NASA's Aqua satellite flew over John on Sept. 3 at 2041 UTC (4:41 p.m. EDT) during its brief time as a tropical storm and noticed convection (rising air that forms thunderstorms that make up the storm) and coldest cloud top temperatures seemed to be limited to the northeastern and southwestern quadrants of the storm. As John continued to move north into cooler waters the convection tapered off, and the development of strong thunderstorms diminished.

By Tuesday, September 04, 2012 at 2 a.m. EDT, there was no sign of strong convection in John and the storm had become "a swirl of low- to mid-level clouds," according to the National Hurricane Center.
At 11 a.m. EDT today, Tropical Depression John's maximum sustained winds were near 35 mph (55 kmh) and the storm is weakening. It was centered about 420 miles (620 km) west of the southernmost tip of Baja California, near 23.5 North and 116.5 West. John was moving to the northwest near 14 mph (22 kmh) and is expected to keep moving in that general direction while slowing over the cooler waters.
John's fame is fleeting as the tropical depression is expected to become a remnant area of low pressure later today, Sept. 4.

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...
