Our cells are constantly communicating, and scientists have developed an efficient way to find out what messages they are sending in protein-packed biological suitcases called exosomes. These ...

Imaging miniscule biological structures is rife with challenges. As instruments zoom in on ever-smaller parts, one problem that arises is background noise – interference coming from myriad sources ...

Imaging very small materials takes not only great skill on the part of the microscopist, but also great instruments and techniques. For a refined microscopic look at biological materials, the ...

A joint team of scientists from Russia and the United States designed a method for marking dividing stem cells with three different labels. Until now, it was only possible to use two labels ...

Uniform protein labeling in intact tissues is a challenge. An approach that allows antibodies to seep within organs could label proteins in millions of cells. Conventional protein-tagging methods, ...
