Bouncing neutrons rule out some theories of the exotic origins of dark energy. Read the associated APS Physics Viewpoint.
Rapid imaging technique adapted from medical applications shows promise in detection of nuclear materials.
With soap, water, graphite and the whirl of a blender’s blades, researchers can serve up big batches of graphene, a material that shows promise for use in myriad high-tech applications.
Invoking dark matter as a means to explain the excess of positrons observed last year by the Alpha Magnetic Spectrometer (AMS-02) experiment might not be necessary, according to physicists in Europe. Instead, they say, the entire dataset...
