Advanced Tetris Gameplay

We've covered Tetris Shelving and Tetris Shower Stalls, but I think it's time to share some hardcore Tetris knowledge and killer gameplay.

The only resource you need is, which has a Tetris wiki containing a series of insanely technical articles about Tetris strategy, including: general technique, non-overstacking construction (also known as the thing I can never do right), the elusive zangi-move, and the nearly mind-blowing article on tactical rotation. Or perhaps you just want to play forever? It can be done. (Depending on how loosely you define "forever.")

I have to admit -- I'm mediocre at best at Tetris. Seeing all this material online makes me think that perhaps after years of study, I might master it...but I probably have better things to do. So what does a top-level Tetris game look like? I found the following video via the always-enjoyable Anarchaia. It starts out "pretty fast" and gets "crazy fast" around three minutes in. Towards the end (a bit past five minutes), the player enters some sort of invisible mode, where the stack of pieces (sorry, tetrominoes) is invisible. Invisible, I'm saying. And this player ("TGM HOLiC aka Jin8") still totally rocks it. Check it out, if you dare:

If that last video hasn't caused some kind of Tetris-induced panic attack or organ failure, you'll probably like this one.

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.

If you're used to fighting virtual zombies or flying spaceships on your computer, a new series of games available on Foldit may sound a little unconventional. The object of the Aflatoxin Challenge is to rearrange protein structures and create new enzymes. But its impact on the real world could make it the most important game you've ever played: The scientists behind it hope it will lead to a new way to fight one of the most ruthless causes of liver cancer.

As Fast Company reports, the citizen science project is a collaboration between Mars, Inc. and U.C. Davis, the University of Washington, the Partnership for Aflatoxin Control in Africa, and Thermo Fisher Scientific. The team's online puzzles, which debuted on Foldit earlier this month, invite the public to create a new enzyme capable of finding and destroying carcinogens known as aflatoxins.

Aflatoxins form when certain fungi grow on crops like corn, nuts, and grains. Developing countries often don't have the resources to detect it in food, leaving around 4.5 billion people vulnerable to it. When people do eat food with high aflatoxin levels unknowingly, they can contract liver cancer. Roughly a quarter of all liver cancer cases around the world can be traced back to aflatoxin exposure.

The toxin's connection to agriculture is why the food giant Mars is so interested in fighting it. By working on a way to stop aflatoxins on a molecular level, the company could prevent its spread more efficiently than they would with less direct methods like planting drought-resistant crops or removing mold by hand.

The easiest way for scientists to eradicate an aflatoxin before it causes real harm is by making an enzyme that does the work for them. With the Aflatoxin Challenge, the hope is that by manipulating protein structures, online players will come up with an enzyme that attacks aflatoxins at a susceptible portion of their molecular structure called a lactone ring. Destroying the lactone ring makes aflatoxin much less toxic and essentially safe to eat.

The University of Washington launched Foldit in 2008. Since then, the online puzzle platform has been used to study a wide range of diseases including AIDS and Chikungunya. Everyone is welcome to contribute to the Foldit's new aflatoxin project for the next several weeks or so, after which scientists will synthesize genes based on the most impressive results to be used in future studies.
