Drugs come in different forms. However,can you imagine that drugs come in chicken eggs?A team of scientists from England prove that it can come true. They have developed special chickens that lay eggs with drugs inside. These special drugs can help treat some kinds of diseases. Until now,they have made two kinds of drugs. One drug can treat skin cancer and the other can treat a nerve disease (神经性疾病).
Certain drugs are produced by the special chickens inside their egg whites. These drugs are made of proteins(蛋白质) which can be found in animals' skin,hair,milk and meat. The scientists also use DNA technology to make sure that the drugs are only inside the egg whites. In this way,the chickens can stay healthy.
Besides egg whites,drugs made of proteins come in milk of cows and sheep. Compared with cows and sheep,the special chickens have ascendancy over them. First,they are cheaper to raise. Second,they need less room and grow faster.
These special chicken can pass on their drug﹣producing ability to their children. So far,five generations (代) of the special chickens have appeared. But scientists may need more time to make the drugs perfect. It's said that scientists will realize their dream in five to ten years.

【推荐1】Beethoven wrote many famous pieces of music, but he’s probably best known for his nine symphonies. When Beethoven died in 1827, he had some ideas for a 10th Symphony(交响曲). But all that he left behind were some notes about the piece and a few “sketches” -short bits of written music.
In 2019, a special team of musicians, computer scientists, and historians was formed. Their goal: to try to complete Beethoven’s 10th Symphony with the help of AI(人工智能) to celebrate his 250th birthday. The team didn’t just want to complete the symphony, they wanted to come as close as possible to producing the symphony that Beethoven meant to write.
They fed the program all of Beethoven’s music so that the AI could look for patterns in the way Beethoven wrote. Other members of the team studied Beethoven’s notes and sketches, and figured out what Beethoven was planning to do or where in the symphony he planned to use them.
One early test told the team they were on the right track. They took a few minutes of music created by the AI based on Beethoven’s sketches, and played it for Beethoven experts, musicians, and reporters. No one could tell which parts had been written by Beethoven and which parts were made up by the AI. Finally, the AI had the challenge of connecting the little musical bits into a symphony. Last Saturday night, the piece was performed for the first time ever by the Beethoven Orchestra in Bonn, Germany.
So Beethoven now has a 10th Symphony. And though Beethoven didn’t write it all, the team feels sure that the music is very much like what he might have written, if he’d had the chance. Actually, this is the second attempt to finish Beethoven’s 10th Symphony. In 1988, musician Barry Cooper also worked on completing part of Beethoven’s 10th.
If you’re curious about what the new symphony sounds like, here is a link to an MP3 file containing a few minutes of the piece.

【推荐3】When the COVID-19 pandemic made face masks an everyday necessity, Japanese company Donut Robotics took the opportunity and created a smart mask — a high-tech upgrade to standard face coverings, designed to make communication and social distancing easier. Connected to an app, the smart mask can record the information it accepts in a written form, make the wearer’s voice louder, and translate speech into eight different languages.
Donut Robotics first developed the translation software for a robot called Cinnamon — but when the pandemic hit, the robot project was put off. That was when the team’s engineers came up with the idea to use their software in a face mask. Donut Robotics was co-founded by Taisuke no and Takafumi Okabe, aiming to change the world with small and mobile communication robots. They applied the initiative to provide services for visitors at Tokyo’s Haneda Airport. Cinnamon robot — designed to provide tourists with useful information — was one of four translation robot prototypes selected by the project.
But earlier this year, COVID-19 hit Asia and the airport project grounded to a halt. “We were running short of money and wondering how to keep the company going,” says Ono. The team sought a solution and came up with the idea to adapt its software for a product that would sell well in the pandemic. The COVID-19 pandemic led to an increase in face mask sales. Seeing an opportunity to make money with their translation technology, Donut Robotics launched a fundraiser on Japanese crowdfunding platform Fundinno in June. They raised $265, 000 in 37 minutes. “It was very surprising,” he says, “because it would usually take three or four months to get that kind of money.”
Ono says the first wave of supply is expected to take place in Japan, with 5,000 to 10,000 masks available by December, priced at $40 to $50 each. Donut Robotics will not expand overseas until April 20.

Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they’re still covered in soap. They have to ask the bathhouse worker to help them buy extra time.
“It’s a flaw in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students’ suggestions that they be allowed to pay after they’ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.
Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.
Some even used the hot water to wash their clothes. “In my experience, 10-20 minutes is enough,” said Dai Zhihua, a third-year student who usually takes 8 minutes.
A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 Yuan per minute. One male student responded by setting a record with a two-minute shower.

