The other big bang?

The theory about space rocks wiping out Ice Age species just got another boost: It turns out the first human inhabitants may have also been hit. Rare "nano-sized diamonds" that form under extremely hot fires are evidence that space rocks hit the North American continent about 13,000 years ago. Unfortunately, some pygmy mammoth (a smaller version of the woolly mammoth) and a group called the Clovis people happened to be in the line of fire. The galactic slam, plus "overhunting and climate change," created what one researcher called a "perfect storm" that wiped out the Ice Age population. The findings swelled searches on Yahoo! for the prehistoric "clovis people," so named because of artifacts first found in Clovis, New Mexico.

Big Bang:Transformer glitch shuts down biggest atom smasher

Transformer glitch shuts down biggest atom smasher



GENEVA - The world's largest particle collider malfunctioned within hours of its launch to great fanfare, but its operator didn't report the problem for a week.

In a statement Thursday, the European Organization for Nuclear Research reported for the first time that a 30-ton transformer that cools part of the collider broke, forcing physicists to stop using the atom smasher just a day after starting it up last week.

The faulty transformer has been replaced and the ring in the 17-mile circular tunnel under the Swiss-French border has been cooled back down to near zero on the Kelvin scale — minus 459.67 degrees Fahrenheit — the most efficient operating temperature, said a statement by CERN, as the organization is known.

When the transformer malfunctioned, operating temperatures rose from below 2 Kelvin to 4.5 Kelvin — extraordinarily cold by most standards, but warmer than the normal operating temperature....article
