- Picture a Scientist/ Search Engine Breakdown
第 6 集Picture a Scientist/ Search Engine BreakdownWomen make up less than a quarter of STEM professionals in the United States, and numbers are even lower for women of color. But a growing group of researchers is exposing longstanding discrimination and making science more inclusive. - Reef Rescue
第 7 集Reef RescueCoral reefs are not just beautiful, they are also home to over a quarter of all marine life and are crucial to human societies around the globe. But as the climate changes and oceanic heat waves become commonplace, corals are bleaching and reefs are dying off. Now, marine biologists from across the world are teaming up to counteract this catastrophe with a technique called assisted evolution. Follow scientists as they attempt to crossbreed heat-resistant corals, and even transplant corals’ algae, in a race to save the coral reefs from extinction. - Great Electric Airplane Race
第 10 集Great Electric Airplane RaceCan new emission-free electric planes replace our polluting airliners and revolutionize personal transportation in our cities? NOVA takes you for a ride in some impressive prototypes that are already in the air, from speedy single-seat planes that can take off like a helicopter but are half as noisy to “self-flying” air taxis that are already taking passengers on test flights in Chinese cities. But if electric airplanes are ever to advance beyond small, short-haul craft, significant hurdles of battery weight, energy storage, and cooling remain to be overcome. How long will it be before the dream of super-quiet, super-efficient airliners becomes a reality? - Ship That Changed the World
第 11 集Ship That Changed the WorldFive centuries ago, the Age of Exploration and Europe’s imperial colonization of far-off lands was launched by a revolution in ship design that made long-distance ocean voyages practical. But exactly how this momentous innovation happened eludes historians. Now, the excavation of a rare intact wreck discovered off the coast of Sweden offers vital new clues to a maritime mystery. - Bat Superpowers
第 12 集Bat SuperpowersBats have been implicated in deadly epidemics such as COVID-19 and Ebola, yet scientists are discovering evidence that they may hold a key to a longer and healthier life. From caves in Thailand and Texas to labs around the globe, NOVA meets the scientists who are decoding the superpowers of the bat. - Particles Unknown
第 14 集Particles UnknownOutnumbering atoms a billion to one, neutrinos are the universe’s most common yet most elusive and baffling particle. NOVA joins an international team of neutrino hunters as they try to capture an elusive fourth form of neutrino. Their results may force scientists to redraw their blueprint of the subatomic world, the Standard Model of physics, and change our understanding of how the universe works. - Arctic Drift
第 15 集Arctic DriftJoin scientists on the most ambitious Arctic research expedition of all time. Experts from over twenty different nations join the voyage of the massive Polarstern icebreaker as it’s gripped by the polar ice and drifts for nearly an entire year. From this unique research station, they can make long-term observations and perform experiments in unprecedented detail. Facing hungry polar bears, perilous sea ice cracks, and brutal cold, the team strives to understand the forces that are changing the region—and the world—forever. - Edible Insects
第 16 集Edible InsectsFrom crunchy crickets to nutty fly grubs, NOVA takes a tasty look at insect foods and how they could benefit our health and our warming planet. From Thailand to Texas, insect farmers are showing how the tiny critters stack up as an environmentally friendly alternative to beef protein and, pound for pound, deliver far better nutritional value than the finest steak. But will Americans overcome the “ick” factor and share the appetite of many cultures around the world for insect feasts? - NOVA Universe Revealed: Age of Stars
第 17 集NOVA Universe Revealed: Age of StarsThe sun is our life-giving source of light, heat, and energy, and new discoveries are unraveling its epic history. Join NOVA on a spectacular voyage to discover the sun’s place in a grand cycle of birth, death and renewal that makes this the age of stars. Witness how stars of every size and color came to populate our universe; how stars stage a dramatic exit when they explode as supernovae, which can outshine an entire galaxy; and how, billions of years in the future, the age of stars will lead ultimately to an age of darkness. - NOVA Universe Revealed: Alien Worlds
第 19 集NOVA Universe Revealed: Alien WorldsIt’s an age-old question: are we alone? Or do other lifeforms and intelligences thrive on worlds far beyond our own? Ultra-sensitive telescopes and dogged detective work are transforming alien planet-hunting from science fiction into hard fact. Join NOVA on a visit to exotic worlds orbiting distant suns, from puffy planets with the density of Styrofoam to thousand-degree, broiling gas giants. Most tantalizing of all are the Super-Earths in the “Goldilocks zone,” just the right distance from their sun to support life, and with one of them signaling life’s essential ingredient, water, in its atmosphere. Are we on the brink of answering that haunting question? - NOVA Universe Revealed: Black Holes
第 20 集NOVA Universe Revealed: Black HolesTake a seat on the ultimate thrill ride to explore nature’s strangest and most powerful objects. Black holes can reshape entire galaxies, warp the fabric of space and time, and may even be the key to unlocking the ultimate nature of reality. A new generation of high-energy telescopes is bringing these invisible voids to light, showing that “supermassives” millions or billions of times larger than our sun lurk at the center of nearly every galaxy, including our own. But what happens if you stray too close to one? And what lies beyond the black hole’s abyss? If nothing can ever escape it, is that the end of the story? Or could they be a portal to another dimension—or another universe, full of black holes? - NOVA Universe Revealed: Big Bang
第 21 集NOVA Universe Revealed: Big BangThe Big Bang is when many think the universe started and time itself began. But what clues can we discover about this ultimate genesis of everything? And can we ever know what existed before the Universe’s birthday? With stunning animation based on space telescope images, NOVA explores infant galaxies filled with violent blue stars that formed just a few hundred million years after the Big Bang. Before that—before the coming of visible light itself—stretch the “cosmic Dark Ages.” But scientists haven’t stopped there; instead, they’ve come up with an incredible theory for what happened billionths of a billionth of a second from the universe’s birth. If they’re right, we’re on the brink of understanding more than we could ever have hoped about our cosmic origins. - Butterfly Blueprints
第 23 集Butterfly BlueprintsThe hidden scientific secrets of butterflies reveal them to be more inventive and resilient than we ever imagined. Follow their extraordinary life cycle and migrations to tropical rainforests, windswept prairies, and even inside a chrysalis as it’s being spun. - Ancient Maya Metropolis
第 25 集Ancient Maya MetropolisThe ancient ancestors of today’s Maya people thrived in large sophisticated cities across Central America for centuries. Why, around 750 CE, did they begin to abandon many of their major cities? Archaeologists investigate dramatic new evidence of the catastrophic droughts and instability that pushed cities beyond their limits.
