New Technique Controls Autonomous Vehicles in Extreme Conditions

At the Georgia Tech Autonomous Racing Facility, researchers are studying a one-fifth-scale autonomous vehicle as it traverses a dirt track. The work will help the engineers understand how to help driverless vehicles face the risky and unusual road conditions of the real world. (Credit: Rob Felt, Georgia Tech)

Georgia Tech researchers have devised a novel way to help keep a driverless vehicle under control as it maneuvers at the edge of its handling limits.

Hearing snap, crackle, pop may help heal your knee

MEMS microphones and piezoelectric strips pick up sounds of a bending and extending knee. Prof. Omer Inan is engineering a device to convert knee joint sounds into a signal he hopes medical researchers will be able to use.

New acoustic device research reveals even a healthy knee makes cringeworthy sounds. But the audio can be turned into graphs, and researchers hope they will some day become medically useful.

40-Year Math Mystery and Four Generations of Figuring

Georgia Tech mathematicians Xingxing Yu, Yan Wang and Dawei He have offered a proof of the Kelmans-Seymour Conjecture nearly 40 years after Princeton Mathematician Paul Seymour made it in 1977.

In social media and much computer technology, a field of math called Graph Theory is used to make networks work. Georgia Tech mathematicians have solved a 40-year Graph Theory mystery.

Heme, a Poisonous Nutrient, Tracked by ‘Green Lantern’ Sensor

A tailor-made ratiometric sensor makes a baker's yeast cell light up green, as Georgia Tech scientists use it to track the movements of the essential toxin heme.

Tracking heme has dispelled a widely held assumption that it does not float freely in cellular pools.

Gravitational Waves Detected Again

This illustration shows the merger of two black holes and the gravitational waves that ripple outward as the black holes spiral toward each other. The black holes—which represent those detected by LIGO on Dec. 26, 2015—were 14 and 8 times the mass of the sun, until they merged, forming a single black hole 21 times the mass of the sun. In reality, the area near the black holes would appear highly warped, and the gravitational waves would be difficult to see directly. Image credit: LIGO/T. Pyle

A tiny mirror could make a huge difference for scientists trying to understand what’s happening in the micron-scale structures of living cells.

Robot Helps Study How First Land Animals Moved 360 Million Years Ago

Researchers studied the motion of mudskippers to understand how early terrestrial animals might have moved about on mud and sand, including sandy slopes. This animal was photographed at the Georgia Aquarium in Atlanta.  (Credit: Rob Felt, Georgia Tech)

A new study used a robot to help understand how the first land animals moved about.

Insights on Sex and Death from a Mutant Roundworm

Patrick McGrath holds up dishes with two lab strains of the C. elegans roundworm. Strain LSJ2 (dish on right) dramatically changed its survival strategy to live longer and have fewer offspring due to a tiny mutation on its NURF-1 gene. Researchers at Georgia Tech confirmed the effects of the mutation by duplicating it in lab strain N2 (dish on left) via an injection with CRISPR Cas9.

Do genetic regulators guide survival strategies in hard times? A tiny mutation in a roundworm says they may well.

Schizophrenia Simulator: When Chemistry Upends Sanity's Balance

The schizophrenia simulator is a well-ordered, fine-tuned labyrinth of data from thousands of studies mathed with differential equations to be highly accurate. But the output to users is simple and playful -- a rainbow-colored mobile that displays the dynamics of the brain chemicals' interplay.
Aug 04, 2016 - Atlanta, GA
Working memory disturbances wreck the mental coherence of schizophrenia sufferers, yet treatments for it are very limited. Biomedical engineers have built an accurate simulator of the brain chemistry behind it to help drug developers change that.
