Virtual review of cancer clinical trial treatment options quicker than conventional method

Virtual Reality - Science Daily - 9 October 2019 - 1:24pm
Using virtual, cloud-based, interconnected computing techniques applied to 51,000 variables, researchers reduced the time needed to assess a cancer patient's tumor profile and suitability for clinical trials from 14 to 4 days. This method also increased two-fold, over a four-year period, the number of cases that could be assessed compared to conventional methods.

Virtual human hand simulation holds promise for prosthetics

Virtual Reality - Science Daily - 26 September 2019 - 1:13pm
Animating human hands has long been considered one of the most challenging problems in computer graphics. That's because it has been impossible to capture the internal movement of the hand in motion -- until now. Using magnetic resonance imaging (MRI) and a technique inspired by the visual effects industry, researchers have developed the world's most realistic model of the human hand's musculoskeletal system in motion. Applications include computer graphics, prosthetics, medical education, robotics, virtual reality.

Scientists finally find superconductivity in place they have been looking for decades

Virtual Reality - Science Daily - 26 September 2019 - 11:50am
Scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern - as if hopping to the atom diagonally across the street rather than to the one next door.

Evolution of learning is key to better artificial intelligence

Virtual Reality - Science Daily - 20 September 2019 - 9:46am
Since "2001: A Space Odyssey," people have wondered: could machines like HAL 9000 eventually exist that can process information with human-like intelligence? Researchers say that true, human-level intelligence remains a long way off, but a new article explores how computers could begin to evolve learning in the same way as natural organisms did -- with implications for many fields, including artificial intelligence.
