Marine protected areas might not be enough to help overfished reefs recover

August 22, 2014 - Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle.

Oliver Brand Assumes Top Post at Institute for Electronics and Nanotechnology

August 14, 2014 -- Oliver Brand, a professor in the Georgia Institute of Technology's School of Electrical and Computer Engineering, has been named executive director of the Institute for Electronics and Nanotechnology (IEN), one of nine interdisciplinary research institutes (IRIs) at Georgia Tech.

Multiple UAVs Perform Autonomous Formation Flight

August 7, 2014 -- In one of the first autonomous demonstrations, the Georgia Tech Research Institute (GTRI) has successfully commanded three fully autonomous, collaborating UAVs. The machines flew in close formation at the same altitude, separated by approximately 50 meters as they executed figure-eight patterns.

BlackForest Aggregates Threat Information to Warn of Possible Cyber Attacks

July 23, 2014 -- Researchers have developed a new open source intelligence gathering system designed to create a picture of developing threats. BlackForest complements other GTRI systems designed to help corporations, government agencies and nonprofit organizations battle increasingly-sophisticated threats to their networks.

Improved Telemedicine System Connects Doctors to Autism Patients in Rural Georgia

July 21, 2014 - A recently improved telemedicine system was optimized by scientists at the Georgia Tech Research Institute (GTRI) and Cisco Systems, Inc. The system at Marcus Autism Center’s telemedicine room is now a showcase for providers of telemedicine, where improved video capabilities and an ergonomic suite allow patients in rural Georgia to meet face-to-face with medical specialists in Atlanta.

Agile Aperture Antenna Tested on Aircraft to Survey Ground Emitters, Maintain Satellite Connection

July 9, 2014 -- The Georgia Tech Research Institute’s software-defined, electronically-reconfigurable Agile Aperture Antenna (A3) has now been tested on the land, sea and air. Department of Defense representatives were in attendance during a recent event where two of the low-power devices, which can change beam directions in a thousandth of a second, were demonstrated in an aircraft during flight tests.

Hollow-Fiber MOF Membranes Could Cut Separation Costs, Energy Use

July 3, 2014 -- Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication process, believed to be the first to grow MOF membranes inside hollow fibers, could potentially change the way large-scale energy-intensive chemical separations are done.

Stanley Miller’s Forgotten Experiments, Analyzed

June 25, 2014 - Stanley Miller, the chemist whose landmark experiment published in 1953 showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never analyzed. The first-ever analysis of some of Miller’s old samples has revealed another way that important molecules could have formed on early Earth.

Synthetic Aperture Sonar to Help Navy Hunt Sea Mines

June 18, 2014 - Since World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other means of attack combined, according to a Navy report on mine warfare. New sonar research being performed by the Georgia Tech Research Institute (GTRI) could improve the Navy’s ability to find sea mines deep under water.

How Red Tide Knocks Out Its Competition

June 4, 2014 - New research reveals how the algae behind red tide thoroughly disables – but doesn’t kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem.
