Electric eels deliver Taser-like shocks

The electric eel - the scaleless Amazonian fish that can deliver an electrical jolt strong enough to knock down a full-grown horse - possesses an electroshock system uncannily similar to a Taser.

Stanley Miller's forgotten experiments, analyzed

Stanley Miller, the chemist whose landmark experiment published in 1953 showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never analyzed. The first-ever ...

Unzipped nanotubes unlock potential for batteries

(Phys.org) —Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.

Toughened silicon sponges may make tenacious batteries

(Phys.org) -- Researchers at Rice University and Lockheed Martin reported this month that they've found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace ...

Mars rovers safe from lightning strikes, research finds

If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles are unlikely to generate big electrical storms or threaten the newly arrived exploration vehicles ...

New tractor beam has potential to tame lightning

Lightning never strikes twice, so the saying goes, but new technology may allow us to control where it hits the ground, reducing the risk of catastrophic bushfires.
