- Astronomers weigh 200-million-year-old baby galaxies
10-25-2006 · EurekAlert!
Astronomers have taken amazing pictures of two of the most distant galaxies ever seen. The ultradeep images, taken at infrared wavelengths, confirm for the first time that these celestial cherubs are real. The researchers are now able to weigh galaxies and determine their age at earlier times than ever before, providing important clues about the evolutionary origins of galaxies like our Milky Way.

- The world's oldest bacteria
08-27-2007 · EurekAlert!
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. The exceptional discovery can lead to a better understanding of the ageing of cells and might even cast light on the question of life on Mars.

- 'Tornadoes' are transferred from light to sodium atoms
11-09-2006 · EurekAlert!
For the first time, tornado-like rotational motions have been transferred from light to atoms in a controlled way at NIST. The new quantum physics technique can be used to manipulate Bose-Einstein condensates, a state of matter of worldwide research interest and possibly used in quantum information systems.

- Strontium atomic clock demonstrates super-fine 'ticks'
11-30-2006 · EurekAlert!
Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA (a joint institute of NIST and the University of Colorado at Boulder) have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.

- Discovery of new family of pseudo-metallic chemicals
04-24-2007 · EurekAlert!
A new discovery by a University of Missouri-Columbia research team, published in Angewandte Chemie, the journal of the German Society of Chemists, allows scientists to manipulate a molecule discovered 50 years ago in such as way as to give the molecule metal-like properties, creating a new, "pseudo" element. The pseudo-metal properties can be adjusted for a wide range of uses and might change the way scientists think about attacking disease or even building electronics.

- Scientists discover important beauty secret for balanced skin color and tone
08-22-2007 · EurekAlert!
In the timeless quest for healthier, younger looking skin, scientists made an important discovery with implications ranging from helping doctors develop more natural looking bioengineered skin grafts to helping cosmetics companies develop new products for the "perfect" sunless tan. The research study, published in The FASEB Journal's September print issue, shows for the first time how to manipulate skin tone and color using cells previously thought to play no significant role in this function.

- Smoking linked to sleep disturbances
02-04-2008 · EurekAlert!
New research in the journal Chest shows that cigarette smokers are four times as likely as nonsmokers to report feeling unrested after a night's sleep. Smokers also spend less time in deep sleep and more time in light sleep than nonsmokers. Researchers speculate that the stimulating effects of nicotine could cause smokers to experience nicotine withdrawal each night, which may contribute to disturbances in sleep.

- Genes identified to protect brassicas from damaging disease
11-01-2007 · EurekAlert!
Scientists have identified a new way to breed brassicas, which include broccoli, cabbage and oilseed rape, resistant to a damaging virus. Their discovery has characterised a form of resistance that appears to be durable, broad-spectrum and unlikely to be overcome by the virus over time. Turnip mosaic virus is an economically devastating virus that infects a wide range of cultivated plants, but especially brassicas.

- Largest, brightest supernova ever seen may be long-sought pair-instability supernova
05-07-2007 · EurekAlert!
UC Berkeley astronomers Nathan Smith and David Pooley report the most luminous supernova ever detected, the explosion of a super-massive star in a galaxy 250 million light years away. The scientists estimate the star was 150 times larger than our sun, and that it exploded via an entirely new mechanism never before observed. Unlike other massive supernovas, this so-called pair instability supernova left behind no black hole.
