    If you have a weird phoneme / meaning mapping brain like mine, I would note that he is not the doctor who is known for the "replication crisis". Even though Ioannis means John in Greek. Took me a second to tease that out. https://en.wikipedia.org/wiki/John_Ioannidis https://en.wikipedia.org/wiki/John_Ioannidis

  To understand the significance of artificial skin, first consider all sorts of bad things that happen after deep burn. The dead tissue in a burn wound can release toxins and provide nutrients for bacteria to grow, which in turn can spread toxins and infection throughout the body, eventually causing multiple organ failure and death. Early treatment of deep burns focuses on interrupting this cascade reaction by removing the dead tissue. The now-cleaned wound needs to be covered. Skin from many species, including chicken, rat, pigeon, cat, dog, frog, cow, and pig, has been tested, and pig skin was found to be the best. As the wound's condition improves, healthy skin from the same patient is grafted or seeded onto the wound to assist healing. Although pig skin is still widely used, the biggest problem is that it is from a different species and therefore can be immune rejected. Gene-edited pig skin helps, but it may still require immunosuppressive therapy, which is not helpful when the patient is at high risk of infection. Artificial skin has the potential for better temporary wound cover, and ideally, it can promote healing without skin grafting or using less skin for grafting.

      The real slop is dragging AI into every conversation.

        The whole frontpage has been infested with LLM BS for a very long time with absurd claims about it being of landing-on-the-moon levels of breakthrough yet here you are claiming the ones pointing out this fact are the problem.
        • squigz 1y ago
          Pointing out this fact at every possible opportunity, even when grossly inappropriate, is not helpful.

            [Someone from the moderation team care to explain the reasoning behind flagging this comment?] Characterizing as grossly inappropriate the statement of the reality of the monopoly on research funding on useless -as of now- AI and not even addressing the initial point is very telling of your dedication to VC brainwashing.

          So why do you want to drag debates about that into even closer to 100% of all posts?

  Someone close to me needed an artificial skin product (I think it was a subsequent generation product, not this one) to close a stubbornly unhealed wound on their lower leg. It worked like a charm after previous treatments had failed. Big QoL improvement.

    > I think it was a subsequent generation product Maybe it was "spray on skin", an alternative approach? https://en.wikipedia.org/wiki/Spray-on_skin https://en.wikipedia.org/wiki/Spray-on_skin https://en.wikipedia.org/wiki/Avita_Medical#ReCell,_spray-on_skin https://en.wikipedia.org/wiki/Avita_Medical#ReCell,_spray-on...

      No, it was applied in patches.
