In an article published in Physics Magazine, School of Physics Ph.D. student Jingcheng Zhou and Assistant Professor Chunhui (Rita) Du review efforts to optimize diamond-based quantum sensing. According to Zhou and Du, the approach used in two recent studies broadens the potential applications of nitrogen-vacancy center sensors for probing quantum phenomena, enabling measurements of nonlocal properties (such as spatial and temporal correlations) that are relevant to condensed-matter physics and materials science.

Community engagement has illustrated notable educational applications of the Life Detection Knowledge Base (LDKB). The webtool's utility as an educational resource for next generation mission planners and astrobiologists was demonstrated when Georgia Institute of Technology astrobiology course instructor Jennifer Glass, associate professor in the School of Earth and Atmospheric Sciences, adopted it for a class project across several semesters from 2022 to 2023. In her graduate course, Seminal Papers in Astrobiology, Glass assigned students a biogenic or abiotic stance on a seminal astrobiology case study, such as the debate on the oldest microfossils. Students constructed and iterated arguments and evidence on their chosen topics for inclusion into multiple LDKB entries. A second example of the tool’s success in education came from a collaboration with the Young Scientists Program internship through the Blue Marble Space Institute of Science. Through both efforts, students developed arguments and supporting evidence for inclusion in the LDKB, gaining useful skills in peer reviewing, scientific writing, and scientific debate.

Thursday’s meteor captivated many across the Southeast, but perhaps no one was quite as thrilled as the amateur meteorite chasers who track down bits of space rock and the astronomy researchers whose lifework is analyzing space activity.

Toshi Hirabayashi, a Georgia Tech associate professor who studies space operations, celestial mechanics, and planetary science, quickly began analyzing videos of the fireball Thursday “just for fun.”

Based on his rough calculations, the object was moving “definitely faster than 10 miles per second” or roughly 36,000 mph, he said.

While it’s fun to see smaller meteorites hit the Earth, it’s critical to prepare for when a larger meteor comes blazing in and does real damage. In 2013, a meteor the size of a house exploded 14 miles above Russia, Hirabayashi said.

“We are working so hard to monitor, as well as develop technologies to defend Earth,” he said.

Hirabayashi was also cited in articles published by FoxWeather and WSB TV.

In a video interview published by 11 Alive, School of Chemistry and Biochemistry faculty Mike Evans explains the science behind two classic summer traditions: fireworks and grilling.

Friday marks the official start of summer and with the changing of the seasons comes a significant shift in the weather pattern. After weeks of an unusually wet pattern, temperatures are expected to climb into the mid-90s throughout the coming week. 

This transition poses particular challenges for those unaccustomed to the high temperatures. Mike Sawka, an adjunct professor at Georgia Tech’s School of Biological Sciences who studies heat adaptation in athletes and workers, emphasized the importance of gradual acclimatization.

"You can do quite a bit in four days, but you basically adapt to what you [are] exposed to," Sawka explained. "We usually use a rule of thumb that after eight to 10 days, you're pretty well adapted to whatever you've been exposed to."

Sawka was cited in a similar story about acclimatization, published by 11 Alive on June 24.
