For most of the industrial era, spreading crushed limestone across farmland has been treated as a carbon problem. The rock contains carbon; it ends up in contact with air and water, and by the most conservative accounting conventions, carbon is assumed to escape as carbon dioxide. Regulators and major climate assessments have baked that assumption into their default rules for decades.

A study published in Nature now argues that the opposite is true and that the error came from asking the wrong question. Across more than 120 years of records from the Mississippi River Basin, the researchers, including study co-author Chris Reinhard, conclude that agricultural liming has removed somewhere between 300 and 400 million metric tons of carbon dioxide from the atmosphere since 1900.

Oceanographer Lily Dove has worked with marine mammals and robots to better understand climate change in Antarctica. In an interview published by Science News Explores, she discusses her experiences and shares advice for students interested in careers in science.

Coral reefs are under pressure. The seas they live in are getting ever warmer and more acidic, taking them out of coral’s comfort zone. Pollution is encouraging algal blooms, which stifle their growth. And overfishing is wiping out many species that they depend on for protection.

The over-fished species which have drawn most attention are those that feed on the algae or hunt others which have a penchant for consuming coral. However, Cody Clements and Mark Hay of the Georgia Institute of Technology wish to add what might seem an unlikely candidate to the list: sea cucumbers.

In an article published by The Conversation, Shiladitya Banerjee, associate professor in the School of Physics, discusses new research suggesting that single bacterial cells exhibit learning-like behavior in changing environments.

A new study by Professor Francesca Storici’s research team along with collaborators at multiple institutions has uncovered an unexpected feature of human DNA linked to gene activity and the physical organization of DNA. The findings, published in Cell, could change how scientists think about DNA organization, transcription, and genome function.

If you dropped the exact same pulse of food onto two identical bacteria, you'd expect the exact same response. That's not what happened. In a study published in PRX Life in May 2026, researchers at Carnegie Mellon University and Georgia Tech found that E. coli exposed to unstable, feast-and-famine conditions adapted to new food far faster than bacteria pulled from a stable environment, even when the immediate conditions in front of them were identical.

You may think that one cell has no place to keep things such as memories. Scientists, including Josiah Kratz, a postdoctoral fellow in Georgia Tech’s School of Physics, observed tens of thousands of individual E. coli bacteria through a special microfluidic apparatus and found that the cause was ribosomes, the components of the cell responsible for building proteins and determining the growth rate.

Karl Lang, assistant professor in the School of Earth and Atmospheric Sciences at Georgia Tech, joined FOX Weather to discuss what is driving the Nepal disaster, the risks posed by glacial lake outburst floods, and the long-term challenges communities face.

After 10 days in isolation, a group of Georgia Tech students will be returning from Arkansas having completed their first simulated Mars mission. Southeast Analog is a program run by students at Georgia Tech interested in spaceflight. 

The SEA-1 Thalassa mission included six "astronauts" on a simulated Mars habitat in Arkansas and 30 crew in mission control on campus. Students in the Southeast Analog program worked in three shifts around the clock to do astronaut training, spaceflight operations, and research.

Dangerously high heat levels forced at least one metro Atlanta school district to pull students inside Monday as heat index values head toward triple digits this week. 

Georgia Tech biology adjunct professor Mike Sawka explained that extreme heat creates severe cardiovascular strain during exercise. "The main problem with heat stress is it puts stress on the cardiovascular system," Sawka said. "The blood flow that would normally go to the muscles has to be shared by the skin. So as you exercise, you're cheating the blood flow from the heart called your cardiac output". 

Sawka noted that extended exertion in hot weather puts the human body into overdrive, triggering a progression of severe health risks. "That can lead to either heat exhaustion, heat injury, or heat stroke, which is a continuum of serious heat illnesses, with heat stroke being the most severe," Sawka said. 

Instructors say open-ended student comments are the most valuable kind of course feedback. But reading through hundreds or thousands of such comments is time-consuming, so the insights often go unused. Georgia Tech researchers have developed an AI platform that sorts written feedback into themes, with student comments aggregated. Next steps include deploying the platform as a secure cloud service; connecting it to campus systems that manage teaching and learning; and running a pilot at Georgia Tech. • Georgia Tech lab of Gregory Mayer

In an article published by The Conversation, Professor Joseph Montoya, Postdoctoral Fellow Xing Zhou, and their collaborator discuss sargassum blooms and their impact on the Caribbean and Gulf coasts and the coasts of the tropical Atlantic. According to their research, the vast mats of smelly, brown seaweed affecting these areas may have entered a "self-sustaining cycle, effectively feeding their own expansion."

Researchers in the School of Physics, working with King Fahd University of Petroleum and Minerals, have found that standard methods for identifying chirality in topological phases fail when applied to mixed quantum states. The study reveals that established diagnostics, including bulk-boundary correspondence and the modular commutator, are unreliable in these complex systems. Consequently, the research presents two new measures, based on relative entropy, to accurately diagnose chirality and determine the chiral central charge in decohered topological phases, indicating a need for a new set of tools when investigating mixed-state topology.
