Mars is still in NASA's sights for a possible future manned mission, and a new study finds that when those astronauts land, they may have limitless access to water. The study uses new Mars Reconnaissance Orbiter data and images to show a 100-meter-thick ice sheet that's just under the planet's surface — in some cases, merely a meter beneath the Martian sands. This Quartz story on the findings highlights how the ice sheets could hold a record of Mars' climate. James Wray, an associate professor in the School of Earth and Atmospheric Sciences, contributed to the study, as did Lujendra Ojha, a former Tech researcher who led the 2015 study offering evidence of flowing water on Mars. Ojha is now at Johns Hopkins University.

Why did Remington Poulin decide to make a living in chemistry while still in high school? "It's a whole other language of things you can't see," he tells his hometown newspaper. That heightened sense of scientific curiosity led him from Maryland to Georgia Tech, where he received his Ph.D. last year from the School of Chemistry and Biochemistry under the supervision of Julia Kubanek, a professor of chemistry and biochemistry and of biological sciences. Poulin, now conducting postdoctoral research at the Max Planck Institute for Chemical Ecology in Germany, was the lead author on a new Tech study that for the first time identifies the chemicals in blue crab urine that scare off their prey. Poulin explains how he collected that crab urine and details how the study's findings could lead to better management of crab and oyster farms.

Georgia Public Broadcasting radio host Celeste Headlee replays her 2015 interview with Patricia Yang, a doctoral student and co-winner of an Ig Nobel Award, an honor presented by Improbable Research given to science projects that "make you laugh, then make you think." Yang's award was for a study on animal urination, which involved monitoring and recording the bladder-emptying habits of 32 different mammals at Zoo Atlanta. Yang worked on the study with David Hu, an associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Biological Sciences, with an adjunct appointment in the School of Physics.

Should doctors who are increasingly concerned about antibiotic resistance hold off on using them to treat mild infections? Should they use alternative treatments instead, and save the stronger medicine for more serious infections? Those questions were raised in a recent essay published in PLOS Biology by Kristofer Wollein Waldetoft and Sam Brown, both with the School of Biological Sciences. In this audio report, Heather Goldstone of WCAI's Living Lab Radio interviews Waldetoft, a postdoctoral researcher. Brown is an associate professor.

Lew Lefton routinely straddles the worlds of polynomials and punchlines. Lefton, a senior academic professional in the School of Mathematics, and assistant dean of information technology for the College of Sciences, has also been a standup/improvisational comedian for 30 years. The Story Collider, a content platform that highlights the human side of science via live shows around the U.S. and a weekly podcast, taped Lefton's standup performance at Atlanta's Highland Inn last October. Lefton is also assistant vice president for research cyberinfrastructure in the office of Tech's Executive Vice President for Research.

Count Kim Cobb among those scientists who have become distraught about the rapidly deteriorating health of coral reefs worldwide due to climate change. Cobb, a professor in the School of Earth and Atmospheric Sciences with expertise in coral reefs, has seen the damage of coral bleaching up close during dives to observe ecosystems near Hawaii in connection with her research. In this story, Cobb responds to a recent study on the frequency of extreme bleaching events. Cobb is not affiliated with the study.

A Georgia Tech honors graduate who was both a Rhodes and Truman Scholar may have a chance to impact the purchase of new technologies for the Air Force. William Roper, currently founding director of the Pentagon's Strategic Capabilities Office, is President Trump's nominee to be assistant secretary of the Air Force for acquisitions. Roper, who has argued that the Defense Department should use more commercial software, graduated summa cum laude with a B.S. from the School of Physics in 2001. He earned his M.S. in physics from Tech in 2002, also summa cum laude. Roper has a Ph.D. in mathematics from the University of Oxford.

It seemed nature really had a grudge against North America in 2017, what with all the hurricanes, wildfires, and earthquakes. At the same time, the rest of the world caught a break of sorts from its usual yearly quota of disasters. This review of the economic toll of last year's global weather and seismic-related disasters includes comments from Kim Cobb, professor in the School of Earth and Atmospheric Sciences.

This Medical Xpress item is a reprint of a Georgia Tech news release on the recent thought paper published in PLOS Biology by Sam Brown and Kristofer Wollein Waldetoft. They suggest that physicians should come up with alternatives for treating smaller, non-life-threatening bacterial infections in an effort to save antibiotic effectiveness for more serious infections. Brown is an associate professor in the School of Biological Sciences, and Waldetoft is a postdoctoral research assistant in Brown's lab.

The "Star Wars" theme is an ode to triumph, and there's no better way for musician Jason Barnes to show off his new prosthetic right hand than playing the song on a piano. Barnes, who lost the hand in 2012, received his prosthesis from researchers at Tech's Center for Music Technology. The prosthesis allows for greater control of individual fingers. Associate Professor Minoru Shinohara and lecturer Chris Fink were part of the design team; both are with the School of Biological Sciences.
