Holographic movies, like the one R2D2 projected of Princess Leia in "Star Wars: A New Hope," have long been the province of science fiction, but for most of us, the extent of our experience with holograms may be the dime-sized ...

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Mollusc shells inspire super-glass

Engineers intrigued by the toughness of mollusc shells, which are composed of brittle minerals, have found inspiration in their structure to make glass 200 times stronger than a standard pane.
