Softening agent from PVC cause of asthma and allergic symptoms among children
There is a clear co-variation between allergic symptoms in children and the concentration of softening agents in their homes. This is a finding made by a Swedish-Danish research team in a recently published study financed by Formas, the Swedish Research Council for Environment, Agricultural Sciences, and Spatial Planning. "A great number of... view more... (2004-08-16)
Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. view more (2009-04-20)
Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time that associated dust has been detected. The... view more... (2005-03-30)
Mother's prenatal stress predisposes their babies to asthma and allergy
Women who are stressed during pregnancy may pass some of that frazzlement to their fetuses in the form of increased sensitivity to allergen exposure and possibly future asthma risk. view more (2008-05-19)
SMART-1 search for lunar peaks of eternal light
ESA's SMART-1 mission to the Moon has been monitoring the illumination of lunar poles since the beginning of 2005, about two months before arriving at its final science orbit. Ever since, the AMIE on-board camera has been taking images which are even able to show polar areas in low illumination conditions. Images like these will help identify if... view more...

General Prize Shortlist Announced - Aventis Prizes for Science Books 2002
Schizophrenia, dust, scientific rivalry and life among the baboons of Africa are among the subjects covered in the shortlist for the General Prize of the Aventis Prizes for Science Books 2002. The shortlist for the General Prize, selected from 83 entries submitted this year, is: AEONS by Martin... view more... (2002-05-24)
Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust. view more (2006-06-07)
Dusty old star offers window to our future, astronomers report
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust - a discovery that may provide insights into our own solar system's eventual demise several billion years from now. view more (2005-09-09)

Treasures reborn out of dust
A day at a museum often forms part of vacationers' sightseeing plans. Greece has many famous sites of antiquity, where visitors can admire marble busts and statuary. It has become standard practice to protect the valuable, antique specimens against inquisitive fingers or polluted air by displaying almost indistinguishable, hand-made replicas. In a... view more...

Mobile climate monitoring facility to sample skies in Africa
The U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Program is placing a new, portable atmospheric laboratory with sophisticated instruments and data systems in Niger, Africa, to gain a better understanding of the potential impacts of Saharan dust on global climate. view more (2006-01-19)
Stellar Clusters Forming in the Blue Dwarf Galaxy NGC 5253
Star formation is one of the most basic phenomena in the Universe. Inside stars, primordial material from the Big Bang is processed into heavier elements that we observe today. In the extended atmospheres of certain types of stars, these elements combine into more complex systems like molecules and dust grains, the building blocks for new planets,... view more...

Colors of Quasars Reveal a Dusty Universe
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II). view more (2009-02-26)
The Scientific Case For Human Spaceflight
Forty years ago, on 12 April 1961, the era of human spaceflight dawned when Yuri Gagarin completed a single, 108 minute, orbit of the Earth on board Vostok 1. Exactly 20 years later, on 12 April 1981, the first U.S. Space Shuttle, Columbia, was launched from Cape Canaveral. In April 2001, the Space Shuttle Endeavour is scheduled to begin the... view more... (2001-03-30)
Double-checking for cleanliness
Spotless surfaces are of prime importance in the plastics and metal processing industries, as dust and dirt can impair the function and adhesive properties of parts. A portable measuring device, the KombiSens, can detect both types of contamination. view more (2004-10-25)
Rising tides intensify non-volcanic tremor in Earth's crust

Scientists track impact of Asian dust and pollution on clouds, climate change
Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. view more (2007-04-20)
Worlds in collision
Two terrestrial planets orbiting a mature sun-like star some 300 light-years from Earth recently suffered a violent collision, astronomers at UCLA, Tennessee State University and the California Institute of Technology will report in a December issue of the Astrophysical Journal, the premier journal of astronomy and astrophysics. view more (2008-09-24)
