1 . With artificial intelligence (AI) seemingly working its way into every technology out there, one area where it’s considered particularly promising is in helping doctors. And already, AI is entering some doctors’ offices.
Dr. Michael Mansour of Massachusetts General Hospital is an early user who’s helped by a form of AI that could someday change the way doctors get information. When a patient comes in with unknown infection (感染), Mansour turns to a computer program called UpToDate. It’s a common tool, with more than 2 million users at 44,000 health care organizations in over 190 countries. Basically, it’s Google for doctors — searching a huge database (数据库) of articles written by experts in the field, who are all getting information from the latest research.
Wolters Kluwer Health, the company that makes UpToDate, is trying to incorporate (整合) AI so that doctors can have more of a conversation with the database.
Some doctors hope to use AI to comb through a patient’s medical history before an appointment (预约). In some cases, Dr. June-Ho Kim, who directs a program on primary care at Ariadne Labs, says AI technology may also help primary care doctors look after patients without the help of specialists. “It will free up specialists’ time to focus on more difficult cases that they need to really home in on, rather than the ones that could be answered through a few questions,” he says.
Dr. Marc Succi, who was a co-worker of Kim, says, “AI will finally prove to be a trusted medical tool. AI won’t replace doctors, but doctors who use AI will replace doctors who do not. It will become very common just like designing a PPT on a computer. It’s that level of leap.”

4 . Artificial intelligence (AI) could help stop one of the biggest dangers to the Great Barrier Reef, amazingly saving huge areas of coral from a harmful starfish. Google has teamed with scientists from the CSIRO to create AI software that could pick out the dangerous starfish, which is one of the natural wonder’s three biggest killers.
The new way, using footage from an underwater camera to recognize starfish outbreaks on the Queensland reef, takes the place of an old method and early results show as well as cutting down man’s work, the new software has the advantage of correctly picking out more of the dangerous life on coral, stopping damaging outbreaks before they occur.
Professor Russ Babcock, an expert with CSIRO, said Google’s AI technology, developed over 18 months, could be trained to find out starfish more easily than the old method developed in the 1970s. “We used to send out divers to count the starfish one by one. Now we just look at the images collected and the program can find 20 at a time,” he said.
Google CEO Sundar Pichai said he was excited about the company’s effort put into the reef project. “We have put a lot of effort into the engineering in Australia and we will continue to do more work around AI there,” he said. “There are other good ideas about the technology and you will see us build on it. Our goal with our AI research teams is to strike partnerships with other groups, like universities and governments, to give its full play.”
Professor Babcock said the AI software, which would be put into use on other reefs worldwide, was not the only solution to the starfish affecting the Great Barrier Reef, but one that could have an wide application.

5 . Li Zixuan is a junior middle school student. He is now studying in Grade 9. He has had many dreams since he was little. But as time goes by, some new dreams have appeared and some old ones have disappeared. However, only one dream is still in his mind.
Li Zixuan says that when he was a child, he heard about rockets and spaceships. At first, he didn’t know what they were. From his father, he knew that scientists made rockets to carry things into space, and spaceships were used to carry people through space. From then on, he has had a real interest in space. Every time he sees beautiful stars and the moon in the sky at night, he gets very excited. He is always dreaming that he can fly to space to look at the earth one day. His mother knows about his dream and often encourages him.
In school, Li Zixuan learned that the first man flew into space in 1961 and later, more astronauts succeeded in traveling into space. Some astronauts even landed on the moon. His teacher always encourages him to learn more. He knows not everyone has a chance to travel into space. More importantly, before he can fly to space, he must be trained specially.
Li Zixuan knows it’s not easy to achieve his dream, but he decides to try his best. He says I’ve had this dream for many years. It has brought me a lot of joy and always gives me power. Even if it doesn’t come true in the end, I won’t be sorry.”

6 . A new test for COVID-19 is coming to store shelves throughout the U.S. This is the first test for the disease that you can do at home. It does not need a prescription, or doctor’s approval, to use.
Currently, the U.S. is testing nearly 2 million people daily, and most health experts agree the country needs to be testing many more people than that. Most tests still require a nasal swab (鼻拭子) performed by a health professional, followed by processing at a laboratory. That typically means you have to wait days for the test results.
For months, health experts have stressed the need for fast, widespread home testing, which allows people to screen themselves and avoid contact with others if they have an infection. With this new home test, people can “swab their nose, run the test and find out their results in as little as 20 minutes,” said FDA commissioner Stephen Hahn.
The test kit includes a small tool to help you to take nasal swab, or sample from inside your nose. Once you swab your nostril (鼻孔) you place the swab onto a small cartridge. This cartridge analyzes the sample and sends the results to an app on your smartphone. The app displays the results and then helps you interpret them. Users can also connect with a health professional through the app.
Ellume’s test works differently than other tests. Most tests look for the genetic material of the virus. This is the material that hakes up its genes, which influence how the virus looks and acts. However, Ellume’s test looks for proteins that the virus sheds (散发). These viral proteins are large molecules that can trigger a response from your immune system, which is the collection of cells and their responses that help the body fight off infections.
Like other COVID-19 tests that look for proteins, Ellume’s test still has a shall chance of errors. FDA officials say that people who get a negative result but still have coronavirus symptoms should follow up with a doctor.
Although the price of the test could prevent some people from using it, Dr. Michael Mina, a professor at Harvard University in Cambridge, Massachusetts, called the new test “a great addition” to existing options.

7 . China’s Yutu 2 Rover, which was crossing a crater (环形山) on the far side of the moon, discovered a mysterious, cube-like structure in November as it scanned the skyline. The unknown structure seemed to be located around 260 feet away from where the Rover crossed.
Our Space, associated with the Chinese National Space Administration which controls Yutu 2, first noted the object in a post on December 3rd; the story gave a nickname to the object “mystery hut”. Yutu 2 has since adjusted course to check out the cube, and will spend the next 2 to 3 lunar days investigating this mysterious moon feature.
The Yutu 2 Rover launched with China’s Chang’e 4 mission in 2018, and reached the moon in January 2019. The mission aimed to discover more about the far side of the moon, or as pop culture calls it, the “dark side” of the moon. Contrary to this nickname, the far side of the moon is not actually always dark, it just faces away from the Earth. The rover, solar powered, goes into a kind of hibernation (休眠) when the sun sets on the far side of the moon, and wakes up to work when the sun rises over the crater.
Yutu 2 has seen plenty of interesting moon features in its travels already, including a strange gel (胶状物) that turned out to be some rocks melted together, and some pieces that were likely to be from the impact of a meteor (流星). The Chang’e 4 mission has also brought forth some fascinating new discoveries like what could be pieces of the moon’s mantle (覆盖层).
Whatever this structure turns out to be, Yutu 2 will continue uncovering other secrets the “dark side” of the moon is holding.
