Sex is the key to the immortality of genes, and any tactic necessary will be deployed in the cause of reproduction - even if it's suicidal to the participant. This episode explores many of the most ingenious, complex, and dramatic methods that animals employ to ensure the continuation of their genetic line.

The story of how the secret of life has been examined through the prism of the most complex organism known - the human body. It begins with attempts to save the lives of gladiators in Ancient Rome, unfolds with the macabre work and near-perfect drawings of Leonardo in the Renaissance, through the idea of the 'life force' of electricity, to the microscopic world of the cell. It reveals how a moral crisis unleashed by work on the nuclear bomb helped trigger a great breakthrough in biology - understanding the structure and workings of DNA.

2020 has been an unprecedented year in science. From a global pandemic and race to find a cure, to exploring our planetary neighbours and our own world, stay in the know with the latest stories that defined this tumultuous year. 365 days marked by stark warnings about the planet's future and technological triumphs. During this journey around the sun, science continued to reveal stories of our past and also provide promise that we can overcome the obstacles in way some far ahead and others more immediate.

'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. Another daring genetic experiment to bioengineer animals could prevent Lyme disease. But the power to make life comes with deep ethical questions. What are the potential rewards—and dangers—of tinkering with nature? This films explores the benefits and the burden of risk surrounding the controversial new technology.

Join investigators as they untangle the cause of Alzheimer’s and race to develop a cure. Alzheimer’s disease strikes at the core of what makes us human: our capacity to think, to love, and to remember. The disease ravages the minds of over 40 million victims worldwide, and it is one of the greatest medical mysteries of our time. Join investigators as they gather clues and attempt to reconstruct the molecular chain of events that ultimately leads to dementia". Follow key researchers in the field who have helped to develop the leading theories of the disease. Along the way, meet individuals from all walks of life who will reveal what it’s like to struggle with Alzheimer’s. Among them, members of a unique Colombian family who have learned that their genetic predisposition all but guarantees early onset Alzheimer’s. Yet there may be hope. Join these courageous patients participating in clinical trials, and then go behind the scenes of the major drug trials to see how researchers target and test therapies that may slow and even prevent Alzheimer’s

Humanity’s potential seems limitless. But could we become as powerful as God? Scientific breakthroughs grant our species seemingly divine abilities. Biologists tinkering with DNA are figuring out ways to grow new life forms, while neuroscientists try to create artificial consciousness. Statisticians around the world are using big data to predict the future and computer scientists have discovered a "God algorithm" that could solve any global problem in an instant. But to truly become God, we not only have to be all knowing, but all being. Quantum physicists are figuring out how to teleport matter at the speed of light!
