Explore the incredible regenerative capacity of salamanders, and see how they’re able to regrow limbs, hearts, and even brain tissue.

--

For some animals, losing a limb is a decidedly permanent affair. But for salamanders, particularly axolotls, amputation is just a temporary affliction. Not only can they grow back entire limbs in as little as six weeks, they can also regenerate heart and even brain tissue. So, how does this astonishing adaptation work? Jessica Whited explores the incredible regenerative capacity of salamanders.

Lesson by Jessica Whited, directed by Anton Bogaty.

Dig into the dangers of common kitchen appliances, and find out which could be the most hazardous to your health.

--

Between 2011 and 2022, the deadliest kitchen appliances in the US were ovens and ranges; taking lives by causing fires and leaking carbon monoxide. These kinds of sudden, catastrophic fatalities are thankfully rare. But the kitchen dangers that cause the most casualties may actually be less immediate, and more gradual. George Zaidan explores the safety of common kitchen appliances.

Lesson by George Zaidan, directed by Anastasiia Falileieva, Studio Plastic Bag.

Uploaded 30-01-14

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most information possible -- a feat that requires the entire brain. Richard E. Cytowic debunks this neurological myth (and explains why we aren't so good at multitasking).

Lesson by Richard E. Cytowic, animation by TOGETHER.

In ancient times, wildcats were fierce carnivorous hunters. And unlike dogs, who have undergone centuries of selective breeding, modern cats are genetically very similar to ancient cats. How did these solitary, fierce predators become our sofa sidekicks? Eva-Maria Geigl traces the domestication of the modern house cat.

McKenna Pope's younger brother loved to cook, but he worried about using an Easy-Bake Oven -- because it was a toy for girls. So at age 13, Pope started an online petition for the American toy company Hasbro to change the pink-and-purple color scheme on the classic toy and incorporate boys into its TV marketing. In a heartening talk, Pope makes the case for gender-neutral toys and gives a rousing call to action to all kids who feel powerless.

View full lesson: http://ed.ted.com/lessons/how-polarity-makes-water-behave-strangely-christina-kleinberg

Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating on water, Christina Kleinberg describes the effects of polarity.
