NASA's GOES Project released a satellite animation of the Puyehue-Cordón Caulle volcano that shows the movement of the ash plume over several days. The NASA GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md. created the animation from images obtained by the Geostationary Operational Environmental Satellite, GOES-13. The GOES series of satellites are operated by NOAA.
The GOES-13 animation includes visible and infrared imagery from GOES-13 that runs from June 4 at 1745 UTC (1:45 p.m. EDT) to June 6 at 1445 UTC (10:45 a.m. EDT). On June 4, the plume was blowing to the southeast. Through June 5 and 6, the winds shifted and viewers of the animation can see the plume start turning in a counterclockwise motion to the east, northeast and then north as high pressure moves in (In the south high pressure system winds rotate opposite they way they do in the northern hemisphere, so they shifted the winds from southeast to the north.
A visible image was taken on June 8 at 18:30 UTC (2:30 p.m. EDT) by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Aqua satellite. The plume from the Puyehue-Cordón Caulle volcano in Chile has now expanded to the south and is now covering a much wider angle than earlier this week. The image shows the plume of ash now blowing to the east over Argentina in what almost appears to be a 90 degree triangle.
The MODIS Rapid Response Team is also located at NASA Goddard, and creates images from the MODIS instrument that flies aboard NASA's Aqua and Terra satellites.
According to MSNBC on June 8, flights in and out of Chile, Argentina and Buenos Aires, Brazil were suspended or delayed over the last several days and travelers should check with their airlines. The Associated Press and CBS News noted that the organization in Chile that monitors volcanic eruptions: the National Geology and Mines Service considers the eruption moderate so far, but it could change.
Meanwhile, satellite data from NASA and NOAA will help airlines determine the direction of the ash plumes and whether air travel can resume.

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...
