NASA's Aqua satellite passed over Tropical Storm Guchol on June 12 at 0335 UTC and captured a near-infrared image of the storm from the Atmospheric Infrared Sounder (AIRS) instrument. The infrared imagery indicates that convection (rising air that forms thunderstorms) and thunderstorms are consolidating over the low-level circulation center.

Two tightly curved bands of thunderstorms are wrapping into the low-level center from the northeastern and southwestern quadrants of the storm. Satellite imagery indicates that dry air along the northern edge of the storm is preventing thunderstorm formation, which accounts for the slow development of the storm, and the smaller size.
On June 12 at 1500 UTC (11 a.m. EDT/U.S.), Guchol, formerly known as Tropical Depression 05W, has maximum sustained winds near 65 knots (~75 mph/120.4 kph). It is located about 225 nautical miles east of Yap, near 9.7 North and 141.7 East. It is moving to the west at 7 knots (8 mph/13 kph). A tropical storm warning is in effect for Fais and Ulithi in Yap State, Micronesia.

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...
