LCLS Powers Chain Reaction of Light: A New Tool for X-ray Studies

Researchers have found a new way to probe molecules and atoms with an X-ray laser, setting off cascading bursts of light that reveal precise details of what is going on inside, which could allow scientists to see details of chemical reactions in a way not possible before.

Symmetry: The Universe's Earliest Moments

How is it possible to look at the earliest moments of the universe? Physicists have their ways—and what they find out will tell us a lot about how the universe works today and how it will unfold in the future.

Home Computers Discover Gamma-ray Pulsars

As volunteers for a project called Einstein@Home, citizen scientists unleashed the unused cycles of their home computers on data from the Large Area Telescope, the SLAC-operated main instrument of the Fermi Gamma-ray Space Telescope, and found four new pulsars.

Mock Data, Real Science

In scientific circles, “mock” is not always a four-letter word. To test that they’re interpreting their massive amounts of data correctly, astrophysicists create even more data: “mock” data. And while that may be counterintuitive at first, it actually makes a surprising amount of sense.

Will 2-D Tin be the Next Super Material?

A single layer of tin atoms could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate.
