1 . Harvard University, which is facing claims of racial discrimination against Asian-Americans in its admission process, has announced that its early acceptance rate for Asian Americans for the Class of 2022 has hit 24.2 percent, up from 21.7 percent a year earlier. The figures were released on Dec 12, 2017 by the school on its official website, the Harvard Gazette.
The early enrollments for the Class of 2022 also reflect an overall increase in other nonwhite students from previous years, the famous university said. African-Americans make up 13.9 percent of students admitted early, compared with 12.6 percent last year. At the same time, Latinos account for 9.8 percent, up 1 percentage point last year, and Native Americans and Native Hawaiians account for 1.8 percent, up from 1.1 percent.
“From small towns, suburbs, and cities — from throughout the United States and around the world — the Class of 2022 promises to be among the best classes in Harvard’s long history,” said William R. Fitzsimmons, dean of admissions and financial aid at Harvard University.
Harvard is facing scrutiny from the Department of Justice and a separate lawsuit accusing the college of discriminating against Asian-Americans in its undergraduate admission process.
In November, 2017 the Justice Department cited a 2015 lawsuit that charges Harvard’s affirmative action policies discriminating against Asian-American applicants, in a letter setting a Dec 1 deadline for Harvard to hand over documents on its admission policies. Responding to that deadline, Harvard offered a compromise position in which the government’s lawyers would be able to examine all the records, including an electronic database, in the offices of Harvard’s lawyers, with some personal information redacted, according to The New York Times.
Harvard University reported that 16.6 percent of a total 29,652 students are Asian, according to college factual.com. Over the past five years, the total international population of students on campus has grown at an average rate of 6.8 percent. China is the largest contributor to this growth, with about 1,263 students.

2 . Chinese audiences on average spent more time watching entertainment content online in this uncommon year when the battle against COVID-19 is still being fought.
An average consumer has spent 133.9 minutes each day watching TV dramas, a 10 percent increase compared to last year, according to the report. Interestingly, TV romantic dramas make up 36 percent of all 131 new television series this year, ranking the first.
In the overseas market, Chinese dramas are seeing a rise in popularity, such as hit costume dramas Three Lives Three Worlds, The Pillow Book, and The Romance of Tiger and Rose. The report shows that subscribers (订阅者) of WeTV, the overseas version of Tencent Video in more than 110 countries and regions, have risen 175 percent over last year, with time spent watching these programs up 300 percent year-on-year.
Shows with strong female roles are more popular, like the hit series Nothing but Thirty, I Will Find You a Better Home and A Murderous Affair in Horizon Tower, the report said. It also found that a quality trailer (预告片) played an important role in drawing an audience, as about 90 percent of consumers pick their choices from trailers.
As a result of the six-month shutting down of Chinese cinemas, a number of people have chosen watching films online.
Through Nov. 30, a total of 15 online films have earned more than 10 million yuan, propelling the annual box office income on Tencent Video to nearly 500 million yuan this year. While TV series are almost "dominated" by female audiences, men are favored online movies more. Nearly 70 percent of online film viewers are men, whose favorite themes center on fantasy, comedy and adventure.

3 . Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases---clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived (复活). Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism, cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seize d the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.

4 . In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scolds her unattractive assistant for imagining that high fashion doesn’t affect her, Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to departments stores and to the bargain bin in which the poor girl doubtless found her garment.
This top-down conception of the fashion business couldn’t be more out of date or at odds with the feverish world described in Overdressed, Elizabeth Cline’s three-year indictment of “fast fashion”. In the last decade or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quicker turnarounds mean less wasted inventory, more frequent release, and more profit. These labels encourage style-conscious consumers to see clothes as disposable-meant to last only a wash or two, although they don’t advertise that-and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking an industry long accustomed to a seasonal pace.
The victims of this revolution, of course, are not limited to designers. For H&M to offer a $5.95 knit miniskirt in all its 2,300-plus stores around the world, it must rely on low-wage overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.
Overdressed is the fashion world’s answer to consumer-activist bestsellers like Michael Pollan’s The Omnivore’s Dilemma. “Mass-produced clothing, like fast food, fills a hunger and need, yet is non-durable and wasteful,” Cline argues. Americans, she finds, buy roughly 20 billion garments a year—about 64 items per person—and no matter how much they give away, this excess leads to waste.
Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named Sarah Kate Beaumont, who since 2008 has made all of her own clothes-and beautifully. But as Cline is the first to note, it took Beaumont decades to perfect her craft; her example can’t be knocked off.
Though several fast-fashion companies have made efforts to curb their impact on labor and the environment—including H&M, with its green Conscious Collection line—Cline believes lasting change can only be affected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can’t afford not to.

