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.

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.

Lawrence Livermore research finds early Mesoamericans affected by climate change
Scientists have reconstructed the past climate for the region around Cantona, a large fortified city in highland Mexico, and found the population drastically declined in the past, at least in part because of climate change.

New research re-creates planet formation, super-earths and giant planets in the laboratory
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planets' formation and evolution processes.

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.

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.

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.

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.
