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 ...

Cause of cathode degradation identified for nickel-rich materials

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for ...

The cosmic start of lightning

Even though lightning is a common phenomenon, the exact mechanism triggering a lightning discharge remains elusive. Scientists at the Dutch national research institute for mathematics CWI, the University of Groningen and ...
