The San Andreas Fault Observatory at Depth (SAFOD)-the first underground observatory to provide physical samples and real-time seismological data from deep inside an active fault zone-is yielding surprising new clues about the origin of earthquakes. SAFOD scientists from around the world will discuss these new findings on Dec. 6 at the annual meeting of the American Geophysical Union (AGU) at Moscone Center West in San Francisco.
SAFOD is a major research component of EarthScope, a National Science Foundation-funded program being carried out in collaboration with the U.S. Geological Survey (USGS) to investigate the forces that shape the North American continent and the physical processes controlling earthquakes and volcanic eruptions.
The SAFOD project is located near the tiny Central California town of Parkfield on the notorious San Andreas Fault-an 800-mile-long earthquake-prone rift that runs between the Pacific and North American tectonic plates. Drilling of the three-mile-long SAFOD borehole began in June 2004 on the Pacific plate just west of the fault. In August 2005, project leaders achieved their goal of drilling through the active fault zone into the North American plate, reaching a depth of 10,081 feet (1.91 miles). When completed in 2007, the observatory will be equipped with dozens of underground seismological instruments installed in a segment of the fault where small earthquakes are born.

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...
