It is well known that inside nearly every living cell on this planet, there are instructions powering the dynamics of everything in the cell, known as deoxyribonucleic acid (DNA). Enoch Yeung, Associate Professor of Mechanical Engineering at UC, Santa Barbara, explains how DNA is the genetic code that tells cells where to live, how to live, and how to adapt when things get tough. Editing DNA has unlocked new potential in biology, enabled new therapeutics, diagnostics, and modes of treating diseases. Since DNA is double-stranded, it literally maintains a backup copy of itself to proof-read and facilitate stability of code. The double-stranded nature of DNA also means it can sometimes encode two messages in a given length! In short, DNA is amazing. Series: "GRIT Talks" [Science] [Show ID: 41040]

Almost every child born in the United States undergoes state-mandated newborn screening within the first 48 hours of life. The blood collected from a "heel stick" helps test for 80 different serious but treatable genetic disorders. These disorders can be either genetic (passed down in families) or …
UC Santa Cruz scientists, along with a consortium of researchers, have released a draft of the first human pangenome—a new, usable reference for genomics that combines the genetic material of 47 individuals from different ancestral backgrounds to allow for a deeper, more accurate understanding of w…
Elsy Buitrago-Delgado, Ph.D., shares how spatial analysis of RNA distribution during early mouse embryogenesis suggests that the first cell fate choice is made at the 4-cell stage. She also discusses how notch signaling regulates cell fate choices during early human development. Series: "Stem Cell …
Are you curious about the future of medical treatments and how they might impact your health? Malcolm Moos, Jr., M.D., Ph.D., shares how cellular therapies are revolutionizing medical treatments.

We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research suggests…
