  • Augmented
    E4
    AugmentedFollow the dramatic personal journey of Hugh Herr, a biophysicist working to create brain-controlled robotic limbs. At age 17, Herr’s legs were amputated after a climbing accident. Frustrated by the crude prosthetic limbs he was given, Herr set out to remedy their design, leading him to a career as an inventor of innovative prosthetic devices.
  • Determined: Fighting Alzheimer's
    E5
    Determined: Fighting Alzheimer'sFollow three women at risk of developing Alzheimer’s as they join a groundbreaking study to try to prevent the disease – sharing their ups and downs, anxiously watching for symptoms, and hoping they can make a difference.
  • Dinosaur Apocalypse: The New Evidence
    E6
    Dinosaur Apocalypse: The New EvidenceIn North Dakota, scientists use new fossils to reconstruct what life might have been like just before an asteroid wiped out the dinosaurs. The site reveals evidence, including the unhatched egg of a pterosaur, a huge flying reptile.
  • Dinosaur Apocalypse: The Last Day
    E7
    Dinosaur Apocalypse: The Last DayIn the second episode of this two-part series, the search continues for signs of what happened on the day the dinosaurs died. Scientists uncover extremely rare fossils and more evidence that could link the dig site in North Dakota to the asteroid that wiped out the dinosaurs 66 million years ago. Among the fossils are tiny spheres of glass locked in amber. Inside one of the spheres is a speck of rock that appears to be a chemical match to the killer asteroid itself. And scientists uncover one of the most spectacular finds of all: an almost perfectly preserved dinosaur leg. Sir David Attenborough guides us on a search for clues that could provide an unprecedented snapshot of what happened in the dinosaurs’ final moments on Earth.
  • Why Ships Crash
    E8
    Why Ships CrashWhen the bow of the colossal Ever Given container ship plowed into the bank of the Suez Canal on March 23, 2021, international supply chains ground to a halt. What went wrong? Follow the dramatic efforts to free the ship and the investigation into one of the most expensive shipping disasters ever. Maritime experts analyze other recent accidents and try to figure out how such devastating crashes could be prevented.
  • Ice Age Footprints
    E9
    Ice Age FootprintsThousands of ancient footprints stretch for miles across New Mexico’s White Sands National Park, capturing moments when Ice Age humans encountered now-extinct beasts, including mammoths and enormous ground sloths. These footprints tell an intimate story about what life was like during the Ice Age and reveal surprising new evidence about when humans arrived in North America.
  • Ultimate Space Telescope
    E10
    Ultimate Space TelescopeHow did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope—the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to “sniff” the atmospheres of exoplanets as we search for signs of life beyond Earth. But getting it to work is no easy task. The telescope is far bigger than its predecessor, the famous Hubble Space Telescope, and it needs to make its observations a million miles away from Earth—so there will be no chance to go out and fix it. That means there’s no room for error; the most ambitious telescope ever built needs to work perfectly. Meet the engineers making it happen and join them on their high stakes journey to uncover new secrets of the universe.
  • Saving Venice

  • Computers v. Crime
    E13
    Computers v. CrimeIn police departments and courts across the country, artificial intelligence is being used to help decide who is policed, who gets bail, how offenders should be sentenced, and who gets parole.
