As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

In a major leap forward for genetic and biomedical research, scientists have developed a powerful new artificial intelligence tool that can predict the 3D shape of chromosomes inside individual cells ...

SEM images of male and female human aortic valve tissue samples from two healthy patients and two patients diagnosed with AVS. Scale bars, 5 micrometers. A study led by bioengineers at the University ...

Across ant evolution, colonies have repeatedly split into two distinct social worlds: those ruled by a single queen and those shared among many. This difference is now linked to a supergene 1 — a ...

The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...

In this episode of Tiny Show and Tell Us, we cover the science of rainbows and why double rainbows are always mirror images. Then we talk about mysterious, yet super common, chromosomes called ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females. A study led by bioengineers at the University of ...
