White, green or black roofs? Berkeley Lab report compares economic payoffs
Looking strictly at the economic costs and benefits of three different roof types -- black, white and "green" (or vegetated) -- Lawrence Berkeley National Laboratory researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden.

Natural 3-D counterpart to graphene discovered
A natural 3-D counterpart to 2-D graphene with similar or even better electron mobility and velocity has been discovered at Berkeley Lab's Advanced Light Source. This discovery promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives.

Berkeley Lab-led project aims to produce liquid transportation fuel from methane
How's this for innovative: A Berkeley Lab-led team hopes to engineer a new enzyme that efficiently converts methane to liquid transportation fuel. "There's a lot of methane available, and we want to develop a new way to harness it as an energy source for vehicles," says Christer Jansson, a biochemist in Berkeley Lab's Earth Sciences Division who heads the effort.

BOSS measures the universe to 1-percent accuracy
The Baryon Oscillation Spectroscopic Survey (BOSS), led by scientists at Lawrence Berkeley National Laboratory, is the largest component of the third Sloan Digital Sky Survey. BOSS has measured the clustering of nearly 1.3 million galaxies spectroscopically, determining the "standard ruler" of the universe's large-scale structure to within one percent. This is the most precise such measurement ever made and likely to be the standard for years to come.

Studies find methane emissions in California and US 1.5 times greater than expected
Current official inventories of methane emissions, a potent greenhouse gas released from landfills, livestock ranches and oil and gas facilities, may be underestimated both nationally and in California by a factor of about 1.5, according to new research from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and others.

Holistic cell design leads to high-performance, long cycle-life Li/S battery
Researchers at Berkeley Lab have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery's capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.

A superconductor-surrogate earns its stripes
Understanding superconductivity -- whereby certain materials can conduct electricity without any loss of energy -- has proved to be one of the most persistent problems in modern physics. Now scientists at Berkeley Lab have teased out another important tangle from this giant ball of string, bringing us a significant step closer to understanding how high-temperature superconductors work their magic.

'Molecular Velcro' may lead to cost-effective alternatives to natural antibodies
Taking inspiration from the human immune system, researchers at Berkeley Lab have created a new material that can be programmed to identify an endless variety of molecules. The new material resembles tiny sheets of Velcro, each just 100 nanometers across. But instead of securing your sneakers, this molecular Velcro mimics the way natural antibodies recognize viruses and toxins, and could lead to a new class of biosensors.
