Experimental embryos and the US monkeypox emergency


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

The company, Renewal Bio, is pursuing 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 showed that starting with mouse stem cells, his lab could form very realistic-looking mouse embryos and keep them growing in a mechanical womb for several days until they develop hearts that throbbing, flowing blood and cranial folds.

It is the first time that such an advanced embryo has been mimicked without sperm, eggs or even a uterus. Hanna has now set her sights on extending the technology to humans: she is already experimenting with human cells and hopes to eventually produce artificial models of human embryos. “We see the embryo as the ultimate bio 3D printer,” he says.

Automated techniques could facilitate the development of AI

Machine learning researchers have to make many decisions when designing new models, which means that complex models end up being designed by human intuition, rather than systematically. A growing field called automated machine learning, or autoML, aims to take that guesswork out, allowing algorithms to take over the decision-making, potentially simplifying the process and making 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 telling a computer to solve it. But researchers have a lot of work to do before autoML can be deployed more widely. Read the whole story.
