University of Ottawa researchers have done some groundbreaking work on lenses, using nanotechnology to develop so-called metalenses that dramatically shrink down optics. But lenses still rely on space to produce images and the researchers have presented the concept of an optical “spaceplate” that propagates light for a distance much longer than the plate thickness, enabling future imaging systems to shrink even further. A spaceplate can be used to miniaturize all kinds of devices that manipulate light. “It’s a possibly revolutionary development in the field of optical science,” suggests photography and camera news site PetaPixel.

Canada would like to levy a portion of online streaming services’ revenue to help fund domestic TV and music production. Netflix, Amazon Prime Video, Disney+ and others would be required to meet Canadian benchmarks, such as more content to serve its French-speaking and indigenous populations. According to Canada’s broadcast regulator, streaming services’ annual revenue is about $5 billion in Canadian dollars or $3.77 billion U.S. Canada seeks “nearly C$1 billion” a year from streaming services.
