This STEM outreach project uses an 11-inch Celestron telescope, also known as the Aloha Telescope, to provide students in grades K-12 the ability to view live images from their classrooms and remotely control the telescope via an internet connection. The idea for this project originated from Dr. James Sowell, an astronomer and observatory director at the School of Physics.

<![CDATA[Adirondack Park’s role in animal migration]]> 36583 Recent studies show nearly half of the world’s species are on the move because of the changing climate and habitat disruption. Apart from slowing fossil fuel production and prioritizing carbon storage, a direct solution for species inching north as temperatures rise is improving climate connectivity, a term likely coined by researchers from the Georgia Institute of Technology in a 2016 study. The idea builds on the established science of wildlife corridors and land conservation that supports the migration of animals. School of Earth and Atmospheric Sciences Assistant Professor Jenny McGuire, who worked on the study, said this kind of movement differs from traditional migration patterns. Instead of departing annually and returning, species are permanently moving to areas they’re finding more hospitable. “They’re moving in such a way that they’re tracking the climates they’re suited to live in or able to live in, and then staying in those places,” McGuire said.

But some scientists feel that improvements are needed before we can rely on AI to describe studies accurately. Will Ratcliff, an associate professor at the School of Biological Sciences, argues that no tool can produce better text than can professional writers. Although researchers have different writing abilities, he invariably prefers reading scientific material produced by study authors over those generated by AI. “I like to see what the authors wrote. They put craft into it, and I find their abstract to be more informative,” he says.

To learn more, researchers — including School of Biological Sciences and School of Earth and Atmospheric Sciences Professor Joel Kostka — leveraged the SPRUCE experiment, where scientists can combine air and peat warming in a whole-ecosystem warming treatment. Peatlands build carbon stocks over centuries, but rising temperatures and atmospheric carbon dioxide concentrations rapidly changed the equilibrium at SPRUCE within a 4-year timescale, highlighting the vulnerability of these carbon-rich ecosystems to global climate change.

<![CDATA[‘Living Fossil’ Lizards Are Constantly Evolving — You Just Can’t See It]]> 35575 Scientists have long wondered how some organisms seem to change very little, even over eons, despite the pressures of natural selection. The prevailing hypothesis for this “stasis paradox” has been that natural selection keeps some species unchanged by selecting for moderate or average traits (so-called stabilizing selection) rather than selecting for more extreme traits that would cause a species to change (directional selection). But a study published in the Proceedings of the National Academy of Sciences USA contradicts this idea, showing that evolution constantly favors different traits in seemingly unchanging animals that improve short-term survival. In the long term, though, “all that evolution cancels out and leads to no change,” says the study's lead author, James Stroud, a biologist at the Georgia Institute of Technology.

<![CDATA[Earth isn’t the only planet with seasons, but they can look wildly different on other worlds]]> 34434 Spring, summer, fall and winter – the seasons on Earth change every few months, around the same time every year. It’s easy to take this cycle for granted here on Earth, but not every planet has a regular change in seasons. So why does Earth have regular seasons when other planets don’t? Gongjie Li, assistant professor in the School of Physics, explains about axial tilts of planets, which have big implications for everything from seasons to glacier cycles, since that tilt can determine just how much sun a planet will get. The magnitude of that tilt can even determine whether a planet is habitable to life. (This article by Li was also reprinted in IFL Science, Qrius, The Good Men Project, and the Longmont (Colorado) Leader.

However, a mass extinction event near the end of this era has long been the subject of debate. Some scientists argue the Late Devonian mass extinction was caused by large-scale volcanic eruptions, causing global cooling. Others argue a mass deoxygenation event caused by the expansion of land plants was to blame. 
recently published study in the journal Communications Earth and Environment now posits that both factors played a role — and draws attention to the environmental tipping points the planet faces today.

