Sociological studies have found that middle managers tend to be more stressed than either their bosses or their underlings. That phenomenon might well be true of all primates, as macaques display heightened stress levels when they are in the middle of their social hierarchy.
There are two hormones, oxytocin and vasopressin, that generally make us more sociable, more caring, and just generally nicer. But now scientists have taken this a step further by finding the specific genetic receptors that make these hormones so effective.
Oxytocin is a hormone found to be crucial in the formation of loving bonds between mothers and babies, and it's thought to just generally makes people feel more sympathetic and connected to each other. That's definitely true of rhesus monkeys.
If you're tying to figure out how cute a baby is, you had better ask a premenopausal woman: they're scientifically proven to have the highest cuteness sensitivity. Yes, this experiment involved coming up with an objective scale of baby cuteness.
Many animals sacrifice for the sake of their children, but red crossbills are on another level entirely. Crossbills with kids have dangerously low stress hormone levels compared to their childless couples...all to make sure they don't suddenly abandon their nest.
It's not always easy to distinguish between human social interactions and the complex chemical interactions that underpin them. Just hearing a calming, familiar voice can alter a person's hormones in a beneficial way...and technology just gets in the way.
The wider a man's face is, the more likely he is to deceive others and cheat to get ahead...or so a new study claims. Is this just the new phrenology, or could there be something to the idea?
Voting isn't generally seen as the most enjoyable activity, but this is really taking things to a whole new level: voting actually causes a significant increase in the levels of cortisol, a hormone the body uses to deal with stress.
