Biologists are very interested in how proteins, lipids and other compounds are organized and interact in systems. Very few organizational details can be gained by using standard transmission-based ...

Cells In A New Light By combining the sensitivity of fluorescent dyes with optical systems that can detect colorful but low-intensity fluorescent light, researchers in many life sciences are able to ...

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue ...

Imagine you’re sitting at a pond, listening to the din of croaking frogs. You want to know how many frogs are in the pond, but you can’t pick out the individual croaks—only the combined sound rising ...

Processes in the human body are shaped by the interaction of various biomolecules, such as proteins and DNA. These processes take place in a range of often just a few nanometers. They can therefore no ...
