In a search for new forms of longevity medicine, an Israel-based biotech company says it intends to create embryonic-stage versions of people to harvest tissue for use in transplant treatments.
The company, Renewal Bio, looks to recent advances in stem cell technology and artificial wombs, demonstrated by Jacob Hanna, a biologist at the Weizmann Institute of Science in Rehovot. Earlier this week, Hanna demonstrated that from mouse stem cells, his lab could make very realistic-looking mouse embryos and keep them growing in a mechanical womb for several days until they developed beating hearts, flowing blood and folds. cranial.
It is the first time such an advanced embryo has been mimicked without sperm, eggs or even a uterus. Now Hanna has set her sights on spreading the technology to humans; she is already experimenting with human cells and hopes to eventually produce artificial models of human embryos. “We consider the embryo to be the best 3D bioprinter,” she says.

Automated techniques could make AI development easier
Machine learning researchers have many decisions to make when designing new models, which means that complex models end up being designed by human intuition, rather than systematically. A growing field called automatic machine learning, or autoML, aims to remove that guesswork, letting algorithms take over the decision-making, which could 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 by the idea of being able to simply specify a problem, before tasking the computer to solve it. But the researchers have a lot of work to do before AutoML can be implemented more widely. Read the full story.
