1 . Regardless of how famous they are, and despite the star treatment they receive, many celebrities make it a point to give back to charities. Some have even set up their own private foundations. Their widely publicised visits to troubled areas of the world help to raise awareness of issues such as famine and poverty. According to Jane Cooper of Unicef UK, celebrities have a unique ability to reach huge numbers of people, many of whom might not otherwise be engaged in charitable causes. She pointed out that famous faces had played a significant role in raising funds in recent years, and their energies had produced tangible results, such as enabling millions of children in poorer countries to attend school.
But in spite of these successes there is evidence to suggest that celebrity endorsement (代言) may be overrated. In a survey of members of the public to find out if celebrity involvement would encourage people to donate, researchers found that the impact was not as great as previously thought. When shown a list of well-known organisations and famous people who represent them, over half of respondents were unable to match the celebrity with the cause. What’s more, three quarters claimed that they didn’t respond to celebrity endorsement in any way. The survey also showed that a few names did stand out as being associated with particular charities. But the presence of a celebrity in a campaign, was not a significant factor when it came to a decision to donate time or money. Instead, the majority of people contribute because of personal connections in their lives and families which make a charity important to them.
In another study aimed at young people, most participants cited a compelling (无法抗拒的) mission as their main motivation to give. The second most important incentive was if a friend or peer recommended supporting a particular cause. Only two percent of respondents said they were motivated by celebrity endorsement. This seems to contradict the general assumption that teenagers are particularly influenced by famous people. One possible explanation is that there is a general fatigue (疲倦) with celebrity culture. There is also a suspicion that the stars are the one who benefit most when they offer to do charity work. Some critics have accused that celebrities might actually take attention away from issues by attracting more attention than the causes they represent.
So taking all these issues into account, is it time for charities to rethink their campaign strategies and look for alternative ways to reach new audiences? Whichever point of view you favour, there seems to be opportunities for more research into how charity campaigns might develop relationships with celebrities to maximise their potential. This in turn will open up more engagement, and better targeted campaigns-which can only benefit those who really matter — the people and animals that are in need of assistance.

2 . Young children who have experienced compassionate (有同情心的) love and empathy (认同感) from their mothers may be more willing to turn thoughts into action by being generous to others, a University of California, Davis’ study suggests.
In lab studies, children tested at ages 4 and 6 showed more willingness to give up the tokens (代金券) they had earned to fictional children in need when two conditions were present—if they showed bodily changes when given the opportunity to share and had experienced positive parenting that modeled such kindness. The study initially included 74 preschool-age children and their mothers. They were invited back two years later, resulting in 54 mother-child pairs whose behaviors and reactions were analyzed when the children were 6.
“At both ages, children with better physiological regulation and with mothers who expressed stronger compassionate love were likely to donate more of their earnings,” said Paul Hastings, UC Davis professor of psychology. “Compassionate mothers likely develop emotionally close relationships with their children while also providing an early example of satisfying the needs of others,” researchers said in the study, published in November in Frontiers in Psychology” Emotion Science.
In each lab exercise, after attaching a monitor to record children’s heart-rate activity, the examiner told the children they would be earning tokens for a variety of activities, and that the tokens could be turned in for a prize. The tokens were put into a box, and each child eventually earned 20 prize tokens. Then before the session ended, children were told they could donate all or part of their tokens to other children.
Taken together, the findings showed that children’s generosity is supported by the combination of their socialization experiences—their mothers’ compassionate love—and their physiological regulation, and that these work like “internal and external supports for the ability to act prosocially that build on each other”.
In addition to observing the children’s propensity (习性) to donate their game earnings, Hastings suggested that “being in a calmer state after sharing could reinforce (加强) the generous behavior that produced that good feeling.”

