A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism.

Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes inside a living organism are imaged at high resolution.

By engineering cells to express a modified RNA called "Spinach," researchers have imaged small-molecule metabolites in living cells and observed how their levels change over time.

The great artist and inventor Leonardo da Vinci once said that "simplicity is the ultimate sophistication."

Researchers at the University of California, San Diego School of Medicine have created a new generation of fast-acting fluorescent dyes that optically highlight electrical activity in neuronal membranes.
