A "black hole tango," the imagery in the headline for this Science story, hints at the implications of the latest news coming from the Laser Interferometer Gravitational-Wave Observatory (LIGO). The international team of scientists, which includes Georgia Tech faculty and students, says it has recorded evidence of a third black hole collision and the gravitational waves it produced. "These black holes are not like two aligned tornadoes orbiting each other, but like two tilted tornadoes," says Laura Cadonati, School of Physics associate professor and LIGO deputy spokesperson, adding that the research may prompt new theories regarding how these massive collapsing stars pair up in the first place. The latest LIGO findings are also covered at Space.com and National Geographic.

More than a dozen Georgia Tech faculty members, students, and postdoctoral fellows are working with the large international research team that makes up the Laser Interferometer Gravitational-Wave Observatory (LIGO). This is the team that made its own splash in the science world in 2015 with the first detection of a gravitational wave signal, the result of a black hole collision 1.5 billion light years from Earth. Now LIGO announces that a third gravitational wave was observed and confirmed in January from even farther away: about 3 billion light years. Once again, Albert Einstein has been proven right, and once again the science media can't resist a story that features black holes acting mysteriously and ripples of space and time flying through the cosmos at lightspeed. In addition to this USA Today story, coverage includes the Washington Post, BBC News, Scientific American, The Verge and Phys.org, among others. School of Physics associate professor Laura Cadonati is LIGO's deputy spokesperson, and research scientist James Clark from the Center for Relativistic Astrophysics worked on the latest discovery.

The study found that despite a wide range of sizes in bodies and feces, most healthy mammals poop at the same rate. There is one telling behind-the-scenes detail: study co-author Patricia Yang says her team promised other graduate students sharing the lab not to bring their animal dropping samples from the Atlanta Zoo into the lab until after 5 p.m. because of the smell. Hu is also an adjunct associate professor in the School of Physics and an associate professor in the George W. Woodruff School of Mechanical Engineering. Yang is a Ph.D. student in the Woodruff School of Mechanical Engineering.

Research led by Georgia Tech physicist Itamar Kolvin has found that the presence of small imperfections or heterogeneities in materials can have a dual effect on their strength and resilience. While heterogeneities were historically believed to make materials stronger by creating an obstacle course for cracks, the new study shows that in some complex materials, heterogeneities can actually accelerate crack propagation and weaken the overall structure. The findings have implications for how engineers design and reinforce materials to optimize their toughness.
Atlanta Today 2026-02-27T00:00:00-05:00Assistant Professor Zhu-Xi Luo and Ph.D. student Yi-Lin Tsao from Georgia Institute of Technology's School of Physics have demonstrated a novel mechanism for stabilising physical phases vulnerable to topological defects. Their work addresses a fundamental problem in condensed matter physics: the destabilisation of phases like superfluids by thermally-induced defects such as anyons and vortices.
Quantum Zeitgeist 2026-02-25T00:00:00-05:00In an article published in Physics Magazine, School of Physics Ph.D. student Jingcheng Zhou and Assistant Professor Chunhui (Rita) Du review efforts to optimize diamond-based quantum sensing. According to Zhou and Du, the approach used in two recent studies broadens the potential applications of nitrogen-vacancy center sensors for probing quantum phenomena, enabling measurements of nonlocal properties (such as spatial and temporal correlations) that are relevant to condensed-matter physics and materials science.
Physics Magazine 2025-07-14T00:00:00-04:00Researchers at the Georgia Institute of Technology and India's National Center for Biological Sciences have found that yeast clusters, when grown beyond a certain size, spontaneously generate fluid flows powerful enough to ferry nutrients deep into their interior.
In the study, "Metabolically driven flows enable exponential growth in macroscopic multicellular yeast," published in Science Advances, the research team — which included Georgia Tech Ph.D. scholar Emma Bingham, Research Scientist G. Ozan Bozdag, Associate Professor William C. Ratcliff, and Associate Professor Peter Yunker — used experimental evolution to determine whether non-genetic physical processes can enable nutrient transport in multicellular yeast lacking evolved transport adaptations.

Phys.org 2025-06-24T00:00:00-04:00Other planets, dwarf planets and moons in our solar system have seasonal cycles — and they can look wildly different from the ones we experience on Earth, experts told Live Science.
To understand how other planets have seasons, we can look at what drives seasonal changes on our planet. "The Earth has its four seasons because of the spin axis tilt," Gongjie Li, associate professor in the School of Physics, told Live Science. This means that our planet rotates at a slight angle of around 23.5 degrees.
"On Earth, we're very lucky, this spin axis is quite stable," Li said. Due to this, we've had relatively stable seasonal cycles that have persisted for millennia, although the broader climate sometimes shifts as the entire orbit of Earth drifts further or closer from the sun.
Such stability has likely helped life as we know it develop here, Li said. Scientists like her are now studying planetary conditions and seasonal changes on exoplanets to see whether life could exist in faroff worlds. For now, it seems as though the mild seasonal changes and stable spin tilts on Earth are unique.
Live Science 2025-05-05T00:00:00-04:00Biofilms have emergent properties: traits that appear only when a system of individual items interacts. It was this emergence that attracted School of Physics Associate Professor Peter Yunker to the microbial structures. Trained in soft matter physics — the study of materials that can be structurally altered — he is interested in understanding how the interactions between individual bacteria result in the higher-order structure of a biofilm
Recently, in his lab at the Georgia Institute of Technology, Yunker and his team created detailed topographical maps of the three-dimensional surface of a growing biofilm. These measurements allowed them to study how a biofilm’s shape emerges from millions of infinitesimal interactions among component bacteria and their environment. In 2024 in Nature Physics, they described the biophysical laws that control the complex aggregation of bacterial cells.
The work is important, Yunker said, not only because it can help explain the staggering diversity of one of the planet’s most common life forms, but also because it may evoke life’s first, hesitant steps toward multicellularity.
