BlackForest Aggregates Threat Information to Warn of Possible Cyber Attacks
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
A recently improved telemedicine system at Marcus Autism Center, which was optimized by scientists at the Georgia Tech Research Institute (GTRI) and Cisco Systems, Inc., is now a showcase for providers of telemedicine.
Agile Aperture Antenna Tested on Aircraft to Survey Ground Emitters, Maintain Satellite Connection
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
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
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
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.
April 10, 2014 -- Researchers have developed a new understanding of the T-cell recognition process by describing how T-cell receptors use mechanical contact – the forces involved in their binding to antigens – to make decisions about whether or not the cells they encounter are threats.
April 7, 2013 - From time to time, living cells will accidentally make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life.
April 6, 2014 -- A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.
March 30, 2014 -- By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer -- operating at temperatures of up to 200 degrees Celsius.
March 26, 2014 -- Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications.
March 26, 2014 - A new robotic system at Georgia Tech’s Center for Chemical Evolution could soon let scientists better simulate and analyze the chemical reactions of early Earth on the surface of real rocks to further test the theory that catalytic minerals on a meteorite’s surface could have jump-started life’s first chemical reactions.
March 24, 2014 - A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.
March 14, 2014 - A new paper in Science describes DNA-based polyhedral shapes that are larger and stronger than scientists have built before. Right now, these are just static shapes. But they provide the scaffolding on which scientists could build robot walkers, or cages with doors that open and close.
March 10, 2014 -- A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules.
March 5, 2014 - The mobile app OneBusAway, which tracks public transportation in real time, now includes arrival times for MARTA trains in addition to the MARTA buses and Georgia Tech shuttles already featured in the app.
