Earthquake threatens Chinese students US applications

International Herald Tribune: Millions of students across Asia have been inconvenienced by the rupture of two undersea data transmission cables in Tuesday's earthquake in Taiwan. Because of the quake, Internet speeds remained slow — and in some areas nonexistent — in Taiwan, Hong Kong, Japan, China, Singapore and South Korea. It is expected to take weeks to fully repair the links.

According to the IHT, Beijing's China Service Center for Scholarly Exchange, a company that helps prepare applications for students looking to study abroad, said that about 300 of its clients weren't able to file applications — including some facing a Jan. 1 deadline because of the disruption. Some students are using mobile phones to try and submit their applications to US universities.

Review of the year: Global warming

The Independent: During the past year, scientific findings emerged that made even the most doom-laden predictions about climate change seem a little on the optimistic side. And at the heart of the issue is the idea of climate feedbacks - when the effects of global warming begin to feed into the causes of global warming. Feedbacks can either make things better, or they can make things worse. The trouble is, everywhere scientists looked in 2006, they encountered feedbacks that will make things worse - a lot worse.

US India nuclear technology deal undermined by President Bush

WhirlView: The legislation that President Bush signed on the US India nuclear technology last week is not an agreement to trade nuclear technology. It waived the laws prohibiting trade with nations that have not signed the Nuclear Nonproliferation Treaty says WhirlView. The bill also lays out a number of requirements that must be met before trade can take place.

What the president didn’t say during the signing ceremony was that he appended a signing statement that undermines changes Congress had made during the bill that strengthened oversight over an technology transfer. Michael Roston at Raw Story details what in the signing statement undermines the law.

Ancient ice shelf snaps and breaks free from the Canadian Arctic

Associated Press: Scientists have discovered that the Ayles Ice Shelf — all 41 square miles of it — broke clear 16 months ago from the coast of Ellesmere Island, about 500 miles south of the North Pole in the Canadian Arctic. The delay in reporting the news came about because satellite imagery of the area have only recently analysed.

Said Warwick Vincent of Laval University, who studies Arctic conditions, "This is a dramatic and disturbing event. It shows that we are losing remarkable features of the Canadian North that have been in place for many thousands of years," Vincent said. "We are crossing climate thresholds, and these may signal the onset of accelerated change ahead."

Iran condemns UN nuclear sanctions

Ft.com: Iran condemned a U.N. sanctions resolution as “a piece of torn paper” that would not scare Tehran and vowed on Sunday to accelerate uranium enrichment work immediately.

The U.N. Security Council voted unanimously on Saturday to impose sanctions on Iran’s trade in sensitive nuclear materials and technology, in an attempt to stop uranium enrichment work that could produce material to be used in bombs.

President Mahmoud Ahmadinejad said those who backed the U.N. resolution, drawn up by Britain, France and Germany but supported unanimously by the Security Council, would soon regret their “superficial act”.

China awards $6 billion nuclear deal

BBC: Westinghouse, the Japanese owned US nuclear-plant builder has won a $8 billion-dollar contract to build four AP1000 nuclear plants in China - two at Sanmen in Zhejiang province, with another two at Yangjiang in Guangdong.

The AP1000 reactor is an advanced pressurised water reactor and the Chinese plants should be operational by 2013. Under the agreement China will also obtain rights to build similar reactors itself as part of its plan to increase nuclear energy capacity from 1% to 5% of its energy market by 2020.

Talk of Satellite Defense Raises Fears of Space War

Washington Post: In a speech last week, Undersecretary of State Robert G. Joseph warned that other nations, and possibly terrorist groups, are "acquiring capabilities to counter, attack and defeat U.S. space systems." As a result, he said, the United States must increase its ability to protect vital space equipment with new technologies and policies. The speech was the first public discussion of the new US space policy that was announced in October. It makes clear that the administration would give the impression of reacting forcefully to any attempt to interfere with U.S. space technology -- whether used by the military or by businesses ranging from paging services and automated teller machines to radio and television providers.

At issue is the failure of 35 Iranian scientists to obtain Egyptian visas for a recent meeting in Alexandria of researchers hoping to work on the Synchrotron Light for Experimental Science and Applications in the Middle East (SESAME) project.

Defense science board seeks consensus on US nuclear arsenal

Washington Post: Walter Pincus reports that in a recently released declassified version of a report on U.S. nuclear capabilities completed earlier this year, the Defense Science Board reported that its task force on the subject concluded "there is a need for a national consensus on the nature and role of nuclear weapons, as well as a new approach to sustaining a reliable, safe, secure and credible nuclear stockpile."

The task force found "most Americans agree that as long as actual or potential adversaries possess or actively seek nuclear weapons or other weapons of mass destruction, the United States must maintain a deterrent to counter possible threats and support the nation's role as a global power and security partner." Beyond that, however, it found "sharp differences."

Hans Kristensen, director of the nuclear information project of the Federation of American Scientists, who first called attention to the science board's report, described it as an effort to "resell" the 2001 Nuclear Posture Review.

Is Sense of Smell Powered by Quantum Vibrations?

SciAm.com: Physicists have now analyzed the proposed mechanism linking a sense of smell with molecular vibrations and deemed it plausible. The new calculations by no means prove the theory, but they give it added legitimacy, says biophysicist and perfumer Luca Turin, who developed the idea. "Most people would probably feel that if it can be done at all, evolution has managed to make use of it." A paper explaining the research appears in Physical Review Letters.

2007 Budget cuts will hit science hard

Science: The Republican Congress adjourned last week without passing a 2007 budget for most federal agencies. The Democratic party, which won control of Congress last November has announced plans to apply current spending levels for the entire fiscal year. This decision will cause research cuts at the Department of Energy's (DOE's) Office of Science, the National Science Foundation (NSF), and the in-house National Institute of Standards and Technology labs says Science.

Scientists surprised about comet's ingredients

Reuters: An examination of the first material plucked from a comet is forcing scientists to rethink the nature of the frigid emissaries from the deepest reaches of our solar system, as well as the early solar system itself.

Reporting their findings on Thursday, scientists who examined tiny grains retrieved by NASA's Stardust spacecraft from comet Wild 2 (pronounced "vilt") in 2004 found the comet, as expected, contained material from outside the solar system.

Gore to scientists: Speak up

Climate Energy debate heats up

Various: More than 100 coal fired power plants will be built over the next 20 years says NPR, and environmentalists are trying to make sure that CO2 emissions will not increase when these plants get built. The Serria Club has persuaded a town in Illionis (check spelling) to close two older coal fired power plants and get 25% of its electricity from wind power in order to stop suing the town over its plans to build a mid-size coal-fired power plant says NPR's Christopher Joyce. Other power companies are looking at carbon "credit" offsets says New York Times reporter Steve Iohr, in which companies are charged a cost for the pollution they produce. As the democrats will be controlling Congress there may even be federal regulation says Elizabeth Shogren and Steve Inskeep at NPR. However, the rise in greenhouse gases will most likely result in open artic seas during the summer by 2040, decades earlier than most scientists had predicted says a new paper by Marika M. Holland, Cecilia M. Bitz and Bruno Tremblay in Geophysical Letters. The open Artic sea will have a major impact on the environment, not only in the Artic, but in Europe and North America as well says Andrew Revkin.
