The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

    As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

    Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

    The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

    To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

    Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that can be cheaply extracted, especially in countries that can't afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

    The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

    "To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

    Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

Cara Jumper loves the giant saltwater pond on her grandparents Swansea, South Carolina, property(房产). One January afternoon, her grandfather Coy Jumper piled ten-year-old Cara and her sister, Claire, six, and Emma, five, into his Pontiac Sunfire and took them down to the pond. He and the girls walked happily through the pines, checking traps. No luck—they were empty.

    As the sun disappeared gradually toward the horizon, the group turned back to head home. But as Coy walked along the bank, he was suddenly unable to put one foot in front of the other. Then Cara saw Coy walk unsteadily and fall backward into the pond's deep water.

    When her grandfather didn't surface immediately, Cara jumped in. With one hand, Cara grabbed the bank. With the other, she reached for her grandfather, making contact in the dark water.

    Coy had suffered a stroke(中风) the year before. Now Cara wondered if he'd had one again. Just 80 pounds to her grandfather's 230, she held his head and pulled his face out of the water. That woke him, but he was still dead weight. She managed to move Coy towards the three-foot bank and pulled him up onto solid ground.

    The winter sun had almost disappeared, and they were all trembling. Cara knew she'd have to get Coy to the car, a quarter mile away. She helped him to his feet. Coy slowly moved forward.

    Sixty feet from the car, Coy fell. From there, he crawled, dragging himself under a gate, to the car. His granddaughters helped him into the passenger's side, and Cara got into the driver's seat.

"I used to sit on my dad's lap and drive," she says now. Coy, too, she says, had let the fifth grader drive through the fields around the house. Still, she felt nervous, but she pushed on the gas and steered(驾驶) them the three miles home. "I was trying to get there fast, but I didn't want to get us hurt," Cara says. When she pulled the Sunfire into the garage, her grandmother, Esca was there to meet them.

Coy spent six days in the hospital recovering from a stroke. Says Esca, "If Cara hadn't helped, she might not have a grandpa anymore."

    Are you looking for some new and exciting places to take your kids to? Try some of these places:

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from Dinosaur (恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet (木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

    It's Friday night. You're looking through your Instagram (a photo-sharing app) feed when you see it: a photo of your friends hanging out without you.

    Why didn't anyone invite you? What are they doing later? Should you text them? What if no one responds (回应)?

    Sounds like a typical case of FOMO.

    FOMO, or "fear of missing out", is a form of anxiety that causes people to feel like they're missing out on something. The word was added to The Oxford English Dictionary last year. But just how serious is FOMO?

    According to a study by a US research organization, JWTIntelligence, 47 percent of teen millennials (those who are 13-17 years old now) feel upset or nervous when they learn that their friends are doing something they're not. And 41 percent said they spread themselves too thin, trying to do too many things at one time to avoid FOMO.

    Today's technology is a big cause of FOMO, according to Jonathan Pochyly, an adolescent psychiatrist (青少年精神病学专家) at Lurie Children's Hospital in Chicago.

    "Technology is one of the things that makes life special for adolescents these days," he explained.  

    "There's a lot of focus on what everyone else is doing. It became a trend, so there's pressure to keep up with it."

    As social media (社交媒体) feeds are always updating us with our friends' activities, it's easier than ever to feel left out. So what can we do?

    To fight against FOMO, Jones freshman Emmy Brewer just calls people and talks to them.

    "I'd be upset for a bit, but then I'd realize that I should be reaching out to them," she said.

    Oak Park and River Forest High School senior James Cullinane said he fights off FOMO by living in the now.

    "If I'm hanging out with my friends, or just sitting at home on my couch, I think it's best to stay off social media and focus on what I'm doing in the moment," Cullinane said.

    While FOMO will continue to affect (影响) teenagers in the future, Pochyly said that he believes these feelings are just side effects of growing up.

    "These types of interactions (交往) with people are … a function (功能) of kids being more independent, looking for connections with other people, moving away from just being a child in a home, and moving toward adulthood," he said.

    The popular wisdom for years has been that drinking in moderation (适度)—that's one “standard” drink a day for women and two for men-is linked to a lower risk of cardiovascular (心血管的) disease. But recent studies are casting some doubt on that long-held learning. Science now says it depends on your age and drinking habits.

    A 2017 study of nearly 2 million British with no cardiovascular risk found that there was still a modest benefit in moderate drinking, especially for women over 55 who drank five drinks a week. Why that age? Alcohol can influence the substance in the blood in positive ways, experts say, and that's about the age when heart problems begin to occur.

    Also, a 2018 study found that drinking more than 100 grams of alcohol per week—equal to roughly seven standard drinks in the United States or five to six glasses of wine in the UK—increases your risk of death from all causes and in turn lowers your life expectancy. Links were found with different forms of cardiovascular disease, with people who drank more than 100 grams per week having a higher risk of stroke, heart failure.

    Another 2018 study found that consistently drinking a moderate amount of alcohol, within recommended guidelines, had a protective effect on the heart over time. Unstable drinking habits were associated with a higher risk of heart disease, which the authors reflected might indicate broader lifestyle changes, such as poor health or stress. Former drinkers were also at greater risk.

    Overall, however, the latest thinking is that any heart benefit may be outweighed by other health risks, such as high blood pressure, certain cancers and liver damage.

Women who drink are at a higher risk for breast cancer; alcohol contributes about 6% of the overall risk, possibly because it raises certain dangerous hormones in the blood. Drinking can also increase the chance you might develop liver, mouth and oral cancers. One potential reason: Alcohol weakens our immune systems, making us more likely to inflame (发炎)—a driving force behind cancer.

    One day an old woman was traveling alone in the mountains. Suddenly she saw something shining in the stream. When she came close, she found it was a precious stone. She put the stone into her bag and went on with her trip.

    The next day the old woman met a young man, who was also a traveler in the mountains. The young man looked very hungry, so the old woman opened her bag to share her food. The hungry traveler saw the precious stone and asked carefully, "The stone is beautiful. Would you like to give it to me?"

    "Sure. Why not?" the woman said, and handed the stone to him.

    The young man left happily with the stone. He knew it was worth enough to give him security for a lifetime. But a few days later he came back to return the stone to the woman.

    "I've been thinking," he said. "I know how valuable the stone is, but I give it back and hope that you can give me something even more precious. Give me what you have within your bag."

    The woman opened her bag. It was almost empty. She looked at the young man and smiled, "I have nothing special in my bag, but I do have something precious — the joy of giving!"

    The young man felt ashamed and left silently.
