Astrophysicists at Lawrence Berkeley National Laboratory (Berkeley Lab) and the Institute of Cosmology and Gravitation at the University of Portsmouth in the U.K. say strongly lensed Type Ia supernovae could help resolve a discrepancy in measurements of the universe’s accelerating expansion.
Berkeley Lab and UC Berkeley scientists were part of a team that helped to decipher one of the most bizarre spectacles ever seen in the night sky: A supernova that refused to stop shining, remaining bright far longer than an ordinary stellar explosion. What caused the event is puzzling.
Scientists at Berkeley Lab will be sifting through loads of new data expected from the latest experimental run at CERN’s Large Hadron Collider.
It’s easy to form the mental image of a hacker hunched over a computer, probing a way to get your personal information, whether to sell it, acquire credit cards in your name or use your health insurance. It does happen, but University of New Mexico researchers, working with Steven Hofmeyr from Berkeley Lab, say it is not happening more frequently than it did a decade ago. Data breaches, in general, are not growing in size.
With the advent of new technology, scientific facilities are collecting data at increasing rates and higher resolution. However, making sense of this data is becoming a major bottleneck. To address these growing needs, the Department of Energy has announced approval of a grant of $10.5 million over three years to expand the Center for Advanced Mathematics for Energy Research Applications at Berkeley Lab.
A comprehensive understanding of complex nanostructures—like proteins and viruses—could lead to breakthroughs in some of the most challenging problems in biology and medicine. But because these objects are a thousand times smaller than the width of human hair, scientists can’t directly see into them to determine their shape and function.
Two researchers at Berkeley Lab were on the list of 44 recipients announced today as recipients of the Early Career Research Program award managed by the U.S. Department of Energy’s Office of Science.
When it comes to boiling water—or the phenomenon of applying heat to a liquid until it transitions to a gas—is there anything left for today’s scientists to study? The surprising answer is, yes, quite a bit. How the bubbles form at a surface, how they rise up and join together, what are the surface properties, what happens if the temperature increases slowly versus quickly—while these components might be understood experimentally, the mathematical models for the process of boiling are incomplete.
The Planck collaboration has released its first cosmological results, based on trillions of measurements of the cosmic microwave background. The results owe much to Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC), including tens of millions of hours of massively parallel processing, plus the expertise of physicists and computational scientists in the Computational Cosmology Center (C3) who generated a quarter of a million simulated maps of the Planck sky, essential to the analysis.
A computer model of fluid flow in shale takes kerogen inclusions into account for the first time, allowing realistic predictions of reservoir productivity.
