If you ever wondered about the post-coital habits of squid, today is your lucky day.

It turns out that squid are a lot like humans, except for a few minor details like their customary three-hour athletic sexual abilities.

Scientists of the University of Melbourne collected dumpling squid from the wild and forced the squid — both males and females — to swim to exhaustion in a flume.

This photo went viral last week.

It shows a young woman, probably a soldier, in a bikini, enjoying the sun on a crowded beach in Israel.

Oh, I almost forgot: she also has a machine gun slung over her shoulder.

The photo’s caption: “Only in Israel” says it all.

Because only in Israel can women play out their inner Bond girl fantasies. Even if they didn’t know they had inner Bond girl fantasies.

Take me, for example.

Last week while visiting Tel Aviv, I sat on the train next to a very attractive woman with a rifle.

It’s not that I didn’t know they had mandatory military service for both men and women in Israel, it’s just that I’ve never sat next to an armed woman in public transportation, attractive or not. It’s not the kind of thing that happens on New Jersey Transit.

I tried to play it cool.

I casually put my purse in my lap and she casually took her gun off her shoulder and put it in her lap. I removed my sunglasses, she loosened the heavy belt on her uniform.

“Military service,” she clarified.

“Vacation,” I clarified.

Funny, women have the ability to communicate surprisingly concisely in the presence of an assault weapon.

I can’t say sitting next to an armed 18-year-old woman made me nervous. I can’t even say it made me feel safer. What I felt sitting next to the alpha female — in my pastel-colored summer dress and heels — was pure, distilled inferiority. Mercifully, she wasn’t wearing a bikini.

What is it about guns and bikinis, anyway? What happened to the idea that men are biologically predisposed to desiring to protect the weaker sex? Why the fascination with armed women?

According to Allison Kaplan Sommer, who wrote a blog on Haaretz.com about the “hot Israel chick with gun,” it‘s not the bikini. Neither is it the gun. It‘s the combination of the two.

Clearly, Angelina Jolie and Megan Fox have had it right all along.

This is what Sommer wrote on Haaretz:

It’s been another fruitful year of vaginal evolution.

In the last few years female genitals have arguably gone through more transformation than in the previous million years.

Pubic hair has become, more or less, extinct.

Labiaplasties — mainly those to decrease the size of the labia — have gone mainstream.

But as vaginas "improved," it became obvious they are just not perfect enough.

Enter vaginal brightening.

Welcome to 2012, the year pink vaginas became the thing to have.

I haven’t quite noticed the tipping point in the acceptable coloring of female genitals, but as far as I can tell, it all happened quite gradually.

I am not going to be boring and blame pornography, although I have no doubt porn has affected the way we view — and compare — genitals.

Let’s not forget it was porn — and Sasha Baron Cohen's Bruno, of course — that made anal bleaching a household term a few years ago.

Nowadays, some salons pitch the procedure as a “part of personal hygiene.” Kind of like Brazilian waxing.

Which brings me back to vaginal brightening.

Earlier this year, scientists shook the planet by revealing men prefer pink vaginas over red ones.

All this time, we were being told that red is the sexiest of colors, being fed images of women clad in red lingerie, red lipstick and a red dresses. What we didn’t know is that while red might be the sexiest of colors, its charm doesn’t necessarily apply to female genitals.

When it comes to vaginas — or, to be technically precise, vulvas — men apparently prefer pink shades, not red ones.

That, in a nutshell, is the finding of a study lead by researcher Sarah Johns, anthropologist at the University of Kent, and http://www.plosone.org/article/info:doi/10.1371/journal.pone.0034669 ">published in the April 6 in the journal PLoS ONE.

The researchers asked 40 heterosexual men to look at 16 images of female genitals in random order and rank them on a 0-to-100 scale of attractiveness.

The results showed that instead of preferring red, perhaps as a sign of fertility (think baboon bottoms), men actually liked pink vulvas the best.

Johns is quoted in LiveScience: 

Here's another one for the “myth of monogamy” file.

For a long time, ornithologists believed that most birds were monogamous.

According to this article in Acorn, ornithologist David Lack estimates that at least 90 percent of nest-raised birds come from monogamous pairs. 

Monogamous birds such as eagles and geese were long regarded as the epitome of fidelity and social monogamy, remaining together until one dies.

According to Acorn, Canadian geese are among the most faithful birds, mating for as long as 20 years.

But based on new DNA testing of several bird species, it turns out that even monogamous birds are not as loyal as previously thought.

They, too, tend to have flings on the side.