<![CDATA[‘Living Fossil’ Lizards Are Constantly Evolving—You Just Can’t See It]]> 34434 Evolution can perform spectacular makeovers: today's airborne songbirds descended from the wingless, earthbound dinosaurs that roamed millions of years ago, for example. But some organisms seem to change very little, even over eons. Scientists have long wondered how these species withstand the pressures of natural selection. The prevailing hypothesis for this “stasis paradox” has been that natural selection keeps some species unchanged by selecting for moderate or average traits (so-called stabilizing selection) rather than selecting for more extreme traits that would cause a species to change (directional selection). But a study published in the Proceedings of the National Academy of Sciences USA contradicts this idea, showing that evolution constantly favors different traits in seemingly unchanging animals that improve short-term survival. In the long term, though, “all that evolution cancels out and leads to no change,” says the study's lead author, James Stroud, assistant professor and Elizabeth Smithgall-Watts Endowed Faculty in the School of Biological Sciences

This study's researchers pair an atmospheric retrieval tool to a thermodynamics model to assess the detectability of chemical disequilibrium signatures of Earth-like exoplanets, focusing on the Proterozoic eon when the atmospheric abundances of oxygen–methane disequilibrium pairs may have been relatively high. One of the study's authors is Chris Reinhard, associate professor in the School of Earth and Atmospheric Sciences

<![CDATA[Light Happy Yeast May Change Our Approach to Biofuels]]> 34434 Yeast is maybe the best-understood microorganism in the world. Humans have leveraged yeasts' biochemical abilities to produce bread, alcohol, and fermented milk products since the dawn of civilization. Yeasts are also one of the most common organism “models” in biology laboratories. And important bio-factories for plenty of medicines and useful biomolecules. Still, yeasts need to be fed with sugar or other compounds to stay alive. At least, that was true until Anthony Burnetti, a research scientist working in the lab of William Ratcliff’s, associate professor in the School of Biological Sciences, managed to make yeast able to harvest the energy of light. The story highlights the potential impact of the research on biofuel production.

A significant milestone in this endeavor has been achieved by a team of researchers at Georgia Tech, who have successfully engineered the world's first functional semiconductor using graphene.

The study of these celestial ballets has been the focus of astrophysicist Gongjie Li, assistant professor in the School of Physics. Funded by NASA, Li’s research delves into the reasons behind seasonal patterns, centering on the effects of a planet’s axial tilt or obliquity. Earth has an axis tilted about 23 degrees from vertical, a feature that triggers the varying intensity of sunlight across different hemispheres, resulting in changing seasons. Li articulates that planets ideally aligned axially with their orbit around the sun, assuming a circular orbit, wouldn’t bear witness to seasons due to a constant influx of sunlight.

Here's why]]> 34434 Alien hunters should search for technological life on planets that possess a high oxygen abundance in their atmospheres, according to new research that aims to hone the search for technosignatures from extraterrestrial civilizations. The study from scientists at the University of Roma Tor Vergata in Italy and the University of Rochester in the U.S. argues that a planet's atmosphere needs to contain at least 18% oxygen to facilitate a technological civilization. The reason for this, they say, is a simple one: oxygen is needed for fire. This story cites another study detailing a future oxygen-related challenge for the Earth — as the sun ages and brightens in a billion years to produce more heat that warms our planet in turn, Earth's atmosphere will become deoxygenated, with oxygen levels dropping below 10 percent.

<![CDATA[Evolution: Fast or Slow? Lizards Help Resolve a Paradox.]]> 34434 James Stroud, assistant professor in the School of Biological Sciences, had a problem. The evolutionary biologist had spent several years studying lizards on a small island in Miami. These Anolis lizards had looked the same for millennia; they had apparently evolved very little in all that time. Logic told Stroud that if evolution had favored the same traits over millions of years, then he should expect to see little to no change over a single generation. Except that’s not what he found. Instead of stability, Stroud saw variability. One season, shorter-legged anoles survived better than the others. The next season, those with larger heads might have an advantage. This story builds on Stroud's recent study published in the Proceedings of the National Academy of Sciences.

Instead of stability, Stroud saw variability. One season, shorter-legged anoles survived better than the others. The next season, those with larger heads might have an advantage. This story builds on Stroud's recent study published in the Proceedings of the National Academy of Sciences.

<![CDATA[Florida's Frozen Iguana Phenomenon]]> 34434 James Stroud, assistant professor in the School of Biological Sciences, joined Fox Weather to talk about the "falling iguana alerts" now issued by the National Weather Service in Miami when temperatures dip unseasonably lower during the winter, causing the large lizards to freeze and fall out of Florida's trees. Stroud, an evolutionary ecologist, spoke of his lab's studies to find out whether iguanas are adapting to colder temperatures brought on by climate change, or whether genetic factors are involved. Iguanas, normally found in hotter Central and South American climates, are considered an invasive species for Florida.

