Q&A: Is chocolate healthy?

February 10, 2023

As Valentine’s Day approaches, the mind naturally turns to love — and chocolate. To learn more about chocolate and its effects on us, we spoke with Joshua Lambert, professor of food science at Penn State. Lambert’s research focuses on diet, specifically adopting dietary practices to prevent cancer, obesity and inflammation. He has worked extensively with cocoa, the key ingredient in chocolate.

Controlled, localized delivery of blood thinner may improve blood clot treatment

January 5, 2023

Heparin has long been used as a blood thinner, or anticoagulant, for patients with blood clotting disorders or after surgery to prevent complications.
