What Can Snakes Teach Us About Engineering Friction?

If you want to know how to make a sneaker with better traction in the rain, just ask a snake. That’s the theory driving the research of

Hisham Abdel-Aal, PhD, an associate teaching professor in Drexel University’s College of Engineering who is studying snake skin to help engineers improve the design of textured surfaces, such as engine cylinder liners, prosthetic joints — and yes, maybe even footwear.

'Non-Smoking' Doesn't Mean Smoke-Free — Drexel Study Finds Third-Hand Smoke Spreads Inside

Despite decades of indoor smoking bans and restrictions, new research from Drexel University suggests the toxins we’ve been trying to keep out are still finding their way into the air inside. Findings by a group of environmental engineers show that third-hand smoke, the chemical residue from cigarette smoke that attaches to anything and anyone in the vicinity of a smoke cloud, can make its way into the air and circulate through buildings where no one is smoking.

Malaria-Carrying Parasites Spread More When They Can Jump Into Multiple Birds - Study

A study out of the Academy of Natural Sciences of Drexel University found that blood parasites that cause malaria spread more widely if they can use many different kinds of birds as hosts. But even those "generalist" parasites are limited.
