flag A new study shows engineered proteins can change brightness with magnetic fields, enabling non-invasive cell imaging and control.

flag A new study published in Nature on January 21, 2026, reveals that engineered fluorescent proteins, including MagLOV, can change brightness in response to magnetic fields due to quantum effects, enabling non-invasive control and imaging of cells using magnets and radio waves. flag Researchers from the University of Oxford and the Chan Zuckerberg Biohub used directed evolution to develop these magneto-sensitive proteins, which respond to light and magnetic fields, offering potential for real-time tracking of biological processes in living tissues. flag The breakthrough, inspired by bird navigation and based on a protein from oats, could lead to new biomedical tools for disease monitoring and targeted therapies.
