Dogs are man's best friend thanks to bonding hormone, research shows

Guardian Science - Thu, 2015-04-16 19:00

Scientists have found that dogs and owners experience surges in oxytocin, a hormone responsible for maternal caring, when they look into each other’s eyes

A rush of hormone that helps people bond could explain why humans and dogs have been best friends for thousands of years, say researchers in Japan.

The scientists found that dog owners experienced a surge of oxytocin when their pets gazed into their eyes, a dramatic effect that was mirrored in the animals themselves.

Fundraising? Find a generous male friend and smile, says study

Guardian Science - Thu, 2015-04-16 17:19

Analysis of fundraising pages shows men are competitively generous: a big donation early on, helped by an attractive picture, can be key to success

When fundraising for charity, picking a cause close to people’s hearts and subjecting yourself to a sufficiently gruelling physical ordeal might help, but scientists suggest there could be an even easier way to swell the coffers. Picking a flattering photo and persuading a male friend or relative to make a hefty donation to your fundraising page early was found to significantly boost donations - for women at least.

A study of fundraising pages from the 2014 London Marathon showed that men become competitively generous when they see another man has already given a large sum of money. The effect was especially striking when men stood to impress an attractive female, the study revealed. In these circumstances, men quadrupled their average donations from £10 to £40 when another man had already pledged a large sum.
