Experimental embryos and the American monkeypox emergency

In the search for new longevity drugs, an Israel-based biotech company has said it intends to create embryonic-stage humans so it can harvest tissue for transplant therapy.

The company, Renewal Bio, is pursuing the latest advances in stem cell technology and artificial wombs, as evidenced by biologist Jacob Hanna of the Weizmann Institute of Science in Rehovot. Earlier this week, Hannah showed that starting with mouse stem cells, his lab can form highly realistic mouse embryos and grow them in mechanical wombs for days until they develop beating hearts, flowing blood and cranial folds.

This is the first time such an advanced embryo has been simulated without sperm, eggs or even a uterus. Now Hanna has his sights set on bringing the technology to humans—he is already experimenting with human cells and hopes to eventually produce artificial models of human embryos. “We think embryos are the best 3D bioprinter,” he said.

Automation technology can make it easier to develop artificial intelligence

Machine learning researchers have to make many decisions when designing new models, which means that complex models are ultimately designed by human intuition rather than systematically. A growing field called automated machine learning, or autoML, aims to remove this guesswork, allowing algorithms to take over decision-making, which can 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 leverage autoML techniques, and computer scientists are excited about the concept of being able to simply specify a problem before a computer solves it. But researchers still have a lot of work to do before autoML can be deployed more widely. Read the full article.
