sent via the train route will travel faster than if they traveled via a container ship. Train shipping is also less expensive than shipping by air. 

The East Wind from Yiwu to London will start out running once a week on a trial basis. East Wind, owned by China’s Yiwu Timex Industrial Investment, also features a route from Madrid to Spain that runs twice a week.

The Silk Road journey has always been a difficult one. It features a route that winds through treacherous mountains, around blazing deserts, and across endless miles of the Russian steppe. Before the advent of wheeled travel, merchants who ventured on the Silk Road had to have a constant supply of fresh horses to complete their journey.

Today’s Silk Road may not require fresh horses, but it does require different trains. The route pushes through Russia, Kazakstan, Belarus, Poland, Belgium, and finally France, all before it arrives in London. Because each country has different rail gauges on its train lines, the same train can’t complete the entire journey.

NuScale Power wants small-scale nuclear reactors to be part of the planet’s future energy portfolio. To that end, they’ve submitted designs for a small modular reactor to the <a href="https://www.nrc.gov/reactors/advanced/nuscale.html">U.S. Nuclear Regulatory Commission</a>.

Bonus: No meltdowns. At least, that’s what the small size is supposed to ensure.

The design <a href="http://www.nuscalepower.com/">NuScale Power</a> submitted is for a small modular reactor, or SMR, that can be factory-built and shipped to a destination for assembly.

On top of providing nuclear power, it can refine oil, desalinate saltwater, produce hydrogen, and more. The modular design means it can be built in a number of sizes and fit into existing power plant designs.

Each module is so small that the surface area is much larger compared to the volume than that ratio is in a traditional nuclear reactor. That design ensures heat can be siphoned off easily, and a meltdown is next to impossible.

Each of the SMRs produces about 50 megawatts of power, and they can be paired with other energy sources or put together in a “12-pack” to produce 600 mW, the company said.

The firm is the first to submit an SMR design to federal regulators. Because their design is the first, it may take some time – as long as 40 months – for it to wind its way through the approval process, if it’s approved at all.

NuScale Power has taken steps to make approval a slam-dunk, though.

The company invested more than $30 million in testing the SMR design, including building large-scale test facilities and a control room simulator so they could run through every scenario imaginable.

NuScale Power submitted more than 12,000 pages of technical and design information to the NRC to ensure regulators have everything they need to begin their review.

The SMR design has been in the works for nearly 20 years. The early research began at <a href="http://oregonstate.edu/">Oregon State University</a>, led by Dr. Jose Reyes, a physicist who co-founded the company and now serves as its chief technical officer.

If the NRC approves the design, NuScale has developed a teaming arrangement with the <a href="https://energy.gov/">U.S. Department of Energy</a>, the state of Utah, and <a href="https://www.energy-northwest.com/">Energy Northwest</a> to build the first <a href="http://www.earth.com/news/indian-point-3-nuclear-power-plant-shuts-down/">reactor</a> in Idaho.

The multimillion-dollar sushi market in places like the UK and Southern California may be damaging our oceans as well as our bodies, according to leading marine biologists. Not only has the trendiness of the fish dish led to a sharp decline in the tuna population, but it’s also responsible for filling our bodies with harmful microbeads.

Sushi’s reputation as an exotic, low-calorie, vitamin rich food has won it the endorsement of Hollywood celebrities and health food aficionados alike. But according to Dr. Daniel Pauly and Dr. Kirk Zeller from the <a href="https://www.ubc.ca">University of British Columbia</a> in Canada, sushi’s popularity as a source of heart-healthy omega-3 fatty acids has placed bluefin and yellowfin tuna populations at "crisis" levels.

“Historically we have had the ‘Popeye effect’ where everyone ate spinach; then vitamin D was good and vitamin C would save us from having cancer,” Pauly said. “Now it is omega-3 – all these things are going to save us, make us healthy and we are going to live forever. None of this is true – what we  need is a balanced diet.”

Pauly is also convinced that plastic microbeads – used in personal care products and makeup – can be found in the sushi served in sushi bars. The microscopic plastic fragments, recently banned in the U.S. and the UK, attract and carry pesticides and industrial chemicals.  

“Microbeads are poison pills which soak up all the pollutants and they are consumed by little fish which are then eaten by tuna,” Pauly said.

