Cancer - Hallmarks and Hit and Run Viruses

NCRI Cancer Conference (c) NCRI

We catch up with cancer research this week including evidence that cancers subvert stem cells to suppress the immune system, and how covert "hit and run" viral infections may be triggering a lot more tumours than we first thought. Also, joining us from the National Cancer Research Institute conference in Liverpool, cancer biologist Bob Weinberg explains how he sees cancer becoming a controllable chronic condition within just ten years. Plus, the buzz around a new tumour-spotting ultrasound technique, how a burst of electricity to the brain boosts mathematical ability, a new trick to block the brain damage done during a stroke and how bacteria store the genetic fingerprints of past viral adversaries to protect themselves in the future.

  • 07:05 - Cancer's Own Immunosuppressants

    New research has identified how tumours attract stem cells from around the body that are capable of suppressing the immune system - removing these cells leaves the tumour vulnerable to attack. Cambridge University's Professor Douglas Fearon explains more...

  • 13:31 - Bacterial immune system probed

    Bacteria have a clever gene-based immune system that helps them fend off attack, researchers have found...

  • 16:25 - Planet Earth Online - Supercooled Water

    Now, here’s an easy science question: What temperature does water freeze at? Zero degrees, right? Actually, that’s not necessarily the case and scientists at the University of Leeds believe that supercooled water may be implicated in the crash landing of the British Airways 7...

  • 21:56 - The Hallmarks of Cancer

    10 years ago, a seminal paper entitled “The Hallmarks of Cancer” was published in the journal Cell, examining the state of the nation in cancer research. Now, the authors - Douglas Hanahan and Robert Weinberg - are addressing the National Cancer Research Institute's Annual Conf...

  • 31:13 - Hit and Run Viruses Leave Tumours in their Wake

    Now for many years, scientists have known that viruses are the direct causes of some cancers and probably the best described example is HPV, that’s the Human Papillomavirus which is linked to cervical cancer. But recently, researchers at Cambridge University uncovered evidence ...

  • 38:53 - Naked Engineering - Ultrasound

    This week, we look into the science and engineering of ultrasound, and find out how it can be used to look for tumours...

  • 47:48 - Do research cell lines mutate?

    Dear Chris and the gang, I'm a junior member of a lab here in Cambridge and work on breast cancer. We use DNA, proteins and RNA which are isolated from immortalised breast cancer cell lines, some of which have outlived their cancer-suffering donors by decades. My question is ...

  • 49:10 - Are viruses intelligent lifeforms?

    Are viruses intelligent lifeforms?

  • 49:55 - What would the world be like if we didn't have viruses?

    Hi Chris,   I was at your talk last night in Sydney, infact I am the haggled looking lady who asked for your autograph! I do apologise for being rather spaced, I had just walked the length of Sydney to get there, had gotten lost and am pregnant. I also wanted to say what grea...

  • 50:29 - Does a mountain make the day longer?

    How many more hours of light would you get if you were sitting at the top of Mount Everest compared to someone at the same latitude, sitting at sea level?
