this month was kind of a wacky one for the network.

We are going all over the place, from extreme weather events

to extreme viral behavior, to the evolutionary psychology

behind the booming industry that is -- monster pornography.

I'm gonna throw it right over to John Horgan to explain that one first.

this is written primarily by women, for women and it involves

often, at least initially, non-consensual sex

every possible crazy entity that you can imagine.

but especially the female mind and the female libido

I mean, because who could possibly predict something as crazy as --

This month on her blog, The Artful Amoeba,

Jennifer Frazer gets us a history about a virus that has managed to

successfully invade an animal host from a plant host.

Tobacco ringspot virus normally causes trouble

in plants like soybean, raspberry, and of course, tobacco.

So it came as a shock when scientists discovered the virus

Honeybees and plants are separated by about 1.6 billion years of evolution.

So, host leap of that magnitude is mid boggling about.

The virus may have been added by a high mutation rate

and also by the fact that can be a sexually transmitted disease of plants.

Which means it can get around virus per packet, we call polen.

Since bees regularly wallow in the stuff, and do it with gusto,

the virus clearly had a motive and an opportunity.

When scientists discovered the virus comfortably ensconced

inside bee's wings, antennae, nerves and blood,

it became clear that, no matter how improbable,

We are all very aware of the crazy cold weather

that has been going on in a lot of places in North America this month.

what this polar vortex is and exactly why such cold temperatures

in such extreme storm events are happening.

every time the temperature has dropped, like it's some mystical beast

that comes down from the North Pole and grips us into a deep freeze.

Well, my blog has the details, but you can think about like this:

The polar vortex is a prevailing wind pattern that circles the Arctic,

flowing from West to East all around the entire planet.

Normally it does state far north and locks the cold air up

towards the North Pole, but occasionally the vortex weakens

and allows that cold air to drift down through Canada into U.S.

The vortex, when it does that, can also push the jet stream

so we do stay in the cold for days on in.

So, what causes the vortex to weaken, in the first place?

Well, we'll have to read the blog for the details, but here's a hint:

it has to do with a lost of arctic sea ice in the summer time.

Well, there you have it, just a small sampling

Make sure you check back to all of your favorite blogs, you know,

weekly there are so many cool histories coming in your away.

I get the highlights just of a few of them

and I will be back to do just that again in February.