Bluefin tuna, often served in high-end Japanese restaurants, and yellowfin tuna, usually used in supermarket sushi rolls, are in high global demand, and the global tuna population is falling. 

“We are in permanent crisis if you look at it in historic terms. Bluefin tuna was extremely abundant, especially in the Mediterranean. What has become of that? We have 2 to 3 percent of what we had 200 years ago,” added Pauly.

Zeller also warns that sushi is not as healthy as it was once purported to be. High levels of mercury and polychlorinated biphenyls (PCBs) found in waterways are suspected to cause cancer in people.

The post-apocalyptic world of endless desert and dust bowls in Mad Max: Fury Road featured a tyrant who lorded over the starving and dehydrated masses by controlling a huge tank of drinkable water. The sci-fi film may have been more realistic than we knew, as a new affordable water crisis may be developing in the U.S.. 

A new study by <a href="https://msu.edu">Michigan State University</a> scholar and assistant geography professor Elizabeth Mack asserts that if water rates continue to rise as projected, the number of U.S. households unable to afford water could triple by nearly 36% in as few as five years. 

In her study, one of the first nationwide investigations of water affordability, Mack attributes the developing water crisis to a number of factors, including aging infrastructure, climate change, and declining populations in urban areas. 

“In cities across the United States, water affordability is becoming an increasingly critical issue,” Mack states. Her study, published online in the journal <a href="http://journals.plos.org/plosone/">PLOS ONE</a>, analyzes water pricing, consumption, socioeconomic and demographic data. 

The <a href="https://www.epa.gov">Environmental Protection Agency</a> recommends that spending on water and wastewater services combined should amount to no more than 4.5% of household income. If true, some 13.8 million U.S. households (nearly 12% of all households) may be unable to pay their water bills. She says that poor families are being hit especially hard by these statistics. 

Since 2010, water rates have gone up 41%. If that trend continues, an estimated 40.9 million households (35.6% of all households) will be unable to afford water and wastewater services in five years.

Regarding aging infrastructure, experts predict it will cost more than $1 trillion over the next 25 years to replace World War II-era water systems. Climate change is expected to introduce more severe weather events and require improvements to wastewater facilities. These fixes are estimated to cost the U.S. more than $36 billion by 2050.

In addition to that, shrinking populations in major cities results in fewer households paying for the large fixed cost of water service.  In Philadelphia, 40% of water accounts are past due. In Detroit, 50,000 households have been unable to pay their bills and had their water service terminated since the beginning of 2014.

The study says that governments, utilities and consumers will have to work together to fix the issue.

“Water is a fundamental right for all humans. However, a growing number of people in the United States and globally face daily barriers to accessing clean, affordable water,” says Mack. “The hope that is enhanced awareness of this issue in the developed world will highlight the severity of the issue, which is not isolated to people in the Developing world.”

Garbage food

Edible foods trashed by UK families total billions. New figures released today by the waste and recycling advisory body<a href="http://www.wrap.org.uk/category/materials-and-products/food"> Wrap</a> claim UK households threw away £13 billion worth of edible food in 2015. This staggering figure amounts to around £470 per household, equating to nearly $13.7 billion in U.S. currency, or around $500 per household.

The data report revealed that an estimated 8 million metric tons of household food waste was thrown away in 2015, up from 7.7 million metric tons in 2012.

Of the food thrown away by UK households, over half was recorded as “avoidable” waste, which means it was edible before being thrown in the trash.

The report also added that these avoidable waste products generated over 20 million metric tons of greenhouse gas production over their lifetime. To prevent that pollution you would need to take 25% of cars off UK roads.

Wrap cites the root cause of this food waste increase as the perfect storm of falling UK food prices coupled with rising household incomes since 2014. The report indicates these factors may have increased the notoriously thrifty UK population to be less frugal during regular shopping.

This data shows an abrupt stop in what had previously been a downward trend in UK household food waste. Between 2007 and 2012, the total amount of household food waste dropped by 15 percent and avoidable waste dropped by 21 percent. Wrap credits this to the rising food prices at the time, along with changes to labeling that simplified “use by” date advice, as well as active campaigning that raised awareness of food waste.