<![CDATA[Lizards, fish and other species are evolving with climate change, but not fast enough]]> 34434 Climate change is threatening the survival of plants and animals around the globe as temperatures rise and habitats change. Some species have been able to meet the challenge with rapid evolutionary adaptation and other changes in behavior or physiology. Dark-colored dragonflies are getting paler in order to reduce the amount of heat they absorb from the sun. Mustard plants are flowering earlier to take advantage of earlier snowmelt. Lizards are becoming more cold-tolerant to handle the extreme variability of our new climate. However, scientific studies show that climate change is occurring much faster than species are changing. James Stroud, assistant professor in the School of Biological Sciences, co-authored this article. (This article was also covered at The Good Men ProjectBeaumont EnterpriseYahoo!

<![CDATA[Surge in extreme forest fires fuels global emissions]]> 34434 Global forest fires emitted 33.9 billion tons of carbon dioxide (CO2) between 2001 and 2022, according to a report by the Chinese Academy of Sciences (CAS). This makes the CO2 emissions generated by forest fires each year higher than those from burning fossil fuels in Japan — the world’s sixth-largest CO2 emitter. Driving the emissions spike was the growing frequency of “extreme forest-fire events”. Yuhang Wang, professor in the School of Earth and Atmospheric Sciences, tells Nature the report complements his work, which “indicates a roughly 20 percent rise in global burnt area by the 2050s compared to the 2000s”.

<![CDATA[A robophysical model of spacetime dynamics]]> 34434 Systems consisting of spheres rolling on elastic membranes have been used to introduce a core conceptual idea of general relativity: how curvature guides the movement of matter. However, such schemes cannot accurately represent relativistic dynamics in the laboratory because of the dominance of dissipation and external gravitational fields.

The researchers' mapping and framework facilitate creation of a robophysical analog to a general relativistic system in the laboratory at low cost that can provide insights into active matter in deformable environments and robot exploration in complex landscapes. Researchers includes Hussain Gynai and Steven Tarr, graduate students; Emily Alicea-Muñoz, academic professional; Gongjie Li, assistant professor; and Daniel Goldman, Dunn Family Professor.

A new study led by the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, Japan, reveals a chemical pathway compatible with early Earth conditions and by which C6 aldonates could have acted as a source of pentoses without the need for enzymes. Their findings provide clues about primitive biochemistry and bring us closer to understanding the Origins of Life. Charles Liotta, Regents' Professor Emeritus in the School of Chemistry and Biochemistry with a joint appointment in the School of Chemical and Biomolecular Engineering, is a co-author of the study.

<![CDATA[To Study Radioactive Neptunium and Plutonium, Researchers Establish a Novel Chemistry]]> 34434 Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium. To study these elements, scientists have designed donor ligands — molecules that contribute electron density to metal centers. This allows scientists to stabilize these metals as they become more electron-poor. Accessing and studying the high oxidation states of uranium, neptunium, and plutonium complexes helps scientists understand their chemical reactivities — how easily they form new chemical compounds. These studies can shed light on how radioactive materials may behave in nuclear waste streams and waste storage. This study summary was written by Henry La Pierre, associate professor in the School of Chemistry and Biochemistry and Director of the National Nuclear Security Administration Transuranic Chemistry Center of Excellence.

While people in many industries were able to start working from home during the pandemic, recouping their travel time, nearly half of U.S. workers kept devoting a good chunk of their day — sometimes an hour or more — to being in transit. Pandemic-era commuting has widened several divides: between those who can work remotely and those who can’t, and between those who drive and those who use public transportation. The decrease in travel by those able to work remotely has changed the nature of commutes for everyone else — streamlining rush-hour traffic, for example, but making trains run less often. This examination of how commutes have changed over the last three years includes comments from Christopher Wiese, assistant professor in the School of Psychology.

Now, a team of evolutionary biologists in Switzerland has identified genetic mutations that enable some bacterial colonies to expand rapidly. The findings, recently reported in PLoS Biology, suggest that mutations in just a few key genes can have widespread impacts on gene expression as bacteria replicate and move into new territory. “It’s really creative work,” says evolutionary biologist William Ratcliff, Associate Professor and Co-Director of the Interdisciplinary Ph.D. in Quantitative Biosciences in the School of Biological Sciences, who was not involved in the study. “Understanding the way that [bacteria] might evolve in nature, the complex life cycles that they possess, and how they respond to different kinds of environments can be really hard.”

