1 . In the hands of a skilled stylist, your hair can help you boost your self-confidence, express your unique personality, and maybe even attract a romantic partner. In the hands of Matter of Trust, however, your hair might be able to do something even more meaningful: help save the environment.
For more than 20 years, Matter of Trust has been collecting hair and fur from hair salons, and farmers around the world for the purpose of making “hair mats” that can assist with oil spill cleanups.
Typically, oil spills on land are cleaned up using polypropylene (聚丙烯) mats that are effective but might cause environmental problems. After all, polypropylene is a non-biodegradable (不可生物降解的) plastic that’s made from fossil fuels; using it to clean up oil therefore requires drilling for even more oil. Hair and fur, on the other hand, are of no poison, biodegradable, sustainable, and can absorb more oil.
To date, Matter of Trust has produced more than 40,000 hair mats and more than 300,000 booms, reports CNN. Matter of Trust’s products have been used to clean up not only oil spills, but also non-emergencies like oil leaks from vehicles and machines. In both cases, oil can flow into soil and water, which can harm people, plants, and wildlife, according to Matter of Trust.
Although it’s an elegant solution, it isn’t perfect. Hair mats can only be used once, for instance, and can only be dealt with through incineration (焚化) or composting (堆肥). And in the case of composting, the resulting compost isn’t suitable for growing food.
Still, hair mats are a surprisingly effective tool in the fight for a cleaner planet. And because Matter of Trust hasn’t patented its designs, all that’s needed to produce them are hair cuttings—of which there are plenty, according to Gautier, who says there are about 900,000 qualified hair salons in the U.S. alone, each of which can easily cut at least a pound of hair per week.
“Anyone can make a hair mat,” she told CNN. “It creates green jobs, it cleans water, it reduces waste, and it’s promoting sustainable resources.”

2 . People have long watched moths (飞蛾) and other flying insects flock to streetlamps, lights and flames. These insects appear attracted by the light. But a new study suggests they may just lose track of which way is up.
Previous theories say light probably blinds flying insects so that they get trapped by the light, or maybe they interpret light at night as a place to fly for a quick escape. Now the new study suggests flying insects instead turn their backs to the sky’s light to keep their feet pointing toward the ground. Insects naturally turn their backs toward light. But when that light is from an artificial source, it may affect their sense of direction, leading to them flying in circles or diving toward the ground.
At a field station in Costa Rica, Samuel Fabian, an entomologist from Imperial College London in England and his teammates set up hanging and standing lights, and then used high-speed cameras to track wild, flying insects including moths and flies. Some circled the lights endlessly, and others flew sharply upward, losing speed until they couldn’t fly any higher. When the light source pointed up, some insects turned around and headed for the ground. During the flight, the insects always kept the lights at their back even if they’d end up crashing. Crash landings were common when the team lit up a white sheet on the floor. But not when a white sheet — stretched into a height above the floor—was bathed in diffuse (漫射) light, much as the sky would be, insects flew through the area without getting trapped by the light.
The team also observed some species in a lab. Moths and dragonflies generally behaved like the wild insects, and they kept the light at their backs. However, in the lab, fruit flies, like oleander hawk moths — which can fly in the dark — could fly over LED lights without being thrown off course. In the wild, though, the moths still crashed. Maybe this is because, Fabian says, the insects can sometimes control their response to light, or over time, they might learn to avoid artificial light.

4 . Asian short-clawed otters (水獭) can teach each other how to solve puzzles to get food, according to a new study that took place in England. The research also showed that these cute animals have a good long-term memory —they could remember how to solve the puzzles even after several months.
Scientists from University of Exeter observed groups of Asian short-clawed otters in different places. They gave each group a selection of transparent (透明的) containers with meatball treats inside. Each box could be opened by twisting or pulling a particular lid or handle.
To get the food, the otters had to solve the puzzle of how to open the containers. The otters had two attempts at the puzzle several months apart. The researchers found that if one otter cracked the puzzle, its closest friends quickly solved it, too. The findings provide evidence of “social learning”—animals can learn from each other.
The scientists also found that on average the otters solved puzzles 69% faster the second time. It means that they can remember the details of how each puzzle works. “Our study is the first to show evidence of social learning and long-term memory in Asian short-clawed otters, which may be good news in terms of their adaptability and future survival,” said Alex Saliveros, lead author of the Centre for Ecology and Conservation on Penryn Campus in Cornwall.
Saliveros says the findings are important, because Asian short-clawed otters are declining in the wild, partly due to overfishing and pollution affecting the crustaceans and small fish they feed on. The discovery that the otters are able to find food in new ways and to pass on that knowledge toothers could be significant to their long-term survival.

6 . Unless you’ve been faithfully bringing reusable shopping bags to the store, you probably grab the plastic bags waiting for customers at the checkout. You’re not alone.
About 100 billion plastic bags are used in the U. S. each year. Unfortunately, single-use plastic bags have serious consequences once our trip to the store is over. Less than 10% of plastic bags used in the U. S. are recycled, leaving the rest to end up in landfills (垃圾填埋场), and polluting soil, oceans and other natural habitats.
To fight pollution and other environmental problems, major companies are taking steps to get rid of the use of plastic shopping bags. If you’re a frequent customer at Walmart, don’t be surprised if you notice the plastic bags disappearing over the next few months. Last summer, Walmart announced its goal to be a zero-waste company — meaning no more plastic bags.
But Walmart has announced its Beyond the Bag, an initiative (倡议) working to explore reusable options and “reimagine” the plastic bag. Target and CVS are also on board as founding partners of Beyond the Bag, and so far, the three brands have invested $15 million to come up with a brand-new bag design.
The initiative also started the Beyond the Bag challenge, giving innovators (创新者) a chance to share their ideas. The challenge ran throughout the summer of 2020, and nine winners from over 450 submissions were selected. From a station supplying reusable bag in-store to a new and improved paper bag, the winning designs cover a lot of bases. Each product now has the chance to be tested with funding from the initiative.
While a final replacement for plastic bags at Walmart has yet to be decided, there’s a more sustainable future on the horizon. And if you want to start reducing your use of plastic bags right now, check out our list of reusable bags to bring on your next shopping trip.

