Physical Review Letters Lawrence Livermore scientists 1 step closer to mimicking gamma-ray bursts
Using ever more energetic lasers, Lawrence Livermore researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.

Science NuSTAR provides explosive evidence for supernova asymmetry
New results from the NASA NuSTAR telescope show that a supernova close to our galaxy experienced a single-sided explosion. A team of scientists including Lawrence Livermore National Laboratory researchers found that X-ray emissions taken with the Nuclear Spectroscopic Telescope Array show that the Supernova 1987A explosion was highly asymmetric. The results appear in the May 8 edition of the journal, Science.

Nature Climate Change Soil organic matter susceptible to climate change
Soil organic matter, long thought to be a semi-permanent storehouse for ancient carbon, may be much more vulnerable to climate change than previously thought.

Nature Geoscience A change in thought on Earth's core formation
Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.

Science Giving shape to black holes' intense winds
By looking at the speed of ambient gas spewing out from a well-known quasar, astronomers are gaining insight into how black holes and their host galaxies might have evolved at the same time.
Public Release: 9-Feb-2015 DARPA taps lab to help restore sense of touch to amputees
The Defense Advanced Research Projects Agency recently selected Lawrence Livermore National Laboratory to join a collaborative research team that intends to build the world's first neural system to enable naturalistic feeling and movements in prosthetic hands.

Nature Communications Sodium carbonate capsules used to capture carbon safely
The team developed a new type of carbon capture media composed of core-shell microcapsules, which consist of a highly permeable polymer shell and a fluid (made up of sodium carbonate solution) that reacts with and absorbs carbon dioxide. Sodium carbonate is typically known as the main ingredient in baking soda. The capsules keep the liquid contained inside the core, and allow the CO2 gas to pass back and forth through the capsule shell.
Public Release: 14-Jan-2015 Ultra-realistic radiation detection training without using radioactive materials
Lawrence Livermore National Laboratory researchers have solved the problem by developing a new technology that provides realistic radiation detection training by directly injecting simulated radiation signals into the analog amplifier of the real detectors used by first responders and inspectors. The Spectroscopic Injection Pulser will yield training results that are indistinguishable by detection instruments from actual radiation sources.

Geophysical Research Letters Small volcanic eruptions partly explain 'warming hiatus'
Scientists have long known that volcanoes cool the atmosphere because of the sulfur dioxide that is expelled during eruptions. Droplets of sulfuric acid that form when the gas combines with oxygen in the upper atmosphere can persist for many months, reflecting sunlight away from Earth and lowering temperatures at the surface and in the lower atmosphere.
Public Release: 7-Jan-2015 Tracing tainted food back to its source within an hour
Lawrence Livermore National Laboratory researchers, in collaboration with the start-up DNATrek, have developed a cost-effective and highly efficient method to accurately trace contaminated food back to its source. Lawrence Livermore originally designed the technology, known as DNATrax, to safely track indoor and outdoor airflow patterns.

Science X-ray laser acts as tool to track life's chemistry
An international research team that includes researchers from Lawrence Livermore National Laboratory has captured the highest-resolution protein snapshots ever taken with an X-ray laser, revealing how a key protein in a photosynthetic bacterium changes shape when hit by light.

Environmental Research Letters Livermore scientists show salinity counts when it comes to sea level
Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.
Public Release: 30-Oct-2014 Lawrence Livermore develops infrared camera system to view tokamak from the inside
Lawrence Livermore National Laboratory researchers, in collaboration with General Atomics and the University of Arizona, have developed an infrared and visible camera viewing system that's able to produce wide-angle, tangential views of full poloidal (north-south direction of the magnetic field) cross-sections inside the tokamak. The camera's images provide researchers with data about the interior conditions of the DIII-D, which was built under contract for the Department of Energy. DOE provides funding for its operation.

Nature Tiny carbon nanotube pores make big impact
A team led by the Lawrence Livermore scientists has created a new kind of ion channel based on short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA.

PLOS ONE Supercomputers link proteins to drug side effects
New medications created by pharmaceutical companies have helped millions of Americans alleviate pain and suffering from their medical conditions. However, the drug creation process often misses many side effects that kill at least 100,000 patients a year.

Nature Dead star shines on
A supernova is the cataclysmic death of a star, but it seems its remnants shine on. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
