Between the low supply of, and high competition for, some key nutrients like nitrogen in the open ocean, scientists have puzzled over the vast diversity of microbial species found there. Researchers from 13 institutions show that time of day is key, according to a study published in Nature Ecology & Evolution. Georgia Tech collaborators for the study include Joshua Weitz, Professor and Tom and Marie Patton Chair in the School of Biological Sciences; Daniel Muratore, a doctoral candidate in the Quantatative Biosciences program, and Rogelio Rodriguez-Gonzalez, a graduate student in the School of Biological Sciences.

Rapid tests are a quick and easy way to find out if you’ve contracted Covid-19, but some tests may not detect variants of the virus. “The chances are a little bit more that those kinds of tests will not detect the new variant,” says M.G. Finn, Professor and Chair in the School of Chemistry and Biochemistry, and James A. Carlos Family Chair for Pediatric Technology. Rapid tests, also known as antigen tests, seek and grab ahold of specific proteins around the outside shell of the virus. Variants can alter those proteins, Finn says. If it changes the specific protein the test was designed for, you can get false negatives.
