Manufactured sapphire is incredibly strong and scratch resistant. Now falling costs and technology improvements could make it competitive with glass.
Manufactured sapphire—a material that’s used as transparent armor on military vehicles—could become cheap enough to replace the glass display covers on mobile phones. That could mean smartphone screens that don’t crack when you drop them and can’t be scratched with keys, or even by a concrete sidewalk.

JVC Builds The First 8K Projector: It Costs $260,000
The JVC projector reaches a resolution of 8K by using two 120 Hz images, one of them being slightly bent vertically.
The JVC DLA-VS5800 projector can give you the impression of a very big image without the huge resolution, but buyers will have to wait at least until 2016 to get more 8K content. The first 8K digital transmission tests are scheduled only in 2016.
Canon’s New Baby DSLR may be World’s Smallest, but isn’t Short on Performance
We’ve been hoping Canon would release a follow-up to its EOS M soon, but instead of a new highly compact mirrorless camera, Canon gave us shrunk-down DSLR. The camera weighs 14.4 ounces, and it’s 25-percent smaller and 28-percent lighter than the outgoing Rebel T4i. While it’s still larger than a mirrorless model, the SL1 is essentially a traditional DSLR stuffed into a much smaller body, but with newly enhanced features.
