A class of speech sounds that is now present in nearly half of the world’s languages - labiodentals, produced by positioning the lower lip against the upper teeth, such as in ‘f’ or ‘v’ - are a relatively recent development, one brought about by post-Neolithic diet-induced changes in the human bite. That’s according to a [...]
The more sugar-sweetened beverages (SSBs) people consumed, the greater their risk of premature death--particularly death from cardiovascular disease, and to a lesser extent from cancer, according to a large long-term study of US men and women. The risk of early death linked with drinking SSBs was more pronounced among women.
The NASA/ESA Hubble Space Telescope has produced this beautiful image of an elliptical galaxy called Messier 49. Unlike spiral galaxies, which have a well-defined structure and boast picturesque spiral arms, elliptical galaxies appear fairly smooth and featureless. They tend to contain a larger portion of older stars than spiral galaxies and also lack young blue [...]
Alzheimer’s disease, which affects more than 5 million people in the United States, is characterized by beta-amyloid plaques that are suspected to be harmful to brain cells and to interfere with normal brain function. A unique non-invasive technique using flickering light successfully reduced amyloid plaques and improved memory impairments in a mouse model of Alzheimer’s [...]
The study of more than 1,000 patients with severe heart failure not only confirms that the HeartMate 3™, a next-generation LVAD device, markedly reduced the need for re-operations due to pump malfunctions, but also found that it lowered risk of bleeding events and strokes, compared to the HeartMate II™.
Heart attack prevention and outcomes have dramatically improved for American adults in the past two decades, according to a new study. Compared to the mid-1990s, Americans today are less likely to have heart attacks and also less likely to die from them, said the researchers.
Sixty million kids participate in organized athletics each year with ever increasing amounts of children specializing in one sport before the age of 14 with hopes of a college scholarship or professional career on the line. However, researchers today reveal that this early intense participation might come at the cost of increased injuries during their athletic careers.
Anterior Cruciate Ligament (ACL) reconstruction patients often face bone and muscle loss immediately following the procedure. Researchers note that combining blood flow restriction (BFR) therapy with traditional rehabilitation efforts may slow bone loss and reduce return to function time.
Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond.
Scientists have completed one of the largest and longest examinations to trace unprocessed nitrate movement in forests. The team found that some nitrate occasionally moves too fast for biological uptake, resulting in 'unprocessed' nitrate bypassing the otherwise effective filter of forest biology.
Research performed over the last several decades has led to an increased understanding of the genetics of cancer. The clinical application of this knowledge for pediatric cancer has lagged behind studies performed for adults. Medical researchers now survey the landscape of this young field and present opportunities for using genomic information to advance a new era of care for children with cancer.
