Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

A recent study by the University of Bonn and University Hospital Bonn and the University of Freiburg shows that the ...

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 ...

Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.

Your brain begins as a single cell. When all is said and done, it will house an incredibly complex and powerful network of some 170 billion cells. How does it organize itself along the way? Cold ...

Let’s start with a quick biology refresher: Mitochondria are the powerhouse of the cell. They convert the food we eat into ...

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Physically magnifying objects using a key moisture-absorbing ingredient in diapers has opened an unprecedented view of the microbial world. When you slip a slide under a microscope, a system of glass ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

HeLa cells are the most famous human cells in science. Discover how cervical cancer, HPV proteins, and bioethics shaped one ...
