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.

A feature of pancreatic cancer cells' surroundings determines whether they grow fast or become resistant to chemotherapy, a ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

"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 ...

However, RS3's molecular structure had been unknown. To solve the mammalian RS3 structure, Drs. Nicastro, Zhang, and Zhao and their colleagues used a variety of approaches to study mouse RS3, ...

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 ...

Bitter taste receptors are not only expressed in oral cavity cells but also in the gastrointestinal lining. To understand the diverse functions of these receptors, understanding the structure is ...

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build ...
