New nanostructure for batteries keeps going and going

(Phys.org) -- For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge ...

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.

First direct evidence of lightning on Mars detected

For the first time, direct evidence of lightning has been detected on Mars, say University of Michigan researchers who found signs of electrical discharges during dust storms on the Red Planet.

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 ...

Methane on Mars may be result of electrification of dust-devils

Methane on Mars has long perplexed scientists; the short-lived gas has been measured in surprising quantities in Mars' atmosphere over several seasons, sometimes in fairly large plumes. Scientists have taken this to be evidence ...
