A Penn physics study: Of traffic jams, beach sands and the zero-temperature jamming transition
Researchers in condensed matter physics at the University of Pennsylvania and the University of Chicago have created an experimental and computer model to study how jamming, the physical process in which collections of particles are crammed together to behave as solids, might affect the behavior of systems in which thermal motion is important,... view more...

Technique measures heat transport in the Earth's crust
Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet. view more (2009-03-31)

Physicists see similarities in stream of sand grains, exotic plasma at birth of universe
Streams of granular particles bouncing off a target in a simple tabletop experiment produce liquid-like behavior also witnessed in a massive research apparatus that simulates the birth of the universe. view more (2007-11-07)
Protein pulling -- Learning how proteins fold by pulling them apart
Rice University physicists have unveiled an innovative way of finding out how proteins get their shape based on how they unfold when pulled apart. view more (2007-07-20)
EL NIÃ'O: CAUSAL FACTOR OF CHOLERA IN BANGLADESH
A study by a climatologist of the Climate Research Group at the Barcelona Science Park and member of the Department of Ecology at Barcelona University, Xavier Rod'³, together with researchers at various universities in the United States and Great Britain provides evidence that the cholera epidemics in Bangladesh are favoured by meteorological... view more...

New Research Turns Sewage Farms into Power Plants
Researchers at the University of Warwick's Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power. University of Warwick researcher Dr Ashok Bhattacharya and his team are part of a Europe wide consortium that have cracked the problem of how to extract very pure levels... view more... (2002-04-29)
Hybrid semiconductors show zero thermal expansion; could lead to hardier electronics and optoelectronics
The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity - and not incidentally, ruin the chip. view more (2007-12-20)
Theory predicts aging process in DVDs, plexiglas, other polymer glasses
Polymer glasses are versatile plastics widely used in applications ranging from aircraft windshields to DVDs. Researchers at the University of Illinois have developed a theory that predicts how these materials age. The theory also explains why motions at the molecular level can have macroscopic consequences. view more (2007-04-24)
NIST posts online database of cryogenic materials properties
In response to numerous inquiries from academia, industry, and other government labs, the National Institute of Standards and Technology (NIST) recently published a new database on the properties of solid materials at temperatures ranging from cryogenic (as low as 4 K, which is -269 degrees C or -452 degrees F) to room temperature. view more (2007-11-09)
Quantum goes massive
An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale. view more (2009-07-16)
Multiple sclerosis damage found in 'normal' brain tissue
The effects of multiple sclerosis (MS) extend beyond visibly affected areas into large portions of the brain that outwardly appear normal, according to a study appearing in the September issue of Radiology. view more (2006-08-29)
UCR scientists manipulate ripples in graphene, enabling strain-based graphene electronics
Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. view more (2009-07-27)
Nanoscale study gives new insight into heat transfer in biological systems
One of the first things we learn in chemistry class is that solids conduct heat better than liquids. But a new study suggests that in nanoscale materials, this is not necessarily the case. view more (2005-10-21)
Preservation of fresh-cut vegetables; a producer's and consumer's sake
In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the '80s in the UK. Their market is yearly increasing with 25% in West Europe. Packaging fresh-cut... view more... (2002-03-19)
Argonne breakthrough may revolutionize ethylene production
A new environmentally friendly technology created by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory may revolutionize the production of the world's most commonly produced organic compound, ethylene. view more (2008-02-06)
Nanotube forests grown on silicon chips for future computers, electronics
Engineers have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. view more (2007-10-02)
Smoking during pregnancy increases risk of SIDS
A new study provides the most direct evidence that there exists a causal link between smoking during pregnancy and Sudden Infant Death Syndrome (SIDS). view more (2008-05-30)
Ceramic research reaches new heights
Materials scientists at the University of Wales Aberystwyth (UWA) are taking ceramics to new heights in order to determine the structure and stability of the materials which are used to construct aeroplane engines and the tiles for the space shuttle. Dr Rudi Winter and colleagues from the Department of Physics at UWA are using a unique... view more... (2002-03-05)
Measuring the immeasurable: New study links heat transfer, bond strength of materials
The speed at which heat moves between two materials touching each other is a potent indicator of how strongly they are bonded to each other, according to a new study by researchers at Rensselaer Polytechnic Institute. view more (2009-04-14)
