Shanghai Jiaotong University students won a programming competition this month, once again defeating colleges like Stanford. Jillian Murphy

From The New York Times:

SHANGHAI — With its sterling reputation and its scientific bent, Shanghai Jiaotong University has the feel of an Ivy League institution.

The university has alliances with elite American ones like Duke and the University of Michigan. And it is so rich in science and engineering talent that Microsoft and Intel have moved into a research park directly adjacent to the school.

But Jiaotong, whose sprawling campus here has more than 33,000 students, is facing an unpleasant question: is it a base for sophisticated computer hackers?

A Steady Buzz of Changes

From Technology Review:

Is there time for Google to salvage its social network after a botched launch?

Since the troubled launch of Google's new social network earlier this month, the company has introduced a flurry of changes in an effort to address user confusion and privacy concerns. Google says its engineers have been working nonstop to adjust features and incorporate user feedback. But the product, called Buzz, has already spurred criticism, a complaint to the FTC, and a lawsuit. While experts say there's no way to undo the damage done by botched privacy controls in the first few days after launch, some believe the service still has a chance to redeem itself.

Healing Touch: The Key To Regenerating Bodies



From New Scientist:

YOU started life as a single cell. Now you are made of many trillions. There are more cells in your body than there are stars in the galaxy. Every day billions of these cells are replaced. And if you hurt yourself, billions more cells spring up to repair broken blood vessels and make new skin, muscle or even bone.

Even more amazing than the staggering number of cells, though, is the fact that, by and large, they all know what to do - whether to become skin or bone and so on. The question is, how?

Climate Change Could Be Accelerated By 'Methane Time Bomb'

From The Telegraph:

Climate change could be accelerated dramatically by rising levels of methane in the Earth’s atmosphere, scientists will warn today.

Atmospheric levels of the greenhouse gas, which is as much as 60 times more potent than carbon dioxide, appear to have risen significantly for the past three years running, scientists say.

Experts have long feared that vast amounts of the natural gas trapped in the frozen tundra of the Arctic could be unlocked as the permafrost is melted by rising temperatures, triggering a "methane time bomb" that could cause temperatures to soar.

Olympic timing a high-tech affair

From CNET:

VANCOUVER, British Columbia--Less than a century ago, the timing of downhill skiing required someone at the top and bottom of the run, each with a stopwatch synchronized to the time of day.

Every few skiers, the timer at the top would send down a piece of paper with the start times of the last few skiers and then some math would ensue, eventually resulting in the time of the run being calculated.

(Image: Jim Shryne/USAF)


From New Scientist:

A laser-toting Boeing 747 blasted two missilesMovie Camera out of the sky earlier this month, but despite this apparent success the Pentagon is going back to the drawing board in its search for an anti-missile laser weapon.

The ABL's problem is that it can't deliver enough power over enough distance to be genuinely useful, so the culmination of a project begun in 1996 and costing an estimated $5 billion will be to downgrade the ABL to a "testbed". It will be handed over by the Missile Defense Agency to the US air force for general research use.
