When NASA’s Aqua satellite flew over the Indian Ocean on May 13 at 0747 UTC (3:47 a.m. EDT), the Atmospheric Infrared Sounder (AIRS) instrument captured an image of both the remnants of Tropical Cyclone Jamala in the Southern Indian Ocean, and Tropical Cyclone Mahasen in the Northern Indian Ocean.

At the time of the AIRS image, cloud top temperatures in Jamala’s remnant continued to warm as the cloud tops continued to drop. The remnants appeared as an amorphous blob. Tropical Cyclone Mahasen appeared at least three times larger than Jamala’s remnants, and had much colder cloud top temperatures.
In fact, Mahasen had a large area of very strong thunderstorms with cloud top temperatures near -63 Fahrenheit (-52 Celsius) that stretched from its center northeast of Sri Lanka, southwest over northern Sri Lanka. Thunderstorms with cloud top temperatures that cold have been known to be heavy rain makers.
Tropical Storm Jamala dropped below tropical depression status on May 11. The Joint Typhoon Warning Center issued their final warning on Jamala on May 11 at 2100 GMT 5 p.m. EDT). Jamala's last noted location was near 10.6 south latitude and 88.3 east longitude, or 960 nautical miles (1,105 miles/ 1,778 km) east-southeast of Diego Garcia. Jamala was moving to the east at 7 knots (8 mph/13 kph), and its maximum sustained winds had dropped significantly down to just 25 knots (28.7 mph/46.3 kph).
Jamala is now a remnant low pressure area in the Southern Indian Ocean being battered by wind shear and dissipating.Text Credit: Rob Gutro

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
