2 . Americans are now allowed to get a COVID-19 vaccine （疫苗）. But the process in America is not going as smoothly as some had hoped. Many people are still facing a wait for their first shot. Moreover, the vaccines aren't available to kids under 16 yet. That's because scientists have only tested if the vaccine works in adults.
The good news is that there are two companies, Moderna and Pfizer, making COVID-19 vaccines. They are now running clinical trials（临床实验）to test their vaccines in teens and kids. Volunteers are given a treatment plan and then evaluated after.
Clinical trials are designed with safety in mind and usually done in adults first. They work like this: volunteers get placed into one of two groups. One group receives the vaccine. The other group gets a placebo. This is a shot given in the same way as the vaccine but with no effect. Scientists can compare the effects of the real vaccine against the placebo to see if the vaccine works. Researchers want to know everything that a person experiences when they get the shot, so they can detect any harmful effects. If anything did happen, the trial would stop immediately.
Some teens are eager to volunteer because they want to help people. Maybe you're the right age to be part of a clinical trial for the COVID-19 vaccine. Why not volunteer For A Vaccine Trial? Interested kids should read about the trials because every trial has risks. They should talk to their doctor and weigh the benefits and risks. Every vaccine has rare side effects in a few patients.
If you want to participate in a trial, you can try to sign up online by just clicking here, clinicaltrials gov. which lists every clinical trial in the US, including COVID-19 vaccine trials.

3 . Sharks are amazing creatures. They are known as the deadliest hunters in the sea. Fortunately most are not, but there are some kinds of sharks that can be extremely dangerous. Look at these short descriptions of four kinds of sharks.
The Great White Shark
Great Whites are one of the most frightening creatures in the sea. They live in tropical and subtropical waters, and they can grow up to 9 meters long. Most Great Whites are actually grey, blue or brown with a white belly, and their powerful teeth are triangles with edges like saws.
The Whale Shark
Whale Sharks are the largest kind of shark in the world-up to 11 meters in length. They live in tropical waters all around the world, but they are not dangerous. Whale Sharks are brown or grey with white or yellow stripes. They often travel near the surface of the sea.
The Mako Shark
Mako Sharks are fierce predators. They come from the same family of sharks as the Great White and they are especially fast-they can swim at speeds of up to 65 kilometers per hour. They are large bluish sharks found in the Atlantic, Pacific and Indian oceans. Mako Sharks can grow up to 3 meters long.
The Great Hammerhead Shark
The Great Hammerheads' most striking feature is its wide thick head which looks like a hammer. The average size of a Great Hammerhead is approximately 3.5 meters, but can grow up to 6 meters long. These sharks average over 500 pounds but can weigh as much as 1,000 pounds. Like most sharks the females are larger than the males. They have several rows of teeth that have 24 to 37 teeth per row. The Great Hammerhead has a very keen sense of smell, which helps find its prey.

5 . The first known dress, as well as the earliest known bar and restaurant in France, were identified this week. The discoveries, reported in the journal Antiquity, provide a glimpse of what early life was like in both ancient Egypt and southern France thousands of years ago.
The garment, which dates to around 3482 BC, is known as the Tarkhan Dress, and now looks like a shabby and dirty shirt. When new, however, the linen dress would have looked fashionable even today, as researchers determined it featured a natural pale gray stripe with pleated sleeves and bodice. Its edge is missing, so the original length of the dress is unknown.
"The survival of highly perishable textiles（纺织品）in the archaeological record is exceptional（例外的）, the survival of complete, or almost complete, articles of clothing like the Tarkhan Dress is even more remarkable," Alice Stevenson, head of the University College London（UCL）Petrie Museum of Egyptian Archaeology, said in a press release.
Now that the dress' age has been confirmed, it has been named Egypt's oldest garment and is the oldest known surviving woven garment in the world. To calculate its age. Michael Dee of the University of Oxford and colleagues measured a small Sample of the dress to determine how much radiocarbon remained in the linen. Linen is especially suitable for radiocarbon dating, according to the researchers, because it is made of flax fibers that grow over a relatively short time. The dress, currently on display at the UCI.
Petrie Museum of Egyptian Archaeology, features wear and tear that date back to its earliest days. The researchers believe that a young teenager or a very slim woman wore it.
A separate study in the same journal reports the discovery of a hotel in southern France. At first the researcher thought that they had found a bakery, since they determined that the site once featured three huge ovens. They later, however, found that another nearby room across from a courtyard, had furniture lining its walls.

