NOVA scienceNOW is a News magazine version of the long-running and venerable PBS science program Nova. Premiering on January 25, 2005, the series was originally hosted by Robert Krulwich, who described it as an experiment in coverage of "breaking science, science that's right out of the lab, science that sometimes bumps up against politics, art, culture". At the beginning of season two, Neil deGrasse Tyson replaced Krulwich as the show's host. Tyson announced he would leave the show and was replaced by David Pogue beginning season 6.

Explorer Robert Ballard sets out to solve the mystery of Amelia Earhart's disappearance as he and a team of experts travel to the remote Pacific atoll named Nikumaroro in search of her final resting place.

At a shipyard on Germany's North Sea, a marvel of modern engineering is taking shape; hundreds of construction workers, engineers, architects, designers, animators, cast and crew are transforming 144,000 tons of steel.

Bob Ballard reveals the inside stories behind his most exciting discoveries, while sharing the personal triumphs, challenges and tragedies that led him to them.

Discover the evolutionary secrets of some of the world’s most majestic creatures. From voracious crocodiles and acrobatic birds to stupendous whales and majestic elephants, this documentary follows top scientists on a global adventure as they follow clues from the fossil record and change what we thought we knew about the evolution of iconic beasts.

Dr Spencer Wells retraces the footsteps of 200 random New Yorkers and proves they are all cousins. On the most diverse street in the most diverse city in the most diverse country in the world, a team of National Geographic scientists swab the cheeks of some 200 random New Yorkers. The goal: to retrace our ancestral footprints and prove we are all cousins in the “family of man.” Cutting edge science, coupled with a cast of New Yorkers – each with their own unique genetic history - will help paint a picture of these amazing journeys. Ultimately, Man’s First Migrations answers some of humanity’s most burning questions, such as who we are and where we come from, and forces us to change how we think not only about our relationships with our neighbours, but ourselves.

On a summer's night, there's nothing more magic than watching the soft glow of fireflies switching on and off. Few other life forms on land can light up the night, but in the dark depths of the oceans, it's a different story: nearly 90% of all species shine from within. Whether it's to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths, and scientists are finally starting to decode it.

A team of palaeontologists led by Nizar Ibrahim go in search of Spinosaurus, a giant meat eater believed to be even larger than Tyrannosaurus rex.
