#395 Mapping Melanoma: How Spatial Biology Is Advancing Cancer Research
What if we could study melanoma not just cell by cell, but in the exact place those cells live inside the tumor?
That is the promise of spatial biology. In this episode of DNA Today, we explore how emerging genomic technologies are transforming melanoma research by allowing scientists to examine n…
TWiEVO 126: Beyond Inheritance with Roxanne Khamsi
TWiEVO 126: Beyond Inheritance with Roxanne Khamsi June 1, 2026 Science journalist Roxanne Khamsi joins Nels and Vincent discuss her first book, Beyond Inheritance, which explores how DNA continuously mutates throughout our lives, challenging the idea that our genetic destiny is fixed at birth.

Your DNA is changing all the time. Here’s why
We tend to think of the DNA strands that contain our genetic code as consistent, stable units. But in reality, the cells that make up our bodies are constantly replicating and changing. Even as you read this sentence, in fact, the genes within your cells are mutating. So, what causes these mutation…
Episode 167: Roxanne Khamsi on the Joy of Thinking
“I didn’t know I enjoyed thinking so much,” says science writer Roxanne Khamsi when asked what surprised her most about writing her first book Beyond Inheritance. “I thought I enjoyed interviewing people and reading research papers and the process of finding the right verb in a sentence. What’s har…
We Are All Mutants w/ Roxanne Khamsi
In this episode of Talk Nerdy, Cara is joined by science journalist, author, and contributing writer at The Atlantic, Roxanne Khamsi. We discuss her latest book, Beyond Inheritance: Our Ever-Mutating Cells and a New Understanding of Health. Follow Roxanne: @roxannekhamsi
Roxanne Khamsi: You are mutating – and that’s (mostly) a good thing
Mutations sound scary. But the DNA that shaped us is has been mutating since we were born. Some mutations are bad for our health while others are helping us stay alive, sprucing up our livers and fighting off germs.

TWiV 1341: Phage breaks and COVID origins
TWiV explains research that reveals dual activity of a phage-encoded lysin that modulates infection dynamics in a mycobacteriophage, and refutes a proposed link between the SARS-CoV-2 furin cleavage site and mouse-adapted MERS-coronavirus MA30.
Hosts: Vincent Racaniello, Kathy Spindler, Angela Min…

EP 1,283B - BEYOND INHERITANCE: Our Ever-Mutating Cells and a New Understanding of Health
For many decades, geneticists have focused on inherited mutations, but with BEYOND INHERITANCE: Our Ever-Mutating Cells and a New Understanding of Health (Riverhead Books, April 21, 2026) award-winning science writer Roxanne Khamsi shares a major shift in modern biology: the discovery that our DNA…
Your Cells Are Changing: Roxanne Khamsi on the DNA We Acquire as We Age
Right now, inside your body, cells are dividing.
Each time they divide, they must copy an enormous instruction manual: your DNA.
Most copies are remarkably accurate. Some acquire changes.
We tend to think of DNA as fixed. You receive it from your parents, carry it through life, and perhaps pass …