5 . A new study has found that animals feign（假装）death for long periods of time in order to escape capture from their predators. How long they are motionless depends on the circumstances, but they can wait out their predators for quite a long time when their lives are in danger.
Animals stay still to avoid capture for different lengths of time. “Most intriguingly, Charles Darwin recorded a beetle that remained motionless for 23 minutes. Antlions, our favorite study creature in this regard, set a record of 61 minutes,” says lead author Nigel R. Franks from the University of Bristol.
Antlions are members of large group of insects. Antlion larvae（幼虫）dig pits in loose soil and then aggressively attack ants and other small insects that fall into the sandy pits. In another study, researchers dug sandpits to understand the physics of how antlion larvae build their pits. As part of their research they needed to weigh the individual larvae. When they put them onto the microbalance scale to weigh them, they noticed that the larvae remained motionless for long periods of time. “This made it ‘piece of cake’ to weigh them but it aroused researchers’ curiosity, ‘What on earth were they playing at?’” Franks says.
The researchers found that the amount of time the antlions remained stationary after being disturbed was unpredictable and was often quite lengthy. In researching other animals, they found that how long they wait to move again can depend on factors such as hunger and temperature, but it always varies.
This unpredictability is absolutely crucial for their survival, Franks says. For example, if a bird visits these antlion pits and the larvae “play dead”. the birds will fly around the antlions to see if they move. “Imagine if antlions always remained immobile for 5 minutes. In such case, the predator could look for alternate prey（猎物）and then return to its original one when the time is up,” he says. “If that happened, it would be a short life for the predictable death-feigner.” But because the time is unpredictable, the birds leave and go find something else to eat. The predators turn their attention from the unmoving prey that no longer catches their eye to something nearby that is a better alternative.

6 . Those days of sucking (吮吸) up the sides of your rapidly melting (融化) ice cream may soon be over. Researchers have discovered a natural protein that could be added to everyone’s favorite summertime snack to keep it solid for longer, according to a press release from the University of Edinburg in Scotland.
Most people know that, at its most basic, ice cream is made of milk and sugar. But it has other ingredients that give it a solid consistency (黏稠度) — a fat (often oil), air bubbles, and ice crystals. The protein that the researchers discovered, called BsIA, coats all three of them to slow down the rate at which the ice melts and the air escapes. In one study of the protein, published earlier this year, the researchers call BsIA a “raincoat” that can act as a film to keep everything inside it for just a little longer. That same quality prevents big pieces of ice crystals from forming, which can happen if you leave ice cream in the fridge for too long.
BsIA is found in bacteria called Bacillus subtilis that is common in soil, and is already present in some foods. So adding the protein to ice cream wouldn’t bring the same sorts of long-term health concerns as would artificial ingredients (人造添加剂). The researchers note that producers could also add BsIA to ice cream to reduce their fat and sugar content.
Though the researchers have published two papers about BsIA and have tested it in the lab, they are staying quiet on the most recent data they collected, as the Washington Post notes. Importantly, the researchers make no mention about how the new ingredient might affect ice cream’s taste or how much we might enjoy eating it. What’s the good of long-lasting ice cream if you don’t even like it? But it might not be too long before you can try it out for yourself; ice cream with BsIA might be available within three to five years.

7 . Norway aims to discover new resources beneath the sea, but its push into mining has raised environmental concerms.
Norway could license companies for deep-sea mining as early as 2023. That could place it among the first countries to harvest seabed metals. Copper, zinc and other metals are in high demand for electric vehicle batteries, wind turbines and solar energy centers. However, that could also place Norway on the front line of controversies over the environmental risks of mining the world’s unexplored seabeds.
Norway recently announced it was carrying out an environmental study needed to start mineral exploration and mining. Once that is completed, the govemment plans to have public comments on its environmental study and on a proposal to open areas for exploration and production by the end of 2022.
The demand for minerals is being driven by what are often called “clean” technologies. But the process of getting those minerals from the seabed could cause environmental problems.
Environmentalists including Britain’s David Attenborough have called for a temporary (暂时的) stop to deepseabed mining until more is known about how it affects sea life. The environmental group Greenpeace called for a total ban in a recent report. In another report, the High Level Panel for a Sustainable Ocean Economy, known as the Ocean Panel, also called for greater knowledge about the effects of deep-sea mining. The Ocean Panel is cochaired by Norway and has 14 member states that want to shape policy on the world’s oceans.
Norway is known as a major oil producer. But, the country of 5. 4 million people wants to find something to replace its top industry that is better for the environment and can grow in the future.
The move toward deep-sea mining follows three years of expeditions(探险). The Norwegian Petroleum Directorate, which carried out the work, said it found copper, zinc, cobalt, gold and silver. The expeditions also discovered large armounts of lithium and the rare earth metal scandium used in electronics and metal mixtures.

8 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie—all without other people hearing the sound. That is the possibility presented by “sound beaming,” a new technology from Noveto Systems, an Israeli company.
On Friday, the company presented a desktop device that sends sound directly to a listener without the need for headphones or a special receiver. Noveto Systems gave The Associated Press (AP) a chance to test its Sound Beamer 1.0 before its debut. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie. The sound seems so close it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D technology that finds and follows the ear position of the listener. It sends ultrasonic waves to create sound pockets by the user’s ears. Sound can be heard in stereo or 3-D. The 3-D method creates sound on all sides of the listener The demo version of the device included nature videos of birds on a lake, bees flying and a quiet waterway. By changing a setting, the sound can follow a listener around when they move their head. It also is possible to move out sound beam’s path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology. Its chief executive officer Christophe Ramstein said a smaller version of the device will be ready for release to consumers next year.

9 . If businesses are to get workers back into the office, finding ways to keep social distancing will be key. An Israeli company thinks it can help, using smart sensors installed on workplace ceilings.
PointGrab developed its technology before the Covid-19 to help workspace managers optimize 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 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 series 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 a company Cushman & amp; 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 centre in Belgium. While the social distancing innovation is new, PointGrab has installed more than 10, 000 sensors for workspace optimization, including in the offices of Coca-Cola, Facebook and Dell.
Workers might not like the idea of being monitored, but PointGrab says no images or identifying features are recorded. Instead, each employee is represented as an dot on a dashboard. “The sensor does not violate people’s privacy,” Shachar says. “This is extremely important in the workspace.”

10 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.
