What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the ...

Researchers have developed a new X-ray nanotomography microscope. Using their new system, they can reveal the structures on the smallest components of mammalian cells in three dimensions. For the ...

The N.C. Brown Center for Ultrastructure Studies in Baker Laboratory provides instruction and assistance in light microscopy methods, scanning electron microscopy, transmission electron microscopy, ...

Ultrastructure expansion microscopy of murine male germ cells reveals the fine molecular structures of centrioles (shown in the enlarged image). DNA is stained in blue, and the chromosome axis in red.

Wood ultrastructure of the Tulip Tree (Liriodendron tulipifera), Amborella (Amborella trichopoda) and Joint fir (Gnetum edule) at x1000 and x50,000 magnifications under cryo-SEM. Wood cells and cell ...

Inside a cell, tentacled vesicles shuttle cargo for sorting. Neighboring neurons cling to one another through a web-like interface. DNA rearranges in the nucleus as stem cells differentiate into ...
