High clouds had moved over Super Typhoon Nuri's eye early on Nov. 4 when NASA's Terra satellite passed overhead as the storm was undergoing eyewall replacement.
Eyewall replacement occurs when the thunderstorms that circle the eye of a powerful typhoons or hurricanes are replaced by other thunderstorms. Basically, a new eye begins to develop around the old eye. Many intense hurricanes undergo at least one of these eyewall replacements during their existence.
On Nov. 4 at 01:55 UTC (8:55 p.m. EST) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite captured a visible image of Super Typhoon Nuri as clouds moved into its eye.
The MODIS image showed a large, thick band of thunderstorms spiraling into the eye that stretched to the south of the center. The extent of the clouds in the northern quadrant appeared to be just east of Japan.
A microwave image from NASA/JAXA's Tropical Rainfall Measuring Mission showed that Nuri is undergoing eyewall replacement, although the previously observed eye feature has become cloud filled and less defined.
By 1500 UTC (10 a.m. EST), Nuri's maximum sustained winds had dropped to 120 knots (138.1 mph/222.2 kph). Nuri was centered near 23.5 north latitude and 136.6 east longitude, about 293 nautical miles (337.2 miles/542.6 km) west-southwest of Iwo To and has tracked northeastward at 12 knots (13.8 mph/22.2 kph).
NOAA's National Weather Service office on Iwo To (also known as Iwojima) current conditions at 10 a.m. EST on Nov. 4 reported winds from the southeast were sustained at 22 mph. Skies were mostly cloudy and the air temperature was 78F (26C). Heavy rain showers were reported on Nov. 3.
Nuri is passing to the west of Iwo To and is expected to move to the northeast and parallel the big island of Japan over the next couple of days while weakening. Within two days the storm is expected to weaken just below hurricane-force.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
