Dream Hacking: Decisions, Addictions, and Sleep Hero

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.

From lobster claws and dog teeth to bee stings and snake fangs, every creature depends on a weapon. But some are armed to extremes that make no practical sense—whether it’s bull elks with giant 40-pound antler racks or tiny rhinoceros beetles with horns bigger than their body. What explains giant tusks, horns, and claws that can slow an animal down and even impair health and nutrition? NOVA investigates the riddle of outsize weaponry and uncovers a bold new theory about what triggers an animal arms race. In creatures as varied as dung beetles and saber-toothed tigers, shrimp and elephants, the same hidden factors trigger the race and, once started, these arms races unfold in exactly the same pattern. Join scientists as they crack the secret biological code that underlies nature’s battleground.

Discover how a secret biological code has shaped nature’s battleground.

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?

Australia, the smallest of the seven continents, is the world capital of two of the three types of mammal on Earth: the marsupials, like the kangaroo and koala, which nourish their young in pouches, and the monotremes, featuring the platypus and the echidnas, which nourish their young in eggs. (The third variety, placentals, include all the rest of us—from mice to whales to people—which nourish their young in an advanced placenta.)

Why Addiction Stigma Stops Patients from Seeking Treatment Hero

What caused such dramatic changes at the ends of the Earth? And what can the past reveal about our planet’s climate today—and in the future? (Premiered February 5, 2020)

Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather, and many scientists agree. It’s the result of the weather machine itself—our climate—changing, becoming hotter and more erratic. In this two-hour documentary, NOVA will cut through the confusion around climate change. Why do scientists overwhelmingly agree that our climate is changing, and that human activity is causing it? How and when will it affect us through the weather we experience? And what will it take to bend the trajectory of planetary warming toward more benign outcomes? Join scientists around the world on a quest to better understand the workings of the weather and climate machine we call Earth, and discover how we can be resilient—even thrive—in the face of enormous change.

The 6 million-ton Great Pyramid of Giza is the last surviving wonder of the ancient world. How did the Egyptians engineer the mighty pharaoh Khufu’s tomb so precisely, with none of today’s surveying and power tools? And who were the thousands of laborers who raised the stones? Were they slaves or volunteers, and how were they housed, fed, and organized? &quot;Decoding the Great Pyramid&quot; presents the latest evidence from groundbreaking archaeological research that has transformed our understanding of the ancient world’s most ambitious engineering project, revealing a “lost city&quot; and intimate details of the lives of the laborers and officials who toiled on the vast construction. Amazingly, French archaeologists recently found the logbook of a labor team that delivered limestone blocks to build the Great Pyramid, yielding crucial insights into the planning and logistics behind the operation. Beyond these construction secrets, &quot;Decoding the Great Pyramid&quot; traces how mobilizing the colossal labor and resources invested in the monument transformed ancient Egypt, uniting a nation behind the common goal of ensuring eternity for the pharaoh and continuing prosperity for everyone in this life and the next.

Explore the intimate connections between the landscape, the colonizing of the continent, and the emergence of our industrial world. Beginning with Native American ancestors who crafted hunting weapons from stone traded across hundreds of miles, the program shows how pre-Columbian civilizations developed an expert knowledge of the landscape and its resources. With the arrival of Europeans, North America’s hidden riches became to key to prosperity, from the gold rush to today’s oil and gas boom. As a result, human activity has transformed the continent on a scale that rivals the geological forces that gave birth to it billions of years before. Yet, scientists warn of sleeping giants like the Cascadia fault, and the earthquake/tsunami one-two punch it could unleash on the Pacific Northwest. Even as we re-mold the continent to suit our needs, geologic processes inexorably continue, and they raise potential risks of catastrophe to our human civilization.

How has the land shaped our lives, from the arrival of the first Americans to today?

Making North America: Human

Our ancient human ancestors once lived only in Africa, in tiny bands of a few thousand hunter-gatherers. Then we moved out of our African cradle, spreading rapidly to every corner of the planet. How did we acquire the skills, technology and talent to thrive in every environment on earth? How did our prehistoric forebears cross the Sahara on foot, survive frigid ice ages, and sail to remote Pacific islands? “Great Human Odyssey” is a spectacular global journey following their footsteps out of Africa along a trail of fresh scientific clues. With unique glimpses of today’s Kalahari hunters, Siberian reindeer herders, and Polynesian navigators, we discover amazing skills that hint at how our ancestors survived and prospered long ago.
