Researchers have demonstrated bio-inspired devices that accelerate routes to neuromorphic, or brain-like, computing. Their discovery could support the emergence of computing networks modeled on biology for a sensory approach to machine learning.
Read moreFirst demonstration of one petabit per second network node
Computer scientists have demonstrated the first large-scale optical switching testbed capable of handling 1 Petabit per second optical signals. This demonstration made use of state-of-the-art large-scale and low-loss optical switches based on MEMS technology, three types of next-generation spatial-division multiplexing fibers, and included data rates from 10 Terabit per second to 1 Petabit per second. This is a major step forward towards practical petabit-class backbone networks.

In quantum computing, as in team building, a little diversity can help get the job done better, computer scientists have discovered.
Read moreThat new yarn? Wearable, washable textile devices are possible with MXene-coated yarns
Researchers have figured out how to add more conductivity into functional fabric devices, by coating yarns with a 2-dimensional carbon-based material called MXene, to make conductive threads. The group has developed a dip-coating method, similar to the dyeing process, that can produce a conductive yarn strong enough for use in industrial knitting machines and durable enough to make it through wash cycles without degrading.
Read moreFuture intent: Would you let an automated car do the driving?
Researchers have surveyed more than 2000 drivers across Australia, France and Sweden for two separate studies investigating what people think about travelling in automated cars. The first international study found French drivers were more likely to one day buy an automated car than drivers in Australia or Sweden. The second study surveyed local Queensland drivers and identified what they saw as the pros and cons of letting a car drive itself.
Read moreThe fast dance of electron spins
Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role. Researchers succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes.

The cryptocurrency Bitcoin is limited by its astronomical electricity consumption and outsized carbon footprint. A nearly zero-energy alternative sounds too good to be true, but as a professor explains, it all comes down to our understanding of what makes transactions secure.
