When the corona virus crisis took hold in early 2020, a group of roboticists (机器人专家) saw an opportunity: Robots are     1     perfect co-workers in a pandemic. “Engineers must use the crisis” they argued in a newspaper, “to speed up the     2     of medical robots,     3     never get sick and can do the dull, dirty, and     4     work that puts human medical workers in harm’s way.” Robot helpers could take     5     temperatures and deliver drugs, for instance. This would free up human doctors and nurses to do     6     they do best: problem-solving and being empathetic (感同身受的) with patients, and skills that robots may never be able to copy.

The     7     developing relationship between humans and robots is so complex that it has developed its own field,     8     as human-robot interaction (相互作用). The primary challenge is this: It’s easy enough     9     robots to get along with humans-make them soft and give them a sense of touch-but it’s another issue entirely to train humans to get along with the machines. With Tug the hospital robot, for example, doctors and nurses learn to treat it     10     a grandparent--sweep all the obstacles of its way and help it get unstuck if you have to.

Tu Youyou and her team reviewed ancient Chinese medical texts to find traditional     1     treatments for the disease. They examined over 2000 old medical texts, and     2     280,000 plants for their medical     3    . From their research, they discovered and tested 380     4     ancient Chinese medical     5     that showed promise in the fight against malaria.

Skin, the largest organ of the body, is a barrier against toxins and rays and gives you your sense of touch. Therefore, applying first-aid     1    can avoid serious injuries from burns.

Burns are mainly caused by fire, radiation, acids, etc. There are three types of burns.

First degree burns, usually caused by     2    incidents, only affect the top few millimeters of the skin. Going below the top layer of the skin, second-degree burns often go with     3    skin blisters. Third-degree burns affect every layer of the skin. Below are some first-aid techniques for burns. Firstly, place burns under running water without     4    to ease the swelling. Secondly, dry the burnt area. Thirdly, remove clothes unless the fabric sticks to the burnt skin. Fourthly, cover the burnt area with a loose clean cloth. Fifthly, make sure the     5     can breathe.

SEATTLE-For the more than 10 million Americans with colorblindness, there’s never been a treatment, let alone a cure, for the condition that leaves them unable to distinguish curtain colors.

Now, for the first time, two University of Washington professors have teamed with a California biotech firm to develop what they say may be a     1    : a single shot in the eye that can reveal the world in full color.

Jay and Maureen Neitz, who have studied the vision disorder for years, have found a new way to deliver genes that can replace missing color-producing proteins in certain cells, called cones, in the eyes.

The trouble will     2     when people are born without one or more of the three types of color-sensing proteins normally present in the cones of the retina (视网膜). The most common type is red-green colorblindness, followed by blue-yellow colorblindness. A very small proportion of the population is     3     colorblind, seeing only shades of gray.

Colorblindness is often a/an     4     disorder. It affects mostly men, who can inherit a mutation (变异) on the X chromosome (染色体) that weakens their perception of red and green. A much smaller part of cases are in women, who have two X chromosomes, which gives them a better chance of avoiding effects of any genetic imperfection.

Most people think of colorblindness as a/an     5     or disability, mainly causing problems with unmatched shirts and socks. But the Neitzes say the condition can have profound impacts-limiting choices for education or careers, making driving dangerous, and forcing continual     6     to a world designed for color vision.

“There are an awful lot of people who feel like their life is     7     because they don’t see color,” said Jay Neitz, 61, a professor, who confirmed in 1989 that dogs are colorblind, too.

People may not     8     as commercial pilots, for instance, if they’re colorblind. Other careers that can be restricted include those of chefs, decorators, electricians and house painters, all of which     9    detailed color vision.

Undoubtedly, the Neitzes’ findings have brought great benefits to those who are born unable to distinguish between red and green. But that technique is     10    , requiring surgery, so the Neitzes are looking for another way to do the job.

British scientists believe they may have found a way to fight the common cold. It blocks a key protein in the body’s cells that is to     1     for the spread of cold-causing virus. Targeting the host rather than the infection was a bit non-traditional but made sense because it was tricky to target the virus. Cold-causing viruses are not only of     2     kinds, they also     3     rapidly, meaning they can quickly develop resistance to medicine. Researchers are working on making a form of medicine that can be taken directly into one’s lungs, to    4     the chance of side effects. Though these scientists have made     5     advances in their research, further    6     is needed to make sure such drugs are not so     7    that they harm the body.

One Medical

On Thursday, Amazon announced its first major acquisition (收购) under Mr. Jassy’s occupation as C.E.O., spending $3.9 billion for One Medical, a chain of primary care clinics around the country. The deal is a sign of Amazon’s health care ambitions. As the company has     1     from one business to another — including books, CDs, electronics, dog food and clothes — it has had to look in less obvious spots to find opportunities that can provide meaningful     2    .

Health care has been     3     to Amazon executives who believe it is an extremely large market, filled with inefficiencies and generally lacking the kind of     4     approach that Amazon tries to take with its businesses. “We think health care is high on the list of experiences that need     5    ,” Neil Lindsay, the senior vice president of Amazon Health Services, said in a statement announcing the deal. He also listed some of the     6     of modern health care: booking appointments, sitting in waiting rooms, even finding a parking spot.

Amazon wants to be the “front door” through which customers     7     health care. That One Medical sees about five times as many virtual visits as     8     appointments most likely made it attractive to Amazon. The company also has something Amazon values     9    : data. One Medical built its own electronic medical records system, and it has 15 years’ worth of medical and health-system data. While individual patient records are generally protected under federal health privacy laws, the big data skill that has     10     Amazon’s success can be powerful in health care — for predicting costs, targeting interventions and developing products and treatments.

No wonder they are called “patients”. When people enter the health-care systems of rich countries today, they know what they will get: endless tests, baffling jargon, rising costs and, above all, long waits. This week three of the biggest names in American business — Amazon, Berkshire Hathaway and JPMorgan Chase — announced a new     1     to provide better, cheaper health care for their employees. A fundamental problem with today’s system is that patients     2     knowledge and control. Access to data can bestow both.

The Internet already enables patients to     3     online consultations when and where it suits them. You can take over-the-counter tests to analyze your blood, sequence your genome and check on the bacteria in your gut. Yet radical change demands a     4     in emphasis, from providers to patients and from doctors to data. Technologies such as the smartphone allow people to     5     their own health. The possibilities     6     when you add the crucial missing ingredients — access to your own medical records and the ability to share information with those you trust. That allows you to reduce inefficiencies in your own treatment and also to provide data to help train medical algorithms (计算程序；算法). You can enhance your own care and everyone else’s too.

Medical data may not seem like the type of kindling to     7     a revolution, but the flow of information is likely to     8     fruit in several ways. One is better diagnosis. Someone worried about their heart can now buy a watch strap containing a medical-grade monitor that will     9     arrhythmias (心律不齐). APPs are competing to see if they can diagnose everything from skin cancer to Parkinson’s disease. Research is under way to see whether sweat can be analyzed for molecular biomarkers without the need for an invasive blood test. Some think that changes in how quickly a person swipes a phone’s touchscreen might     10     the onset (开端) of cognitive problems.
