How Cancers Form, Cancer Biology and Future Therapies


Phil Rosenberg

Chris Smith

Cancer biology goes under the microscope this week, as Professor Gerard Evan from the University of California San Francisco talks about the causes of cancer and how cancer spreads around the body. Also on the show, and joining us live from the National Cancer Research Institute Conference, is Professor Fran Balkwill from Queen Mary's School of Medicine and Dentistry, who will be discussing cancer treatments and the development of targeted therapies, and Dr Kat Arney, who will be talking about the latest news in cancer research. We also travel Stateside for a Science Update from Bob and Chelsea, hear from Dr Michael Halpern from the Union of Concerned Scientists about governments interfering with scientific research, and experience the deep freeze with a couple of balloons and some liquid nitrogen in Kitchen Science.

Winners of The Ig Nobels

In a parody of the real Nobel Prize Awards the Ig Nobel Prizes are awarded for scientific achievements that make you laugh, then think. Ten awards were passed out this Thursday and this is my highlight. Francis Fesmire of the University of Tennessee College of...

 

Allergy Cure Not To Be Sniffed At

A Swiss company - Cytos Biotechnology - have produced a vaccine which they say can neutralise allergy symptoms for at least 8 months. Ironically it works by fooling the body into thinking that it is suffering from a bacterial infection. Known as CYT003-QbG10, ...

 

'Good Bacteria' Fight Off HIV

Scientists have engineered one of the "good bacteria" naturally found colonising the human female genital tract to enable it to produce a chemical called cyanovirin-N, which has powerful anti-HIV effects. Just as some people take probiotic yoghurts as an...

Experimenting with gases and liquid nitrogen

This week Derek is with Dr Chris Muirhead from Birmingham University and student volunteer Mary from Hills Road Sixth Form College in Cambridge. They'll be using liquid nitrogen, which is very cold and can be very dangerous. Chris has special liquid nitrogen safety training, and you should NOT do th...


Questions

 

I'm researching the 21 grams postulate from 1907. What can you tell me about it or refer me to in order to prove or disprove this urban myth?


 

I've just been reading Superhuman by Robert Winston this week and never realised that mitochondria, the power houses of our cells, produce the majority of free radicals in our body.


 

If radiation is so dangerous to cells, why don't they use it more for brain tumours?


 

Upon-Tyne - My mum is currently having chemotherapy and radiotherapy. What makes her hair fall out, and is radiotherapy worse if it's directed at one point in the body only?


 

I'm 24 and I was diagnosed with bladder cancer earlier this year. How did this happen? I'm only 24?


 

Gerard said earlier that all cells want to expand and grow and live. So why does cancer kill you? Why don't you just end up as some massive big cancerous blob that lives forever rather than die?


 

A while ago I was in an experiment where we were told that some people's blood fights cancer. Her idea was that once you've had an operation for cancer, you then have a blood transfusion with this blood for cancer to sort of mop up any bits that they missed. Is that still going on?


 

How are stem cells being used in cancer research?


 

I'm an A-level biology student and I'm interested in knowing how mRNA from a gene gets from the gene in the nucleus out to the right place in the cytoplasm where the protein is made.
