  • Surface Diffusion Plays a Key Role in Defining the Shapes of Catalytic Nanoparticles

    April 9, 2013 - Controlling the shapes of nanometer-sized catalytic and electrocatalytic particles made from noble metals such as platinum and palladium may be more complicated than previously thought.

  • Georgia Tech Tools Enable Groundbreaking Gas Research

    March 1, 2013 - Scientists are now better able to examine rare methane gas samples recovered from deep beneath the seafloor using innovative tools developed by Georgia Tech.  

  • 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.

  • 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 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.

  • 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.

  • Researchers Contribute to Instrument for Remotely Measuring Hurricane Intensity

    December 12, 2012 - A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.

  • Gulf of Mexico Clean-Up Makes 2010 Spill 52-Times More Toxic

    November 30, 2012 - If the 4.9 million barrels of oil that spilled into the Gulf of Mexico during the 2010 Deep Water Horizon spill was a ecological disaster, the two million gallons of dispersant used to clean it up apparently made it even worse – 52-times more toxic. That’s according to new research from the Georgia Institute of Technology and Universidad Autonoma de Aguascalientes (UAA), Mexico.

  • Research Will Study How Diversity Helps Microbial Communities Respond to Change

    November 26, 2012 - Researchers at the Georgia Institute of Technology have received a five-year, $1.8 million grant from the National Science Foundation (NSF) to study how complex microbial systems use their genetic diversity to respond to human-induced change. The work is important because these microbial communities play critical roles in the environment, breaking down pollutants, recycling nutrients – and serving as major sources of nitrogen and carbon.
