When temperatures drop, newly-discovered process helps fruit flies cope

July 21, 2014

Rochester biologist Michael Welte and his team made their discovery while studying the internal mechanisms of the egg cell of the fruit fly, known as Drosophila. What keeps the assembly line functioning—based on the new research—is a protein called Klar.

How Do Blind Mole Rats Ward Off Cancer?

How Do Blind Mole Rats Ward Off Cancer?

November 7, 2012

Blind mole rats and naked mole rats—both subterranean rodents with long life spans—are the only mammals never known to develop cancer. Rochester biologists have now determined that the mechanism for fighting off cancer differs between the two.
