Pig kidney sets record in human patient. A U.S. man has lived a record nine months with a gene-edited pig kidney while awaiting a human transplant, a milestone in the effort to ease the organ shortage.

According to the BBC, the gene-edited organ functioned in the patient's body for 271 days, the longest reported duration for a pig kidney in a human. The case marks progress for xenotransplantation, the use of animal organs in people, which researchers are pursuing as one response to the shortage of human donor organs. The man received the kidney as a bridge while remaining on the list for a human transplant.

Ars Technica reports the deal gives the chipmaker control of a central piece of AI infrastructure, the hub where developers share and distribute machine-learning models. The outlet notes Nvidia's pledge to keep the platform open comes even as the acquisition places that widely used resource under the control of the chip giant, a tension likely to draw attention across the AI development community.

Psilocybin blocks chemo side effect in mice. The magic-mushroom compound prevented chemotherapy-induced peripheral neuropathy, a painful nerve condition, in mice. That points to a way to spare cancer patients the treatment-disrupting complication.

The findings, reported in Nature, address a complication that is common among people undergoing chemotherapy and can be painful enough to disrupt cancer treatment. Because the results come from experiments in mice, the compound's protective effect would still need to be demonstrated in humans before it could change how the side effect is managed in cancer care.
