(Phys.org)—Meandering along the water-filled highways laced through an alternative membrane for fuel cells, protons visit sulfur and oxygen atom clusters along the way, according to scientists at Pacific Northwest National Laboratory. The highways are lined with identical hook-shaped molecules. Each channel contains a shell that keeps the water in, formed by the molecules' backbones. The small clusters, known as sulfonate groups, dangle inside the channel. In the middle is a thin "wire" of water.
An ultra-fast, 320-detector computed tomography scanner can accurately sort out which people with chest pain need -- or don't need -- an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study.
Mice develop pancreatic diabetes when they lack certain genes in the E2F group, and to understand how this happens, scientists have focused on the molecular mechanism behind it.
Studies have found that it is difficult to keep weight off in the long term. For post-menopausal women, natural declines in energy expenditure could make long-term weight loss even more challenging. A new study finds that in post-menopausal women, some behaviors related to weight loss in the short term are not effective or sustainable for the long term. Interventions targeting these behaviors could improve long-term obesity treatment outcomes.
Antibiotic residues in uncured pepperoni or salami meat are potent enough to weaken helpful bacteria that processors add to acidify the sausage to make it safe for consumption, according to a new study.
The risk of ischemic stroke one year after acute myocardial infarction (AMI) dropped by 21% over a ten year period, according to new research.
Within milliseconds, and just with the help of mathematics, computing power and conventional video cameras, computer scientists can automatically capture the movements of several people. The new approach helps not only animation specialists in Hollywood movies but also medical scientists and athletes.
Deep brain stimulation may stop uncontrollable shaking in patients with Parkinson’s disease and essential tremor by imposing its own rhythm on the brain, according to two recent studies.
Engineering researchers have developed a method to simplify the pharmaceutical production of proteins used in drugs that treat a variety of diseases and health conditions, including diabetes, cancer, arthritis and macular degeneration.

Improved treatment after acute myocardial infarction and less severe patient profile have reduced 30-day mortality over the past 15 years, according to new research.
Furry, agile, intelligent and voracious: the raccoon is far from being a cuddly toy, which is what many people believe when they get one as a pet. It is more like an invader that escapes and is able to adapt and survive in new habitats. According to a study, its expansion across Spain and Europe is bringing infectious and parasitic diseases like rabies.
