Flour, cheese and old shrimp shells become new packaging
Imagine throwing out your old shrimp shells after dinner--in a bag made of shrimp shells. In his doctoral dissertation, Mikael G'¤llstedt at the Royal Institute of Technology in Sweden describes how we can make environmentally friendly packing out of garbage. The number of grocery packages is constantly growing. Most packages are made of... view more... (2004-05-06)
Lavas from Hawaiian volcano contain fingerprint of planetary formation
Hikers visiting the Kilauea Iki crater in Hawaii today walk along a mostly flat surface of sparsely vegetated basalt. It looks like parking lot asphalt, but in November and December 1959, it emitted the orange glow of newly erupted lava. view more (2008-06-20)
Glass You Can Build With
The normal structure of metals is crystalline. Glass, on the other hand, is amorphous. But it's possible to make amorphous forms of metal, metallic glasses, which can be remarkably strong, having many properties equal to or better than their crystalline metal cousins. The catch is that bulk metallic glasses are highly susceptible to fatigue, a... view more... (2009-03-24)
Carnegie Mellon Researchers Identify New Drug To Prevent Seizure Progression in Model of Epilepsy
Carnegie Mellon University researchers have identified a new anticonvulsant compound that has the potential to stop the development of epilepsy. The findings are published in the current issue of the journal Epilepsia. view more (2009-05-05)

Phosphate tungsten bronzes have been tested as cathodes in electrochemical lithium insertion cells. view more (2005-11-09)
Scientists create first working model of a 2-qubit electronic quantum processor
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. view more (2009-07-01)
Brain cells help neighboring nerves regenerate
Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons. view more (2008-05-28)
Micro-pump is cool idea for future computer chips
Engineers at Purdue University have developed a tiny "micro-pump" cooling device small enough to fit on a computer chip that circulates coolant through channels etched into the chip. view more (2006-04-27)
Scripps research scientists discover molecular defect involved in hearing loss
Scientists from The Scripps Research Institute have elucidated the action of a protein, harmonin, which is involved in the mechanics of hearing. view more (2009-05-14)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
Researchers discover that gene switches on during development of epilepsy
A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder. view more (2009-04-23)
Improving Fuel Cell Durability: Research into Better Fuel Cell Materials and Designs Starts with Studying Failures
Fuel cells can be expensive and they typically don't last as long as their internal combustion counterparts. view more (2007-11-29)
Scientists Uncover Potential Key to Brain Blood-Flow Disorders
Scientists at the University of Vermont have clarified the cellular process responsible for signaling regional blood flow changes in the brain, thereby uncovering possible causes for such disorders as stroke, migraine, and Alzheimer's disease. view more (2007-01-04)
Researchers create new super-thin laser mirror
Engineers at the University of California, Berkeley, have created a new high-performance mirror that could dramatically improve the design and efficiency of the next generation of devices relying upon laser optics, including high-definition DVD players, computer circuits and laser printers. view more (2007-02-14)
Dominant cholesterol-metabolism ideas challenged by new research
A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL). view more (2007-08-16)
Metabolic acidosis associated with an increased mortality rate
Critically ill patients with metabolic acidosis are twice as likely to die as patients who do not have metabolic acidosis. view more (2006-02-10)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
IBEX spacecraft detects fast neutral hydrogen coming from the moon
NASA's Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of very fast hydrogen atoms coming from the moon, following decades of speculation and searching for their existence. view more (2009-06-19)
Mechanism discovered in worm defecation identifies potentially widespread cell-to-cell communication
The focus of two recent Nobel prizes, a species of roundworm has made possible another advance in the understanding of how cells talk to one another, according to a study published online Feb. 21 in the journal Current Biology. view more (2008-02-22)
New battery technology helps stimulate nerves
With the help of new silicon-based compounds, scientists - and patients - are getting a significant new charge out of the tiny lithium batteries used in implantable devices to help treat nervous system and other disorders. view more (2005-10-05)