Regionally, Wales actually showed significant progress in cutting food waste in the UK with a 12% percent food waste reduction since 2009. This may be due to a devolved administration and a greater availability of civic-run food waste collections.

Trewin Restorick, the founder and chief executive of environmental charity<a href="https://www.hubbub.org.uk/"> Hubbub</a> – a major food waste project for<a href="https://www.theguardian.com/business/j-sainsbury"> Sainsbury’s</a> in Derbyshire – said, “Seeing food waste grow again is massively disappointing and should be a wake-up call for efforts to be redoubled. [The Department for Environment, Food, and Rural Affairs] needs to copy the leadership being shown in Wales and Scotland.”

Imagine buzzing across the Hudson River or around the San Francisco Bay on a boat that actually floats above the water. It could happen sooner than you might think. Flying water taxis are now one step closer to becoming a reality now that its investors have received a new round of funding. 

Yachtsman Alain Thébault and Swedish windsurfer Anders Bringdal have teamed up to design these “flying water taxis” otherwise known as the Sea Bubble. The unique vehicles will float 2 feet above the water, capable of reaching speeds up to 18 miles per hour. 

The team raised $3.6 million for the project last month, and have just announced they are expecting an additional third round of funding. Thébault told <a href="https://www.bloomberg.com/news/articles/2017-01-11/flying-river-taxis-eye-customers-from-the-seine-to-san-francisco">Bloomberg</a> that the next installment could be up to 10 times that amount.

Production of the flying water taxis will begin next month, and testing will occur in Paris in the spring. Test vehicles will be able to carry up to 6 passengers at a time.

Thébault told <a href="http://www.telegraph.co.uk/news/2016/10/27/paris-to-trial-flying-river-taxis-in-the-seine-next-year/">The Telegraph</a> that he envisions SeaBubbles will ultimately be available to order on an app like Uber. 

The technology powering SeaBubbles was originally invented by Thébault in 1994 for a sail-powered vessel he called Hydroptere. Instead of floating along the the water like a typical boat, the Hydroptere channels a similar model that planes use to fly, where air passes over the wings and generates lift.

By floating above the water, the Sea Bubble avoids up to 40% of the drag imposed by water flow. Because the boat is electrically powered, it remains very quiet and produces zero emissions. 

Trips on the Sea Bubble will cost roughly $12. 

“The idea actually came from my daughters after I sailed from LA to Hawaii recently,” Thébault told <a href="http://www.thelocal.fr/20161027/paris-flying-river-taxis-to-be-tested-on-seine-sea-bubbles">The Local</a>. “They told me to invent a zero-emission cab because they were sick of seeing the pollution in Paris, London, and the US." 

“Next spring we will hold a public demonstration on the Seine in front of the National Assembly in Paris with five Sea Bubbles”

The Center of Science and Industry in Columbus, Ohio, is the place to be if you want to learn more about the world.

At least, some of the brightest minds in the United States think so. MENSA has listed the museum in its <a href="https://www.us.mensa.org/welcome-to-our-site/the-mensa-top-ten-survey/mensa-top-ten-science-museums/">top 10 American science museums</a>, and it won a coveted nod as the top family-friendly science center in America from <a href="http://www.parents.com/fun/vacation/us-destinations/best-science-centers/">Parents Magazine</a>.

<a href="http://cosi.org/">COSI</a> has earned that praise.

“COSI ... inspires the scientists, dreamers, and innovators of tomorrow,” the museum declares on its website.

The science center, which first opened in 1964, offers more than 300 hands-on activities. It has partnered with the Columbus community to offer unique attractions like the WOSU@COSI television station; Labs in Life, working research labs created in partnership with <a href="https://www.osu.edu/">Ohio State University</a> and staffed by working scientists and students; and a gallery of Columbus, Ohio’s history sponsored by the <a href="http://www.columbushistory.org/">Columbus Historical Society</a>.

Full of brightly colored, kid-friendly exhibits, the Center of Science and Industry is located near Genoa Park. That makes it a great option, whether you want to spend the day getting as much use as possible out of a Do-It-All pass, or just spend a few hours with some hands-on fun before or after a picnic lunch.

