NOVA brings you stories from the frontlines of science and engineering, answering the big questions of today and tomorrow, from how our ancestors lived, to whether parallel universes exist, to how technology will transform our lives.
Contrary to popular belief, dinosaurs never went extinct. They're still alive among us – in the form of birds! Birds are the only dinosaurs that survived the cataclysmic mass extinction caused by an asteroid the size of Mt. Everest crashing into Earth about 66 million years ago. The big question is: How? How did birds manage to not only live through the apocalypse, but also go on to diversify and populate every corner of our planet? Now, rare fossil discoveries are revealing the secrets of bird evolution going back more than 100 million years, telling the story of how some resilient feathered dinos persevered and transformed into the vast array of colorful bird species that fill our skies today.
An archaeological detective story opens a door into an extraordinary moment in the history of Ancient Egypt, as the discovery of a long-lost cemetery not far from King Tut's tomb shines a light on an often-overlooked Egyptian kingdom. Treasures emerge revealing details of a unique period about 2,700 years ago, when kings from Nubia – present-day Sudan – conquered Egypt and shifted the status of Egyptian women, giving them remarkable power. Archaeologists and historians reveal how the ascent of The God's Wife of Amun lifted some women to the highest echelons of religious, political, and financial power in the ancient Egyptian empire.
For over two centuries, archaeologists have hailed Pompeii as a sophisticated city at the heart of an advanced ancient civilization. But a series of new excavations is painting a much more complex picture of the city tragically buried by the eruption of Mount Vesuvius in 79 CE. New archaeological finds – including 2,000-year-old lines of graffiti, human remains, and artifacts from ancient homes and businesses – are revealing a city of both staggering wealth and extreme poverty, dependent on slavery, and riven by political conflicts, violence, and riots. Before Vesuvius rumbled, the jewel of the ancient Roman Empire hid a very dark side.
On March 26, 2024, the world collectively gasped as a massive container ship, the Dali, lost control and plowed into the landmark Francis Scott Key Bridge in Baltimore. The busy four-lane bridge suffered a catastrophic collapse and crashed into the Patapsco River. Six highway workers were killed, and the Port of Baltimore – a crucial link in the global shipping chain on the Eastern Seaboard of the United States – was blocked by thousands of tons of twisted steel and concrete. How did a modern ship lose all power and propulsion? And why did the bridge fail so catastrophically? Follow the high-stakes rescue and recovery, the efforts to reopen the port, and the investigations into what went wrong and how many other crucial bridges are at risk.
In 1775, a ragtag army of farmers and tradesmen went to war against the most powerful army in the world, ultimately winning American independence. What military technologies did the American colonies use in their fight for freedom, and how did they help propel them to one of history's most unlikely victories? Archaeologists and historians uncover the real stories of innovation, skill, and strategy that determined the outcome of important battles. From the Brown Bess musket to the world's first military submarine, get a closeup look at the powerful and sometimes ingenious weapons that helped the colonies win the war.
Can forests help cool the planet? Follow scientists working in spectacular forest landscapes in Costa Rica, Brazil, Australia, and beyond as they try to untangle complex networks of trees, fungi, and creatures large and small – all in a quest to tackle the twin threats of climate change and species extinction.
Black Americans are nearly twice as likely to have high blood pressure, diabetes, and heart disease than White Americans, and their life expectancy is about five years shorter. Why? In this special feature-length documentary, Oscar-nominated filmmaker Stanley Nelson investigates the dramatic health disparities in the U.S., even as scientists confirm that there are no meaningful genetic differences between races. From the deep history of pseudoscientific beliefs about race that still permeate modern medicine, to the latest research on how experiencing discrimination can directly damage the body's DNA and biology, "Critical Condition" reveals the factors behind the health crisis facing Black Americans.
Surprisingly little is known about the behavior of cars and drivers in uncontrolled, real-world accidents, despite rigorous testing in laboratory-controlled crashes. Now, a first-of-its-kind experiment aims to discover what really happens in a multi-vehicle pileup and how cars and driving could be made safer. In the first episode of this two-part special, go behind the scenes as scientists make a series of high-stakes decisions to ensure the ambitious experiment goes off without a hitch. They only have one shot. The plan is for eight drivers to drive eight different types of cars by remote control at 70 mph down a hazardous roadway.
In the second episode of this two-part special, forensic analysis is put to the test in a first-of-its-kind experiment to discover what really happens in a multi-vehicle pileup. Real-life crash scene investigations have very little data to work with, so are they accurate? And what can we learn about car safety when there is actual data to show exactly what happened? Follow scientists, engineers, and accident investigators as they analyze a treasure trove of data – more than they've ever had before. In this unprecedented look at a major multi-vehicle accident, discover insights about driver behavior and vehicle design that could save lives.
Looks like something went completely wrong!
