Climate change pushing up levels of methylmercury in fish

A new study concludes that while the regulation of mercury emissions have successfully reduced methylmercury levels in fish, spiking temperatures are driving those levels back up and will play a major role in the methylmercury levels of marine life in the future.

Harvard study suggests racial tension may stem from fear of exposure to infectious diseases

A postdoctoral fellow working in the lab of Psychology Professor Matt Nock,Brian O’Shea is the lead author of a study that suggests racial tension may stem not from different groups being exposed to each other, but fear of a different sort of exposure — exposure to infectious diseases. The study is described in a July 15 paper published in Social Psychological and Personality Science.

CBD risks and the chance to rein in supplements

A marijuana derivative called cannabidiol, or CBD, has begun making its way into supplements and even into foods, a use that runs afoul of an FDA designation of the compound as a prescription drug. A Harvard Medical School associate professor says CBD’s tangled legal status may provide an opportunity not only to clear up its status, but to bring clarity to the entire supplements industry.

Wyss researchers has electrifying insights into how bodies form

A researcher is reviving the study of bioelectricity to learn how cells communicate with each other to form tissues and organs, and how harnessing those signals could one day lead to truly regenerative medicine, in which amputees could simply regrow limbs.