7 . Great whites, the largest predatory(捕食性的)sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Wildlife filmmaker Carlos Gauna and UC Riverside biology doctoral student Phillip Sternes were scanning the waters for sharks on July 9, 2023, near Santa Barbara on California’s central coast. That day, something exciting appeared on the viewfinder of Gauna’s drone camera. It was a shark pup(幼崽)unlike any they’d ever seen.
“We enlarged the images, put them in slow motion, and realized the white layer was being shed(脱落)from the body as it was swimming,” Sternes said. “I believe it was a newborn white shark shedding its embryonic layer.”
These observations are documented in a new paper in the Environmental Biology of Fishes journal. What Gauna and Sternes observed could help solve the longstanding mystery of great white birthing habits. This may well be the first evidence we have of a pup in the wild. Great whites, referred to only as white sharks by scientists, are gray on the top and white on the bottom. But this roughly 5-foot-long shark was pure white.
Though the paper authors acknowledge it is possible that the white layer the shark shed could have been a skin condition, the two believe what they saw was in fact a newborn great white. First, great white females give birth to live pups. A second reason is the presence of large, likely pregnant great whites in this location. Finally, this location off the coast of central California has long been proposed as a birthing location for great whites. Many scholars believe great whites are born farther out at sea.
Great whites are listed as an international endangered species. “Further research is needed to confirm these waters are indeed a great white breeding ground. But if it does, we would want lawmakers to step in and protect these waters to help white sharks keep thriving,” Sternes said.

8 . The morning commute(通勤)is never fun, but if you pass through Stevenage on your way to work, your morning might be a little brighter thanks to Nala the cat.
Dragging yourself out of bed in the morning and off to work is hard, especially on dark winter mornings. You might be a little more inclined to head out of the house with a spring in your step if your commute started at Stevenage Station, where you’d be greeted by a ginger cat called Nala.
Usually found sitting on a ticket gate, four-year-old Nala lives close to the station with her owner Natasha Ambler, and often heads to station at rush hour to enjoy attention from commuters. Ambler created a social media page called The Adventures of Nala where hundreds of people have shared photos of the adventurous cat.
Recent photos include Nala waiting in line for her “cat-purr-ccino” at Costa, snoozing(打盹)on newspaper stands and posing with commuters at the station barriers.
Nala wears a GPS tracking device so that her travels can be traced, and is usually found at the railway station or the next door leisure park. As well as the usual collar with her name and owner’s contact information, Nala wears a tag to let people know that she’s not lost.
Ambler reported that she’s not worried about Nala in the slightest: She’s obviously well-loved and she’s very happy doing what she does—I just hope one day she doesn’t actually try to get on a train.
Nala brings a ray of joy to Stevenage commuters with her playful antics. Her presence not only brightens mornings but also fosters a sense of community, as evidenced by the shared photos and interactions on social media. Her owner’s care and Nala’s adventurous spirit ensure that she’s a beloved and safe addition to the station environment.

10 . The climate crisis may lead the human race to decrease in size, as mammals (哺乳动物) with smaller bodies appear better able to deal with rising global temperatures, a leading fossil expert said.
Prof Steve Brusatte, a palaeontologist (古生物学家) at the University of Edinburgh, suggested that the way in which other mammals have previously responded to periods of climate change could offer an insight into humans’ future.
He compared the potential situation of people as similar to that of early horses, which became smaller in body size as temperatures rose around 55m years ago, a period called the Paleocene Eocene Thermal Maximum.
Writing in The Rise and Reign of the Mammals, Brusatte notes that animals in warmer parts of the world today are often smaller than those in colder areas, an ecological principle known as Bergmann’s rule. “The reasons are not entirely understood, but it is probably, in part, because smaller animals have a higher surface area compared to their size than bigger animals and can thus better get rid of extra heat” he writes.
Brusatte said that becoming smaller was “a common way that mammals deal with climate change”. He added, “That’s not to say every species of mammal would get smaller, but it seems to be a common survival trick of mammals when temperatures spike pretty quickly, which does raise the question: if temperatures do spike really quickly, might humans dwarf, might humans get smaller? And I think that’s certainly convincing.”
In a recent study, researchers studying human remains over the past million years have also suggested that temperature is a major predictor of body size variation, while scientists studying red deer have said that warmer winters in northern Europe and Scandinavia may lead to the body size of these animals becoming smaller.
However, not all experts agree that rising temperature causes mammals to decease. Prof Adrian Lister, of the Natural History Museum in London, said the relationship shown by the recent human remains study is weak, while the strong relationship between temperature and mammal body size may often result from the availability of food and resources.
Lister doubts whether humans will shrink as the climate heats. “We are not really controlled by natural selection,” he said. “If that was going to happen, you’d need to find large people dying before they could reproduce because of climate warming. That is not happening in today’s world. We wear clothes, we have got heating, we have got air conditioning if it is too hot.”
