"It's alive!" Since Dr. Frankenstein spoke those famous words, we've been alternately enthralled and terrified by the idea of creating life in the lab. Now, a revolution in genetic engineering and thrilling innovations in synthetic biology are bringing that dream—or nightmare, as the case may be—closer to reality. New tools allow researchers to use cells to create their own DNA and edit it into existing genomes with more ease and less cost than ever before. Along with renewed hopes for treating some genetic diseases, there's serious talk of using the newest technologies to bring long-extinct animals back from the dead – like the team hoping to resurrect the woolly mammoth. Science fiction is quickly becoming science fact. NOVA Wonders explores the benefits and the burden of risk surrounding the controversial new technology
In this episode, Ella Al-Shamahi explores the fate of the Neanderthals - asking why they became extinct, and discovering how they live on inside of us today. The programme starts in the caves of Gibraltar, which may have been the last place the Neanderthals survived. Discoveries here have shown the Neanderthals lived a good life - feasting on seafood and wild game. These were a people who were supremely well adapted to their environment. But about 40,000 years ago they disappeared. Why? One of the reasons might have been that they lost out in a physical showdown with modern humans. Ella investigates one of the world's oldest murder mysteries.
This first programme in a two-part series investigates what Neanderthals looked like and how they lived in their Ice Age world. It turns out that almost everything we thought we knew about them is wrong. They weren't hunched, grunting, knuckle-dragging ape-men at all. In reality they were faster, smarter, better looking - and much more like us than we ever thought. Our guide is Ella Al-Shamahi, a young, British, rising star in Neanderthal research, with an unusual side-line as a stand-up comic She enlists the skills of Andy Serkis, the global movie star and master of performance capture, best known as Gollum in the Lord of the Rings and Caesar in Planet of the Apes
The Mars InSight lander is on a 6-month journey to the Red Planet, with hopes of uncovering some of our planetary neighbor's secrets. Digging deep into Martian soil, the lander will measure marsquakes and also study the deep interior of Mars - perhaps revealing the origins of the planet.

Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches…the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?
Two male ocelots, among the rarest wild cats of the Pantanal, are fighting it out over a freshly killed anaconda. In the distance, the loudest land animal in the Western Hemisphere, the howler monkey, fills the air with its primal cry. There's excitement at every turn in this protected South American wetland.
While most of the series has focused on conflict, this episode is all about co-operation. The suitably named social spiders spin one enormous, 30m web for the whole colony, a queen bee rules her hive with a strict hierarchy and some green ants show great team spirit to help build a nest together. There are no broken societies here. David Attenborough shifts the focus to bugs that prefer cooperation rather than conflict. They include burrowing cockroaches, the suitably named social spiders - which share a 30-metre web.
Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up. The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics. The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge - someone who can write a new theory explaining the mystery of the dark energy.
How bad can our drinking pattern be for our health? Doctors and genetically identical twins Chris and Xand van Tulleken want to find out. With the current drinking guidelines under review, the twins embark on self-experimentation to see the effects of different drinking patterns on their health. With Chris drinking 21 units spread evenly across the week and Xand having his 21 in single weekly binges, how will their bodies differ after a month? Catching up with the latest research into alcohol drinking patterns, we ask if moderate drinking is genuinely good for us - and whether binge drinking is really that bad.
Join best-selling author Michael Pollan (Food Rules, The Botany of Desire) on a fascinating journey to answer the question: What should I eat to be healthy? Cutting through confusion and busting myths and misconceptions, In Defense of Food shows how common sense and old-fashioned wisdom can help us rediscover the pleasures of eating and avoid the chronic diseases so often associated with the modern diet. Pollan's journey of discovery takes him from the plains of Tanzania, where one of the world's last remaining tribes of hunter-gatherers still eats the way our ancestors did, to Loma Linda, California, where a group of Seventh Day Adventist vegetarians live longer than almost anyone else on earth, and eventually to Paris, where the French diet, rooted in culture and tradition, proves surprisingly healthy. Along the way he shows how a combination of faulty nutrition science and deceptive marketing practices have encouraged us to replace real food with scientifically engineered "food-like substances." And he explains why the solution to our dietary woes is in fact remarkably simple: Eat Food. Not Too Much. Mostly Plants.

Neuroscientist David Eagleman explores the human brain in an epic series that reveals the ultimate story of us, why we feel and think the things we do. This ambitious project blends science with innovative visual effects and compelling personal stories, and addresses some big questions. By understanding the human brain, we can come close to understanding humanity. Part 6: Who Will We be In ‘Who will we be?’ Dr. David Eagleman journeys into the future, and asks what’s next for the human brain, and for our species. Mother nature has evolved a brain that is eminently flexible, able to rewire itself according to whatever environment it finds itself in, which means that as technological advances continue apace, our technology is on a crash course with our biology.
Their beauty has captivated us for millennia. Their cost can be extraordinary–some are even considered priceless. Precious gems like diamonds, rubies, emeralds, opal, and jade are the ultimate treasures of the earth, and each one is made from a specific–and often torturous–recipe of chemistry, pressure, and heat. The secrets to their sparkle, color, and even strength lie deep inside the gems themselves, but could they also hold clues to one of the most enduring mysteries in the field of geology? From Tiffany’s workshop in New York to the sapphire mines of Sri Lanka, from North Carolina’s emerald fields to the jade-laden Forbidden City of China.
