How a wound heals itself

AdultsBiologyHealthHumanWellnessScience
Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults. When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.

What is dyslexia?

AdultsLanguageScienceEducationDisabilityNeuroscience
Dyslexia affects up to 1 in 5 people, but the experience of dyslexia isn't always the same. This difficulty in processing language exists along a spectrum -- one that doesn't necessarily fit with labels like "normal" and "defective." Kelli Sandman-Hurley urges us to think again about dyslexic brain function and to celebrate the neurodiversity of the human brain.

Myths and misconceptions about evolution

AdultsEnvironmentHistoryWorldScienceBiologyEducationEvolution
How does evolution really work? Actually, not how some of our common evolutionary metaphors would have us believe. For instance, it's species, not individual organisms, that adapt to produce evolution, and genes don't "want" to be passed on -- a gene can't want anything at all! Alex Gendler sets the record straight on the finer points of evolution.

How do pain relievers work?

The Most Radioactive Places on Earth

AdultsGlobal WarmingLifeWorldScienceTelevisionHistoryEnergySociety
I'm filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren't as radioactive as you'd think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also visited nuclear power plants, research reactors, Marie Curie's institute, Einstein's apartment, nuclear medicine areas of hospitals, uranium mines, nuclear bomb sites, and interviewed numerous experts.

What makes tattoos permanent?

AdultsArtGadgetsScienceCultureHistoryBiology
The earliest recorded tattoo was found on a Peruvian mummy in 6,000 BC. That's some old ink! And considering humans lose roughly 40,000 skin cells per hour, how do these markings last? Claudia Aguirre details the different methods, machines and macrophages (you'll see) that go into making tattoos stand the test of time.
