The human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells. It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it. Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death?

The opioid epidemic has devastated America. But what is the situation here? A new report from Public Health England raises serious concerns about Britain's own relationship with painkillers. Dr Michael Mosley embarks on an immersive journey to Britain’s opioid frontline and meets patients struggling with addiction and GPs fighting a constant battle to help those suffering from chronic pain. He also uncovers worrying evidence of people abusing over-the-counter opioids and discovers how easy it is to buy strong opioids online.

Gabriel is shocked to find out that when it comes to being overweight, it is not always your fault you are fat.
For 70 years we've waged war against harmful bacteria using antibiotics. But bacteria are fighting back and today more and more bacterial infections are becoming resistant to antibiotics. Drug-resistant superbugs are spreading; not just MRSA - also TB, pneumonia, e-coli. In Britain, hundreds are already dying of these infections - mainly the very young or the frail and elderly. But experts warn that unless we crack the problem, by 2050 we'll be facing a massive health crisis with over 10 million people dying of resistant bacterial infection worldwide every year.
