3-legged lizards can thrive against all odds, challenging assumptions about how evolution works in the wild
James T. Stroud, assistant professor in the School of Biological Sciences, coauthored an article published in The Conversation detailing research which documents exceptional cases of lizards — survivors of limb damage or loss — that defy expectations about how natural selection works.

Finding friends at Fossil Fridays
Last Friday, the Spatial Ecology and Paleontology Lab (SEPL), led by School of Biological Sciences Associate Professor Jenny McGuire, hosted its weekly Fossil Friday event. This hands-on outreach program invites participants to uncover ancient history, explore real fossils, and learn about the discoveries made by scientists beneath the approximately 80-foot drop of Natural Trap Cave in Wyoming.
The goal of Fossil Friday is straightforward: to build a community centered on science outreach and enable people to interact directly with fossils. The event is open to students, faculty, and Atlanta locals alike, offering a relaxed space to learn, discover, and have fun.

Will we know artificial general intelligence when we see it?
We may never agree on what AGI or “humanlike” AI means, or what suffices to prove it. As AI advances, machines will still make mistakes, and people will point to these and say the AIs aren’t really intelligent. Anna Ivanova, an assistant professor in the School of Psychology at Georgia Tech, was on a panel recently, and the moderator asked about AGI timelines. “We had one person saying that it might never happen,” Ivanova told me, “and one person saying that it already happened.” So the term “AGI” may be convenient shorthand to express an aim—or a fear—but its practical use may be limited. In most cases, it should come with an asterisk, and a benchmark.

Tracking Year-to-Year Changes in North Atlantic Ocean Circulation
In a new study published in Geophysical Research Letters, Georgia Tech physical oceanographer Susan Lozier and researcher Yao Fu shed light on the shifting dynamics of the Atlantic Meridional Overturning Circulation (AMOC). Their findings, produced in collaboration with an international team of scientists, reveal shifts across surface and deep ocean currents, with implications for climate prediction and ocean heat transport. This research underscores the importance of sustained observational efforts in understanding long-term ocean variability.
