Logged on the BBC Science Website. There were a couple of stories that really interested me:

1. Dogs Also Display Jealousy
Scientists in California tested 36 dogs by getting their owners to pay more attention to a realistic looking stuffed dog than to them. Over three quarters of the dogs were likely to push or touch the owner when they interacted with the decoy. However, the dogs were more than three times as likely to do this when the owner interacted with the 'dog' than, say, a book.
Around a third tried to get between the owner and the stuffed dog, while a quarter snapped at the intrusive toy.
Christine Harris from University of California in San Diego suggested not only that dogs do engage in what appear to be jealous behaviours but also that they were seeking to break up the connection between the owner and a seeming rival.
Before, jealousy was thought to require a complex cognition and is unique to people, however, this study proved that jealousy is also hard-wired into dog's brains.

2. The Stress Test
Some scientists were curious to find out the correlation between biological, social, circumstantial and psychological factors and how exactly these influence stress in a person. To do this they launched a survey which more than 30,000 people completed.
WHAT DID THEY FIND?
They anticipated that a family history of mental health issues, social deprivation and traumatic or abusive life experiences were more likely to lead to higher levels of anxiety, and were proved right.
However they discovered that a person's psychological functioning also played an important role - specifically, wether they were able to cope with life's difficulties (known as 'adaptive coping'), how much they dwelled on their problems (known as 'rumination') and how much they blamed themselves.
The results suggested  that psychological factors play a mediating role in a person's amount of anxiety and stress.
