SLAC research resumes at upgraded Large Hadron Collider
Research with the Large Hadron Collider has officially resumed: The world's largest particle accelerator at CERN began on June 3 to collect data at a new record energy that could hold the key to new scientific discoveries. To keep up with the boost in performance, researchers at the Department of Energy's SLAC National Accelerator Laboratory have developed new technologies for ATLAS -- one of two experiments involved in the 2012 discovery of the Higgs boson.

Meraculous: Deciphering the 'book of life' with supercomputers
A team of scientists from Berkeley Lab, JGI and UC Berkeley, simplified and sped up genome assembly, reducing a months-long process to mere minutes. This was primarily achieved by 'parallelizing' the code to harness the processing power of supercomputers, such as NERSC's Edison system.

The 'why' of models
An international team of researchers from Oak Ridge National Laboratory, Macquarie University, the University of Western Sydney and the Max Planck Institute for Biogeochemistry set out to assess how two Free-Air CO2 Enrichment projects compared to eleven vegetation models that simulate various ecological processes. Instead of only benchmarking whether or not an individual model matched the experimental data, the researchers developed an 'assumption-centered' approach to evaluate why certain models performed better than others.

New method relates Greenland ice sheet changes to sea-level rise
Climate models are not yet able to include full models of the Greenland and Antarctic ice sheets and to dynamically simulate how ice sheet changes influence sea level. Early schemes failed to accurately account for mass increase due to snowfall and mass loss due to snow melt. These changes depend on ice sheet elevation and region. A new method that includes the effects of elevation and region was developed.

New mathematical method enhances hydrology simulations
Just as a racecar's engine needs the right fuel to get the best performance, so climate models need finely tuned parameters to accurately simulate the impacts of different technologies and policies. Led by researchers at Pacific Northwest National Laboratory, a team applied sophisticated mathematical solutions to fine tune the water and energy exchange parameters, numerical stand-ins for complex processes, to better simulate water and energy fluxes.

BigNeuron: Unlocking the secrets of the human brain
To find a standard 3-D neuron reconstruction algorithm, Big Neuron will sponsor a series of international hackathons and workshops where contending algorithms will be ported onto a common software platform to analyze neuronal physical structure using the same core dataset. All ported algorithms will be bench-tested at DOE's NERSC and ORNL, as well as Human Brain Project supercomputing centers.

Pinpointing the magnetic moments of nuclear matter
Using supercomputing resources at the National Energy Research Scientific Computing Center at Berkeley Lab, a team of nuclear physicists has demonstrated for the first time the ability of quantum chromodynamics (QCD) -- a fundamental theory in particle physics -- to calculate the magnetic structure of some of the lightest nuclei. Their findings are part of an ongoing effort to further our understanding of the universe.

A standard for neuroscience data
In November, Neurodata without Borders hosted a hackathon to consolidate ideas for designing and implementing a standard neuroscience file format. And BrainFormat, a neuroscience data standardization framework developed at Berkeley Lab, was one of several candidates selected for further investigation. It is now a strong contender to contribute to the development of a community-wide data format and storage standard for the neuroscience research community.

Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.

Berkeley Lab algorithms help researchers understand dark energy
To unlock the mystery of dark energy and its influence on the universe, researchers must rely on indirect observations -- watching how fast Type Ia supernovae recede from us as the universe expands. The process of identifying and tracking these objects requires scientists to scrupulously monitor the night sky for slight changes, a task that would be tedious and time-consuming for the Dark Energy Survey without novel tools developed by Berkeley Lab and UC Berkeley researchers.
