Most glaucoma patients don't ask about medication costs

A recent study found that less than one-third of glaucoma patients discuss medication costs with their doctor. High costs are a significant barrier to adherence, and doctors should consider discussing medication costs during visits to prompt a discussion. The study analyzed video recordings of 275 office visits and suggested further re...

To drop CO2 emissions, look to local transportation and housing

According to a new study from the University of Pennsylvania, local efforts in residential housing and transportation can significantly reduce CO2 emissions. The researchers found that adopting energy-conservation standards in housing could reduce emissions by 31-46% by 2030, while a fuel-economy standard of 40 mpg could reduce transpo...
