Researchers repaired cells in damaged pig organs an hour after it died

The news: A new system called OrganEx stopped the deterioration of cells in pig organs one hour after the animal’s death, a finding that suggests cells don’t die as quickly as previously understood. The technology successfully restored blood circulation and repaired damaged cells in the pigs.

Why it matters: Experts have called the research “truly remarkable,” adding that if scientists are able to intervene and prevent permanent cell failure, it raises serious questions over how we define a biological death. The study could pave the way to making human organs more viable for transplantation by making them last longer, and in better condition, post-removal, and could also help towards developing methods to treat strokes and heart attacks.

What’s next?: The team is planning future studies in animals, and an obvious next step is to try to study whether organs treated using OrganEx are viable for transplantation. While they’re keen to emphasize the technology is not yet ready for use in humans, they’re cautiously optimistic the system may be able to salvage organs that would otherwise have been unusable.

The big story

AI is wrestling with a replication crisis

November 2020

Back in October 2020, Nature published a damning response written by 31 scientists to a Google Health study that had appeared in the journal earlier that year. Google was describing successful trials of an AI that looked for signs of breast cancer in medical images. But according to its critics, the Google team provided so little information about its code and how it was tested that the study amounted to nothing more than a promotion of proprietary tech.

The group is among a growing number of scientists pushing back against a perceived lack of transparency in AI research, claiming that the very high-profile journal had published an advertisement for cool technology that had nothing to do with science. AI already suffers from the black-box problem: it can be impossible to say exactly how or why a machine-learning model produces the results it does—and a lack of transparency in research makes things worse.
