An earthquake measuring 6.3 rocked Christchurch three miles from the city center, and news reports have estimated 75 deaths with more than 300 people still missing.
“The locality beneath Christchurch is definitely surprising, but everything else is not so surprising,” said Hua-wei Zhou, the Pevehouse Chair and Professor of Petroleum Geophysics and Seismology in the Department of Geosciences. “This is the sixth aftershock measuring 5.0 or more since the last big earthquake on Sept. 3, 2010.”
Zhou explained that while the Sept. 3, 2010, earthquake measured 7.0 in magnitude, it happened in a relatively rural area 30 miles west of Christchurch and didn’t cause as much damage. Because of the earthquake’s location and the fault’s motion – a strike-slip motion with plates grinding horizontally with some vertical movement also – this may have intensified the damage in an already heavily populated area.
Because of the historical rarity of earthquakes in the city, Zhou predicted that the Christchurch area most likely wouldn’t experience another earthquake for several years to decades.
In May 2008, Zhou led a team of six graduate students to deploy 60 seismometers near the Three Gorges Dam after an earthquake measuring 7.9 struck the Sichuan province in Central China. Zhou's research interests include improving seismic imaging methods and mapping mantle and crustal seismic structures of various regions.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

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...
