This story about an AI enhancement of the famous 2018 photo of the first-ever image of a black hole — captured by the Event Horizon Telescope featuring EHT founding members and School of Physics professors Feryal Ozel (also school chair) and Dimitrios Psaltis — is also covered in Scientific American,
Precisely how multicellular organisms evolved from single-celled ancestors remains poorly understood. The transition happened hundreds of millions of years ago, and early multicellular species are largely lost to extinction. To investigate how multicellular life evolves from scratch, researchers from the Georgia Institute of Technology decided to take evolution into their own hands.
A team of mechanical engineering students and alumni at Georgia Tech began developing and testing ForageFeeder, a $400 machine partly inspired by deer feeders that can disperse gorillas’ their meals at random intervals and locations throughout the day. Much like modern humans, zoo animals frequently deal with obesity due to a lack of activity. Tools and techniques such as the ForageFeeder not only promote Zoo Atlanta gorillas’ movement, but better simulate their natural foraging world.
A small but growing group of researchers is fascinated by an organ we often take for granted. 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.
In this story about the puzzling behavior that goes on inside black holes, Quanta Magazine uses the 2017 first-ever image of the black hole at the heart of the M87 galaxy captured by an Event Horizon Telescope research team. That team included EHT founding members Feryal Özel, professor and chair of the School of Physics, and Dimitrios Psaltis, a professor in the School.
After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves — tiny ripples in space itself that travel through the universe. Unlike light waves, gravitational waves are nearly unimpeded by the galaxies, stars, gas, and dust that fill the universe.
Researchers at Seton Hill University, Pennsylvania State University, and the Georgia Institute of Technology looked to the mudskipper, the amphibious fish that spends more than half of its adult life on land to study the evolution of blinking. The study, published in an April edition of Proceedings of the National Academy of Sciences, suggests that blinking
Georgia Tech researchers have been selected by NASA to lead a $7.5 million center that will study the lunar environment and the generation and properties of volatiles and dust. The Center for Lunar Environment and Volatile Exploration Research (CLEVER) will be led by Thomas Orlando, professor in the School of Chemistry and Biochemistry with an adjunct appointment in the School of Physics.
The heart’s electrical system keeps all its muscle cells beating in sync. A hard whack to the chest at the wrong moment, however, can set up unruly waves of abnormal electrical excitation that are potentially deadly. The resulting kind of arrhythmia may be what caused the football player Damar Hamlin of the Buffalo Bills to collapse on the field after he took a powerful hit during a 2023 National Football League game.
Human beings for millennia have gazed with awe at the vast torrent of stars — bright and dim — shining in Earth's night sky that comprise the Milky Way. Our home galaxy, however, is now being observed for the first time in a brand new way. Scientists said on Thursday they have produced an image of the Milky Way not based on electromagnetic radiation - light - but on ghostly subatomic particles called neutrinos.
