Snail’s love dart works like a syringe – a first, study says

When certain hermaphrodite snails — that is they are male and female at the same time — mate, they stab each other with so-called love darts. Now, for the first time, scientists have discovered a snail species with a love dart that works like an injection needle.

The syringe-like dart delivers a “gland product” to the partner snail “via channels within the dart and comes out through the holes that are present on the side of the dart,” Joris Koene, an ecologist at Vrije University in Amsterdam, explained to NBC News in an email.

For those who need a visual cue on their partner’s readiness to get it on, there’s a new high-tech garment in the offing that turns increasingly transparent as the wearer’s state of arousal heightens.

“We call it techno poetry when this relationship between technology and the human body get immersed,” Daan Roosegaarde, who heads up the Netherlands-based design firm that created the garments, told NBC News.

Robots: The gateway to ‘mind-blowing sex’?

Robotic sex won’t just blow your mind, it may curb many of society’s ills, says a new paper that envisions Amsterdam’s red light district staffed by androids that perform a full menu of sexual services.

Lap dances and intercourse with robot prostitutes could help combat human trafficking and the spread of sexually transmitted diseases while teaching us to be better lovers, according to the arguments laid out in the May issue of the journal Futures.

Skewed sex ration curbs courtship

Publication: msnbc.com   Date: May 25, 2011   View Article

When a woman walks into a male-crowded bar she’s unlikely to be showered with courtly attention — that is if findings about mating in the animal kingdom translate to the human realm.

“She might just be watching them fight it out and then have one particularly possessive one making sure others aren’t getting access to her,” Laura Weir, a postdoctoral fellow at Simon Fraser University in British Columbia, Canada, told me today.

In other words, as the dudes duke it out with each other, one little weasel will sneak over and trap her in a corner and try to keep her all to himself?

“Exactly,” she said, although she stressed her reluctance to take the analogy too far. The data, she noted, is compiled from the mating behaviors of the birds and bees … and alligators, fish, frogs, lizards and lobsters, too.

Spanish female faces getting bigger

Female faces have gotten larger in Spain over the past four centuries while those of men have stayed essentially the same, according to a new study that suggests differences in the craniofacial features of men and women have become less pronounced.

The finding is based on the comparison of more than 200 skulls dating to 20th- and 16th-century Spain, as well as approximately 50 skulls from 20th-century Portugal using a state-of-the art 3-D shape analysis system.

Mouse Tears Are Aphrodisiacs

A guy who can shed a tear really can drive females wild—among mice, at least.

According to a new study, male mouse tears contain a sex pheromone called ESP1, which makes female mice more receptive to mounting.

Good times of the animal kind

Few humans would disagree that a good chuckle every now and again feels good. Monkeys, dogs and fish get a kick out of life as well, says Jonathan Balcombe, a senior research scientist with the Physicians Committee for Responsible Medicine in Washington, D.C. He has written several research papers and books on animal pleasure, including “Exultant Ark: A Pictorial Tour of Animal Pleasures,” due out next year. Check out an overview of good times in the animal kingdom.
