Have you ever felt drawn toward choices without knowing why? Or, as seen in the movie “Inception,” have you ever felt like you’ve woken up with a decision that’s already been made for you?Neuroscience is beginning to demystify such feelings. Our agency and decisions, it turns out, can be measurably influenced by events that evade the conscious part of our brains. We’ll see three groundbreaking experiments that illustrate that influences we are unaware of in our waking life, during dreamless sleep, or even in our dreams can impact our memory and behavior.Published on February 18, 2021, in the journal Current Biology, an international team of scientists have found a bridge to the dream world by showing that it’s possible to have a direct dialogue with someone in their dream—and NOVA’s Greg Kestin (host of “What the Physics?!”) was given exclusive access.The scientific context and potential effect of this team’s work are built up in the film through two related groundbreaking experiments. These experiments also show how scientists can influence your decisions, desires, and habits without you being aware.

What is The Nature of Reality? It’s a blog, and it’s pretty much the biggest question we could think of. We can’t promise that we’ll answer the question once and for all – in fact, we can pretty much guarantee that we won’t – but we promise a space that welcomes big ideas about space, time, and the universe; where we take questions as seriously as we take answers; where physics is about way more than inclined planes and levers and pulleys. Stick around; we just might expand your cosmic horizons.

The search for extraterrestrial life is an age-old quest. But recent breakthroughs make today an era like no other in the history of astronomy. From the exhilarating probing of our own solar system and the Kepler mission’s astounding discovery of thousands of extrasolar planets, to the next-generation telescopes under development, the prospects for finding life beyond Earth have never been stronger. Still, daunting hurdles remain. How can we study anything light years away, let alone a little planet? In the vast universe, where should we even start to look? Is our failure to hear any other voices in the galaxy a sign that we are special? NOVA Wonders joins leading explorers now searching the galaxy for life and intelligence on other planets—and asks, if we do find other life in the universe…what would that mean?

This parasite can also infect humans by way of cat feces. Although Toxoplasma research is still in its early stages, scientists estimate that one-third of the human population has been infected.

What do fossilized leaves, an asteroid, and Florida sinkholes have in common? Dr. Kirk Johnson is Sant Director at the Smithsonian Institution, National Museum of Natural History, and has the answers. Kirk oversees one of the largest natural history collections on the planet – and he’s spent his career digging into the story of life on Earth across millions (and billions) of years. In this episode, Hakeem and Kirk explore the science of “deep time,” how fossils actually form, and the surprising origins of Earth’s oceans. Plus, Kirk shares some hot tips on fossil hunting and how to count the number of leaves on a tree…because you never know when you might need these skills.Subscribe now wherever you get your podcasts so you never miss an episode.<a href="https://podcasts.apple.com/us/podcast/particles-of-thought/id1832615266">Apple Podcasts</a> <a href="https://open.spotify.com/episode/2H4ljWvZTjGQVwV7Zv0TlS">Spotify</a> <a href="https://music.amazon.com/podcasts/4419429a-ad9f-471f-bb85-7416cf2412e2/episodes/650b6bff-9383-4262-9792-9526cdae501d/nova-presents-introducing-particles-of-thought">Amazon Music</a>

Leonardo da Vinci was a Renaissance genius. Not only did he paint masterpieces of art, but he was an obsessive scientist and inventor, dreaming up complex machines centuries ahead of his time, including parachutes, armored tanks, hang gliders, and robots. On the 500th anniversary of Leonardo’s death, with the help of biographer Walter Isaacson, NOVA investigates the secrets of Leonardo’s success. How did his scientific curiosity, from dissections of cadavers to studies of optics, shape his genius and help him create perhaps the most famous painting of all time, the "Mona Lisa"? (Premiered November 13, 2019)

NOVA revolves around a simple premise: the world of science is exciting! For NOVA viewers, science means adventure and exploration--because from ants to aliens, this weekly documentary series probes the far reaches of earth, sea and stars.  NOVA proves that science is neither secret lore nor sacred ritual but rather, at its heart, a lifelong journey of discovery.

252 million years ago, the most devastating mass extinction of all time abruptly wiped out around 90% of all species on Earth. The culprits were the biggest volcanic eruptions the world has ever seen, emitting some 700 thousand cubic miles of magma and rock. Volcanic gasses permeated the atmosphere and acidified the oceans while toxic gasses destroyed the ozone layer, bathing the planet in destructive UV radiation. The event – now called “The Great Dying” – came close to wiping out all life on the planet. Follow scientists as they piece together geologic evidence from the deep past and clues from today’s ecosystems to discover how life made it through and evolved into the astonishing variety we see around us today. Premiering October 25 at 9 pm on PBS.
