NASA's Aqua satellite passed over Tropical Depression 02W (TD02W) as it was coming together and soaking provinces in Mindanao and the Palawan province of Luzon. The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard Aqua captured an infrared image of the depression at 0541 UTC (12:41 a.m. EST). The AIRS image showed very cold cloud top temperatures, colder than -63F (-52C) over Mindanao and stretching west to Palawan. Cloud top temperatures that cold are indicative of the potential to drop heavy rainfall.

AIRS infrared satellite imagery showed a very poorly organized and ill- defined low-level circulation center. The convection (rising air that forms thunderstorms that make up the depression) appears disorganized in the northern quadrant of the storm.
On Feb. 19 at 0900 UTC, the low pressure area designated as System 98W organized into a tropical depression and was renamed "02W." Tropical Depression 02W formed south of Mindanao, the Philippines. TD02W is referred to locally in the Philippines as "Tropical Depression Crising."
As a result of the formation of the depression, warnings were posted by PAGASA for many areas in the Philippines. Public storm warning signal #1 was posted for the following provinces of Mindanao: Davao del Norte and Sur and Oriental, Samal Island, Compostela Valley, the southern part of Surigao del Sur, Agusan del Sur, Bukidnon, Lanao del Norte and Sur, North Cotabato, Maguindanao, Sultan Kudarat, South Cotabato, Sarangani, Misamis Occidental, Zamboanga del Norte and Sur and& Sibugay, Basilan, Sulu and Tawi-Tawi. In addition, Signal #1 is now in effect for the south of the Palawan province of Luzon.
On Feb. 19 at 1500 UTC (10 a.m. EST), TD02W had maximum sustained winds near 25 knots (28.7 mph/46.3 kph). TD02W was located near 6.5 north latitude and 122.9 east longitude, just 55 nautical miles (63.3 miles/102 km) east-southeast of Zamboanga, Philippines. RD02W is moving to the west-northwest at 9 knots (10.3 mph/16.6 kph).
TD02W is currently experiencing moderate vertical wind shear, as high as 20 knots (23 mph/37 kph) which is keeping the depression from getting better organized. That is expected to change, however, once TD02W moves west into the South China Sea.
Forecasters at the Joint Typhoon Warning Center expect TD02W to move to the west-northwest, and pass just south of Palawan's southern tip before moving into open waters of the South China Sea where it is expected to become more organized.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
