NOVA: Episode 4
Tóm tắt
Without the chemistry of photosynthesis, ozone, and a molecule called Rubisco, none of us would be here. So how did we get so lucky? To find out, host David Pogue investigates the surprising molecules that allowed life on Earth to begin, and ultimately thrive. Along the way, he finds out what we’re all made of—literally.

Tập 3
Women 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.
Tập 5
NASA launches its most ambitious hunt for traces of life on Mars, landing a car-sized rover in a rocky, ancient river delta. The rover will stow samples for possible return to Earth and test technology that may pave the way for human travel to Mars.

Tập 2
Just about every solid, liquid, or gas in the world as we know it begins with reactions between individual atoms and molecules. Host David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that’s allowed farmers to feed a global population by the billions—a reaction that when reversed, unleashes the powerful chemistry of high explosives.
Tập 6
Women 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.
Tập 1
The value of DNA testing and the risks of entrusting this private data to commercial enterprises and online databases.
Tập 7
Coral 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.
Tập 8
What causes infertility, and how can assisted reproductive technologies help? Follow the journeys of people navigating fertility challenges from structural inequalities and racism to falling sperm counts, egg freezing, and IVF.
Tập 9
80 years after the world’s largest airship ignited in a giant fireball, newly discovered footage sparks a reinvestigation of what exactly caused the Hindenburg disaster.
Tập 10
Can 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?
Tập 11
Five 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.
Tập 12
Bats 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.
Tập 13
As state-legalized cannabis spreads, NOVA investigates the latest scientific evidence for its potential benefits and risks, and how criminalization has disproportionately harmed communities of color.
