Another instrument on NASA's Aqua satellite measured the cloud top temperatures of Tomas' thunderstorms, and revealed very high, cold thunderstorms (as cold as minus 63 degree Fahrenheit) surrounding Tomas' 34-mile in diameter-wide-eye. The Atmospheric Infrared Sounder (AIRS) instrument showed forecasters that the thunderstorm "engine" in Tomas' center was very powerful with strong thunderstorms, dropping heavy rainfall.
Tomas has already caused damages for residents of the northern Fiji islands. Damage reports are still coming in, but power losses and flooding have been reported. Evacuations have taken place in Labassa, Wainiika, Nuku and Vatu because of flooding. Other reports indicate that schools and government buildings have been closed. Tourists were evacuated and flights have been temporarily canceled to and from Fiji's main airport.
At 0828 UTC March 15 (4:28 a.m. EDT), Cyclone Tomas was packing maximum sustained winds near 120 mph (105 knots). The center of the storm was approximately 200 nautical miles northeast of Nadi, Fiji, near 16.1 South and 179.5 West. Tomas is moving south at 7 mph (6 knots). Tomas' estimated minimum central pressure was 930 millibars.
Cyclone-force winds extend 40 miles out from the center, while tropical storm-force winds extend out 150 miles from the center, making the storm 300 miles in diameter. Tomas' eye is 30 nautical miles (34 miles) in diameter.
Infrared satellite imagery shows that Tomas has maintained its banding or wrapping around of thunderstorms around the storm's low-level center of circulation. As Tomas continues to track in a southerly direction over the next day and a half, it is forecast to intensify a little (due to the warm ocean waters it will be passing through), then will run into increasing wind shear which will weaken the storm.
The Fiji Meteorological Service issued a forecast track map for Tomas at: www.met.gov.fj. The forecast brings Tomas's center between Cicla, Lakebda, and Kabrana to the east, and Labesa, Suva and Kadavu to the west over the next day. For the latest advisories and warnings from the Fiji Meteorological Service: http://www.met.gov.fj/advisories.html. Residents of the southern Fiji islands should monitor watches and warnings.

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...
