Corruption is sending shock waves through China’s chipmaking industry

China’s chipmaking industry descended into chaos last week, with at least four top executives associated with a state-owned semiconductor fund arrested on corruption charges. It’s an explosive turn of events that could force the country to fundamentally rethink how it invests in chip development, according to analysts and experts. 

On July 30, China’s top anticorruption institution announced that Ding Wenwu, the chief executive of the China Integrated Circuit Industry Investment Fund, nicknamed the “Big Fund,” had been arrested for “suspected serious violations of the law.” Ding is not the only person in trouble. Two weeks ago, Lu Jun, a former …

This startup wants to copy you into an embryo for organ harvesting

In a search for novel forms of longevity medicine, a biotech company based in Israel says it intends to create embryo-stage versions of people in order to harvest tissues 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 …

Automated techniques could make it easier to develop AI

Machine-learning researchers make many decisions when designing new models. They decide how many layers to include in neural networks and what weights to give inputs at each node. The result of all this human decision-making is that complex models end up being “designed by intuition” rather than systematically, says Frank Hutter, head of the machine-learning lab at the University of Freiburg in Germany.

A growing field called automated machine learning, or autoML, aims to eliminate the guesswork. The idea is to have algorithms take over the decisions that researchers currently have to make when designing models. Ultimately, these techniques …

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 highly realistic-looking mouse embryos and keep them growing in a mechanical womb for several days until they developed beating hearts, flowing blood, and …

Researchers repaired cells in damaged pig organs an hour after it died

The news: A new system called OrganEx stopped the deterioration of cells in pig organs one hour after the animal’s death, a finding that suggests cells don’t die as quickly as previously understood. The technology successfully restored blood circulation and repaired damaged cells in the pigs.

Why it matters: Experts have called the research “truly remarkable,” adding that if scientists are able to …
