Germs that can make people sick are common in the body of healthy poultry and are legally allowed to be on raw turkey and chicken. The assumption is that nobody eats their poultry raw, and that thorough cooking will kill the germ.

The do-not-wash raw poultry advice from the USDA is relatively new and perhaps hasn’t caught on because it goes against the common belief that washing makes things clean, said Chapman. Benjamin Chapman, a study author and food safety expert at North Carolina State University, said the natural tendency to wash raw poultry goes back at least decades when people relied more on visual clues to spot problems with poultry. Meanwhile, washing hands and surfaces are also important.

But food preparation is a complicated act, and germs from poultry can be spread even if it’s not washed, especially when birds are removed from packaging.

The USDA-funded study stresses that point. Researchers sprayed raw chicken with a harmless strain of E. coli (大肠杆菌) and watched volunteer cooks at test kitchens. Among those who washed their raw chicken, about a quarter ended up spreading the germ to their cabbage. But even some of those who did not wash the chicken got germs on the cabbage. And there are other opportunities for germs to survive on turkeys: melting and cooking.

To ensure a bird is thoroughly cooked, they say to use a thermometer (温度计) to check that the deepest and thickest parts of it have reached 165 degrees. Even after the meal is cooked, you aren’t out of the danger zone. To keep turkeys and other leftovers safe, experts say they should be refrigerated after two hours.

    1    According to statistics, global tea production reached approximately 5.8 million tons in 2018. It has become the most consumed beverage(饮料) in the world-after water, of course.

In order to celebrate the popular drink, the United Nations General Assembly has named “May 21”as International Tea Day.     2     You probably know that people in China use top-grade tea to show respect when receiving important guests.     3    . Making Malaysia's pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.   As an expression of Moroccan hospitality(好客)and tradition, mint tea-a mix of green tea,   spearmint leaves and sugar-is served during gatherings.

“Apart from its cultural significance, tea is also a medicine.” Tea is cold and lowers the fire, Chinese Ming Dynasty herbalist Li Shizhen once said.     4    Preventing heart disease, obesity and cancer has all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US. The love for healthy tea products continues into a new decade as it's used in moisturizers, lip balms and other beauty products.

    5     It's a social custom and also a magic medicine, a link to the past and a way of life.

A healthy diet is rich in fiber, whole grains, fresh fruits and vegetables, and omega-3 fatty acids (不饱和脂肪酸). These dietary components turn down inflammation (炎症), which can damage tissue, joints, and organs.     2     Sweets, foods made with highly refined grains, and sugar-sweetened drinks can cause sharp increases in blood sugar that can lead to early hunger. High blood sugar is linked to the development of diabetes, obesity, and even heart disease.

    3     Being physically active can improve your brain health, help manage weight, reduce the risk of disease, strengthen bones and muscles, and improve your ability to do everyday activities. Adults who sit less and do any amount of moderate-to-vigorous physical activity gain some health benefits.     4    

Finally, establish a good relationship with a primary care physician. A primary care physician is a healthcare professional who helps you manage your health. He or she is the first person you talk to when you have any medical problem that is not an emergency. If something happens to your health, a physician you know-and who knows you-is in the best position to help.     5     A good physician and patient relationship can go a long way in helping you stay healthy-and getting the care you need when you’re not feeling well.

“We really wanted to figure out the sleeping habits of people around the world. Obviously, there have been many smaller sleep studies of people in labs but we wanted to find out what sleep is like in the real world,” says Adrian Owen. “People who logged in gave us a lot of information about themselves. They told us things like which medicine they were on, how old they were, where they were and what kind of education they’d received because these are all factors that might have contributed to some of the results.”

About half of all participants reported typically sleeping less than 6.3 hours per night, about an hour less than the study’s recommended amount. One shocking fact was that most participants who slept four hours or less performed as if they were almost nine years older.

Another surprising discovery was that sleep affected all adults equally. The amount of sleep associated with highly functional cognitive behavior was the same for everyone, regardless of age. Also, the harm associated with too little, or too much, sleep did not depend on the age of the participants.

“We found that the best amount of sleep to keep your brain performing its best is 7 to 8 hours every night. We also found that people who slept more than that amount were equally harmed as those who slept too little.” says Conor Wild, Owen Lab Research Associate and the study’s lead author.

【推荐2】The Forbidden City is well known for being full of Chinese cultural and historical relics. But Masters in the Forbidden City（《我在故宫修文物》）does not just focus on the stories of the past.

Instead, the documentary movie, which came out in Chinese cinemas on Dec. 16, focuses on ordinary people-the restorers（修复者）of relics and antiquities（古董）.

The stories are told at a slow and relaxed pace, reflecting the restorers’ work. Restoration of cultural relics and antiques can be time-consuming, and sometimes boring. Yet these restorers’ patience and peace of mind are especially precious in a society where everything is changing so fast.

“If you choose this job, you have to stand hours of work sitting on a chair. You need to be quiet and get used to being quiet,” says Wang Jin, an ancient clock repair expert.

A touching part of the documentary is the spirit of craftsmanship（工艺）in the restorers. “Years of humdrum work requires not only skill, but also faith and spirit,” China Daily commented. “Looking for preciseness and perfection, devoting yourself to work, patience, endurance（忍耐）, loneliness…All these qualities come from the craftsman spirit. ”

But unlike the popular idea of serious experts who sit around being serious, the documentary shows off the enthusiasm of the restorers. They play their guitars and make jokes about each other after a long day of restoration work.

One scene that has been very popular with Internet users features a young female restorer riding a bicycle through the empty Forbidden City on a Monday. While she is doing this, a narrator says, “The last person to do this was Puyi, the last emperor of the Oing Dynasty.”

Masters in the Forbidden City has proved wrong many people’s ideas about antique restorers, allowing them to realize that they are not old, dull professors, but people in their 40s, 30s and even 20s who can be quite pleasing to the eye.

【推荐3】Scientist in Colombia have trained a team of rats to help remove landmines from the countryside. Landmines are small bombs hidden in the ground and designed to explode when someone steps on them.

When trained, the rats can smell special metals in the mines and then signal to their human team. Then why use rats for such an important job?

In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.

The rats have already been used in Tanzania, an African country with many landmines. Luisa Fernanda Mendez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. ''They even train their babies to perform their jobs, which saves us a lot of time, '' Mendez said.

Colombia has the second-highest rate (比率) of deaths from landmine accidents in the world. Last year, land mines killed 695 people—56 of whom were children. A criminal(犯罪) group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia's government. The group has placed mines all around its own bases and in many places in the countryside.

In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.

Colombian police official Erick Guzman hopes the team of rats can come to the rescue. ''These rats will be a great help, '' he said.
