Georgia Tech physicist Jennifer Rieser, who studies snake slithering, but was not involved in this new study, tells NPR that the research is a “cool” finding. The paper provides evidence that the way the snake moves in the air "actually seems to have a pretty important consequence for their movement,” she says. Related coverage: NPR.
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. There may be pockets of the universe where temperatures drop to 1 Kelvin above absolute zero, astronomer Jim Sowell of the Georgia Institute of Technology notes, but so far, the closest measurement to absolute zero has only been observed in laboratories here on Earth.
"We performed simulations of black-hole collisions using supercomputers and then compared the rapidly changing shape of the remnant black hole to the gravitational waves it emits." Christopher Evans, co-author and graduate student from the Georgia Institute of Technology, said. Read more: Ars Technica Futurism
It was a long and storied path for Dr. James “Jim” Sowell to get the 20-inch, Italian Officina Stellare telescope installed on the roof of the Howey Physics Building. But he succeeded, and today during Public Nights, young stargazers not only have access to Georgia Tech’s Observatory, they’re also learning about the solar system, stars, galaxies, and the universe, as well as astro-particle, electromagnetic, gravitational, and stellar astrophysics.
Physicists and biologists challenge a prevailing evolutionary theory that single-celled organisms can only evolve to become multicellular life forms if doing so increases their overall productivity.
“Rather than each cell producing what it needs, specialised cells need to be able to trade with each other. Previous work suggests that this only happens as long as the overall group’s productivity keeps increasing,” explains lead author David Yanni, PhD student at Georgia Institute of Technology, Atlanta, US.
“We can’t see the very first generations of stars,” said study co-author John Wise, an associate professor at the Center for Relativistic Astrophysics at Georgia Tech. “Therefore, it’s important to actually look at these living fossils from the early universe, because they have the fingerprints of the first stars all over them through the chemicals that were produced in the supernova from the first stars.”
This paper refined the current understanding of how fish navigate their underwater world could provide insights that can be applied to underwater robots, according to Science News. Robots are often designed with separate apparatus for movement and sensing, but, as Simon Sponberg, a biophysicist at the Georgia Tech, tells Science News, “biology puts sensors on everything.”
Luckily, a team of researchers from Georgia Tech's Center for Relativistic Astrophysics recently conducted simulations that show what the formation of the first stars looked like.
Physicist Elisabetta Matsumoto is an avid knitter and has been since taking up the hobby as a child. Matsumoto, now at the Georgia Institute of Technology in Atlanta, is teasing out the mathematical rules that dictate how stitches impart such unique properties to fabrics.
