Chimpanzees and bonobos may be very close to us humans on the tree of life, but one of our differences is the way we store fat. That difference comes down to types of fat cells and our DNA. Hosted by: Hank Green

Our understanding of both clogged arteries and the building blocks of DNA are thanks to the groundbreaking work of Dr. Marie M. Daly, the first Black woman in the U.S. to receive a Ph. D. in chemistry.

As many as 50 million people worldwide may live with Alzheimer's and similar forms of dementia, and while we still don't understand a lot about it, scientists may be one step closer to an effective treatment.

You know all about how DNA bases can code for an organism's traits, but did you know there's more influencing phenotype than just the bases? Explore epigenetics with the Amoeba Sisters by learning about a few types of epigenetic marks...

In this video Paul Andersen answers this question about chromosomes. He explains how the base pairs of DNA form genes which are organized into the chromosomes of the overall genome.

In this video Paul Andersen explains how scientific theories are created and modified over time. He starts by discussing the theory of natural selection as a model for the creation and modification of theories. He gives examples of...

New research claims it has successfully reversed memory loss in an animal model of Alzheimer's.

We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to...