The Do-It-All ticket is more winter-friendly, of course! It includes all of COSI’s classic exhibits, along with the Planetarium and Motion Simulator. Do-It-All also includes a 3-D movie at the National Geographic Giant Screen Theater.

The Motion Simulator and the Giant Screen Theater both use modern tech to make it feel like you’re in space, under the ocean, or beyond.

Recent showings at the National Geographic theater have included “Journey to the South Pacific” and “Secret Ocean.”

Of course, those are just the extras. It’s COSI’s classic exhibits that have been the heart of the museum for decades.

They’re divided up into areas like Big Science Park, an outdoor lab where visitors learn about basic physics and green engineering; Ocean, where kids can learn about how water works and pilot an underwater ROV; and Space, which has interactive simulator stations where guests can try landing the Space Shuttle.

There’s also the ever-changing line-up of speakers and live shows, as well as special events geared toward certain age groups. Camp COSI is for kids in kindergarten through fifth grade, while COSI After Dark lets legal drinkers explore the museum while enjoying the no-host bar and small plates.

The Center of Science and Industry also offers special programs for educators.

If you’re in the Columbus area, stop by and spend a day with COSI. You’ll have so much fun, you won’t even notice you’re learning.

To purchase tickets and plan your visit, go to the <a href="https://reservations.cosi.org/Info.aspx?EventID=19">COSI tickets website</a> or call (614) 228-2674.

What’s going on in the world today? Plenty. In your daily dose of Earth news for January 9, 2017, you'll find a new nature miniseries, tips on algae growth, potential uses for earwax, and more.
<h2>Earth news for January 9, 2017:</h2>
<h4>BBC launches ‘Spy in the Wild’</h4>
With “Planet Earth II” over, nature fans are looking for their next fix. “<a href="https://www.youtube.com/watch?v=lfdrQL5Ff-A">Spy in the Wild</a>” aims to provide it. The new <a href="http://bbc.co.uk/">BBC</a> documentary conceals cameras in lifelike robots, and sends them to watch animals in their natural habitats.

Maybe they're a little too lifelike. In the first episode, a robot disguised as a langur monkey successfully infiltrates a group in India. When the robot was dropped from a height, the monkeys began mourning, producers said.

The miniseries airs in the UK beginning Thursday. In the U.S., the first episode will run February 1 on <a href="http://www.pbs.org/wnet/nature/">PBS Nature</a>.
<h4>Could earwax be the next big tech innovation?</h4>
Scientists at the <a href="http://www.gatech.edu/">Georgia Institute of Technology</a> have taken on a new – and sort of disgusting – project: figuring out a technological use for earwax.

The project was inspired after her boyfriend had water trapped in his ear by an earwax plug, doctoral student Alexis Noel said. She wondered how the earwax was able to allow the water in, then trap it so effectively, and mentioned it to Dr. David Hu. They decided to take on the problem.

Using earwax from pigs, sheep, rabbits, and dogs, they began testing its properties and trying out different uses. They’ve found that earwax is made up pretty consistently across species.

They also found that it has excellent filtering properties. As earwax collects dust, it traps it. When too much dust is trapped, the earwax crumbles and falls away, and new wax is formed.

While they’re still studying exactly how earwax is formed, the researchers already see potential uses in tech. One idea would be to create a biomimetic adhesive surface for ventilation systems in robotics and other machinery.
<h4>Colorful new flatworm species discovered in Brazil</h4>
Scientists have found three new land-based species of flatworm in the Araucaria forest of Brazil. Flatworms are invertebrates, and also predators that hunt other invertebrate species.

The Araucaria is part of Brazil’s Atlantic Rainforest and is considered to be a hotspot of flatworm diversity, the scientists wrote in their article in <a href="http://zookeys.pensoft.net/articles.php?id=11093">ZooKeys</a>, an open access journal. The three new species belong to the genus Cratera.
<h4>In forests, Missouri bees prefer darker flowers</h4>
Bees prefer darker colors in cool climates, at least when it comes to flowers. That’s what scientists at <a href="https://www.slu.edu/">St. Louis University</a> discovered while observing how native bee species interact with birds foot violets.

In most cases, the bees prefered the concolor morph, in which all five petals of the flower are light in color. In sunny locations, the concolor morph far outnumbers the bicolor morph, which has two dark purple petals and three light ones.

