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 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.

Watch an Antarctic Minke Whale Feed in a First-of-Its-Kind Video

New research from the World Wildlife Fund is giving us a rare glimpse into the world of the mysterious minke whale. The WWF worked with Australian Antarctic researchers to tag minke whales with cameras for the first time, watching where and how the animals feed.

The camera attaches to the whale's body with suction cups. In the case of the video below, the camera accidentally slid down the side of the minke whale's body, providing an unexpected look at the way its throat moves as it feeds.

Minke whales are one of the smallest baleen whales, but they're still pretty substantial animals, growing 30 to 35 feet long and weighing up to 20,000 pounds. Unlike other baleen whales, though, they're small enough to maneuver in tight spaces like within sea ice, a helpful adaptation for living in Antarctic waters. They feed by lunging through the sea, gulping huge amounts of water along with krill and small fish, and then filtering the mix through their baleen.

The WWF video shows just how quickly the minke can process this treat-laden water. The whale could lunge, process, and lunge again every 10 seconds. "He was like a Pac-Man continuously feeding," Ari Friedlaender, the lead scientist on the project, described in a press statement.

The video research, conducted under the International Whaling Commission's Southern Ocean Research Partnership, is part of WWF's efforts to protect critical feeding areas for whales in the region.

If that's not enough whale for you, you can also watch the full 13-minute research video below:

AI Could Help Scientists Detect Earthquakes More Effectively

Thanks in part to the rise of hydraulic fracturing, or fracking, earthquakes are becoming more frequent in the U.S. Even though it doesn't fall on a fault line, Oklahoma, where gas and oil drilling activity doubled between 2010 and 2013, is now a major earthquake hot spot. As our landscape shifts (literally), our earthquake-detecting technology must evolve to keep up with it. Now, a team of researchers is changing the game with a new system that uses AI to identify seismic activity, Futurism reports.

The team, led by deep learning researcher Thibaut Perol, published the study detailing their new neural network in the journal Science Advances. Dubbed ConvNetQuake, it uses an algorithm to analyze the measurements of ground movements, a.k.a. seismograms, and determines which are small earthquakes and which are just noise. Seismic noise describes the vibrations that are almost constantly running through the ground, either due to wind, traffic, or other activity at surface level. It's sometimes hard to tell the difference between noise and legitimate quakes, which is why most detection methods focus on medium and large earthquakes instead of smaller ones.

But better understanding natural and manmade earthquakes means studying them at every level. With ConvNetQuake, that could soon become a reality. After testing the system in Oklahoma, the team reports it detected 17 times more earthquakes than what was recorded by the Oklahoma Geological Survey earthquake catalog.

That level of performance is more than just good news for seismologists studying quakes caused by humans. The technology could be built into current earthquake detection methods set up to alert the public to dangerous disasters. California alone is home to 400 seismic stations waiting for "The Big One." On a smaller scale, there's an app that uses a smartphone's accelerometers to detect tremors and alert the user directly. If earthquake detection methods could sense big earthquakes right as they were beginning using AI, that could afford people more potentially life-saving moments to prepare.
