The Virus Hunters • 2008

Category: Health | Torrent: | Subtitle:

On the front lines of the hunt for killer viruses, a shocking discovery is made: viruses, once thought to be a menace to humankind, may in fact be the ultimate creators. Since the beginning of time, they have played a critical role in evolution, shaping us and perhaps even creating us. How could that be? How can an entity seemingly programmed for destruction lead to genetic diversity and new species? To many people, viruses are simply agents for disease, but to Dr. Luis Villarreal, Director of the Center for Virus Research at the University of California Irvine, they may possess far greater power than originally thought. He guides us through evidence that viruses gave rise to the first complex cells, played a role in the diversification of life, changed how our young are born, drove evolution, and perhaps gave us emotions. One expert even suggests that an ancient virus could have entered our genes and rewired us for monogamy. National Geographic investigates a provocative new theory that suggests that all life - including humans - is descended from viruses. Taking us through African jungles in search for new strains, this episode of Explorer presents a startling new view of viruses - toward what may be a remarkable evolutionary moment: the rise of a new human species.

Two procedures so formidable, they would not have been attempted even a few years ago. Surgical teams at the Queen Elizabeth are constantly pushing the limits of what is possible. But despite state-of-the-art diagnostic scanning, sometimes cancer surgeons don't know exactly what they are up against until they open the patient up on the operating table. Even with the most meticulous planning, sometimes they must resort to taking critical decisions live in the theatre. 74-year-old Jasmine Harkness has been referred to the specialist sarcoma unit with a vast tumour in her abdomen, weighing more than three stone - a third of her total body weight. It is consuming her, displacing organs including her stomach and liver. Unless it can be removed, she has just four weeks to live. Sarcoma specialists Sam Ford and Professor David Gourevitch can't be sure whether they will be able to save Jasmine until they open her up and inspect her anatomy. Such is the risk of this surgery - five years ago they would not have embarked on this intervention. Sue Sinclair, lead anaesthetist and matriarch of theatre, keeps the others in check - working alongside them as they battle to detach the tumour from Jasmine's organs and blood vessels, and remove it intact. Whenever it presses heavily on vital blood vessels, Jasmine's blood pressure plummets, placing her life in grave danger. It will take unwavering focus to keep her alive. The tumour has grown so invasively that it has crushed and displaced Jasmine's internal organs. Sam and David have a puzzle on their hands to identify what and where everything is. At times, dark humour is the only way to release the tension as they grapple with blood, guts and mind-boggling complexity.

Michael Mosley vs the Superbugs

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.
