Life may owe its start to complex organic molecules manufactured in the icy heart of an interstellar cloud
On the 30th anniversary of the first manned lunar landing, digital reproductions of the Apollo photographs show the moon as the astronauts saw it
A new generation of experiments promises to pin down more of the still uncertain internal structure of protons and neutrons
The obstacles to building practical fuel cells are numerous, but continued innovation and skillful engineering could make them competitive
Fuel cells can power cleaner buses and cars, but key engineering and economic obstacles will delay widespread adoption of the technology
In the past, stationary fuel cells were megawatt behemoths, designed for the electric utilities. Now they are being shrunk for homes and other modest applications
Batteries are cumbersome and expensive. Miniature fuel cells could supplant them in cellular phones, laptop computers, camcorders and other consumer products
