Over the last couple of days, NASA satellite data from both the Tropical Rainfall Measuring Mission (TRMM) and Atmospheric Infrared Sounder (AIRS) that flies aboard Aqua detected powerful thunderstorms within Ma-on. Those thunderstorms contained heavy rainfall, falling at a rate of 2 inches/50 mm per hour. As NASA's Aqua satellite flew over Ma-on on July 14 (11:30 p.m. EDT on July 13), the Moderate Resolution Imaging Spectradiometer (MODIS) instrument captured a visible image of Typhoon Ma-on moving over the Northern Mariana Islands.
This image was captured by the MODIS instrument that flies aboard NASA's Aqua satellite. It shows Typhoon Ma-on at 03:30 UTC on July 14 (11:30 p.m. EDT on July 13) moving through the western North Pacific Ocean, over the Northern Mariana Islands.

At 1500 UTC (11 a.m. EDT/1 a.m. Guam local time) on July 14, Typhoon Ma-on had maximum sustained winds near 95 knots (109 mph/175 kmh). It was located over the northern Marianas islands, about 250 nautical miles southeast of Iwo To, Japan near 20.3 North and 144.5 East. It was moving west near 11 knots (13 mph/20 kmh).
The National Weather Service flood advisory for today, July 14 at 11 a.m. Eastern Daylight Time (1 a.m. local time/Guam on July 15) noted that "additional rainfall amounts of 1 to 2 inches are possible during the next several hours. Recent heavy rains have left the ground saturated."
High surf conditions are also expected in Guam, Rota, Tinian and Saipan over the next several days. At 3:50 p.m. CHST (local time in Guam) on July 14 the National Weather Service (NWS) also issued a high surf advisory that will remain in effect through 6 a.m. (local time) on Sunday, July 17 as Ma-on passes through the region. The NWS advisory states that "Surf will build to hazardous at 7 to 9 feet along west facing reefs tonight and Friday. Surf will peak at 9 to 11 feet Friday night and Saturday, and should fall below 9 feet on Sunday." Beaches and exposed reefs are places to avoid through the advisory period, especially those facing the west as Ma-on continues to move in that direction. Rip currents are also possible.
There is also a small craft advisory in effect for the coastal waters of Guam, Rota, Tinian and Saipan until 6 p.m. (local time) Sunday as seas are expected to rise to 10 to 12 feet accompanied by winds between 20 and 25 knots (23-29 mph/37-46 kmh) through Saturday night.

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...
