UCSB researchers develop cross-protective vaccine
Doctors have always hoped that scientists might one day create a vaccination that would treat a broad spectrum of maladies. They could only imagine that there might be one vaccine that would protect against, say, 2,500 strains of Salmonella.   view more (2008-10-22)

Brave new world in life sciences
The biosciences are converging with information technology, nanotechnology, and materials science in unforeseen ways, yielding remarkable advances that have the potential to cure-or kill.   view more (2006-08-24)

Study reveals mechanism for cancer-drug resistance
Using the worm Caenorhabditis elegans, researchers at UT Southwestern Medical Center have discovered a mechanism by which cancer cells become resistant to a specific class of drugs.   view more (2006-10-10)

Slow but sure — Burned forest lands regenerate naturally
A new study of forest lands that burned in the 1990s in northern California and southwestern Oregon has concluded there is a "fair to excellent" chance that an adequate level of conifers will regenerate naturally, in sites that had no manual planting or other forest management.   view more (2007-04-04)

A single mechanism for hypertension, insulin resistance and immune suppression
Many of the 75 million Americans with essential hypertension also develop diabetes and other complications in addition to their high blood pressure, and researchers have discovered a common molecular mechanism in a strain of rat that explains why such metabolic disorders arise together in mammals.   view more (2008-06-30)

Brainstem blocks pain to protect key behaviors
Certain behaviors, such as eating, drinking and urinating, are so crucial to survival that the brains of all vertebrates contain clusters of nerve cells that can suppress pain long enough to allow the animal to eat, drink - or pee - in peace.   view more (2005-11-08)

NEW THERAPEUTIC APPROACH TO CORONARY STENTING (p 2037)
Patients given stent implantation to treat coronary heart disease could benefit from a new therapeutic approach with the platelet glycoprotein IIb/IIIa inhibitor eptifibatide, concludes research published in this week's issue of THE LANCET. The platelet glycoprotein IIb/IIIa inhibitors are potent... view more (2000-12-13)

Green manure and fodder crops accepted in Tanzanian banana cultivation
Plantains, otherwise known as cooking bananas, are an important food crop in Tanzania and require fertile soil for a good harvest. For around four centuries now, banana-growing land has been enriched by supplements of manure from cattle grazing on nearby pastures. The strongly increasing population... view more (2004-11-12)

Researchers & bakers combine to plug mineral gap in UK soil linked to fertility & cancer
A consortium of researchers, farmers and a major baker are working together to fill future supermarket shelves with loaves of bread that will arrest the plummeting levels in the UK diet of a mineral that plays a significant role in male fertility and the prevention of some cancers.   view more (2004-09-23)

Subliminal advertising leaves its mark on the brain
UCL (University College London) researchers have found the first physiological evidence that invisible subliminal images do attract the brain's attention on a subconscious level.   view more (2007-03-09)

Researchers identify genetic switch critical for cell survival in hypoxia
Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive.   view more (2008-10-17)

Tuberculosis Still a Risk for Patients Receiving HIV Drugs
People taking highly active antiretroviral therapy (HAART) for HIV infection remain susceptible to tuberculosis, though the risk is lower than for HIV-infected patients not on HAART.   view more (2005-11-14)

Wildfires result in loss of forests reserved by Northwest Forest Plan
Although the Northwest Forest Plan (NWFP) significantly reduced cutting of old-growth forests on federal land, forests in the driest regions are now at greater risk of being lost to wildfire than to logging.   view more (2008-11-07)

A spicy solution for colon cancer?
In the last few years, that tactic has proved productive for researchers investigating turmeric, a curry spice used for centuries in Indian traditional medicine.   view more (2006-09-20)

Acid suppression medication linked with increased risk of hip fracture
Use of the drugs proton pump inhibitors (PPIs) for the treatment of acid-related diseases such as gastro esophageal reflux disease (GERD) is associated with a greater risk of hip fracture.   view more (2006-12-27)

Exploiting Nature's Weapons in the Fight Against Diabetes
Scientists at the University of Ulster are harnessing molecules produced naturally in the body to tackle one of the world's major health problems - diabetes. Their novel approach involves bioengineering gut peptides - molecules produced in the human intestine and released in response to feeding -... view more (2004-03-23)

Silencing small but mighty cancer inhibitors
Researchers from Johns Hopkins and the University of Pennsylvania have uncovered another reason why one of the most commonly activated proteins in cancer is in fact so dangerous.   view more (2007-12-11)

New biomarker predicts effectiveness of breast cancer drugs
University of Cincinnati (UC) researchers have identified a new way to predict when anti-estrogen drug therapies are inappropriate for patients with hormone-dependent breast cancer.   view more (2006-12-08)

Testosterone key to disease transmission
High levels of testosterone may be a key factor in spreading disease among mice, according to biologists. The findings could help explain why males in a population are often more likely to get infected, and transmit disease.   view more (2008-08-11)

Researchers find 'secret weapon' used by SARS virus
In 2003, the highly contagious and often-deadly mystery disease now called SARS emerged explosively out of Southern China. It eventually killed an estimated 916 people in Asia, Europe, and North and South America-nearly one in ten of those it infected.   view more (2006-08-08)

190 End-Stage Renal Disease Patients Die Each Day: Epogen Usage Questioned
Seminars in Dialysis, a peer-reviewed journal published by Blackwell Publishing, is featuring the much-publicized* controversial editorial authored by Dennis Cotter in its May issue, despite outright rejection from a competitive journal, Dialysis and Transplantation. Cotter asks the important... view more (2004-06-11)

Anti-inflammatory drug's potentially deadly side effect found to be rare
Scientists have completed an extensive study of more than 3,000 patients who received a promising anti-inflammatory drug, natalizumab, that was linked to three cases of a serious brain infection in large clinical trials halted in early 2005.   view more (2006-03-02)

HIV-1's high virulence might be an accident of evolution
The virulence characteristic of HIV-1—the virus predominantly responsible for human AIDS—might amount to an accident of evolution, new evidence reveals.   view more (2006-06-16)

Parkinson's Disease Mechanism Discovered
Howard Hughes Medical Institute researchers have pinpointed defects in a critical cellular pathway that can lead to the death of dopamine-producing nerve cells and ultimately symptoms of Parkinson's disease.   view more (2006-06-23)
