How studying geckos can help the human healing process

Geckos can regenerate tissue and heal without scarring, and Prof. Matt Vickaryous, Biomedical Sciences, wants to understand how they do it. Learning how geckos avoid scars and still heal rapidly without excessive fluid loss and infection could help researchers find ways to improve the healing process in humans.

Where are the lions and other top predators?

Why aren’t there more lions when there’s plenty of prey on the African savanna? A team of researchers, including integrative biology professors John Fryxell and Kevin McCann, found that relative amounts of predator and prey biomass in diverse ecosystems around the globe are remarkably well-predicted by a simple mathematical function called a power scaling law.
