27-Mar-2014 Human-induced climate change reduces chance of flooding in Okavango Delta
Researchers at the University of Cape Town, Lawrence Berkeley National Laboratory 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.
18-Mar-2014 Democratizing science with high-speed networks
For the first time, data collected and analyzed by a very remote user of the Department of Energy's National Center for Electron Microcopy via the Energy Sciences Network has been published. Because of this, scientists are optimistic about the future of remote microscopy for DOE-supported science.
17-Mar-2014 A new mathematics for experimental science
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 Center for Applied Mathematics for Energy Research Applications (CAMERA) at Lawrence Berkeley National Laboratory comes in.
30-Jan-2014 Early Edison users deliver results
Before any supercomputer is accepted at NERSC, scientists are invited to put the system through its paces during an "early science" phase. While the main aim of this period is to test the new system, many scientists are able to use the time to significantly advance their work.
29-Jan-2014 NERSC celebrates 40 years at the forefront
This year, the Department of Energy's National Energy Research Scientific Computing Center (NERSC) is celebrating yet another milestone: its 40th anniversary.
29-Jan-2014 A map made in the heavens
Researchers supported by the Department of Energy's Office of Science have made an incredibly precise map of the universe to better understand dark energy and other wonders within.
27-Jan-2014 Deployments of network monitoring software perfSONAR hit 1,000
Finding the network bottlenecks that can slow the flow of science data sets and impede research can be extremely complex, especially as such data transfers cross a multitude of linked networks. But perfSONAR, a network monitoring software package developed jointly by DOE's Energy Sciences Network, national labs, universities and Internet 2, is making that task much easier. In January 2014, the number of perfSONAR instances installed in the US and 13 other countries reached 1,000.
21-Aug-2012 Berkeley Lab scientists develop new way to study inner workings of algae cells
Berkeley Lab scientists have developed a way to send molecules and proteins across the cell wall of algae, a feat that opens the door for a new way to study and manipulate these tiny organisms. The research could advance the development of algae-based biofuels, pharmaceuticals, and other useful compounds.
26-Oct-2011 Berkeley Lab project in India to measure impact of pollution on cool roofs
With the aid of rooftop instruments, satellite images, an airplane and a balloon, Berkeley Lab scientists are conducting the first-ever study to determine how pollution impacts the efficacy of white roofs in cooling the planet. The yearlong project in northern India will also be the first to take physical measurements to characterize the cooling and climate effects of white roofs.
10-Dec-2010 Berkeley Lab scientist walks the walk -- produces more electricity than he consumes
Energy management engineer Steve Greenberg bikes three miles uphill to work every day, rain or shine. He refuses to use a desktop computer, insisting on a less energy-intensive laptop. And to avoid using paper towels each time he visits the bathroom, he keeps a hand towel in his office. Those are only a few of the things he does to reduce his carbon footprint—and that's just at work.
6-May-2010 A robot called WANDA
Berkeley Lab scientists have established a revolutionary nanocrystal-making robot, capable of producing nanocrystals with staggering precision. This one-of-a-kind robot, named WANDA, provides colloidal nanocrystals with custom-made properties for electronics, biological labeling and luminescent devices. Since this robot is controlled by software protocols, novice users can direct WANDA to perform complex workflows that traditionally require extensive chemistry experience.
23-Jun-2009 Green chemistry: Using lasers to detect explosives and hazardous waste
Berkeley Lab scientists are pioneering laser ablation techniques that can detect explosives and hazardous waste in seconds, with no chemical waste. The technology can save the lives of soldiers, keep children safe from toys illegally coated with lead paints, and protect workers from chemical poisoning.
24-Feb-2009 How 10 trillion bits per square inch assemble themselves perfectly
Two chemically different polymers linked together to form self-assembling block copolymers can have the potential to vastly improve the properties and manufacturing processes of nanostructured materials. Using crystal structures as a template, researchers at Berkeley Lab and the University of Massachusetts Amherst have created perfect arrays of nanoscopic block-copolymer domains, packing 10 trillion bits to the square inch and extending over several square centimeters.
8-Jan-2009 A better way to make nanotubes
A doughnut-shaped molecule synthesized by Berkeley Lab scientists could enable the targeted development of carbon nanotubes, which hold promise for faster electronic devices and other advanced technologies.
2-Dec-2008 Mother of pearl secret revealed
Advanced Light Source scientists Andreas Scholl and Nobumichi Tamura were part of a team that used beams from the PEEM-3 and x-ray diffraction microscopes to reveal new secrets behind the mysterious formation of mother of pearl, or nacre, the inner lining of the shells of abalone and certain other mollusks.
23-Sep-2008 BOSS: the Baryon Oscillation Spectroscopic Survey
One of the most crucial components of the new program of the Sloan Digital Sky Survey and its 2.5 m, wide-field telescope in New Mexico is a unique kind of dark-energy probe called BOSS, the Baryon Oscillation Spectroscopic Survey, led by Berkeley Lab physicists.
7-May-2008 Dark Energy's 10th Anniversary, Part III
The third in a three-part history celebrating the 10th anniversary of the discovery of dark energy, recounting the Supernova Cosmology Project's pioneering efforts to overcome skepticism and prove that indeed it was possible to measure the expansion rate of the universe by using Type Ia supernovae as standard candles. The unexpected results stunned astronomers and physicists alike.