6 . Canadian-Iranian designer Roya Aghighi wants you to imagine that your shirt is alive. Aghighi hopes we can develop a more close relationship with fashion-by treating clothes as living beings that need our help to survive.
Aghighi's thought experiment isn't as far-fetched as it might seem. Working with a group of scientists at the University of British Columbia(UBC), she has invented a living, biofabricated photosynthesizing(生物制造光合作用的)fabric, which purifies the air around it. She named it LivingC.
UBC claims it's the first living and photosynthesizing fabric, and has fashioned the material into transparent clothing. While clothing like these are still in the early stages of research and design, and far from mass production, they challenge the fashion industry to reimagine ways it can reduce its huge carbon footprint through alternative fabrics.
Fashion is one of the world's most polluting industries. It's responsible for more carbon emissions than international flights and shipping combined, amounting to 10% of all greenhouse gases emitted globally.
US consumers are buying more clothing than ever, wearing each item fewer times and sending almost 70% of the clothes and footwear produced each year to landfill, according to the US Environmental Protection Agency.
While Aghighi's new and advanced clothing is now only at the proof-of-concept stage, buyers may one day be instructed to stretch the fabric out in front of a window before putting it on. Biotechnology is a big business. Beyond the world of fashion, it's seen as an alternative for polyurethane plastics—the world's most common plastic, which is used in everything from bags to outdoor furniture as well as in fabrics.
Aghighi predicts consumption habits will take a long time to change. "It is going to be a slow shift," she said. "But I hope that it's going to be a long lasting one."

7 . Although we spend one-third of our lives in bed, we hardly ever think about beds. While we may consider them little more than a mattress(床垫), pillow and blanket, they in fact have a fascinating history.
The first beds were hollows(坑洼) dug in cave floors by our African ancestors around 77,000 years ago. The basic idea of the bed and its structure have remained the same for thousands of years. Malta and Egypt were using raised frames with mattresses 5,000 years ago, according to Brian Fagan, the author of What We did in Bed. Early Egyptian beds consisted of wooden frames with legs and a leather sleeping platform. The mattress was little more than a sack(袋子) with grass, straw and hay in it. In Mongolia and China, heated stone platforms called kang were used in inns as early as 5000 BC.
The basic idea of who slept in the bed, however, has changed a lot through the years. Many family members or friends sleeping together in a single bed used to be completely normal for much of human history. Travelers would not expect privacy at inns. In fact, they had to share a bed with complete strangers. The greatest example of this was the Great Bed of Ware, a huge bed built in 1590 for an English inn. “A total of 52 people—are said to have spent a night in the Great Bed in 1689,” according to Fagan.
Throughout the 19th century, beds gradually became a private space. Rapid urbanization during the Industrial Revolution sped up this process as compact row houses were built with small rooms, each for a different purpose, including sleeping. So the next time you head to bed, be thankful you have your own.

8 . Most online fraud(诈骗) involves identity theft Passwords help. But many can be guessed. Newer phones, tablets, laptops and desktop computers often have strengthened security with fingerprint and facial recognition. But these can be imitated. That is why a new approach, behavioural biometrics(行为生物识别) is gaining ground.
It relies on the wealth of measurements made by today’s devices. These include data from sensors that reveal how people hold their phones when using them, how they carry them and even the way they walk. Touchscreens, keyboards and mice can be monitored(监测) to show the distinctive ways in which someone’s fingers and hands move. These features can then be used to determine whether someone attempting to make a deal is likely to be the device’s habitual user.
“Behavioural biometrics make it possible to identify an individual’s unique motion fingerprint”, says John Whaley, head of Unifyid, a firm in Silicon Valley that is involved in the field. When coupled with information about a user’s finger pressure and speed on the touchscreen, as well as a device’s regular places of use—as revealed by its GPS unit—that user’s identity can be pretty well determined.
Used wisely, behavioural biometrics could be a great benefit. In fact, Unifyid and an unnamed car company are even developing a system that unlocks the doors of a vehicle once the pace of the driver, as measured by his phone, is recognized. Used unwisely, however, the system would become yet another electronic spy on people’s privacy, permitting complete strangers to monitor your every action, from the moment you reach for your phone in the morning, to when you throw it on the floor at night.
