4 . The moment the ground stops shaking after an earthquake, some people may wonder whether their pets — or wild animals for that matter — knew the disaster was coming.
To get to the bottom of this question, Heiko Woith, a scientist at the German Research Centre for Geosciences, and his colleagues evaluated more than 700 published reports of unusual behavior among 130 species, including insects, birds, fish, cats, dogs and cattle from 160 earthquakes. The records included all kinds of behaviors, including a tiger that reportedly got depressed before an earthquake.
The researchers found that 90 percent of all reported cases happened within 62 miles of the epicenter (震中) and within 60 days of an earthquake. Then, they examined when and where foreshocks had happened in the region and concluded that it was hard to say these animals could predict the earthquake itself. They were just responding to foreshocks.
“The space-time pattern of animal precursors (预兆) and foreshocks is strikingly similar,” Woith said. “From this, we concluded that the abnormal animal behavior might simply be related to foreshocks. These animals are just responding to foreshocks rather than predicting the earthquake. They don’t have super power.”
Despite the vast number of incidences, good information was little and scientific evidence is lacking. “A major surprise for us was that the large majority of the published claims were built on poor observational data, which did not stand as statistical scientific proof,” Woith said.
To better study whether animals can predict earthquakes, Woith and his colleagues suggested that researchers ask a number of yes-or-no questions in any upcoming experiments, including “Is the experimental setup and monitoring procedure clearly described and reproducible?” and “Is it proven that the animal behavior is really unusual?”
Meanwhile, humans are working on technologies that can detect earthquakes seconds before they hit. Hopefully, we will have such devices to warn people that the earthquake is coming.

5 . A study showed that farms with surrounding natural habitat experienced the most benefits from birds. The study, published in Journal of Applied Ecology, was conducted at 21 strawberry fields along California’s Central Coast. It found that birds were more likely to carry foodborne pathogens (病原体) and eat more berries without surrounding natural habitat.
The study looked at how different farming practices influenced the costs and benefits that wild birds provided on the strawberry farms. The scientists combined nearly 300 bird surveys and the tests of more than 1,000 droppings’ samples from 55 bird species to determine which birds ate pests, beneficial insects and crops, and carried foodborne pathogens.
They also ranked birds to see which were more likely to bring benefits or costs to farmlands. Barn swallows, for instance, got a “gold star” in the study. Their mud nests are commonly seen attached to the underside of eaves (屋檐), from which they fly out to fields, searching for insects.
Rather than result in a list of “good” and “bad” birds, the study found that most bird species brought both costs and benefits to farms, depending on how the landscape was managed. The presence of natural habitat was the single most important driver differentiating a farm where wild birds brought more benefits than harm.
Growers will tell you it’s impossible to keep birds off your farm—you can’t do that and don't want to from a conservation perspective. “Nature is messy, and birds are complex,” the researcher said. “The best we can do is understand how to take advantage of the benefits while reducing the harm.”
A related study in 2020 found that farms with natural habitat attracted more insect-eating birds and fewer strawberry-eating birds. Such habitats also bring greater numbers of bird species to the landscape. All together, these studies suggest that farming landscapes with natural habitat tend to be good for conservation, farmers, and public health.

