The Internet Was Delivered to the Masses; Parallel Computing Is Not Far Behind

FengWuatsupercomputer.jpg

The groundwork for Virginia Tech’s Wu Feng’s big data research in a “cloud” began in the mid-2000s with a multi-institutional effort to identify missing gene annotations in genomes. Today, this work is being formalized and extended as part of an National Science Foundation/Microsoft Computing in the Cloud grant that seeks to commoditize biocomputing in the cloud.

Tattoo Biobatteries Produce Power From Sweat
 (Video)

In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers will report today at the 248th National Meeting & Exposition of the American Chemical Society that they have designed a sensor in the form of a temporary tattoo that can both monitor a person’s progress during exercise and produce power from their perspiration.

Could Hemp Nanosheets Topple Graphene for Making the Ideal Supercapacitor?


As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. They’re presenting their work, which a start-up company is working on scaling up, at the 248th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

Robotic-Assisted Ultrasound Imaging: From Trans-Atlantic Evaluation to Help in Day-to-Day Practice

WideTeleroboticultrasound.jpg

While in Germany, Partho P. Sengupta, MD, of Icahn School of Medicine at Mount Sinai used a computer to perform a robot-assisted trans-Atlantic ultrasound examination on a person in Boston. In another study Kurt Boman, MD, of Umeå University in Sweden in collaboration with Mount Sinai, showed how a cardiologist’s video e-consultation, coupled with a remote robot-assisted echocardiogram test, dramatically reduces the waiting time for a diagnosis faced by heart failure patients.
