Prepare to prevent malicious AI use According to the University of Cambridge, 26 experts on the security implications of emerging technologies have jointly authored a ground-breaking report thereby sounding the alarm about the potential malicious use of artificial intelligence (AI) by rogue states, criminals, and terrorists. The report forecasts rapid growth in cyber-crime and the misuse of... » read more

Polariton graphs In a development that a team of researchers from the UK and Russia say could eventually surpass the capabilities of even the most powerful supercomputers, a type of ‘magic dust’ — which combines light and matter — can be used to solve complex problems. Hailing from the University of Cambridge, University of Southampton and Cardiff University in the UK and the Skolk... » read more

Potential anticancer drugs selected by neural network Moscow Institute of Physics and Technology researchers along with Mail.Ru Group, and Insilico Medicine have applied a generative neural network to create new pharmaceutical medicines with certain desired characteristics. A generative adversarial network (GAN) was developed and trained to "invent" new molecular structures in order to dram... » read more

Carbon Is So 2015 Researchers at MIT have created a supercapacitor that relies on a material other than carbon. This new class of materials, called metal-organic frameworks (MOFs), are a porous and sponge-like, according to MIT, tthereby providing a much larger surface area than carbon. As with most things electrical, more surface area is essential for superconductors. The problem the re... » read more

Shrinking perovskites Researchers from Imperial College London, Oxford University, Diamond Light Source, Pohang University of Science and Technology in Korea, and Rutgers University have discovered a material that can be chemically tailored to either expand or contract in a precise way and over a wide temperature range. This could lead to new composite materials that do not expand when heate... » read more

Photonic memories A team of researchers from Oxford University, the University of Münster, the Karlsruhe Institute of Technology, and the University of Exeter produced the first all-photonic nonvolatile memory chip. The new device uses the phase-change material Ge2Sb2Te5 (GST), used in rewritable CDs and DVDs, to store data. This material can be made to assume an amorphous state, like glass... » read more

Hybrid crystals for efficient LEDs A team from the University of Toronto combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team designed a way to embed strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Perovskites are a family of materials that can be easily manufactured from solution, a... » read more

Single material batteries Engineers at the University of Maryland created a battery made entirely out of a single material that, by incorporating the properties of both the electrodes and electrolyte, can both move electricity and store it. The reason the new battery is revolutionary is because it solves the problem of what happens at the interface between the electrolyte and the electrod... » read more

Making light work of snaps 'Superradiance', a phenomenon where a group of atoms charged up with energy act collectively to release a far more intense pulse of light than they would individually, is well-known to physicists. In theory the effect can be reversed to create a device that draws in light ultra-efficiently. This could be revolutionary for devices ranging from digital cameras to solar... » read more

Silicon oxide memories Thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional production methods, Rice University’s silicon oxide technology for high-density, next-generation computer memory is one step closer to mass production. Rice’s silicon oxide memories are a type of two-terminal, “resistive random-access memory” (RRAM) ... » read more
