Highly anxious people have more trouble deciding how best to handle life’s uncertainties. Investigating this dynamic, scientists have found evidence of a glitch in the brain’s higher-order decision-making circuitry that could eventually be targeted in the treatment of anxiety disorders.
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from Berkeley Laboratory and UC Berkeley.
Rather than extending access to new families, Mayor Bill de Blasio’s robust expansion of free preschool across New York City has instead drawn thousands of children from existing programs and aided better-off families who already enjoyed abundant preschool supply.
The brain’s speech area, named after 19th century French physician Pierre Paul Broca, shuts down when we talk out loud, according to a new study that challenges the long-held belief that “Broca’s area” governs all aspects of speech production.
Laura Waller is working on computational imaging methods for quantitative phase microscopy, which enables one to map the shape and/or density of invisible samples in a non-invasive way. Her group is developing simple experimental architectures and efficient post-processing algorithms for phase recovery, applied in a variety of scientific and industrial settings.
Biomass conversion to electricity combined with new technologies for capturing and storing carbon, which should become viable within 35 years, could result in a carbon-negative power grid in the Western United States by 2050.
UC Berkeley scientists have found the mechanism by which titanium, prized for its high strength-to-weight ratio and natural resistance to corrosion, becomes brittle with just a few extra atoms of oxygen.
