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.

Model Finds Common Muscle Control Patterns Governing the Motion of Swimming Animals

June 4, 2013 — What do swimmers like trout, eels and sandfish lizards have in common? According to a new study, the similar timing patterns that these animals use to contract their muscles and produce undulatory swimming motions can be explained using a simple model. Scientists have now applied the new model to understand the connection between electrical signals and body movement in the sandfish.

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.

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.

Ronald L. Johnson, retired 2-star Army General, tapped for Managing Director of Tennenbaum Institute and Professor of Practice in ISyE.

Ron Johnson tapped for Managing Director of the Tennenbaum Institute and Professor of Practice in ISyE

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.

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.

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.

2012 In Review

December 20, 2012 — 2012 has been a year of milestones and accomplishments for Georgia Tech. Enjoy taking a look back at some of the highlights.

Georgia Tech Power Cell Among Top 10 Physical Science Breakthroughs in 2012

December 14, 2012 — A power cell that directly converts mechanical energy to chemical energy – which can then be stored and converted to electrical energy – has been selected as one of 2012’s top breakthroughs in the physical sciences by Physics World magazine.
