On Dec. 5, 2012, Bopha crossed over Palawan and entered the South China Sea after crossing over the southern Philippines' Mindanao region, leaving death and destruction in its wake. According to Reuters news reports on Dec. 5, at least at total of 283 people were killed and hundreds remain missing in the Philippines. The hardest-hit province in Mindanao was Compostela, where flood waters and mudslides swept through the town and killed at least 150 people. Homes were destroyed, roads were flooded and washed out, and it was estimated that as much as 80 percent of plantations were destroyed.
On Dec. 2, 2012, NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Super Typhoon Bopha. Data from the overpass was used to create a 3-D image that showed that the inner eyewall was being replaced by an outer eyewall, something that typically happens in major typhoons. There was also a "hot tower" thunderstorm reaching 12 kilometers (7.4 miles) high, located north of the center of circulation. NASA research indicates that whenever a "hot tower" is spotted in a tropical cyclone, the storm usually intensifies within 6 hours. The data also indicated the highest, most powerful thunderstorms were around the center where cloud top temperatures were as cold as -90 Celsius (-130F).
On Dec. 5 at 0517 UTC (12:17 a.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared view of Typhoon Bopha's cloud-top temperatures as it was exiting Palawan and moving into the South China Sea. The AIRS data identified areas of bitterly cold cloud-top temperatures of 210 kelvin (-63C/-81F) where the strongest thunderstorms, with highest cloud tops, and heaviest rainfall were found. One area was located over the South China Sea and the other over northern Palawan at the time of the image.
Three minutes later, another instrument aboard Aqua captured a visible image of Typhoon Bopha. The image revealed that Bopha's clouds covered the entire island of Palawan, and where the AIRS instrument revealed the coldest cloud top temperatures, those areas of clouds appeared the brightest white in the visible image, because they were higher than the surrounding clouds, and cast shadows on the lower clouds. The strongest thunderstorms have waned around the center of circulation during the early part of Dec. 5, although a tightly curved band of thunderstorms remained along the western and northern quadrants.
On Dec. 5 at 1500 UTC (10 a.m. EST) Bopha's maximum sustained winds were near 75 knots (86 mph/139 kph). It was located near 11.5 north latitude and 117.4 east longitude, about 270 nautical miles southwest of Manila, Philippines. Bopha is moving to the northwest near 11 knots (12.6 mph/20 kph) and is expected to slow down in the South China Sea.
Bopha is expected to continue tracking generally west-northwest into the South China Sea and become quasi-stationary over the next couple of days.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

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...
