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.

And the Oscar (and Thanks) Goes To…

February 19, 2013 — Georgia Tech student Rebecca Rolfe analyzed 60 years of Academy Awards acceptance speeches as part of a research project that focused on gratitude. She has outlined the trends and patterns on an interactive website.

Pollution Doesn’t Change the Rate of Cloud Droplet Formation, Study Shows

February 18, 2013 — When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn’t matter that much. And that’s good news for reducing the uncertainty of climate model predictions.

Designer Blood Clots: Artificial Platelets Could Treat Injured Soldiers on the Battlefield

February 15, 2013 — When it comes to healing the terrible wounds of war, success may hinge on the first blood clot – the one that begins forming on the battlefield right after an injury.

Sticky Cells: Cyclic Mechanical Reinforcement Extends Longevity of Bonds Between Cells

February 14, 2013 — A new study provides insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It’s thought that abnormalities in their ability to do so play an important role in a broad range of disorders.

Video Study Shows Picky Eater Fish Threaten Endangered Coral Reefs

February 12, 2013 — Using underwater video cameras to record fish feeding on South Pacific coral reefs, scientists have found that herbivorous fish can be picky eaters – a trait that could spell trouble for endangered reef systems.

Study Shows that Gases Work with Particles to Promote Cloud Formation

February 4, 2013 — Researchers have published a study in the online Early Edition of the journal Proceedings of the National Academy of Sciences (PNAS) showing – for the first time – that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists.

Agilent Technologies Commits $90 Million Gift of Software to Georgia Institute of Technology

February 4, 2013 — Agilent Technologies Inc. (NYSE: A) today announced the largest in-kind software donation ever in its longstanding relationship with the Georgia Institute of Technology.

Georgia Tech Energy Director Appointed to National Petroleum Council

February 1, 2013 — Tim Lieuwen, executive director of the Georgia Tech Strategic Energy Institute, has been appointed to the National Petroleum Council (NPC) by the secretary of the U.S. Department of Energy. Lieuwen, who is also a professor of aerospace engineering at Georgia Tech, will serve on the council of about 20 people that advises the secretary on matters relating to oil and natural gas.

Georgia Tech Awarded $2.3 Million to Improve Energy Efficiency of Military HVAC Systems

January 30, 2013 — The Georgia Institute of Technology has been awarded $2.3 million from the U.S. Department of Defense to help improve the efficiency of heating and air conditioning systems on the battlefield.

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.
