Is indoor air pollution really a problem?

[Physorg.com] How safe is the air we breathe inside our homes and workplaces? contaminants are many and varied, including off-gassing of toxic chemicals called Volatile Organic Compounds (VOCs) from building materials and furniture; carbon monoxide; radon; spores and mycotoxins from mold; pesticides; allergens from pets, insects, dust mites and other sources, and tobacco smoke. The cost of ignoring this issue is steep: a recent study by William Fisk of Lawrence Berkeley National Laboratory concluded that losses due to sick leave, medical treatment, and lowered productivity may be as high as $48 billion annually in the U.S. More>

To Make Clean Energy Cheaper, U.S. Needs Bold Research Push

[Brookings Institution] To renew the U.S. economy, respond to global climate change, foster the nation’s energy security, and help provide the energy necessary to sustainably power global development, America must transform its outdated energy policy. And the national government must play a more active role. To fully mobilize the entire national research enterprise — universities, federal laboratories, and corporate R&D centers — the nation needs to begin creating a network of energy innovation institutes. One such enterprise is the Energy Biosciences Institute, a renewable energy research group involving the UC Berkeley, the University of Illinois at Urbana-Champaign, Berkeley Lab, and the oil giant, BP.

Invisibility cloaks go optical

Two independent groups of physicists claim to have demonstrated invisibility cloaks that operate for light at optical wavelengths. Until now researchers had only been able to create invisibility cloaks for the microwave part of the spectrum. But last week Michal Lipson and colleagues at Cornell University uploaded a preprint on arXiv in which they describe the first demonstration of a cloak that can disguise objects from light in the near infrared to the far red. The following day Berkeley Lab's Xiang Zhang uploaded a preprint in which they describe a cloak for just the near infrared. More>

Berkeley Lab's Role in the Transit Rearrangement

Letter to the Editor:

I would like to clarify information included in the Daily Cal article "Campus Buses, Night Shuttles May Be Given Up to AC Transit" that ran on April 20.

While UC Berkeley is considering turning over the management of its bus service to AC Transit, Berkeley Lab is not part of these negotiations, and is not involved with the campus's decision.

In a separate effort, Berkeley Lab is seeking to provide a more efficient and safer bus service for employees. We are considering the possibility of subcontracting bus services to an outside vendor. This potential move is not a cost-saving measure, and the current level of service will be maintained if not enhanced. As part of the subcontracting process, the Lab will be requiring that vendors provide a plan for hiring all current Lab-career bus drivers. Our intent is to keep our drivers while improving service for our employees and the many students and faculty who come to Berkeley Lab each day.

Solar synergy Dot-com meets green in Sun Microsystems’ Blackbox

The computing industry likes to brag about how much power it puts at our fingertips, but what it doesn’t mention are the megawatts all those computers draw off electrical grids. Jonathan Koomey, a staff scientist at the Lawrence Berkeley National Laboratory, announced in a February 2007 report (funded by Advanced Micro Devices) that the servers and associated infrastructures that run US data centers consumed about $2.7 billion in energy bills in 2005.

Efficient cooking

Which is better: a gas or electric range? Most serious cooks prefer gas, because it delivers heat instantly and is highly controllable. I used to be in the gas cooking camp. But I switched to electric nearly 20 years ago when my two daughters were very young, and I've been surprised at how satisfactory the electric cooking has been. My decision was fueled by studies I read back in the 1980s about possible long-term impacts of breathing gas combustion products in homes, particularly by children. With gas cooktops, it turns out that a lot of the energy content of the gas is not transferred to the food, so cooking efficiency is fairly low: about 40 percent, compared with 74 percent for electric, according to a study by Lawrence Berkeley National Laboratory (LBNL).

Eye on the Bay Highlights Glenn Seaborg


In a segment of the documentary series “Eye on the Bay,” KPIX CBS-5 TV producer David Stoelk interviews physicist Richard Muller and visits the “super-secret” laboratory (well, not at the time—the secrecy came later) on the UC Berkeley campus where, early in 1941, Glenn Seaborg and his colleagues chemically separated plutonium from artificial isotopes they had created with the 60-Inch Cyclotron. View the segment (it starts eight minutes into the video) and take a plutonium trivia quiz on series producer Brian Hackney's blog.

