Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

In a study that may guide drug design, researchers find organelles encounter varying levels of resistance, depending on their size and speed, as they move through a cell's cytoplasm. Under a ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is densely packed with biomolecules like proteins and nucleic acids. How is ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

The inside of a cell is packed with stuff; from big organelles to small molecules, the cytoplasm is the suspension which contains all those components. Researchers at MIT wanted to know more about how ...

UC Davis researchers tracked the movement of fluorescent particles inside the cells of microscopic worms, providing novel insights into cellular crowding in a multicellular animal. They found that the ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...
