Scientists watch a black hole shredding a star
A NASA satellite searching space for new planets gave astronomers an unexpected glimpse at a black hole ripping a star to shreds. The milestone was reached with the help of a worldwide network of robotic telescopes headquartered at The Ohio State University called ASAS-SN (All-Sky Automated Survey for Supernovae). Astronomers from the Carnegie Observatories, Ohio State and others published their findings today in The Astrophysical Journal.
Protein Intake, Physical Function in Older Adults Differs Dramatically by Ethnicity/Race
A cross-sectional study examined differences in protein intake, nutritional status, and physical health (muscle strength and function) among older African Americans, European Americans and Hispanic Americans. The study is the first to evaluate these physical health indicators in association with protein intake among different racial/ethnic groups. A contributing factor to the age-related changes in muscle is insufficient protein intake by older adults. Findings highlight the need for further education and evidence-based interventions to support this vulnerable population.

Native American Burning Key to Rare Oak Savannas
In a recent article in Annals of the American Association of Geographers, geographers from the State University of New York (SUNY) found that Native American land use—in particular, the use of fire—was critical in shaping the distribution of oak savannas in Western New York at the end of the 1700s.
Researchers Discover New, Treatable Pathway Known to Cause Hypertension in Obese People
There’s no question that as body weight increases, so too does blood pressure. Now, in a study of mice, Johns Hopkins researchers have revealed exactly which molecules are likely responsible for the link between obesity and blood pressure. Blocking one of these molecules — a signaling channel that’s found in a tiny organ on the side of your neck — effectively lowers blood pressure in obese mice, the researchers reported recently in the journal Circulation Research.
