Climate change is making heat waves like this week's more common and severe in Pa.

A new study led by a Penn State biologist reveals that frogs have maintained a surprising number of nonvisual light-sensing proteins over evolutionary time. These proteins, called opsins, play a role in a variety of biological functions including calibration of circadian rhythm, melatonin release, pupil response, and detection and response to seasonal changes.
