Superconducting X-ray laser takes shape in Silicon Valley

An area known for high-tech gadgets and innovation will soon be home to an advanced superconducting X-ray laser that stretches 3 miles in length, built by a collaboration of national laboratories. On January 19, the first section of the machine's new accelerator arrived by truck at SLAC National Accelerator Laboratory in Menlo Park after a cross-country journey that began in Batavia, Illinois, at Fermi National Accelerator Laboratory.

Team takes a deep look at memristors

In the race to build a computer that mimics the massive computational power of the human brain, researchers are increasingly turning to memristors, which can vary their electrical resistance based on the memory of past activity. Scientists at the National Institute of Standards and Technology (NIST) have now unveiled the long-mysterious inner workings of these semiconductor elements, which can act like the short-term memory of nerve cells.

NASA Seeks Participants Interested in Learning to Build Rocket Payloads

NASA is seeking university and community college students and instructors interested in developing science payloads for space flight to participate in the eleventh annual RockOn! workshop June 16 – 21 at its Wallops Flight Facility in Virginia.

Smartphones come in handy for the rare cosmic particles search

Researchers from the Laboratory of Methods for Big Data Analysis (LAMBDA) at the Higher School of Economics have improved their method of analyzing ultra-high energy cosmic rays (UHECR) with the use of mobile phones. The work has been carried out as part of the CRAYFIS experiment and the results were presented at the 22nd International Conference on Computing in High Energy and Nuclear Physics.

Mobility patterns influence the spread and containment of an epidemic

Contrary to expectations, recurring mobility between different cities or districts of a large city (for example, work-home commutes) can minimise the spread of an epidemic. This is the finding of research carried out by researchers from the Universitat Rovira i Virgili (Àlex Arenas) and the University of Zaragoza (Jesús Gómez and David Soriano) and which has just been published in the journal Nature Physics.

Continuous Electron Beam Accelerator Facility delivers beam to all four of its experimental areas simultaneously

Just months after completing a nine-year construction project to upgrade its research capabilities, the Department of Energy's Thomas Jefferson National Accelerator Facility has delivered its next technological success: For the first time, the Continuous Electron Beam Accelerator Facility (CEBAF) has delivered electron beams simultaneously to all four experimental halls. This achievement maximizes the amount of research that can be accomplished during run times and paves the way for the next era of ground-breaking experiments at the lab.

NASA Announces Updated Crew Assignments for Space Station Missions

NASA is announcing an addition to the NASA lineup for upcoming launches, and making changes to some assignments for International Space Station missions in 2018.

New input for quantum simulations

Researchers have devised new methods to create interesting input states for quantum computations and simulations. The new methods can be used to simulate certain electronic systems to arbitrarily high accuracy.

Long-Term Warming Trend Continued in 2017: NASA, NOAA

Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.

Coupling experiments to theory to build a better battery

Researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles.
