"Small dinosaurs could have just run into the shade to cool off, but for those giant dinosaurs, the potential for overheating was literally inescapable," said study co-author Lawrence Witmer, a professor of anatomy at Ohio University in Athens, Ohio.

WEDNESDAY, Oct. 16, 2019 (American Heart Association News) -- Many people know treating high blood pressure reduces the odds of a heart attack, stroke or heart failure. Now, a new study suggests another added benefit: a lower risk of lesions in the brain that increase the chances of dementia, stroke and falls in older adults.
The study, published this week in the American Heart Association journal Circulation, included 199 women and men age 75 and older. They all had systolic blood pressure (the top number) of 150 or higher and brain MRIs showing lesions known as white matter hyperintensity lesions that are common in older adults.
