  1. Re:How did the ions get there? on Astronomers Have Spotted the Universe's First Molecule (sciencemag.org) · · Score: 1

    Hydrogen (H+) is just a proton. Helium (He+) is two protons. (if you want to get into isotopes we can involve neutrons but I digress). In short these are about as simple as you can get while being more than elementary particles.

    To put it succinctly, it isn't the protein/lipid structure that is doing it, which would be more stable, but the ions and chemokines bound to the right spots on the cell surfaces. That's why your brain function can be affected by drugs rather than just the way the neurons grow.

  3. Re:Chemical machine on 'Partly Alive': Scientists Revive Cells in Brains From Dead Pigs (nytimes.com) · · Score: 1

    So... if you're very recently brain dead some of cells may still work but enough of them are gone that the connections between them - where your memories are stored - have degraded and are also gone. You could probably flip some bits on a hard drive platter by hand, but if it is rusting in the open air it'll never spin up again. If we got some sci-fi nano tech and could repair the individual cells somehow, your neuron net is going to end up reformatted because those connections are fairly tenuous.

    Is this surprising to non-biologists? Cells are like machines made of chemicals. You can run electrical current through a dead frog to make its leg jump... until it finishes breaking down. Doesn't mean you could 'repair' the frog back to life.

  5. Insect population collapse on Microplastics Are Blowing In the Wind (scientificamerican.com) · · Score: 4, Interesting

    I wonder if this sort of thing could be part of the collapse of insect populations in otherwise pristine environments. Vertebrates could probably clear most of this via mucus but arthropods aspirate differently.

  6. Re:Carelessness neutrophils on Immune Cells May Play a Role In Causing Cavities (newatlas.com) · · Score: 1

    Overzealous immune response is the cause of pathology in many instances: host-graft disease, auto-immune disease, 1918 flu, hantavirus, allergy, etc. As with something like chemo, it is just that what is bad for you is hopefully worse for the pathogen and your body packs things up afterward.

    Dentistry pushes what is necessary to accommodate a diet based on grain. Civilization's diet is based on grain because it is the cheapest and easiest way to avoid starving, you can grow a lot of it, and agrarian societies eventually push out hunter-gatherers. Dogs compared to wolves are also more able to accommodate grain in their diet. Inflammation related to eating grain is kind of like lactose intolerance... the genes for being able to eat grain and retain lactase are relatively new and haven't made full penetration into humanity. Tolerance of a high fat diet is also restricted to specific genotypes that are more prevalent in some places than others. It is good that you found a diet suitable to you, but it is an error to imagine that it is universally applicable.

  8. Does this mean we'll be able to set the relative volumes without having to guess as to which application is being considered in the "foreground"? Trying to adjust the turn by turn volume while you have music playing is extremely annoying.

    Obviously the bioluminescent organisms that make their eyes glow blue give off methane, which the dead dragon's ignition organ (perhaps an electric spark e.g. an eel) can still ignite, meanwhile ... ramble ramble reverse the tachyon flow...

  14. Re:Steam vapor? Really? on The ISS Is a Cesspool of Bacteria and Fungi, Study Finds (gizmodo.com) · · Score: 1

    The other standard methods of decontaminating an arbitrary surface are bleach, or vaporized peroxide, so if the steam works it might actually be less harsh. The trouble with decontaminating stuff in space is that you're already selecting for extra hardy organisms. Thinking about hardy organisms living in NEO, I wonder if water bears would eat the biofilm on the ISS...

    Yes, there are pros and cons to all the various form factors... the fold around 2in1s save you from having to find a place to set the keyboard down when you aren't using it but then you're mushing keys on the back the whole time. My point was mostly that it is a tablet form factor that can use real PC peripherals. Unless the parent post meant 'real tablet' in terms of other factors like battery life, but there has to be a compromise somewhere if you're running multicore and wirelessly connecting to a bunch of stuff because there are only a few USB C ports to choose from. To my kids, 'daddy's laptop' is just like 'mommy's ipad' except it can do more things.

  16. Re:No, just shrinking market on The End of the Desktop? (computerworld.com) · · Score: 1

    A Surface or equivalent clone with the keyboard off is a tablet that has full PC functionality. I've got an HP clone and it is great having that vs a 'giant phone' style tablet, you can get real free/open source apps for the kids to play with vs freemium adware from a walled garden.

    So maybe this use case could be a non-scam use for blockchain - the most useful thing the journals do in the internet era is sort of authentication; they curate papers from reputable sources and sort of help facilitate the peer review. This gets hard to do when you decentralize, so maybe a blockchain can be utilized to manage the peer credentialing that elevates the impact of a paper.

    Fungi are bigger and more like us than viruses and bacteria are. So instead of being dependent on specific protein binding sites like a virus is, they can mechanically invade tissue like a parasitic worm could. They may have plant-like lifecycles but they have to find exogenous energy sources as animals do, so that's why so many consume detritus or are parasites.
