Increasing solar power generation in the U.S. by 15% could lead to an annual reduction of 8.54 million metric tons of carbon dioxide (CO2) emissions, according to a new study led by Harvard T.H. Chan School of Public Health. The researchers found that the climate benefits of solar power differ markedly across U.S. regions, pinpointing where clean energy investments return the greatest climate dividends.

Rising temperatures in California are causing fewer cold-related deaths, outweighing heat-related deaths. But hotter temperatures are increasing emergency department visits, placing a greater burden on the healthcare system, report UC San Diego and Stanford University researchers.

In a new study, researchers found that novel eye-tracking metrics can help properly identify concussion-related vision disorders, a common phenomenon among patients with persisting post-concussive symptoms that last more than 28 days after their initial injury.
