Lab Cybersecurity Experts Monitor ‘Heartbeat’ of Heartbleed Bug

Friday, April 18th, 2014

[New York Times] Ever since the Heartbleed bug was exposed last week, the question everyone has been asking is: Did anyone exploit it before a Google researcher first discovered it? Security researchers at Berkeley Lab’s Computational Research Division and NERSC say that it is still possible to look for past Heartbleed exploitations by measuring the size of any messages sent to the vulnerable part of the OpenSSL code, called the Heartbeat, and the size of the information request that hits a server.

CRD’s John Shalf Discusses Big Data with White House Staff

Wednesday, April 2nd, 2014

John Shalf, head of CRD’s Computer and Data Sciences Department, was one of four national laboratory representatives to meet with President Obama’s chief of staff, and members of the Office of Science and Technology Policy (OSTP), Office of Management and Budget (OMB) and other federal agencies to discuss the intersection of big data architecture requirements and exascale challenges. The March 25 meeting was held in the Eisenhower Executive Office Building next to the White House, which houses most of the White House staff. More>

Human-Induced Climate Change Reduces Chance of Flooding in Okavango Delta

Monday, March 31st, 2014

Researchers at the University of Cape Town, Berkeley Lab, and the United Nations Development Programme have analyzed how human-induced climate change has affected recent flooding in an ecologically and geographically unique river basin in southern Africa — the Okavango River. After running a number of simulations, they found that greenhouse gas emissions have substantially reduced the chance of the floods in the region. More>

A New Mathematics for Experimental Science

Wednesday, March 19th, 2014

In the age of high-resolution detectors and international research collaborations, math has the potential to transform science and accelerate discovery. But this work will require state-of-the-art mathematics, carefully crafted in inventive new ways. That’s where the Department of Energy’s new Center for Applied Mathematics for Energy Research Applications (CAMERA) at Berkeley Lab comes in. More>

Happy Pi Day: A Conversation With Lab’s ‘Pi Guy’ David Bailey

Friday, March 14th, 2014

In 1993 B.G. (before Google), when writers for The Simpsons needed the 40,000th decimal digit of π (pi) for a punch line in season four’s “Marge in Chains”episode, they turned to mathematician and computer scientist David Bailey who confirmed that the digit was 1. And his reputation as the “Pi Guy” was set. But Bailey’s professional relationship with pi began years before Hollywood writers came calling. More>

The Great Lights of Europe: A Study in Synchrotron Data Management and Analysis

Wednesday, February 26th, 2014

David Brown and Craig Tull of the Computational Research Division and Alex Hexemer of the Advanced Light Source recently spent 10 days in Europe seeing the lights — light sources that use intense X-rays to study materials. Facilities like the ALS are becoming increasingly powerful discovery tools with the development of higher-resolution detectors. Thus, beamline scientists are facing unprecedented amounts of data, but not always with the infrastructure needed to manage and analyze that data. To see how this situation is being addressed elsewhere, Brown, Tull and Hexemer toured some of Europe’s leading light sources and other facilities. More>

March 8 Memorial Service for Computing’s Gail Jackson-Maeda

Thursday, February 20th, 2014

A memorial service will be held Saturday, March 8, for Gail Jackson-Maeda, a Berkeley Lab administrative assistant who died Feb. 5 after a long battle with cancer. The service will be held at 1:30 p.m. at the Unity Center, 1871 Geary Road, in Walnut Creek. Jackson-Maeda joined Berkeley Lab in 2008 and was the administrative assistant for the Advanced Computing for Science Department (ACS) in the Computational Research Division. Memorial donations may be made to any breast cancer research program. She is survived by her husband and son.

Bubble Visualization Honored by 2013 Visualization Challenge

Monday, February 10th, 2014

A visualization of soap bubbles bursting and reforming, created by Berkeley Lab mathematicians Robert Saye and James Sethian, has won honorable mention in the 2013 International Science and Engineering Visualization Challenge, sponsored by Science magazine and the National Science Foundation.

CRD’s Taghrid Samak Profiled as HPC Innovator

Friday, February 7th, 2014

[Scientific Computing] Taghrid Samak of Berkeley Lab’s Computational Research Division admits with a laugh that she wasn’t one of those kids who started programming on the home computer at age 10. And if she hadn’t followed her father’s advice, she might have ended up looking for political solutions to pressing problems, rather than working on computational approaches to scientific challenges.

High-Throughput Scintillator Discovery Project Receives DNDO IAA Award

Wednesday, January 29th, 2014

A high-throughput scintillator discovery project lead by Stephen Derenzo (pictured) of Life Sciences and Edith Bourret-Courchesne of Material Sciences, in collaboration with Andrew Canning of Computational Research, has received an Inter-Agency Agreement (IAA) award of over $1.3M from the Domestic Nuclear Detection Office (DNDO) for 2014. The project uses empirical rules to select the most promising candidates from the vast number of possible compounds and then uses unique custom-built high-throughput systems for synthesis and characterization. The project has been very successful at identifying new high-luminosity scintillators: Of the 33 new scintillators that were published after 2005 with luminosities above 30,000 photons/MeV, 20 (61%) were discovered by this project.
