- crtasm 3y agoI'd seen the RPS piece but didn't realise there's a paper, thanks. https://www.rockpapershotgun.com/you-can-play-doom-using-gut-bacteria-but-the-framerate-is-atrocious https://www.rockpapershotgun.com/you-can-play-doom-using-gut...
- Loughla 3y agoGod bless the people who do these things But the payoff is at the end. >Doing the math, this means that it would take 599 years to run Doom on cells, according to this simulation. Regardless of where you stand in the regular debate, that's a noticeable framerate drop.
- RichardoC 3y agoWhile cool, this is just a model rather than real cells. Still an interesting thought experiment!
- blharr 3y agoYeah, at first I was a little disappointed as well when I realized it wasn't "actually" using the bacteria. But given the amount of publicity this has gotten, it is probably not too long until someone with the actual hardware is inspired to do something similar
- jl6 3y agoI like the bit where it uses the deadly food poisoning bacteria. Feels thematically on-topic.
- dekhn 3y agoE Coli is not a deadly food poisoning bacteria; it's an essential part of your gut. There are toxin-producing e coli, and also salmonella, but I don't think those get used in iGEMS competitions.
- jszymborski 3y agoRegrettably, most folks only are aware of EHEC strain of E. coli [0]. Other strains of E. coli are a workhorse in the lab and are harmless.

- dekhn 3y agoI was thinking of O-157 (https://en.wikipedia.org/wiki/Escherichia_coli_O157:H7 https://en.wikipedia.org/wiki/Escherichia_coli_O157:H7) as it was associated with ground beef contamination back in the 90s.
- jszymborski 3y agoSo I made an error in calling EHEC a strain, rather, it's an umbrella for all E. coli that produce Shiga toxin and cause human disease. The best known strain in this category is O-157:H7. Of course, I may have made some errors, my background is in biochem not microbio. https://en.wikipedia.org/wiki/Shigatoxigenic_and_verotoxigenic_Escherichia_coli?wprov=sfla1 https://en.wikipedia.org/wiki/Shigatoxigenic_and_verotoxigen...
- jl6 3y agoWhatever the most deadly one is, that’s definitely the one to use to run Doom.
- CoastalCoder 3y agoWhen I look at the document, all of the images are just grey rectangles. Maybe the document was infected with penicillium?
- jkestner 3y agoIf antibacterials will brick my screen, airgapping won’t stop the moldy bread attack.

- Decabytes 3y agoI’ve always been excited about Biocomputing. I think that it is a super cool, yet very sci-fi idea. Everyone once in awhile I see things like this and it keeps the dream alive
- thomashop 3y agohttps://en.wikipedia.org/wiki/Xenobot https://en.wikipedia.org/wiki/Xenobot Xenobots built to date have been less than 1 millimeter (0.04 inches) wide and composed of just two things: skin cells and heart muscle cells, both of which are derived from stem cells harvested from early (blastula stage) frog embryos.[7] The skin cells provide rigid support and the heart cells act as small motors, contracting and expanding in volume to propel the xenobot forward. The shape of a xenobot's body, and its distribution of skin and heart cells, are automatically designed in simulation to perform a specific task, using a process of trial and error (an evolutionary algorithm). Xenobots have been designed to walk, swim, push pellets, carry payloads, and work together in a swarm to aggregate debris scattered along the surface of their dish into neat piles. They can survive for weeks without food and heal themselves after lacerations.[2] Other kinds of motors and sensors have been incorporated into xenobots. Instead of heart muscle, xenobots can grow patches of cilia and use them as small oars for swimming.[8] However, cilia-driven xenobot locomotion is currently less controllable than cardiac-driven xenobot locomotion.[9] An RNA molecule can also be introduced to xenobots to give them molecular memory: if exposed to specific kind of light during behavior, they will glow a prespecified color when viewed under a fluorescence microscope.[9] Xenobots can also self-replicate. Xenobots can gather loose cells in their environment, forming them into new xenobots with the same capability.[10][11][12]
- nextaccountic 3y agoIs this entirely simulated, or did someone built xenobots out of live cells in a lab culture? The wikipedia page is not clear Also about self replicating, does this mean reproduction? Are they a new species?

- golem14 3y agoI'd pitch the short story (really, a fictitious book review) "Eruntics" by Stanislaw Lem. I believe it's published within the "Imaginary Magnitude" Anthology. Published in 1985.
- amenghra 3y agoThis belongs in Sigbovik.
