Discovery could lead to breakthrough for non-small cell lung cancer (December 3, 2010) -- A professor of biochemistry and molecular biology has discovered a previously unknown mechanism in non-small cell lung cancer cells that contributes to their ability to maintain and grow tumors. ... > full story
The gene-environment enigma (December 3, 2010) -- Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a new study suggests that, for most common diseases, genes alone only tell part of the story. Their research shows the environment interacts with DNA in ways that are difficult to predict, even in simple organisms like single-celled yeast. ... > full story
Breast CT imaging system marches forward as pain-free tool to aid mammograms (December 3, 2010) -- While questions persist about the best ways to detect breast cancer early, a CT imaging system first unveiled five years ago is in a better position today to enter the fray -- at least in a supporting role to conventional mammography. ... > full story
Nicotine exposure in pregnant rats puts offspring at risk for learning disabilities (December 3, 2010) -- Exposure to nicotine during pregnancy leads to a decrease in adult stem cells and a change in synaptic plasticity in the hippocampus of the offspring, according to new research. Researchers say this could be a possible cause for behavioral problems such as attention-deficit hyperactivity disorder seen in children whose mothers smoked. ... > full story
Dementia may result from incomplete memories (December 3, 2010) -- Memory difficulties such as those seen in dementia may arise because the brain forms incomplete memories that are more easily confused, new research has found. Currently, memory problems are typically perceived to be the result of forgetting previously encountered items or events. The new research however, found that the ability of the brain to maintain complete, detailed memories is disrupted. ... > full story
Anesthetic gases heats climate as much as one million cars, new research shows (December 3, 2010) -- One kilo of anesthetic gas affects the climate as much as 1,620 kilos of carbon dioxide, according to a recent study carried out by a team of chemists and anesthesiologists. The amount of gas needed for a single surgical procedure is not high, but each year surgery related anesthetics affects the climate as much as would one million cars, states a new report. ... > full story
Brittle bones and heart disease go hand in hand (December 3, 2010) -- Norwegian studies indicate that people with osteoporosis have a greater risk of developing cardiovascular disease, and vice versa.
