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 thought 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 of 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 of an area,” she said.
Yet scientist 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 Sai.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial (商业的) world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial (金钱的) considerations.
Helen Lee took a 70%cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects (前景) of a commercial return, and Lee’s is one of them.
The influence of a salary cut is probably less serious for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a medicine company before returning to university as a post doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual chances.
Higher up the ladder, where a pay cut is usually more important, the demand for scientists with a wealth of experience in industry is forcing universities to make the change to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential (潜力) in the job market than someone who has spent all their time on a narrow research project.”
【小题1】By “a one-way street” in Paragraph 1, the author means ______.

A.university researchers know little about the commercial world
B.few university professors are willing to do industrial research
C.few industrial scientists would leave to work in a university
D.there is little exchange between industry and academia
【小题2】The underlined word “deterrent” most probably refers to “something that ______”.
A.helps to move the trafficB.attracts people’s attention
C.brings someone a financial burdenD.keeps someone from taking action
【小题3】What was Helen Lee’s major consideration when she changed her job in the middle of her career?
A.Less work hours.
B.More freedom to choose research fields.
C.Better prospects of a commercial return.
D.Her preference for the lifestyle on campus.
【小题4】What can industrial scientists do when they come to teach in a university?
A.Make its research more practical.
B.Develop its students’ potential in research.
C.Help it to obtain financial support from industry.
D.Increase its graduates’ competitiveness in the job market.
