Super resolution forensic video analysis deblur, deblurring enhancement
Security footage can be enhanced by several different techniques to reveal information that would at first glance seem impossible to retrieve.
It was most famously used in blurry helicopter footage of the LA riots to convict those who beat Reginald Denny, as referred to in this summary on slide 17, (and this article)
It was used to find the Boston bombing suspect:
Impressive results in the last few seconds of the video.

In the courtroom, the jury needs to understand exactly what was done to enhance the video and the original video has to be authenticated and preserved.

This example elaborates the multiple mathematical steps to combine multiple images mapped onto a face template then averaged into a higher resolution composite that's much better than AI. At 6:30 he shows how much better his result is than an AI-generated best guess from very pixelated images.

Do we trust our computer chips too much?
This article takes about 15 minutes to read, but talks about how easily the computer chips we trust for ever-more important roles in our lives are prone to attack, and vulnerable.

UBC's New Student Union Building

How Jump On Flyaways aims to be the Uber of the skies
I agree there are other models for "optimizing unused assets" like car2go, airBnB, and Uber, but I'd be surprised if airline flights are something people are willing to take a bet on if these services have to cancel flights a week beforehand if their plane isn't filled. There are just too many associated costs with travel that you'd be giving up, like hotels and excursions, and the alternative to a missed flight is expensive. (If you fail to find a carshare vehicle, you can just get a bus or a taxi. But a last-minute flight is a very expensive backup option if this flight falls through.)
I don't think I'll buy shares...

Call it ride-hailing for the jet set...
"...In some cases, the flights end up costing the same or less than first-class tickets on a commercial airliner...
"...Among the start-ups is Magellan Jets, which offers a subscription-based model where passengers can buy blocks of flight time and then get matched to planes through an iPhone app...
"...Another start-up is BlackJet, which pairs customers with empty seats on nearby private aircraft. Formerly called GreenJets, BlackJet notes that its tickets cost about the same as first-class airline seats. But the similarities end there, said BlackJet’s chief executive, Dean Rotchin. Private jets “are much more reliable,” he said, noting that about half of BlackJet’s customers are business travelers. “It takes off when it’s supposed to take off. You drive up to the airplane. Fifteen minutes and you’re in the air...”
Shrimp containing antibiotics
In their tests, Consumer Reports found antibiotics in 11 of 342 packages of shrimp.
Oxytetracycline
Enrofloxacin
Sulfa
Maybe the common allergies to shrimp are actually allergies to antibiotics!

Here's the mass production where they're often produced, in Thailand.

This Futuristic Concrete Heals Itself With Built-In Bacteria
Cool! Dormant bacteria awaken if a crack develops in the concrete and water seeps in; the bacteria help form new concrete that seals the hole.
