A novel manufacturing method could make it practical to stack solar cells and convert more of the energy in sunlight into electricity.
If the cosmos is a numerical simulation, there ought to be clues in the spectrum of high energy cosmic rays, say theorists
Japanese researchers build a gun capable of stopping speakers in mid-sentence.
A 19th-century idea might lead to cleaner cars, larger-scale renewable energy.
