For centuries, biological imaging has relied on dyes and fluorescent labels to visualize cellular structures -- a practice that not only alters samples but can delay critical medical decisions.

Microscopes have revolutionized the practice of science, especially in the fields of biology and medicine. Just a few hundred years ago, gaining the ability to study what was previously unobservable ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

To ensure our bodies function correctly, the cells that compose them must operate properly. Imagine a cell as a bustling city where tiny parts called organelles move, reorganize, and respond to ...

In a breakthrough for research fields as diverse as diabetes, atherosclerosis and biofuels, the mass, concentration, volume, and surface area of individual lipid droplets have been measured in live, ...

ELECTRON microscope investigations of ‘fibrinoid’ in Aschoff nodules from biopsy specimens of the left atrial appendage in mitral stenosis have shown that collagen fibrils are intimately related to ...

Sensing: point-of-care sensors, mobile-phone enabled sensors, field-based sensing and measurement systems with applications in mobile health and telemedicine, environmental monitoring (for example, ...

Left, a tissue sample dyed by traditional methods. Centre, a computed stain created from infrared–optical hybrid imaging. Right, tissue types identified with infrared data; the pink in this image ...
