Trojan horse for ovarian cancer -- nanoparticles turn immune system soldiers against tumor cells
In a feat of trickery, Dartmouth Medical School immunologists have devised a Trojan horse to help overcome ovarian cancer, unleashing a surprise killer in the surroundings of a hard-to-treat tumor. view more (2009-07-16)
Electron self-injection into an evolving plasma bubble
Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. view more (2009-11-03)
Electrical circuit runs entirely off power in trees
You've heard about flower power. What about tree power? It turns out that it's there, in small but measurable quantities. There's enough power in trees for University of Washington researchers to run an electronic circuit. view more (2009-09-09)
Laser scientists take step towards making fusion energy a reality
Scientists from the UK and Japan may have taken us one step further to the reality of fusion energy with a new answer to an old problem. Research by Dr Ryosuke Kodama and his colleagues at Osaka University, Japan and the UK team published in Nature on Thursday 23 August details a new technique for using lasers to start the fusion reaction. The... view more... (2001-08-20)
Treating obstructive sleep apnea, preventing heart attacks and strokes
Researchers in Brazil have found that treating patients who suffer from obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) dramatically reduces early indications of atherosclerosis in just months, linking OSA directly to the hardening or narrowing of the arteries. Until now, no study has demonstrated such a direct... view more... (2007-09-28)
First few seconds of earthquake rupture provides data for distant shake warnings
A University of California, Berkeley, seismologist has discovered a way to provide seconds to tens of seconds of advance warning about impending ground shaking from an earthquake. view more (2005-11-10)
Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system. view more (2008-07-07)
Progesterone therapy and preterm birth: More evidence helps identify women who can benefit
Two major studies published today in The New England Journal of Medicine can help doctors better identify pregnant women at risk for preterm delivery who can benefit from progesterone treatment, the March of Dimes Foundation said today. view more (2007-08-02)
Two-fold higher mortality from cardiovascular disease in older people with diabetes
Diabetes is on the rise, likely to affect twice as many people worldwide in 2030 as today, and a serious global health problem, because, despite available treatments, most people with diabetes develop serious long-term health problems. view more (2006-10-17)
Music calms the fevered brow
Music is not just the food of love - it may also be a pain killer and lessen anxiety. New research by psychologists has found that that people listening to music may feel less pain than those who are not and that music can relieve the symptoms of anxiety for people recovering from surgery. view more (2005-03-21)
Wistar scientists find key to keeping killer T cells in prime shape for fighting infection, cancer
Like tuning a violin to produce strong, elegant notes, researchers at The Wistar Institute have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb infection- and disease-fighting condition. view more (2008-12-01)
Nano technique allows precise injection of living cells
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells. view more (2007-06-18)
First evidence that weed killers improve nutritional value of a key food crop
Scientists are reporting for the first time that the use of weed killers in farmers' fields boosts the nutritional value of an important food a crop. view more (2009-07-09)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
Scripps research scientists enhance immune system attacks on cancer
In an Early Edition issue of the Proceedings of the National Academy of Sciences (PNAS) published online on October 20, 2008, the scientists describe how they used multiple tactics to rev up both innate and adaptive immunity to enhance the body's ability to fight cancer. view more (2008-10-22)
Combined effect of proteins saves lives in cases of pneumonia
An effective host defence to the most prevalent form of pneumonia is only obtained if two proteins combine their forces. Dutch researcher Anita Rijneveld made this discovery during her PhD research at the Academic Medical Centre, University of Amsterdam. Using mice infected with the bacterium Streptococcus pneumoniae (the bacterium which causes... view more... (2003-05-16)
Aggie physicists unite with Ivy League to develop anthrax detection method
Texas A&M University and Princeton University physicists have joined forces to perfect a powerful new weapon in the war on terrorism - a laser technique to identify deadly anthrax spores. Their results are published in the prestigious journal Science, due to hit newsstands tomorrow. view more (2007-04-13)
Quantum decoys foil code-breaking attempts
Computer code-makers may soon get the upper hand on code-breakers thanks to a new quantum cryptography method designed at the University of Toronto. Quantum cryptography uses particles of light to share secret encryption keys relayed through fibre-optic communications. view more (2005-07-19)
Senescence in liver cells is found by CSHL scientists to help limit acute tissue damage
Although post-reproductive life in humans is often associated with decline and a loss of powers, an analogous state in certain cells -- called senescence -- is proving to be one of ironic potency. Scientists at Cold Spring Harbor Laboratory (CSHL) today reported that a particular class of senescent liver cells orchestrates a sequence of events in... view more... (2008-08-22)
Study unmasks how ovarian tumors evade immune system
Scientists at Johns Hopkins have determined how the characteristic shedding of fatty substances, or lipids, by ovarian tumors allows the cancer to evade the body's immune system, leaving the disease to spread unchecked view more (2008-12-01)
