1 . The world’s hottest rainforest is located not in the Amazon or anywhere else you might expect, but inside Biosphere (生物圈) 2, the experimental scientific research facility in the desert outside Tucson, Arizona. A recent study of tropical trees planted there in the early 1990s reported a surprising result: They have withstood temperatures higher than any likely to be experienced by tropical forests this century.

The study adds to a growing number of findings that are giving forest scientists something that’s been in short supply lately : hope. Plants may have unexpected resources that could help them survive — and perhaps even prosper — in a hotter, more carbon-rich future. And while tropical forests still face both human and natural threats, some researchers believe terrible reports of their approaching decline due to climate change may have been overstated.

“Biology is clever, ”says Scott Saleska, an ecologist at the University of Arizona in Tucson and co-leader of the Biosphere 2 study. “It’s a lot smarter than our models yet represent.”

The last few years have seen a flood of alarming reports about forests and climate change’s effects on them. Scientists have announced that the Amazon forest is no longer a reliable carbon sink; the Amazon rainforest may be nearing a tipping point; tropical forests globally are already close to the hottest temperatures they can tolerate and climate change is killing off old trees.

One thing is certainly true: Our fossil fuel emissions are creating a climate that humans have never seen and trees haven’t experienced in a very long time.“We’re pushing tropical forests into temperatures they’ve never seen since the Cretaceous — since there were dinosaurs,” says Abigail Swann, an ecologist and climate scientist at the University of Washington in Seattle.

3 . When you’re on a fishing boat, you may see flocks of birds following in your track, hoping to catch a snack. Now scientists say they can use those birds’ behavior to track illegal fishing boats.

Here’s how it works: Researchers attached data recorders to the backs of 169 albatrosses (信天翁) in the Southern and Indian oceans. The devices weighed only an ounce and a half, but they included a GPS and were able to detect the presence and intensity of radar signals coming from boats. That information was then transmitted by satellite, so the researchers could track the location of the birds-and thus the radar-emitting boats-in real time.

The scientists then cross-checked that data against the known locations of boats, gathered from a system that boats use to declare themselves, called the Automatic Identification System (AIS). And differences appeared frequently.

More than a third of the times the birds’ recorders detected radar signals, and therefore a boat, no such boat appeared in the official log (航海记录)—meaning that the vehicles had likely switched off their Automatic Identification Systems—something the researchers say probably happens in illegal fishing operations.

The work suggests birds could be an effective boat-monitoring tool—as long as illegal fishing operations don’t target the birds. Fortunately, such a task would be difficult.

“Around fishing vessels, you can get hundreds of birds at any one time that are all flying around. So it’s not really possible to target a specific bird. And the birds with recorders on are not marked in any way. So it’s difficult for fishermen to pick out a specific bird," said study author Samantha Patrick, a marine biologist at the University of Liverpool.

Patrick’s bigger concern is that albatrosses often get hooked on fishing lines. And though regulations have been established to protect against that happening—with success—illegal boats don’t necessarily obey. So scientists might be underestimating the risk posed to albatross populations. But this system could mean that those illegal boats may have a tougher time flying under the radar.

4 . The vaccine (疫苗) news continues to seem very encouraging. Britain started its mass vaccination effort and the U.S. isn’t far behind.

But there is still one dark cloud hanging over the vaccines that many people don’t yet understand.

The vaccines will be much less effective at preventing death and illness in 2021 if they are introduced into a population where the coronavirus is still severe—as is now the case in the U.S.

A vaccine is like a fire hose (消防龙头). A vaccine that’s 95 percent effective, as Moderna’s and Pfizer’s versions appear to be, is a powerful fire hose. But the size of a fire is still a bigger determinant of how much destruction occurs.

At the current level of infection in the U.S. (about 200,000 confirmed new infections per day), a vaccine that is 95 percent effective—distributed at the expected pace—would still leave a terrible toll (伤亡人数) in the six months after it was introduced. Almost 10 million or so Americans would catch the virus, and more than 160,000 would die.

This is far worse than the toll in a different situation where the vaccine was only 50 percent effective but the U.S. had reduced the infection rate to its level in early September (about 35,000 new daily cases). In that case, the death toll in the next six months would be kept to about 60,000.

It’s worth pausing for a moment on this comparison. If the U.S. had maintained its infection rate from September and Moderna and Pfizer had announced this fall that their vaccines were only 50 percent effective, a lot of people would have panicked.

But the reality we have is actually worse.

How could this be? No vaccine can get rid of a pandemic immediately, just as .no fire hose can put out a forest fire. While the vaccine is being distributed, the virus continues to do damage.

There is one positive way to look at this: Measures that reduce the virus’s spread—like mask-wearing, social distancing and rapid-result testing—can still have great consequences. They can save more than 100,000 lives in coming months.

6 . Hazel Mayfield usually cooks the Thanksgiving meal for her extended family in Houston, Texas. She usually welcomes friends and neighbors eager to sample her fried turkey, green bean casserole , candied yams, homemade cornbread dressing, and dirty rice -just a few of her signature dishes. Known as Suga Mama, because her grandchildren think she’s so sweet, the 91 -year-old typically likes to do her own shopping for the ingredients to make her special dishes.

