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)

Gas explosions: A new way to study phantom traffic jams
A University of Alberta researcher has devised a new theoretical approach to studying phantom traffic jams. Normally a traffic tie-up happens when vehicles reach a bottleneck and traffic flow is reduced, or in the case of an accident, halted completely.   view more (2009-06-09)

Pinning down the fleeting Internet: Web crawler archives historical data for easy searching
The Internet contains vast amounts of information, much of it unorganized. But what you see online at any given moment is just a snapshot of the Web as a whole -- many pages change rapidly or disappear completely, and the old data gets lost forever.    view more (2008-11-18)

On the path to metallic hydrogen
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor.   view more (2009-08-04)

Seismic response to natural gas anomalies in crystalline rocks
The research done at the Chinese Academy of Geological Sciences has shown that after geochemical experiments, the porosity of crystalline rocks in the middle crust increases sharply due to water-rock interaction.   view more (2008-11-05)

Scientists find black hole's 'point of no return'
Scientists have found new evidence that black holes are performing the disappearing acts for which they are known.   view more (2006-01-11)

New study examines effects of Graniteville, S.C., chlorine gas disaster
A new study examining the aftereffects of a chlorine gas disaster in a South Carolina town gives larger metropolitan areas important insight into what to expect and how to prepare emergency response systems for an accidental or terrorist release of the potentially deadly gas. The study is now available in the January 2009 issue of the American... view more... (2008-12-29)

Scientists Find Good News About Methane Bubbling Up From the Ocean Floor Near Santa Barbara
Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara.   view more (2007-12-21)

Laser analyses fuel flame
In a project from the Technology Foundation STW, researcher Roger Evertsen has introduced a new method for measuring the composition of fuel flames. The technique makes use of laser light and is not only quick but also extremely sensitive.   view more (2002-11-15)

Music of the black holes: they all play the same tune
Astronomers at the University of Southampton have uncovered a remarkable connection between the monstrous black holes residing at the hearts of distant galaxies and their comparatively tiny cousins which inhabit star systems in our own Milky Way: they are playing the same tunes. Dr Phil Uttley presents these findings in a talk called `The music of... view more... (2002-04-04)

Ideas on gas-giant planet formation take shape
Rocky planets such as Earth and Mars are born when small particles smash together to form larger, planet-sized clusters in a planet-forming disk, but researchers are less sure about how gas-giant planets such as Jupiter and Saturn form.   view more (2006-03-23)

Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions.   view more (2007-01-31)

Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL).   view more (2008-12-12)

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)

First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by... view more...

Miscounting bioenergy benefits may increase greenhouse gas release
A fixable error in the way carbon is counted in current U.S. climate legislation and in the Kyoto Protocol could undermine efforts to reduce greenhouse gas emissions by using biofuels, says a premier group of national environmental and land use scientists.   view more (2009-10-23)

New Hypothesis Of The Tunguska Explosion
The event which occurred almost a hundred years ago in Podkamennaya Tunguska has drawn scientists` attention again. What actually exploded at that time in the remote taiga, the power of explosion being equal to the 50-megaton H-bomb? The hypothesis that it was a meteorite or any other extraterrestrial object has not quite satisfied inquisitive... view more... (2002-08-23)

Novel temperature calibration improves NIST microhotplate technology
Researchers at the National Institute of Standards and Technology (NIST) have developed a new calibration technique that will improve the reliability and stability of one of NIST's most versatile technologies, the microhotplate.   view more (2009-08-12)

MIT gas sensor is tiny, quick
Engineers at MIT are developing a tiny sensor that could be used to detect minute quantities of hazardous gases, including toxic industrial chemicals and chemical warfare agents, much more quickly than current devices.   view more (2008-01-14)
