Nuclear Power


Kat Arney

Chris Smith

Nuclear energy is always in the news, but how much do you know about nuclear fission and what happens to nuclear waste? To find out, Naked Scientists Anna Lacey and Dave Ansell visit Sizewell B power station in Suffolk, and studio guest Ian Farnan from Cambridge University discusses nuclear waste disposal and why current methods might not contain the radiation as long as we thought. But as clinical radiologist Anant Krishnan explains, radiation plays a crucial role in medicine, including allowing us to see broken bones and killing off tumours. Sticking with uses of radiation that save lives, Anna and Dave find out how a smoke detector works in Kitchen Science.

Anti-Cancer Asprin

The humble aspirin is a bit of a wonder-drug. Not only can it cure aches and pains, but some research has shown that it might help to prevent certain types of cancer, including bowel cancer. Now Cancer Research UK has opened a clinical trial to test whether the dr...

 

Tongue to Talk About

Scientists have found the animal with the world's most powerful tongue. It's not a whale, an elephant or even a cow, it's the giant palm salamander, Bolitoglossa dofleini, which lives on the forest floors of Central America and whose tongue packs an 18 kilowatt pe...

 

Proteins Produce Prematurity

Research presented at a scientific conference in the US has suggested a way that protein analysis could be used to predict premature births. The researchers have been studying inflammatory proteins found in amniotic fluid, the liquid that surrounds a baby in the womb. Signs of inflammation are ...

 

Storm Clouds Gathering on Climate Change Horizon

If you can't take the heat you move into the shade, right? But what about if that means the entire Earth? Well that's the strategy being put forward on a planetary scale by Iowa State University researcher Curtis Struck, who suggests that one way to cool an overheated-Earth would be to mine dust fro...

How a Smoke Detector Works

Most people think radiation is a bad thing, but if you take a look inside a humble smoke detector, you'll find that it's radiation that's keeping us alive. However, you should NOT attempt to open the radioactive compartment of a smoke detector as close-up exposure to the radiation could be dangerous...

Anat is a radiologist and uses radiation to help cure disease


Questions

 

My husband is colour blind and we recently had a baby girl. I know that colour blindness is an X-linked recessive trait and that one X-chromosome is randomly switched off in females because females have two X-chromosomes and only need one. Does this mean that our daughter, as a carrier, could be colour blind in one eye or in some of her cone cells but not all of them?


 

When you're trying to go to sleep at night, why does your body jump and start twitching when you're about to drop off to sleep?


 

Why is it that car front windscreens appear more prone to icing than the sides and the rear? This is even when the car is parked either way round in relation to the prevailing wind, I think.


 

What's the smallest thing you can detect in the body with an MRI or a CT scan? Is it 10 millimetres or smaller? What's the smallest tumour you can pick up?


 

How does something like radiotherapy treat prostate cancer?