It was 3 a. m. when the flood came on an unseasonably warm night in June. Rocks were heard breaking. Susan Roberts, new to Red Lodge, Montana, a small town of 2,300 people, woke from an uneasy sleep. She saw the lights on at her across-the-way neighbors’, on the side bordering Rock Creek, a 55-mile river skirting the town’s eastern edge.
Roberts’s next-door neighbor, a police officer, was evacuating (疏散) with his four kids, and he advised Roberts to do the same. So she put her dogs in the car and moved it to an narrow street behind her home, about 10 feet uphill, as her husband went from house to house, waking others. It was still dark; people were sleeping and didn’t realize. More people went to each other’s doors, saying, “Wake up and you have to get out.”
The couple stayed in their car and on the few feet of dry land surrounding it for the entirety of the next day, watching their house ruined. Trees were washed down the town’s main street. Cars floated away. Floods ruined the Beartooth Highway, a major road connecting Red Lodge to Billings. “The town looked like a riverbed,” says Roberts. “The whole community was wandering around, trying to grasp what happened.”
The day after the flood, more than 20 people friends, neighbors, strangers, even tourists flocked (群集) to help. “People went into our wet, muddy basement and pulled everything out,” says Roberts. “They sorted and took things home to wash. One person came to clean up our yard. A mother and her two young children pulled rubbish from our chain-link fence.” Helpers even saved her precious photo albums, drying each print before returning it to the book.
And volunteers kept coming every day until summer’s end. “People would not take no for an answer. If I was like, ‘Oh, we’re OK now,’ they’d be like, ‘No, I’m gonna do something,’” she says.

7 . This fall, students at the University of Massachusetts found a new menu at their canteens: the “diet for a cooler planet” menu. This meant herb-roasted lamb, raised with a carbon-friendly approach. It included sweet potatoes that had been picked from a local farm’s field. The options were plant-heavy, locally grown, and involved little or no packaging.
“We wanted to let students participate in climate action by making choices about their food” says Kathy Wicks, sustainability (可持续发展) director for UMass Dining The university is not alone in this effort. Increasingly, American consumers and institutions are thinking about how their food choices impact climate change. For many, small choices at the grocery store and restaurant can be more accessible than big-ticket options like buying a fuel-efficient car.
Small changes in eating habits may make a big difference. Studies point to the food system as a significant cause of global warming. According to Project Drawdown, a research organization that evaluates climate solutions, the way food is grown, transported, and consumed accounts for about 1/4 of the world’s greenhouse gas emissions (排放).Beef is a regular target. “If, on average, Americans cut 1/4 pound of beef per week from their diet, it’s like taking 10 million cars off the road a year,” says Sujatha Bergen, director of health campaigns for the Natural Resources Defense Council. Food waste ranks third among climate solutions. While much waste occurs before consumers are involved, Americans also throw out a lot of food they have purchased (购买) about $1, 600 worth a year per family of four.
“People are beginning to understand that their food choices have a big impact on climate,”says Megan Larnner, director of regional food at the Glynwood Center for Regional Food and Farming in New York. But she adds that substantial change will need to come from the whole food system.

10 . A new study discovers that sharks do sleep, and they often sleep with their eyes open. Since some sharks have to swim constantly to keep oxygen-rich water flowing over their gills (鱼鳃), people have long thought that they don’t sleep at all.
Researchers from Australia have now recorded a species of shark sleeping for the first time, finishing the long-standing debate about whether sharks sleep. To see if sharks were in fact asleep, the team analyzed the metabolism (新陈代谢) and pose of seven draughtsboard sharks (猫鲨) over 24 hours. When the sharks were resting for five minutes or longer, their oxygen consumption dropped, which suggested the animals were sleeping. And the researchers also noticed that the sharks changed their posture by lying flat and closer to the ground.
The sharks sometimes slept with their eyes shut as well, though, mostly during the day. At night, they tended to keep their eyes open more often, leading researchers to suspect that the sharks’ eye closure might have more to do with light than the sleep state itself. “Not only are sleeping sharks less responsive to their surroundings, but they also have lower metabolic rate,” said Michael Kelly, an ecophysiologist at La Trobe University.
“Sharks are an important group as they are the oldest living jawed vertebrates (颌类脊椎动物) — a character they share with us,” Michael Kelly said. “Sharks have been swimming in the sea for over 400 million years and have evolved very little in that time. Understanding how and why these animals sleep will provide important understanding into the function of sleep and how the animal has evolved over time.”
The team points out that more research will be needed to see if other species sleep like the draughtsboard sharks. Next they plan to continue to analyze the sharks’ brain activity while they sleep, to learn more about their waking and resting states.