3 . Some scientists have detected a chemical on Venus (金星) that isn’t expected to be there, which leads them to wonder what is producing the chemical.
Venus may look beautiful in the night sky, but it’s a harsh planet. Its clouds are made of acid. And its atmosphere is so thick that if you could stand on the planet’s surface, you would feel like you were 3,000 feet under the sea. It is the hottest planet in the solar system, with an average temperature of 464℃. Though people have often wondered if Venus used to have life, most people don’t believe life exists there. Now, as a result of work by a group of scientists led by Dr. Jane Greaves from Cardiff University, there may be reason to question that.
The scientists found a molecule called phosphine (磷化氢) in Venus’ atmosphere. On Earth, some bacteria produce small amounts of phosphine in oxygen-free environments. Phosphine molecules aren’t very stable, so they tend to break apart or burn up easily.
Many scientists believe phosphine might be a sign of life on other planets. So the scientists were puzzled when they found signs of phosphine high in the atmosphere of Venus. They double-checked their result and it was the same — high in the clouds there appeared to be too much phosphine.
That led the scientists to think about what could make the phosphine. They studied many ideas, from sunlight, lightning strikes to volcanoes. But none of these could produce the amount of phosphine they detected. One possible explanation for the phosphine is simple — life. For example, some sort of bacteria can somehow survive in the acid clouds of Venus.
The discovery of phosphine on Venus has caused a lot of excitement. The scientists behind the study are eager to do more research. Now, many other people are also looking to focus on the planet and perhaps even create missions to explore Venus’ atmosphere.

4 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.
The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.
The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.
Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.
“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.
“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

5 . Coca-Cola is to test a paper bottle as part of a longer-term goal to get rid of plastic from its packaging entirely. The prototype (样本) is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner (衬垫). But the goal is to create a 100% recyclable, plastic free botte capable of preventing gas escaping from carbonated (碳酸) drinks. The barrier must also ensure no fibers get into the liquid.
That may have a risk of changing the taste of the drink — or potentially can't meet the requirements of health and safety checks. But industry giants (巨头) are backing the plan. Coca-Cola, for example, has set a goal of producing zero waste by 2030. Coca-Cola was ranked the world's number one plastic polluter by charity group Break Free From Plastic last year, closely followed by other drink-producers Pepsi and Nestle.
The Paper Bottle Company, or Paboco, is the Danish firm behind the development of the paper-based container. Part of the challenge has been to create a structure capable of standing the forces exerted by carbonated drinks — such as cola and beer — which are bottled under pressure. On top of that, the paper needs to be mouldable to create distinct bottle shapes and sizes for different brands and take ink for printing their labels.
After more than seven years of lab work, the firm is now ready to host a trial in Hungary this summer of Coca-Cola's fruit drink Adez. Initially, this will involve 2,000 bottles distributed via a local retail chain.
But it is also working with others. Absolut, the vodka maker, is due to test 2,000 paper bottles of its own in the UK and Sweden of its pre-mixed, carbonated raspberry drink. And beer company Carlsberg is also building prototypes of a paper beer bottle.
Michael Michelsen, the firm's commercial manager, says the bottles are formed out of a single piece of paper-fiber-based material to give them strength.

6 . In an incredible display of compassion and kindness, a man from Turkey was spotted trying to warm a pigeon in the most creative way.
Sabahattin Yılmaz was at home one chilly day. After a rain shower had passed, he noticed something landed on the sill (窗台) outside his window—a cold and wet pigeon. The animal was trembling and soaked; it clearly didn’t have the chance to seek shelter before the rain began. Feeling for the poor pigeon, Yılmaz thought of a way to dry him off.
Rather than pick him up and take him inside to warm up, Yılmaz plugged in a hairdryer and used it to dry off the bird. Little did he know that his neighbor captured the whole moment on video. In the video, Yılmaz can be seen leaning out of his window. He was stretching his arm as far as he can so the hot air can reach the pigeon. The bird willingly let the man warm him up, crouching (蹲伏) to let his outer feathers dry.
Yılmaz told the media that he spent about fifteen minutes drying off the bird. He said he had just opened his window when he saw the pigeon around the corner of the sill. He described it as wet and “about to freeze” from the cold and rainy weather.
After fifteen minutes, Yılmaz gave the pigeon birdseed, which he ate happily. However, the bird remained wet still. “I saw that it was still there so I warmed it up again, after the pigeon recovered again, and after eating a good amount of seed, it flew away,” Yılmaz recalled.
He also didn’t know that he was being recorded at the time and that the video was shared online. He simply did it out of the kindness of his heart. “The pigeon is a living creature and deserved to continue living, that is why I did it,” he said.

