Experimental embryos and the US monkeypox emergency


In the search for novel forms of the elixir of life, an Israel-based biotech company says it plans to create embryonic versions of humans to harvest tissues for use in medical devices. implantation treatments.

Renewal Bio is pursuing recent advances in stem cell technology and artificial uterus, as 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 can form lifelike mouse embryos and keep them growing in a mechanical uterus for a few days until they grow. develop a beating heart, bleeding, and craniofacial folds.

This is the first time such an advanced embryo has been mimicked without a sperm, egg or even a uterus. Now, Hanna has set his sights on extending the technology to humans – he’s been experimenting with human cells and hopes to eventually create artificial models of human embryos. “We consider embryos the best 3D bioprinter,” he said.

Automated techniques can make AI development easier

Machine learning researchers have to make many decisions when designing new models, which means that complex models will ultimately be designed by human intuition, rather than in a systematic way. A growing field known as automated machine learning, or autoML, aims to remove that guesswork, allowing algorithms to take over decision making, which can both simplify the process. while making machine learning more accessible.

Big Tech is paying attention. Companies like Amazon and Google already offer low-code machine learning tools that leverage autoML techniques, and computer scientists are excited by the concept of being able to specify a simple problem, before asking for it. the computer finds it. But researchers still have a lot of work to do before autoML can be deployed more widely. Read full story.
