On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and ...

Research has demonstrated that actin waves propagate via actin polymerization on the substrate-attached cell membrane at the wave’s front and disassembly at the back of the wave. 4 Proteins named Arp2 ...

In a study published in Nature Communication recently, a team led by Prof. BI Guoqiang from the University of Science and Technology of China (USTC) and Shenzhen Institute of Advanced Technology, ...

"Seeing invisible worlds, far smaller than the wavelengths of light, is absolutely critical to understanding the matter we are engineering at the nanoscale, not just in 2D but in 3D as well," said ...

Coronary artery disease is the leading cause of death in the United States, thus the intense interest in a screening test that would allow early identification of coronary artery disease in its ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

A new way of imaging frozen biological samples using electron microscopy is providing new glimpses into the nanoscopic world of cells. Images reveal bent in-vitro tubulin microtubules next to and in a ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

What is Electron Energy Loss Spectroscopy? Electron energy loss spectroscopy (EELS) is a powerful analytical technique used to study the chemical composition, electronic structure, and local bonding ...
