Measuring Table-Top Accelerators’ State-of-the-Art Beams

Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread

Part Two: Slicing through the electron beam

Wim Leemans of Berkeley Lab’s Accelerator and Fusion Research Division heads LOASIS, the Laser and Optical Accelerator Systems Integrated Studies, an oasis indeed for students pursuing graduate studies in laser plasma acceleration (LPA). Among the most promising applications of future table-top accelerators are new kinds of light sources, in which their electron beams power free electron lasers. (more…)

NASA Maps How Nutrients Affect Plant Productivity

Environment

PASADENA, Calif. – A new analysis led by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. The maps produced from the research will be particularly useful in evaluating how much carbon dioxide Earth’s ecosystems may be able to soak up as greenhouse gas levels increase. (more…)

Study Suggests Antibiotics Might be Another Suspect in Honey Bee Die-off

Nature

The gut bacteria of honey bees have acquired several genes that confer resistance to tetracycline, a direct result of more than five decades of use of antibiotics by American beekeepers and a potential health hazard for bee colonies, a new study by Yale University researchers show.

The genetic analysis of the gut bacteria, which are believed to help in bees’ digestion and ability to ward off parasites, suggests changing antibiotic use by beekeepers might be one factor in the mysterious colony collapse disorder afflicting bee populations. (more…)

A Few Words on Emergency Car Loans

Small Business

To speak of car loans, one might feel that these are one of those complicated forms of loan which take a couple of weeks to be processed and then one might also need to keep his car with the loan providers as the collateral.

Half of Texans Prefer Faith over Science, According to UT/Texas Tribune Poll

Politics

AUSTIN, Texas — About half of Texas voters believe faith is a better guide than scientific evidence on most important questions, according to a recent University of Texas at Austin/Texas Tribune poll.

According to the poll, which surveyed Texans on a wide range of attitudes related to science and public policy, a similar proportion of voters said that “instinct and gut reactions” are just as good as the advice of scientists in most cases.

However, 66 percent of voters said politicians, when faced with a difficult decision, should follow the advice of relevant experts, even if it means going against their ideology. (more…)
