Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both ...
In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...
While fluorescence imaging (in which external light is used to excite a specimen that then emits light in response) is essential in cell biology, it has a number of significant drawbacks, including autofluorescence, phototoxicity ...
The editors at the journal Frontiers in Cell and Developmental Biology have retracted a paper after it was pointed out to them by readers that supporting images had been generated improperly by an AI image generator. In their ...
Researchers in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University have uncovered something new in one of the most studied organisms on Earth, and their discoveries could impact ...

Fluorescence imaging can be conducted with long Stokes shift dyes that minimize crosstalk between the excitation source and fluorescent emission to improve the signal-to-background ratio. Regardless, researchers still form ...
Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image—almost like a video camera—of the faint electric fields generated by the rhythmic ...
