Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by ...

Transmission electron microscopy reveals the architecture of cells at nanometer resolution, but chemical fixation severely warps their native structure. The true ultrastructure of cells can be ...

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 ...

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, ...

Expansion microscopy image of Lacrymaria, a ciliated eukaryotic microorganism, collected from environmental samples in Tokyo. Highlighted in green is tubulin, the major protein component of ...

The aldehydes introduced in this paper and the more appropriate concentrations for their general use as fixatives are: 4 to 6.5 per cent glutaraldehyde, 4 per cent glyoxal, 12.5 per cent ...

Litobothrium aenigmaticum Caira, Jensen, Waeschenbach,& Littlewood 2014 is a cestode species that parasitizes pelagic thresher sharks in Taiwan and the Gulf of California. A previous study using light ...

Plankton are the invisible engines of life on Earth, producing much of the planet's oxygen and forming the foundation of the oceanic food chain. They are also incredibly diverse, with tens of ...

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.
