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.
Public Release: 7-Oct-2014 Bio researchers receive patent to fight superbugs
Superbugs, antibiotic-resistant bacteria, have been on the rise since antibiotics were first introduced 80 years ago. That's because these germ-fighting agents have lost their punch from being overprescribed and misused, allowing bacteria pathogens to develop immunities against them.

Nature Peering into giant planets from in and out of this world
Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system.
Public Release: 9-Jul-2014 DARPA selects Lawrence Livermore to develop world's first neural device to restore memory
The Department of Defense's Defense Advanced Research Projects Agency (DARPA) awarded Lawrence Livermore National Laboratory up to $2.5 million to develop an implantable neural device with the ability to record and stimulate neurons within the brain to help restore memory, DARPA officials announced this week.

Science LLNL, MIT researchers develop new ultralight, ultrastiff 3D printed materials
Imagine a material with the same weight and density as aerogel -- a material so light it's called 'frozen smoke' -- but with 10,000 times more stiffness. This material could have a profound impact on the aerospace and automotive industries as well as other applications where lightweight, high-stiffness and high-strength materials are needed.

International Journal of Advanced Manufacturing Technology LLNL researchers develop high-quality 3-D metal parts using additive manufacturing
Lawrence Livermore National Laboratory researchers have developed a new and more efficient approach to a challenging problem in additive manufacturing -- using selective laser melting, namely, the selection of appropriate process parameters that result in parts with desired properties.
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.
