On January 25 at 00:59 UTC (8:59 p.m. EST on Jan. 24), the Atmospheric Infrared Sounder (AIRS) instrument captured data that was used to create infrared and visible images at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The images showed Cyclone Wilma had strengthened overnight and now has a visible eye.
Tropical cyclone Wilma was seen by the TRMM satellite shortly after attaining hurricane intensity on Jan. 24, 2011, at 2128 UTC. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches (20 and 40 mm) per hour. Credit: NASA/SSAI, Hal Pierce
AIRS Infrared imagery showed strong, very cold thunderstorm cloud tops around Wilma's center of circulation. The cloud tops were as cold as or colder than -63 Fahrenheit (-52 Celsius) indicating strong convection (rapidly rising air that creates the thunderstorms that power a tropical cyclone). Animated infrared satellite imagery showed a 25 nautical mile (29 mile/46 km) diameter ragged eye with tightly-curved banding of thunderstorms wrapping into the center.AIRS instrument data also showed what appears to be a large "tail" from Wilma's center, stretching several hundred miles (kilometers) to the northeast of the storm's center.
On January 25 at 0900 UTC (4 a.m. EST), Tropical Cyclone Wilma had maximum sustained winds near 85 knots (97 mph/157 km/hr). It was located about 360 nautical miles southeast of Nadi, Fiji near 22.0 South and 178.2 West. It was moving southwestward near 24 knots (27 mph/ 44 km/hr).
A Tropical Cyclone Warning is in force for areas of Tonga and for areas of Fiji. On its projected path, Tropical Cyclone Wilma is expected to pass about 124 miles (200 km) south-southeast of Ono-i-lau by midnight local time tonight.
Republic of the Fiji Islands is an island nation in Melanesia in the South Pacific Ocean about 1,243 miles (2,000 km) northeast of New Zealand's North Island. Vanuatu is located to the west, and New Caledonia is located to the southwest. Tonga is located east of Fiji. Tonga is an archipelago comprised of 176 islands scattered over 270,000 square miles (700,000 square kilometers).
Wilma is forecast to continue moving southwest parallel to Fiji and New Caledonia as it makes its way toward New Zealand. On January 28 it is forecast to change course and head southeast bringing rains and gusty winds to northern New Zealand.

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.
