Exascale refers to high-performance computing systems capable of at least a billion billion calculations per second, or 50 to 100 times faster than the nation’s most powerful supercomputers. The projects target advanced modeling and simulation solutions to specific challenges supporting key DOE missions.
Catherine “Reba” Siero has worked as an accelerator operator for more than two decades at the Lab’s 88-Inch Cyclotron. Her comfort zone is here in the control room, surrounded by walls bristling with a busy mix of modern and time-tested knobs, dials, buttons, glowing lights, switches and screens. Siero retires next month after 37 years at the Lab.
A new study links the overexpression of 14 genes related to cell division to cancer patients’ prognosis and response to specific treatments. The findings could be used to develop a biomarker used to make more informed decisions about cancer therapy.
Researchers have created a sort of nanoscale display case that enables new atomic-scale views of hard-to-study chemical and biological samples. Their work could help to reveal new structural details for a range of challenging molecules, such as complex chemical compounds and potentially new drugs, by stabilizing them inside metal-organic frameworks (MOFs).
Follow Berkeley scientists on a 10-day research voyage off the California coast as they test robotic floats in studies of the ocean’s biological carbon pump, which could aid the understanding of climate change. Sarah Yang from Public Affairs is tagging along and will blog daily about the trip, including photos and a map tracking their location.
DESI (Dark Energy Spectroscopic Instrument) — a 3-D sky-mapping project that will measure the light of millions of galaxies and explore the nature of dark energy — has received approval to move forward with construction, which is scheduled to begin next year. Observations will start in January 2019.
The Introductory College Level Experience in Microbiology (iCLEM) program provides Bay Area high school students with valuable hands-on experience in the lab and guidance for continuing a career in science. The students are hosted by the Joint BioEnergy Institute.
There’s a new tool in the push to engineer rechargeable batteries that last longer and charge more quickly. An X-ray microscopy technique recently developed at Advanced Light Source has given scientists the ability to image nanoscale changes inside lithium-ion battery particles as they charge and discharge.
A new Lab study measures the toxic compounds in e-cigarette emissions and shows how factors such as the temperature, type, and age of the device play a role in emission levels, information that could be valuable to both manufacturers and regulators seeking to minimize the health impacts of these increasingly popular devices.
JBEI scientists have shown that adding carbon dioxide gas during the deconstruction phase of biofuel production successfully neutralized the toxicity of ionic liquids. The technique, which is reversible, allows the liquid to be recycled, representing a major step forward in streamlining the biofuel production process.
