Big Bang theory saved
An apparent discrepancy in the Big Bang theory of the universe's evolution has been reconciled by astrophysicists examining the movement of gases in stars. view more (2006-10-27)
Helium helps patients breathe easier
It makes for bobbing balloons and squeaky voices, but now helium is also helping people with severe respiratory problems breathe easier. view more (2007-02-02)
'Supersolid' or melted 'superfluid' film: A quantum difference
New calculations support an alternative to "superfluidity" of a solid as the explanation for the behavior of an isotope of helium, 4He, at temperatures approaching Absolute Zero, according to a report in Physical Review Letters. view more (2005-06-16)
Space is dusty, and now astronomers know why
Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study published in Science Express today. view more (2006-06-09)
The colourful demise of a Sun-like star
A brand new image taken with Hubble's Wide Field Planetary Camera 2 shows the planetary nebula NGC 2440 - the chaotic structure of the demise of a star. view more (2007-02-15)
The Invisible Galaxies That Could Not Hide
Astronomers, using the unique capabilities offered by the high-resolution spectrograph UVES on ESO's Very Large Telescope, have found a metal-rich hydrogen cloud in the distant universe. The result may help to solve the missing metal problem and provides insight on how galaxies form. view more (2006-02-16)
Study reconciles long-standing contradiction of deep-earth dynamics
Researchers at Columbia University's Lamont-Doherty Earth Observatory recently resolved a long-standing contradiction about the workings of the deep Earth. view more (2005-08-25)
It whistles; change in pitch tells all in this new sonic gas analyzer
Penn State researchers have developed a prototype sonic gas analyzer that automatically and continuously tracks the concentration of a gas in an air/gas mixture based on changes in pitch. view more (2005-10-20)
Iowa State astronomer helps discover planet that offers clues to Earth's future
An international team of astronomers that includes Steve Kawaler of Iowa State University has announced the first discovery of a planet orbiting a star near the end of its life. view more (2007-09-13)
Glacial pace of erosion was not so slow, new technique shows
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work. view more (2005-12-12)
Sustainable nuclear energy moves a step closer
In future a new generation of nuclear reactors will create energy, while producing virtually no long-lasting nuclear waste, according to research conducted by Wilfred van Rooijen, who will receive his Delft University of Technology PhD degree based on this research subject on Tuesday, 12 December. view more (2006-12-12)
Princeton scientists confirm long-held theory about source of sunshine
Scientists are a step closer to understanding sunshine. A monumental experiment buried deep beneath the mountains of Italy has provided Princeton physicists with a clearer understanding of the sun's heart -- and of a mysterious class of subatomic particles born there. view more (2007-08-21)
New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
Solution to elusive problem
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions. To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and therefore difficult to detect. Freezing... view more... (2003-01-21)
Cosmic dust in terrestrial ice
For the last 30,000 years, our planet has been hit by a constant rain of cosmic dust particles. view more (2006-07-28)
New approach allows closer look at smoker lungs
Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use. view more (2006-05-31)
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)
Cosmologists predict a static universe in 3 trillion years
When Dutch astronomer Willem de Sitter proposed a static model of the universe in the early 1900s, he was some 3 trillion years ahead of his time. view more (2007-05-24)
New MRI technique shows emphysema in asymptomatic smokers
A new imaging method has revealed early signs of emphysema in smokers with no external symptoms of the disease, according to a study published in the June issue of Radiology. view more (2006-05-30)
Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. view more (2005-06-30)
