New risk factors for retinal disorder identified
Antibiotics, antihistamines, alcohol use, tobacco use, untreated hypertension and multisystem autoimmune diseases are potential risk factors for a retinal disorder known as central serous chorioretinopathy.

Activation of receptor ups development of precancerous intestinal polyps
Vanderbilt-Ingram Cancer Center researchers have provided the first evidence that activation of a particular cellular receptor dramatically increases the development of precancerous polyps in the intestine.

Pacifying bacteria prevents lethal post-op infections
D├ętente may be better than assault in the war between man and microbe.

Change in social policies could reduce high rate of depression in men who have sex with men
Recent experience as the target of anti-gay violence or threats, not identifying as gay, or feeling alienated from the gay community are the major predictors of depression in men who have sex with men (MSM) and public health officials should address these issues by seeking changes in social policies, say UCSF researchers.

UN report: Accelerate global agreement to oversee exploitation of South Pole 'extremophiles'
Work should be stepped up on international agreements to oversee prospecting efforts in Antarctica by research institutions, universities and pharmaceutical companies to discover and stake ownership to promising organisms and compounds with genetic properties that make survival possible in extremely cold, arid and salty conditions, says a new report from UN University.

Eye disease may cause sleep disorders
A study appearing in the February issue of Ophthalmology--the clinical journal of the American Academy of Ophthalmology, the Eye M.D.

Microbial biofilm yields community genomes, metabolic clues
Examining life extracted from toxic runoff at a northern California mine, researchers for the first time have reconstructed multiple individual genomes from a microbial community taken from an environmental sample rather than from a laboratory culture.

Scientists report first sequencing of environmental genome
Only one percent of all microbes can be cultured for sequencing of their DNA, so scientists have been trying a more direct approach - sequencing a community of microbes plucked out of the environment.

Optic nerve disease may cause sleep disorders
Young people with eye diseases that damage the inner part of the retina and optic nerve are significantly more likely to have sleep disorders than those with other types of eye disease or those with normal vision. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
