The Tropical Rainfall Measuring Mission (TRMM) satellite is managed by both NASA and the Japanese Space Agency. Using TRMM data, 3-D images of Cyclone Jasmine were created at NASA's Goddard Space Flight Center in Greenbelt, Md.
The TRMM satellite traveled directly above tropical cyclone Jasmine in the South Pacific Ocean on February 8, 2012 at 2156 UTC (4:56 p.m. EST). Jasmine was classified as a powerful category 4 on the Saffir Simpson Scale with wind speeds of 115 kts (~132 mph) at its peak intensity but had started to weaken at the time of this pass.
A 3-D image was created using data from TRMM's Precipitation Radar (PR). The 3-D cutaway image revealed the funnel shaped surface of Jasmine's eye. TRMM PR data also showed that heights of Jasmine's tallest storms then reached to heights of about 11.5 km (~7.1 miles).
Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that intense thunderstorms in bands wrapping around Jasmine's large circular eye were dropping rain at a rate of over 50mm/hr (~2 inches). This was a daytime pass so the rainfall analysis was overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument.
Infrared imagery from instruments like the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite revealed that cloud top temperatures in Jasmine have been warming since early morning on February 9, 2012. That's an indication that the system is losing strength and the cloud tops are falling.
Jasmine is a small cyclone, only about 90 nautical miles (103.6 miles/166.7 km)in diameter, and the eye is about 20 nautical miles (23.2 miles/37 km) wide.
On February 9, 2012 at 0900 UTC, Jasmine's maximum sustained winds were near 105 knots (120.8 mph/194.5 kph). Jasmine was about 275 nautical miles (316.5 miles/509.3 km) east-southeast of Noumea, New Caledonia near 28.8 South and 171.4 East. Jasmine is moving to the south-southeast around 10 knots (11.5 mph/18.5 kph).
Jasmine is expected to move over cooler waters and encounter drier air, two factors that will further weaken the storm.Text Credit: Rob Gutro

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.
