Join us as NOVA tags along on the quest for evidence of life on Mars, into the bizarre world of slime molds, and on the complex and controversial roads created by DNA testing.
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 a possible return to Earth and test technology that may allow humans to travel to Mars.
NASA launches its most ambitious search yet for traces of ancient life on Mars.
Meet slime molds: the brainless blobs that can learn, make decisions, and navigate mazes.
Scientists investigate the bizarre intelligence of slime molds, which appear to learn and make decisions — without a brain. These cunning, single-celled blobs can navigate mazes and create efficient networks. Can they also redefine cognition?
Some 30 million Americans have sent their DNA to be analyzed by companies like 23andMe and AncestryDNA. But what happens once the sample is in the hands of testing companies, and how accurate are their results? NOVA explores the power of genetic data to reveal family connections, ancestry and health risks — and even solve cold criminal cases.
What can DNA testing companies reveal about our ancestry and health, and at what risk?
