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.

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.
