      New Cancer Scan Promising, But Much Testing Remains

      (Newser) - A study claiming to dramatically reduce the risk of lung-cancer death is the object of intense scientific debate, Philip Boffey writes in the New York Times . Researchers screened asymptomatic smokers with spiral CT scans, which are more sensitive than the traditional chest X-ray. They estimate 92% of those found to have early-stage tumors, and get them removed, would survive the next decade. More »

      Some Docs Snub Handouts From Drug Firms

      (Newser) - Academic scientists are retreating from their traditional cushy advisory roles with drug and medical companies or doing work pro bono, the New York Times reports. Researchers offered fees for advice once didn't think twice. “People thought they were suckers if they didn’t,” one med school professor says. But now, many cite concerns over ethics or reputation as reason to give up the cash. More »

    • Eating Right Slims Risk of Strokes, Heart Attacks

      Associated Press  |  Apr 15, 08 2:59 AM CDT

      Eating Right Slims Risk of Strokes, Heart Attacks

      (Newser) - Women following a government-recommended diet to lower blood pressure significantly reduced their risk of heart attacks and strokes, AP reports. Those following a diet high in fruit, vegetables and grains were 24% less likely to have a heart attack and 18% less likely to have a stroke than women eating typical American diets, according to the study in the Archives of Internal Medicine.

      Depression Linked to Alzheimer's

      (Newser) - Nearly 50% of Alzheimer's patients also suffer from depression, and new studies suggest the depression came first, WebMD reports. Researchers found that elderly people with a history of depression were much more likely to develop dementia. The findings give greater urgency to early treatment for depression, experts warn.

    • For Infections, Try Gator-cillin

      For Infections, Try Gator-cillin

      (Newser) - Scientists are trying to harness the power of alligator blood to fight disease, bacterial infections, and even HIV, Cox News reports. Proteins in the reptiles' blood have antibiotic properties thanks to the animals' long evolution and frequent exposure to bacteria; their exceptionally effective immune systems can fight off invaders without previous exposure. "It's pretty exciting," says one gator researcher. More »

      Parkinson's Spreads to Transplanted Cells

      (Newser) - Transplanting healthy cells into the brains of people with Parkinson's alleviates symptoms, but sufferers showed signs of deterioration as the disease spread to the grafted cells, according to two studies in the journal Nature Medicine . Scientists in Sweden and Chicago discovered similar results in patients who received cell transplants up to 16 years ago. More »

      Water-Guzzling Benefits Don't Wash

      (Newser) - Kidney experts looking into the alleged health benefits of drinking lots of water have found the evidence to be far from watertight, Reuters reports. Claims that increased water intake improves skin tone, flushes toxins from the body, reduces appetite, and prevents headaches have little solid research behind them, according to a study to be published in the Journal of American Phrenology .

    • A Coffee a Day May Keep Dementia Away: Study

      BBC  |  Apr 3, 08 4:52 AM CDT

      A Coffee a Day May Keep Dementia Away: Study

      (Newser) - A daily fix of caffeine helps shield the brain from the damaging effects of cholesterol, which is apparently the way coffee helps reduce the risk of dementia, new research suggests. The "blood-brain barrier" protects the brain from toxins in the bloodstream, but scientists have discovered that cholesterol makes it leaky. The strength of the barrier was boosted in rabbits given the caffeine equivalent of a daily cup of joe, reports the BBC. More »

    • Diabetes Drug Slows Artery Clogging

      Diabetes Drug Slows Artery Clogging

      (Newser) - A drug used to lower blood sugar in diabetics significantly decreases the clogging of arteries, the Cleveland Plain Dealer reports. Tests on diabetic patients found that Actos, a new-generation drug that lowers insulin resistance, aided arteries more than a drug that boosted insulin production. Heart disease kills 75% of diabetics and doctors are working to find ways to treat both blood sugar and heart disease. More »

      Risk Rises if 2 Parents Have Alzheimer's

      (Newser) - People whose mom and dad have Alzheimer's run a much higher risk of getting the disease, a new study finds. Researchers at the University of Washington in Seattle looked at 111 families in which both parents have Alzheimer's, and found that 42% of those aged 70 and up got the disease. Only one in 10 develop it in the general population, Reuters reports. More »

      Substitutes Not All Sweetness and Light

      (Newser) - Cutting back on sugary calories could make you gain weight instead of lose it, a study suggests. Scientists at Purdue University compared rats fed either zero-calorie saccharin or sugar, and found that those on artificial sweetener gained more weight—mostly in fat, Time reports. Animals appear conditioned to respond to sugar by eating less; when they don't taste it, they eat more. More »

      Pill Guards Against Ovarian Cancer: Study

      (Newser) - Oral contraceptives "confer powerful and long-lasting protection" against ovarian cancer, a cancer that often proves deadly because it's so difficult to diagnose early, a new study has found. The effect is so strong that women who take the pill for 10 years will enjoy significant protection against ovarian cancer even 30 years later, the Canadian Press reports. More »

    • Study Finds Mutated Genes Raise Autism Risk

      Study Finds Mutated Genes Raise Autism Risk

      (Newser) - Researchers studying the DNA of autistic children have discovered a pair of genetic mutations that raise the risk of developing autism as high as a hundredfold, USA Today reports. The defects in chromosome 16 occur in just 1% of autistic kids, but that figure represents some 10,000 children. A test has been developed to identify the mutations, which may be "the tip of the iceberg" of genetic aberrations linked to
