The movement to abolish clock-time changes each spring and fall is growing — and so is the scientific evidence. Experts say perennial standard time, or “wintertime,” is the best and safest option for public health.

Joshua Blodgett, assistant professor of biology in Arts & Sciences, received a five-year $900,500 grant to support his research related to actinomycete bacteria. This type of bacteria produces a majority of current antibiotics and may harbor other useful small molecules that could be revealed by activating silent genes.

A new study led by Petra Levin in Arts & Sciences suggests that triclosan exposure may inadvertently drive bacteria into a state in which they are able to tolerate normally lethal concentrations of antibiotics — including those antibiotics that are commonly used to treat urinary tract infections.

New research from Washington University in St. Louis shows that honey bees (Apis mellifera) develop different scent profiles as they age, and the gatekeeper bees at the hive’s door respond differently to returning foragers than they do when they encounter younger bees who have never ventured out before.

Purple rice is a whole grain with high levels of antioxidants — and high levels of genetic diversity, thanks to traditional farming practices, according to new research from Washington University in St. Louis.

A new paper co-authored by the School of Engineering & Applied Science’s Michael Vahey on a new way to study influenza gives researchers insights into how this virus remains so successful in humans — and ultimately how to fight it.

A favorite Halloween symbol leaves behind clues to what a tropical landscape looked like thousands of years ago. With support from the Living Earth Collaborative, postdoctoral scholar Rachel Reid of Arts & Sciences digs in.

Petra Levin, professor of biology in Arts & Sciences, was recently awarded a $2 million grant to identify and characterize the molecular circuits that coordinate or limit the growth and reproduction of bacteria.

By activating a small subset of the neurons involved in setting daily rhythms, biologist Erik Herzog in Arts & Sciences has unlocked a cure for jet lag in mice, as reported in a July 12 advance online publication of Neuron.

In a growing plant cell, motor proteins called kinesins work as transporters that haul materials built in one part of the cell to the place where they are needed. Now, biologists at Washington University in St. Louis have discovered the molecular brakeman that holds kinesins in check until their cargo is needed.
