Fish From Acidic Ocean Waters Less Able to Smell Predators

April 14, 2014 – Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.

Self-Assembled Silver Superlattices Create Molecular Machines with Hydrogen-Bond “Hinges” and Moving “Gears”

April 6, 2014 — A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.

Heat-Conducting Polymer Cools Hot Electronic Devices at 200 Degrees C

March 30, 2014 — By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer — operating at temperatures of up to 200 degrees Celsius.

Engineered Bacteria Produce Biofuel Alternative for High-Energy Rocket Fuel

March 26, 2014 — Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications.

Robotic Arm Probes Chemistry of 3-D Objects by Mass Spectrometry

March 26, 2014 – A new robotic system at Georgia Tech’s Center for Chemical Evolution could soon let scientists better simulate and analyze the chemical reactions of early Earth on the surface of real rocks to further test the theory that catalytic minerals on a meteorite’s surface could have jump-started life’s first chemical reactions.

Microfluidic Device With Artificial Arteries Measures Drugs’ Influence on Blood Clotting

March 24, 2014 – A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.

OneBusAway App Now Tracks MARTA Trains in Real Time

March 5, 2014 – The mobile app OneBusAway, which tracks public transportation in real time, now includes arrival times for MARTA trains in addition to the MARTA buses and Georgia Tech shuttles already featured in the app.

Self-Administration of Flu Vaccine with a Patch May be Feasible, Study Suggests

February 26, 2014 — The annual ritual of visiting a doctor’s office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine. The research, which involved nearly 100 people recruited in the metropolitan Atlanta area, found that test subjects could successfully apply a prototype vaccine patch to themselves.

Single Chip Device to Provide Real-Time 3-D Images from Inside the Heart and Blood Vessels

February 18, 2014 — Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart.

Silicon-Germanium Chip Sets New Speed Record

February 18, 2014 — A research collaboration has demonstrated the world’s fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
