Over the next few weeks researchers at the National Nuclear Security Administration’s Sandia National Laboratories will begin testing innovative ways to treat arsenic-contaminated water in an effort to reduce costs to municipalities of meeting the new arsenic standard issued by the U.S. Environmental Protection Agency (EPA). The testing is sponsored by the Arsenic Water Technology Partnership (AWTP), a multiyear-program funded by a congressional appropriation through the U.S. Department of Energy.
"The goals of the program are to develop, demonstrate, and disseminate information about cost-effective water treatment technologies in order to help small communities in the Southwest and other parts of the country comply with the new EPA standard," says Malcolm Siegel, Sandia Arsenic Treatment Technology Demonstration Project Manager.
The tests will be conducted at a geothermal spring used to supply drinking water to Socorro, N.M., a town of about 9,000 residents located 80 miles south of Albuquerque. Installation of test equipment will be completed in December by Sandians Randy Everett and Brian Dwyer, and regular operations will begin before Christmas following a preliminary "shakedown" period. Another member of the team, Alicia Aragon, will present results of laboratory studies supporting the pilot tests at the Fall Meeting of the American Geophysical Society in San Francisco next week.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
