More than one million immigrants have been deported since President Obama took office. Under his administration deportations and detentions have reached record levels. The get-tough policy has brought complaints of abuse and harsh treatment, including charges that families have been unfairly separated after being caught in the nationwide dragnet. The administration has promised to make the detention system more humane, and more selectively target the most serious criminals. But it faces Republican critics urging stricter measures - and a growing backlash among Latino voters, a key 2012 electoral force. In a co-production with the Investigative Reporting Workshop, correspondent Maria Hinojosa investigates Obama's enforcement strategies and journeys into the secretive world of immigrant detention, with a penetrating look at who is being detained and what is happening to them.

In the fall of 2001, envelopes carrying deadly anthrax were delivered to US Senate offices, network news divisions, and a tabloid newspaper. Five people were killed, many more infected, and the nation was terrorized. Seven years later, after mistakenly pursuing one suspect, one of the most expensive and complex investigations ever undertaken by the FBI ended when they identified Army scientist Dr. Bruce Ivins as the sole perpetrator of the attacks - after Ivins had taken his own life. Now, new questions are being raised about the FBI's investigative methods and whether Ivins really did it. FRONTLINE, in a co-production with ProPublica, and McClatchy Newspapers, takes a hard look at the FBI's investigation of the country's most notorious act of bioterrorism.

Modern humans have been around for some 200,000 years, which is peanuts compared to some of the species alive today: there are creatures that have been with us since the Cambrian age and trees that have barely changed in the last 300,000 years. Natural history palaeontologist Richard Fortey investigates why certain life forms endure..

During construction at a Colorado ski resort, a bulldozer dug up something strange: a tooth so huge it had to be held in two hands. Racing to the scene, scientists from the local Denver museum could scarcely believe what they found: a vast trove of fossils from the depths of the Ice Age 100,000 years ago, when North America teemed with incredible beasts: massive mastodons, saber tooth cats and camels, giant bison with six-foot horns, and ground sloths as big as elephants with huge claws. Packed with ingenious scientific work and spectacular fossils, NOVA's Ice Age Death Trap reveals intimate secrets of the life and death of North America's most exotic and extreme creatures. Most tantalizing of all, the team unearths startling and controversial evidence of what may be the earliest humans ever to venture into the untamed wilderness of Ice Age America.

Penty and his family are members of the Guarani tribe from the community of Bameno in the heart of the Amazon forest.

When the lights go down in cities across North America, another world is revealed, populated by shady little characters that live alongside us, but exist in the margins. These pint-size problem solvers are smart, adaptable and omnivorous, and they love a good challenge. Welcome to the world of urban raccoons. With their busy little hands, they can do what other would-be urban animals can’t — open doors, get into attics, and raid secured trash cans. And they are especially fond of big cities, like Chicago, New York, and Toronto — the raccoon capital of the world. In cities everywhere, wherever they’ve been introduced, they have done very, very well.

It is estimated that 99 per cent of species have become extinct and there have been times when life's hold on Earth has been so precarious it seems it hangs on by a thread. This series focuses on the survivors - the old-timers - whose biographies stretch back millions of years and who show how it is possible to survive a mass extinction event which wipes out nearly all of its neighbours. The Natural History Museum's Professor Richard Fortey discovers what allows the very few to carry on going - perhaps not for ever, but certainly far beyond the life expectancy of normal species. What makes a survivor when all around drop like flies? In this episode Professor Fortey focuses on a series of cataclysms over a million year period, 250 million years ago.
