Overcoming resistance
To find a path around antibiotic resistance, a team working with the Intrepid supercomputer at Argonne National Laboratory is simulating molecular binding interactions to rapidly vet new infection-fighting candidates.

Kinky nanotubes
With the help of Oak Ridge computations, scientists are probing the properties of macroscale sponges made of nanoscale carbon-boron tubes. The material could soak up oil spills, help store energy or meet other needs.
A passion for pressure
Plasmas are the purview of Livermore scientist and Computational Science Graduate Fellowship alumnus Jeffrey Hittinger. He works both sides of the fusion street – inertial confinement and magnetic confinement – while simulating aspects of these tremendously hot, fast-moving particle clouds.

Twice-stuffed permafrost
A Pacific Northwest National Laboratory computation suggests that the water-gas compounds found in ocean permafrost can provide energy and store it, too – and then trap carbon dioxide.

Inside the skull
Modeling the elements of blood flow in the brain could help neurosurgeons to predict when and where an aneurysm might rupture – and when to operate.
Power boost
Berkeley scientists have combined computational modeling and advanced materials synthesis to devise a low-cost anode that bolsters the feasibility of long-life lithium-ion batteries.
Helping hydrogen along
Researchers have pursued clean hydrogen-based fuels for years. A Berkeley Lab team hopes to spur that quest with help from one of the world’s most powerful computers.

A long view of Gulf oil spill
While others predicted when oil from the Deepwater Horizon spill in the Gulf of Mexico might reach beaches, ocean modelers at Los Alamos National Laboratory and the National Center for Atmospheric Research asked when gushing oil might exit the Gulf, where it would go and how diluted it’d be, up to a year later.

Pounding out atomic nuclei
Thousands of tiny systems called atomic nuclei – specific combinations of protons and neutrons – prove extremely difficult to study but have big implications for nuclear stockpile stewardship. To describe all of the nuclei and the reactions between them, a nationwide collaboration is devising powerful algorithms that run on high-performance computers.

Extending the stockpile’s lifespan
Just how does prolonged exposure to nuclear radiation change a material’s properties? How do those changes alter the way a weapon performs? A Los Alamos team quantifies these and other uncertainties.
