In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.

About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.

That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.

“We were operating on the presumption that nothing’s there.” said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”

“We were just gaga (狂热的) over it,” he said when talking about the 7.5cm long, orange creature starring in their two-minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.

The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?

Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.

But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm-wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small area,” she said.

“Yet scientists were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t,” Kim said.

“So how do they survive? That’s the key question.” Kim said.

“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.

Being a mother is apparently not like it was in the good old days.

　　Today’s parents yearn for the golden age that their own mothers enjoyed in the 1970s and 1980s, researchers found. Mothers have less time to themselves and feel under greater pressure to handle work and family life than the previous generation. As a result, 88 per cent said they felt guilty about the lack of time they spent with their children.

The survey of 1,000 mothers also found that more than a third said they had less time to themselves than their mothers did – just three hours a week or 26 minutes a day. And 64 per cent said this was because they felt they ‘had’ to go out to work, while nearly a third (29 per cent) said they were under constant pressure to be the ‘perfect mother’, the report found.

Other findings showed social networking and parenting websites, as well as technology such as Skype, were important in providing help and support among female communities. Kate Fox, a member of the Social Issues Research Centre, which conducted the survey for Procter & Gamble, said: ‘With increasing pressure on mothers to work a “double shift” — to be the perfect mother as well as a wage-earner — support networks are more important than ever.

It comes as a separate report examining childcare in the leading industrialised nations found that working mothers in Britain spend just 81 minutes a day caring for their children as a ‘primary activity’. Mothers who stay at home, on the other hand, manage twice as much time – more than two and a half hours – looking after their offspring, according to the Organisation for Economic Co-operation and Development.

　　Critics say the pressure on women to work long hours, and leave their offspring in the hands of nurseries or childminders, is putting the well-being of their children at risk.

　　The study also reveals that, despite the fact that more and more modern mothers go out to work, the burden of childcare still falls on them - even if their husband is not in work. A father who is not in work tends to spend just 63 minutes a day looking after his child - 18 minutes less than a mother who goes out to work. Working fathers spare less than three quarters of an hour with their children.

XI'AN - China's conservation work for the endangered crested ibis（朱鹮）is facing new challenges, including an increasing mortality rate due to inbreeding, and the conflict between the need to expand natural habitats and local communities' economic interests, bird experts have warned.

The crested ibis, once widespread in Japan, China, Russia and the Korean Peninsula, almost became extinct in the first half of the 20th century.

Before 1981, when seven crested ibis were accidentally found in Yangxian county, in Northwest China's Shaanxi province, academics thought the species had been extinct in China for almost 17 years.

Due to the huge effort put into species protection since 1981, the number of crested ibis in China has risen to an estimated 1,617, including 997 in the wild, the State Forestry Administration said at a meeting on crested ibis protection in Xi'an on Monday.

However, although the ibis population exceeds 1,000, the birds are still not free from the threat of extinction, said Fang Shengguo, director of the State Conservation Center for Gene Resources of Endangered Wildlife at Zhejiang University.

“Ornithologists used inbreeding in the early stages of protection so that numbers of the precious birds could increase quickly, but that method had consequences,” Fang said.

"Studies have proved that as a result of inbreeding, crested ibis have the lowest genetic diversity of all endangered birds," Fang said.

"It means a high mortality rate and more physical defects for hatched chicks."

“The government should collect genetic information from all crested ibis and establish a genetic database as soon as possible, then design a scientific mating plan for the species,” Fang said.

So far, about 90 percent of crested ibis live in Shaanxi province, and fewer than 140 ibis live in three zoos in other parts of the country, including Beijing Zoo, according to Liu Dongping, an assistant researcher at the National Bird Banding Center of China, which is affiliated to the Chinese Academy of Forestry.

The bird has lost the ability to migrate, he said, adding that if an unexpected natural disaster occurred in Shaanxi province or an infectious disease spread through the area, the ibis population could be greatly reduced.

Experts also warned that the increased population of ibis, whether in the wild or in captivity, requires a larger and more varied natural habitat.

Rampant hunting, the massive loss of habitat caused by deforestation and the overuse of pesticides, which killed aquatic insects on which the ibis feed, are believed to be the main reasons for the sharp reduction in the ibis population before 1981.

So, in 1983, a State-level natural reserve was set up in Shaanxi province to protect the bird. But the struggle for living space between human and animal has never stopped, said Lu Baozhong, deputy director of the Shaanxi Crested Ibis Conservation Station.

