On the early Earth, methane production could have persisted in rust-free patches of ancient seas. Unlike the situation in today’s well-aerated oceans, where most natural gas produced on the seafloor is consumed before it can reach the surface, most of this ancient methane would have escaped to the atmosphere to trap heat from the early sun.
Raquel L. Lieberman is the recipient of the 2017 Sigma Xi Best Faculty Paper Award. Lieberman is an associate professor in the School of Chemistry and Biochemistry. The paper recognized by this award is “Enzymatic hydrolysis by transition-metal-dependent nucleophilic aromatic substitution,” published in Nature Chemical Biology.
The National Science Foundation's "Discovery Files" radio feature has highlighted the work of Brian Hammer, Will Ratcliff, Samuel Brown, and Peter Yunker in a 90-second audio feature titled "A Gut Reaction." The feature was based on a paper published on Feb. 6, 2017 in the journal Nature Communications.
Following Dean Gary May’s confirmation as the next chancellor at the University of California Davis, Provost Rafael L. Bras has named a search committee to launch a national and international search for a new dean of the College of Engineering. The committee will be chaired by Julia Kubanek, associate dean for Research, College of Sciences; professor of Biological Sciences; and professor of Chemistry and Biochemistry.
Metals from brakes and other automotive systems are emitted into the air as fine particles, lingering over busy roadways. Now, researchers at Georgia Institute of Technology have shown how that cloud of tiny metal particles could wreak havoc on respiratory health.
Researchers have successfully identified biological signatures in pediatric patients with newly diagnosed Crohn’s disease (CD) capable of predicting whether a child will develop disease-related complications requiring major surgery within three to five years. The results of this research, “Prediction of complicated disease course for children newly diagnosed with Crohn’s disease: a multicentre inception cohort study,” have been published in the journal, The Lancet.
For his achievements so far, the University System of Georgia (USG) last year named Nick Hud a Regents Professor. This honor is the highest bestowed by USG for distinction and achievement in teaching and scholarly research. Understanding how chemistry begat biology is one of the grand challenges of science. It is the focus of Hud’s research and of the Center for Chemical Evolution (CCE), which Hud directs. The CCE has positioned Georgia Tech as one of the leading institutions in origins-of-life research.
