Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia. But a revolution in bio-medicine is now offering new hope for the treatment of these ailments, and the potential to extend our lives still further. Methods such as gene editing and stem cell therapies are transforming the way medicine can conquer disease today. These extreme frontiers of medicine do, however, also come with a range of ethical dilemmas - when is the right time to try out an experimental technique on a patient? Should we gene edit human embryos? And is it right to use cells from aborted foetuses for medical treatments?

What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

Dr. Michio Kaku, the renowned theoretical physicist, walks through the evolutionary journey of quantum computing, from analog to digital to the quantum era. Quantum computers hold immense promise because of their ability to tap into parallel universes, which boosts their computational power exponentially. They could revolutionize agriculture, energy, and medicine, solving complex problems like creating efficient fertilizers, achieving fusion energy, and modeling diseases at the molecular level.

Beneath your ribs, you’ll find, among other things, the pancreas -- an organ that works a lot like a personal health coach.
Chris Packham invites us inside his autistic world to try to show what it is really like being him. For most of his life, broadcaster and naturalist Chris didn't tell anyone about the one thing that in many ways has defined his entire existence. Chris is autistic - he has Asperger's Syndrome, which means he struggles in social situations, has difficulty with human relationships and is, by his own admission, 'a little bit weird'. But what if there was a way of taking away these autistic traits? Would Chris ever choose to be 'normal'? Chris's long-term partner Charlotte discusses the problems Asperger's creates in their relationship, and Chris travels to America to witness radical therapies that appear to offer the possibility of entirely eradicating problematic autistic traits.

There’s a factory inside you that weighs about 1.4 kilograms and runs for 24 hours a day. It’s your liver: the heaviest organ in your body, which simultaneously acts as a storehouse, a manufacturing hub, and a processing plant.
Lyme disease, a mysterious tick-borne illness, is the fastest spreading vector-borne disease in the United States, and over the past decade, the tick that carries Lyme has been spreading across Canada with alarming speed. Ticked Off: The Mystery of Lyme Disease, is a fascinating and eye-opening documentary that explores a disease that has devastating effects, is often misdiagnosed and mistreated, and continues to be mired in a medical controversy. More than 30,000 cases are reported in the USA every year, but the real number could be as high as 300,000. And despite hard evidence that the Lyme-carrying, deer tick has already established populations across Canada, some people claim that patients here are still being told that they cannot contract Lyme in this country. Doctors agree that if it’s caught early Lyme disease can usually be cured with two to four weeks of antibiotics. There are others who believe that if it’s not caught early, the infection can develop into a debilitating condition they call Chronic Lyme. Yet unlike West Nile, Encephalitis or SARS, where the medical profession and scientists joined forces to find better treatments or a cure, many patients, who claim to have chronic Lyme, say that they are being denied treatment and left to suffer. So why is this happening?
