Stanford Team Develops Electromagnetic Cell Sorter That Levitates Cells by Density

Researchers at Stanford Medicine have developed a novel cell sorting device that uses electromagnetic forces to levitate and separate cells based on density. The technology enables gentle, label-free sorting of live versus dead cells and identification of cancer cell clusters without damaging samples.

A Magnetic Approach to Cell Sorting

What looks like cellular magic—cells floating upward from a liquid medium to hover at precise heights—is actually a sophisticated new sorting technology emerging from Stanford Medicine laboratories. According to recent reports in the Proceedings of the National Academy of Sciences, researchers have developed an electromagnetic device that levitates cells to separate them by type and condition without physical contact.

China Expands Rare Earth Export Controls Amid Escalating Trade Tensions With US

China has expanded export controls on rare earth minerals and related technology, according to recent reports. The move has escalated trade tensions with the United States, with officials describing it as a “global supply-chain power grab.”

Expanding Export Restrictions

China has reportedly expanded its export controls on rare earth elements, adding five more minerals to the seven already restricted since April, according to the Ministry of Commerce. The new regulations cover not only the rare earths themselves but also equipment required for mining, smelting, and recycling operations. Sources indicate the controls extend to activities that could transfer rare earth expertise abroad, including teaching, employment, and consulting services.
