Sticky dust fingers the culprits
EMBARGOED UNTIL WEDNESDAY 5 NOVEMBER 19:00 HRS GMT NANOPARTICLES could give police the clearest fingerprints yet. Officers search for prints by dusting a crime scene with fluorescent powder. This sticks to the oily residue left by the fingertip, showing up the whorls and ridges. But sometimes the prints are not clear enough to finger a suspect.... view more... (2003-11-05)
The dark matter of the universe has a long lifetime
New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe - dark matter. The research has just been published in the scientific journal Physical Review Letters. view more (2007-10-02)
Desert dust alters ecology of Colorado alpine meadows
Accelerated snowmelt--precipitated by desert dust blowing into the mountains--changes how alpine plants respond to seasonal climate cues that regulate their life cycles. view more (2009-06-30)
Magnetic nanoparticles assembled into long chains
Chains of 1 million magnetic nanoparticles have been assembled and disassembled in a solution of suspended particles in a controlled way. view more (2005-10-21)
Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth. view more (2009-11-05)
How Life Originated In Space
Life originated on the Earth more than 3.5 billion years ago. However, the scientists are still disputing over the possible sources of the life origin. The matter is that life on our planet evolved from the molecular level to the level of bacteria organisms within 0.5 - 1 billion years, this period being very short for such an important... view more...

New particles get a mass boost
A sophisticated, new analysis has revealed that the next frontier in particle physics is farther away than once thought. New forms of matter not predicted by the Standard Model of particle physics are most likely twice as massive as theorists had previously calculated, according to a just-published study. view more (2007-10-02)
In the first second of Creation
At the very beginning of the Universe both forms of matter existed in equal amounts. They should have cancelled themselves out leaving just energy. But, within a second, something happened to ensure that matter prevailed - and that the Universe could develop in the way that it did. BaBar should shed light on that critical event 15 billion years... view more... (1999-06-11)
Scientists crack open stellar evolution
Using 3D models run on some of the fastest computers in the world, Laboratory physicists have created a mathematical code that cracks a mystery surrounding stellar evolution. view more (2006-10-27)
Evidence of liquid water in comets reveals possible origin of life
Comets contained vast oceans of liquid water in their interiors during the first million years of their formation, a new study claims. view more (2009-07-31)
Will The Leonids Go Out With A Bang?
Anyone willing to brave the early morning cold on 19 November may be rewarded with one of Nature's most spectacular firework displays - a major meteor storm. This year's Leonid meteor shower is expected to provide the last great storm for at least 30 years, and possibly the biggest in the 21st century. With meteor numbers predicted to reach or... view more... (2002-11-15)
LSU scientist finds evidence of 'rain-making' bacteria
Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. view more (2008-02-29)
Better composites through right shape of particles
The shape of the small clay particles in polymer-clay composite materials can determine the stiffness, strength and oxygen permeability of the material. The size of the particles determines the sheen and transparency. These are conclusions from the PhD research project of Martin van Es. He will receive his degree at TU Delft on 12 November.... view more... (2001-11-08)
'Hidden' Milky Way deuterium found
Scientists using NASA's Johns Hopkins University-operated Far Ultraviolet Spectroscopic Explorer satellite have learned that far more "heavy" hydrogen remains in our Milky Way galaxy than expected, a finding that could radically alter theories about star and galaxy formation. view more (2006-08-15)
Astronomers discover the wake of a planet around a nearby star
An international team of astronomers today report the discovery of a huge distorted disk of cold dust surrounding Fomalhaut - one of the brightest stars in the sky. The most likely cause of the distortion is the gravitational influence of a Saturn-like planet at a large distance from the star tugging on the disk. This provides some of the... view more...

Astronomers use gamma-ray burst to probe star formation in the early universe
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. view more (2009-01-07)
At that star, turn left!
Our bodies contain proteins that are made of smaller molecules that can be either left- or right-handed, depending upon their structure. Regardless of which hand we use to write, however, all human beings are `left-handed` at the molecular level. Life on Earth uses the left-handed variety and no one knows how this preference crept into living... view more... (2002-10-17)
The ones that get away
Researchers funded by the National Science Foundation (NSF) have found evidence that particles of lead solder used in plumbing may have sickened two Greenville, N.C., children, in one case at a child's home and in the other case, at a private daycare center. view more (2006-06-30)
Virginia Tech researcher reports nano-particle dispersion technique improves polymers
There is a lot of excitement about incorporating nano particles into polymers because of the ability to improve various properties with only a small percent of the particles. view more (2005-08-30)
Auger Observatory links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration, which includes New York University Physics Professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. view more (2007-11-09)
