DSOM Post The Problem With Cooling Molecules

------------------------------------------

From http://www.physorg.com/

Cooling molecules with lasers is harder than cooling individual atoms with lasers. The very process of laser cooling, in which atoms are buffeted by thousands of photons, was thought by many to be impossible for molecules since photons, instead of slowing and cooling the molecules, could actually excite internal motions such as rotations and vibrations.

What a Gas! Hubble Takes a Snap of the Past

LOS ANGELES: Scientists have found the most distant space object yet observed: a galaxy born just 500 million years after the Big Bang.

NASA, ESA, G. Illingworth

Astronomers using ESO's Very Large Telescope (VLT) have now measured the distance to the most distant galaxy so far, UDFy-38135539 (the faint object shown in the excerpt on the left).

It is seen here in a Hubble Space Telescope photo and is about 13.1 billion light-years away.

An ancient galaxy has broken the record for the most distant point in the sky known to date, with its light taking roughly 13.1 billion years to reach Earth -- -- also making it the oldest known thing in the universe.

DSOM Post Physicists Eye Graphene-Based Spin Computer

Knowing that Tunneling Has Great Importance in the Big Bang Theory,

I thought this study was intereting...

Ugggh.....204 Character in the Link? Really, Is That Necessary....

Even CNN, the biggest News delivery system in the World,

doesn't have to fillet it's folder structure that much...

Try 26 characters please. Get Real.

DSOM Post: Scratched Glasses Give Perfect Vision for Any Eyesight

From

DITCH Those Bifocals

You might soon be wearing spectacles whose lenses allow you to see clearly regardless of how long or short-sighted you are.

With age, the lenses in our eyes often lose the ability to change shape enough to focus light from near objects onto the retina - a condition called presbyopia. This leaves people who were already short-sighted unable to focus on either near or distant objects. Bifocals offer a solution by having two lenses in the same frame, but users must get used to tilting their head up or down to switch focus.
