It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

"Every single cell can have a different chromosome structure," Cheng, a Curators' Distinguished Professor of Electrical Engineering and Computer Science, said. "Our tool helps scientists study those ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

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 ...

Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell ...

Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions. For example, ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...
