This is today's edition of The Download , our weekday newsletter that provides a daily dose of what's going on in the world of technology. Supercooled kidneys have been transplanted into pigs in a “landmark achievement” When it comes to organ donation, time is everything. As soon as an organ has been removed from a donor’s body, it starts to deteriorate. Surgeons have only a matter of hours to get it into a recipient. In most cases, organs will be kept on ice during that time, at around 4 °C (39 °F). They cannot be frozen—in previous attempts, ice has formed, causing all kinds of damage. But now, scientists have come up with a device that allows organs to be cooled to -4 °C (25 °F) without forming any ice. They’ve tested it with pig organs and shown that kidneys, at least, can be preserved in the device for days then successfully transplanted. Read our story about their breakthrough, and why it raises hopes for longer-term storage of donated human organs. —Jessica Hamzelou If you want to read more about this story and its implications for organ preservation and transplantation, sign up to receive The Checkup, our weekly biotech newsletter, later today.

One More Thing AI is changing how we study bird migration In a warming world increasingly full of human infrastructure that can be deadly to them, like glass skyscrapers and power lines, migratory birds are facing many existential threats. Scientists rely on a combination of methods to track the timing and location of their migrations, though each has shortcomings. But now, machine-learning tools are unlocking a treasure trove of acoustic data for ecologists.
