      Hey everyone,

      As a few of you may know, there was a paper released a few days ago claiming that an Room-Temperature Ambient-Pressure Superconductor (RTAPS) was created. You can see the original paper here: https://arxiv.org/abs/2307.12008

      To bring things into perspective if this holds true we would likely dispense with energy and transportation concerns. It would be akin to the discovery of fire, penicillin or the transistor. A groundbreaking change. See here for a more detailed, bullish list of things it can help with: https://nitter.net/Andercot/status/1685088625187495936

      There are many communities that are discussing this. The best summary I was able to find is here: https://forums.spacebattles.com/threads/claims-of-room-temperature-and-ambient-pressure-superconductor.1106083/page-17

      There is still a very much active debate there (and elsewhere online) of people on the viability of the original people. Many are pessimistic that the evidence is scant and that the original publication does not hold its water. An interesting summary of the sentiment of a part of the community can be found through the (faux) betting market of Manifold here: https://manifold.markets/QuantumObserver/will-the-lk99-room-temp-ambient-pre

      On the link above they are also diligently tracking any replication attempts. Currently we are at the stage were theoretical simulations have validated the possibility of the purported materials to be superconductors (https://arxiv.org/abs/2307.16892).

      Finally, a nice replication attempt that tried to make the creation process better and demonstrated some of the effects required to prove superconductivity (scroll up): https://twitter.com/iris_IGB/status/1685804254718459904

      This is very exciting, because even if some properties are valid, it gives a mjor boost to the whole field.

    2. Folks in the biotech industry, what do you do and what is it like?

      I've been doing a postdoc in molecular biology in academia for a little while now, and getting ready to take next step. I'm looking into industry careers, but it's difficult to know what they...

      I've been doing a postdoc in molecular biology in academia for a little while now, and getting ready to take next step. I'm looking into industry careers, but it's difficult to know what they entail since we don't often get exposed to them.

      If you or someone you know works in biotech, I'd love to hear about it.

      How did you get into it? What do you enjoy or not enjoy? Where do you see the industry heading? What are some of the positions like?

    3. Can someone please explain like I'm five how or whether the energy needs for technical civilization in the future can possibly be met?

      So from earliest childhood, I have experienced that from time to time the electrical grid becomes unavailable for use and it can take days or even weeks to restore service. I'm having trouble...

      So from earliest childhood, I have experienced that from time to time the electrical grid becomes unavailable for use and it can take days or even weeks to restore service. I'm having trouble comprehending the scope, scale and plausibility of what changes would need to be made to increase the electrification of everything in the way that is being pushed by policy advisors.

      Everyone is pushing electric cars. I think it's a great idea, but I have questions about how the grid can support it.

      People tell me that the next big advancement in the workplace is going to be the incorporation of artificial intelligence. Doesn't AI require servers on a massive scale? How plausible is it for AI to reach all corners of society and economy on our existing grid or reasonable expectations for plausible improvement of the grid?

      The banks seem to be lobbying for the substitution of electronic accounts for cash. Again, electric power is not always available. Also some people who need to use money don't have homes and can't reliably charge electronics. If I remember correctly the payment system went down in Canada a while ago and people without cash were out of luck.

      What insight can you share with me?
