We’ve all secretly wondered if Rover loved us for the patting and the praise or if he was just after that juicy bone we keep in the fridge. Since Pavlov first started tinkering around in the canine brain there’s been a group of neuroscientist at Emory University in Atlanta, Georgia, who have pretty much been hell bent on working out what goes on behind their furry craniums. The question du jour is do dogs prefer praise or a hot dinner?
You would be hard pressed to meet someone who has not been affected by breast cancer either personally or through association. It’s an insidious disease that is ranked second in all new cancer cases worldwide. It is the leading cause of cancer death in women. And it’s showing no sign of abating. Instead it’s been growing by 2% a year.
You only have to ask someone like Jerry Maguire, driving his car, flicking through the radio stations searching for just the right song, how important music is. Music when it hits that sweet spot makes your foot tap and your heart sing. It makes you want to jump up and dance, or sing loudly out of tune. Music can bring out the depths of your sadness and trigger long lost memories. It can make you laugh or it can touch your soul. Music has been prevalent in all human cultures since we first started scratching flint together to make flames. But music, unlike other biological advantages is not associated with advancement of our species or of our survival. That is, it’s not like food or water or sex or shelter. And it doesn’t have any utility value such as money. But music ranks as one of human beings greatest sources of pleasure. Because of this there has been an assumption that the pleasure gained from music is universal. And is therefore experienced by all humans. But it’s not.
Why is there a biological preference towards using sex as a method to reproduce...science has been studying why. If asexual reproduction is a more efficient method of continuing the species why have men and women? Turns out without both, we’re in a lot of trouble keeping genetic diversity alive and well.
