1 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.
In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.
Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.
Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

2 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.
But hair possesses useful qualities and it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks,
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.
“Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier, “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.
Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氪), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes-for oil and soil, ” Hama says.

3 . Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world’s ocean’s food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!
Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. They adapt well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one third of the 400 shark species are in danger of extinction, largely due to over-fishing. Each year, tens of millions of sharks are caught and killed just for their fins. The fins are used to make shark fin soup.
Humane Society International(HSI) joined with the Jane Goodall Institute’s Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, “The Price Behind the Taste — Protect Sharks. Don’t Eat Shark Fins”, was designed to tell people that shark finning is cruel and unnecessary. It’s hoped that the activity will help put an end to the practice.
Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.

For the most part, Hank, a two-year-old cat, is a homebody — and for good reason. But on November 6th, Bushong, his owner, spotted Hank resting on a branch near the top of a neighbor’s tree. Bushong believed Hank got frightened by some dogs. The more scared he got, the higher he climbed. “Cats have an amazing ability to climb up trees, but they aren’t that good at climbing down,” said Dan D’Eramo, director of field services for the Humane Rescue Alliance (HRA). Bushong then asked the HRA to help, but it was no easy task. HRA called the fire department, but it refused to help because of safety concerns. Then Bushong called a construction company to ask about renting scaffolding (脚手架) , but was told she would have to book the equipment 48 days in advance. Next she reached out to a local tree company, Casey Trees. But the crew said it wasn’t safe for a person to go up into the tree.
Bushong became very sad. Then neighbors came to help. Ed Baptiste, whose tree Hank had climbed, let Bushong sit in his backyard and called to Hank. Another neighbor donated a can of fish, hoping it might attract the cat to come down. Nearby dog owners took their pets on walks instead of letting them out in their yards to avoid further frightening Hank. Another neighbor suggested Bushong call a local business, which had a tall ladder. Unfortunately, their 42-foot ladder proved too short. By day five, nothing had worked. That’s when another neighbor suggested creating a pulley(滑轮)system by throwing a sandbag attached to the rope to a branch higher than Hank. It will form a pulley system as the sandbag hangs down by gravity. Then raise a basket with some of the owners’ personal items. The cat may be attracted by the familiar scents and climb into the basket.注意：

6 . Artificial intelligence (AI) is showing promise in earthquake prediction, challenging the long-held belief that it is impossible. Researchers at the University of Texas, Austin, have developed an AI algorithm(算法) that correctly predicted 70% of earthquakes a week in advance during a trial in China and provided accurate strength calculations for the predicted earthquakes.
The research team believes their method succeeded because they stuck with a relatively simple machine learning approach. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI provided its prediction by listening for signs of incoming earthquakes within the background rumblings(隆隆声) in the Earth.
This work is clearly a milestone in research for AI-driven earthquake prediction. “You don’t see earthquakes coming,” explains Alexandros Savvaidis, a senior research scientist who leads the Texas Seismological Network Program (TexNet). “It’s a matter of milliseconds, and the only thing you can control is how prepared you are. Even with the 70% accuracy, that’s a huge result and could help minimize economic and human losses and has the potential to remarkably improve earthquake preparation worldwide.”
While it is unknown whether the same approach will work at other locations, the researchers are confident that their AI algorithm could produce more accurate predictions if used in areas with reliable earthquake tracking networks. The next step is to test artificial intelligence in Texas, since UT’s Bureau TexNet hastions and over six years worth of continuous records, making it an ideal location 300 earthquake sta for these purposes.
Eventually, the authors hope to combine the system with physics-based models. This strategy could prove especially important where data is poor or lacking. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.
