4 . Relatives of starfish, brittle stars (海蛇尾) spend most of their time hiding under rocks in the ocean or digging in the sand. These shy marine creatures have no brain to speak of—just nerve cords running down each of their five wiggly arms, which join to form a nerve ring near their mouth.
“There’s no processing center. Each of the nerve cords can act independently. Instead of a boss, it’s like a committee. That seems to be enough to learn by association,” said lead author Julia Notar. This type of leaning involves associating different stimuli via a process called classical conditioning (条件反射).
Classical conditioning has been demonstrated in a handful of previous studies in starfish. But brittle stars and similarly brainless starfish have not been tested.
To find out if brittle stars have the ability of learning, the researchers put 16 black brittle stars in individual water tanks and used a video camera to record their behavior. Half the brittle stars were trained by dimming the lights for 30 minutes whenever the animals were fed. Every time the lights went out, the researchers would put a bit of shrimp in the tanks, placed just out of reach. The other half got just as much shrimp and also experienced a 30-minute dark period, but never at the same time—the animals were fed under lit conditions.
Whether it was light or dark, the animals spent most of their time hiding behind the filters in their tanks, only coming out at mealtime. But only the trained brittle stars learned to associate darkness with food. They didn’t need to smell or taste the shrimp to react.
Notar said the results are exciting because classical conditioning hasn’t really been shown definitively in this group of animals before. “Knowing that brittle stars can learn means they’re not just robotic scavengers (清道夫) cleaning up the ocean floor,” Notar said. “They’re potentially able to expect and avoid predators (捕食者) or expect food because they’re learning about their environment.”

6 . Pat Patterson, a pilot for 25 years, had never met anyone like the handsome young man in the wheelchair who faced him at the Medford, Oregon, airport on July 28, 1976. Mike Henderson, a quadriplegic (四肢瘫痪者), wanted flying lessons.
As a 22-year-old Coast Guardsman eight years before, Henderson had fallen off a dock and landed on a floating log, breaking two of his bones. Doctors said that he would probably never walk again, let alone fly. “Here was this doctor telling me how it was going to be,” he says, “but no one was going to limit my freedom to try.”
Henderson parked his wheelchair next to the airplane and began to climb up onto the wing. He injured his elbow on the way, and after a great struggle, finally managed to pull himself into the airplane’s pilot’s seat. In the flight office, Pat Patterson watched in disbelief. “He crawled his way up that wing!” he says. “It took him 45 minutes. When I went out, he was sitting in the pilot’s seat, bleeding from his injured elbow all over the place. When I saw him go through that much pain, I knew nothing could stop him.”
Now everything was up to the instructor and the student, and together they set about solving each problem as it arose. A small piece of carpet gave Henderson traction (摩擦力) to climb the slippery wing. A headset freed his hands from the radio microphone, and the two men developed a moving bar that enabled Henderson to operate the airplane more easily.
Three weeks and eight flying hours after the first lesson, Henderson and Patterson happily phoned Dr. Stoddard — Henderson’s physician. At the airport, as the physician looked on, Henderson quickly wheeled himself around the airplane, doing a thorough, professional ground check. With Patterson and Dr. Stoddard on board, he went through his preflight instrument check. Minutes later, engine starting, the plane rolled down the runway and took off into the gray sky.

8 . “Few articles change owners more frequently than clothes. They travel downwards from grade to grade in the social scale with remarkable regularity,” wrote the journalist Adolphe Smith in 1877 as he traced a coat’s journey in the last century: cleaned, repaired and resold repeatedly; cut down into a smaller item; eventually recycled into new fabric. But with the improvement in people’s living standards, that model is mind-boggling in the era of fast fashion. The average British customer buys four items a month. And it is reported that 350,000 tonnes of used but still wearable clothes go to landfills in the UK each year.
Yet the gradual revival of the second-hand trade has gathered pace in the past few years. At fashion website Asos, sales of vintage clothes (古董衫) have risen by 92%. Clothing was once worn out of necessity, and now it is simply a way of life. Busy families sell used items on eBay, teenagers trade on Depop and some fashion people offer designer labels on Vestiaire Collective. Strikingly, it has become big enough business that mainstream retailers (零售商) want a slice of the action.
For some buyers and sellers, the switch to the second-hand is born of financial difficulties. Only a few have become worried about the impact of their shopping habit on the planet. But the shift is only a partial solution. Some people worry that some mainstream brands may “greenwash” — using second-hand goods to improve their image, rather than engaging more seriously with sustainability.
However, the biggest concern may be that people keep buying because they know they can resell goods, still chasing the pleasure of the next purchase but with an eased conscience (愧疚). Boohoo, a powerful fast fashion company, has seen sales and profits rise, despite concerns about environmental problems in its supply chain that led to an investigation last year.
A new Netflix series, Worn Stories, documents the emotional meanings that clothes can have: Each old item is full of memories. Actually, a handbag from a grandmother and a scarf passed on by a father are both valuable for us. A love of style is not a bad or an unimportant thing. But a committed relationship is better than a quick flash. Can we learn to appreciate our own old clothes as well as others’?

