Scientists at California's Monterey Bay Aquarium Research Institute and the University of Rhode Island recently reported on the same-sex mating habits of Octopoteuthis deletron, a deep-sea squid that indiscriminately shoots sperm packets onto both male and female squids passing by.
It looks like your kindergarten gut reaction to kissing might have been correct after all: it really is sick. Or, more specifically, the practice is designed to spread sickness. British scientists say the human habit of kissing evolved for less-than-romantic reasons, but one that is nonetheless important to a healthy reproductive relationship: to spread germs.
A pair of MIT students claim that they have created an algorithm that outs gay members of Facebook by analyzing the sexual orientations of their networks of friends.
The students first analyzed the networks of people who publicized their sexual orientation on Facebook. Turns out that statistically speaking, gay men have more gay friends than straight guys do. So then, they used an algorithm to run the stats on men who kept mum about their sexual orientation on the site. Their computer program was able to correctly identify 10 men whom the students personally knew to be gay in the real world but who hadn't shared that fact on Facebook.
