More Armpit Sweat 

We learned last week that sniffing your coworkers' armpits may be a good way to decrease stress at work, but were left wondering why. Well, a Berkeley study has found that a male pheromone, androstadienone, secreted in sweat, caused exposed heterosexual womens' cortisol levels to become elevated. And they got turned on. So, it seems that maybe too much antiperspirant may not be a great idea.

Speaking of taking the romance out of things, US researchers have found that insecure babies grow up to have relationship troubles. What makes a baby insecure? Since no one knows precisely, we stick with the default: blame your parents!!!

You can blame everything on your parents, you know. After all, they gave you your genes. They may have given you a mutated SLC30A8 zinc transporter, increasing your risk of type 2 diabetes, or they gave you a common version of DARPP-32, which makes you a better thinker (by improving communication between the striatum and PFC) but may also put you at risk for schizophrenia (if the cortex is otherwise compromised and can't handle all that striatal input).

And finally, genes aside, your brain needs sleep. Mouse studies indicate that sleep deprivation inhibits hippocampal neurogenesis, and while we're not sure exactly what those new cells are needed for, it's probably a safe bet that their lack is related to the cognitive deficits seen in sleep deprivation.
