Once a death sentence, cystic fibrosis now faces an apparent miracle cure. Follow the decades-long scientific quest, fueled by desperate parents, that led to this breakthrough with potential implications for the future of personalized medicine.

Brains might be the most complex structures on our planet – so how did evolution build them? To find out, rewind the clock three billion years to trace the evolutionary story of the dolphin, one of the smartest animals alive today. Discover how the first light sensing cells led to eyes that helped wire bodies to think, how a fluke viral infection supercharged the speed of thought, and how the neocortex emerged as early mammals re-wired their brains to attune to the night.

For millennia, Indigenous peoples in North America have practiced a unique form of science. From navigating the featureless Arctic to building energy-efficient homes in the desert, see how cultural traditions have led to remarkable innovations.

The relentless pursuit of energy, the very act of eating, has profoundly shaped life on Earth. Follow the evolution of the bat to discover the untold story behind every bite we take – one marked by astonishing evolutionary leaps revealing the strange origins of fundamental body parts like powerful jaws.

Hidden in the gorges of Southern France lies one of the most stunning decorated caves ever discovered: Chauvet, 'the Sistine Chapel of Paleolithic art.' For thousands of years, this geological wonder was visited only by animals. But around 37,000 years ago people arrived, and some covered its walls with drawings of exceptional beauty. Since its re-discovery in 1994, only a few scientists have been granted access to study it.

Earth teems with life in every imaginable form – creatures that walk, swim, slither, and fly. Some grow to astonishing size, like the elephant, while others boast extravagant adaptations, like the hummingbird’s long beak. How did evolution craft such a dazzling variety of body plans? To find the answer, trace life back to its ultimate ancestor, LUCA, and follow the innovations that shaped complexity.

An arms race is escalating above us, as military powers vie for control of space. Discover how satellites we rely on are vulnerable to attack, how debris is filling increasingly crowded orbits, and what can be done to protect them.

Sex changed everything – evolutionarily speaking, that is. By shuffling the genetic deck it unleashed variation, fueling diversity and throwing evolution into overdrive. But how did this radical innovation begin? From the first exchange of genes to the origins of males and females, uncover the evolutionary leaps that reshaped life.

Run. Leap. Swim. Pounce. Slither. Fly. Life moves in countless ways – but it wasn’t always this way. When animals first emerged, they clung to the seafloor, until a single twitch sparked a revolution. From the first muscle to the first heartbeat, from lobe fins that pushed life onto land to legs built for speed, movement reshaped the planet.
