A sixth-grade science fair project in 2014 led to the discovery that erythritol, the main component of Truvia, is a natural insecticide. Today, that discovery is the basis of a new Drexel-backed startup, BioLogic Insecticide. Simon D. Kaschock-Marenda, now a freshman at Drexel in the College of Engineering, was 11 when he noticed that Drosophila melanogaster, commonly known as fruit flies, died much quicker when they fed on Truvia than on other sweeteners. His father, Daniel Marenda, PhD, professor of biology in the College of Arts and Sciences, was unconvinced at first.

The typical images that “climate change” conjures include disappearing coastlines and melting polar ice. But what about animals’ brains — including our own? Can they be affected by the changing climate? Sean O’Donnell, PhD, professor in the College of Arts and Sciences, argues that they absolutely can.
