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.
Meet people struggling with infertility and the challenges of assisted reproduction.

Some five centuries ago, a major revolution overturned traditional ship design: in just a few years, ships were transformed from small coastal-bound transports into massive ocean-going vessels. Once regular trans-oceanic travel became feasible, everything changed. Powerful navies arose and fought for supremacy at sea, while the new ships enabled empire-building European powers to invade and colonize Indigenous lands and exploit their peoples. How did this transformative change in ship design come about? Scholars and historians have always faced a problem: few wrecks dating back to this crucial period survive, so rough drawings and incomplete records have been their only evidence. Now, a well-preserved wreck off the coast of Sweden dating back to the era of Columbus reveals new details about the engineering that changed the world. Dive with NOVA as we recover the sunken clues to this significant new discovery.

Outnumbering 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.

Join 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.

From 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 can, pound for pound, deliver 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?

Explore ancient Maya cities and learn why their inhabitants abandoned them.
The 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. The evidence also testifies to the survival and resilience of the Maya people, whose traditions and creativity continue to enrich the world today.
