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 ...

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 ...

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...

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 ...

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

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

What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...

When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In ...

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 ...

“We have trained healthy cells to share their spare batteries with weaker ones,” Akhilesh Gaharwar, PhD, a researcher on the study, explains in a press release. “By increasing the number of ...

This atlas revealed specific TFs that distinguish TEX term cells from T RM ones. Although some regulators were shared, two previously unstudied TFs, ZSCAN20 and JDP2, emerged as selective drivers of ...
