Scientists have achieved a genetic feat once thought impossible: removing an entire extra human chromosome using gene-editing ...

Chromosomes are tiny, filamentous structures in the cell nuclei of living beings. They contain genes with genetic information, for example, related to the development or control of diseases. Every ...

New study in Science suggests genetics might account for 50-55% of human lifespan, a significant shift from previous beliefs.

SciShow is supported by Brilliant.org. Tiny versions of chromosomes show up in things like birds, reptiles, and amphibians.

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

Our genome isn’t as peaceful as it looks—some DNA elements are constantly trying to disrupt it. Scientists studying fruit ...

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed – so the other is randomly inactivated. Some cells use only a ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
