Building Performance Database Helps Building Owners, Investors Evaluate Energy Efficient Buildings
A new database of building features and energy use data helps building managers, owners, real estate investors, and lenders evaluate the financial results of energy efficiency investment projects and identify high and low-performing buildings. The database is being developed by a Berkeley Lab team led by Paul Mathew.
California’s efforts to clean up diesel engines have helped reduce impact of climate change on state, study finds
Reductions in emissions of black carbon since the late 1980s, mostly from diesel engines as a result of air quality programs, have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a first-of-its-kind study--which Berkeley Lab participated in-- examining the impact of black carbon on California’s climate.
Berkeley Lab Study Finds Moving Select Computer Services to the Cloud Promises Significant Energy Savings
A six-month study led by Berkeley Laboratory, with funding from Google, has found that moving common software applications used by 86 million U.S. workers to the cloud could save enough electricity annually to power Los Angeles for a year.
Berkeley Lab Researchers Increase NMR/MRI Sensitivity through Hyperpolarization of Nuclei in Diamond
Berkeley Lab researchers have demonstrated the first magnetically-controlled nearly complete hyperpolarization of the spins of carbon-13 nuclei located near synthetic defects in diamond crystals. This spin hyperpolarization, which can be carried out with refrigerator-style magnets at room temperature, enhances NMR/MRI sensitivity by many orders of magnitude.
Roman Seawater Concrete Holds the Secret to Cutting Carbon Emissions
At the Advanced Light Source, scientists analyzed samples from a Roman breakwater that has been submerged in the Bay of Naples for over two millennia, revealing the secrets of crystal chemistry that allow Roman seawater concrete to resist chemical attack and wave action for centuries. The manufacture of extraordinarily durable Roman maritime concrete released much less carbon than most modern concrete does today and presents important opportunities for improving quality and reducing atmospheric carbon.
Berkeley Lab Researchers Discover How and Where Breast Tumor Cells Become Dormant and What Causes Them to Become Metastatic
Berkeley Lab researchers have identified the microenvironment surrounding microvasculature as a niche where dormant breast cancer cells may reside, and the sprouting of microvasculature blood vessels as the event that transforms dormant cancer cells into metastatic tumors.
Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act
Berkeley Lab scientists have produced remarkable images of carbon atoms and the bonds among them. Resembling glowing textbook diagrams, hydrocarbon molecules are shown in high resolution for the first time before and after the breaking, rearrangement of atoms, and reforming of bonds during a complex chemical reaction.
Models from Big Molecules Captured in a Flash
The structures of most of the two million proteins in the human body are still unknown, even at low resolution. A new algorithm developed by Berkeley Lab scientists solves the convoluted shapes of large molecules by using images of numerous individual samples, all caught simultaneously in a split-second flash of x-rays from a free-electron laser. The technique promises efficient information about the shapes of many more large biological molecules in their native, fluid state.
