West Antarctic Ice Sheet may be on “the brink of change”
A project to map the Weddell Sea area of the West Antarctic Ice Sheet from the air has revealed that this largely unexplored region is potentially on the threshold of change.
"If the ocean water under an ice shelf warms, even by a few degrees Celsius, the ice shelf will melt much faster. If it melts faster, it will thin and cause an acceleration in the flow of grounded glacial ice into the ocean. This acceleration of glacial flow, when applied to the massive glaciers that drain the Antarctic ice sheet, can easily result in multiple meters of global sea level rise over timescales of hundreds to thousands of years," said Jeremy Fyke, glacier and sheet modeler at Los Alamos National Laboratory.

Researchers test theory of planets

Recent research by Jarrett Johnson and Hui Li of LANL’s Nuclear and Particle Physics, Astrophysics and Cosmology group suggests that the first planets in the universe formed well after the first generations of stars.
The scientists calculated the minimum metallicity that must be present in the dusty disks surrounding newborn stars in order for planets to take shape. (Full Story)
DOE hybrid cloud may be model for future
The Department of Energy and the National Nuclear Security Administration are creating a cloud computing environment that could be a model for other federal agencies.
An integrated project team with representatives from DOE and NNSA is developing the hybrid, community cloud, which builds on an infrastructure-as-a-service environment deployed at Los Alamos National Laboratory. (Full Story)

Shine Medical Technologies and its partner, the Morgridge Institute for Research, will collaborate on a $20.6 million cooperative agreement to develop a new process for the production of molybdenum-99.
The project team, which includes collaborators at Phoenix Nuclear Labs, the University of Wisconsin–Madison, Argonne National Laboratory, Savannah River National Laboratory and Los Alamos National Laboratory, is led by the Morgridge Institute. (Full Story)
Video: Cyber Security Defense Using HPC
"Adversaries in the cyber domain continue to escalate their use of more sophisticated attacks and associated detection countermeasures. As a result, the difficulty and complexity of finding such adversaries and their attacks increasingly challenges cyber defenders. Traditionally, high performance and parallel computing (HPC) has been a successful tool in tackling complex problems, particularly over large data sets. Yet it has only been recently that HPC has successfully impacted the cyber defense problem," said Alex Kent from Los Alamos National Laboratory. (Full Story)
