Learning the language of bacteria

MADISON — Bacteria are among the simplest organisms in nature, but many of them can still talk to each other, using a chemical “language” that is critical to the process of infection. Sending and receiving chemical signals allows bacteria to mind…

Growing drought-tolerant crops inching forward

A collaborative team of scientists led by researchers at The Medical College of Wisconsin, in Milwaukee, has used the tools of structural biology to understand how a synthetic chemical mimics abscisic acid (ABA), a key stress hormone that helps plan…

Brighter Neptune suggests a planetary change of seasons

progressive increase in the brightness of the planet Neptune suggests that, like Earth, the distant planet has seasons. Observations of Neptune made during a six-year period with NASA’s Hubble Space Telescope by a group of scientists from the University of Wisconsin-Madison and NASA’s Jet Propulsion Laboratory (JPL) show that the planet is exhibiting a significant increase in brightness. The changes, observed mostly in the planet’s southern hemisphere, show a distinct increase in the amount and brightness of the banded cloud features that are a distinctive feature of the planet.
