Brown biologist solves mystery of tropical grasses' origin
Brown University
Around 30 to 40 million years ago, grasses on Earth underwent an epic evolutionary upheaval. An assemblage capitalized on falling levels of atmospheric carbon dioxide by engineering an internal mechanism to concentrate the dwindling CO2 supply that, like a fuel-injection system in a car, could more efficiently convert sunlight and nutrients into energy.

Drug shows promise for Huntington's disease
University of Rochester Medical Center
An early stage clinical trial of the experimental drug dimebon (latrepirdine) in people with Huntington's disease appears to be safe and may improve cognition. That is the conclusion of a study published today in the Archives of Neurology.

The private sale of drugs in public hospitals
Canadian Medical Association Journal
Governments are under increasing pressure to provide access to expensive new drugs. Canadian patients who want access to drugs that are not publicly insured are seeking to pay for these drugs within public hospitals.

Study reveals new details on the dangers of third-hand smoke
DOE/Lawrence Berkeley National Laboratory
Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens.

Nicotine replacement therapy is over-promoted since most ex-smokers quit unassisted
Public Library of Science
Health authorities should emphasize the positive message that the most successful method used by most ex-smokers is unassisted cessation, despite the promotion of cessation drugs by pharmaceutical companies and many tobacco control advocates.

Study examines course and treatment of unexplained chest pain
JAMA and Archives Journals
Fewer than half of individuals who have "non-specific" chest pain (not explained by a well-known condition) experience relief from symptoms following standard medical care, according to a report in the February 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Hypertension may predict dementia in older adults with certain cognitive deficits
JAMA and Archives Journals
High blood pressure appears to predict the progression to dementia in older adults with impaired executive functions (ability to organize thoughts and make decisions) but not in those with memory dysfunction.

High-altitude climbs may cause corneal swelling, but do not appear to affect vision
JAMA and Archives Journals
Swelling commonly occurs in the corneas of mountain climbers, but does not appear to affect vision at altitudes of up to 6,300 meters (about 20,670 feet), according to a report in the February issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Depressed people feel more gray than blue
BioMed Central
People with anxiety and depression are most likely to use a shade of gray to represent their mental state. Researchers writing in the open access journal BMC Medical Research Methodology describe the development of a color chart, The Manchester Color Wheel, which can be used to study people's preferred pigment in relation to their state of mind.

Usual care often not consistent with clinical guidelines for low back pain
JAMA and Archives Journals
Australian general practitioners often treat patients with low back pain in a manner that does not appear to match the care endorsed by international clinical guidelines, according to a report in the February 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Gadgets not related to teenagers' brain pain
BioMed Central
Use of most electronic media is not associated with headaches, at least not in adolescents. A study of 1025 13-17 year olds, published in the open access journal BMC Neurology, found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was associated with a pounding head.

Lower detection of prostate cancer with PSA screening in US than in a European randomized trial
Journal of the National Cancer Institute
Fewer prostate cancers were detected by prostate-specific antigen (PSA) screening in the U.S. than in a European randomized trial because of lower screening sensitivity, according to a new brief communication published online February 8 in the Journal of the National Cancer Institute.
