1 . To study the behavior of mysterious animals, scientists routinely fix them with GPS location trackers. But such devices’ battery capacity limits how long they operate, often bringing an early end to vital conservation work.
Solar-powered trackers break easily, making them a poor choice for devices tied to larger mammals—and they don’t work for nocturnal (夜行的) creatures. So biologist Rasmus Worsoe Havmoller of the University of Copenhagen and his colleagues turned to another abundant power source: kinetic energy (动能) generated by an animal’s movements.
Their kinetic tracker, which Havmoller’s team recently tested on domestic dogs, a wild small horse and a European bison, could theoretically survive for the entire life span of an active animal. It is also lighter and cheaper to make than its battery-powered counterparts.
“The design is clever and exciting,” says Mark Hebblewhite, a habitat ecologist at the University of Montana, who was not involved with the new work. The proof-of-concept kinetic tracker works by means of a magnetic pendulum (磁摆) that swings around a copper coil, generating electricity as the tagged animal moves. The dogs and bison in the study were active enough to create the energy to transmit one location per day for 14 days and 17 days, respectively. One of the wild horse’s trackers lasted at least 146 days but didn’t generate adequate power for daily transmissions, the researchers reported in PLoS ONE.
“The limited power generated by the animals’ movements means the technology isn’t ready for prime time just yet,” says ecologist Emily Studd of British Columbia’s Thompson Rivers University, who wasn’t involved in the study. When the researchers want to monitor animals closely, they often need GPS fixes more than once a day. But Studd says that “with a bit more development, this could be a game changer for wildlife animal research and monitoring”.
Havmoller and his colleagues hope conservation workers can one day use this technology to track species such as tigers, leopards and wolves, which can easily destroy solar-powered trackers and which hunt and travel at night.

My kitchen was a mess. Clouds of flour dusted the counters, the floor, and the aprons of the women gathered there.
Peels from 40 pounds of apples were piled in the corner. Mixing bowls sticky with cinnamon and sugar tipped messily in the sink. The wrappers from 12 pounds’ worth of butter spilled from the trash. But, wow, it did smell sweet.
Six of us had gathered that Saturday morning to make apple pies. Once colleagues, now simply friends, we shared an intense curiosity about all sort s of things, and we loved to chat.
Today our curiosity and chatter were directed to pie-making. While I was no top chef, I knew how to use a rolling pin and I’d had years of practice serving up strawberry cakes, coconut cream, and sour cherry pies to my family.
Pie-making is a lot of work. Whoever coined the phrase “easy as pie” must have meant consuming, not creating. We spent hours peeling, coring, slicing, measuring, and learning to handle delicate dough (面团).
“It’s sticking to the rolling pin,” one of them said, her voice full of depression.
“Oh no, it’s cracking!” came another cry. I assured them the patched crust (皮) would simply serve as a reminder that these pies were home-made.
Outside, an October snowstorm struck heavily. Inside, though, it was all steamy windows, soft music and happy laughter as we finally put our pies into the oven.
When planning “Pie Day”, we decided that we would each make two pies: One for our families and one to donate to someone else.
By early afternoon, 12 pies had been placed on the counter, their perfectly imperfect crusts shining goldenly. We rushed to prepare for delivery, packing the pies messily in boxes and bags. We marched down the driveway. The snow had melted (融化); the roads were clear. It was time to deliver.
Then, disaster struck. One of the painstakingly crafted pies melted through the bag it was packed in and fell onto the driveway. Screams of horror followed.

6 . A number of recent studies of families in several Asian countries help to shed light on how grandparents are involved in coparenting, which researchers define as the sharing of childcare and upbringing responsibility among two or more adults. These studies suggest that children benefit when parents have strong relationships with coparenting grandparents.
Researcher Xiaowei Li and her coworkers recently explored parent-grandparent coparenting in China, where it is very common. In their 2019 study, nearly 180 mothers of preschoolers completed questionnaires (问卷调查) about their coparenting. The majority of families lived in three-generational households, and 80% of families had only one child.
The questionnaire asked about positive aspects of the parent-grandparent coparenting relationship, like how much they agreed and felt close as well as challenging aspects like how much they had conflict in front of the child. The researchers also measured how competent mothers felt in using parenting strategies and teaching their children age-appropriate skills.
The findings? Mothers who had strong coparenting relationships with grandparents tended to feel more effective in their role as a parent, and, in turn, their children tended to be more socially competent. That’s because grandparents, with their rich experience, can provide support, role modeling, and encouragement when they raise children, which could influence how competent mothers feel in their parenting role. And when mothers are feeling more confident, they can approach parenting with more positivity, which can boost their children’s social development.
Parent-grandparent coparenting also seems to influence other aspects of children’s development, such as preschoolers’ effortful control—their ability to regulate how they respond to a situation and notice novelty or mistakes. For preschoolers, it might come into play when they get a gift they don’t like, or have to figure out how to share toys.
This research on grandparents highlights that handling the coparenting relationship is not without its challenges. But grandparents’ involvement in children’s upbringing can bring great benefits for families and grandparents themselves.

8 . Getting a driving license was once a universal passage into adulthood. But now a growing minority of young people ignore or actively oppose it, into their 20s and beyond. That starts to create more support for anti-car policies in cities around the world to pass anti-car laws, changing planning rules to favour pedestrians over drivers. After a century in which the car remade the rich world, the tide begins to swing the other way.
By 1997, 43% of America’s 16-year-olds had driving licenses. But the proportion has been falling for every age group under 40. Even those who have them are driving less. A similar trend is seen in Europe. One study of five European capitals found the number of driving trips made by working people was down substantially since a peak in the 1990s.
No one is entirely sure why young adults are proving resistant to owning a car. The growth of the interest is one obvious possibility—the more you can shop online, or stream films at home, the less need there is to drive into town. The rise of taxi apps like Uber has contributed as well. Driving generally is more expensive. Other reasons seem more cultural. One big motivator is worries about climate change.
The falling popularity of cars among the under-40s chimes with the mood among city planners and urbanists. In America, New York has banned cars from Central Park and some streets. In the past few years, dozens of American cities have removed rules that force developers to provide a certain amount of free parking around their buildings.
As the example in Oxfond shows, political opposition could put the brakes on the growth of anti-car policies. But in the parts of Europe where anti-car policies have been in place, they appear to have worked. Giulio notes that almost nowhere in the world that has removed a big road, or pedestrianised a shopping street, has decided to turn back. “Once people see, they generally don’t want to go back.” If that pattern holds, the 21st century might just see the car’s high-water mark.

10 . According to Jaime Roberts, good consulting is often about loosening the body, opening the mind and, more often than not, keeping the mouth shut.
Your body language matters
Jaime Roberts has been one of my go to experts for advice for decades. When I once asked her why she was so good at consulting, she was quick to mention her body language. “
You don’t have to fix the problem
That’s another thing Jaime Roberts has learned on the job, “People who ask ‘What should I do?’ often want to process a problem themselves.
You don’t need to give advice right now
Texts and FaceTime might be immediate, but your advice doesn’t have to be.
You’re bound to hear about problems you haven’t experienced firsthand. That’s why Jaime Roberts says you should let them know that you’re just human beings with limited experience.
A.Don’t say their choices are wrong |
B.You cannot give advice as giving someone an order |
C.I try to appear relaxed and avoid looks of shock or judgment |
D.You don’t need to have the same problem to be a good consultant |
E.But you should let them know you will do your best to understand them |
F.You’re a good consultant if you can help them fix the problem on their own |
G.You can politely explain to them that you will talk to them when you’re ready |
