【推荐1】Peanuts are among the most popular snack foods in the United States. Millions of American children are raised on peanut butter and jelly sandwiches. PB&Js, as we like to call them, are found in children’s lunchboxes around the country. Or at least they used to be.

Now, many school officials ban peanuts or any products containing peanuts from school property. About 2 percent of U.S. schoolchildren will have an allergic reaction to peanuts. And that number is growing.

People allergic to peanuts can develop skin conditions or watery eyes. Children with a peanut allergy can develop a skin condition called eczema.

Some reactions are so severe they can result in death. So far, doctors have advised parents against serving peanut-containing foods to children under the age of 3. But a 2015 British study found that waiting too long most likely is partly to blame for the peanut allergy problem.

Anthony Fauci is head of America’s National Institute of Allergy and Infectious Diseases. Dr. Fauci spoke to VOA on Skype. He notes that m Israel, people have a tradition of feeding peanuts to babies.

He says a team of experts have agreed on new guidance for U.S. pediatricians who specialize in children’s allergies.

Fauci calls giving children peanuts a way of “challenging” their bodies. He thinks it could be done safely with some boys and girls, but not with others.

Unlike some other viruses that can cause the loss of smell by directly infecting cells involved in detecting smell, the virus that causes COVID-19 spares them. Instead, the coronavirus infects surrounding support cells. To defend the body against the virus, immune cells rush to this site of infection and generate antiviral proteins, which then lead to the loss.

Approximately 80% of COVID-19 patients who had lost their sense of smell regained it without any treatment within one to four weeks. But as three months went by, patient Chris Rogers’ situation barely improved, so he started to seek out smell training therapy.

Twice a day for 10 weeks, Rogers sniffed four kinds of essential oils — rose, lemon, eucalyptus, and clove — to potentially strengthen the survival of newly formed smell-detecting cells or speed up their production and rebuild the connection between his nose and brain. To assess whether this smell therapy was effective, the doctor asked Rogers to distinguish between a number of additional smells before and after the smell training. Rogers did the therapy for 10 weeks and started noticing improvements at week six. At least five months since the smell training ended, the improvements can be more like 75%.

While scientists have recorded improvements in some individuals’ ability to smell, it has been difficult to show how much of that improvement comes from the therapy itself or natural recovery occurring over time, said Eric Holbrook, a doctor at Massachusetts Eye and Ear Hospital. “But I continue to recommend the therapy because such training could speed up the healing process. Also, it’s one of very few and often the only therapeutic options that’s available to millions of COVID-19 patients who haven’t been able to regain their sense of smell for months,” Eric Holbrook added.

Although the benefits of smell training can vary considerably among patients, depending on their starting point, “it is generally not considered harmful,” says Bradley Goldstein, a specialist studying at Duke University. “But we still need to find specific, more effective drug therapies. It’s really an unmet need.”

【推荐2】Body language is the quietest, most secret and most powerful language of all.It is said that our body movements communicate about 50% of what we really mean while words themselves only do 7%.So while your mouth is closed, just it is your body language that is saying.

When it comes to body language at the office, you may be making some big mistakes that could cause you trouble.The following are some tips on what you should not do when using body language at your office.

Don't touch your co－workers, even if it's on the back of the arm or shoulder.Many of your co－workers are not comfortable with any body contact (接触) with others.Be careful not to touch anyone at your office.

Don't avoid eye contact.Eyes can speak.Lack of eye contact means cheat, and it can also point to no safety or lack of confidence.Trust and confidence are things you will communicate to the other person if you hold eye contact 50% of the time.

Don't have a bad handshake.You're going to show your kindness at once with a firm palm (手掌) to palm handshake.Showing the palms of your hands is an amiable gesture as it shows that you have a peaceful purpose.It means acceptance, and that you're open to new ideas.Be careful of the dead fish handshake.

Don't lean (倾斜) your head while listening to others.When listening to others, you should listen to him or her carefully with your head straight.For women especially, you think you are expressing interest by leaning your head when you are listening to others, but you actually come across as if you don't understand what's going on.

【推荐3】Facial expressions are the primary way people exhibit emotion and read the feelings of others. Happiness, sadness, disgust, fear and surprise can be communicated through facial expressions alone. But when part of the face is masked, it becomes more difficult to recognize these cues.

If you cannot read someone else' s emotional state, your ability to empathize with them may be compromised. Likewise, if your own mask is hiding your emotional state, others may not be able to empathize with you. Wearing a mask can also make you feel more distracted and self-conscious, further weakening your connection to others.

Fortunately, you can regain some control over communication by working with what you have left-the eyes. If you want to increase understanding with a masked individual, you should look them in the eyes, which may be easier said than done. Eye contact generates self- consciousness, consumes extra brain power and becomes uncomfortable after only three seconds. But bear in mind, eye contact can also make you appear more intelligent and trustworthy.

You might be surprised how much information is conveyed by the body itself. For instance, when someone is happy, they stand up straighter, when they are sad, they drop their head; and when they are angry, their whole body tenses up. Learning how people use their bodies to convey emotion may help reduce the uncertainty you feel when communicating with someone in a mask.

