Does fluoride really fight cavities by 'the skin of the teeth?' (December 18, 2010) -- In a study that the authors describe as lending credence to the idiom, "by the skin of your teeth," scientists are reporting that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. It raises questions about how this renowned cavity-fighter really works and could lead to better ways of protecting teeth from decay, the scientists suggest. ... > full story
Protein disables p53, drives breast cells toward cancer transition (December 18, 2010) -- The recently identified TRIM24 protein plays an active role in pushing normal breast cells into rapid cell proliferation and, potentially, into breast cancer. ... > full story
Drinking alcohol during a rich meal slows down digestion, but doesn't increase indigestion, study finds (December 18, 2010) -- People can be reassured that while alcohol may slow down digestion after a rich calorific meal, enjoyed by many during the Christmas season, it will not cause indigestion symptoms such as heartburn, belching and bloating, finds new research. ... > full story
Prions mutate and adapt to host environment (December 18, 2010) -- Scientists have shown that prions, bits of infectious protein that can cause fatal neurodegenerative disease such as bovine spongiform encephalopathy (BSE) or "mad cow disease," have the ability to adapt to survive in a new host environment. ... > full story
Major shift in understanding how eczema develops (December 18, 2010) -- In eczema patients the skin barrier is leaky, allowing pollen, mold, pet dander and other irritants to be sensed by the skin and subsequently wreak havoc on the immune system. While the upper-most layer of the skin has been pinned as the culprit in previous research, a new study found that a second skin barrier structure is also faulty in eczema patients and likely plays a role in the development of the disease. ... > full story
Researchers develop mouse model to help find how a gene mutation leads to autism (December 18, 2010) -- Researchers have found that when one copy of the SHANK3 gene in mice is missing, nerve cells do not effectively communicate and do not show cellular properties associated with normal learning. This discovery may explain how mutations affecting SHANK3 may lead to autism spectrum disorders. ... > full story
Circadian rhythm: Clock-controlled genes discovered in C. elegans (December 18, 2010) -- It's just a worm, a tiny soil-dwelling nematode worm -- but the implications are big for biomedicine and circadian biology as shown in a recent study. Researchers have now discovered clock-controlled genes in C. elegans. ... > full story
Emotional intelligence peaks as we enter our 60s, research suggests (December 18, 2010) -- Older people have a hard time keeping a lid on their feelings, especially when viewing heartbreaking or disgusting scenes in movies and reality shows, psychologists have found. But they're better than their younger counterparts at seeing the positive side of a stressful situation and empathizing with the less fortunate, according to new research. ... > full story
Where unconscious memories form (December 17, 2010) -- A small area deep in the brain called the perirhinal cortex is critical for forming unconscious conceptual memories, researchers have found. ... > full story
Novel drug offers hope for early intervention in cystic fibrosis patients (December 17, 2010) -- Cystic fibrosis (CF) patients with normal to mildly impaired lung function may benefit from a new investigational drug designed to help prevent formation of the sticky mucus that is a hallmark of the disease, according to researchers involved in a phase 3 clinical trial of the drug. Called denufosol, the investigational medication can be given early in the CF disease process, and may help delay the progression of lung disease in these patients, the researchers found. ... > full story
Ion channel responsible for pain identified (December 17, 2010) -- Neuroscience researchers conducting basic research on ion channels have demonstrated a process that could have a profound therapeutic impact on pain. ... > full story
Asthma disproportionately affects low-income populations (December 17, 2010) -- Almost 5 million Californians have been diagnosed with asthma, and those living in poverty suffer more severe consequences than those in higher income brackets, according to a new report. Low-income Californians with asthma experience more frequent symptoms, end up in the emergency room or hospital more often, and miss more days of work and school. The study calculates prevalence among adults and children in California counties. ... > full story
