Seismic Resistance: Model Analyzes Shape-Memory Alloys for Use in Earthquake-Resistant Structures

February 9, 2012 — Recent earthquake damage has exposed the vulnerability of existing structures to strong ground movement. At Georgia Tech, researchers are analyzing shape-memory alloys for their potential use in constructing seismic-resistant structures.

Storm Studies: Low-Cost Instrument Developed by High School Students Could Aid Severe Weather Research

February 7, 2012 — Under the guidance of Georgia Tech researchers, a group of high school students has designed, built and tested a low-cost version of a device that monitors the buildup of electrical charge in clouds. A network of such devices, known as field mills, could be used to learn more about the lightning that is part of severe weather – while providing real-world science and engineering experience for the students.

Researchers Show How New Viruses Evolve, and in Some Cases, Become Deadly

January 26, 2012 — In the current issue of the journal Science, researchers demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations.

Heart Valve Geometry: Non-Invasive Measurements of Tricuspid Valve Anatomy Can Predict Severity of Valve Leakage

January 18, 2012 — A new study finds that the anatomy of the heart’s tricuspid valve can be used to predict the severity of leakage in the valve, which is a condition called tricuspid regurgitation.

Complex Systems: Georgia Tech Research Institute (GTRI) Receives $1.5 Million to Create Online Collaborative Vehicle Design Capability

January 17, 2012 — The Georgia Tech Research Institute (GTRI) has received a $1.5 million contract to produce an online environment that would let multiple design teams work together to develop new military vehicles. The VehicleForge project’s goal is to create a secure central website and other web-based tools and methods that would facilitate such collaborative development.

Bacterial Infections: New Laboratory Method Uses Mass Spectrometry to Rapidly Detect Staph Infections

January 12, 2012 — Georgia Tech and CDC researchers have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. The test uses mass spectrometry to quantify the number of Staphylococcus aureus organisms in a large number of samples in just a few hours.

Microneedle Injection: Startup Receives $4 Million to Develop Drug Delivery Targeted to the Back of the Eye

January 5, 2012 — Technology developed by researchers at the Georgia Institute of Technology and Emory University for delivering drugs and other therapeutics to specific locations in the eye provides the foundation for a startup company that has received a $4 million venture capital investment.

Concerning Access: Survey Reveals Scientists Have Trouble Accessing Human Embryonic Stem Cell Lines

December 12, 2011 — A survey of more than 200 human embryonic stem cell researchers in the United States found that nearly four in ten researchers have faced excessive delay in acquiring a human embryonic stem cell line and that more than one-quarter were unable to acquire a line they wanted to study.

Repairing DNA: Study Identifies Mechanisms Cells Use to Remove Bits of RNA from DNA Strands

December 4, 2011 — When RNA component units called ribonucleotides become embedded in genomic DNA, they can cause problems for cells, but not much is known about the fate of these ribonucleotides. A new study identifies two mechanisms cells use to recognize and remove ribonucleotides embedded in genomic DNA.

MRS Medal: Regents’ Professor Zhong Lin Wang Receives Recognition for New Science and Innovative Technology from Zinc Oxide Nanostructures

December 1, 2011 — Regents’ professor Zhong Lin Wang has received a 2011 Materials Research Society Medal for his contributions in the discovery, controlled synthesis, and fundamental understanding of zinc oxide nanowires and nanobelts, and the design and fabrication of novel, nanowire-based nanosensors, piezotronic devices and nanogenerators for energy harvesting.