Become aware of your own body language, too. When engaged in a conversation, you can appear more attentive by turning your body toward the individual, leaning in or nodding. To let another person know you want to start speaking , straighten your posture, or nod more frequently. Finally, he «ware that imitating the posture of another person can increase how much they like you and even agree with you.

By all means, continue the proper measures to keep yourself safe, but don't neglect your relationships as a consequence. Social distance doesn't have to mean socially distant.

A cartoon character wearing bright red shorts on video begins instructing us to do star-jumps and sit-ups around his apartment.

Pella, a research assistant at Stockholm University, is part of the Hoffice movement, which invites workers-freelancers（自由职业者）or full-time employees who can do their jobs remotely—to work at each other’s homes to increase productivity and enjoy an active social life.

Those attending Hoffice events advertised on Facebook are typically asked to work silently in 45-minute blocks, before taking short breaks together to exercise, or simply chatting over a coffee. In addition, each participant shares daily objectives with the rest of the group upon arrival, and is invited to report back on whether or not they have achieved them at the end of the day.

“Often when I am alone, I can work focused for a couple of hours but then I’m easily distracted（分心）.The help of others makes me so much more disciplined.” says Pella, who attends Hoffice events as both a guest and a host. Lunches mean networking and connecting with new contacts. “People are coming from really different areas and have different professions so there can be really interesting discussions,” he says.

The Hoffice movement has grown quickly since it was founded in 2014 by Swedish psychologist Christofer Franzen, now 37. He had been giving lectures on the benefits of collective（集体的）intelligence, but realised he was spending most of his own time working alone at his kitchen table. “I wanted to test more structured home co-working with friends in similar situations,” he says.

Franzen says that holding events in houses and apartments creates a unique atmosphere, because there’s a sense of community and desire to contribute. He’s looking for ways to expand the social value of Hoffice, by matching up members with relevant skills to share and even encouraging jobseekers to join its gatherings.

This is the very question a new information chart from Top Masters looks to answer. According to the report, ground- breaking innovations have come despite the tragic effect of epidemics throughout history. This is a timely report because people are coming up with some innovative ideas to address many of the challenges brought on by COVID-19.

As epidemics go, the Black Death of the 1300% was extremely shocking. The plague(瘟疫) as it is also known, wiped out up to 60% of the population in Europe. According to the report, it was responsible for changing the economic and social structure of Europe and the creation of a middle class.

There were other outbreaks of the plague in England later on. In 1592, London faced an outbreak that shut down theaters for six months, This led Shakespeare to start writing poetry to make a living. And it was during this time that he wrote Venus and Adonis, and The Rape of Lucre. Another plague in 1606 also closed the theatres in London, and this time Shakespeare wrote King Lear and Macbeth.

In the US, the Boston smallpox epidemic of 1721 led to the spread of variolation(天花接种) which was responsible for reducing the death rate from 14% to2%，2s well as the first steps towards vaccines.

COVID-19 is causing serious damage around the world. And although the death rate is nowhere close, the economic impact has been overwhelming. On the negative side, it has highlighted may of the shortcoming in the healthcare industry as nurses and doctors battled virus unfortunately underequipped.

With increased connectivity and technology, innovators around the world have responded by making the equipment that healthcare workers desperately need Today’s innovators are addressing ventilator(呼吸机) shortages by using 3D printers and designing simpler ventilators; companies are making washable and reusable masks; app are tracking the virus and fighting the spread of misinformation.

【推荐2】If businesses are to get those workers unwilling to go back to work to their position, finding ways to keep people who work together or meet at social gatherings between 2 to more than 2 meters will be the issue that needs handling badly. An Israeli company thinks it can help, using smart sensors hung on workplace ceilings.

PointGrab developed its technology before the pandemic to help workspace managers optimize (优化)how employees use office space. About the size of a smoke alarm, the sensors can record the exact number and location of people in buildings including offices, hotels and restaurants.

One of the company’s first clients was Deloitte, which installed the system at its flagship London office last year, PointGrab’s sensors were connected to screens in the building to show the availability of desks and shared areas in real time. PointGrab CEO Doron Shachar says it was one of a range of innovations that helped Deloitte fit 30% more people into 3% less space.

Now PointGrab has adapted the technology so the sensors can also monitor social distancing by keeping track of how far apart people are, and whether they’re traveling in one direction around a building. Workspace managers can set up alerts for when two people are closer than two meters for more than 30 seconds, for example.

The sensors have been included in the “six feet office” concept created by real estate services company Cushman & Wakefield to encourage employees to practice social distancing. They are currently being used in this way at a university in the Netherlands, and at an innovation hub in Belgium.

While the social distancing innovation is new, PointGrab has deployed more than 10, 000 sensors for workspace optimization, including in the offices of Coca-cola, Facebook and Dell.

Workers might not like the idea, but PointGrab says no images or identifying features are recorded. Instead, each employee is represented as an anonymous dot on a dashboard. “The sensor does not violate people’s privacy,” Shachar says. “ This is extremely important in the workspace.”
