1-in recent years, a number of research projects have been carried out to investigate how man’s best friend, the dog, earned this title. It was reported by researchers quite some time ago that all dogs, from tiny Chihuahua to very large great dance, are the domesticated descendants of wolves. Scientists, however, are still in the dark about exactly when dogs stopped being bloodthirsty wild animals and started to get along humans, even earning the title of ‘man’s best friend’
2-Did you know that if aspirin didn’t exist today, people would probably still trying to treat fever with willow tree compounds? That’s Wright! In 400 BC Hippocrates, the great physician regarded as the father of medicine, recommended a tea made from willow leaves for the treatment of fevers, aches and pains. Years later, scientists discovered that it was salicylic acid a substance found in willow trees which actually relived pain and reduced fever. Aspirin was perfected in 1879. Nowadays, aspirin is the most widely used painkiller in the world; 100 billion doses are consumed each year.
