  • When somebody publishes a bullshit paper that is eventually withdrawn, every subsequent paper citing the fraudulent work can also be withdrawn as being unreliable.

    It depends on how foundational it is, of course. If you could swap it for a dozen other papers, nobody cares. If you’re continuing the work from a retracted paper, you’re fucked (but then, you probably would have noticed some errors pretty soon anyway).

    I have a friend who basically ran a series of experiments based on a paper that was complete bullshit. And like any good biochemist, he figured he was screwing up, or the equipment was faulty, or the substrate was more cursed than usual. Lucky for him, after weeks of smashing into a brick wall of failure, he started asking other people, who also kept failing and then they figured it out.







  • Terms like “sense” and “tell” are a bit misleading. It’s very much a chemical/mechanical interaction that’s automatic. Rather like soap bubbles “sensing” when they’ve reached the surface of the water.

    Plants contain a protein called phototropin, which is activated by light. When it’s activated, it changes the shape and alignment of the “skeleton” of the cell, making it more cube-shaped as opposed to long and skinny.

    That means the light side of a plant gets shorter, while the dark side remains long. The dark side also grows slightly faster, on a count of having more cells there (you can fit more skinny cells side-by-side than wide cells), and so the plant angles and grows toward the light.

    And yes. The colour matters. Phototropin reacts best to blue light, and leaves absorb mostly red and blue light (which is why they’re green). It basically ignores the green light filtered through leaves.









  • Also, live-service games endeavour to stay relevant forever.

    For, say, God of War, you’ll eventually be done with it. You’ve played all the things, you put the box on the shelve and move on to another game. But for these forever-games, you can play them forever.

    And that means that if you want to launch a game in that market, you can’t rely on getting players who just put down God of War and want something roughly similar. You need to not only be better than Fortnite, but you need to be sufficiently better than people will abandon years of investement into Fortnite to go play your game.

    The barrier to entry is HUGE, and it’s made much worse by the idea that the new game might dissapear, meaning you wasted months (or, occasionally, days, lol).
