The School of Biological Sciences gathered on April 26th to celebrate its 2017 graduates.
What can microorganisms teach us about climate change? Plenty, because microbes respond, adapt, and evolve faster than other organisms. Scientists can discover how microorganisms will change because of global warming more quickly than is possible for complex organisms. Understanding how microbes respond to climate change will help predict its effects on other forms of life, including humans.
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.