9 . Anew study reports that a mosquito’s sense of smell is more complicated than we once thought. And it may explain why this annoying insect is so good at seeking you out at a barbecue or in your bedroom and biting you—as well as lead to new strategies to prevent the potentially deadly diseases transmitted by its bite.
Meg Younger, a neuroscientist at Boston University, is co-author of the study. She exhales(呼气)gently into one of the mosquito-filled cages. A waft of carbon dioxide blows across the insects, and they go wild. “And now, they’re looking fora target like the complex mixture of human body smell—a smell that’s attractive to the mosquitoes,” Younger explains.
In many parts of the world, this attraction isn’t merely an annoyance for humans. It’s a major health problem. Mosquitoes transmit diseases to humans. These diseases include dengue, Zika, chikungunya fever and malaria. The last disease alone causes over half a million deaths each year.
So scientists have attempted to break this attraction. But try as they might, the little mosquito has resisted. “They’re really good at what they do,” Younger says. Most of what we know about the neuroscience of smell comes from mice and fruit flies, where the wiring is fairly simple. Each neuron(神经元) in the nose has one kind of receptor(感受器) that detects a single kind of smell—say, a banana. And all the neurons with receptors for the banana smell connect to the same part of the brain. Younger and the others studied mosquito brains, where she found that each neuron has multiple receptors that can detect multiple smells.
This work could give researchers additional ways to battle the insects like developing traps that contain new smell mixtures that are more appealing than people.
“It’s an enormous study,” says Josefina del Marmol, a neurobiologist at the Harvard Medical School. She says there’s more work to be done to check. neuron by neuron, that each one actually responds to all the smells it has receptors for. But regarding the central finding, she says, “It really does change a lot about what we know of how insects perceive the world.”

10 . Mary Dickins had been a member of the audience at poetry nights before and knew “the poetry clap”. She made a polite tapping of fingers. But when she made her debut (首次演出) as a performer at the age of 62 at the legendary Bang Said the Gun night in south London, she said, “It was so wild — like nothing I had ever seen before.” The audience stamped their feet and shook shakers. “It felt transformative. I thought, ‘I’ve got to have more of this,’ ” Dickins said. Becoming a performance poet has given her a place on a stage of her own making.
All her life she has written, mostly without being seen or heard. Her mother died when she was nine, and, after she went into a care home at 13, Dickins’ writing stayed in notebooks. Really, she says, a lot of her adult life has been about getting over childhood shyness. At university — she studied education — she met her husband of 40 years, but in three years of seminars she did not say a word. Some of this results from her years at the children’s home. She says, “It gave me a sense of what it’s like to be excluded. I never fitted in anywhere.”
After she graduated, she discovered that she loved working with people with learning disabilities. She became an expert in inclusive education. “That was my niche (称心的职业),” she says. She published books and returned to the University of North London as a senior lecturer in early childhood studies.
Dickins now sees that in adulthood she has been giving herself permission to be silly. “The sillier I allow myself to be, the better the writing is,” she says. Her observations are humorous.
“Putting things into words and giving shape to your emotions is an important part of coming to terms with the things that happen in life,” she says.
Does she still feel like an outsider?
“I think I’ve made it into a virtue. I celebrate the fact that I don’t fit into a box. Finally! You have to wait till you’re 62 to feel confident!” she says. “But I have a sense of who I am and I'm proud of it. I wouldn’t be anyone else now — and it took me a long time to say that.”
