There's a sex bias in evolution, according to an article in PLoS Genetics, and it's demonstrated by the fact that women have been more successful on average in passing their genes on to the next generation. "This is because a few males have fathered children with multiple females, which occurs at the expense of other less successful males", says Dr. Michael Hammer, ARL Division of Biotechnology at the University of Arizona.

The group has found DNA evidence that polygyny, the practice among males of siring children with multiple female partners at the same time or successively, has led to an excess of genetic diversity on the X chromosome relative to the autosomes.

Plenty of sun and some ice for water sounds like a lovely place for a moon base, doesn't it?

Three-dimensional views of the mountainous terrain surrounding a “peak of eternal light” near the Moon’s south pole have been released by the European Space Agency. Dr Detlef Koschny will present the images at the European Planetary Science Congress in Münster on Friday 26th September. Images taken by the AMIE camera carried by ESA’s SMART-1 mission have been used to create digital elevation model of the peak, which is almost continuously exposed to sunlight.

“AMIE is not a stereo camera, so producing a 3-D model of the surface has been a challenge,” said Dr Koschny. “We’ve used a technique where we use the brightness of reflected light to determine the slope and, by comparing several images, put together a model that produces a shadow pattern that matches those observed by SMART-1.”

I'm obsessed with the apocalypse. No joke.

I always carry a mini-emergency kit stuffed in an Altoids tin, and I know that if the apocalypse comes, my husband and I are supposed to meet at our apartment, grab our pre-packed bags, maybe the cat, and head for the hills. 

We own a Grundig self-powered radio with hand crank and charger for cell phones with various adapters. Survival manuals. Canned food. Bottled water. Check. Check. Check.

Zombies, watch out! We're armed. Nuclear attack? No prob--we've got pills for that.

But what if the apocalypse isn't zombies? What if it's not radiation poisoning we've got to be worried about? What if it's simply some giant celestial object bearing down on us?--I'd need several pills to handle that. 

Sounds improbable? Think again.