7 . Sophia Gholz is an award-winning children's book author, music lover. and magic seeker. Sophia enjoys writing fiction with humor and heart. When writing nonfiction, she pulls on her love of science and her family background in ecology.
Her book, The Boy Who Grew a Forest, shares the true story of Jadav Payeng, a man in India who single- bandedly planted an entire forest over the course of his lifetime. When he was younger, Jadav Payeng was shocked by the destruction of his island home. So he took matters into his own bands and began planting one seed at a time. Jadav's forest is now over 1300 acres and provides a home to many animals, some endangered. Jadav is still planting today and his hard work has now been celebrated around the world.
To write this story, Sophia got to know more about Jadav Payeng and his forest through a documentary film called Forest Man. Influenced by her father, a forest ecologist and a scientist, she grew up learning about the importance of trees and the natural world. When she heard about a man on a m1ssion to reforest an entire island on his own, she was drawn to this story.
As for research, most of her research was done online. She read every news article that she could find about Jadav and listened to every interview. Then she reached out to several people who had met or interviewed Jadav as well, including the producer of his short documentary film.
She hopes that The Boy Who Grew a Forest lights a spark in everyone who reads it to go out and care for our beautiful planet. She'd love young readers to be inspired to plant or to learn more about animal habitats, biodiversity and science in general.

8 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

9 . When you hear the beginning of your favorite song from the radio, suddenly your neck is covered in goose bumps.
It's such a thing that a group of scientists call “skin excitement”—a feeling of cold caused not by a drop in temperature or sudden scare, but by the sense of beauty. “Skin excitement” can come from a song, a painting, a moving movie scene, or even a beloved memory-pretty much anything that causes the giving out of pleasure-soaked dopamine in your brain. But it does not come for all of us.
Your favorite music uncovers a lot about your personality，and so does how you respond to that music. Studies suppose that as few as 55 percent of people experience “skin excitement” when listening to music. And if you count yourself among this group, the goose bumps on your skin aren't the only giveaway—scientists can read it in your brain, too. In a new study published in the journal Social Cognitive and Affective Neuroscience, Harvard researchers performed brain scans on 10 students who said they reliably got cold when listening to music, and 10 students who didn't. They found that the cold-prone brains may really be excited by stronger emotions.
Cold-prone brains are generally more likely to show stronger emotional intelligence than no-cold brains. Cold-prone minds tend to have unusual active imagination, reflect more deeply on their emotions, and appreciate nature and the beauty of music and art to a stronger degree than no-cold brains.
So, what type of music causes the chills? It seems that the type is not so important; participants in the new study reported getting cold from songs of every kind. And any song connected with a strong emotional memory of the listener can produce the most reliable results. For me, that's the song Sailing to Philadelphia by Mark Knopfler, which I listened to as a kid in the car with my dad, on the way to the summer camp.

10 . A shocking news report has revealed that more than one in five species of maple trees faces extinction, warning that 75% of the threatened species are “geographically restricted” in their native regions.
The trees are experiencing a vast decline in habitat, due to urban development, wood harvesting and agricultural expansion. Time is running out for the world's biodiversity. Every recent survey of plants and animals in the wild points to this. This is happening nearly everywhere rarer maples exist. And because of climate change, the narrow habitats that support species at the edges of dry places and at the tops of mountains are quickly disappearing.
The trees can be found in subtropical and tropical regions, as far south as Indonesia. The only species found in the UK, the field maple is not under threat. Not only are the trees a popular attractive feature in parks and public spaces, but they are a key part of the natural ecosystem in woodlands, as well as being an important wood crop in several countries. Although the sugar maple in North America, which produces maple juice, is not endangered, two of the closest relatives to the species are endangered.
The report notes that conserving at-risk species in their natural habitat is the best conservation tactic. But collections in botanical gardens and seed banks-called "ex situ collections" can act as insurance policies against extinction. There are currently 14 species of maple, including four that are critically endangered, which are absent from these types of collections.
One species in Mexico, the Acer binzayedii, is in “desperate need of conservation"”despite only being discovered in 2017. “It is at risk from climate change in its cloud forest habitat and threatened by logging and forest fires while it is also absent from 'ex situ collections',” the report adds. The report recommends developing conservation plans, monitoring species currently not at risk to ensure populations are maintained, and adding those missing maple species to seed banks.
