NASA/JAXA's TRMM Satellite passed over newborn Tropical Depression 1W after it came together in the Northwestern Pacific Ocean on January 13 and saw bands of moderate to heavy rainfall wrapping around the northern quadrant of the storm.
The Tropical Rainfall Measuring Mission or TRMM satellite is managed by both NASA and the Japan Aerospace Exploration Agency called JAXA.
TRMM can measure the rate in which rain is falling from its orbit over the Earth's tropics. When it passed over Tropical Depression 1W (TD1W) on January 13 at 0556 UTC (12:56 a.m. EST) data showed two large broken bands of thunderstorms north of the center of circulation that contained moderate to heavy rainfall where rain was falling at a rate of 1 inch to 1.2 inches (25 to 20 mm) per hour.
The bulk of rainfall was occurring over the west-northwestern quadrant.
On Jan. 13 at 1500 UTC (10 a.m. EST) TD1W had maximum sustained winds near 25 knots (28.7 mph/46.3 kph). It was located about 222 nautical miles (255.5 miles/411.1 km) east of Yap, near 8.9 north latitude and 141.8 east longitude. It was moving to the west-northwest at 8 knots (9.2 mph/14.8 kph).
The Joint Typhoon Warning Center expects TD1W to move in a west-northwesterly direction and intensify to tropical storm status on approach to the east central Philippines by January 17.

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...
