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.
Research Horizons Summer 2008 -- Independent patenting activity has grown rapidly in Georgia over the past 30 years, with more than 9,000 patents issued since 1975 to inventors not associated with corporations, universities or similar organizations. A new study has found that nearly half of the products created by these inventors were in non-consumer areas.
Research Horizons Summer 2008 -- The Oculus airborne test platform is under development by Georgia Tech Research Institute (GTRI) researchers in collaboration with West Virginia University. The project is sponsored by the U.S. Department of Defense.
July 31, 2008 -- The Georgia Tech Research Institute (GTRI) has won a contract to support development of a roadmap designed to improve the testing and evaluation of unmanned and autonomous systems for the U.S. Office of the Secretary of Defense (OSD).
July 14, 2009 -- A report published in the July 8 issue of the journal PNAS is the first to describe the principles behind the stability and electronic properties of tiny nanoclusters of metallic gold. The study found that the clusters are stable because they behave like "superatoms" and exhibit a "divide and protect" bonding structure -- a core of gold atoms and a protective layer of gold-thiolate complexes.
July 8, 2008 -- Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce more light. New research provides insight into factors that influence the injection efficiency.
July 2, 2008 -- Research at the Georgia Institute of Technology shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone.
June 30, 2008 -- A new assistive technology allows individuals with disabilities to operate a computer, control a powered wheelchair and interact with their environments simply by moving their tongues. The Tongue Drive system, developed by engineers at the Georgia Institute of Technology, could help individuals with severe disabilities lead more independent lives.
June 27, 2008 -- Researchers have shown that a new class of ultraviolet photodiode could help meet the U.S. military's pressing requirement for compact, reliable and cost-effective sensors to detect anthrax and other bioterrorism agents in the air.
June 23, 2008 -- Genetic studies on small organisms such as worms and flies can now be done more quickly using a new microfluidic device developed by engineers at the Georgia Institute of Technology. The new "lab-on-a-chip" can automatically position, image, determine the phenotype of and sort small animals, such as the worm Caenorhabditis elegans that is commonly used for biological studies.
June 20, 2008 -- The Georgia Institute of Technology has received a contract to help develop “intelligent binoculars” that mimic the low-level image processing done by the human brain. Called the Cognitive Technology Threat Warning System (CT2WS), the device is expected to be far more capable than portable visual threat-warning equipment currently used by the U.S. military.
