- Cancer Vaccine Shows Promise
  
  newser | Reuters | Jun 24, 08 5:11 PM CDT
  
  Encouraging results in experiments on mice are raising hopes of an effective colon cancer vaccine, Reuters reports. Capitalizing on the fact that the intestines have their own immune system, researchers isolated a protein that occurs only in the gut to create a vaccine. In treated mice, an average of three tumors appeared in the lungs or liver. In unvaccinated mice, the number was 30. More »

- New Trust Drug: Good for Shyness, Bad for Investing
  
  newser | BBC | May 22, 08 9:46 AM CDT
  
  Scientists have created a nasal spray that makes its users more trusting, the BBC reports. Made up mostly of oxytocin, alternatively nicknamed the “love hormone” or “cuddle chemical,” the spray decreases social fears by lowering activity in the amygdala. That should be great news for social phobics; just don’t use it when you’re, say, making investment decisions. More »

  newser | Seattle Post-Intelligencer | May 18, 08 12:50 PM CDT
  
  Doggy wants a bone, and he deserves it too. Canines will soon be lining up at Washington State University for bone marrow transplants, enjoying a little payback after pooches made the procedure possible in people, the Seattle Post-Intelligencer reports. But the cancer treatment won't come cheap: WSU will treat man’s best friend for about $15,000 to $20,000 each. More »

- Vitamin D May Curb Breast Cancer: Study
  
  newser | Globe and Mail | May 16, 08 7:28 AM CDT
  
  Vitamin D deficiency has been linked to the spread of breast cancer tumors to other parts of the body, reports the Toronto Globe and Mail. Women diagnosed with breast cancer were twice as likely to see it spread and 73% more likely to die early if they had low levels of the vitamin, a new study says. More »

- Robot Worms Offer Cancer Hope
  
  newser | ABC News | May 13, 08 2:31 PM CDT
  
  Little mechanical “worms” offer the latest hope for early detection—and eradication—of cancer. Researchers have created tiny machines that travel through the body, find tumors that are too small to see in normal scans, and then deliver drugs to kill them. The method has worked to spot tumors in mice, but it’s still years from human use, ABC reports. More »

- Smaller Babies Become Hostile Adults: Study
  
  newser | Reuters | May 13, 08 6:16 AM CDT
  
  New research has linked low birth weight and slow growth in childhood to increased levels of hostility in adults, Reuters reports. Researchers also discovered that the higher levels of aggression were linked to health trouble, including coronary problems, type 2 diabetes and earlier death. The levels of hostility appeared unconnected to any other factors like gender, number of siblings or educational level. More »

- Pot Linked to Heart Attack Risk
  
  newser | Reuters | May 13, 08 3:07 AM CDT
  
  Heavy users of marijuana have elevated levels of a protein that can raise the risk of heart disease, stroke and heart attacks, according to US government researchers. The drug apparently causes the liver to overproduce the protein, raising serious health issues for long-term smokers, researchers warned. The survey studied people who smoked 78 to 350 joints a week, Reuters reports. More »

- What We Can Learn From Being Dog-Tired
  
  newser | New York Times | May 6, 08 2:33 PM CDT
  
  Alaskan sled dogs racing for days on end don’t get tired out the way a human runner would, the New York Times reports, and researchers eager to imitate this fatigue resistance in people—particularly soldiers—say it’s because they’re somehow able to change their metabolism. “Suddenly they throw a switch—we don’t know what it is yet,” one researcher said.

- Science Could Crack Peanut Allergy: Expert
  
  newser | Reuters | May 3, 08 6:03 AM CDT
  
  Scientists are working to help those with peanut allergies and may even replace nuts with a tasty, genetically modified snack, one expert says. "There are multiple types of studies that are ongoing now," said Dr. Wesley Burks of Duke University. "I think there's some type of immunotherapy that will be available in five years.” And the need for peanut allergy relief is rising, Reuters reports. More »

  A UK plastic surgeon repudiated claims by an American company that a powder made from a pig’s bladder spurred regrowth of a man’s severed fingertip, the Guardian reports. Stories circulated this week of Lee Spievack’s “miraculous” recovery thanks to what he called “pixie dust,” but Simon Kay, professor of hand surgery at the University of Leeds, said the reports were “junk science.” More »

- Despite Danger, FDA Sanctioned Artificial Blood Studies
  
  newser | Washington Post | Apr 28, 08 1:50 PM CDT
  
  The Food and Drug Administration repeatedly approved experiments using artificial blood despite data showing the products to be dangerous, the Washington Post reports. Investigators from the National Institutes of Health found heart attack risk tripled and death increased by 30% for subjects in 16 studies testing five kinds of artificial blood, which, it is hoped, will ultimately provide alternative transfusions.

- New Cancer Scan Promising, But Much Testing Remains
  
  newser | New York Times | Apr 24, 08 5:40 PM CDT
  
  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 »

  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 »

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

  newser | Cox Newspapers | Apr 7, 08 3:28 PM CDT
  
  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 »

  newser | Reuters | Apr 3, 08 12:22 PM CDT
  
  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 .
