Take a glass thread a thousand times thinner than a human hair. Use it as a wire between two metals. Hit it with a laser pulse that lasts a millionth of a billionth of a second.

Remarkable things happen.

The glass-like material is transformed ever so briefly into something akin to a metal. And the laser generates a burst of electrical current across this tiny electrical circuit. It does so far faster than any traditional way of producing electricity and in the absence of an applied voltage. Further, the direction and magnitude of the current can be controlled simply by varying the shape of the laser—by changing its phase.

A group of physicists are questioning our understanding of how quarks — a type of elementary particle — arrange themselves under extreme conditions. And their quest is revealing that elements beyond the edge of the periodic table might be fair weirder than we thought.

Deep in the depths of the periodic table there are monsters made of a unique arrangement of subatomic particles. As far as elements go, they come no bigger than oganesson – a behemoth that contains 118 protons and has an atomic mass of just under 300.

That’s not to say protons and neutrons can’t be arranged into even bigger clumps and still remain somewhat stable for longer than an eye blink. But for all practical purposes, nobody has discovered it yet.

We don’t actually have a lot to be afraid of when it comes to asteroids. Sure, they might come pretty close from time to time, but they tend to buzz harmlessly by — after all, Earth is a pretty tiny target in the vastness of space.

That doesn’t mean we shouldn’t be prepared, though — and NASA, along with several other US federal agencies, has been putting together a contingency plan.

They’ve called the collective the Interagency Working Group for Detecting and Mitigating the Impact of Earth-bound Near-Earth Objects, or DAMIEN, which isn’t ominous at all, and released a 20-page document that outlines the asteroid — or near-Earth object (NEO) — plans for the next decade.
