Researchers on Thursday reported the latest in a surprising string of experiments in the quest to save human lives with organs from genetically modified pigs.
Similar experiments have made headlines in recent months as research into animal-to-human transplants heats up.Twice this fall, surgeons at New York University temporarily attached a pig’s kidney to blood vessels outside the body of a deceased recipient to watch them work. And earlier this month, surgeons at the University of Maryland Medical Center gave a dying man aBut scientists still needed to learn more about how to test such transplants without risking a patient’s life.
But Locke said the kidney experiment could have more far-reaching impact — because it shows that a brain-dead body can be a much-needed human model to test potential new medical treatments. The need for another source of organs is huge: While more than 41,000 transplants were performed in the U.S. last year, a record, more than 100,000 people remain on the national waiting list. Thousands die every year before getting an organ and thousands more never even get added to the list, considered too much of a long shot.
A heart transplant surgeon, Kaczorowski has done experiments testing pig organs in non-human primates that helped pave the way but “there are only things we can learn by transplanting them into humans.”

Clinical-Grade Pig Kidney Transplanted Into Human Patient in Scientific FirstFor only the second time ever – and the first involving a clinical-grade organ – a genetically modified pig kidney has successfully been transplanted into a brain-dead human body, in a milestone example of xenotransplantation. wow and alotbetterthandoom but repair and preservetheorigianl why 😭 Hi, I am a structural engineer from Iran who have many ideas. I have summarized some of my ideas on my twitter(I suggest look at the idea of generating electricity by gravity). I want to work with companies and investors. Do you want to cooperate?

Why Computers Don’t Need to Match Human IntelligenceWith continuing advances in machine learning, it makes less and less sense to compare AI to the human mind. this is excellent and is the central thesis to my website. great article There's no need to be an individual with computers. The internet is a neural network in itself. The future won't be like the movies. We are creating the hive mind. We are part of it. Computers, ai, biology is all part of the same thing. This is our future. To be all and one.
