Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic ...

Researchers at Dresden University of Technology reveal that early zebrafish embryos divide without a closed actin ring.

Life’s fundamental structure is the cell, and so the main things that a cell does — processing biomolecules, growing, replicating its genetic material and producing a new body — are considered ...

Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...

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 ...

Understanding the human cell is vital to progress in the life sciences and to human health. Cells are the smallest, most basic unit of life responsible for all of life’s processes. A typical human ...

Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental time. In humans, pregnancy lasts around nine months. In mice, only 20 days, and ...
