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...

Electric sand findings could lead to better climate models
Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. view more (2008-01-08)
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)
Dust clouds in cosmic cycle
It has been a mystery for astronomers how certain dying stars have their colossal quantities of material blown out into the universe and shrink into objects called "white dwarves". view more (2007-04-05)
The Definitive Beta-blocker For Heart Failure? (pp 2, 7, 14)
Results of a European study in this week's issue of THE LANCET suggest that the beta-blocker carvedilol offers substantial survival benefit compared with another widely-used beta blocker for the treatment of chronic heart failure. Beta blockers reduce death in patients who are also taking diuretics and ACE inhibitors for chronic heart failure. In... view more... (2003-07-02)
'It might be life, Jim...', physicists discover inorganic dust with lifelike qualities
Could extraterrestrial life be made of corkscrew-shaped particles of interstellar dust? Intriguing new evidence of life-like structures that form from inorganic substances in space are revealed today in the New Journal of Physics. view more (2007-08-15)
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...

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)
Life And Death In Space
Ever since its formation at the birth of the Solar System, some 4570 million years ago, planet Earth has resembled a giant bulls-eye in space, a target for asteroids and comets of all shapes and sizes. Clearly, this violent history has influenced the planet's surface and atmosphere, as well as the evolution of life. Some impactors bring water and... view more... (2003-04-05)
Space shuttle science shows how 1908 Tunguska explosion was caused by a comet
The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research. view more (2009-06-25)
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)
Highly sensitive weather radar a gain for climate research
TU Delft has taken a new weather radar system into use, the 'Drizzle Radar', which can observe even the lightest of drizzles. This is an enormous gain for climate researchers and is attracting international attention. view more (2007-08-27)
Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found. view more (2005-08-26)
A blue ring around the planet Uranus
The outermost ring of the planet Uranus turns out to have a bright blue color, according to a report in the April 7 issue of the journal Science. view more (2006-04-07)
Solar Games at Paranal
Cerro Paranal, home of ESO's Very Large Telescope, is certainly one of the best astronomical sites on the planet. Stunning images, obtained by ESO staff at Paranal, of the green and blue flashes, as well as of the so-called 'Gegenschein', are real cases in point. view more (2008-05-05)
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)
Cold Dust At The Heart Of TheUniverse
The Universe contains vast quantities of very cold dust and gas; from the relatively dense regions where young stars are born to the most distant galaxies, still in the process of forming after the Big Bang. The new SCUBA instrument, conceived, designed and built at the Royal Observatory, Edinburgh and installed on the James Clerk Maxwell... view more... (1996-06-28)
Ice has a starring role - CMD19/CMMP with The Physics Congress 2002
When even moderately hot stars like our Sun have surface temperatures of around 6,000°C, it is hard to imagine that ice plays an important part in their formation. But that`s exactly what astrophysicists have recently discovered by turning to surface scientists for help. At the Condensed Matter conference on Monday 8 April, part of the... view more...

Discovered after 40 years: Moon dust hazard influenced by Sun's elevation
In the 1960s and 1970s, the Apollo Moon Program struggled with a minuscule, yet formidable enemy: sticky lunar dust. Four decades later, a new study reveals that forces compelling lunar dust to cling to surfaces -- ruining scientific experiments and endangering astronauts' health --change during the lunar day with the elevation of the sun. view more (2009-04-20)
Emphysema severity directly linked to coal dust exposure
Coal dust exposure is directly linked to severity of emphysema in smokers and nonsmokers alike, according to new research from the National Institute for Occupational Safety and Health (NIOSH). view more (2009-07-24)
