Biologists often use green fluorescent protein (GFP) to see what happens inside cells. GFP, which scientists first isolated in jellyfish, is a protein that changes light from one color into another.

Striking the Right Balance between Signal Strength and Long-Term Cell Health A key challenge with live-cell fluorescence imaging is the ability to visualize weak fluorescent signals over background ...

Fluorescence light microscopy has the unique ability to observe cellular processes over a scale that bridges four orders of magnitude. Yet, its application to living cells is fundamentally limited by ...

When cities transform into a colorful world of lights as darkness falls, it's often only possible to estimate their contours, which depending on the perspective can draw the attention to key details ...

A new two-photon fluorescence microscope developed at UC Davis can capture high-speed images of neural activity at cellular resolution thanks to a new adaptive sampling scheme and line illumination.
