Topping Off a Telescope with New Tools to Explore Dark Energy

Key components for the sky-mapping Dark Energy Spectroscopic Instrument, weighing about 12 tons, were hoisted atop the Mayall Telescope at Kitt Peak National Observatory near Tucson, Arizona, and bolted into place last week, marking a major project milestone.

How Berkeley Lab is Advancing Microelectronics

In collaboration with scientists at Intel Corp., Berkeley Lab scientist Ramamoorthy Ramesh proposes a new memory in logic device for replacing or augmenting conventional transistors.

Q&A: How to Protect Yourself and Your Family From Wildfire Smoke

Berkeley Lab indoor air experts Brett Singer and Woody Delp advise: stay indoors, consider a mask, limit activities, use air filtration systems, or even build your own.

A Next Step for GRETA: A Better Gamma-Ray Detector

A new high-resolution gamma-ray detector system – designed to reveal new details about the structure and inner workings of atomic nuclei, and to elevate our understanding of matter and the stellar creation of elements – has passed an important project milestone.

Expert Q&A: Safeguarding the Nation’s Energy Infrastructure

In recognition of National Cybersecurity Awareness Month, cybersecurity expert Sean Peisert of Berkeley Lab discusses new methods that have the potential to keep our energy infrastructure safe from a cyberattack.

VIDEO: 5,000 Robots Merge to Map the Universe in 3D

How do you create the largest 3D map of the universe? It’s as easy as teaching 5,000 robots how to “dance.” DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by automatically swiveling fiber-optic positioners (the robots) to point at them and gather their light. In creating this detailed map, scientists hope to learn more about dark energy, which is driving the accelerating expansion of the universe.

How Drought and Other Extremes Impact Water Pollution

One in 10 Americans depends on the Colorado River for bathing and drinking. Last fall’s record-high temperatures reduced Colorado snowpack in winter 2018 to 66 percent of normal, sparking concern over water shortages downstream and leaving water managers fearful of a repeat. Berkeley Lab hydrological science expert Bhavna Arora explains how unseasonably warm weather and drought can affect water quality.

Ancient Pigment Can Boost Energy Efficiency

Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then emits light in the near-infrared range. Now a team led by researchers at Lawrence Berkeley National Laboratory has confirmed the pigment’s fluorescence can be 10 times stronger than previously thought.

Infrared Beams Show Cell Types in a Different Light

By shining highly focused infrared light on living cells, scientists at Berkeley Lab hope to unmask individual cell identities, and to diagnose whether the cells are diseased or healthy.

American Physical Society Publishes 60th Anniversary Edition of the Review of Particle Physics

The latest edition of the Review of Particle Physics, a go-to resource for particle physicists published Aug. 17 in the American Physical Society’s Physical Review D journal, marks the 60th anniversary of the founding of the Berkeley Lab-based Particle Data Group that produces the Review.
