GTRI Agile Aperture Antenna Technology is Tested on an Autonomous Ocean Vehicle

June 18, 2013 — Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.

Moving Iron in Antarctica

June 12, 2013 — Georgia Tech research indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there’s not enough iron to go around, and the added iron may stimulate less productivity than expected.

Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

June 11, 2013 — Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures – including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Borneo Stalagmites Provide New View of Abrupt Climate Events Over 100,000 Years

June 6, 2013 — A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events. The 100,000-year climate record adds to data on past climate events, and may help scientists assess models designed to predict how the Earth’s climate will respond in the future.

Study Finds Substantial Microorganism Populations in the Upper Troposphere

January 28, 2013 — In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms – principally bacteria – in the middle and upper troposphere, that section of the atmosphere approximately four to six miles above the Earth’s surface.

Georgia Tech Partners to Improve Prosthetic Socket for Veteran Amputees

January 16, 2013 — Researchers at Georgia Tech are major players in a team that will develop an advanced prosthetic socket system that could offer better comfort, functionality and mobility for military-veteran amputees.

Aerial Platform Supports Development of Lightweight Sensors for UAVs

January 16, 2013 — A research team at the Georgia Tech Research Institute (GTRI) is developing an airborne testing capability for sensors, communications devices and other airborne payloads. This aerial test bed, called the GTRI Airborne Unmanned Sensor System (GAUSS), is based on an unmanned aerial vehicle (UAV) made by Griffon Aerospace and modified by GTRI.

Farrokh Ayazi Named 2013 IEEE Fellow

January 16, 2013 — Farrokh Ayazi, a professor in the School of Electrical and Computer Engineering, is among the 298 individuals worldwide named as a 2013 IEEE Fellow.

Study Quantifies the Size of Holes Antibacterials Create in Cell Walls to Kill Bacteria

January 9, 2013 — Researchers recently created a biophysical model of the response of a Gram-positive bacterium to the formation of a hole in its cell wall, then used experimental measurements to validate the theory, which predicted that a hole in the bacteria cell wall larger than 15 to 24 nanometers in diameter would cause the cell to lyse, or burst.

Spear Phishing: Researchers Work to Counter Email Attacks that Gain Recipients’ Trust

January 8, 2013 — Researchers at the Georgia Tech Research Institute (GTRI) are working to counter threats from spear phishing. The attacks use knowledge of computer users to gain their trust to break into corportate networks.

Improving Flood Predictions in Developing Nations

January 8, 2013 — Georgia Tech researchers have created a hydrological model that forecasts flooding in Pakistan as many as ten days in advance.

Coral Records Suggest that Recent El Nino Activity Rises Above Noisy Background

January 3, 2013 — By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate cycle that affects climate worldwide. The new information will help assess the accuracy of climate model projections for 21st century climate change in the tropical Pacific.

January 3, 2013 — Ronald L. Johnson, retired 2-Star Army General and graduate of ISyE, has accepted a joint appointment at Georgia Tech. Effective January 2, 2013, he will serve as a Professor of Practice in ISyE, and the Managing Director of the Tennenbaum Institute.

Clays on Mars: More Plentiful Than Expected

December 20, 2012 — A new study co-authored by the Georgia Institute of Technology indicates that clay minerals, rocks that usually form when water is present for long periods of time, cover a larger portion of Mars than previously thought.
