1 . Being trapped in an elevator(电梯) can be one of the worst experiences of one’s life. Some people who have such experiences may be afraid to use elevator again. In fact, there are some useful tips to follow when people are in trouble with the elevator.
First, take deep breaths and keep calm. Too much fear will add to your panic(恐慌) and make you too nervous to think clearly. Tell yourself to be patient and believe that nothing is impossible.
Secondly, use the emergency(急救) call inside the elevator or your mobile phone to let people outside know your are stuck in the elevator. There is an emergency call on the wall of each elevator. You may use your mobile phone to give light and find it. The phone number can be found around it.
Thirdly, putting on messages on Wechat(微信) is also a good idea to allow more people to find you are in need of help. If help hasn’t come, knock the door hard to get attention from other people in the building.
Fourthly, move less and try to relax. Even if the workers have known your situation, it may take them a long time to repair the elevator and bring you back to safety. Instead of keeping moving all the time, you are advised to keep still and relax yourself as much as possible, or you will make yourself tired out. Make sure that you are fine when the door is open.

2 . 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.

3 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

4 . When whales die and sink to the ocean floor, their bodies -known as whale falls -provide rich nutrients for other creatures of the deep.
Chinese scientists found a whale fall in the South China Sea during a recent scientific research voyage. It was the first time that Chinese researchers had run across this rare type of ecosystem. It was an important finding, showing China's progress in deep-sea exploration technology, Xie said, a professor at Sun Yat-sen University.
During the 22-day deep-sea exploration from March 10 to April 2. 60 scientists conducted 22 dives and successfully completed a number of scientific tasks. The research aimed to gather information about the key processes of typical seamount ecosystems in the Western Pacific: Ocean. The whale fall was found in a seamount 1,600 meters deep in the central South China Sea. Though the whale fall was only about 3 meters long, it was of great importance in understanding the sea ecosystems, Xie said.
There were dozens of white armored shrimp, red shrimp and several eels found near the whale fall. The eels were eating the tail muscles of the whale fall. This shows that the whale died not long ago and that the whale fall was still in the first stage of decomposition and thus had rare value for long-term observation, Xie said.
Like cold springs, whale falls are homes for creatures of the deep. In the northern Pacific Ocean, they have supported the survival of at least 12,490 kinds of organisms—classed in 43 species—and promote prosperity far beneath the surface, according to data from the university.
