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”
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
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
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
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
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.
