Could new drug cure nearly any viral infection? Technology shows promise against common cold, influenza and other ailments, researchers say (August 26, 2011) -- Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection. ... > full story

T-cell discovery holds promise for organ transplant and immunodeficiency treatment (August 26, 2011) -- Researchers have identified the calcium channel responsible for the activation of T-cells, one of the key elements of the immune system. ... > full story

Omega-3s reduce stroke severity, study suggests (August 26, 2011) -- A diet rich in omega-3s reduces the severity of brain damage after a stroke, according to a new study. Researches have shown that the extent of brain damage following a stroke was reduced by 25 percent in mice that consumed DHA type omega-3s daily. ... > full story

Life expectancy success story (August 26, 2011) -- Increases in life expectancy, due to better quality of life and better health care, can be patchy, with the gap between rich and poor getting bigger as time goes on. However, a new report finds that the life expectancy for people living in deprived areas in Campinas, Brazil, is catching up, rising at three times the rate of people living in more affluent areas. ... > full story

Uncovering the spread of deadly cancer: New imaging device enables scientists to see tumor cells traveling in the brain (August 26, 2011) -- For the first time, scientists can see pathways to stop a deadly brain cancer in its tracks. Researchers have imaged individual cancer cells and the routes they travel as the tumor spreads. ... > full story

Breakthrough in genetics of fibroids (August 26, 2011) -- Uterine leiomyomas, also called fibroids, cause a very significant burden to women's health. Researchers have set out to study the genetic structure of fibroids by determining the sequence of all the human genes, in a series of 18 tumors. The study revealed very specific mutations in a gene called MED12, in as many of 70 percent of the studied tumors. ... > full story

New score can tell doctors how long cancer patients have left to live (August 26, 2011) -- A new scoring system can more reliably predict whether patients with advanced cancer are likely to survive for "days", "weeks" or "months", a new study finds. ... > full story

Protein linked to Parkinson's disease may regulate fat metabolism (August 26, 2011) -- Researchers have found that Parkin, an important protein linked with some cases of early-onset Parkinson's disease, regulates how cells in our bodies take up and process dietary fats. ... > full story

Mathematical model predicts weight with varying diet, exercise changes; Findings challenge one-size-fits-all weight assumptions (August 26, 2011) -- Researchers have created a mathematical model -- and an accompanying online weight simulation tool -- of what happens when people of varying weights, diets and exercise habits try to change their weight. The findings challenge the commonly held belief that eating 3,500 fewer calories -- or burning them off exercising -- will always result in a pound of weight loss. ... > full story

Heat in chili peppers can ease sinus problems, research shows (August 26, 2011) -- Hot chili peppers are known to make people "tear up," but a new study found that a nasal spray containing an ingredient derived from hot chili peppers may help people "clear up" certain types of sinus inflammation. ... > full story

What determines a company's performance? Shape of the CEO's face! (August 26, 2011) -- Believe it or not, one thing that predicts how well a CEO's company performs is the width of the CEO's face. CEOs with wider faces have better-performing companies than CEOs with long faces. ... > full story

Natural Alzheimer's-fighting compound created inexpensively in lab (August 26, 2011) -- Scientists have developed the first practical method to create a compound called huperzine A in the lab. The compound, which occurs naturally in a species of moss found in China, is an enzyme inhibitor that has been used to treat Alzheimer's disease in China since the late 1990s and is sold in the US as a dietary supplement to help maintain memory. ... > full story
