The ability of cells to migrate is fundamental in many physiological processes, including immune responses, embryonic development, angiogenesis, regeneration, and wound healing. In addition, cancer ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...

Transmission electron microscopy (TEM) has long been the gold standard for detecting asbestos fibers in air samples drawn at construction sites. But researchers have found that a cheaper, less ...

A laser (purple) is powerfully amplified by highly polished mirrors and focused on the electron beam (blue) to shift its phase and increase the cryo-EM microscope’s contrast, allowing biologists to ...

You know when you are at the eye doctor getting an updated prescription, and suddenly the world snaps into sharper focus? Physicists at the University of California (UC), Berkeley, have now done ...

For decades, a laboratory procedure known as transmission electron microscopy (TEM) has been used to test for asbestos in samples taken at construction sites. In 1989, the U.S. Environmental ...
