Study Reveals How Some High-Energy Particle ‘Jets’ Lose Energy

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have revealed how certain particle-jets lose energy as they traverse the unique form of nuclear matter created in these collisions. The results should help them learn about key transport properties of this hot particle soup, known as a quark-gluon plasma (QGP).

SLAC’s superconducting X-ray laser reaches operating temperature colder than outer space

Nestled 30 feet underground in Menlo Park, California, a half-mile-long stretch of tunnel is now colder than most of the universe. It houses a new superconducting particle accelerator, part of an upgrade project to the Linac Coherent Light Source (LCLS) X-ray free-electron laser at the Department of Energy’s SLAC National Accelerator Laboratory. 

Ultrafast ‘Camera’ Captures Hidden Behavior of Potential ‘Neuromorphic’ Material

Imagine a computer that can think as fast as the human brain while using very little energy. That’s the goal of scientists seeking to discover or develop “neuromorphic” materials that can send and process signals as easily as the brain’s neurons and synapses. In a paper just published scientists describe surprising new details about vanadium dioxide, one of the most promising neuromorphic materials.

UNH-led Atlantic Marine Energy Center Receives Nearly $10 Million From DOE

The new Atlantic Marine Energy Center (AMEC), led by the University of New Hampshire in partnership with several East Coast universities, has been awarded $9.7 million over four years from the U.S. Department of Energy (DOE). The center will focus on research and development to address ongoing needs for sustainable renewable ocean energy. It will be one of only four National Marine Renewable Energy Centers (NMREC) in the country.

Scientists ID Enzyme for Making Key Industrial Chemical in Plants

Scientists studying the biochemistry of plant cell walls have identified an enzyme that could turn woody poplar trees into a source for producing a major industrial chemical. The research, just published in Nature Plants, could lead to a new sustainable pathway for making “p-hydroxybenzoic acid,” a chemical building block currently derived from fossil fuels, in plant biomass.

Collisions of Light Produce Matter/Antimatter from Pure Energy

Scientists studying particle collisions at the Relativistic Heavy Ion Collider have produced definitive evidence for two physics phenomena predicted more than 80 years ago: that matter/antimatter can be generated directly from collisions of photons and that a magnetic field can bend polarized light along different paths in a vacuum.

Tantalizing Signs of Phase-change ‘Turbulence’ in RHIC Collisions

A new analysis of collisions conducted at different energies at the Relativistic Heavy Ion Collider (RHIC) shows tantalizing signs of a critical point—a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from one phase to another. The findings will help physicists map out details of these nuclear phase changes to better understand the evolution of the universe and the conditions in the cores of neutron stars.

This Anti-COVID Mask Breaks the Mold

To address PPE shortages during the pandemic, scientists at Berkeley Lab and UC Berkeley are developing a rechargeable, reusable, anti-COVID N95 mask and a 3D-printable silicon-cast mask mold.