<![CDATA[Underwater robot updates understanding of ice shelf crevasses]]> 34434 More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell-led research based on first-of-its-kind exploration by an underwater robot. The remotely operated Icefin robot’s climb up and down a crevasse in the base of the Ross Ice Shelf produced the first 3D measurements of ocean conditions near where it meets the coastline, a critical juncture known as the grounding zone. The robotic survey revealed a new circulation pattern – a jet funneling water sideways through the crevasse – in addition to rising and sinking currents, and diverse ice formations shaped by shifting flows and temperatures. Included in the Cornell research team is Justin Lawrence, a visiting Ph.D. scholar from the School of Earth and Atmospheric Sciences

During this type of eclipse, the Moon is near its farthest point from Earth, so it does not completely cover the Sun. The Moon appears as a dark disk on top of a larger, bright sun. In Georgia, we will see a partial solar eclipse. James Sowell, principal academic professional in the School of Physics and director of the Georgia Tech Observatory, said over the three-hour event the sun will take on a different appearance. "For those of us in Atlanta, it’s a little more than 50 percent. So you’d have the disk of the sun, and part of it would be blocked out. So you would first see a little blocked out, and ultimately about 50 percent... The sun would be a crescent and then the moon would work its way out," Sowell said. If you want to view the eclipse, you must do so safely. You'll need special protection. Special solar-safe glasses can be purchased online, which are much, much stronger than a normal pair of sunglasses. (11Alive also spoke with Sowell on Oct. 12)

<![CDATA[Wing-flapping robot helps explain the evolution of insect flight]]> 34434 Some insects can flap their wings so rapidly that it’s impossible for instructions from their brains to entirely control the behaviour. Building tiny flapping robots has helped researchers shed light on how they evolved to do this. For some insects, including mosquitoes, their brain signals and flapping are out of sync. After the initial signal to contract, the insects’ muscles undergo additional contract-relax cycles before they even receive another impulse from the brain. This so-called “asynchronous” flight allows them to flap their wings at exceptionally high rates. Several researchers from Georgia Tech set out to study the evolutionary history of this form of flight. Those researchers include Simon Sponberg, Dunn Family Associate Professor in the School of Physics and the School of Biological Sciences; Brett Aiello, former postdoctoral scholar in Sponberg's Agile Systems Lab; Ethan Wold, Ph.D. scholar in the School of Biological Sciences and the Quantitative Biosciences Graduate Program; and Jeff Gau, Ph.D. scholar in the George W.

Building tiny flapping robots has helped researchers shed light on how they evolved to do this. For some insects, including mosquitoes, their brain signals and flapping are out of sync. After the initial signal to contract, the insects’ muscles undergo additional contract-relax cycles before they even receive another impulse from the brain. This so-called “asynchronous” flight allows them to flap their wings at exceptionally high rates. Several researchers from Georgia Tech set out to study the evolutionary history of this form of flight. Those researchers include Simon Sponberg, Dunn Family Associate Professor in the School of Physics and the School of Biological Sciences; Brett Aiello, former postdoctoral scholar in Sponberg's Agile Systems Lab; Ethan Wold, Ph.D. scholar in the School of Biological Sciences and the Quantitative Biosciences Graduate Program; and Jeff Gau, Ph.D. scholar in the George W. Woodruff School of Mechanical Engineering and the Interdisciplinary Bioengineering Graduate Program. (This research was also covered at India Education DiaryArsTechnicaUC San DiegoEarth.com and Phys.org.)

<![CDATA[How Baking Soda Actually Makes Your Fridge Smell Better]]> 34434 If you notice an odor when you open your refrigerator, it might be time for a deep clean. But even immaculate shelves and crystal clear crisper drawers won’t save your fridge from that not-so-fresh smell if you frequently fill it with fancy cheese and fragrant leftovers. For most people, the solution is a box of baking soda. It’s a housekeeping hack that has stood the test of time because it works. But contrary to the story we’ve all been sold, baking soda doesn’t make your fridge smell better by “absorbing” unpleasant food odors. In fact, according to Anthony Rojas, senior academic professional in the School of Chemistry and Biochemistry, the neutralization actually happens outside the box.

