Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...

Details of the process in which plants transfer gases through the pores on their leaves called stomata remain hard to study. The anatomy of stomata can be seen through optical microscopy, but ...

Aim To map, summarise and analyse the methodologies of corneal nerve fibre imaging in studies using in vivo confocal microscopy (IVCM) in diabetes and assess the potential for standardising methods ...

The brain is the most energy-demanding organ in the body, in part due to its complexity. Its components are varied and intricate: comprising different cell types, including neurons designed to ...

Scientists have built a microscope capable of visualizing optical responses at the scale of individual atoms, redefining the limits of optical imaging. Scientists have created a groundbreaking ...

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 ...

Both images show individual red blood cells. The one on the right, produced by STED, more clearly shows the Piezo1 proteins (in green), which are a mechanical calcium channel and play a crucial role ...
