NASA-NOAA's Suomi NPP satellite spotted Tropical Storm Omais just off-shore, and east of the big island of Japan.
On Aug. 7 at 11:05 p.m. EDT (Aug.8 at 3:05 a.m. UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible light image of Omais in the northwestern Pacific Ocean. The VIIRS image showed that the bulk of Omais' thunderstorms were north and west of the center of circulation. Omais' center was visible in the image, and the southeastern quadrant seems to be devoid of thunderstorm development.
A false-colored infrared image from the AIRS instrument aboard NASA's Aqua satellite showed Tropical Storm Omais' coldest cloud tops and strongest thunderstorms over northern Japan on Aug. 8. The image also showed that the storm is elongating, which is a sign of weakening. The image was created at NASA's Jet Propulsion Laboratory in Pasadena, California.
On Aug. 8 at 11 a.m. EDT (3 p.m. UTC) Omais' maximum sustained winds were near 46 mph (40 knots/74 kph). It was centered near 36.2 degrees north latitude and 144.7 degrees east longitude, about 230 nautical miles east of Yokosuka, Japan. Omais was moving to the north at 11.5 mph (10 knots/18.5 kph).
The Japan Meteorological Agency has posted warnings and watches for northern Japan. To see the warning areas, visit: http://www.
The Joint Typhoon Warning Center expects Omais to curve to the northeast while remaining to the east of the Kuril Islands and transition into an extra-tropical storm over the next couple of days.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
