No-power Wi-Fi connectivity could fuel Internet of Things reality Posted: 04 Aug 2014 10:42 AM PDT Engineers have designed a new communication system that uses radio frequency signals as a power source and reuses existing Wi-Fi infrastructure to provide Internet connectivity to battery-free devices.

Extracting audio from visual information: Algorithm recovers speech from vibrations of a potato-chip bag filmed through soundproof glass Posted: 04 Aug 2014 07:05 AM PDT Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.

How 'biological spark plug' in biomolecular motors works Posted: 04 Aug 2014 07:01 AM PDT Using high-performance computers and quantum mechanical methods, researchers have simulated processes that reveal how the "biological spark plug" works in the biomolecular motors of cells. The investigations focused on the myosin protein, which, among other things, is responsible for muscle movement. The researchers' extensive simulations show how the release of energy is initiated in this complex motor.

Tool to better visualize, analyze human genomic data developed Posted: 03 Aug 2014 04:37 PM PDT A new, web-based tool that enables researchers to quickly and easily visualize and compare large amounts of genomic information resulting from high-throughput sequencing experiments has been developed by researchers. The free tool, called Epiviz, offers a major advantage over browsers currently available: Epiviz seamlessly integrates with the open-source Bioconductor analysis software widely used by genomic scientists, through its Epivizr Bioconductor package.
