Torrefacto-roasted coffee has higher antioxidant properties than natural roast, according to a young biologist. She has emphasized in her study that the addition of sugar during the roasting process increases the development of compounds with high antioxidant activity. Coffee has an antioxidant capacity which is ten times higher than other drinks, such as red wine and tea.

Animal models have been invaluable in understanding how gene mutations physically affect a complex organism. However, as vividly illustrated in a new research study examining mice with a metabolic disease, the same mutation in the same species can produce wildly variable results.

Scientists have discovered that the roundworm C. elegans constructs the protective tips of its chromosomes -- known as telomeres -- with a little more panache than do mammals, a finding that could deepen our understanding of the interrelationship of aging and cancer.

Researchers have found that lipid molecules in cell membranes participate in mammals' reactions to allergens in a living cell. The finding will help scientists better understand how allergy symptoms are triggered, and could contribute to the creation of improved drugs to treat them.

Strawberries, grapes, blueberries and some familiar seasonings like rosemary contain compounds that can--in test tubes--kill cells of a childhood cancer. Molecular biologists are working to understand exactly how the powerful plant chemicals fight the disease known as acute lymphoblastic leukemia. Investigations provide some new clues about how phytochemicals attack cancer cells. Phytochemicals interfere with the orderly operations of mitochondria, the miniature energy-producing power plants inside cells.

Previous studies have pointed out the benefits of moderate alcohol consumption as a factor in lowering cardiovascular risk. Researchers have now found that middle-aged nondrinkers who began consuming moderate amounts of alcohol saw an immediate benefit of lower cardiac disease morbidity with no change in mortality after four years.

Breakfast of champions? That would be a soy protein-packed, low-fat, high-fiber cereal that meets the requirements for three different FDA health claims and leaves you feeling full so you won't be tempted to eat again until lunch. Scientist have cooked up a "recipe" for just such a cereal, one that's passed the taste test of her sensory panel.

A brain network linked to introspective tasks -- such as forming the self-image or understanding the motivations of others -- is less intricate and well-connected in children, scientists have learned. They also showed that the network establishes firmer connections between various brain regions as an individual matures. The scientists are working to establish a picture of how these connections and other brain networks normally develop and interact.

Researchers seek to gain edge in war against ancient foe, TB. They have isolated the molecular 'weapons' of the bacterium and are now assessing ways to make the bacterium impotent. They are focusing on two proteins in the TB bacterium which, it is thought, allows it to thrive in white blood cells.

Smoking may exacerbate the increased risk of a blood vessel bursting inside the brain (intracerebral stroke) already faced by people with high blood pressure, according to a new study in Stroke: Journal of the American Heart Association. For every 10 millimeters of mercury (mm Hg) increase in systolic blood pressure (the top number in a reading), smokers face an additional 15 percentage point increase in risk of hemorrhagic stroke (bleeding in the brain), compared with nonsmokers.
