Reactive oxygen in fruit flies acts as a cell signalling mechanism for immune response
For years, health conscious people have been taking antioxidants to reduce the levels of reactive oxygen in their blood and prevent the DNA damage done by free radicals, which are the result of oxidative stress. But could excessive use of antioxidants deplete our immune systems? view more (2009-09-24)
Evolutionary conservation of a mechanism of longevity from worms to mammals
Though the study of aging in the nematode model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. view more (2005-10-05)
Antioxidants offer pain relief in patients with chronic pancreatitis
Antioxidant supplementation was found to be effective in relieving pain and reducing levels of oxidative stress in patients with chronic pancreatitis (CP), reports a new study in Gastroenterology. view more (2009-01-05)
Researchers discover that growing up too fast may mean dying young in honey bees
Reactive oxygen species (ROS) occur as a by-product of aerobic metabolism and impair cellular function by damaging proteins, nucleotides and lipids. view more (2008-09-25)
Osteoarthritis may be sign of faster 'biological ageing'
Osteoarthritis, the degenerative inflammatory bone disease, may be a sign of faster "biological ageing," suggests research published ahead of print in the Annals of the Rheumatic Diseases. view more (2006-10-02)
Reduced insulin in the brain triggers Alzheimer's degeneration
By depleting insulin and its related proteins in the brain, researchers at Rhode Island Hospital and Brown Medical School have replicated the progression of Alzheimer's disease - including plaque deposits, neurofibrillary tangles, impaired cognitive functioning, cell loss and overall brain deterioration - in an experimental animal model. view more (2006-03-23)
Prevent prostate cancer with antioxidants? Gene pathway may reveal more clues
Scientists from Maryland and New Jersey have identified a molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage. The pathway, which is also involved in human prostate cancer, may help determine how and whether antioxidants, such as certain vitamins or their products that reverse the damage, can prevent... view more...

Gene may 'bypass' disease-linked mitochondrial defects, fly study suggests
By lending them a gene normally reserved for other classes of animals, researchers have shown they can rescue flies from their Parkinson's-like symptoms, including movement defects and excess free radicals produced in power-generating cellular components called mitochondria. view more (2009-05-06)
Diabetes drug shows promise for preventing brain injury from radiation therapy
Researchers at Wake Forest University School of Medicine are the first to report that in animal studies, a common diabetes drug prevents the memory and learning problems that cancer patients often experience after whole-brain radiation treatments. view more (2007-01-11)
Study links faulty DNA repair to Huntington's disease onset
Huntington's disease, an inherited neurodegenerative disorder that affects roughly 30,000 Americans, is incurable and fatal. view more (2007-04-23)
Phytochemicals in plant-based foods could help battle obesity, disease
The cheeseburger and French fries might look tempting, but eating a serving of broccoli or leafy greens first could help people battle metabolic processes that lead to obesity and heart disease, a new University of Florida study shows. view more (2009-10-22)
Blood urate levels associated with the progression of Parkinson's disease
Higher blood levels of the compound urate, a salt derived from uric acid that is associated with gout, may be associated with a slower progression of Parkinson's disease. view more (2008-04-15)
Everybody dance: The energy you use won't shorten your life
The theory that animals die when they've expended their lifetime allotment of energy may be reaching the end of its own life, according to a study presented at The American Physiological Society conference, Comparative Physiology 2006. view more (2006-10-09)
Herbal extract found to increase lifespan
The herbal extract of a yellow-flowered mountain plant indigenous to the Arctic regions of Europe and Asia increased the lifespan of fruit fly populations, according to a University of California, Irvine study view more (2007-12-06)
Argonne scientists discover new platinum catalysts for the dehydrogenation of propane
The process to turn propane into industrially necessary propylene has been expensive and environmentally unfriendly. That was until scientists at U.S. Department of Energy's Argonne National Laboratory devised a greener way to take this important step in chemical catalysis. view more (2009-03-16)
New strategies against bird flu
The Spanish flu outbreak of 1918 killed between 30 and 50 million people. In the infected patients, the ultimate cause of death was acute respiratory distress syndrome (ARDS). view more (2008-04-18)
New study suggests Concord grape juice may provide protection against breast cancer
Every three minutes, a woman in the United States is diagnosed with breast cancer . While factors like age and heredity contribute significantly to a woman's likelihood of contracting this disease, lifestyle and nutrition choices may also play a role. view more (2007-08-10)
