Mad Cow Disease Also Caused By Genetic Mutation (September 13, 2008) -- New findings about the causes of mad cow disease show that sometimes it may be genetic. Until several years ago, it was thought that the cattle prion disease bovine spongiform encephalopathy -- also called BSE or mad cow disease -- was a foodborne disease. ... > full story
Infidelity Dissected: New Research On Why People Cheat (September 13, 2008) -- The probability of someone cheating during the course of a relationship varies between 40 and 76 percent. "It's very high," say researchers. ... > full story
Some Bladder Problems Are Provoked By Colon (September 13, 2008) -- For up to a million women, enjoying a piece of pepperoni pizza has painful consequences. They have a chronic bladder condition that causes pelvic pain. Spicy food, as well as citrus and caffeine, can intensify the pain, which is so intense some women inject lidocaine into their bladders. Researchers previously thought chemicals from the food irritated the bladder. A surprising discovery now reveals the symptoms actually are being provoked by the colon. The discovery opens up new treatment possibilities. ... > full story
'Dodgy Dossier' Partly To Blame For Failure Of War Against Malaria In The Tropics (September 13, 2008) -- The war against malaria in tropical countries was fought and lost in the 20th century on the basis of faulty intelligence, a 'dodgy dossier' which argued that the same methods used to tackle the disease in temperate countries would also work in the tropics. ... > full story
DNA 'Tattoos' Link Adult, Daughter Stem Cells In Planarians (September 13, 2008) -- Using the molecular equivalent of a tattoo on DNA that adult stem cells pass to their "daughter" cells in combination with gene expression profiles, researchers have identified two early steps in adult stem cell differentiation -- the process that determines whether cells will form muscle, neurons, skin, etc., in people and animals. ... > full story
Key Enzyme For Regulating Heart Attack Damage Found, Scientists Report (September 13, 2008) -- Marauding molecules cause the tissue damage that underlies heart attacks, sunburn, Alzheimer's and hangovers. But scientists say they may have found ways to combat the carnage after discovering an important cog in the body's molecular detoxification machinery. ... > full story
Tracking Down The Menace In Mexico City Smog (September 13, 2008) -- Chemical scientists have shown that, bad as the traffic is, the most harmful air pollution in Mexico City may not come from burning fossil fuels. Instead the culprit may be garbage incineration. ... > full story
New Marker For Raised Intracranial Pressure (September 13, 2008) -- Magnetic resonance imaging measurements of the thickness of the optic nerve sheath are a good marker for raised intracranial pressure. New research shows that a retro-bulbar optic nerve sheath diameter above 5.82mm predicts raised ICP in 90 percent of cases. ... > full story
New Method For Creating Inducible Stem Cells Is Remarkably Efficient (September 13, 2008) -- Some of the most challenging obstacles limiting the reprogramming of mature human cells into stem cells may not seem quite as daunting in the near future. Two independent research papers describe new tools that provide invaluable platforms for elucidating the molecular, genetic, and biochemical mechanisms associated with reprogramming. ... > full story
Amount Of Work For Medical Residents -- Not Just Hours -- Need Review, Study Finds (September 13, 2008) -- The first objective study on the effect that on-call workloads have on the quality of the education medical residents receive found that the complexity of care patients require has just as much impact on residents' training as the number of hours they work. ... > full story
Untapped Potential Of Antidepressants For Cancer (September 13, 2008) -- A comprehensive review of current scientific literature has suggested that antidepressants can help the human body fight cancer by boosting its own immune response, amongst other mechanisms. ... > full story
Early Stage Colon Cancer Characterized By Inactivation Of Gatekeeper Gene (September 13, 2008) -- The absence or inactivation of the RUNX3 gatekeeper gene paves the way for the growth and development of colon cancer, Singapore scientists report in the September issue of the journal Cancer Cell. Previous studies have shown that RUNX3 plays a role in gastric, breast, lung and bladder cancers. ... > full story