Two Cal professors to get $30M from DOE for carbon capture work


The Department of Energy will pay $30 million over five years to two professors at the University of California, Berkeley, for research on cleaning up power plant pollution.Professors Berend Smit and Donald DePaolo will get $2 million and $4 million a year, respectively, to seek better ways to clean carbon out of the emissions from power plants and natural gas wells and to put it underground.

This “carbon capture and sequestration” technology will keep carbon dioxide out of the atmosphere, where it is believed to add to global warming.Smit is a chemist and DePaolo is a geologist and head of the Earth Sciences unit at Lawrence Berkeley National Laboratory on the hill above U.C. Berkeley’s campus. More>

From green leaves to bird brains, biological systems may exploit quantum phenomena

Until a century or so ago, nobody had any idea that there even was such a thing as quantum physics. But while humans operated for millennia in quantum darkness, it seems that plants, bacteria and birds may have been in the know all along. Now, with growing evidence that quantum weirdness indeed exists in biological systems, scientists are looking for ways to tell how, or even if, nature exploits these effects to confer an advantage. "We can't tell nature to ignore quantum mechanics, so we might need to measure it and see what happens," says Berkeley Lab's Graham Fleming. More>

Riding the Giant ‘Solarcoaster’

[Site Selection] How rosy is the outlook for solar energy? On the one hand, the stimulus bills represent the largest national commitment to clean energy in U.S. history. On the other hand, the renewable energy industry is not immune to the trends dragging down the global economy. A recent report from the Lawrence Berkeley National Laboratory found that tax equity yields increased by up to 200 basis points, which would translate into a 7-cent per kilowatt-hour spike in the price of solar electricity.

Better Way to Wire Up Cells

[Technology Review] Understanding how brain and heart cells process and generate electrical signals could lead to a new understanding of neurological and heart disease. Until a few years ago, however, it simply wasn't possible to make electrical recordings at the level of single cells. In 2006, Harvard researchers used nanowire transistors to measure electrical signals at 50 points along a single neuron. Now the same research group has developed a new nanowire recording system and have used it to capture some of the most precise, high-quality electrical recordings ever made from heart cells." The modular approach is quite elegant," says Peidong Yang, with Berkeley Lab. Yang has used nanowire arrays to study the effects of electrical inputs on stem-cell development. More>

Can Small Cars Overcome Crash Fears?

The U.S. government's push to decrease the nation's output of greenhouse gases by increasing the fuel efficiency of the cars Americans drive is rekindling an emotional debate: Does driving a small, fuel-efficient car make you more likely to die on the road? Tom Wenzel, a researcher at the Lawrence Berkeley national laboratory who analyzes vehicle crash data, says better fuel economy and safety can be compatible, provided car makers make smart use of technology and policy makers take steps to reduce the disparity in the size of vehicles on the road.

A Hybrid Nano-Energy Harvester

Researchers have combined a nanogenerator with a solar cell to create an integrated mechanical- and solar-energy-harvesting device. This hybrid generator is the first of its kind and might be used, for instance, to power airplane sensors by capturing sunlight as well as engine vibrations. It combines two previously developed technologies, both of which rely on zinc oxide nanowires, in a layered silicon substrate. The top layer consists of a thin-film solar cell embedded with dye-coated zinc oxide nanowires. The large surface area of the nanowires boosts the device's light absorption, a design based on work by Berkeley Lab's Piedong Yang. More>

Has global warming really stopped?

[New Scientist] According to some records of past temperatures there has been no significant surface warming between 1998 and 2008. "Now the world is COOLING!" the bloggers scream. As if this means we can all stop worrying about global warming. There was also no significant warming trend from between 1977 and 1985, or between 1981 and 1989 - and those periods certainly weren't the end of global warming. Now, as if more evidence were needed, two climate scientists — including Berkeley Lab's Michael Wehner — have produced more data showing that the current lull in no way contradicts the fact that human emissions of greenhouse gases are causing long-term warming.

Op-Ed: Will Misleads Readers on Climate Science - Again

During the past three months, George Will has written three columns on global climate change, each of which has been controversial. Will's climate change columns are a case study in how one can cherry pick scientific data to fit their own agenda. He fails to accurately convey a fundamental facet of the global warming story, which is that human influences on the climate system take place within the context of the planet's natural climate variability. As a forthcoming scientific study — coauthored by Berkeley Lab's Michael Wehner — makes clear, man made global warming is not likely to take place in a monotonic manner, instead, as can be seen throughout the observational climate record, there will be zigs and zags in the temperature graph.
