Metabolism, far from being just a housekeeping function, underlies all changes in cell size and function ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

Researchers have developed a way to 3D print custom micrometer-sized structures directly into the interior of living cells.
