The sheer speed of temperature increases in the climate crisis era, combined with the fragmentation of landscapes by human activity, is making it harder for trees and other plants to follow their preferred climate conditions. These changes are disrupting a millennia-old process of plant migration, and it could pose a major challenge to global efforts to protect wildlife and reforest land to fight climate change. A study published Feb. 6 by Georgia Tech researchers found that 75% of the dominant plant groups in North America, including trees like pines and oaks, have migrated across the region over the last 18,000 years to track the movement of their ideal growing conditions. That plant migration will be harder to pull off over the coming decades, according to Jenny McGuire, assistant professor in the School of Earth and Atmospheric Sciences and the School of Biological Sciences, and a co-author of the study. “There’s so many barriers and filters to plant movement now. That could prevent them from shifting in some places,” she says.

Marshall Shepard, Georgia Athletic Association Distinguished Professor and director of the University of Georgia's Atmospheric Sciences Program, wrote this article on the experience of sharing a Ferst Center for the Arts stage February 8 with Vice President Kamala Harris and oceanographer Isaiah Bolden, assistant professor in the School of Earth and Atmospheric Sciences. The topic was climate change from an economic and racial justice viewpoint, but Shepard writes about the impact of the event happening during Black History Month. While Shepard writes that more work is needed diversifying the atmospheric and ocean sciences, "this moment in Black History cannot be overlooked. In February 2023 two black scholars and a black woman, who just happens to be the Vice President of the United States, sat on a stage discussing climate, environmental policy, and why it matters to all communities, but particularly those with people that look like them." (The climate conversation at Georgia Tech was also covered by the Atlanta Journal-Constitution, Fox5 Atlanta, Georgia Public Broadcasting, E&E News, and the Technique. A White House transcript of the event is found here.)

Expensive military hardware, like a new tank undergoes rigorous testing before heading to the battlefield. A startup called Istari, backed by Eric Schmidt, the former CEO of Google and chair of Alphabet, reckons some of that work can be done more effectively in the metaverse. Ishtari uses machine learning to virtually assemble and test war machines from computer models of individual components, such as the chassis and engines, that are usually marooned on separate digital drawing boards. Will Roper, B.S. and M.S. PHYS, and a former assistant secretary of the Air Force, is founder and CEO of Ishtari.

Beginning this upcoming summer term, Georgia Tech’s School of Earth & Atmospheric Sciences (EAS) will offer three new Bachelor of Science degrees. These undergraduate opportunities will expand the breadth of the EAS program while simultaneously allowing students in the program to develop a more specialized plan of study in a field that aligns with their interests. The University System of Georgia (USG) has approved two new degrees within the school: Atmospheric and Ocean Sciences (AOS) and Solid Earth and Planetary Sciences (SEP). They also approved a new bachelor’s degree in Environmental Sciences (ENVS) that will be an interdisciplinary degree between EAS and the School of Biological Sciences (BIOS).

Just like fashioning decorative shapes and figures using the Japanese art of folding paper, tracing when and where origami originated is complicated. But what cannot be disputed is its incredible influence in modern engineering. While styles of origami can be incredibly diverse, the art is rooted in mathematical principles that make it applicable to science and industry. This story in E&T mentions scientists at Georgia Tech exploring origami, kirigami (where paper is cut as well as folded) and specific folding techniques for building everything from furniture to bridges. One of those scientists is D. Zeb Rocklin, assistant professor in the School of Physics. 

Astrobites, a daily astrophysical literature journal written by graduate students in astronomy since 2010, features a guest column written by two Ph.D. students extolling the virtues of community college. One of the authors is School of Physics alumna Kiersten Boley, B.S PHYS 2019, now seeking a Ph.D. in astronomy from Ohio State University. Boley writes that she didn't want to become a physicist until she attended community college, where her professor in introductory physics "sparked my love of science." Boley credits that with helping her thrive at Georgia Tech. 

Lithos Carbon, a US-based startup transforming farmland into carbon removal centers using the power of volcanic rocks, aims to capture 10,000 tons of carbon this year. Lithos accelerates mineral weathering by spreading basalt on croplands to increase dissolved inorganic carbon with eventual storage as ocean carbonates. Its technology uses novel soil models and machine learning to maximize carbon dioxide (CO₂) removal while boosting crop growth. Chris Reinhard, associate professor in the School of Earth and Atmospheric Sciences, is one of the three co-founders of Lithos Carbon. 

Want to touch a human brain, learn the mechanics behind animation or attend the “nerdiest fashion show of the year”? At the Atlanta Science Festival, you can. The Atlanta Science Festival (ASF) is back for its 10th edition from March 10 to 25. ASF is an annual celebration of learning, science and STEM career opportunities around the Atlanta region. This year, the line-up features 150 events across 80 locations in the city and metro area. Faculty members, staff, and students from the College of Sciences will be taking part in the two weeks of activities. (Schedule of events and other information is available here.)

Florida State University climate scientists and others were recently granted $3.2 million from the U.S. Department of Energy to investigate carbon storage in the peatlands environment. Peatlands can be found across the globe, covering almost every continent. The largest area of peatlands can be found towards the Northern and Southern hemispheres and closest to the equator. In Florida, the greatest example of a peatland environment is the Everglades. FSU will work with Georgia Tech researchers on the DOE grant, including Joel Kostka, professor in the School of Biological Sciences and the School of Earth and Atmospheric Sciences. 

Matt Baker, professor in the School of Mathematics and associate dean for Faculty Development in the College of Sciences, is on the cover of the current issue of Math Horizons, a journal of the Mathematical Association of America (MAA). Baker, who is also a two-time winner of the Greater Atlanta Magician of the Year Award, is profiled about his love of math and magic, and his use of magic in researching and demonstrating math theorems. "I thought math and magic were two separate things," Baker said. "Until I was really shown the connection, I didn’t try too hard to think about creating my own magic tricks based on math principles, and now I’m kind of obsessed with that and spend a lot of time doing it."
