A Supercharged Metal-Ion Generator
In the electronics industry, thin metal films are deposited on silicon wafers with a sputter gun, which uses energetic ions - atoms with a positive charge - to knock the metal atoms off a target. view more (2009-01-29)
What Happens To The Hormonal System Of Refugees?
The present study is part of a longitudinal study of recently resettled refugees with the aim of learning which factors in their daily life influence health as measured by self-report and stress-responsive hormones. In a group of recently resettled refugees with a high incidence of posttraumatic stress disorder (PTSD), diagnosed by structured... view more... (2002-09-26)
Mechanism for the captation of nutrients in plants- unknown to date
Up to now it was thought that nutrients penetrated the interior of plant cells by means of substance-specific transporters. Nevertheless, researchers at the Agrobiotechnology Institute at the Public University of Navarra have shown that the nutrients (saccharose, amino-acids, etc.) penetrate the cells basically through an "endocitic",... view more...

Cluster hits the magnetic bull's-eye
ESA's spacecraft constellation Cluster has hit the magnetic bull's-eye. The four spacecraft surrounded a region within which the Earth's magnetic field was spontaneously reconfiguring itself. view more (2006-07-19)
Analysis of Spanish flu cases in 1918-1920 suggests transfusions might help in bird flu pandemic
Transfusions with blood products taken from people who had recovered from Spanish influenza may have reduced risk for death and improved symptoms of hospitalized patients who contracted Spanish influenza complicated by pneumonia. Early treatment was superior to later treatment. view more (2006-08-30)
Predicting the risk of death in patients with known coronary artery disease
The extent of anatomic coronary artery disease, along with age and the presence of diabetes, is a strong predictor of subsequent death due to any cause and due to coronary artery disease (CAD). view more (2006-02-14)
Evidence found for genes that affect risk of developing Alzheimer's disease
Through one of the largest studies yet of Alzheimer's disease (AD) patients and their brothers, sisters, and children, researchers at Mayo Clinic Jacksonville have found strong evidence that genes other than the well-known susceptibility risk factor APOE4 influence who is at risk for developing the neurodegenerative disease later in life. view more (2008-01-18)
Biomarkers for identifying infant infections
Infection is the leading cause of infant deaths worldwide, and particularly a common killer of weaker, pre-term infants. Current diagnostic tests can be slow and non-specific, but researchers have now identified potential biomarkers in the blood that can rapidly identify both the onset of infection and type of microbe. view more (2008-10-15)
Insulin signaling and amphetamines
Abuse of psychostimulants such as amphetamine remains a serious public health concern. Amphetamines mediate their behavioral effects by stimulating dopaminergic signaling throughout reward circuits of the brain. view more (2007-10-16)

New technique offers relief for patients with spinal tumors
A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine. view more (2006-05-08)
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)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Saturn ring spokes may re-appear in July, says new U. of Colorado study
The unusual spokes that appear fleetingly on the rings of Saturn only to disappear for years at a time may become visible again by July, according to a new study spearheaded by the University of Colorado at Boulder. view more (2006-03-17)
Hyperviscous fluids: Better treatment for severe blood loss
Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. view more (2008-04-29)
High-dose vitamin C as a cancer therapy
Although early clinical studies conducted by Linus Pauling showed that high-dose vitamin C, given by intravenous and oral routes, may improve symptoms and prolong life in patients with terminal cancer, no benefits for cancer patients were seen when vitamin C therapy was administered orally in double-blind placebo-controlled studies at the Mayo... view more...
