A different type of 2-D semiconductor

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers have produced the first atomically thin 2-D sheets of organic-inorganic hybrid perovskites. These ionic materials exhibit optical properties not found in 2-D covalent semiconductors such as graphene, making them promising alternatives to silicon for future electronic devices.

New theory of stealth dark matter may explain universe's missing mass

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Lawrence Livermore scientists have come up with a new theory that may identify why dark matter has evaded direct detection in Earth-based experiments.

Mysterious neutrinos take the stage at SLAC

DOE/SLAC National Accelerator Laboratory

To find out more about the elusive particles and their potential links to cosmic evolution, invisible dark matter and matter's dominance over antimatter in the universe, the Department of Energy's SLAC National Accelerator Laboratory is taking on key roles in four neutrino experiments: EXO, DUNE, MicroBooNE and ICARUS.

CAMERA to develop computational mathematics for experimental facilities research

DOE/Lawrence Berkeley National Laboratory
Grant and Award Announcement

Department of Energy has announced approval of a joint ASCR-BES-supported grant of $10.5 million over three years to expand the Center for Advanced Mathematics for Energy Research Applications (CAMERA). CAMERA's mission is to develop fundamental mathematics and algorithms, delivered as data analysis software that can accelerate scientific discovery.

A new view of the content of Earth's core

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

There is more oxygen in the core of Earth than originally thought. Lawrence Livermore geologist Rick Ryerson and international colleagues discovered some new findings about Earth's core and mantle by considering their geophysical and geochemical signatures together.

Dirty, crusty meals fit for (long-dormant) microbes

DOE/Joint Genome Institute
Peer-Reviewed Publication

Deploying a set of tools he calls 'exometabolomics,' Trent Northen, a scientist at Lawrence Berkeley National Laboratory and the US Department of Energy Joint Genome Institute, and his team harnessed the analytical capabilities of the latest mass spectrometry techniques to quantitatively measure how individual microbes and the biocrust community transform complex mixtures of metabolites, in this case, from soil. The study published Sept. 22, 2015 in Nature Communications.

DESI, an ambitious probe of dark energy, achieves its next major milestone

DOE/Lawrence Berkeley National Laboratory
Business Announcement

The US Department of Energy has announced approval of Critical Decision 2 (CD-2), authorizing the scientific scope, schedule, and funding profile of DESI, the Dark Energy Spectroscopic Instrument, an exceptional apparatus designed to improve our understanding of the role of dark energy in the expansion history of the universe.

Roopali Kukreja wins 2015 Klein Award for X-ray work

DOE/SLAC National Accelerator Laboratory

Roopali Kukreja, a former researcher at the Department of Energy's SLAC National Accelerator Laboratory who received her Ph.D. in materials science at Stanford University last year, will be honored during a SLAC conference next month with the Melvin P. Klein Scientific Development Award for her X-ray studies of nanoscale magnetic and electrical properties of materials.

Making 3-D objects disappear

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley researchers have devised an ultra-thin invisibility 'skin' cloak that can conform to the shape of an object and conceal it from detection with visible light. Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.

Nanoelectronics could get a boost from carbon research

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Lawrence Livermore scientists have investigated a way to create linear chains of carbon atoms from laser-melted graphite. The material, called carbyne, could have a number of novel properties, including the ability to adjust the amount of electrical current traveling through a circuit, depending on the user's needs.
