Curries might control methane emissions in farm animals:
Research carried out at Newcastle University has found that coriander and turmeric – spices traditionally used to flavour curries – can reduce by up to 40 per cent the amount of methane that is produced by bacteria in a sheep’s stomach and then emitted into the atmosphere when the animal burps.
I was surprised by that last word: burps. I thought methane came out of the far end of the digestive track. It’s good news nonetheless. I think I’ll do some experimentation myself.

Don’t do your experimentation around me if you can help it.