"Any earthquakes happening on these pre-existing faults are just kind of resettling and shuffling, maybe a little of disturbance because something has changed, but it's not the kind of ongoing tectonics like on the West Coast.”

<![CDATA[Researchers Discover New Method To Overcome Antimicrobial Resistance]]> 34434 The World Health Organization has identified antimicrobial resistance as a worldwide concern because most clinical antibiotics are no longer effective against certain pathogenic bacteria. Antibiotics work by targeting specific parts of a bacteria cell, such as the cell wall or its DNA. Bacteria can become resistant to antibiotics in a number of ways, including by developing efflux pumps — proteins that are located on the surface of the bacteria cell. When an antibiotic enters the cell, the efflux pump pumps it out of the cell before it can reach its target so that the antibiotic is never able to kill the bacteria. However, in a new study published in Nature Communications, scientists say they've found a new class of molecules that inhibit the efflux pump and make the antibiotic effective again. The researchers include Katie M. Kuo, Ph.D. scholar in the School of Chemistry and Biochemistry, and James C. Gumbart, professor in the School of Chemistry and Biochemistry with an adjunct appointment in the School of Physics

The field of enzymology came into its own in the 20th century. Technological advances in the hands of creative enzymologists led to an ever-growing understanding of how enzymes achieve enormous rate accelerations as well as the structural basis for substrate specificity and allosteric regulation. A session scheduled for the Discover BMB convention in San Antonio March 23-26 will feature Raquel Lieberman, Professor and Sepcic-Pfiel Chair in Chemistry in the School of Chemistry and Biochemistry, speaking on the topic, Enzymes for a Sustainable Future.

<![CDATA[Southern California Earthquake Was Unlikely Triggered by Hurricane Hilary]]> 34434 Southern California is no stranger to earthquakes, but tropical storms like Hilary are rare. It’s even rarer for a magnitude-5.1 earthquake near Ojai, Calif. to strike on the same Sunday afternoon (Aug. 20, 2023) that a tropical storm swept through Southern California. This uncommon confluence of events has sparked a heightened curiosity in the general public, including popular memes and the portmanteau “hurriquake.” But is there a physical connection between these events beyond mere coincidence in space and time? Zhigang Peng, professor in the School of Earth and Atmospheric Sciences, was part of a research team that studied available meteorological and seismic data to reveal that the quake near Ojai, Calif. was almost certainly not triggered by Hilary, which had been downgraded to a tropical storm at the time the earthquake struck.

<![CDATA[Mystery shell on Ocracoke beach]]> 34434 Lynn Ingram writes that she thought she'd found the state seashell of North Carolina, a Scotch bonnet, on one of the state's beaches. But she soon discovered that the shell was a species of sea snail that is only found in the Pacific Ocean. How did it end up in the Atlantic? Joseph Montoya, professor in the School of Biological Sciences who is also director of Georgia Tech's Ocean Science and Engineering program, says one possibility involves ballast tanks of oceangoing ships; sometimes these shells start as larvae living in plankton that may have been caught up in a ship's ballast water.

This story details recent research underway at Summit Station, located close to the apex of the Greenland ice sheet and one of the most remote scientific stations on Earth. One of two ice-coring projects at Summit Station involved Rachel Moore, a postdoctoral scholar in the School of Earth and Atmospheric Sciences. Moore will use the core samples to study bacteria and other latent biological entities once afloat in the atmosphere and now buried in the ice sheet. Her research will provide a window into the Earth’s environmental history and changing atmospheric patterns that goes back about six centuries.

<![CDATA[Physicists solve mysteries of microtubule movers]]> 34434 Researchers are exploring how active matter can be harnessed for tasks like designing new materials with tailored properties, understanding the behavior of biological organisms, and even developing new approaches to robotics and autonomous systems. But that’s only possible if scientists learn how the microscopic units making up active matter interact, and whether they can affect these interactions and thereby the collective properties of active matter on the macroscopic scale. School of Physics Professor Roman Grigoriev and his research colleagues have found a potential first step by developing a new model of active matter that generated new insight into the physics of the problem. They detail their methods and results in a new study published in Science Advances, “Physically informed data-driven modeling of active nematics.” Lead author of the study is graduate researcher Matthew Golden. Co-authors are graduate researcher Jyothishraj Nambisan and Alberto Fernandez-Nieves, professor in the Department of Condensed Matter Physics at the University of Barcelona and a former associate professor of Physics at Georgia Tech.

