Molecular “hats” allow in vivo activation of disguised signaling peptides

December 15, 2014 -- 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

December 10, 2014 -- 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

December 3, 2014 -- 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.

Dynamic graph analytics tackle social media and other big data

November 6, 2014 -- Researchers at the Georgia Tech Research Institute (GTRI) are bringing graph analytics to bear on a range of data-related challenges, developing advanced technology that can help investigate social networks, surveillance intelligence, computer-network functionality, industrial control systems, and more.

Georgia Institute of Technology receives Grand Challenges Explorations grant from Bill & Melinda Gates Foundation

November 4, 2014 - Georgia Tech announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation. J. Carson Meredith, professor in the School of Chemical & Biomolecular Engineering (ChBE) will pursue an innovative global health and development research project, titled “Pollen-Based Assays of Intestinal Mucus Water Content and Rheology.”

Army collaboration produces new test station for missile warning system

October 22, 2014 -- 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

October 15, 2014 -- 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

October 9, 2014 -- 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.

Automated imaging system looks underground to help improve crops

October 9, 2014 -- Researchers have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The work could help plant scientists improve food crops to help meet the needs of a growing world population.
