2 . A brown leather cap, worn by pioneer pilot Amelia Earhart during her record-breaking flight across the Atlantic Ocean in 1928, had sold for $825,000 online, according to the Heritage Auctions (拍卖) website. The leather cap was expected to sell at around $80,000, but on Saturday, a person purchased it at about ten times the amount.

Anthony Twiggs, a retired photographer in Minnesota, put the helmet up for auction after experts confirmed its authenticity, according to The New York Times. Twiggs had received the cap 20 years ago from his mother, Ellie Brookhart, who claimed she got from a friend in 1929 following the first Women’s National Air Derby, an all-female race, in which Amelia finished third.

When the pilot was talking with reporters after the race, Ellie Brookhart and her friend were among the greeting crowd. The friend spotted the cap on the ground and presented the leather helmet—with the name “A. Earhart” printed on the inside—to Twiggs’ mother in an attempt to impress her. “My mother decided to keep it for Amelia,” Twiggs tells The New York Times. But Amelia was too busy with reporters then and when his mother tried to give it back to her a bit later, she had already left.

For the next 90 years, the cap was kept in a closet in Brookhart’s home, where she would bring it out occasionally over the years to show her four children. After his mother’s death, Twiggs tried to interest museums and collectors in acquiring it. However, he hit a wall. No one believed the story.

Now 67, Twiggs sent photos to John Robinson of Resolution Photomatching to verify (核实) the flying cap’s authenticity. After comparing images of Earhart wearing the hat with the current photos of the artifact, Robinson gave him a positive answer.

6 . People use laughter to connect and bond with others. It’s how we tell friends that we find their jokes funny, or how kids in a park show that they are having fun. Laughter is so important to humans, even if they belong to different cultures or speak different languages. What about animals? Scientists are studying if there is a connection between animals’ laughing and playing.

Sasha Winkler, from the University of California, Los Angeles (UCLA), studies biological anthropology (人类学)，including the study of animal behavior. She noticed that the small monkeys she worked with, liked to play together by chasing each other. While having fun together, they made panting (喘气) sounds, almost like they were out of breath, which reminded Winkler of their quiet laughter. This made Winkler wonder whether other animals did so while they were playing.

To find out whether other animals laugh and play, Winkler teamed up with another scientist named Greg Bryant, a professor and vice chair in the Department of Communication at UCLA. Together, they found and read dozens of reports written by other scientists who study animals. Winkler and Bryant looked for any mentions in any animal of sound signaling like the panting of the monkeys during their playing.

In April 2021, Winkler and Bryant published their findings in a science journal. Through their research, they identified 65 species or groups of animals, which laugh while playing. The animals that laugh the most include primates (灵长类) like monkeys and apes, rodents (啮齿动物) like rats, and mammals that live in the ocean like dolphins. Their work won’t only help us understand animals better but it could also help us understand how humans develop or change over time. Next, they will carry on more study to find more.

8 . The Curb-cut Effect (路缘坡效应) refers to the fact that supporting small groups of people often ends up helping much larger ranges of society.

Curb cuts: Easing the walking

In the 1940s, hundreds of thousands of World War Ⅱ soldiers returned home with disabilities. Disappointed by the difficulties they faced, Jack Fisher of Kalamazoo, Michigan, as one of them, asked his city government to build an experimental curb cut-a gentle slope that brings the end of a sidewalk down to meet the level of the street-at the corners of several blocks downtown. A few months later, Fisher reported that even residents without wheelchairs were enjoying the impact of the little slopes.

Reading machines: Getting the message

In 1976, technologist Ray Kurzweil invented a machine for the blind and visually damaged to change images into text that it then read aloud. Smart speakers with those voices are now in roughly one-quarter of US homes. By detecting street signs and house numbers, it is helping build the maps that self-driving cars use to navigate the world.

Closed captions (字幕): Following the conversation

Sears launched the first TV with a built-in equipment that allowed deaf and hard-of-hearing viewers to read along with their favorite programs in 1980. In the 1990s, text became increasingly common as DVDs and, later, streaming services added the ability to switch the words on at will. A 2006 survey found that only around 20 percent of the people using captions had hearing problems.

DeafSpace designs: Keeping things quiet

More than 150 designs of the DeafSpace Project came from architect Hansel Bauman. One aim is to clear distracting noises, which can make it difficult for people to use their limited hearing abilities. By keeping conversations and other sound disturbances from walking and jumping around the room, these ways also make it easier for all sorts of students and workers to focus.
