The radiology tech waved me into his cozy dark room filled with bright screens. It’s usually off-limits to patients, but maybe he knew I was a local doctor and faculty member at Harvard Medical School, which can occasionally get me a backstage pass. With a smirk, he told me I should eat something, pointing at…
Could competitive cyclists be putting their bone health at risk? A disquieting new study of bone density in elite cyclists and runners suggests that the answer might be yes. The study found that the cyclists, both male and female, had thinner bones than the runners, even though all of the athletes were young, healthy and…

Vaccinating laboratory mice with Streptococcus mitis bacteria prevents their virulent sibling, Streptococcus pneumoniae from infecting the mice. The research suggests that vaccination of humans with live S. mitis might offer protection from some of the many serotypes of S. pneumoniae that vaccines currently do not exist for. This pathogen is one of the most common…
DALLAS, Jan. 30, 2019 — Stroke survivors who believe they can protect themselves from having another stroke had more than twice the blood pressure reduction of nonbelievers, according to preliminary research to be presented in Honolulu at the American Stroke Association’s International Stroke Conference 2019, a world premier meeting for researchers and clinicians dedicated to…
MIT engineers have designed an ingestible, Jell-O-like pill that, upon reaching the stomach, quickly swells to the size of a soft, squishy ping-pong ball big enough to stay in the stomach for an extended period of time. The inflatable pill is embedded with a sensor that continuously tracks the stomach’s temperature for up to 30…
DALLAS, January 30, 2019 — Rising temperatures stemming from global climate change may increase the number of infants born with congenital heart defects (CHD) in the United States over the next two decades and may result in as many as 7,000 additional cases over an 11 year-period in eight representative states (Arkansas, Texas, California, Iowa,…
