Harnessing Error-Prone Chips

Harnessing Error-Prone Chips

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption.   With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. [...]

Gold Nanoparticles Confine Light On Nanoscale

Gold Nanoparticles Confine Light On Nanoscale

A multidisciplinary team at the Centre d’Elaboration de Matériaux et d’Etudes Structurales (CEMES, CNRS), working in collaboration with physicists in Singapore and chemists in Bristol (UK), have shown that crystalline gold nanoparticles aligned and then fused into long chains can be used to confine light energy down to the nanometer scale while allowing its long-range [...]

Computers: Powerful Allies in Fight Against AIDS

Computers: Powerful Allies in Fight Against AIDS

Effective treatment of HIV-virus is a race against time: Many of the drugs that have been potent killers of HIV-virus, have today lost their power, because the virus has become resistant to them. As a result science must constantly develop new drugs that can attack the virus in new ways.   Now researchers from the [...]

Moving Silicon Atoms in Graphene

Moving Silicon Atoms in Graphene

Richard Feynman famously posed the question in 1959: is it possible to see and manipulate individual atoms in materials? For a time his vision seemed more science fiction than science, but starting with groundbreaking experiments in the late 1980s and more recent developments in electron microscopy instrumentation it has become scientific reality. However, damage caused [...]

Algorithm Lets Drones Monitor Their Own Health

Algorithm Lets Drones Monitor Their Own Health

In the near future, the package that you ordered online may be deposited at your doorstep by a drone: Last December, online retailer Amazon announced plans to explore drone-based delivery, suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order.   To ensure [...]

Can Our Computers Get Smaller, More Powerful?

Can Our Computers Get Smaller, More Powerful?

From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment and governance while shrinking to become ubiquitous handheld portals to the world.   This progress has been driven by the industry’s ability to continually innovate [...]

Robots Learn Faster, Better With Online Helpers

Robots Learn Faster, Better With Online Helpers

Sometimes it takes a village to teach a robot. University of Washington computer scientists have shown that crowdsourcing can be a quick and effective way to teach a robot how to complete tasks. Instead of learning from just one human, robots could one day query the larger online community, asking for instructions or input on [...]

Another Clue in Hunt for Dark Matter

Another Clue in Hunt for Dark Matter

The hunt for dark matter has taken another step forward thanks to new supercomputer simulations showing the evolution of our “local Universe” from the Big Bang to the present day.   Physicists at Durham University, who are leading the research, say their simulations could improve understanding of dark matter, a mysterious substance believed to make [...]

Hunt for ET Life Gets Big Methane Boost

Hunt for ET Life Gets Big Methane Boost

A powerful new model to detect life on planets outside of our solar system, more accurately than ever before, has been developed by UCL (University College London) researchers.   The new model focuses on methane, the simplest organic molecule, widely acknowledged to be a sign of potential life. Researchers from UCL and the University of [...]

Computer Program to Teach Itself Everything?

Computer Program to Teach Itself Everything?

In today’s digitally driven world, access to information appears limitless. But when you have something specific in mind that you don’t know, like the name of that niche kitchen tool you saw at a friend’s house, it can be surprisingly hard to sift through the volume of information online and know how to search for [...]