"For example, ibis often look for loaches in farmers' rice fields. Sometimes their claws trample the rice seedlings. In another case, villagers discovered some land with abundant mineral resources which happened to be a habitat for ibis," said Lu, who has devoted 30 years to ibis protection.

A long-term win-win solution for ibis and local communities needs to be developed, one that would provide ecological compensation for local residents, Lu said.

I would like to tell you a story about my uncle Theo. He is my oldest uncle, a tall, thin, grey-haired man whose thoughts are always on learning and nothing else. He is quiet, gentle and absent-minded and with about as much sense as a child where money is concerned. Well, he applied a post in Camford University. It was a very good post and there were hundreds of candidates who applied for it, and about fifteen, including Theo, were asked to be interviewed.

    Camford is a very small town; there is only one hotel in it, and it was so full that they had to put many of the candidates two in a room. Theo was one of these, and the man who shared the room with him was a self-confident fellow called Adams, about twenty years younger than Theo, with a loud voice, and a laugh that you could hear all over the hotel. But he was a clever fellow all the same and had a good post in Iscaiot College, Narkover. Well, the Dean, who was the head of the department of the University, and the committee interviewed all the candidates; and as a result of this interview, the number of the candidates was reduced to two, Uncle Theo and Adams. The committee couldn’t decide which of the two to take, so they decided to make their final choice after each of the candidates had given a public lecture in the college lecture-hall. The subject they had to speak on was “The Civilization of the Ancient Summerians”; and the lecture had to be given in three days’ time.

    Well, for these three days Uncle Theo never left his room. He worked day and night at that lecture, writing it out and memorizing it, almost without eating or sleeping. Adams didn’t seem to do any preparation at all. You could hear his voice and his laughter where he had a crowd of people around him. He came to his room late at night, asked Uncle Theo how he was getting on with his lecture, and then told him how he had spent the evening playing bridge, or at the music hall. He ate like a horse and slept like a log; and Uncle Theo sat up working at his lecture.

    The day of the lecture arrived. They all went into the lecture hall and Theo and Adams took their seats on the platform. And then, Theo discovered, to his horror,  that typewritten copy of his speech had disappeared! The Dean said they would call on the candidates on the alphabetical order, Adams first; and the despair in his heart, Theo watched Adams calmly take the stolen speech out of pocket and read it to the professors who were gathered to hear it. And how well he read it! Even Uncle Theo had to admit he couldn’t have read it nearly so eloquently himself, and when Adams finished there was a great burst of applause. Adams bowed and smiled, and sat down.

    Now, it was Theo’s turn. But what could he do? He had put everything he knew into the lecture. His mind was too much upset to put the same thoughts in another way. With a burning face he could only repeat, word for word, in a low, dull voice, the lecture that Adams had spoken so eloquently. There was hardly any applause when he sat down.

    The Dean and the committee went out to decide who the successful candidate was, but everyone was sure what their decision would be. Adams leaned across to Theo and patted him on the back and said, smilingly, “Hard luck, old fellow, but after all, only one of us could win”

    Then the Dean and the committee came back, “Gentlemen”, the Dean said, “the candidate we have chosen is Mr. Hobdell.” Uncle Theo had won! The audience were completely taken by surprise, and the Dean continued, “ I think I ought to tell you how we arrived at the decision. We were all filled with admiration at the learning and eloquence of Mr. Adams. I was greatly impressed. But, you will remember, Mr. Adams read his lecture to us. When Mr. Hobdell’s turn came, he repeated that speech, word by word from memory, though, of course, he couldn’t have seen a line of it before. Now a fine memory is absolutely necessary for this post; and what a memory Mr. Hobdell must have! This is why we decided that Mr. Hobdell was exactly the man we wanted! ”

    As they walked out of the room, the Dean came up to Uncle Theo, who was so confused but so happy that he hardly knew whether he was standing on his head or heels; and as he shook Theo’s hand he said, “Congratulations, Mr. Hobdell! But, my fellow, when you are on our staff, you must be more careful and not leave valuable papers lying about!”

Today is Sunday. The sky is full of sunshine; so does my life. At about 9:00 a.m., I go to the bookstore with my friends. There was a lot of new books. I didn’t know which one to buy, because these books were all useful to me. At last, I chose two. At 10:00, we went to the cinema. The film calling Titanic was very popular. It took us about 3hours to see. Having seen a film, everyone was deeply moved. Some friends even burst into tear. From the story, I understand that love is noble but valuable. That’s a real wonderful film. It is well worth seeing again.

What a happy day! I hope tomorrow I will be even happy!
