Jennifer Doudna:How CRISPR lets us edit our DNA

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but could also be used to create so-called "designer babies." Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to [...]

Moshe Szyf:How early life experience is written into DNA

Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to social factors like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring tell the child what kind of world they're going to live in, changing the [...]

Lifelike simulations that make real-life surgery safer

https://embed.ted.com/talks/peter_weinstock_lifelike_simulations_that_make_real_life_surgery_safer Critical care doctor Peter Weinstock shows how surgical teams are using a blend of Hollywood special effects and 3D printing to create amazingly lifelike reproductions of real patients — so they can practice risky surgeries ahead of time. Think: "Operate twice, cut once." Glimpse the future of surgery in this forward-thinking talk.
