Now named Cyclone Giovanna, this storm has reached Category One status on the Saffir-Simpson Hurricane/Cyclone scale with maximum sustained winds near 65 knots (~75 mph/120.4 kph) on February 10, 2012. It was located about 480 nautical miles (552 miles/889 km) northeast of La Reunion island, near 15.8 South and 61.2 East. It was moving to the west-southwest near 8 knots (9mph/15 kph).
The MODIS instrument on NASA's Terra satellite captured this image at 06:00 UTC (1 a.m. EST) on February 10, 2012, as Tropical Cyclone Giovanna moved through the Southern Indian Ocean. Although the visible image did not reveal an eye, infrared data did see the beginning of an eye. The thunderstorms around the center of circulation are higher than the surrounding clouds, and cast shadow on the lower surrounding clouds in this image.

When NASA's Terra satellite passed over Cyclone Giovanna, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard, captured a visible image at 06:00 UTC (1 a.m. EST) on February 10, 2012. Although the visible image did not reveal an eye, infrared data from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite did see the beginning of an eye. In the visible image, the thunderstorms around the center of circulation appeared higher than the surrounding clouds, and cast shadow on the lower surrounding clouds.
Forecasters at the Joint Typhoon Warning Center (JTWC) are still forecasting a landfall in east-central Madagascar. Residents of Madagascar need to prepare for the storm's arrival and expect heavy, flooding rainfall, very rough surf conditions and Cyclone-force winds.
On February 10 at 0900 UTC (4 a.m. EST) the JTWC forecast stated: "Due to the favorable environment, Giovanna is forecast to strengthen to a peak of 110 knots (~127 mph/~204 kph) within the next 36 hours." The system is expected to weaken significantly as it tracks across Madagascar; however, re-development is expected in the Mozambique Channel after 120 hours."Text Credit: Rob Gutro

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
