2 . In a study in the journal Science, researchers at Northwestern University in Illinois reported that they had developed an effective and inexpensive method for breaking down chemicals called poly fluoro alkyl substances (PFAS).
PFAS, first created in the 1930s, are chemical compounds (化合物). They are used to make a wide range of everyday products, including nonstick pans, carpeting, electronics, and fast-food wrappers. Once the chemicals are in the environment, they are almost impossible to eliminate because they are designed to avoid breaking down. Researchers have linked regular levels of exposure to these chemicals with several health problems, including liver damage, an increased risk of cancer, and reduced immunity.
Scientists had previously figured out how to remove PFAS from polluted water or soil but, until now, had no safe and effective way to destroy them once they were removed. The study reported that when the team boiled PFAS molecules (分子) with two common substances, the PFAS quickly broke down and became harmless.
In 2020, William Dichtel, a chemist and professor at Northwestern, read a study in which chemists at the University of Alberta, in Canada, found an easy way to break down chains of molecules. He asked a graduate student, Brittany Trang, to try the method on PFAS molecules.
Trang had spent months in the lab unsuccessfully attempting to pull apart PFAS, and at first she thought Dichtel’s idea was too simple to work. But she tried it, boiling PFAS with a common solvent (溶剂) called dimethyl sulfoxide (DMSO). Trang was shocked when the process destroyed the PFAS. She later mixed DMSO with a chemical called sodiumhydroxide and broke down PFAS even more quickly.
The scientists will work on ways to destroy PFAS outside the lab so large amounts of forever chemicals can be broken down at once. “It’s a huge challenge, but it’s in our grasp,” Dichtel told The New York Times. Scientists are also calling for a decrease in the amount of PFAS being released into the natural world. In June, the US government announced new plans to monitor PFAS, decrease the amount released into the environment, and address the effects of PFAS on human health.

3 . Why did humans evolve to walk upright? Perhaps because it’s just plain easier. Make that “energetically less costly,” in science-speak.
Bipedalism — walking on two feet — is one of the defining characteristics of being human, and scientists have debated for years how it came about. In the latest attempt to find an explanation, researchers trained five chimpanzees to walk on treadmill while wearing masks that allowed measurement of their oxygen consumption. The chimps were measured both while walking upright and while moving on their legs and knuckles. That measurement of the energy needed to move round was compared with similar tests on humans and the results are published in this week’s online edition of Proceedings of the National Academy of Sciences.
It turns out that humans walking on two legs use only one quarter of the energy that chimpanzees use while knuckle-walking on four limbs. And the chimps, on average, use as much energy using two legs as they did when they used all four limbs.
However, there were differences among chimpanzees in how much energy they used, and this difference corresponded to their different gaits and anatomy. One of the chimps used less energy on two legs, one used about the same and the others used more, said David Raichlen, assistant professor of anthropology at the University of Arizona.
“What we were surprised at was the variation,” he said in telephone interview. “That was pretty exciting, because when you talk about how evolution works, variation is the bottom line, without variation there is no evolution.”
Walking, on two legs freed our arms, opening the door to manipulating the world, Raichlen said. “We think about the evolution of bipedalism as one of first events that led hominids down the path to being human.”
The research was supported by the National Science Foundation and the L. S. B. Leakey Foundation.

7 . In order to kill time, many people have been trying to cope with the boredom by reading books, others have perfected their cooking skills and many others have tried their hands at craft projects, including tie dyeing (扎染).
Whether you think tie-dye is totally stylish or not your style, the unique print from the 1960s is back in a major way. It’s become a hot fashion trend.
“The last several years have seen the resurgence in craftsmanship and handmade goods, popularizing the hobbies in the 1960s (weaving, tie-dyeing), but in a modern way. People would connect with these handmade objects to feel connected to nature,” Stitch Fix color expert Ryen Anderson said to Today. Online searches for “how to crumple (压皱) tie-dye”, a popular technique, are u by 376 percent on Pinterest.
This homestyle creation can easily be made at home. The only things we need to prepare include fabric. light-colored clothes, dye, rubber, and water. In tie-dye, the fabric is colored by tying several parts of the fabric before dying to give certain color effects. While this seems relatively simple, it takes multiple steps and washes.
Some people make tie-dye adjust old-fabrics in an innovative way. Some others use tie-dye technique to create a new pattern as the color of their clothes fades. The typical current trend is that people use natural coloring for tie-dye and combine it with doodles (涂鸦) and natural printing ( eco-printing) by abstracting colors from the leaves.
The dyeing technique has deep roots from Africa. Many immigrants from various African countries brought their skills to the United States during the 1700s to 1800s. The popularity of tie-dye then was quite influential in the 1960s or commonly referred to as “flower power” generation. Tie-dye became a symbol in that times.

During the winter time, the northern Italy is relatively cold and accompanied by heavy snows. Many people will stay indoors. But it is highly recommended to go skiing and enjoy the snow-covered landscape of the mountains. The southern and island areas are relatively warm, with an average temperature of about 15℃.
Generally speaking, the best time to take Italy tours is spring from April to June and autumn from September to October.

9 . Never Let Me Go is a novel by British author Sir Kazuo Ishiguro. It combines science fiction, horror, and coming-of-age elements in a beautiful but cruel story, which deals with the power of friendship, the pains of growing up, and self-sacrifice in the face of a cruel situation.
The book centers on Tommy, Ruth, and Kathy, who tells the story. It describes their childhood at a strange boarding school called Hailsham House, where the children all have excellent medical care but a very low quality of life. The students and teachers also act very strangely. A frightening reality is revealed: The students are all “donors”—clones of other people—who were created to donate their organs once they grow up.
The novel Never Let Me Go is not the only one by Sir Kazuo Ishiguro. He has also written six other novels, a number of short stories, four screenplays, and a handful of song lyrics. His moving words are highly regarded by both readers and critics. He has been nominated (提名) for the well-known Man Booker Prize four times, and he won in 1989 with his novel, The Remains of the Day. In 2017, he won the Nobel Prize in Literature.
Though Ishiguro has written screenplays, he was not the one who adapted Never Let Me Go into a film. The film version was released in 2010 and still stayed true to the novel. Carey Mulligan, Keira Knightley, and Andrew Garfield played Kathy, Ruth, and Tommy. I was on the whole a success with critics and was well-liked at film festivals around the world. The movie version, however, could not live up to the book in the end. Although audiences generally praised the movie and the actors’ performances, the film version did not reach the same level of success as the novel.
