Chinese doctors treated an end-stage type 2 diabetic patient by implanting islet tissue derived in vitro from his own endoderm stem cells. The patient has been insulin-independent for 33 months.
  • Percutaneous: means "through the skin"

    Transhepatic: means "across the liver"

    Portal vein: a major vein that carries blood from the intestines to the liver

    Transplantation: surgical procedure involving the removal of an organ or tissue from one person (donor) and placing it in another person (recipient)

    Just use LLM these days!

  • IBM releases first-ever 1,000-qubit quantum chip
  • These qubits oscillate at microwave frequencies where the quantum information is stored. This means they need to be kept at a temperature where the microwave frequencies are completely devoid of any thermal noise. For microwave frequencies, this temperature is just a few millikelvins above absolute zero. Unfortunately, the temperature is required due to the fundamental nature of thermal noise due to temperature. Making the qubits out of room temperature superconductor would not solve the problem of the need to cool them down - unless they can be operated at higher frequency. There are quantum computers made using light/optical photons which do operate at room temperature because optical photons are at much higher frequency which has no thermal noise even at room temperature.

    So, in conclusion, everytime you hear about superconducting qubit, they are always in a giant dilution refrigerator which gets bigger for more qubits as more connections from room temperature to qubits are needed.

  • IBM releases first-ever 1,000-qubit quantum chip
  • For now they are only being used for research purposes. For example, simulating Quantum effects in many atom physics and implementing error correction for future quantum computers. Any real applications still need some time but the pace of development is really quite something.

    If this LK-99 stuff is real, it would allow (potentially) for lossless electric transmission lines at great distances; mainstreaming of efficient nuclear fusion; anti-gravity cars or plane...
  • We are still not sure. The paper was published under very suspicious circumstances. However, since the recipe is given in the paper, many groups around the world are running tests. We still need to wait a few more days for more conclusive results. With the results until now, it seems that the material is at least very strongly diamagnetic but I haven't seen any conclusive proof of zero resistivity confirmed by another lab.

  • First room temperature and pressure superconductor discovered
  • Yeah, in olden times sure. You can say a big paper like EPR paradox one, was written as only three people. These days, a lot of people would jump on a big paper since citations is the currency of research now.

  • First room temperature and pressure superconductor discovered
  • To be honest, this seems very sus to me. A big paper with only three authors?! I went down the rabbit hole of trying to find the lab from which it has been published. It's almost there is no online presence. In another paper they put out along with it, they say that they show Meissner effect (levitating effect of a superconductor) and that a video is attached. I looked for the video but I wasn't able to find it. :/
