Why so skeptical?

In a few years time, there may well be no rhinos left alive. And when I say no rhinos, I do not mean “none left in the wild”. I mean none in the zoos either. The captive animals will have been killed too. The reason for this is an insatiable desire among some people for rhinoceros horn – a material thought by some to possess magical healing powers. It’s really just a mass of keratin – the same substance that your hair and fingernails is made from. …

This is what you get when critical thinking is left to one side and blind belief trumps patient scientific inquiry. Where unsupported and uncontested beliefs thrive, dreadful scenarios can play themselves out, right down to the last animal standing.

The Placebo Effect

Via The Cork Skeptics who showed this video at their last meeting when Rebecca O’Neill talked about being a health food shop worker. (Audio of the talk here, Colm’s going to love all the pingbacks!)

What is radiation?

Here’s the first part of an excellent talk given by Professor John McInerney, of the UCC Physics Department on what exactly radiation is, the different types, the effects they have on the human body and what creates it. Do you know where most radiation comes from? You might be surprised.

Early in the talk, John dispelled with the idea of non-ionising radiation being responsible for detrimental health effects. ”Microwaves in general are not harmful, including the ones in cell-phones and radars. Unless you cook yourself. If you stood in front of a 10KW radio antenna it would be bad for you. It would serve you right. That’s Darwin’s principle at work”.

The video was filmed at a Cork Skeptics session in Blackrock Castle last May. The second part of the talk goes into nuclear power and you can watch it above.
