Weather forecasters talk about wind shear a lot during hurricane season, but what exactly is it?  School of Earth and Atmospheric Sciences Senior Academic Professional Zachary Handlos teaches meteorology in a part of the country that pays close attention to the Atlantic hurricane season. In this article, Handlos provides a quick look at wind shear, one of the key forces that can determine whether a storm will become a destructive hurricane.

In the vast stretches of Georgia's saltwater marshes, where the land whispers to the ocean, a silent yet profound battle is waged beneath the surface. It's a struggle for survival and resilience, where the unassuming cordgrass, Spartina alterniflora, emerges as an ecological champion. But not without the help of its unseen allies-the intricate microbial communities thriving within its roots. Recent studies by Georgia Tech researchers, including School of Biological Sciences Professor and Associate Chair of Research Joel Kostka, have unveiled the pivotal role these microbes play in not only sustaining the cordgrass but also in bolstering the health of the entire coastal ecosystem. These findings, published in Nature Communications, shed light on the complex interplay between plant and microbe, revealing a symbiotic relationship that is as delicate as it is powerful.

Evidence from the International Space Station suggests microbial populations are rapidly adapting to the spacecraft environment; however, the mechanism of this adaptation is not understood. Bacteriophages are prolific mediators of bacterial adaptation on Earth. In this study, researchers including School of Biological Sciences Ph.D. student Iris Irby, survey 245 genomes sequenced from bacterial strains isolated on the International Space Station for dormant (lysogenic) bacteriophages. The results correlate microbial adaptation in spaceflight to bacteriophage-encoded functions that may impact human health in spaceflight.
