Cloud Formation: Study Shows Insoluble Dust Particles Can Form Cloud Droplets that Affect Global and Regional Climate

October 13, 2011 — New information on the role of insoluble dust particles in forming cloud droplets could improve the accuracy of regional climate models, especially in areas of the world that have significant amounts of mineral aerosols in the atmosphere. A more accurate accounting for the role of these particles could also have implications for global climate models.

Helping Children: FDA Grant Launches Atlanta Pediatric Device Consortium

October 12, 2011 — A two-year, $1.8 million grant from the Food and Drug Administration will launch the new Atlanta Pediatric Device Consortium and foster the development of medical devices for children.

Transformative Research: Georgia Tech Researchers Receive Three NSF Emerging Frontiers Awards

September 29, 2011 — The National Science Foundation has awarded $6 million through its Division of Emerging Frontiers in Research and Innovation to fund three projects involving researchers from the Georgia Institute of Technology.

Breaking Down Plastics: New Standard Specification May Facilitate Use of Additives that Trigger Biodegradation of Oil-Based Plastics in Landfills

September 27, 2011 — Researchers at the Georgia Institute of Technology are working with the Atlanta-based Plastics Environmental Council (PEC) to expand the use of chemical additives that cause oil-based plastic packaging such as water bottles, milk bottles and Styrofoam cups to biodegrade in landfills.

Growing Graphene: “Confinement Controlled Sublimation” Produces High Quality Graphene on Silicon Carbide by Controlling Silicon Evaporation

September 22, 2011 — Georgia Tech scientists have for the first time provided details of their “confinement controlled sublimation” technique for growing high-quality layers of epitaxial graphene on silicon carbide wafers. The technique relies on controlling the vapor pressure of gas-phase silicon in the high-temperature furnace used for fabricating the material.

Stem Cell Signaling: Transformative NIH Grant Will Support Development of Tissue Regeneration Therapeutics for Traumatic Injuries

September 20, 2011 — The National Institutes of Health has awarded nearly $2 million to researchers at the Georgia Institute of Technology and Emory University to develop a new class of therapeutics for treating traumatic injuries and degenerative diseases.

Organism Diversity: Fast-Evolving Genes Control Developmental Differences in Social Insects

September 19, 2011 — A new study found that genes involved in creating different sexes, life stages and castes of fire ants and honeybees evolved more rapidly than genes not involved in these processes. The fast-evolving genes also exhibited elevated rates of evolution before they were recruited for development.

Restoring Reefs: Study Underway in Aquarius Underwater Laboratory May Help Manage Seaweed-Eating Fish that Protect Coral Reefs

September 15, 2011 — A team of researchers from the Georgia Institute of Technology is using the Aquarius underwater laboratory off the coast of Florida to study how the diversity of seaweed-eating fish affects endangered coral reefs. The research mission, which began Sept. 13, may provide new information to help scientists protect and even restore damaged coral reefs in the Caribbean.

Cybersecurity Companies Boost Atlanta’s Industry Role

Winter/Spring 2011 Research Horizons Magazine — Georgia Tech cybersecurity faculty members are helping grow the cybersecurity industry by spinning off companies.

Powered by Seaweed: Polymer from Brown Algae May Improve Electrodes in Lithium-Ion Batteries and Allow Replacement of Harmful Solvents

September 8, 2011 — By looking to Mother Nature for solutions, researchers have identified a promising new binder material for lithium-ion battery electrodes that could not only boost energy storage, but also eliminate the use of toxic compounds now used in manufacturing the components.
