University of Stuttgart researchers used 3D printing to fabricate a tiny three-lens camera that fits on the end of an optical fiber no wider than two human hairs. Eventually, the technology could lead to a new kind of very thin endoscope for looking inside the human body. According to the researchers, the camera delivered “high optical performances and tremendous compactness.” From Phys.org : (The camera) can focus on images from a distance of 3.0 mm, and relay them over the length of a 1.7-metre (5.6-foot) optical fibre to which it is attached. The “imaging system” fits comfortably inside a standard syringe needle, said the team, allowing for delivery into a human organ, or even the brain. “Endoscopic applications will allow for non-invasive and non-destructive examination of small objects in the medical as well as the industrial sector,” they wrote (in their scientific paper). Below, the lens (blue) was fabricated directly on the optical fiber (red). The fiber and camera are emerging from a hollow, 27 gauge syringe needle:

Khari Johnson, writing for VentureBeat:A bot made to challenge traffic tickets has been used more than 9, 000 times by New Yorkers, according to DoNotPay maker Joshua Browder. The bot was made available to New Yorkers in March. In recent years and decades, residents of The Big Apple have seen a persistent increase in traffic fines. A record $1.9 billion in traffic fines was issued by the City of New York in 2015. Since the first version of the bot was released in London last fall, 160, 000 of 250, 000 tickets have been successfully challenged with DoNotPay, Browder said. “I think the people getting parking tickets are the most vulnerable in society, ” said Browder. “These people aren’t looking to break the law. I think they’re being exploited as a revenue source by the local government.” Browder, who’s 19, hopes to extend DoNotPay to Seattle this fall. Read more of this story at Slashdot.
