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 ...

Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...

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 ...

Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to ...

Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

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 ...

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 ...

Immune cells must strike a delicate balance between persistence and performance, especially in the hostile environments created by cancer and chronic infection. New research has uncovered genetic ...

“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 ...

The future of federally funded research at Harvard Medical School — supported by taxpayers and done in service to humanity — remains uncertain. Learn more. One of the most enduring goals in ...
