Add / Remove Winter weather can wreak havoc with flight schedules. We recently wrote about a de-icing concrete that could be used at airports to prevent cancellations, and now researchers at the University of Michigan have developed an ice-repellent spray , which could be applied to airplanes — and other machinery — to prevent them from freezing over. The “icephobic” coating is made of common synthetic rubbers and could provide a green alternative to chemical melting agents or costly defrosting systems. When sprayed onto a solid surface, the substance, because of its rubbery texture, uses interfacial cavitation to repel the ice. As a result, it is significantly easier to remove ice that forms on the surface because the two materials do not bond to each other. The researchers envision the spray being used on freezers, wind turbines or oil rigs. What other applications are there for the “icephobic” coating?

Janko Roettgers reports for Variety: Sony is launching its 4K movie streaming service called Ultra next month: Consumers will be able to buy movies from the service, and stream to supported Sony 4K TV sets, starting April 4. The new service will offer 4K HDR movies to stream, including extras that have previously been able only on physical discs. Ultra ties into UltraViolet, the cloud locker service backed by Sony.
