Molecular “hats” allow in vivo activation of disguised signaling peptides
Using molecular "hats," researchers have developed a way to sneak biomaterials containing the signaling molecules into living animals. When the disguised peptides are needed to launch biological processes, the researchers shine ultraviolet light onto the molecules through the skin, causing the “hat” structures to come off.
Carbon soot particles, dust blamed for discoloring India’s Taj Mahal
The Taj Mahal’s iconic marble dome and soaring minarets require regular cleaning to maintain their dazzling appearance, and scientists now know why. Researchers from the United States and India are pointing the finger at airborne carbon particles and dust for giving the gleaming white landmark a brownish cast.
Smaller lidars could allow UAVs to conduct underwater scans
Researchers from the Georgia Tech Research Institute (GTRI) have designed a new approach that could lead to bathymetric lidars that are much smaller and more efficient than the current full-size systems. The new technology would let modest-sized unmanned aerial vehicles (UAVs) carry bathymetric lidars, lowering costs substantially.
Army collaboration produces new test station for missile warning system
Collaboration between the Georgia Tech Research Institute (GTRI) and the Army Reprogramming Analysis Team (ARAT) has led to development of a new integrated support station (ISS) for testing software used in the Army's aircraft missile warning systems.
Researchers develop world’s thinnest electric generator
Researchers have reported the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.
Snakes and snake-like robots show how sidewinders conquer sandy slopes
Researchers report that sidewinder snakes improve their ability to traverse sandy slopes by simply increasing the amount of their body area in contact with the granular surfaces they’re climbing. The information could help search-and-rescue robots traverse such sandy environments.
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.
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.
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.
June 30, 2014 - The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
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.
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.
Winter-Spring Research Horizons -- In August 2013, AT&T opened a Foundry development center in Technology Square, the fourth such product development center the company has opened. AT&T joined development groups for NCR, Panasonic and ThyssenKrupp, all of which wanted to be near Georgia Tech and its innovation ecosystem.
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.
May 29, 2014 -- A study of 338 patients with coronary artery disease has identified a gene expression profile associated with an elevated risk of cardiovascular death. Used with other indicators such as biochemical markers and family history, the profile – based on a simple blood test – may help identify patients who could benefit from personalized treatment and counseling designed to address risk factors.
May 29, 2014 - A new technology under development at the Georgia Institute of Technology could one day provide more efficient delivery of the bone regenerating growth factors with greater accuracy and at a lower cost.
