Facebook seems to have settled the class-action suit brought by five users in order to keep other plaintiffs from joining the suit, which could have exposed the social media behemoth to much higher damage or settlement costs. Most important to Facebook, it did not have to agree to stop Sponsored Stories, which means millions of people who do not pay attention to privacy issues could still be used in the advertisements.

Ignorance Is Bliss

Researchers have clocked light beams made of "twisted" waves carrying 2.5 terabits of data - the capacity of more than 66 DVDs - per second.

The technique relies on manipulating what is known as the orbital angular momentum of the waves.

Recent work suggests that the trick could vastly boost the data-carrying capacity in wi-fi and optical fibres.

The striking demonstration of the approach, reported in Nature Photonics, is likely to lead to even higher rates.

I usually would not mention something like this, but in the 1970s I drew up wild schemes in which the light out of laser beams got twisted and "resonating at a reducing amplitude but increasing frequency", by using the long narrowing ends of hyperbolically shaped crystals... On paper it looked feasible... Who knows...
