The strength of a chemical bond between atoms is the fundamental basis for a molecule’s stability and reactivity.

Proteins are jittery things – continually moving, flopping around and waving their molecular arms.

By finding a clever way to use the Earth itself as a scientific instrument, members of a SLAC-led research team turned the Fermi Gamma-ray Space Telescope into a positron detector – and confirmed a startling discovery from 2009 that found...

Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe.

Cooks think of watched pots. Handymen grumble about drying paint.

Menlo Park, Calif. – Scientists have reached a crucial milestone that could lead to a new class of materials with useful electronic properties.

Are parallel universes real?

The great thing about SLAC’s Linac Coherent Light Source is that it churns out incredible volumes of data about things no one has ever seen before, such as snapshots of individual viruses.

A new x-ray microscopy technique that allows scientists to make images 60 times faster than before has been developed by an Australian research team including Garth Williams, who is now an instrument scientist at SLAC’s Linac Coherent Light Source.

Although materials scientists have theorized for years that a form of super-dense aluminum exists under the extreme pressures found inside a planet’s core, no one had ever actually seen it.
