Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable ...
Interactive maps of US metro areas shows striking differences between cities and suburbs
According to a new study by researchers at the University of California, Berkeley, population-dense cities contribute less greenhouse gas emissions per person than other areas of the country, but these cities' extensive suburbs essentially wipe out the climate benefits. Dominated by emissions ...
Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases
Years of experiments on various types of high-temperature (high-Tc) superconductors—materials that offer hope for energy-saving applications such as zero-loss electrical power lines—have turned up an amazing array of complex behaviors among the electrons that in some instances pair up to ...
Nearly every body of water, from a puddle or a pond to a vast ocean, contains microscopic organisms that live attached to rocks, plants, and animals. These so-called sessile suspension feeders are critical to aquatic ecosystems and play an important role in cleaning up environmental ...
Gems for new technology
A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers – defects in which two adjacent carbon atoms in the diamond's crystal structure are ...
Berkeley Lab and UC Berkeley researchers develop method for predicting adsorption in carbon dioxide-scrubbing materials
Scientists would like to apply the same principles by which baking soda removes food odors from refrigerators or silica powder keeps moisture away from electronic devices to scrub carbon dioxide from the exhaust gases of fossil fuel power plants. An excellent candidate for this task is the ...
Physicists use dysprosium to put bounds on maximum speed of electrons
Albert Einstein's assertion that there's an ultimate speed limit – the speed of light – has withstood countless tests over the past 100 years, but that didn't stop University of California, Berkeley, postdoc Michael Hohensee and graduate student Nathan Leefer from checking whether some ...
Every chemist’s dream – to snap an atomic-scale picture of a chemical before and after it reacts – has now come true, thanks to a new technique developed by chemists and physicists at the University of California, Berkeley. Using a state-of-the-art atomic force microscope, the scientists have ...
Berkeley Lab scientists make the first-ever high-resolution images of a molecule as it breaks and reforms chemical bonds
When Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, the first result was a surprise: spectacular images of individual carbon atoms ...
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 ...
