On Monday, Oct. 1 at 1500 UTC (11 a.m. EDT), Tropical Depression 21W (TD21W) had maximum sustained winds near 25 knots. It was centered about300 nautical miles south of Hong Kong, near 17.4 North latitude and 114.8 East longitude. TD21W has tracked northward at 5 knots and is expected to curve to the northwest and west.
Infrared imagery from the AIRS instrument aboard NASA's Aqua satellite captured this image of Tropical Depression 21W as a developing low pressure area on Sept. 30. The purple areas indicate the most powerful thunderstorms with coldest cloud top temperatures.

On Oct. 1, 2012, infrared imagery from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite shows that the center of circulation is well-defined and the strongest thunderstorms are building in the southeastern quadrant of the storm and wrapping into the center.
The system has been quasi-stationary over the past 12 hours, because it is in a weak steering environment with nothing to push the storm in any direction.
Forecasters at the Joint Typhoon Warning Center expect that Tropical Depression 21W will start moving to the west and approach the central Vietnam coast by Oct. 6 or Oct. 7.

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...
