In its third quarterly report of 2011, the UCLA Anderson Forecast says the outlook for the nation’s economy is “far worse” than it was just three months ago.
Considering the weak, revised data for the first half of the year, the forecast calls for average gross domestic product growth of just 0.9 percent on average for the five quarters — this year’s four and the first quarter of 2012.
However, Forecast economists remain steadfast in their assertion that the U.S. is not currently in a recession, nor is there a recession in the forecast through 2013. (more…)
*Berkeley Lab Researchers Show How Loss of Bone Quality Also a Major Factor*
It is a well-established fact that as we grow older our bones become more brittle and prone to fracturing. It is also well established that loss of mass is a major reason for older bones fracturing more readily than younger bones, hence medical treatments have focused on slowing down this loss. However, new research from scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss of quantity in the susceptibility of bone to fracturing.

PASADENA, Calif. — NASA’s Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.
Dawn will study the asteroid, named Vesta, for a year before departing for a second destination, a dwarf planet named Ceres, in July 2012. Observations will provide unprecedented data to help scientists understand the earliest chapter of our solar system. The data also will help pave the way for future human space missions. (more…)
*High-mountain wildflower season reduced, affecting pollinators like bees, hummingbirds*
It’s summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.
But for how long?
Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season. (more…)
Fluctuations in climate can drastically affect the habitability of marine ecosystems, according to a new study by UCLA scientists that examined the expansion and contraction of low-oxygen zones in the ocean.
The UCLA research team, led by assistant professor of atmospheric and oceanic sciences Curtis Deutsch, used a specialized computer simulation to demonstrate for the first time that the size of low-oxygen zones created by respiring bacteria is extremely sensitive to changes in depth caused by oscillations in climate. These oxygen-depleted regions, which expand or contract depending on their depth, pose a distinct threat to marine life. (more…)
*Berkeley Lab joint report offers a variety of scenarios to reduce emissions to 80% below 1990 levels.*
Berkeley, CA — In the next 40 years, California’s population is expected to surge from 37 million to 55 million and the demand for energy is expected to double. Given those daunting numbers, can California really reduce its greenhouse gas emissions to 80 percent below 1990 levels by 2050, as required by an executive order? Scientists from Lawrence Berkeley National Laboratory who co-wrote a new report on California’s energy future are optimistic that the target can be achieved, though not without bold policy and behavioral changes as well as some scientific innovation.
The report, titled “California’s Energy Future—The View to 2050,” draws a series of energy system “portraits” showing how California can meet its ambitious emissions targets using a combination of measures and energy sources that may include electrification, enhanced efficiency, nuclear energy, renewable energy sources, grid modernization, and carbon capture and sequestration (CCS).

Such highly coveted technical capabilities as the observation of single catalytic processes in nanoreactors, or the optical detection of low concentrations of biochemical agents and gases are an important step closer to fruition. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart in Germany, report the first experimental demonstration of antenna-enhanced gas sensing at the single particle level. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, they were able to clearly detect changes in the palladium’s optical properties upon exposure to hydrogen. (more…)
When a team of researchers from the National Oceanic and Atmospheric Administration and the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences raced to the scene of the BP Deepwater Horizon oil spill to assess the disaster’s impact on air quality last year, they found more than they expected.
