NASA satellites have been providing data on Tropical Cyclone Winston in the Southwestern Pacific, and watched the storm over the past couple of days as it weakened to a tropical storm. Today, Feb. 16, Winston regained hurricane-force and threatens Tonga and American Samoa.
On Feb.16 a gale warning was in effect for Niue. In Tonga, a storm warning was in effect for Vavau and a gale warning was in effect for Ha'apai, Niuafo'ou and Niuatoputapu.
On Feb. 16 at 1500 UTC (10 a.m. EST) Tropical cyclone Winston's maximum sustained winds had increased to hurricane-force after spending several days as a tropical storm. Winds were near 65 knots (74.8 mph/120.4 kph). Winston was centered near 17.9 degrees south latitude and 173.6 degrees west longitude, about 273 nautical miles (314 miles/505 km) southwest of Pago Pago, American Samoa. Winston was moving to the northeast at 10 knots (11.5 mph/18.5 kph).
On Feb. 16 the Atmospheric Infrared Sounder (AIRS) instrument aboard Aqua saw cloud top temperatures exceeding -63 degrees Fahrenheit (-53 degrees Celsius) around the 23 nautical-mile wide eye. Storms with cloud tops that cold are very high into the troposphere and have the capability of producing heavy rainfall.
The Joint Typhoon Warning Center noted "Winston is currently positioned in a good environment for intensification with favorable sea surface temperatures and low vertical wind shear.
JTWC expects Winston to move northeast and start to re-strengthen. The storm is forecast to peak at 100 knots (115.1 mph/185.2 kph) by Feb. 17 and 18, south of American Samoa, before turning back west.

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.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
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...
