Researchers from the George Washington University and the Moscow Institute of Physics and Technology have developed a solution for multiparametric optical mapping of the heart's electrical activity. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. Arrhythmia causes your heart to beat too quickly, too slowly or erratically. Hijacking the heart's vital rhythm and pumping function can have serious consequences like a stroke or cardiac arrest.

Prof. Wu Yuen's team successfully prepared a kind of catalyst which is able to significantly accelerate oxygen evolution reaction, which help human get one step further in pursuing applicable hydrogen fuel.

Researchers from Mount Sinai and IBM reveal that the number of mitochondria in a cell is, in great part, associated with how the cancer responds to drug therapy.

According to the US Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, in ACS Nano, researchers report development of a membrane that helps periodontal tissue regenerate when implanted into the gums of rats.

State breast density notification laws that mandate reporting of mammogram results can prompt further screening and modestly boost cancer detection rates, say researchers at Yale's School of Public Health and School of Medicine. Their study was published in the American Journal of Public Health.

Here's something to chew on: One in four people are impacted by defects of the temporomandibular - or jaw - joint. Despite the pervasiveness of this affliction, treatments are lacking, and many sufferers resort to palliative measures to cope with the pain and debilitation it causes.

By conjuring the spell 'Lumos!' wizards in the mythical world of Harry Potter could light up the tip of their magic wands and illuminate their surroundings. So, too, does LumosVar, a computer program developed by the Translational Genomics Research Institute (TGen), 'light up' cancer-causing genetic Var-ients, or mutations, illuminating how physicians might best treat their patients.
