Emotion And Scent Create Lasting Memories -- Even In A Sleeping Brain (October 17, 2008) -- In a series of experiments with sleeping mice, researchers at the Duke University Medical Center have shown that the part of the brain that processes scents is indeed a key part of forming long-term memories, especially involving other individuals. ... > full story

Border Control: How Proteins Permit Entry To A Cell (October 17, 2008) -- The means by which proteins provide a 'border control' service, allowing cells to take up chemicals and substances from their surroundings, whilst keeping others out, is revealed in unprecedented molecular detail for the first time, in the journal Science. ... > full story

Human Microbiome Consortium To Investigate Role Of Microbes In Human Health And Disease (October 17, 2008) -- Scientists from around the globe have formed the International Human Microbiome Consortium, an effort that will enable researchers to characterize the relationship of the human microbiome in the maintenance of health and in disease. ... > full story

Medical Textbooks Use White, Heterosexual Men As A 'Universal Model' (October 17, 2008) -- Images of white men predominate in western anatomy textbooks, which present them as a "universal model" of the human being. This is the main conclusion of a study that has analysed 16,329 images from 12 manuals currently recommended by 20 of the most prestigious universities in Europe, the United States and Canada. ... > full story

Gene Screen To Identify Causes Of Autism (October 17, 2008) -- A new screening method can be used to detect the chromosomal abnormalities most commonly associated with autism spectrum disorders. By screening for genetic defects associated with various kinds of cognitive impairment, the approach will help clinicians identify the underlying causes of some patients' autism spectrum disorders. ... > full story

Nanotechnology Boosts War On Superbugs (October 17, 2008) -- Scientists are using nanotechnology to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as MRSA. The researchers developed ultra-sensitive probes capable of providing new insight into how antibiotics work, paving the way for the development of more effective new drugs. ... > full story

Prostate Cancer Gene Test Provides New Early Detection (October 17, 2008) -- Currently, early detection of prostate cancer depends on an abnormal digital rectal examination and an elevated prostate-specific-antigen (PSA) level requiring a prostate biopsy, often associated with anxiety, discomfort, complications, and heavy expenses. Now researchers have developed a test using a new PCa gene-based marker that can be carried out with a urine sample. ... > full story

Better Beer: College Team Creating Anticancer Brew (October 17, 2008) -- College students often spend their free time thinking about beer, but a group of Rice University students are taking it to the next level. They're using genetic engineering to create beer that contains resveratrol, a chemical in wine that's been shown to reduce cancer and heart disease in lab animals. ... > full story

Bugs In The Gut Trigger Production Of Important Immune Cells, Study Finds (October 17, 2008) -- A new study reveals that specific types of bacteria in the intestine trigger the generation of pro-inflammatory immune cells, a finding that could eventually lead to novel treatments for inflammatory bowel disease and other diseases. ... > full story

Neuroscientist Finds Transplanted Hand-to-brain Mapping 35 Years After Loss Of Limb (October 17, 2008) -- Four months after a successful hand transplant -- 35 years after amputation in an industrial accident at age 19 -- a 54-year-old man's emerging sense of touch is registered in the former "hand area" of the his brain, says a University of Oregon neuroscientist. ... > full story

Disease Leads To Vision Loss More Often In Men (October 17, 2008) -- A new study shows that men are more likely to lose vision as a result of a particular cause of intracranial hypertension, or increased pressure in the brain, than women with the condition. ... > full story

ER Staffs: Gaps Exist In Hospital Preparedness For Dirty Bombs (October 17, 2008) -- Serious challenges remain in radioactivity readiness, according to a new study that finds emergency room doctors and nurses worry that hospitals are not adequately prepared to handle casualties from a radioactive 'dirty bomb.' Among the concerns is whether ER staffers, in a dirty bomb scenario, could protect themselves and give appropriate care, the study authors said. ... > full story
