Scientists use E. coli TGT as a primary model to understand how TGT works in other bacteria, but have struggled to visualize its atomic structure. UC San Diego biochemistry professor Neal Devaraj’s lab has captured the first cryo-EM visualizations of E. coli TGT structure. This work may assist in drug-design efforts.

The study of nearly 45,000 first-time mothers found that repeated exposure to combinations of common air pollutants in early pregnancy was associated with nearly three-times greater odds of early preterm birth. Levels that the EPA's AQI would classify as "safe" may still pose health risks when experienced together. The most critical pregnancy window was weeks 9-14 of pregnancy, particularly around week 11, when the placenta and fetal blood supply are developing.
