On Oct. 24, 2012 at 0445 UTC (12:45 a.m. EDT) the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Storm Son-tinh. At the time of the image, Son-tinh's center was moving through the central Philippines, but its cloud cover extended north into Luzon. The image also showed that the strongest thunderstorms were east of the center, and were still over the Philippine Sea.

On Oct. 24 at 1500 UTC (11 a.m. EDT) Tropical Storm Son-tinh had maximum sustained winds near 35 knots (40.2 mph/64.8 kph). It was previously known as the low pressure area called "System 92W." Son-tinh was centered about 335 miles (385.5 mph/620.4 kph) southeast of Manila, Philippines and raining over much of the country. Son-tinh's center was near 10.7 North latitude and 125.2 East longitude and moving to the northwest at 17 knots (19.5 mph/31.4 kph).
The warnings continue in the Philippines as Son-tinh tracks west and toward the South China Sea. Public storm warning signal #1 was in effect on Oct. 24 (Eastern Daylight Time) for the for the Visayas province of Northern Samar, Antique, Iloilo, Southern Negros, Southern Cebu and Bohol; also for the Mindanao provinces of Surigao del Norte and Siargao Island. Public storm warning signal #1 was also in effect for the Luzon provinces of Camarines Sur, Albay, Sorsogon, Burias Island, Southern Quezon, Marinduque, Oriental and Occidental Mindoro, Calamian Group of Islands, Batangas, Lubang Island and Cuyo Island.
In addition, Public storm warning signal #2 was in effect for the Visayas provinces of Eastern and Western Samar; Leyte, Southern Leyte, Biliran Island, Camotes Island, Capiz, Aklan, Boracay Island, Northern Cebu, Bantayan Island and Northern Negros; and the Mindanao province of Dinagat Island. Public storm warning #2 was also in effect for the Luzon provinces of Masbate and Romblon.
The Joint Typhoon Warning Center expects Son-tinh to move northwest across the Philippine islands into the South China Sea and make a landfall on the Vietnamese coastline.

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...
