Free electron lasers (FELs), which are driven by kilometer-long linear accelerators, emit bursts of short-wavelength light lasting one quadrillionth of a second. As a result, they can act as strobe lights for viewing the fastest events in nature — atomic or molecular motion — and therefore promise to revolutionize our understanding of almost any kind of matter. New research shows how to measure the super-short bursts of high-frequency light emitted from FELs.
Researchers from Georgia Tech have been conducting experiments designed to show the simplest of robots can still accomplish tasks. The team created a group of robots they call BOBbots, which stands for “behaving, organizing, buzzing bots.” One of the researchers in Dan Goldman, Dunn Family Professor in the School of Physics.
For the most part, animals don't get heart attacks — not even one of our closest living relatives, chimpanzees. Nonhuman animals experience other cardiac problems, but as far as scientists know, heart attacks are rare in other creatures. One of the scientists looking into this is Flavio Fenton, professor in the School of Physics, who has conducted extensive research into cardiac dynamics in humans and animals.
A team of researchers led by Dana Randall, ADVANCE Professor in the College of Computing, and Daniel Goldman, Dunn Family Professor in the School of Physics, sought to show that even the simplest of robots can still accomplish tasks well beyond the capabilities of one, or even a few, of them.
Researchers from Georgia Tech and the University of Tennessee–Knoxville uncovered hidden and unexpected quantum behavior in a rather simple iron-iodide material (FeI2) that was discovered almost a century ago.
A snake-like robot has been developed that can burrow through sand or loose soil. Researchers at the University of California Santa Barbara & Georgia Institute of Technology have taken their cues from plants & animals that have evolved to navigate subterranean spaces. They say they have "developed a fast, controllable soft robot that can burrow through sand.” The team is working on a project with NASA to develop burrowing for the moon or even more distant bodies, like Enceladus, a moon of Jupiter.
Astronomers have definitively detected a black hole devouring a neutron star for the first – and second – time. These cataclysmic events created ripples in space-time called gravitational waves that travelled more than 900 million light years to reach detectors on Earth.
Scientists are learning a lot about swarm intelligence by studying worms, which have been observed grouping together in balls and acting like a liquid. Researchers at Georgia Tech published an article after studying the behaviors of the California blackworm — and designed a robotic model to mirror the worms’ behavior.
According to a new Georgia Tech study, honeybees have developed a way to convert pollen particles into viscoelastic pellets, allowing them to be efficiently, quickly, and reliably transported to the hive. The study also suggests that insects remove pollen from their bodies at a rate 2-10 times slower than normal grooming rates.
Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms. Georgia Tech scientists report that over the course of nearly two years of evolution, they have induced unicellular yeasts to grow into multicellular clusters of immense size, going from microscopic to branching structures visible to the naked eye.
