Blimps are indeed part of this "Innovations" roundup, but it's the collaborative abilities of army ants that have led engineers from Northwestern University and the New Jersey Institute of Technology to speculate that the insects' behavioral principles and brains could one day be used to program swarms of robots. David Hu, professor in the School of Biological Sciences and the George W. Woodruff School of Mechanical Engineering (with an adjunct appointment in the School of Physics), is quoted regarding his research on fire ant raft constructions during flooding, comparing the insects to neurons in one large brain.

Ever wondered why your dog’s back-and-forth shaking is so effective at getting you soaked? Or how bugs, birds, and lizards can run across water—but we can’t? Or how about why cockroaches are so darn good at navigating in the dark? Those are just a few of the day-to-day mysteries answered in the new book How to Walk on Water and Climb Up Walls: Animal Movement and the Robots of the Future, by David Hu, professor in the School of Biological Sciences and the George W. Woodruff School of Mechanical Engineering, with an adjunct appointment in the School of Physics. The book answers questions you probably won’t realize you even had, but they’re questions with serious answers that span the worlds of physics, fluid mechanics, and biology. Throughout the book, Hu demonstrates the extraordinary value day-to-day curiosity brings to science.

Georgia Tech scientists will soon have another way to search for neutrinos, those hard-to-detect, high-energy particles speeding through the cosmos that hold clues to massive particle accelerators in the universe—if researchers can find them. "The detection of a neutrino source or even a single neutrino at the highest energies is like finding a holy grail," says Nepomuk Otte, professor in the School of Physics. Otte is the principal investigator for the Trinity Demonstrator telescope that was recently built by his group and collaborators, and was designed to detect neutrinos after they get stopped within the Earth.

Isabella Muratore at the New Jersey Institute of Technology says studying army ants comes with certain occupational hazards, like their very aggressive nature. But what's truly remarkable is when the ants encounter obstacles — such as a gap between leaves or branches — they build living bridges out of their bodies, hooking themselves together like a barrel of monkeys. This story includes comments from David Hu, professor in the School of Biological Sciences and the George W. Woodruff School of Mechanical Engineering, with an adjunct appointment in the School of Physics. Hu has studied how fire ants use their bodies to build rafts. He says this type of work reveals how ants make collective decisions, which could have implications for controlling swarms of robots. (This story was also covered on Houston Public Media, Georgia Public Broadcasting, and National Public Radio.)

A new computer simulation of the early universe has been built by researchers, and it closely matches data obtained with the James Webb Space Telescope (JWST). The results, which were presented in The Open Journal of Astrophysics, were obtained by Maynooth University and Georgia Tech researchers. They demonstrate that the data obtained with JWST are consistent with theoretical expectations. The team’s “Renaissance simulations” are a set of extremely complex computer models of galaxy formation in the early universe. The School of Physics researchers are John Wise, Professor and Director of the Center for Relativistic Astrophysics (CRA), and Samantha Hardin, graduate student. (This study was also covered at CityLife, Silicon RepublicSciTechDailyPhys.org and List23.)

An annular "ring of fire" eclipse will stretch from Oregon to Texas next Saturday, October 14. 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)

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

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. 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.)

Robotics engineers have worked for decades, using substantial funding, to create robots that can walk or run with the ease of animals. Despite these efforts, today’s robots still cannot match the natural abilities of many animals in terms of endurance, agility, and robustness. Seeking to understand and quantify this disparity, an interdisciplinary team of scientists and engineers from top research institutions, including Dunn Family Associate Professor at the School of Physics and the School of Biological Sciences Simon Sponberg, conducted a comprehensive study to compare various aspects of robotic systems designed for running with their biological counterparts.

A group of researchers at the Georgia Institute of Technology have created the world’s first functional semiconductor made from graphene, a development that could lead to advanced electronic devices and quantum computing applications. Seen as the building block of electronic devices, semiconductors are essential for communications, computing, healthcare, military systems, transportation and countless other applications. Semiconductors are typically made from silicon, but this material is reaching its limit in the face of increasingly faster computing and smaller electronic devices, according to the Georgia Tech research team who published their findings in Nature earlier this year. In a drive to find a viable alternative to silicon, Walter de Heer, Regents' Professor in the School of Physics, led a team of researchers based in Atlanta, Georgia and Tianjin, China to produce a graphene semiconductor that is compatible with microelectronics processing methods.

The stars aligned to give a Georgia Tech undergraduate student and an alum the moment of a lifetime during the recent solar eclipse. Corinne Hill is currently majoring in physics with a concentration in astrophysics. Nathaniel Greve graduated in 2023 with a degree in computer science. The couple met in 2021 when they both played alto saxes in the Georgia Tech marching band. After being unable to experience totality in 2017, Greve said the pair made plans to go to Wapakoneta, Ohio, for 2024′s eclipse. Hill’s friends in the Astronomy Club went to the Ozarks to experience the eclipse, but Hill agreed to go to Ohio instead.

It’s been 10 years since the Air Force Research Laboratory, or AFRL, successfully launched the astronomy outreach program called Aloha Explorations at the Air Force Maui Optical and Supercomputing site, or AMOS, in Maui, Hawaii. 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.
