One very dry demo

Mark Shaw demos Ultra-Ever Dry, a liquid-repellent coating that acts as an astonishingly powerful shield against water and water-based materials. At the nano level, the spray covers a surface with an umbrella of air so that water bounces right off. Watch for an exciting two-minute kicker.

Making matter come alive

Before life existed on Earth, there was just matter, inorganic dead "stuff." How improbable is it that life arose? And -- could it use a different type of chemistry? Using an elegant definition of life (anything that can evolve), chemist Lee Cronin is exploring this question by attempting to create a fully inorganic cell using a "Lego kit" of inorganic molecules -- no

A new superweapon in the fight against cancer

Cancer is a very clever, adaptable disease. To defeat it, says medical researcher and educator Paula Hammond, we need a new and powerful mode of attack. With her colleagues at MIT, Hammond engineered a nanoparticle one-hundredth the size of a human hair that can treat the most aggressive, drug-resistant cancers.

New nanotech to detect cancer early

What if every home had an early-warning cancer detection system? Researcher Joshua Smith is developing a nanobiotechnology "cancer alarm" that scans for traces of disease in the form of special biomarkers called exosomes. In this forward-thinking talk, he shares his dream for how we might revolutionize cancer detection and, ultimately, save lives.

What you need to know about CRISPR

Should we bring back the wooly mammoth? Or edit a human embryo? Or wipe out an entire species that we consider harmful? The genome-editing technology CRISPR has made extraordinary questions like these legitimate but how does it work? Scientist and community lab advocate Ellen Jorgensen is on a mission to explain the myths and realities of CRISPR, hype-free, to the
