Proton's party pals may alter its internal structure
A recent experiment at the Department of Energy's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structure. view more (2009-11-19)
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)
Hubble sees multiple star generations in a globular cluster
Hubble's observations of the massive globular cluster NGC 2808 provide evidence for three generations of stars that formed early in its life. This is a major upset for conventional theories that propose a single period of star birth. view more (2007-05-03)
Cosmic dust in ice cores sheds light on Earth's past climate
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes in the... view more...

Jupiter's rocky core bigger and icier, model predicts
Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms. view more (2008-11-26)
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)
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)
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)
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)
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)
How To Eliminate Nitrogen Narcosis Effects
We do not feel the nitrogen of air, and scientists do not believe that under normal pressure nitrogen can affect human organisms. However, being under water or in the altitude chamber nitrogen produces a different effect. Once the pressure is increased about four times, simulating the pressure which exists at the 30- meter depth, the first signs... view more... (2003-07-11)
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)
From galaxy collisions to star birth: ISO finds the missing link
Data from ISO, the infrared observatory of the European Space Agency (ESA), have provided the first direct evidence that shock waves generated by galaxy collisions excite the gas from which new stars will form. The result also provides important clues on how the birth of the first stars was triggered and speeded up in the early Universe. By... view more... (2005-03-29)
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)
High-frequency cryocooler is tiny, cold and efficient
A new cryogenic refrigerator has been demonstrated at the National Institute of Standards and Technology (NIST) that operates at twice the usual frequency, achieving a long-sought combination of small size, rapid cooling, low temperatures and high efficiency. view more (2007-02-16)
MSU researcher adds to knowledge of how early stars, galaxies formed
Research by a Michigan State University scientist sheds new light on how stars and galaxies were formed back in the early days of the universe - some 13 billion years ago. view more (2009-07-10)
Study gives clues to increasing X-rays' power
Three-dimensional, real-time X-ray images of patients could be closer to reality because of research recently completed by scientists at the University of Nebraska-Lincoln and a pair of Russian institutes. view more (2009-06-16)
Were the first stars dark?
Perhaps the first stars in the newborn universe did not shine, but instead were invisible "dark stars" 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter, a University of Utah study concludes view more (2007-12-03)
'Vortex lattices' may help explain material defects
What do you get when you superimpose a rotating pattern of intersecting laser beams on a spinning cloud of ultracold atoms in a thin gas? Pretty pictures, for one thing-but also a new method that could be used to simulate why and how defects arise in superconductors, important materials that are difficult to study directly. view more (2006-12-26)
Astronomers discover new radio signal using large balloon
A team of NASA-funded scientists, including two from UC Santa Barbara, have discovered cosmic radio noise that they find completely unexpected and exciting. view more (2009-01-08)