<![CDATA[New Proof Finds the ‘Ultimate Instability’ in a Solar System Model]]> 34434 For centuries, ever since Isaac Newton formulated his laws of motion and gravity, mathematicians and astronomers have grappled with the long-term stability of planetary orbits in the solar system. In the simplest model, which considers only the gravitational forces exerted by the sun, the planets follow their elliptical orbits like clockwork for eternity. But once you account for gravitational attraction between the planets themselves, everything gets more complicated. You can no longer explicitly calculate the planets’ positions and velocities over long periods of time, and must instead ask qualitative questions about how they might behave. Might the effects of the planets’ mutual attraction accumulate and break the clockwork? Now, in three papers that together exceed 150 pages, a trio of mathematicians have proved for the first time that instability inevitably arises in a model of planets orbiting a sun. Rafael de la Llave, a professor in the School of Mathematics, didn't work on the research but is quoted in the article.

<![CDATA[Researchers discover algorithm to create shapes that roll down pre-determined paths]]> 34434 Researchers have developed a method to construct solid objects that roll down pre-determined paths, which they reckon could have applications in quantum mechanics and medicine. To get a ball of malleable clay to roll down a simple path, you can force it down a specific path once, squashing it as you go. Take it to the top again, restart it from the initial starting point on the ball's surface, and it will roll down the same path. The researchers took this principle to develop an algorithm that could produce a shape capable of following almost any pre-determined path, even making the weird-shaped solids out of 3D-printed plastic and solid ball-bearings (for weight) to prove the point. Elisabetta Matsumoto, assistant professor in the School of Physics, co-wrote an accompanying article to the study saying "future work developing for more precise mathematical understanding of the issue would help to connect this work to applications, as well as to open up more purely mathematical veins of research."

The researchers took this principle to develop an algorithm that could produce a shape capable of following almost any pre-determined path, even making the weird-shaped solids out of 3D-printed plastic and solid ball-bearings (for weight) to prove the point. Elisabetta Matsumoto, assistant professor in the School of Physics, co-wrote an accompanying article to the study saying "future work developing for more precise mathematical understanding of the issue would help to connect this work to applications, as well as to open up more purely mathematical veins of research."

<![CDATA[Fossils Are Tackling One of Conservation’s Toughest Questions]]> 34434 Fossils aren’t only useful for learning about the past. They can also suggest how plants and animals might respond to future events — most pressingly, climate change. For example, Jenny McGuire, assistant professor and conservation paleobiologist in the School of Earth and Atmospheric Sciences, and her colleagues studied fossilized pollen grains to see how 16 important plant taxa from North America responded to climate change over the past 18,000 years. Did the plants shift their ranges to follow their preferred climate, the researchers wondered, or did they stay put and make the best of things as the climate changed around them? Twelve of the 16 taxa changed their geographic distribution to maintain similar climate niches, the researchers found — even in periods when the climate was changing rapidly. (This story was first published in Knowable Magazine.)

<![CDATA[‘Folks in Alaska should take this seriously.’ Anchorage not safe from tsunamis, study finds]]> 34434 On a cold March evening in 1964, a colossal earthquake struck off the coast of Alaska. At magnitude 9.2, it was the largest earthquake ever recorded in North America, and it triggered massive tsunamis that killed more than 120 people and leveled communities. But no wave reached Anchorage, the state’s biggest city. Many concluded that nearby geography makes the city immune to tsunamis. A new study published this week by the Alaska Division of Geological and Geophysical Surveys (DGGS), however, finds Anchorage simply got lucky in 1964—and might not the next time an earthquake strikes the seismically active region. Hermann Fritz, professor in the School of Civil and Environmental Engineering, Ocean Science and Engineering, and the School of Earth and Atmospheric Sciences, did not work on the study but is quoted in this article.

