University of Sussex academics have established a method of turbocharging desktop PCs to give them the same capability as supercomputers worth tens of millions of pounds. Dr James Knight and Prof Thomas Nowotny from the University of Sussex's School of Engineering and Informatics used the latest Graphical Processing Units (GPUs) to give a single desktop PC the capacity to … [Read more...] about Desktop PCs run simulations of mammals’ brains

A team from Nanyang Technological University, Singapore (NTU Singapore) has developed a portable device that produces high-resolution 3D images of human skin within 10 minutes. The team said the portable skin mapping (imaging) device could be used to assess the severity of skin conditions, such as eczema and psoriasis. 3D skin mapping could be useful to clinicians, as most … [Read more...] about Team develops portable device that creates 3D images of skin in 10 minutes

Researchers from Mayo Clinic and AliveCor Inc. have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death. This research has yielded a breakthrough in determining the health of the electrical recharging system in a patient's heart. The researchers determined that a smartphone-enabled mobile EKG … [Read more...] about Breakthrough in mobile determination of QT prolongation

Social media is increasingly used to spread fake news. The same problem can be found on the capital market -- criminals spread fake news about companies in order to manipulate share prices. Researchers at the Universities of Göttingen and Frankfurt and the Jožef Stefan Institute in Ljubljana have developed an approach that can recognise such fake news, even when the news … [Read more...] about Detecting fake news designed to manipulate stock markets: Researchers develop robust approach for detecting market manipulation

Imagine a rubber band that was capable of snapping itself many times over, or a small robot that could jump up a set of stairs propelled by nothing more than its own energy. Researchers at the University of Massachusetts Amherst have discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. The discovery may prove … [Read more...] about Researchers discover materials capable of self-propulsion: Research highlights how shape and environment can cause materials to move without motors or hands

Researchers from North Carolina State University and the University of Texas have developed and demonstrated a new approach for designing photonic devices. The advance allows them to control the direction and polarization of light from thin-film LEDs, paving the way for a new generation of virtual reality (VR) and augmented reality (AR) technologies. "This is a fundamentally … [Read more...] about Photonics research makes smaller, more efficient VR, augmented reality tech possible

Rice University engineers have discovered technology that could slash the cost of semiconductor electron sources, key components in devices ranging from night-vision goggles and low-light cameras to electron microscopes and particle accelerators. In an open-access Nature Communications paper, Rice researchers and collaborators at Los Alamos National Laboratory (LANL) describe … [Read more...] about Damatically lowering costs of semiconductor electron sources

A calculation so complex that it takes twenty years to complete on a powerful desktop computer can now be done in one hour on a regular laptop. Physicist Andreas Ekström at Chalmers University of Technology, together with international research colleagues, has designed a new method to calculate the properties of atomic nuclei incredibly quickly. The new approach is based on a … [Read more...] about Solving complex physics problems at lightning speed

Despite all the advances in consumer technology over the past decades, one component has remained frustratingly stagnant: the optical lens. Unlike electronic devices, which have gotten smaller and more efficient over the years, the design and underlying physics of today's optical lenses haven't changed much in about 3,000 years. This challenge has caused a bottleneck in the … [Read more...] about A metalens for virtual and augmented reality: Researchers develop a millimeter-size flat lens for VR and AR platforms

MIT researchers have developed a type of neural network that learns on the job, not just during its training phase. These flexible algorithms, dubbed "liquid" networks, change their underlying equations to continuously adapt to new data inputs. The advance could aid decision making based on data streams that change over time, including those involved in medical diagnosis and … [Read more...] about ‘Liquid’ machine-learning system adapts to changing conditions: The new type of neural network could aid decision making in autonomous driving and medical diagnosis
