How the heart actually pumps blood - Edmond Hui

For most of history, scientists weren’t quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer

How sugar affects the brain - Nicole Avena

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more.

What triggers a chemical reaction? - Kareem Jarrah

Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by examining the two underlying forces that drive both

Nature's smallest factory: The Calvin cycle - Cathy Symington

A hearty bowl of cereal gives you the energy to start your day, but how exactly did that energy make its way into your bowl? It all begins with photosynthesis, the process that converts the air we breathe into energizing glucose. Cathy Symington details the highly efficient second phase of

What is dyslexia? - Kelli Sandman-Hurley

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

Feedback loops: How nature gets its rhythms - Anje-Margriet Neutel

While feedback loops are a bummer at band practice, they are essential in nature. What does nature’s feedback look like, and how does it build the resilience of our world? Anje-Margriet Neutel describes some common positive and negative feedback loops, examining how an ecosystem’s many loops come

How does your brain respond to pain? - Karen D. Davis: Everyone experiences pain -- but why do some people react to the same painful stimulus in different ways? And what exactly is pain, anyway?

How does your brain respond to pain? - Karen D. Davis

Everyone experiences pain -- but why do some people react to the same painful stimulus in different ways? And what exactly is pain, anyway? Karen D. Davis walks you through your brain on pain, illuminating why the “pain experience” differs from person to person.

How to sequence the human genome - Mark J. Kiel

Your genome, every human's genome, consists of a unique DNA sequence of A's, T's, C's and G's that tell your cells how to operate. Thanks to technological advances, scientists are now able to know the sequence of letters that makes up an individual genome relatively quickly and inexpensively. Mark

Via Ted-Ed: What percentage of your brain do you use? - Richard E. Cytowic debunks this neurological myth that we only use of our brains (and explains why we aren’t so good at multitasking).

What percentage of your brain do you use? - Richard E. Cytowic

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

What makes tattoos permanent? - Claudia Aguirre

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

Dead stuff: The secret ingredient in our food chain - John C. Moore

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how

The mysterious workings of the adolescent brain - Sarah-Jayne Blakemore

Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically “teenage” behavior is caused by the growing and developing brain.