<![CDATA[Warming Could Push the Atlantic Past a ‘Tipping Point’ This Century]]> 34434 Could the system of ocean currents that regulates the climate for a swath of the planet — currents known as the Atlantic Meridional Overturning Circulation (AMOC) — collapse sooner than expected? New research, published in the journal Nature Communications, show that a sharp weakening of the currents, or even a shutdown, could be upon us by century’s end. In interviews, several researchers who study the overturning applauded the new analysis for using a novel approach to predict when we might cross a tipping point. But they voiced reservations about some of its methods, and said more work was still needed to nail down the timing with greater certainty. Susan Lozier, Dean and Betsy Middleton and John Clark Sutherland Chair of the College of Sciences, and a professor in the School of Earth and Atmospheric Sciences, has researched the AMOC in the past and is involved in new efforts to directly measure its currents. But the projects began collecting data in 2004 at the earliest, which isn’t enough time to draw firm long-term conclusions. “It is extremely difficult to look at a short record for the ocean overturning and say what it is going to do over 30, 40 or 50 years,” Lozier said.

In May 2023, Ratcliff, an associate professor and co-director of the Interdisciplinary Ph.D. in Quantitative Biosciences, along with Bozdag, a research scientist, released a study on how they developed multicellular colonies from single cells of snowflake yeast. The team showed how the cells evolved to be physically stronger and more than 20,000 times larger than their ancestor. This type of biophysical evolution is a pre-requisite for the kind of large multicellular life that can be seen with the naked eye. Their study is the first major report on the ongoing Multicellularity Long-Term Evolution Experiment (MuLTEE), which the team hopes to run for decades.

<![CDATA[This Hurricane Season Depends on a Showdown in the Atlantic]]> 34434 Like a massive, watery battery, the Atlantic Ocean powers hurricanes. As the ocean warms throughout the summer, it sends moisture into the atmosphere—heat energy that combines with wind to spin up storms. And the surface of the North Atlantic has never been hotter at this time of year — the early stages of hurricane season — at least since routine satellite measurements began in the early 1980s. Because of this change, a showdown over this year’s hurricane season is literally heating up in the Atlantic. Hurricanes could feed on that warm ocean water. But at the same time, an El Niño has also formed in the Pacific and could provide conditions that prevent hurricanes.

Like a massive, watery battery, the Atlantic Ocean powers hurricanes. As the ocean warms throughout the summer, it sends moisture into the atmosphere—heat energy that combines with wind to spin up storms. And the surface of the North Atlantic has never been hotter at this time of year — the early stages of hurricane season — at least since routine satellite measurements began in the early 1980s. Because of this change, a showdown over this year’s hurricane season is literally heating up in the Atlantic. Hurricanes could feed on that warm ocean water. But at the same time, an El Niño has also formed in the Pacific and could provide conditions that prevent hurricanes. Annalisa Bracco, professor in the School of Earth and Atmospheric Sciences, mentions other factors that may influence the 2023 hurricane season.

<![CDATA[Scientists Unearth 20 Million Years of ‘Hot Spot’ Magmatism Under Cocos Plate]]> 34434 Ten years ago, Samer Naif made an unexpected discovery in Earth’s mantle: a narrow pocket, proposed to be filled with magma, hidden some 60 kilometers beneath the seafloor of the Cocos Plate. The observation provided an explanation for how tectonic plates can gradually slide, lubricated by partial melting. The study also “raised several questions about why magma is stored in a thin channel — and where the magma originated from,” says Naif, an assistant professor in the School of Earth and Atmospheric Sciences at Georgia Institute of Technology. Fellow researchers went on to share competing interpretations for the cause of the channel. Naif went looking for clues of mantle magmas that he first observed in his 2013 Nature study. The results of that search are detailed in a new Science Advances article, “Episodic intraplate magmatism fed by a long-lived melt channel of distal plume origin”, co-authored by Naif. (Coverage of this study also appeared at Phys.org and Interesting Engineering.)

<![CDATA[Scientists discover small RNA that regulates bacterial infection]]> 34434 People with weakened immune systems are at constant risk of infection. Pseudomonas aeruginosa, a common environmental bacterium, can colonize different body parts, such as the lungs, leading to persistent, chronic infections that can last a lifetime — a common occurrence in people with cystic fibrosis. But the bacteria can sometimes change their behavior and enter the bloodstream, causing chronic localized infections to become acute and potentially fatal. How and why the switch happens in humans has remained unknown. However, researchers at the Georgia Institute of Technology have identified the major mechanism behind the transition between chronic and acute P. aeruginosa infections. Marvin Whiteley -- professor in the School of Biological Sciences and Bennie H. and Nelson D. Abell Chair in Molecular and Cellular Biology -- and Pengbo Cao, a postdoctoral researcher in Whiteley's lab, discovered a gene that drives the switch. By measuring bacterial gene expression in human tissue samples, the researchers identified a biomarker for the transition.

