Marine protected areas might not be enough to help overfished reefs recover
Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs.
Oliver Brand Assumes Top Post at Institute for Electronics and Nanotechnology
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
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
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.
Research Horizons Winter-Spring 2014 -- Materials research is a major priority at Georgia Tech that involves some 200 faculty members. Major research areas include materials for electronics, infrastructure, energy, environment, transportation, biotechnology, aerospace and defense.
April 17, 2014 -- Using a mix of theoretical and computer-based approaches, researchers are trying to predict the dynamics of events such as black holes devouring stars, a scenario also known as a "tidal disruption."
April 16, 2014 -- Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer that mimics the brain's operation.
April 14, 2014 - Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.
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.
