Cosmic Slurp: Researchers Predict Signs of Black Holes Swallowing Stars
Using a mix of theoretical and computer-based approaches, researchers are trying to predict the dynamics of events such as black holes devouring stars, a scenario also known as a "tidal disruption."
Neuromorphic Computing “Roadmap” Envisions Analog Path to Simulating Human Brain
Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer that mimics the brain's operation.
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.
