What's Happening?
A study led by the University of Oxford has demonstrated the use of quantum spin resonance in engineered proteins for biological sensing in bacteria. The research, published in Nature, introduces a new class of biomolecules called magneto-sensitive fluorescent
proteins (MFPs), which interact with magnetic fields and radio waves. This marks the first practical application of quantum effects in biological systems. The engineered protein, MagLOV, exhibits optically detected magnetic resonance in living bacterial cells, enabling single-cell detection. The study is part of a broader initiative to understand animal magnetoreception and develop biomedical tools.
