Biologist Lucia Strader in Arts & Sciences discovered a cellular transporter that links two of the most powerful hormones in plant development — auxin and cytokinin — and shows how they regulate root initiation and progression. Understanding why and how plants make different types of root architectures can help develop plants that better cope with distinct soil conditions and environments.

A native mosquito in Missouri has fewer parasites when it shares its waters with an interloper, according to new research from biologists at Tyson Research Center, the environmental field station for Washington University in St. Louis.

A new study reveals the surprising way that family quarrels in seeds drive rapid evolution. Conflict over resources seems to play a special role in the development of certain seed tissues, according to Washington University in St. Louis research led by David Queller and Joan Strassmann in Arts & Sciences.

Researchers in Arts & Sciences at Washington University in St. Louis have figured out how to feed electricity to microbes to grow truly green, biodegradable plastic, as reported in the Journal of Industrial Microbiology and Biotechnology.

Marie Kondo herself couldn’t do it any better. Now researchers at Washington University in St. Louis have uncovered a previously unknown structural feature of living cells that is critical to tidying up.

Researchers led by Kenneth M. Olsen in Arts & Sciences used a new imaging technique to reveal a takeover strategy that has worked for weedy rice over and over again: roots that minimize below-ground contact with other plants.

Led by Arpita Bose, assistant professor of biology in Arts & Sciences, a Washington University team showed how an electricity-eating microbe takes up electrons from conductive substances like metal oxides or rust to reduce carbon dioxide. The work is described in the journal Nature Communications.

Erik Herzog, professor of biology in Arts & Sciences, studies the molecules, cells and circuits of mammalian circadian timing. He also supports and encourages younger neuroscience researchers, from elementary school all the way through doctoral programs.

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.
