Did Modern Maladies Help Our Ancestors Survive?
Psoriasis, a chronic skin condition, can cause rashes that itch and sting. So why would a genetic susceptibility to this and other ailments persist for hundreds of thousands of years, afflicting our ancient ancestors and us? That's what scientists...

Flipping Tools for the Science Classroom
With the spread of flipped instruction (video lectures watched at home and "homework" done in class) and blended learning opportunities (traditional methods combined with computer-mediated activities), we see a dynamic shift away from the lecture-based...
