    According to the Associated Press (AP), a Chinese scientist claims he successfully created the world's first genetically-edited babies.

    Chinese researcher He Jiankui, a research professor at China's Southern University of Science and Technology in Shenzhen, said he had edited DNA of twin girls born a few weeks ago.

    He's claims were immediately criticized by some scientists as unsafe and unethical. This kind of gene editing is forbidden in the United States and many other countries. Such changes to a person's DNA can pass to future generations and risk harming other genes.

    In interviews, He Jiankui defended his work. He said he had performed the gene editing to help protect the babies from future infection of HIV, the virus responsible for the disease AIDS. He said the process had “worked safely” and the twin girls were “as healthy as any other babies.” He told the AP he felt a strong responsibility “not just to make a first, but also to make an example” for future research. “Society will decide what to do next,” he said.

    When He's claims became public, the university made a statement saying his work had “seriously went against academic ethics and standards.” University officials said they had no knowledge of his research and had looked into the case.

    China's National Health Commission was “highly concerned” about the claims and ordered local health officials “to immediately look into” He's activity. “We have to be responsible for the people's health and will act on this according to the law,” the commission said.

    Scientists discovered in recent years a new way to edit genes that make up a person's DNA throughout the body. The tool, called CRISPR-cas9, makes it possible to change DNA to supply a needed gene or take one away that is causing problems. So far the tool has only been used on adults to treat deadly diseases, and the changes only affected that person.

    Kiran Musunuru, a scientist from University of Pennsylvania, told the AP that if such an experiment had been carried out on human beings, it could not be “morally or ethically reasonable.” Julian Savulescu, a medical ethics expert at Britain's University of Oxford, agreed. “If true, this experiment may cause disasters,” he told Reuters.

    However, one well-known geneticist, Harvard University's George Church, defended the attempt to edit genes to prevent infections of HIV. He told the AP that since HIV is “a major and growing public health threat” he finds such experiments “valuable.”

    In the story of “The crow and the Pitcher” from Aesop's Fables, a thirsty crow(乌鸦) drops stones into a narrow jar to raise the low level of water inside so he can take a drink.

    Now scientists have evidence to back up that story. New Caledonian crows actually do understand how to make water displacement work to their advantage, experiments showed. The results suggest that the birds are, at least in some aspects, as smart as first-graders, according to the study.

    Researchers, led by Sarah Jelbert at the university of Auckland in New Zealand, presented six crows with tubes filled with water. Inside the tubes, a worm or piece of meat on a piece of wood was floating, just out of reach of the crow. In front of the tubes, the researchers arranged a bunch of heavy rubber erasers that would sink, and light plastic objects that would float. The crows found out that they could drop the heavy objects into the tubes in order to raise the water level and get their snack.

    However, the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow tube to get a snack, the researchers said. Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops. In contrast, it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn't realize this, and most of them went for the wide tube first.

    Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in small amount of water at the bottom.

    The summer before my dad died, we moved house. Up until that point, our family had our own space to spread out. Money was tight, so there was no television set, but we owned a turntable on which my dad's records played constantly. Mostly, it played Bob Dylan. Tracks from The Basement Tapes and Desire became an important part of our new life. My brother and I, aged 8 and 10, climbed trees, built hideaways and learned the words of Clothes Line Saga. We would chant over the, lost in our own joy.

    It was January when my dad left us forever because of the cancer. He was 36 going on 37 then, the same age as Dylan. Afterwards, our laughter disappeared, but we kept on playing the records, which became our only ritual of remembrance. The two men became so intertwined in my head, I struggled to tell them apart.

    Dylan was my dad's gift to me. What child wouldn't be fascinated by songs full of pirates and seasick sailors? How did it feel to have No direction home? Farewell, Angelina became my party-piece. I would sing this at church cheese and wines to the assembled audience. A lot of donations were made.

    Growing up, I remained a fan of the music, but I wasn't obsessed with Dylan until one day in early 1995, my brother bought us both tickets to see him play at Brixton Academy. London felt like a long way to go. But finally seeing Dylan step out onto the stage brought a sudden rush of excitement.

    I have seen Dylan a couple of times since. My brother is not around so much these days. But he was up for a visit recently. We passed a happy evening laughing and drinking, while his son, aged nine, performed his party—piece Subterranean Homesick Blues for us. He sang it word-perfect. And so it goes on: Dylan's music as a gift, passed down the generations.

    If a woman has an extra piece of cake,don 't blame it on greed, blame it on her brain.

Scientists have found that women's brains react to food very differently — and much more strongly — than men' s. Academics found that decades of dieting pressure on women and advertising have programmed certain parts of the female brain to react strongly when faced with any kind of food. Men,on the other hand, are not usually as obsessive (着迷的)about what they eat.

    Dr. Rudolf Uher and his colleagues at the Institute of Psychiatry in King's College London used brain scanning technology,known as functional magnetic resonance imaging ( FMRI),to look at the brains of eighteen men and women.

    The volunteers were given images of food to look at, as well as food to taste. Their brain reactions were observed by the scientists. They found that the female brains reacted much more strongly than those of males. The same reaction did not happen when they were shown non-food images. The team believe this means women think more about food than men tend to. Dr. Uher said, “This could be related to biological differences between men and women. But the more likely explanation is that women have a more complicated reaction to food because of social pressure. ”

Professor Carey Cooper,psychology and health professor at Lancaster University,said,“for centuries women have had a providing role — preparing and cooking food for their families. And it's part of that role to make sure the food is safe. They will therefore be much more sensitive to food than men are, and I would not be surprised if that was now built into their DNA. If the female brain react to food because it historically has developed neural (神经的)pathways to do this, then food will be the way they express their stress. Food actually,is a comfort for women. ”

    But other experts have said that more research must be done before the results can be proved. American scientist Angelo del Parigi of the John B. Pierce Laboratory in New Haven, Connecticut, said, “Looking at an FMRI alone cannot make sure whether the stronger reaction in women is due to innate (天生的)differences or a learned process. ''

    Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, "Take the extra minute to do it right. "I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those "if only "moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had lost an opportunity to say "I love you" or "I forgive you". When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be there. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only "about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality (不测的事) . And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I' m doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    At the age of 14, James Harrison had a major chest operation and he required 13 units (3.4 gallons) of blood afterwards. The blood donations saved his life, and he decided that once he turned 18, he would begin donating blood as regularly as he could.

    More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody(抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison's blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.

    "Every bottle of anti-D ever made in Australia has James in it," Robyn Barlow, the Rh program director told the Sydney Morning Herald. "It's an amazing thing. He has saved millions of babies. I cry just thinking about it." Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. He's made 1,162 donations from his right arm and 10 from his left.

    "I'd keep going if they let me," Harrison told the Herald. His doctors said it was time to stop the donations — and they certainly don't take them lightly. They had already extended the age limit for blood donations for him, and they're cutting him off now to protect his health. He made his final donation surrounded by some of the mothers and babies who his blood helped save.

    Harrison's retirement is a blow to the Rh treatment program in Australia. Only 160 donors support the program, and finding new donors has proven to be difficult. But Harrison's retirement from giving blood doesn't mean he's completely out of the game. Scientists are collecting and cataloging his DNA to create a library of antibodies and white blood cells that could be the future of the anti-D program in Australia.

    For most of her life, Suanne Laqueur's passion for storytelling was shown on the dance floor.

    Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother's dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: "Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn't want to own it."

    Yet Laqueur's disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

    Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Goodreads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer's Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

    "You have to write the most truthful story to you, and I think self-publishing allows that freedom,' she says. "If you work with traditional publishing, it's more about what's marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I'm cool with that."