But in shady, wooded areas, the bicolor morph makes up about half of the flower population. Bees in these areas always land on the darker petals to feed, the researchers found. Testing revealed darker petals were warmer.
<h4>Scientists at UC Irvine find a new method for recycling greenhouse gases</h4>
A team of researchers from <a href="https://uci.edu/">University of California, Irvine</a> has discovered a new method for dealing with carbon dioxide: using it to help produce biofuel.

The bacterium Azotobacter vinelandii can be used to convert carbon dioxide into carbon monoxide. Though toxic in enclosed spaces, carbon monoxide can be used to produce biofuels and chemical products. Their findings were published in the journal <a href="http://www.nature.com/nchembio/journal/vaop/ncurrent/full/nchembio.2245.html">Nature Chemical Biology</a>.
<h4>Biodiversity of algae is important in biofuel production</h4>
<a href="https://www.umich.edu/">University of Michigan</a> researchers studying algae-derived biocrude have found that when raising algae, biodiversity is important. They found that growing a wide variety of algae reduced crop failure and gave a better return on investment. While their research was conducted indoors in tanks, that will be true in outdoor tanks or ponds, too, the researchers said.

The research is being funded by a $2 million, four-year grant from the <a href="http://www.nsf.gov/">National Science Foundation</a>.
<h4>Scientists explore link between rainfall in West, Rocky Mountain air quality</h4>
When the western U.S. suffers from a drought, Rocky Mountain air quality suffers, too, scientists at the <a href="http://www.utah.edu/">University of Utah</a> found.

That’s because drought sparks more wildfires, which creates haze in the Rockies, the scientists said. Haze can be evaluated with instruments that measure aerosol optical depth – the amount of aerosols between the sensor and the sun.

Aerosols in the Rockies went up when the west was in a drought, according to the study published in the journal <a href="http://iopscience.iop.org/article/10.1088/1748-9326/aa510a/meta;jsessionid=5E21027595D39B0B34BD2C5716CCDC9D.c4.iopscience.cld.iop.org">Environmental Research Letters</a>.

Earth news daily: January 9, 2017

What’s going on in the world today? Plenty. In your daily...

Cities in northern England have a new and growing segment of the population: urban foxes. And they're not the only places with an influx of non-human newcomers.

Researchers are taking note of a growing trend among wildlife. Feral cats, mice, raccoons, and starlings are being joined by more exotic urbanites such as foxes and coyotes.

A team led by Dr. Dawn Scott of <a href="https://www.brighton.ac.uk/">University of Brighton</a> has discovered that urban fox populations in England have exploded in recent years. Numbers clocked in at 33,000 then, and they've risen to 150,000 today, they told <a href="http://www.dailymail.co.uk/sciencetech/article-4087010/A-country-overrun-foxes-Numbers-creature-FIVE-TIMES-higher-England-s-cities-thought.html">The Daily Mail</a>. Particularly in the northern towns of England, fox numbers have multiplied rapidly in the past two decades.

Protection from hunters and plentiful food have led many animals to begin calling cities home. And they're adapting and learning how to change their lifestyles around human activity to better fit in.

“We are the biggest cause of evolution on the planet right now,” Dr. Suzanne MacDonald, a psychologist and biologist at York University in Canada, told <a href="http://news.nationalgeographic.com/2016/04/160418-animals-urban-cities-wildlife-science-coyotes/">National Geographic</a> in April 2016.

England's urban foxes demonstrate this well. Even though fox communities have grown in urban areas, human residents of cities report seeing the furry creatures much less. Foxes are either becoming part of the city scenery, or getting a lot better at avoiding attention.

Urban foxes aren't the only ones moving into cities. Coyotes, hedgehogs, and other wild creatures have joined metropolitan standards like squirrels, raccoons, and feral pigeons. Some come for the safety and better meals. Others have nowhere else to go.

“To live in harmony with animals whose habitat we’re destroying, we’re going to have to do a lot more work in what we’re doing to them,” MacDonald said.

Several major cities put a lot of effort into protecting their wild animal populations.

