Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.

    My friend BJ Gallagher told me a great story recently, about her own experience with resentment (愤恨). She once worked as the training manager for a large newspaper, where she found the corporate culture extremely frustrating. The company was a hundred years old and their past success ha d blinded them to the need for change. Finally, after butting heads with several senior executives (主管) many times, she left the company. But she found that she hadn't left her resentment, frustration, and anger behind when she resigned.

    “I finally decided to write about my experiences and my feelings at the newspaper. I wanted to be rid of that company and those people, once and for all. So I wrote and I wrote. It wasn't just a story that poured out; it was a whole book! We called it A peacock in the Land of Penguins. I was the peacock and those newspaper executives were the penguins.”

    “It took me several more years to finally get over my negative emotions. Through a lot of soul-searching and reflection, I finally was able to let go of my resentment. I came to see that there was nothing personal in the way they treated me, and they were good people doing what they thought best for the company. I was the one who had made it personal. I thought they were making my life miserable on purpose.”

    “Finally, the time came when I decided to make amends (弥补) for the sharp, angry things I had said about the company. I invited my former boss to dinner and made my apology. It was a great healing process for me. I finally felt free of the resentment that had been eating me up.”

    “What was the final outcome?” I asked her.

    “Gratitude,” she replied. “Not only wasn't I resentful any more, I was grateful to the company. If I hadn't had those painful experiences, I would never have written a book. And the book became hugely successful – now published in 21 languages; it transformed my business.”

    A man had a dream in which he was told where he could find fantastic wealth in a remote place. When he awoke, he immediately set off to find it. After a long journey full of danger and hardship, he arrived at the place in his dream. A local man who had heard about the dreamer's purpose laughed loud and long, saying that he had dreamed three times about a house where great treasure was buried under a fountain. It made the dreamer realize that the place the local was describing was his very own yard. He returned home and found the treasure.

    Like the man in this tale, the Chinese movie industry has been on a long journey to find its place in the world. In 1994, “The Fugitive” became the first major Hollywood film to be shown in the country in decades. Audiences were attracted by the movie's fast pace and sound effects, and it proved to be a great success. Since then, the Chinese film industry has balanced a complex (复杂的) relationship with Hollywood.

    Although there has been a sharp slowdown in China's box-office numbers—movie-ticket revenue rose just 3.7 percent in 2017 after growing by an average of 35 percent per year from 2011 to 2016~the country still has a huge movie market, with theaters continuing to expand into more rural areas and audiences proving that they have a strong desire for Hollywood action films. So much so that recently, Hollywood has even started to make movies with China in mind, casting Chinese movie stars with great box-office power and changing the plots of films to win over Chinese moviegoers.

    Many in China's film industry, from young scriptwriters (编剧) to senior critics, know Hollywood's dramatic structure all too well and support its styles. And many American offerings introduced in the Chinese market, regardless of quality, continue to do well among Chinese audiences, especially with young people, whose tastes and viewing habits have been shaped by Hollywood movies and TV shows. Like audiences in other developing countries, those in China tend to have a worldview filtered (过滤) by and focused on the United States, even though the United States doesn't mean the whole world and Hollywood isn't the world's only movie industry.

    Like an ocean that refuses no rivers, China's movie industry will continue to influence and allow itself to be influenced by its international counterparts (对应的人或物). China needs the United States, and the United States needs China. But at the moment, a large difference exists in that very few Chinese movies are able to enter the American market and attract a significant audience. Chinese audiences provide Hollywood with huge profits, but what does China's film industry gain in return?

    A mother goat is able to pick out her own baby from its voice alone by the time the kid is just five days old.

    Researchers from University of London played kids' bleats to female goats and studied their responses. They were surprised to find that the animals were able to pick out their own kids' voices.

    “A mother and the kid rely a lot on smell to recognize one another and, in the wild, during the first week of their lives, the animals hide in grass and don't call much. It's a strategy they use to avoid enemies,” Dr Elodie Briefer, who led the research, explained to BBC News. “The mother call to the kids when she want them to come and feed, so we expected that kids would recognize the mothers' voices.” In fact, this was the case for deer, which also use this hiding strategy, although they do not belong to the same family of species as goats.

    She and her team recorded and played back young kids' calls to the female goats and recorded their responses. She explained, “Even when the calls came from kids that are five to six days old, we could see the mothers responding more to the voices of their own babies.” Hearing the voice of their own kids, the females would look towards the speaker that the sound was coming from, moving around and calling in response.

    The scientists say that understanding how goats behave and communicate is very important. “This helps us understand just how smart these animals are,” said Dr. Briefer. “Farmers might be able to change their way to raise goats considering this natural behaviour.”

    Scientists are trying to save Puerto Rico's endangered Amazon parrots after Hurricane Maria destroyed the birds' habitats and food sources(来源).

    El Yunque is a large national forest on the eastern part of Puerto Rico. Just two of the 56 wild parrots that once lived there survived Maria, the Category-4 storm that struck Puerto Rico in September 2017. Scientists report other forests have seen great drops in parrot populations as well.

    In the 1800s, there were more than a million of the bright green parrots living in the wild in Puerto Rico. By the 1970s, the number was down to just 13 birds after years of forest clearing.

    A special program was started in 1972 to help increase the parrot population, which led to the creation of three breeding(繁殖) centers. Just weeks before Hurricane Maria hit, scientists counted 56 wild parrots at El Yunque. That was the highest number in the program's history. Scientists say that even though several parrots have been born in captivity(笼养) and in the wild since Maria, the species is still in danger.

The Puerto Rican Amazon is the island's only remaining native parrot. More than 460 of the birds are kept inside the breeding centers at El Yunque and the Rio Abajo forest. Scientists have not released(释放) any of the birds since Hurricane Maria. A third breeding center, in a forest in the western area of Maricao, has not been in operation since the storm.

    Scientists are considering whether to catch some of the remaining wild parrots and put them in the same cage as the birds that are set to be released. This way, the captive birds can learn from the wild birds how to survive in the forests. Another consideration is to release some captive parrots in Maricao, which was not as heavily damaged by Maria.
