Quantum networks can detect eavesdroppers and resist hacking at levels unrivaled by any classical networks today. Yet any expensive, specialized technologies that quantum networks require could still limit their appeal to telecom and other network operators today. Now researchers at Toshiba and their colleagues reveal that quantum communications are possible across more than 250 kilometers using existing commercial telecommunication infrastructure.

The lithium-ion battery can heal itself after being cut in halfBy Charles Q. ChoiA new lithium-ion battery can not only withstand stretching and twisting, but can get stabbed with needles and cut in half with razor blades—and then heal itself to continue providing power to a device. Wearable electronics, soft robots, and other devices could benefit from soft, stretchable lithium-ion batteries.

Twenty mouse models of autism can be sorted into two subtypes based on functional connectivity across the entire brain, a new preprint reports. The subtypes reflect changes in different molecular pathways and map on to nearly one-quarter of autistic people represented in a large dataset.

A microchip with nearly 6,000 transistors, each only three atoms thick, is the most complex microprocessor made from a two-dimensional material to date, scientists in China say. The new device was made using the semiconductor molybdenum disulfide, which consists of a sheet of molybdenum atoms sandwiched between two layers of sulfur atoms. Scientists hope 2D materials such as molybdenum disulfide will allow Moore’s Law to continue once it becomes impossible to make further progress using silicon.
