Recent research has shown that the more profiles online daters consider the less likely they are to find suitable partners. It's as if they're bamboozled by the sheer variety on offer.

Research has revealed the powerful influence of genetics on the nature of sexual attraction. With this in mind, a couple of new dating servces are offering genetically tailored matchmaking.

Many of the big paid dating sites use complex, scientific matchmaking criteria that they say lead to a higher success rate. But as this article describes, these claims can often be exaggerated.

Every now and then there is a burst of stories in the media about drink spiking in pubs and clubs throughout Australia. They paint a picture of countless predatory men determined to get young women intoxicated by stealth so they can take advantage of them sexually. Young women are warned to be vigilant, and keep an eye on their drinks (and those of their girlfriends) at all times.

Yet it seems that fear of this occurring is largely unfounded. A recent study conducted in Western Australia concludes that it hardly occurs at all. The excessive intoxication experienced by young women is usually due to their own drinking and drug taking, it seems.

Kissing is sometimes called "swapping spit". That's a fairly unromantic way to describe it, to say the least. But it turns out to be pretty accurate!

The kissers are finding out vital information about each other's DNA through the contents of their saliva. If the clues they are seeking cannot be detected after the first long pash, that can spell the end of the relationship.

Every now and then a story comes up in the media about how love is overwhelmingly biochemical, and that it won't be long before a scientifically proven "love potion" is developed.

Another one of these stories has just surfaced. Apparently there's been a lot of research into one particular hormone, oxytocin. This seems to be the key, and Australian researches are testing whether it can be used to help ease discord between married couples.

Sounds like the much anticipated "love drug" really is on the verge of creation this time.

Online dating has proven to be so effective and popular that even animals are doing it!

Well, not quite - but almost: Now zoos are using online resources to play matchmaker with animals in their various breeding programs.
