With global warming and melting ice, it isn’t easy being a polar bear anymore. Some studies have predicted that polar bears could die out by the end of the century. The good news is not all researchers think the bears are absolutely disappearing. Scientists at the American Museum of Natural History(AMNH) have published a new paper indicating that things might not be as bad for polar bears as some scientists expect.

To understand the reason for the researchers’ cautious optimism, we must first understand the factors that are threatening the polar bear’s existence. Polar bears consume a diet of mainly young seals. In order to hunt these seals, polar bears need to rest at the top of sea ice---the same ice that is increasingly melting for most of the year thanks to climate change. In another 50 years, experts expect that the Arctic will be too warm for sea ice to form for half of the year, leaving polar bears without a reliable food source and in serious danger of starvation.

As it turns out, alternative food sources for the polar bears aren’t completely out of the question. For as long as biologists have tailed after the animals, they’ve seen polar bears eating animals found on land like caribou(驯鹿) and snow geese---as well as the snow geese’s eggs.

Can polar bears actually survive off these alternative food sources for long periods of time? To figure this out, researchers calculated the nutrients that a caribou and snow geese diet would provide. They found that even adult male polar bears would be able to obtain more calories than they would burn in hunting these meals. Moreover, the food would provide the food necessary to avoid starvation during the summer months.

Unfortunately, not all polar bears have tended to seek food on land. That said, the researchers expect that necessity would push more polar bears to hunt on land to avoid starvation. They also expect that the bears could learn from their fellow bears how to hunt on land until the practice becomes second nature.

A tender woman,or an independent one,which one would you prefer? A recent research shows that most people would choose the latter.

This type of woman is called a nühanzi (“tough woman”).Experts believe these characteristics have social and psychological roots among young females in China.Su Hao’s friends all call her a tough woman,because she can finish tough tasks usually carried out by men.For example,she carries 10litre water to her dormitory on the 5th floor.“I depend on no one but myself,” she says.

According to a recent survey by China Youth Daily,tough women have become rather common in society.Of the 21,265 respondents,78.5 percent said they are familiar with a tough woman.About 50 percent said they like women with tough characteristics,while less than 29 percent expressed the opposite view.

Why are tough women gaining popularity? Shen Meng,a psychological consultant,believes the fierce competition in society is contributing to this trend.“Women are often in a disadvantaged position compared to men,” Shen says.“In order to survive,they have to be independent,strong and tough.” Liu Xiaolin,professor of psychology at Wuhan Mental Health Center,believes tough women are brought up this way.They are often on close relationship with their fathers,who teach their daughters to be brave and decisive,” he says.As a result,these women are more likely to be psychologically healthy and more tolerant to stress,according to Liu.

Though Liu believes that this is a good trend,Hu Shenzhi,a psychologist at the Guangdong Sunflower Counseling Center,says the popularity of tough woman indicates an unclear line between gender identities,which can lead to relationship problems.“Some women with characteristics that differ from the traditional female image may have a difficult time finding Mr Right,” he says.“Even if they get married,their manly characteristics might cause family conflicts.
