The USA has only two accelerators that can produce 10 billion electron-volt particle beams, and they're each about 1.9 miles (3 km) long. "We can now reach those energies in 10 cm (4 inches)," said ...

Scientists have directly measured the minuscule electron sharing that makes precious-metal catalysts so effective. Their new technique, IET, reveals how molecules bind and react on metal surfaces with ...
