A New Filter to Better Map the Dark Universe

Photo illustration - Just as the wine glass distorts an image of the cosmic microwave background in this photo illustration, large objects like galaxy clusters and galaxies can similar distort this light to produce lensing effects. (Credit: Emmanuel Schaan and Simone Ferraro/Berkeley Lab)

The ‘Little’ Computer Cluster That Could

When Semiconductors Stick Together, Materials Go Quantum

Laser ‘Drill’ Sets a New World Record in Laser-Driven Electron Acceleration

Image - A snapshot of a plasma channel’s electron density profile (blue) formed inside a sapphire tube (gray) with the combination of an electrical discharge and an 8-nanosecond laser pulse (red, orange, yellow). This plasma channel was used to guide femtoseconds-long “driver” laser pulses from the BELLA petawatt laser system, which generated plasma waves and accelerated electrons to 8 billion electron volts in just 20 centimeters.

Preparing for a New Tool to Study the ‘Glue That Binds Us All’

Image - At left is a 1980s conception of the structure of the proton, which is a positively charged particle found in atomic nuclei. At right is our current understanding of the various subatomic particles – including quarks, antiquarks, and gluons – that make up the proton and contribute to a fundamental property known as spin.
