In search of new forms of longevity medicine, an Israel-based biotech company says it intends to create embryonic versions of humans to harvest tissue for use in transplant treatments.

Renewal Bio deals with the latest advances in stem cell technology and artificial wombs, as demonstrated by Jacob Hanna, a biologist at the Weizmann Institute of Science in Rehovot. Earlier this week, Hanna showed that by starting with mouse stem cells, his lab can create highly realistic mouse embryos and keep them growing in a mechanical womb for days until they develop a heartbeat, flowing blood and cranial folds.

This is the first time such an advanced embryo has been simulated without sperm, eggs or even a uterus. Hanna now aims to extend this technology to humans — he is already experimenting with human cells and hopes to eventually create artificial models of human embryos. “We think of the embryo as the ultimate 3D bioprinter,” he says.

Automated techniques can facilitate AI development

Machine learning researchers have to make many decisions when developing new models, meaning that complex models end up being developed by human intuition rather than systematically. A growing field called automated machine learning, or autoML, aims to remove that guesswork by letting algorithms take over the decision-making, which could both simplify the process and make machine learning more accessible.

Big Tech is paying attention. Companies like Amazon and Google already offer low-code machine learning tools that take advantage of autoML techniques, and computer scientists are excited about the ability to simply specify a problem before letting a computer figure it out. But researchers still have a lot of work to do before autoML becomes more widely available. Read the story in its entirety.
