NASA's Aqua satellite passed over Tropical Storm Nadine early on Sept. 13 and saw several factors that indicated the storm was still struggling to achieve hurricane status.

Infrared data from the Atmospheric Infrared Sounder (AIRS) that flies aboard Aqua found the strongest thunderstorms with very cold cloud temperatures (colder than -63F/-52C) were being pushed east of Nadine's center by wind shear.
Although Nadine is expected to reach hurricane status later on Sept.13 or Sept. 14, the storm did not yet develop an eye. The AIRS infrared image also showed that Nadine's cloud pattern was not symmetric, and a tropical cyclone needs symmetry to intensify. If the moderate southwesterly wind shear relaxes, Nadine will have a better chance of intensifying. Satellite data also suggests that intrusion of mid-level dry air, which is also sapping Nadine's strength.
At 11 a.m. EDT on Sept. 13, Tropical Storm Nadine's maximum sustained winds were just under hurricane strength, near 70 mph (110 kmh). The National Hurricane Center noted that Nadine could become a hurricane later on Sept. 13 (today). The center of Tropical Storm Nadine was located near latitude 22.6 north and longitude 52.2 west, about 770 miles (1,235 km) east-northeast of the Northern Leeward Islands. Nadine is moving toward the northwest near 16 mph (26 kmh) and the National Hurricane Center expects Nadine to turn to the north-northwest and later to the north.Text credit: Rob Gutro

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
