Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice called clathrates trap methane gas, preventing it from escaping and bubbling up into the atmosphere. Until now, the biological process behind how methane gas remains stable under the sea has been almost completely unknown. In a breakthrough study, a cross-disciplinary team of Georgia Tech researchers discovered a previously unknown class of bacterial proteins that play a crucial role in the formation and stability of methane clathrates.
A new theory allows researchers to create easy-to-solve mathematical models using cables, a previously challenging mathematical problem — offering key insights into the behavior of deformable solids, with applications spanning from engineering and biology to nanotechnology.
Atlanta Science Festival (ASF) presented by Delta Air Lines, the city’s ultimate celebration of all things science and one of the largest of its kind in the country, returns March 9-23. All ages can experience more than 100 interactive and educational events. The Exploration Expo, a giant science bash in Piedmont Park, returns as the grand finale of the Festival. The Festival will kickstart with the Science and Engineering Day at Georgia Tech.
Scientists have been trying to build snakelike, limbless robots for decades. These robots could come in handy in search-and-rescue situations, where they could navigate collapsed buildings to find and assist survivors. Georgia Tech researchers Tianyu Wang, a robotics Ph.D.
Are our bodies solid or liquid? This question begins the exploration of a study led by Zeb Rocklin, an assistant professor in the School of Physics at Georgia Tech, that blurs the lines between solid and liquid states by examining materials that exhibit properties of both.
Researchers at the Georgia Institute of Technology, working with a team from China’s Tianjin University, claim to have developed the first functional semiconductor from graphene, a single-layer carbon structure renowned for its robust bonds.
When Intel co-founder Gordon Moore made the observation that came to be known as Moore's Law, he projected that transistor density would continue doubling in density every two years... for another ten years. Working with Tianjin University in China, though, researchers at Georgia Tech have made a breakthrough in this department by growing graphene on doped silicon carbide wafers, introducing impurities into the graphene that give it a usable band gap, enabling the researchers to create graphene transistors the size of a carbon atom.
Odd things can happen when a wave meets a boundary. In the ocean, tsunami waves that are hardly noticeable in deep water can become quite large at the continental shelf and shore, as the waves slow and their mass moves upward.
The way muscles work changes when a person goes from slow, even movements to rapid, unsteady movements. Anyone who’s pulled a muscle after a sudden motion knows that. What we don’t know is exactly how muscle function changes when dynamic movement is introduced.
Brandon Pries is a graduate student in the School of Physics who researches computational astrophysics with Professor John Wise, using machine learning to study the formation and evolution of supermassive black holes in the early universe. Pries has also done extensive research with the NSF IceCube Collaboration. Pries recently shared a deep dive on neutrinos with astrobites, a daily literature journal (an "astro-ph reader's digest") supported by the AAS.
