Penn State gearing up for 2017 solar eclipse event
This unique map shows the path of the moon’s umbral shadow—in which the sun will be completely obscured by the moon—during the total solar eclipse of August 21, 2017, as well as the fraction of the sun’s area covered by the moon outside the path of totality.

New, more sensitive sensor for evaluating drug safety
Image of cells expressing the AgHalo sensor before (left) and after (right) cellular stress. The AgHalo sensor is turned on when misfolded proteins begin to aggregate and provides a quantitative measure of cellular stress that can be used to evaluate drug safety.

New way to weigh a white dwarf: Use Hubble Space Telescope
This drawing shows the observed versus actual positions of a distant star whose light is distorted by the curvature of space around a heavy star that is between the distant star and the observer. In this case, the observer is the Hubble Space Telescope. Credits: NASA, ESA, and K. Sahu (STScI)
