Dark Matter - Turns out most of the universe is held together by a mysterious, invisible substance. Of Mice and Memory - Mice placed in enriched environments can recover lost memories, giving hope to those who study Alzheimer's. Profile: Hany Farid - This self-proclaimed "accidental scientist" is a digital detective inventing new ways to tell if photos have been faked. Wisdom of the Crowds - Ask enough people to estimate something, and their combined guesses will get you surprisingly close to the right answer.

Personal DNA Testing - Genetic testing to assess risk factors for a handful of serious illnesses is now commercially available. But is it a good idea? Art Authentication - See how clever computer algorithms can distinguish a master fake from a masterpiece. Capturing Carbon - An eighth-grader's science fair project prompts her scientist father to develop a new way to pull excess carbon dioxide out of the atmosphere. Profile: Pardis Sabeti - By night she's a rocker. By day, she's a Harvard geneticist tracking the evolution of the human genome.

Saving Hubble - Two teams of spacewalkers take on the risky mission of reviving the ailing Space Telescope. First Primates - Our most distant primate ancestors, which lived about 55 million years ago, were tree-dwellers the size of mice. Profile: Alfredo Quiñones-Hinojosa - He jumped the fence from Mexico to work as a farmhand and ended up a leading brain surgeon. Killer Microbe - A relatively benign bug becomes a highly lethal pathogen, known to U.S. soldiers as Iraqibacter.

Join astronomers hunting for Earth-like planets, see how computers distinguish authentic art from forgeries, meet a spider biologist who studies sexual cannibalism, and learn about genes that may be involved in causing autism.

Watch how an "exercise pill" turns couch-potato mice into athletes, explore a controversial new theory of what killed the dinosaurs, meet the first Latino-American astronaut, and find out why the beautiful northern lights signal a threat to our electronic society.

Can humans survive a trip to Mars and back that could take two to three years? This episode of NOVA scienceNOW examines all of the perils of this journey, including deadly meteoroids, bone and muscle deterioration, and cosmic radiation. Host Neil deGrasse Tyson checks in with scientists who are developing new ways to keep astronauts alive on such a journey. Among the innovations covered are meteoroid-proof materials, new space foods and spacesuits, and novel modes of transport, such as plasma rockets. This episode also profiles young female scientist and daredevil Vandi Verma, part of the team that drives the Mars rovers on the martian surface.

This provocative episode of NOVA scienceNOW examines whether we can slow down the aging process, looks at the latest on human hibernation, and checks in with bioengineers and a computer scientist inventing ways to keep us "going forever." Neil deGrasse Tyson also takes a lighthearted look at whether the tricks that have kept a 1966 Volvo running for 2.7 million miles can also help the human body go the extra mile.

This episode of NOVA scienceNOW delves into some pretty heady stuff, examining magic and the brain, artificial intelligence, magnetic mind control, and the work of neuroscientist and synesthesia researcher David Eagleman. Can we really believe our own eyes? Will machines one day think like us? Can magnetic wands effectively control brain functions and treat depression? Explore this and more.

Scientists have struggled for centuries to pinpoint the qualities that separate human beings from the millions of other animal species that have evolved on this planet. David Pogue explores the traits we once thought were uniquely ours—language, tool-making, even laughter—to uncover their evolutionary roots. He'll trace some of the crucial steps that transformed cave men to accountants, and find out if any of his own DNA came from a Neanderthal ancestor.

What's the secret to stopping crime? David Pogue gives the third degree to scientists pushing the limits of technology, not only to solve horrific murders but also to try to prevent crimes before they even happen. Pogue learns the latest techniques, from unraveling the clues embedded in a decomposing corpse, to detecting lies by peering directly into a suspect's brain, to tracking the creation of a criminal mind. And we meet a genius crime-stopper who has made some terrifying discoveries, including how easy it is for a bad guy to highjack not just your laptop but your kids’ toys, medical devices, even your car.

How do you get a genius brain? Is it all in your genes? Or is it hard work? Is it possible that everyone’s brain has untapped genius–just waiting for the right circumstances so it can be unleashed? From a man who can immediately name the day of the week of any date in history to a “memory athlete” who can remember strings of hundreds of random numbers, David Pogue meets people stretching the boundaries of what the human mind can do. Then, Pogue puts himself to the test: after high-resolution scanning, he finds out how the anatomy of his brain measures up against the greatest mind of the century: Albert Einstein.
