You've probably heard of Prisma, one of the hottest apps this year. Downloaded more than 50 million times since June and powered by artificial intelligence, it uses filters to transform any photo into a stunning work of art evocative of say, Pablo Picasso or a Renaissance master. It's trending in the App Store: ranked fourth in the free photo and video category behind Snapchat, Instagram, and YouTube. But you've probably heard less about the Prisma bot with similar features and the same name, launched less than a month ago on Telegram. It's notable that one of today's most popular mobile apps waited only about a month before launching a bot, and it begs the question: Are bots replacing apps?

After the Eyjafjallajökull volcano erupted in Iceland in 2010, flight cancellations left Miranda Cheng stranded in Paris. While waiting for the ash to clear, Cheng, then a postdoctoral researcher at Harvard University studying string theory, got to thinking about a paper that had recently been posted online. Its three coauthors had pointed out a numerical coincidence connecting far-flung mathematical objects. "That smells like another moonshine," Cheng recalled thinking. "Could it be another moonshine?" She happened to have read a book about the "monstrous moonshine," a mathematical structure that unfolded out of a similar bit of numerology: In the late 1970s, the mathematician John McKay noticed that 196,884, the first important coefficient of an object called the j-function, was the sum of one and 196,883, the first two dimensions in which a giant collection of symmetries called the monster group could be represented.

For the past two days, Samsung has been talking about its Galaxy Note 7's iris scanner on its online newsroom, highlighting the reasons why this new mobile security feature could be a big game changer in the mobile industry. Just yesterday, the South Korean-headquartered company discussed how the iris scanning technology is making Samsung Pass even more secure. Samsung Pass is part of Knox, the comprehensive security platform of Samsung's recent handsets. Pass previously centered on fingerprint recognition via the fingerprint scanner as a means of enhancing the identity verification process of the phone itself and certain apps. With the addition of the iris scanner, Samsung claims that the Note 7's security has reached the ultimate level thanks to this advanced biometric authentication that does not require IDs or passwords for identity authentication.

Start-ups are hoping new artificial intelligence (AI) techniques that make searching the web more like talking to a friend will help them take on Google. Companies are developing search software that understands natural language, something that has typically been difficult for computers to do. Israel-based start-up Twiggle has come up with a solution specifically for e-commerce. The company, backed by Chinese online shopping giant Alibaba, is trying to help make searching sites for items a lot easier. "We are trying to bring the search experience as close as possible to the positive aspect of the in-store experience," Amir Konigsberg, chief executive of Twiggle, told CNBC in a phone interview on Wednesday.

If former Marine and entrepreneur Sean Bielat has his way, the law enforcement officer tentatively approaching a vehicle in the future after making a traffic stop won't be an officer at all. Rather, those are the kind of interactions -- fraught with uncertainty, potentially dangerous -- that seem to him to make perfect sense for one of his robots to deal with instead. DON'T MISS: I built a Wi-Fi paradise and all I needed was one device Bielat is the CEO of Endeavor Robotics, a privately held ground robotics company that in April spun out of Mass.-based iRobot and is focused on the defense, public safety and energy and industrial markets. It's a young company, but already Endeavor has delivered some 6,000 robots to customers, everything from a roughly five-pound throwable robot perfect for surveillance and reconnaissance up to its 500-pound beast called the Kobra. The Kobra has a 12-foot arm and can lift loads of up to a couple hundred pounds.
