It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

A new discovery inside your cells may change how scientists understand disease and design future treatments. Researchers have found a previously unknown structure in mammalian cells, something they ...

"Every single cell can have a different chromosome structure," Cheng, a Curators' Distinguished Professor of Electrical Engineering and Computer Science, said. "Our tool helps scientists study those ...

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell ...

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is ...

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders. The existence of the organelle—which has been dubbed the "hemifusome"—was ...

Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure.
