Scientists have discovered a special biological behavior in dolphins(海豚) that could lead to a treatment for late-onset diabetes(晚发的糖尿病) in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.

The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.

If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity(肥胖).

The tissues of people with type 2 diabetes have become resistant to insulin(胰岛素) so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys(肾脏) and nerves and contribute to 5% of all deaths, according to the World Healthy Organization.

Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analyzed 1,000 blood samples(样本) from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism(新陈代谢)changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.

“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.

For this part of “Tips for Applying to US Colleges” we visited Shenandoah University in the US state of Virginia. It is a private institution with about 4,000 students from 55 countries. We asked them some of questions about adapting to American culture and writing admissions essays.

A. How can I succeed in applying to American colleges?

B. What advice do you have for writing an admission essay?

C. Why should I study abroad?

D. What are some difficulties students have adapting to US culture?

E. What about religious life on campus?

F. What are some academic difficulties foreign students face?

1._______________

I think everyone should travel and live and work and study abroad. I think it’s great for a lot of reasons. One—of course you’re going to learn something about other people. And that’s good, we should know about other people because we live in what is called a “globalized world.” More importantly, you’re going to learn something about yourself. You’re going to learn about how strong you really are. You’re going to learn that you have capabilities that you never knew you had. When you’re in another place and maybe you don’t even speak the language very well, you’re gonna find that you still figure a way to communicate. Maybe you can do something even bigger and even more, a little more challenging.

2._______________

Students often misunderstand policies that we have here. And I think sometimes that can get students into trouble. I think we have had some issues with students who have worked a little too closely together for our professors’ level, and so that has created some challenges at times for those students. In terms of that, kind of, power structure between a professor and a student here, I would say our environment, our culture here at Shenandoah, there’s not a whole lot of that. I mean it’s very much of an environment where that sort-of barrier between professor and student is a little less than what it might be the case at other institutions. So that part of it is not as much of an issue.

3._______________

I would say the important thing is to also be authentic. Be yourself. Most students are reading a lot of essays and after a while they start to kind of sound the same. And so you want to give that person the curiosity to know you. And you’re special. You’re different than everybody else that’s applying. So, I think if you can try your best. Of course, there are things you think, “I need to say these things because that’s what they want to hear.” Certainly if there are topics that they are asking you to respond to, you want to do that. But, to try as much as you can to give the person who’s reading your essay an idea of who you are and what makes you unique. I think that would be my main advice.

4.______________

We are open to all religions, of all backgrounds. I mean we have a Catholic campus ministry, we have a Muslim student association, and we have a Jewish student association. We really do aim to be inclusive of all students regardless of their religious beliefs. Students certainly feel included, they certainly feel comfortable being here, you know, they’re—regardless of whatever their religious beliefs might be and even if that’s—even if they don’t have any religious beliefs. We certainly have students who are that way too.

5._______________

A lot of it breaks down to different communication styles. Some are what we would call “high context cultures.” It means that you shouldn’t have to say what the problems is. Some cultures like American culture is very low context. We expect you say exactly what you mean. And if you didn’t say it, we probably don’t know it’s a problem. So sometime we—I have seen some students maybe have some roommate issues because the international student is upset with something and they assume the roommate must know that they’re upset. But the roommate—the American roommate—maybe doesn’t even know that it’s a problem. And one of the things I would caution new international students is that it's kind of an American way to be very open and friendly with everyone.
