This is Doom running on E. coli bacteria

It's Wednesday, January 31, 2024.

MIT biotech researcher Lauren “Ren” Ramlan has run the iconic computer game Doom using gut bacteria. It’s not doing the running of the game, per se, but it is running (barely) on a display inside a cell wall made entirely of E. coli bacteria.

The researcher dosed the bacteria with fluorescent proteins to ensure they lit up like digital pixels, reaching a heady 32x48 resolution. In their paper, Ramlan says “To run Doom, all one needs is a screen and willpower,” mentioning Doom running on the digital display for a pregnancy test.

However, this is not playable. It takes 70 minutes for the bacteria to illuminate one frame of the game and another eight hours to return to its starting state. So, nearly nine hours per frame. Your Switch doesn’t sound so bad now, does it?

Samsung’s annual profits continue to decline

The company is banking on the Galaxy S24.

Samsung still hasn’t recovered from its 2022 decline in profit. In its latest earnings report, it revealed KRW 258.94 trillion ($194 billion) in annual revenue and KRW 6.57 trillion ($4.9 billion) in operating profit for the fiscal year of 2023. That’s markedly less than last year. The company says its memory business — often a money maker — showed signs of recovery but not enough to stop it from incurring KRW 2.18 trillion ($1.63 billion) in operating losses for Q4 2023. Samsung has high hopes for the Galaxy S24 series and believes the devices’ AI capabilities can help its mobile business achieve double-digit growth in 2024.
