The Unbeatable Game: Dr. Nim

In the 1960s board game Dr. Nim, a pile of plastic can beat any human opponent. I, for one, welcome our 50-year-old plastic board game overlords.

Dr. Nim is less a board game than a simple computer; using mechanical controls called flip-flops, it implements the mathematical game of Nim. As mathematician/standup comedian Matt Parker shows in the video below, if you learn the simple rules of Nim (you don't need the board game to do it), you'll likely be able to bamboozle your friends, especially if they're tipsy—the game is inherently rigged in favor of the person setting the initial conditions of play (how many marbles there are and who goes first); beyond that you simply have to play a few rounds until your annoyed friends flip the table over and stomp off. While this game may not be "fun" in the traditional sense, it is certainly clever. Have a look:

For a bit more on the game itself and the math behind it, check the links in the video description. One of those links shows that the Computer History Museum has one of these board games in its collection; another points to the original instruction manual in PDF format (it's actually quite a read, going deep on binary arithmetic and boolean algebra as the thing wears on).

This Augmented-Reality App Makes the Hospital Experience Less Scary for Kids

Staying in a hospital can be a scary experience for kids, but a little distraction can make it less stressful. According to studies conducted by Alder Hey Children’s Hospital in Liverpool, UK, distracted patients have an easier time with their appointments and require less pain medication. Now, Co.Design reports that the hospital is releasing its own app designed to keep children entertained—and calm—from the moment they check in.

The Android and iOS app, called Alder Play, was designed by ustwo, the makers of the wildly popular smartphone game Monument Valley and the stress relief tool Pause. Patients can download the app before they arrive at the hospital, choosing a virtual animal buddy to guide them through their stay. Then, once they check into the hospital, their furry companion shows them around the facility using augmented-reality technology.

The app features plenty of fun scavenger hunts and other games for kids to play during their downtime, but its most important features are designed to coach young patients through treatments. Short videos walk them through procedures like blood tests so that when the time comes, the situation will feel less intimidating. And for each step in the hospitalization process, from body scans to gown changes, doctors can give kids virtual stickers to reward them for following directions or just being brave. There’s also an AI chatbot (powered by IBM’s Watson) available to answer any questions kids or their parents might have about the hospital.

The app is very new, and Alder Hey is still assessing whether or not it's changing their young hospital guests’ experiences for the better. If the game is successful, children's hospitals around the world may consider developing exclusive apps of their own.

This Pixel Kit Will Let You Play Tetris With Jellyfish DNA

Forget playing Tetris on your phone. Now you can play it with jellyfish DNA. Bixels is a DIY game kit that lets you code your own games using synthetic biology, lighting up a digital display with the help of DNA.

Its 8-by-8 pixel grid is programmed to turn on with the help of the same protein that makes jellyfish glow, called green fluorescent protein (GFP). But you can program it to do more than just passively shine. You can use your phone and the associated app to excite Bixels' fluorescent proteins and make them glow at different frequencies, producing red, blue, and green colors. Essentially, you can program it like you would any computer, but instead of electronics powering the system, it's DNA.

Two blue boxes hold Bixel pixel grids.

Researchers use green fluorescent protein all the time in lab experiments as an imaging agent to illuminate biological processes for study. With Bixels, all you need is a little programming to turn the colorful lights (tubes filled with GFP) into custom images or interactive games like Tetris or Snake. You can also use it to develop your own scientific experiments. (For experiment ideas, Bixels' creator, the Irish company Cell-Free Technology, suggests the curricula from BioBuilder.)

A screenshot shows a user assembling a Bixel kit on video.

A pixel kit is housed in a cardboard box that looks like a Game Boy.

Bixels is designed to be used by people with all levels of scientific knowledge, helping make the world of biotechnology more accessible to the public. Eventually, Cell-Free Technology wants to create a bio-computer even more advanced than Bixels. "Our ultimate goal is to build a personal bio-computer which, unlike current wearable devices, truly interacts with our bodies," co-founder Helene Steiner said in a press release.

You can buy your own Bixel kit on Kickstarter for roughly $118. It's expected to ship in May 2018.
