Noninvasive Brain Imaging Shows Readiness of Trainees To Perform Operations

Study led by Rensselaer Polytechnic Institute faculty and graduate student shows that surgeons who trained on simulator had higher level of cortical activation and faster times for cutting tasks. While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR.

Voice impersonators can fool speaker recognition systems

Skilful voice impersonators are able to fool state-of-the-art speaker recognition systems, as these systems generally aren’t efficient yet in recognising voice modifications, according to new research from the University of Eastern Finland. The vulnerability of speaker recognition systems poses significant security concerns.

New quantum materials offer novel route to 3D electronic devices

Researchers have shown how the principles of general relativity open the door to novel electronic applications such as a three-dimensional electron lens and electronic invisibility devices. In a new study funded by the Academy of Finland, Aalto University researchers Alex Westström and Teemu Ojanen propose a method to go beyond special relativity and simulate Einstein’s theory of general relativity in inhomogeneous Weyl semimetals.

Machine Learning Detects Marketing and Sale of Opioids on Twitter

Using advanced machine learning, a cross disciplinary team of University of California San Diego researchers developed technology that mined Twitter to identify entities illegally selling prescription opioids online. Between June and November 2015, some 619,937 tweets containing the keywords codeine, Percocet, fentanyl, Vicodin, Oxycontin, oxycodone and hydrocodone were collected.

Band Gaps, Made to Order

Engineers create atomically thin superlattice materials with precision. Control is a constant challenge for materials scientists, who are always seeking the perfect material — and the perfect way of treating it — to induce exactly the right electronic or optical activity required for a given application.

Slowing the clockwork

Progress on the way to smart nanomachines: LMU chemists have modified the synthesis of a molecular motor so as to reduce the speed of its light-driven rotation, thus permitting the researchers to analyze the mechanism of motion in complete detail.

Artificial intelligence for obtaining chemical fingerprints

Neural networks carry out chemical simulations in record time. Researchers at the Universities of Vienna and Göttingen have succeeded in developing a method for predicting molecular infrared spectra based on artificial intelligence. These chemical “fingerprints” could only be simulated by common prediction techniques for small molecules in high quality. With the help of the new technology, which is based on neuronal networks similar to the human brain and is therefore capable of learning, the team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna was able to carry out simulations that were previously not possible.

Scientists move step towards “holy grail” of computing by creating brain-like photonic microchips

Scientists have made a crucial step towards unlocking the “holy grail” of computing – microchips that mimic the way the human brain works to store and process information. A research team, including Professor C. David Wright from the University of Exeter, have made a pioneering breakthrough by developing photonic computer chips – that use light rather than electricity – that imitate the way the brain’s synapses operate.

New type of supercomputer could be based on ‘magic dust’ combination of light and matter

A team of researchers from the UK and Russia have successfully demonstrated that a type of ‘magic dust’ which combines light and matter can be used to solve complex problems and could eventually surpass the capabilities of even the most powerful supercomputers. The researchers have used quantum particles known as polaritons – which are half light and half matter – to act as a type of ‘beacon’ showing the way to the simplest solution to complex problems.

IBM Research and UC San Diego Collaborate to Advance the Use of Artificial Intelligence for Healthy Living

UC San Diego is the first West Coast university to join the IBM Cognitive Horizons Network. IBM (NYSE: IBM) and the University of California San Diego have announced a multi-year project to enhance quality of life and independence for aging populations through the new Artificial Intelligence for Healthy Living Center (AIHL)), located on the campus of UC San Diego. The groundbreaking center will bring together the technology, artificial intelligence and life sciences knowledge of IBM and UC San Diego to promote critical research and applications in two thematic areas: Healthy Aging and the Human Microbiome.
