Hank briefs us on a fascinating project that aims to map the anatomical and functional pathways of the brain - a neural network called the human connectome.

Humans are great at understanding medium-sized things, like how far the supermarket is from your house, or how to find the bathroom in the dark. But imagining distances in light-years is a lot harder -- so you'll have to use a trick or two.

Certain cognitive biases cause humans to make unsafe decisions in a pandemic, making a terrible disease even worse.

If we could find one silver lining to the pandemic, it's that we have come one step closer to answering some of the questions about our feline friends.

Is Your Brain Too Old For Video Games?

How can we begin to understand the way the brain works? The same way we begin to understand a city: by making a map. In this visually stunning talk, Allan Jones shows how his team is mapping which genes are turned on in each tiny region,...

A look into the science of concussions.

Hank explains the scientific reasons behind why we humans generally prefer to eat donut hamburgers to carrots.

This week, scientists revealed a sample of amber containing an extinct tick that fed on dinosaurs. Unfortunately, we can't take a blood sample from it and make Jurassic Park a reality, but it can still tell us a lot about how dinosaurs...

Sharks have been celebrated as powerful gods by some native cultures. And today, sharks are recognized as apex predators of the world's ocean. What is it that makes these fish worthy of our ancient legends and so successful in the seas?...

Whether they're belting Beyoncé, head-banging to classic rock, or rattling off curse words at zoo-goers, parrots are constantly astounding us. They are among the only animals that produce human speech, and some parrots do it almost...

For decades scientists believed that monkeys could not speak human language due to an anatomical difference in vocal tracts. Today, we're not so sure that this is the limiting factor after all.

In graphic design, Marian Bantjes says, throwing your individuality into a project is heresy. She explains how she built her career doing just that, bringing her signature delicate illustrations to storefronts, valentines and even...

Imagine the brain could reboot, updating its damaged cells with new, improved units. That may sound like science fiction - but it's a potential reality scientists are investigating right now. Ralitsa Petrova details the science behind...

Alzheimer's doesn't have to be your brain's destiny, says neuroscientist and author of "Still Alice," Lisa Genova. She shares the latest science investigating the disease -- and some promising research on what each of us can do to build...

They say everyone has a doppelganger, but is that really true? This week we meet a young woman who found her own look-alike, and figure out how we actually recognize faces.

Are parrots just good at imitating sounds or is there something else that separates them from other birds?

The human brain is puzzling -- it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her...

Planarians are flatworms most known for being able to grow a new head if it gets cut off, but perhaps even stranger is the fact that their new head retains some of the memories from the old one.

Many of the symptoms of menopause -- hot flashes, night sweats, insomnia, memory lapses, depression and anxiety -- start in the brain. How exactly does menopause impact cognitive health? Sharing groundbreaking findings from her research,...

We've been sending people to space since the '60s, and we're just now starting to learn what that does to their brains.

It's not rare to feel like we're dreaming, even right after we wake up, but when it sticks around for longer than it should, it can merit its own diagnosis: depersonalization-derealization disorder (DDD). Hank unpacks what this disorder...

More detailed brain scans reveal that the brain is more complicated than we thought! And cloned sheep might be healthier than we thought!

Some perfumers can distinguish individual odors in a fragrance made of hundreds of scents; tea-experts have been known to sniff out the exact location of a particular tea; and the NYC Transit Authority once had a employee responsible...
