When Hawthorne, Calif.-based startup Epirus decided to test a new electronic weapon last winter, it filed an application with the Federal Communications Commission (FCC). It wanted to test its high power microwave device in the California desert east of Palm Springs, about three miles from a small airport and the busy I-10 interstate. The unnamed […]
There’s a reason luggage on an airplane isn’t supposed to contain lithium-ion batteries—they have a tendency to explode into flames. That’s the same reason recreational vehicle manufacturers are embracing lithium iron phosphate, a battery technology with a lower energy density than lithium-ion, but without the fire risk, trading off capacity for safety. Nanom (previously Greenvolt), a startup based […]

The folks at DeepMind are pushing their methods one step further toward the dream of a machine that learns on its own, the way a child does. The London-based company, a subsidiary of Alphabet, is officially publishing the research today, in Nature, although it tipped its hand back in November with a preprint in ArXiv. Only now, though, are the implications becoming […]
Photo-illustration: NASA Atoms for Propulsion: Rockets powered by nuclear fission or fusion are now vying to become the preferred (and faster) means of traveling the solar system. For all the controversy they stir up on Earth, nuclear reactors can produce the energy and propulsion needed to rapidly take large spacecraft to Mars and, if desired, […]