<![CDATA[Cooperation and Cheating]]> 34434 Cooperation is everywhere. Cells cooperate in multicellular organisms, individuals cooperate in societies, and different species cooperate. Why would it not be the case that microbes cooperate with each other? Researchers have known for more than 20 years that bacteria participate in collective behaviors such as forming biofilms and acquiring nutrients from the environment. But being part of a cooperative group does not necessarily mean that every individual bacterium plays by the rules. Occasionally, cheaters arise. Steve Diggle, professor in the School of Biological Sciences and director of Georgia Tech's Center for Microbial Dynamics and Infection, weighs in on what keeps microbial cheaters from ruining biofilm structures.

This means that by measuring gravitational waves, astrophysicists can peek directly into the heart of some of these most spectacular phenomena in the universe. Since 2020, the Laser Interferometric Gravitational-Wave Observatory — commonly known as LIGO— has been sitting dormant while it underwent some exciting upgrades. These improvements will significantly boost the sensitivity of LIGO and should allow the facility to observe more-distant objects that produce smaller ripples in spacetime. Faculty and students in the School of Physics and Georgia Tech's Center for Relativistic Astrophysics were part of the LIGO Scientific Collaboration when the observatory made the first direct observation of gravitational waves. Laura Cadonati, professor in the School of Physics and associate dean for Research in the College of Sciences, served as LIGO deputy spokesperson and was on its data analysis team.

Faculty and students in the School of Physics and Georgia Tech's Center for Relativistic Astrophysics were part of the LIGO Scientific Collaboration when the observatory made the first direct observation of gravitational waves. Laura Cadonati, professor in the School of Physics and associate dean for Research in the College of Sciences, served as LIGO deputy spokesperson and was on its data analysis team.

A lack of molecules means there is no medium through which sound waves can travel. Essentially, most of the universe is a giant, near-perfect vacuum. But hot turbulent gas in stars produce internal and surface waves which can be picked up by telescopes. Space telescopes also measure wavelengths of light and send that data back to Earth. Sonification allows the astronomical data transmitted by telescopes to then be turned into sound. Sonification is not only creating greater opportunities for scientific inclusion, but helping astronomers to fine-tune their celestial observations. "The auditory system is a fantastic pattern recognition device. We accomplish speech by listening to changes in a person's voice over time. We can use the same capabilities to listen for changes in a dataset," says Bruce Walker, professor in the School of Psychology and the School of Interactive Computing, and director of Georgia Tech's Sonification Lab

We rarely think about how agile our own tongue needs to be to form words or avoid being bitten while helping us taste and swallow food. But that’s just the start of the tongue’s versatility across the animal kingdom. Without tongues, few if any terrestrial vertebrates could exist. The first of their ancestors to slither out of the water some 400 million years ago found a buffet stocked with new types of foods, but it took a tongue to sample them. The range of foods available to these pioneers broadened as tongues diversified into new, specialized forms — and ultimately took on functions beyond eating.

The process could open this summer and is expected to be highly competitive. The idea is to create additional areas of tech expertise in the country, similar to Silicon Valley or Seattle, said Julia Kubanek, vice president of Interdisciplinary Research, and a professor in the School of Biological Sciences and the School of Chemistry and Biochemistry. It could bring more economic development and secure a more reliable domestic supply chain, Kubanek added.

<![CDATA[New Proof Finds the ‘Ultimate Instability’ in a Solar System Model]]> 34434 In most of the numerical simulations that depicted the motions of the solar system's planets in the future, everything proceeded as expected. But in one percent of those simulations, things when literally sideways — thanks to Mercury's orbit flattening, causing chaos to other planet's orbits. Perhaps the solar system was not as stable as people once thought. For centuries, ever since Isaac Newton formulated his laws of motion and gravity, mathematicians and astronomers have grappled with this issue. Now, in three research papers, a trio of scientists have proved for the first time that instability inevitably arises in a model of planets orbiting a sun. Rafael de la Llave, a professor in the School of Mathematics whose speciality is dynamical systems, didn't work on the research papers but is quoted in the article.
