Cancer-metabolism link runs deep in humans, novel network algorithm suggests (July 23, 2010) -- Eighty years ago, the medical establishment believed cancer was caused by a dysfunction of metabolism, but the idea went out of vogue. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. ... > full story
Medicine from moss: Bioreactor technique may offer hope to people with age-related blindness (July 23, 2010) -- Biologists in Germany have used a moss bioreactor to produce a human protein, the absence of which leads to age-related blindness in 50 million people. ... > full story
Can I buy you a drink? Genetics may determine sensitivity to other people's drinking behavior (July 23, 2010) -- Your friend walks into a bar to meet you for happy hour. He sidles up to the bar and orders a drink -- does that make you more likely to get a drink yourself? According to new findings, genetics may determine the extent to which you are influenced by social drinking cues -- signals such as advertisements, drinks placed on a bar, and seeing other people around you drinking. ... > full story

Identification of a gene essential to newborn babies' first breath (July 23, 2010) -- How do mammals prepare themselves in utero for a radical modification to their respiration at the time of birth, when they move abruptly from an aquatic medium to air? Researchers have identified a gene in the mouse that is essential to respiration and consequently to survival at birth. This work opens the way to better understanding respiratory disorders in humans, which can range from sleep apnea to sudden infant death syndrome. ... > full story

However, psychiatry is one area of medicine where there are few diagnostic blood tests. Dutch researchers evaluated blood gene expression profiles in healthy individuals and patients diagnosed with major depressive disorder, or MDD. They identified a set of seven genes in whole blood that was able to distinguish un-medicated MDD patients from healthy controls. ... > full story
