The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument flies onboard NASA's Aqua and Terra satellites and the MODIS instrument on each captured a storm when both satellites flew over them on August 21 after midnight (Eastern Daylight Time). The two MODIS images which featured Bolaven and Tembin over the Philippine Sea were combined by NASA's MODIS Rapid Response Team at the NASA Goddard Space Flight Center in Greenbelt, Md. to paint the entire tropical picture in the northwestern Pacific Ocean on August 21.
MODIS images from NASA's Terra and Aqua satellites on Aug. 21, 2012, at 04:45 UTC were combined to provide a complete picture of the two tropical troublemakers in the northwestern Pacific: Typhoon Tembin and Tropical Storm Bolaven.

Typhoon Tembin Tracking to Taiwan
Typhoon Tembin is also known as Typhoon Igme in the Philippines, where it is still the cause for active warnings on Aug. 21. Public storm warning signal #1 remains in effect for the Batanes group of islands on Aug. 21. At 0900 UTC (5 a.m. EDT) on Aug. 21, Typhoon Tembin had maximum sustained winds near 110 knots (126.6 mph/203.7 kmh). Typhoon-force winds extended out to 30 nautical miles (34.5 miles/55.5 km) from the center, while tropical-storm-force winds extended out 100 nautical miles (115 miles/185 km) from the center, making Tembin over 200 nautical miles (230 miles/370 km) wide.
Tembin was located about 325 nautical miles (374 miles/602 km) southeast of Taipei, Taiwan, near 21.0 North latitude and 125.4 East longitude. Although Tembin is currently moving to the north-northeast, the Joint Typhoon Warning Center forecasts Tembin to intensify and take a western turn and head across Taiwan on Thursday, Aug. 23. After crossing Taiwan, Tembin is forecast to make a second landfall east of Hong Kong. A Sea Warning and Typhoon Warning is already in effect for Taiwan, as heavy rain and rough seas are expected to affect eastern Taiwan by Wednesday, Aug.22. The Central Weather Bureau indicated that Tembin will likely make landfall in the Yilan, Hualien or Taitung counties on the eastern coast.
Tropical Storm Bolaven Poised to Strengthen
Tropical storm Bolaven's maximum sustained winds were near 55 knots (63.2 mph/102 kmh) and the Joint Typhoon Warning Center expects it to strengthen into a typhoon over the next several days. At 0900 UTC (5 a.m. EDT) on Aug. 21, Bolaven was located about 390 nautical miles (449 miles/722 km) south of Iwo To, near 18.4 North latitude and 140.4 West longitude. Bolaven is crawling to the west-northwest at 4 knots (4.6 mph/7.4 kmh).
Bolaven appears on MODIS imagery as a smaller storm than Tembin. While Tembin is over 200 nautical miles (230 miles/370 km) in diameter, Bolaven is just about 100 nautical miles (115 miles/185 km) in diameter.
Bolaven is strengthening and is expected to become a typhoon as it heads northwest. It is currently expected to pass to the north of Taiwan around Aug. 25-26, 2012.

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“.

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.
