Why do we get old ? Some animals can seem to live forever 200, 300 even 400 years. Various theories in biology have been put forward regarding ageing. We look at some of them in this article.
This topic of this article is born out of pain and suffering, quite literally I’m afraid. Why do Mozzie bites itch so much ?. How can something so small cause so much misery ?
Do you really need your Brain ? : WHAT !? … A joke surely. No, this is a serious question (sort of). To see why we might ask it though we need to look at a rather strange phenomenon first observed in the 1980s.
Doctor Doolittle may have been able to talk to the animals but what about plants ? Prince Charles is famous for his chatty behaviour towards his plant friends but, do plants ‘talk’ to each other ?
This is one of those mysteries that refuse to lie down (if you’ll pardon the pun). It’s also one of those questions where there’s much debate and no clear answer. However there are some good theories that are interesting to chew over.
