5 . We’ve all been there — staring at a pile of books, desperately hoping that what we study will stick in our mind. Many of us have probably asked if there’s any way that we can get better at remembering things.
Every student who has made flashcards knows that it can be helpful to go back over what they’ve studied before. The Learning Scientists, a group of cognitive scientists, have made a new discovery.
There are also more general things that we can do to improve our memory. Hancock says that being generally organised makes things easier for your brain, while many other experts also recommend avoiding stress, alcohol and smoking, and that we should get a lot of rest and exercise.
A.We don’t know exactly why this happens. |
B.It’s important to the long-term memory. |
C.So, why don’t we look at what memory experts say about this? |
D.Another study tip is to change between different topics as you study. |
E.It could be making letter patterns into words, or by sorting things into categories. |
F.According to them, we can learn things better if we wait for some time before trying to study them again. |
G.So, while it may be hard, improving our memory is something we can control. |
6 . On Inaccessible Island, you hear the sound of the Inaccessible Island rails (秧鸡) everywhere. The small flightless birds move around, feeding on worms and berries. During a trip in 2011, it took days for Stervander, then a doctoral student, to spot one. “Even then, you see something little and dark, running for a second, and that’s about it,” he says. Catching one, though, proved easy. When scientists played a recording of the bird’s call, a male and female ran into the net a few minutes later.
Inaccessible Island rails live only on Inaccessible Island. “No one knew the history,” says Stervander, now a research fellow at the University of Oregon. He aimed to answer the question about these birds: How did they get to Inaccessible Island to begin with?
The first scientist to describe the rail was Percy Lowe. He thought the bird was from Africa and had always been flightless. In his view, it had arrived at the island by walking over land bridges. But now the science of plate tectonics (板块构造论) suggests that’s not the case. In a recent paper, Stervander and his colleagues give evidence for a different version.
After studying the genome (基因组) of the rails, scientists found the Inaccessible Island rail’s closest relative — the crake in Uruguay. Both birds are related to the black rail in America. The finding suggests the ancestors of these birds could fly. That means Inaccessible Island rails flew to their present home, and like many birds living on islands with no predators (捕食者), they gradually lost the ability to fly. Flying takes energy, so if there’s no reason to fly, it’s more practical not to.
On this island, there’s a growing population of rails, but they’re fragile. Should a predator reach the island, it could make quick work of the birds. People on nearby islands are careful to avoid introducing any predators to Inaccessible Island, and the risk is low, given how hard it is to get there. For now, the rails live peacefully in a place where few humans are eager to go.

7 . For the 70 percent of the world’s population without any chance of using electric washing machines, keeping up with laundry takes up a lot of time. And it is often a painful physical task. The task falls unreasonably to women and girls, who can spend 20 hours a week washing clothes, often without electricity or running water. London engineer Navjot Sawhney, however, has come up with an idea: a portable and lightweight washing machine that is similar to a plastic drum. It also does double duty as a dryer, and costs around $60.
31-year-old Sawhney calls it the Divya, after the woman who inspired the project — his former next-door neighbour in South India, where he spent a year volunteering after leaving his job as an engineer at high-end vacuum (真空吸尘器) maker Dyson. “When I got to know Divya, I was so sad about all the unpaid work she needed to do — cleaning clothes,” says Sawhney. In 2018, he returned to the United Kingdom to found “The Washing Machine Project”, which is developing a washing solution that will be affordable, portable and accessible for everyone, everywhere. After a few months of developing a model, he received some money from Oxfam’s Iraq Response Innovation Lab.
Since March 2019, more than 150 Divyas have been given out to refugees (难民) in Iraq through non-profit partners. “The response was great,” Sawhney says. His goal is to deliver 8,000 machines in 10 countries over the next three years. By saving 75 percent of the time and 50 percent of the water required to wash clothes, he says, women and girls will be freer to accept education.
Aside from the Divya, Sawhney has also worked on making fuel-efficient cookstoves, and plans to develop refrigerators, conditioners, and lighting. Sawhney sees the world’s growing refugee crisis as a call for innovation: “There is a huge need for appliances that make life better for people.”
