Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers at Georgia Tech and clinicians at Emory University School of Medicine are bringing a new understanding to these complicated conditions with the first high-resolution visualizations of stable spiral waves in human ventricles.

NASA is preparing to enter a new space age from Florida's space coast, and a scientist in Georgia is helping newly tapped Artemis astronauts step onto the moon with next-generation suits. Thom Orlando, professor in the School of Chemistry and Biochemistry, and the School of Physics, is a co-founder of the Center for Space Technology and Research.

Astronauts could return to the moon in a few years, and if they do, they might be wearing spacesuits designed with the help of Thom Orlando, professor in the School of Chemistry and Biochemistry, and the School of Physics. Orlando, who is also a co-founder of Georgia Tech's Center for Space Technology and Research, spoke with GPB's Peter Biello about the science of spacesuit design.

A recently discovered, never-before-seen phenomenon in a type of quantum material could be explained by a series of buzzing, bee-like “loop-currents.” The discovery from physicists at the University of Colorado Boulder (CU Boulder) and Georgia Tech may one day help engineers develop new types of devices, such as quantum sensors, or the quantum equivalent of computer memory storage devices.

October is National Disabilities Employment Awareness Month, and The Able Channel is celebrating by raising awareness about the importance of work for those living and working with disability. Hosted by Paralympic Gold Medal-winning swimmer Mallory Weggeman, "Together We Are Able" showcases the stories of 10 Americans who have redefined perceptions of what the word able is all about. College of Sciences Advisory Board member Paul S.

In a physics lab in Amsterdam, there’s a wheel that can spontaneously roll uphill by wiggling. This “odd wheel” looks simple: just six small motors linked together by plastic arms and rubber bands to form a ring about 6 inches in diameter.

Although it’s understood that water ice exists below the lunar regolith (broken rock and dust), scientists don’t yet know whether surface ice frost covers the floors inside cold, dark craters. NASA is sending Lunar Flashlight, a small satellite (or SmallSat) no larger than a briefcase to find out. The mission, which will use lasers to shed light on those dark craters, will launch in mid-November aboard a SpaceX Falcon 9 rocket.

Retired engineer Tom Crowley proves that you can play around with a hobby you love and see it grow into something extraordinary. The 80-year-old has turned his love of astronomy into consulting work with Georgia Tech's Aloha Telescope outreach program.

Scientists with the IceCube Neutrino Observatory in Antarctica have now analyzed a decade's worth of such neutrino detections and discovered evidence that an active galaxy called Messier 77 (aka the Squid Galaxy) is a strong candidate for one such high-energy neutrino emitter, according to a new paper published in the journal Science.

The Artemis 1 mission to the Moon, launched from Kennedy Space Center on Nov. 16, did not have astronauts on board. It did have what NASA is calling "moonikins" — dummies wearing special spacesuits that will measure data on vibration, acceleration, and cosmic radiation.
