Viewing a video showing a patient with advanced dementia may help elderly patients plan for end-of-life care, according to a study led by Massachusetts General Hospital researchers. The investigators found that participants who watched such a video in addition to listening to a verbal description of the condition were more likely choose receiving comfort care if they developed advanced dementia...
Mice carrying a "humanized version" of a gene believed to influence speech and language may not actually talk, but they nonetheless do have a lot to say about our evolutionary past, according to a report in the May 29 issue of the journal Cell, a Cell Press publication.

Many songbirds learn their songs early in life from a role model. In the absence of an appropriate tutor, they develop an improvised song that often lacks the species-typical song structure. However, male canaries even learn to sing normal songs when they were exposed as juveniles to tutors that lacked the features of normal canary song, as researchers from the Max Planck Institute for Ornithology...
This paper explores the importance of dispersal to the evolution of parasites and suggests that as human activity makes the world more connected, natural selection will favor more virulent and dangerous parasites.
Premature ejaculation can be embarrassing, but a new study suggests that it might be a genetic disorder.
As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere.
Watching people's brains in real time as they handle a set of decision-making problems can reveal how different each person's strategy can be, according to neuroscientists at the Duke University Medical Center.

Effects associated with several commonly-prescribed dementia drugs may be putting elderly Canadians at risk, says Queen's University geriatrics professor Sudeep Gill.
A generation of DNA-like compounds, class R inhibitory oligonucleotides, have been shown to effectively inhibit cells responsible for the chronic autoimmune condition lupus. Researchers writing in BioMed Central's open access journal Arthritis Research and Therapy have demonstrated the anti-inflammatory effects of the INH-ODNs in both in vitro and mouse experiments.
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.
Advertisements shown during children's television before new restrictive regulations were introduced were not any more focused on unhealthy food than adverts shown at other times, according to research published ahead of print in the Archives of Disease in Childhood.
New guidelines designed to standardize and optimize the diagnosis, treatment, and monitoring of patients with medullary thyroid carcinoma , an uncommon and challenging form of thyroid cancer, have been developed by the American Thyroid Association and published online ahead of print in Thyroid, a peer-reviewed journal published by Mary Ann Liebert Inc. The guidelines are available free online.
Despite the well-known benefits of having a lifestyle that includes physical activity, eating a diet high in fruits and vegetables, maintaining a healthy weight, moderate alcohol use and not smoking, only a small proportion of adults follow this healthy lifestyle pattern, and in fact, the numbers are declining, according to an article published in the June 2009 issue of the American Journal of...
Sulfolobus islandicus, a microbe that can live in boiling acid, is offering up its secrets to researchers hardy enough to capture it from the volcanic hot springs where it thrives. In a new study, researchers report that populations ofS. islandicus are more diverse than previously thought, and that their diversity is driven largely by geographic isolation.
A Canadian researcher working in the UK says doctors, authors and educators are doing hyperactive children a disservice by claiming that hyperactivity as we understand it today has always existed.
A landmark clinical trial led by a University of North Carolina at Chapel Hill researcher concludes that radiofrequency ablation is an effective treatment for dysplasia in people with Barrett's esophagus, a condition that can lead to deadly gastrointestinal cancer. The study is published in the May 28, 2009 issue of the New England Journal of Medicine.
Research led by the University of Leicester suggests people today and in future generations should look to the past in order to mitigate the worst effects of climate change.
Our brain is wired to identify gender based on facial cues and coloring, according to a new study published in the Journal of Vision. Psychology Professor Frederic Gosselin and his Universite de Montreal team found the luminescence of the eyebrow and mouth region is vital in rapid gender discrimination.
Researchers have discovered a novel molecular path that predisposes patients to develop primary biliary cirrhosis, a disease that mainly affects women and slowly destroys their livers. Primary biliary cirrhosis has no known cause.
A melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and in Canada, according to new research led by NCAR.
When Chicago Blackhawk's leading scorer Martin Havlat returned to the ice for game four of the Western Conference Final after sustaining a concussion only two days earlier, questions were raised surrounding his swift return.
