Troubling levels of toxic metals found in lipstick


A new analysis of the contents of lipstick and lip gloss may cause you to pause before puckering. Researchers at the University of California, Berkeley's School of Public Health tested 32 different lipsticks and lip glosses commonly found in drugstores and department stores. They detected lead, ...


A rock is a clock: Physicist uses matter to tell time

Turning a cesium atom into Compton clock based on the frequency of its matter wave


Ever since he was a kid growing up in Germany, Holger Müller has been asking himself a fundamental question: What is time? That question has now led Müller, today an associate professor of physics at the University of California, Berkeley, to a fundamentally new way of measuring time.Taking ...

New materials could slash energy costs for CO2 capture

Study IDs 'zeolite' minerals that are one-third more efficient for carbon capture


A detailed analysis of more than 4 million absorbent minerals has determined that new materials could help electricity producers slash as much as 30 percent of the "parasitic energy" costs associated with removing carbon dioxide from power plant emissions.The research by scientists at Rice ...

New material cuts energy costs of separating gas for plastics and fuels

Metal-organic framework captures saturated hydrocarbons, letting pure unsaturated gases through


A new type of hybrid material developed at the University of California, Berkeley, could help oil and chemical companies save energy and money – and lower their environmental impacts – by eliminating an energy-intensive gas-separation process. Today, to separate hydrocarbon gas mixtures into the ...

Breakthrough in designing cheaper, more efficient catalysts for fuel cells

Chemists take new approach: synthesizing catalysts that are all edge


University of California, Berkeley, chemists are reimagining catalysts in ways that could have a profound impact on the chemical industry as well as on the growing market for hydrogen fuel cell vehicles. Catalysts are materials typically metals that speed up chemical reactions and are widely used ...


Scientists probe the energy transfer process in photosynthetic proteins


Researchers have developed a new method to probe the fundamental workings of photosynthesis. The new experimental technique could help scientists better understand the nitty-gritty details of nature's amazingly efficient sunlight-to-fuel conversion system. Plants and other photosynthetic ...


Flame retardant linked to altered thyroid hormone levels during pregnancy


Pregnant women with higher blood levels of a common flame retardant had altered thyroid hormone levels, a result that could have implications for fetal health, according to a new study led by researchers at the University of California, Berkeley. "This is the first study with a sufficient ...


Ironing out materials for gas storage and separations


An iron-based porous solid that can store hydrogen and capture carbon dioxide, potentially leading to greener energy and cleaner air, has been made by US scientists. Jeffrey Long, at the University of California, Berkeley, and colleagues made a metal-organic framework (MOF) with accessible Fe2+ ...


Berkeley scientists discover inexpensive metal catalyst for generating hydrogen from water


Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with the U.S. Department of ...

Designer nanomaterials on-demand


Composites are combinations of materials that produce properties inaccessible in any one material. A classic example of a composite is fiberglass - plastic fibers woven with glass to add strength to hockey sticks or the hull of a boat. Unlike the well-established techniques for producing ...
