Subscribe PHOTO: NGC 1453, a giant elliptical galaxy situated in the constellation Eridanus, was one of 63 galaxies used to calculate the expansion rate of the local universe. Last year, the MASSIVE survey team determined that the galaxy is located 166 million light years from Earth and has a black hole at its center with a mass nearly 3 billion times that of the sun.

Nanotechnology Now Home > Press > Instrument at BESSY II shows how light activates MoS2 layers to become catalysts A new instrument at BESSY II can be used to study molybdenum-sulfide thin films that are of interest as catalysts for solar hydrogen production. A light pulse triggers a phase transition from the semiconducting to the metallic phase and thus enhances the catalytic activity. CREDIT Martin Künsting /HZB Abstract: MoS2 thin films of superposed alternating layers of molybdenum and sul...

Berkeley Lab’s Advanced Light Source at sunset. (Credit: Thor Swift/Berkeley Lab) The U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) supports more than 10,000 jobs in the Bay Area and nearly 20,000 jobs across the country, according to a new economic impact study that underscores Berkeley Lab’s role as a major employer in the East Bay in addition to being a powerhouse of innovation. The study also determined that every federal dollar invested in Berkeley ...

Industrial Internet of Things Has Value But Presents Hurdles The Internet of Things (IoT) also has broad industrial applications. The Industrial Internet of Things (IIoT) goes far beyond a refrigerator alerting people to a shortage of butter. Connected machines managed by artificial intelligence automate manufacturing jobs, increase production speed, and enhance safety and security. Although large companies recognize the advantages presented by IIoT, the complexity of adopting the technology re...

A new study suggests that the presence of tau protein aggregates in anterior temporal regions of the brain could be used as a marker of early Alzheimer's disease progression.

It was a first demonstration of... view more  Credit: Chungnam National University COSMIC, a multipurpose X-ray instrument at Lawrence Berkeley National Laboratorys (Berkeley Labs) Advanced Light Source (ALS), has made headway in the scientific community since its launch less than 2 years ...

U.S. Can Run Primarily on Renewable Energy by 2050 For Cost of $1 Per Person Per Day—Says New Research Mar 2, 2021 Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, says a new study. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory, the University of San Francisco (USF), and Evolved Ene...

On-chip optical antennas remove data limits March 02, 2021 // By Jean-Pierre Joosting Latest research throws wide open the amount of data or information that can be simultaneously transmitted by a single light source. A new method of harnessing the properties of light waves that can radically increase the amount of data they carry has been discovered by researchers at the University of California, Berkeley. They demonstrated the emission of discrete twisting laser beam...
