Crucial advances in 'brain reading' demonstrated (December 23, 2011) -- A new study demonstrates several crucial advances in "brain reading" or "brain decoding" using computerized machine learning methods. Researchers classified data taken from people being scanned while watching videos meant to induce nicotine cravings and detected whether people were watching and resisting cravings, indulging in them, or watching videos that were unrelated to smoking or cravings. ... > full story

Multiple sclerosis linked to different area of brain (December 23, 2011) -- Radiology researchers have found evidence that multiple sclerosis affects an area of the brain that controls cognitive, sensory and motor functioning apart from the disabling damage caused by the disease's visible lesions. ... > full story

Researchers use light to measure cancer cells' response to treatment (December 23, 2011) -- Many cancer therapies target specific proteins that proliferate on the outside of some cancer cells, but the therapies are imperfect and the cancer does not always respond. Researchers have now demonstrated a new way to optically test cultured cancer cells' response to a particular cancer drug. ... > full story

New method for watching proteins fold (December 23, 2011) -- A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general. ... > full story

Myths and truths of obesity and pregnancy (December 23, 2011) -- Ironically, despite excessive caloric intake, many obese women are deficient in vitamins vital to a healthy pregnancy. This and other startling statistics abound when obesity and pregnancy collide. Together, they present a unique set of challenges that women and their doctors must tackle in order to achieve the best possible outcome for mom and baby. ... > full story

What makes anesthetics work (December 23, 2011) -- Researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study. ... > full story

How bacteria fight fluoride in toothpaste and in nature (December 23, 2011) -- Researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay. ... > full story

Balancing the womb: New research may explain premature births (December 23, 2011) -- New research may explain premature births and failed inductions of labor. The study suggests a new mechanism by which the level of myosin phosphorylation is regulated in the pregnant uterus. ... > full story

Sleep disorders common among police officers (December 23, 2011) -- A survey of police officers indicated that about 40 percent have a sleep disorder, which was associated with an increased risk of adverse health, safety and performance outcomes, according to a new study. ... > full story

Starch intake may influence risk for breast cancer recurrence, study suggests (December 23, 2011) -- Researchers have linked increased starch intake to a greater risk for breast cancer recurrence, according to new results. ... > full story

Possible cure for leukemia found in fish oil (December 23, 2011) -- A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to researchers. ... > full story

When nerve cells stop speaking: Neuroscientists decode important mechanism of nerve cell communication (December 23, 2011) -- By researching fruit flies, neuroscientists were able to gain a better understanding of a meaningful mechanism of neuronal communication. They demonstrated the importance of a specific protein for signal transmission between nerve cells. This is of high significance as certain people with autism - a functional development disturbances of the brain - suffer from genetic defects in this protein. Therefore the findings could improve the possibility of treating this disease more effectively. ... > full story
