Chemical Cudgel in Plants
Defense mechanisms of single-celled algae Plankton are at the bottom of the food chain in all natural bodies of water and are thus correspondingly important for their ecological balance. In the cycle of eating and being eaten it isn't only fish and whales that prey on these tiny animals and plants - they also eat each other. For example, a variety... view more... (2000-11-29)
HIV isolate from Kenya provides clues for vaccine design
Two simple changes in its outer envelope protein could render the AIDS virus vulnerable to attack by the immune system, according to research from Kenya and the Fred Hutchinson Cancer Research Center published in PLoS Medicine. view more (2008-01-03)
Study shows more genes are controlled by biological clocks
The tick-tock of your biological clock may have just gotten a little louder. Researchers at the University of Georgia report that the number of genes under control of in living things than suspected only a few years ago. view more (2008-08-29)
Yin and yang -- Balance could play key role in progression of Alzheimer's disease
Researchers at Rensselaer Polytechnic Institute are challenging current thinking on the causes and prevention of Alzheimer's disease, offering a new hypothesis that could be the key to preventing this form of dementia. view more (2007-05-30)
Purdue-IU researchers explore new method for early disease diagnosis
Purdue University researchers worked with the Indiana University School of Medicine to establish a technique that provides a new approach for detecting a number of genetic disorders found in infants and young children. view more (2007-07-19)
Amino acid may help treat patients with hair-pulling condition
The amino acid N-acetylcysteine appears to reduce symptoms of compulsive hair-pulling in patients with a condition known as trichotillomania. view more (2009-07-07)
Low-carbohydrate diet burns more excess liver fat than low-calorie diet, study finds
People on low-carbohydrate diets are more dependent on the oxidation of fat in the liver for energy than those on a low-calorie diet, researchers at UT Southwestern Medical Center have found in a small clinical study. view more (2009-01-21)
New University of Bath arrival could help banish painful injections
One of the world's leading experts on a new technique that could make painful injections a thing of the past, arrives at the University of Bath as the new Professor of Pharmaceutical Sciences this month. Professor Richard Guy is joining the Department of Pharmacy and Pharmacology after eight years at the University of Geneva in Switzerland. He is... view more... (2004-08-16)
A salty tale: New bacterial genome sequenced from ancient salterns
Tourists in Spain often stop to ogle the country's many saltwater lagoons, used to produce salt since Roman times. Scientists, too, admire these saltern crystallizers-and even more so, the microbes that manage to survive in such briny environs. view more (2005-12-06)
Researchers Identify Biofilms That Cause Infection
Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their... view more...

Higher Trans Fat Levels in Blood Associated With Elevated Risk of Heart Disease
High consumption of trans fat, found mainly in partially hydrogenated vegetable oils and widely used by the food industry, has been linked to an increased risk of coronary heart disease (CHD). view more (2007-03-28)
New techniques in plant chloroplast division hold hope for agriculture
Ground-breaking research at the University of Leicester into the division of chloroplasts holds out hope of a safer way of genetically modifying crops, with implications for agriculture particularly in the developing world. Using three plant types - Arabidopsis, tomato and rice - Dr Simon Geir M'¸ller has been working with colleagues in the... view more... (2003-01-20)
Protein translation in sperm
A new paper in the February 15th issue of Genes & Development lends novel insight into the cellular changes that occur in sperm while they reside in the female reproductive tract. view more (2006-02-15)
Beyond a 'speed limit' on mutations, species risk extinction
Harvard University scientists have identified a virtual "speed limit" on the rate of molecular evolution in organisms, and the magic number appears to be 6 mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability. view more (2007-10-02)
Therapeutic peptide frees the protein p73 to kill tumor cells
The protein p53 suppresses tumor development by potently inducing tumor cell death, making it an obvious target for anticancer therapeutics. view more (2007-03-09)
The Metabolic Syndrome - Are You Aware Of The Risk?
It has been estimated that the prevalence of adult obesity across the EU ranges from 10-25% and may be as high as 30%. Many more people are overweight, and the prevalence continues to rise. This worrying trend, sometimes referred to as an 'epidemic', is now well recognized, but the extent to which obesity adversely affects health doesn't make the... view more... (2005-05-20)
Transplanting human gut bugs into mice helps understanding of metabolic system
Bugs found in the guts of humans, which play an important part in people's metabolic makeup, have been transplanted into mice to further understanding of the human and animal metabolic system. view more (2007-05-22)
Avoiding house dust mites and changing diet proves ineffective
New research shows avoiding house dust mite allergens from birth does not prevent the onset of asthma, eczema or atopy in high-risk children. view more (2006-06-29)
Protein sensor for fatty acid buildup in mitochondria
Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks down these fatty acids, according to investigators at St. Jude Children's Research Hospital. view more (2007-02-15)
Omega-3s boost grey matter, findings may explain why omega-3s seem to improve mood
Omega-3 fatty acids, found in fatty fish like salmon, are associated with increased grey matter volume in areas of the brain commonly linked to mood and behavior according to a University of Pittsburgh study. view more (2007-03-07)