<a href="http://www.architecture.org/architecture-chicago/buildings-of-chicago/building/aqua/">Aqua Tower</a> in Chicago is designed with exterior terraces to look more like a cliff, which prevents birds from crashing into it as frequently. In Germany, Berlin plans to adopt “coherent greenery,” where they will connect the green spaces within the city so that wildlife can move around more easily.

Efforts are even being made in Los Angeles to build a land bridge over the 101 Freeway, which would allow mountain lions to mingle rather than live in isolation.

Some of the newly urban animals, such as red foxes and coyotes, have traits that let them successfully exist in cities without much human help.

Animals that survive and thrive in the wild by being sneaky, adaptable, and fast breeders – and those that aren’t fussy about what they eat – tend to do very well in cities, said Tristan Donovan, author of <a href="https://www.amazon.com/Feral-Cities-Adventures-Animals-Jungle/dp/1569760675">Feral Cities: Adventures with Animals in the Urban Jungle</a>.

Red foxes actually live in greater densities in cities than in the country now, and city-dwelling coyotes tend to live longer than their rural counterparts, scientists said.

“It’s a pattern we’ve seen across the whole continent – they’re figuring out a way to deal with whatever we’ve done to the landscape,” Dr. Chris Nagy, a wildlife biologist, told National Geographic. Nagy has studied coyote populations in New York City for years.

<a href="https://www.srs.fs.usda.gov/sustain/report/terra3/terra3-13.htm">Studies</a> have shown that human development almost always leads to decreased biodiversity. But urban foxes and other city-dwelling wildlife show that many species can adapt and thrive in human cities.

Their presence can sometimes be dangerous. Animals such as mountain lions and coyotes can become bolder as they grow more accustomed to human contact.

However, many cities are finding solutions to help animals coexist with humans. Human development of their native environments leaves few alternatives.

Urban foxes and other animals settle into cities, raise families

On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.



This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.



Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.



The find upsets the traditional timeline of sea predators. Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas. These worms were building sophisticated food webs several million years before other predator groups arose.



Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.



Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.



<h2 class="wp-block-heading" id="h-the-cairo-forest-discovery">The Cairo forest discovery</h2>



385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.



The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.



Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."



This discovery pushes back advanced tree evolution by millions of years. The research, published in <a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a> in December 2019, fundamentally changes our understanding of when complex forests first emerged.



Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet Archaeopteris: the first modern tree</h2>



The star of this ancient forest is Archaeopteris – not to be confused with the feathered dinosaur Archaeopteryx. This tree was far older and more revolutionary.



William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.



Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.



This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



The forest was remarkably diverse. Scientists identified Eospermatopteris, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.



All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.



<h2 class="wp-block-heading" id="h-scientific-significance">Scientific significance</h2>



Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.



Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."



The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.



Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.



Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.



These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.



The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.



The full study was published in the journal Current Biology.

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

Mid-July is an opportune time to kick-start a thriving fall garden, and this guide lays out the best vegetables and herbs to plant now for a fruitful autumn harvest. 



Fast-growing leafy greens such as spinach, lettuce, kale, and arugula perform especially well in the waning summer heat, with harvests beginning as soon as 30 days. 



These cool-season crops relish the transition into fall, offering repeated yields with cut-and-come-again methods.



Root vegetables like radishes, carrots, and beets also excel during this period. Radishes deliver satisfaction in under a month, while carrots and beets mature in about two months. Employing succession planting ensures a continuous stream of produce deep into the cooler months. 



For a boost of fresh flavor, herbs like cilantro, basil, dill, and chervil are excellent picks. These heat-loving varieties flourish in July’s warmth and are harvest-ready in about 30 days, especially when sown continuously.



Gardeners in zones 6 through 9 can benefit from planting bush beans and snap peas, which don’t require trellising and are ideal for compact plots. 



Maturing in 50–60 days, they’re a smart choice for quick, protein-rich harvests. For those in hotter regions, heat-tolerant crops such as okra and southern peas provide reliable yields and thrive in scorching conditions.



This guide emphasizes more than crop selection—it highlights the importance of timing, soil preparation, and ongoing sowing techniques. 



With thoughtful planning and attention to regional climate needs, even late-summer gardeners can enjoy fresh salads, hearty stews, and the satisfaction of a robust, homegrown harvest well into fall.

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

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."
