As predicted, Typhoon Songda intensified and was a super typhoon with wind speeds estimated at over 130 knots ( ~145 mph) when NASA's TRMM satellite passed directly over head on May 26, 2011 at 0806 UTC (4:06 a.m. EDT).
Songda had a circular eye with extremely heavy rainfall, particularly in the southeast quadrant. The red areas represent heavy rainfall (falling at about 2 inches/50 mm per hour). The yellow and green areas are moderate rainfall, falling at a rate between .78 to 1.57 inches (20 to 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce
The Tropical Rainfall Measuring Mission (TRMM) satellite captured the heavy rainfall rates within the super typhoon using TRMM's Visible and InfraRed Scanner (VIRS) instrument. The rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data showed that Songda had a circular eye with extremely heavy rainfall (as much as 2 inches/50 mm per hour) particularly in the southeast quadrant. TRMM's PR instrument data showed the concentric rain bands typical of powerful typhoons.
Warnings are in effect in the Philippines today. Public storm warning signal no 1 is in effect in the following provinces: Luzon: Catanduanes, Camarines Sur & Norte, Quirino, Albay, Aurora, Quezon Provinces, Polilio Island, Cagayan and Isabela.
At 1500 UTC (11 a.m. EDT) on May 26, Super Typhoon Songda (called Chedeng in the Philippines) had maximum sustained winds near 140 knots (161 mph/259 kmh). Typhoon-strength winds extend 45 miles out from the center, while tropical storm-force winds extend 155 miles from the center, making Songda over 300 miles wide.
Songda's center was 250 miles east-northeast of Manila, near 16.2 North and 125.1 East. It was moving northwest near 8 knots (9 mph/15 kmh). Songda is creating very rough and dangerous seas in Philippine Sea, with wave heights reaching 38 feet (11.5 meters).
Songda has intensified in favorable conditions as the forecasters at the Joint Typhoon Warning Center predicted. Songda may have reached its peak intensity and is forecast to start turning to the northeast and weaken because of increased wind shear.
Songda will then start to veer northeast and weaken due to deteriorating atmospheric conditions.
Taiwan has already posted Marine Warnings for May 27 and 28, forecasting wave heights to increase from 2 meters (~6.5 feet) to as much as 6 meters (~20 feet) on east-facing shorelines as Super Typhoon Sondga moves past (it will stay off-shore and track to the east of Taiwan). The current track from the Joint Typhoon Warning Center takes Songda over the island of Kadena on May 28, and then skirting the east coast of Japan as it continues on a northeasterly track over the weekend.

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...
