Scientists discover 'chiral phonons' -- atomic rotations in a 2-D semiconductor crystal

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

A research team has found the first evidence that a shaking motion in the structure of an atomically thin material possesses a naturally occurring circular rotation that could become the building block for a new form of information technology and molecular-scale machines.

Magnetic trick triples the power of SLAC's X-ray laser

DOE/SLAC National Accelerator Laboratory

Scientists at the Department of Energy's SLAC National Accelerator Laboratory have discovered a way to triple the amount of power generated by the world's most powerful X-ray laser. The new technique, developed at SLAC's Linac Coherent Light Source (LCLS), will enable researchers to observe the atomic structure of molecules and ultrafast chemical processes that were previously undetectable at the atomic scale.

Gene enhancers are important despite apparent redundancy

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists answered a long-standing question about the role of enhancers. And by better linking the genomic complement of an organism with its expressed characteristics, their work offers new insights that further the growing field of systems biology, which seeks to gain a predictive understanding of living systems.

SLAC Scientists investigate how metal 3-D printing can avoid producing flawed parts

DOE/SLAC National Accelerator Laboratory

Scientists at the Department of Energy's SLAC National Accelerator Laboratory are using X-ray light to observe and understand how the process of making metal parts using three-dimensional (3-D) printing can leave flaws in the finished product -- and discover how those flaws can be prevented.

Applying machine learning to the universe's mysteries

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab physicists and their collaborators have demonstrated that computers are ready to tackle the universe's greatest mysteries -- they used neural networks to perform a deep dive into data simulating the subatomic particle soup that may have existed just microseconds after the big bang.

Berkeley lab researchers contribute to making blockchains even more robust

DOE/Lawrence Berkeley National Laboratory

In the last few years, researchers at Berkeley Lab, UC Davis and University of Stavanger in Norway have developed a new protocol, called BChain, which makes private blockchain even more robust. The researchers are also working with colleagues at Berkeley Lab and beyond to adapt this tool to support applications that are of strategic importance to the Department of Energy's Office of Science.

Networking, data experts design a better portal for scientific discovery

DOE/Lawrence Berkeley National Laboratory
Business Announcement

A team of networking experts from the Department of Energy's Energy Sciences Network (ESnet), with the Globus team from the University of Chicago and Argonne National Laboratory, have designed a new approach that makes data sharing faster, more reliable and more secure.

Silencing is golden: Scientists image molecules vital for gene regulation

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Lab scientists use cryo-electron microscopy to gain a deeper understanding of the structure of a regulatory complex. Their research could open up new possibilities for cancer therapies.

Scientists catch light squeezing and stretching next-gen data storage material

DOE/SLAC National Accelerator Laboratory

Scientists at the Department of Energy's SLAC National Accelerator Laboratory have seen for the first time how atoms in iron-platinum nanoparticles -- a next-generation material for magnetic data storage devices -- respond extremely rapidly to brief laser flashes. Understanding these fundamental motions could potentially lead to new ways of manipulating and controlling such devices with light.

X-ray experiments suggest high tunability of 2-D material

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Researchers used MAESTRO, an X-ray platform at Berkeley Lab, to zero in on signatures of exotic electronic behavior in a 2-D material. They found that the material may be highly tunable, with potential applications in spintronics and other emerging fields.
