Two recent studies have found that punishment is not the best way to influence behavior.

    One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.

    They had about two hundred college students play a version of the game known as the Prisoner's Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.

    The other study involved children. It was presented last month in California at a conference on violence and abuse（虐待）. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.

    The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.

    For years, people have wondered whether there's life on other planets. Scientists may now be closer than ever to answering that question.

    Using powerful telescopes, a team of astronomers in South America discovered a new planet, called Proxima b. It circles a star named Proxima Centauri, in the same way Earth circles the sun. Proxima Centauri is the closest star to our solar system.

    Scientists believe the new planet has a rocky surface and is similar in size to Earth. More important, they've determined that the distance between Proxima b and its “sun” gives the planet a similar temperature to Earth's.This means it could have liquid water. The presence of water on a planet makes it possible for life to exist there. Scientists refer to planets like Proxima b as “Goldilocks planets” because they are not too hot or too cold, but just right to possibly support life.

    Astronomers have found other Goldilocks planets in the past, but none are as close to Earth as Proxima b. Still, the new planet is 4.2 light years from Earth—that is about 25 trillion miles away.

    Despite the long distance, astronomers hope to get a much better look at our new-found neighbor one day. But they'll need to wait until more advanced telescopes are developed. They may also send a robotic spacecraft to investigate the planet.

    We all know that listening to music can soothe emotional pain, but Taylor Swift, Jay-Z and Alicia Keys can also ease physical pain, according to a study of children and teenagers who had major surgery.

    The research was carried out because of a very personal experience. Sunitha Suresh was a college student when her grandmother had major surgery and was put in intensive care (重症监护). This meant her family couldn't always be with her. They decided to put her favorite music on an iPod so she could listen around the clock.

    It was very calming, Suresh says. “She knew that someone who loved her had left that music for her and she was in a familiar place.”

    Suresh could see that the music relaxed her grandmother and made her feel less anxious, but she wondered if she also felt less pain. That would make sense, because anxiety can make people more sensitive to pain. At the time Suresh was majoring in biomedical engineering with a minor (兼修) in music cognition (认知) at Northwestern University where her father, Santhanam Suresh, is a professor of pediatrics (儿科).

    So the father and daughter decided to do a study. And since Dr Suresh works with children, they decided to look at how music chosen by the children themselves might affect their tolerance for pain.

    It was a small study, involving 60 patients between 9 and 14 years old. All the patients were undergoing big operations that required them to stay in the hospital for at least a couple of days. Right after surgery, patients received narcotics (麻醉药) to control pain. The next day they were divided into three groups. One group heard 30 minutes of music of their choice, one heard 30 minutes of stories of their choice and one listened to 30 minutes of silence via noise canceling headphones.

    After a 30-minute session, the children who listened to music or books reduced their pain burden by 1 point on a 10-point scale. Sunitha Suresh says it's equal to taking an over-the-counter pain medication like Advil or Tylenol.

    The findings suggest that doctors may be able to use less pain medication for their pediatric patients. And that's a good thing, says Santhanam Suresh, as children are smaller and are more likely to suffer side effects. So the less pain medication, he says, the better.

    A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.

    Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission.

    "The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."

    Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."

    There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

    Climate change, pollution, overuse of water and development are killing some of the world's most famous rivers including China's Yangtze. India's Ganges and Africa's Nile. WWF said on Tuesday. At the global launch of its report "World's Top 10 Rivers at Risk", the group said many rivers could dry out. affecting hundreds of millions of people and killing unique aquatic (水生的) life.

    "If these rivers die, millions will lose their livelihoods, biodiversity (生物多样性) will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security, "said. Rayi Singh, secretary—general of WWF—India. The report, launched ahead of "World Water Day" today, also cited the Rio Grande in. the United States, the Mekong and Indus in Asia, Europe's Danube, La Plata in South America and Australia's Murray—Darling as in need of greater protection.

    Rivers are the world's main source of fresh water and WWF says about half of the available supply is already being used up. Dams have destroyed habitats and cut rivers off from their flood plains, while climate change could affect the seasonal water flows that feed them, the report said. Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found. The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes (流入) of sediment (积淀) from land conversion.

    Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa's arid Nile basin. Tributaries (支流) flowing into the Ganges are drying up because of irrigation, WWF said.
