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.
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.
March 5, 2014 - A new study found that neural circuits in the brain rapidly multitask between detecting and discriminating sensory input, such as headlights in the distance. That’s different from how electronic circuits work, where one circuit performs a very specific task. The brain, the study found, is wired in way that allows a single pathway to perform multiple tasks.
February 26, 2014 -- The annual ritual of visiting a doctor’s office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine. The research, which involved nearly 100 people recruited in the metropolitan Atlanta area, found that test subjects could successfully apply a prototype vaccine patch to themselves.
February 24, 2014 - A new study found evidence that assessing the route to cancer on a case-by-case basis might make more sense than basing a patient’s cancer treatment on commonly disrupted genes and pathways.
February 21, 2014 - To help coordinate a rapid response to pandemics, a professor at Georgia Tech has designed software that combines biological data on the pandemic with demographic data of the at-risk population so that health officials can develop a game plan to limit the pandemic’s spread.
February 19, 2014 -- Researchers have released a new version of the Chemical Companion Decision Support System (CCDSS), a software system that provides first responders with detailed and easy-to-access information about chemicals that may be associated with hazmat incidents.
February 18, 2014 -- Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart.
