Demand for Covid-19 vaccinations has fallen so dramatically in Georgia that the state has been turning down millions of allocated doses, telling the federal government to distribute them elsewhere. Joshua Weitz, Patton Distinguished Professor and Co-Director of the Interdisciplinary Ph.D. in Quantitative Biosciences in the School of Biological Sciences, is part of a team that’s attempted to estimate the level of immunity via prior infection and vaccination in the U.S. and in each state. Weitz estimates about 60% of Georgians have some level of immunity. But millions remain unprotected.

A new international study has cast doubts on the view that variations in the density of some of the deepest currents of the subpolar North Atlantic Ocean are caused by winter surface conditions and represent changes in the strength of the Meridional Overturning Circulation (MOC). The study was co-led by Susan Lozier, Professor in the School of Earth and Atmospheric Sciences, and Dean and Betsy Middleton and John Clark Sutherland Chair in the College of Sciences. Lozier, a physical oceanographer, is president of the American Geophysical Union (AGU.) (The study was also covered on the Subsea UK website.)

New findings in a study by researchers from Georgia Tech and Emory University could point the way to a therapeutic treatment for Alzheimer's with the potential to slow the incurable disease's advance. The study, published this month in the journal Alzheimer’s & Dementia: Translational Research & Clinical Interventions, examined whether a technique of flickering lights and sound - which has been found to reduce Alzheimer's in mice - was viable to try with humans. Qiliang He, a postdoctoral fellow in the School of Psychology, is first author for the study. 

This research team studying problems in tropical geometry includes Bo Lin, a visiting assistant professor/postdoctoral scholar in the School of Mathematics. Lin also researches at  Georgia Tech's Southeast Center for Mathematics and Biology.
