Electrical engineers have proposed a new scheme that can overcome a critical limitation of high-resolution electron microscopes: they cannot be used to image living cells because the electrons destroy the samples. The researchers suggest using a quantum mechanical measurement technique that allows electrons to sense objects remotely without ever hitting the imaged objects, thus avoiding damage.
