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.

Findings on the cellular-level regulation of proteins called histones by lipid droplets, or “fat depots,” shines light on chromosome production – and possible manipulation of that process.

A $9.5 million grant from the National Institute on Aging will support research into the factors responsible for longevity in various species of long-lived rodents, with the goal of developing treatments to improve the aging process in people.

Sina Ghaemmaghami has been recognized for “exemplifying the role” of teacher-scholar.

Daniel Scantlebury calls Madagascar “an ideal evolutionary laboratory” for studying species formation because it has long been isolated and geologically stable relative to other regions.

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.

Histones are proteins needed to assemble DNA molecules into chromosomes. New research at the University of Rochester is causing a fundamental shift in the concept of histone balance and the mechanism behind it.