【推荐2】Walking along any beach in the world, you will find plastic of some kind on the shoreline, offering a reminder of the throwaway culture of the present day world. Now, a study has sounded a fresh warning on the damage caused to the marine (海洋的) ecosystem due to plastics, which eventually has an effect on human health due to the seafood we eat
In a paper titled “A Growing Plastic Smog”, researchers called on governments around the world to take firm action to handle the “plastic pollution” of the world's oceans.
The plastics break down over time into minute particles(微小颗粒) that cannot be seen by eyes, but find their way into the ocean ecosystem and into the seafood humans consume. “Microplastics are a problem because they are mistaken for food and eaten by small marine animals.” Charlene Trestrail said. “Once eaten, microplastics can damage an animal’s intestines(肠), and give out potentially harmful chemicals inside animals.”
Charlene Trestrail, a researcher at the University of Technology Sydney, said “the study shows just how big the problem is and that much of the blame was placed on the plastics industry for failing to recycle or design for recyclability.”
Paul Harvey, an environmental scientist, said “Globally, we have reached a point where we can no longer ignore the plastic pollution pandemic(流行病) that is infecting our oceans. This research shows us that beach cleanups and citizen science projects that focus on the environmental problems of plastics have little impact on solving the problem.”
Marcus Eriksen, lead author of the study, said that the findings were a “stark warning that we must act now at a global scale”. “Cleanup is useless if we continue to produce plastic at the current/rate, and we have heard about recycling for too long, while the plastic industry refuses any commitments to buy recycled material or design for recyclability. It is time for policymakers, governments and businesses to wake up and take the issue seriously.”

【推荐2】A shocking 53.6 million tons of electronic waste were discarded(丢弃)last year, a new UN-backed report has revealed. The report shows that e-waste is up 21%from five years ago. This isn't surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.
E-waste contains materials including copper(铜), iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $4 billion-worth is recovered at the moment.
While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it's often under dangerous conditions, such as burning circuit boards to recover copper, which "releases highly poisonous metals" and harms the health of workers.
The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.
But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option-the landfill.

【推荐3】The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.

Professor Hawking said,"My sister Philippa could read by the age of 4 and then she was definitely brighter than me."He said that he was unexceptional at school and was never further than halfway up his class."My classwork was very untidy,and my handwriting was the despair of my teachers,"he said."But my classmates gave me the nickname Einstein,so presumably they saw signs of something better."
But he said that it was when doctors told him that he probably only had a few years to live at the age of 21 that he was galvanized into focusing on his work and a period of productivity that resulted in some of his early breakthroughs.He said,"When you are faced with the possibility of an early death,it makes you realize that life is worth living and there are lots of things you want to do."

【推荐2】Each year, half a million people die from brain aneurysms(动脉瘤)—when a blood vessel(血管)bursts in the brain. An aneurysm is a bulge(膨胀)in a blood vessel that can burst. If that happens in the brain, it can be deadly. For survivors, physical disabilities are often severe. They may include memory problems, loss of balance, trouble speaking and even blindness. But new technologies are increasing survival rates and reducing disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is a comedian(喜剧演员). She uses humor to make others laugh. Now she’s working on a new show. Michael Alexander is her doctor. He operated on Beaumont Bacon after her attack. “She had bleeding in the frontal area of her brain, so right above the eyes. The part that was in the brain was about maybe the size of an egg. So, that’s a fairly large bleed.”
Ms. Bacon had a better chance at survival than most people because of Dr. Alexander. He directs the Neurovascular Center in Los Angeles. The center offers new technologies that include placing a catheter(导管)into an aneurysm, then threading wires to promote blood clots(血栓). This technique reduces the chances of another burst blood vessel. “You don’t have to open up the skull(头盖骨)or open up the brain to do surgery. It’s all done from inside the blood vessels. So it reduces the amount of blood loss, and the recovery is much faster.”
For Beaumont Bacon’s recovery, the hospital worked to prevent problems commonly found in patients with a burst aneurysm. The problems include brain swelling that can shut down blood vessels. She spent a month in a coma(昏迷)—unable to communicate with doctors, friends and loved ones. But with a year of treatment, she recovered. Now, she is making people laugh.