“My mother is the head cook of the family,” said Paulette Mouton, Mayfield’s daughter.“Because of her reputation, you know, there’re people in and out all day, everybody’s family comes through. They want to get some of Suga Mama’s cooking. We’re from Louisiana and we cook all that.”（ One in six Americans could go hungry in 2020 as pandemic persists. ）

But Mayfield hasn’t been to the grocery store since March. And there is little about Thanksgiving 2020 that’s usual. Hundreds of thousands of American families have re-imagined the holiday with virtual celebrations, canceled or delayed travel plans , or for small gatherings with people in their households in response to COVID-19, the deadly virus that has killed more than 250,000 in the U.S. and spoiled life around the world.

This year, Mayfield’s family members are lamenting（ 悲叹） the absence of a big gathering. They’ve   explained to their young children and grandchildren why this year’s Thanksgiving is different. Mayfield’ s youngest daughter, Michelle Sanders, says it’s tough helping her grandchildren understand why they can’ t see some of their other family members.

“It’s really hard, trying to explain to them,”Sanders said. “When you’ re talking to them and they want to come over, you have to tell them no. They really don’t know how to be careful.”

Sanders added,“And, they don’ t understand that, being three, four, and six, you know they don’t really understand that.So, it’s ... it’s really, really hard, and heartbreaking. ”

7 . The Tibet autonomous region has placed nearly half its land area under the strictest ecological supervision (监督).It was announced at an annual meeting of the regional People's Congress, which kicked off on Wednesday.

The ecological protection area, which covers more than 539,000 square kilometers, makes up 45 percent of the region's area, and 22 ecological reserves have been built and are operational.

According to the government work report, the rate of days with good air quality in Tibet's cities has reached 99.4 percent, and all the region's drinking water sources have met applicable standards.

The report also said that the number of Tibetan antelope (羚)in the region has risen to more than 200,000, wildlife species to 1,072 and black-necked cranes to more than 8,000. Five rare new species have been discovered in recent years. The region has spent 12.2 billion yuan ($1.9 billion) on ecological protection projects in recent years. Five cities and three counties have been named as national-level ecologically civilized model cities and counties, and more rural residents have benefited financially by undertaking part-time ecological protection work.

More advanced monitoring facilities have been in place in the reserve, with more ecological protection inspectors employed to undertake protection work. The professional ecological inspectors are provided with basic tools such as motorcycles, telescopes and paging receivers, and they provide feedback regularly. Professional inspectors also receive one week of training every year from professors at Tibet University.

Kunsang Darje, a railway maintenance worker in Nagchu, said that apart from maintaining the railway and highway, he also collects trash along the section with his colleagues. “The place I work is in a no-man's land, and I think it's very important to protect the animals there without affecting them with human activities, and we are also bound to take responsibility there," he said.

9 . One of the fundamental things we really love in cities is order. Order means balance, symmetry （对称）and repetition: the same thing happening again and again, and the left side matching the right side.

Order is one of the reasons why so many people love Paris. But most cities are a complete mess. When it's a mess, it seems like no one is in charge. And that's worrying. It's horrible when everything is jumbled up: a pitched roof next to a flat roof; 3 simple bare box next to a messy car park; high-rise towers that look as if they've been placed at random, like teeth in a yawning mouth.

We generally have a desire to straighten things out. And when we can't, it's frustrating. The same urge is there when we look at cities. Often, it's not skyscrapers that we mind in the city. It's skyscrapers that have been planted there without planning, like they are increasingly appearing in London, while New York or Chicago shows the ordered way that we love.

However, you have to keep something else in mind. Unreasonable order can be just as much of a problem. Too much regularity can be soul-destroying. Too much order feels rigid and alien. It can be indifferent, cold, severe, unkind, or even cruel. So the ideal we're seeking is variety and order.

This is the idea in a square in Tele in the Czech Republic, where every house is the same width and height. But within that ordered partem, every house has been allowed freedom at the level of form and color. We're perfectly in the middle between chaos and boringness here. And that's what humans adore.

So as a general rule: too much mess, and it's off-putting; but too much simple order, and it’s boring.

10 . Bricks are one of the oldest known building materials, dating back thousands of years. But researchers at Washington University in St. Louis have found a new use for bricks: as energy storage units. A team of engineers and chemists have found a way to transform an ordinary house brick into a “battery”—allowing it to conduct and store electricity. The bricks are powerful enough to light up an LED bulb, and cost only about 3 dollars to make.

“I love the idea of adding value to things that are inexpensive, things that are affordable, things that we kind of take for granted,” says Julio D'Arcy, who is an assistant professor of chemistry at Washington University and one of the researchers on this project.

The brick-battery relies on the reddish pigment known as iron oxide, or rust, which gives red bricks their color. The scientists pumped the bricks with several gases that react with iron oxide to produce a network of plastic fibers. These small fibers coat the empty spaces inside the bricks — and conduct electricity.

What the researchers are trying to do is to make specialized plastics that are only used on the nanoscale where they use very little of the plastic and they can actually fix that plastic firmly inside construction materials.

In the future, D'Arcy says, a brick wall could potentially serve a dual purpose: providing structural support and storing electricity generated from renewable energy sources, such as solar panels.

The technology is still at least a few years away from being ready for the commercial market. And right now, the energy storage capacity of the bricks is still pretty low—about 1 percent of a lithium ion battery. But the team is now testing ways to improve brick performance. hoping to make a breakthrough and practical application to better the seemingly ordinary construction materials as soon as possible.
