On June 21 at 1500 UTC (11 a.m. EDT) the newly weakened Tropical Depression 06W was located about 480 nautical miles east-southeast of Hanoi, Vietnam near 18.8 North and 113.8 East. Depression 06W's maximum sustained winds had decreased to 25 knots (28 mph/46 kmh). It was moving west-southwest at 9 knots (10 mph/17 kmh) and kicking up 11 foot-high waves in the South China Sea.
NASA's AIRS instrument on the Aqua satellite captured this infrared image of 06W on June 20 at 18:05 UTC (2:05 p.m. EDT) when it was still a tropical storm.

NASA's Atmospheric Infrared Sounder (AIRS) instrument that flies on the Aqua satellite captured an infrared image of 06W on June 20 at 18:05 UTC (2:05 p.m. EDT) when it was still a tropical storm. Since then, convection has become more scattered and winds have lessened. In addition, the low level center of the storm's circulation has become elongated due to wind shear. Elongation of a tropical cyclone is a sign of weakening.
Because of that wind shear, 06W is expected to barely maintain tropical depression strength before it makes landfall on Thursday, June 23 near Jhan Jiang, China.
The AIRS infrared image captures cloud top temperatures and the coldest temperatures appeared south of the center of circulation. Those cold cloud top temperatures represented the strongest thunderstorms in the tropical storm where rainfall rates could reach up to 2 inches / 50 mm per hour.
Because Tropical Depression 06W has begun moving to the west-southwest, the Joint Typhoon Warning Center has changed the forecast track and taken the depression farther south. The current landfall takes 06W just north of Hainan Island, China and then onto the mainland at the southwestern end of Guangdong province of Southern China.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
