Online Cortex Thoughts on Science and Technology

Over time, I have collected a variety of domain names… mostly as an experiment on how selling domains works.

I have found that Sedo.com is a great place to sell them.
I currently have the following for sale:

These three should go together in one portfolio focused on Asian business / investing / marketing opportunities:

asian-opportunities.com
asian-opportunities.net
china-opportunities.net

Asia is growing fast!

This one I imagine could be a site on politics… focused on people who aren’t focused on politics:
politics4idiots.com, maybe focused on the politicians themselves?

This site could be focused on stupid fun and games:
submoron.com, who doesn’t love a little mindless recreation now and again?

With the American economy suffering, I know a lot of people are selling their precious metals:
sellyourmetal.com, such as gold and silver.

and to explain to my wife how this all works, we purchased:

gourmetbooze.com - the name says it all gourmet booze, liquor and alcohol of all forms.
extremecoupon.com - everyone looks for coupons on the web!  If you dont, you should.
Its easy to get good coupons, and great coupons are even harder to find.  But extreme coupons!  WOW!!!

 We’ll see how they do!

The Quetzalcoatlus is a giant pterosaur from the late Cretaceous Period with a 30 foot wingspan… the size of a small airplane.  Many of the smaller pterosaurs, which populated the edges of the Western Interior Seaway of North America of old (now the Great Plains region), probably ate fish like modern gulls and pelicans.  But it is not clear how the Quetzalcoatlus behaved.  Their neck was probably too long and unwieldy to fish like gulls and pelicans, but it has been suggested that they might have behaved like skimmers skimming the water for their prey.  Other ideas have included scavanging like vultures.

In a recent New Scientist article, Mark Witton and Darren Naish of the University of Portsmouth, UK, found that this group of pterosaurs ”lacked all 30 specialised adaptations for skimming seen in the head and neck of the modern avian skimmer”.

Instead they suggest that the stiff neck of the Quetzalcoatlus and their great height (15 feet… taller than a giraffe) would work well for hunting small prey on the ground or in shallow water much like herons or storks.  Since Quetzalcoatlus fossils are found in inland regions, they reason that these animals probably behaved like Maribou Storks (more links to images here), which inhabit the dry savannahs of Africa and eat just about anything (dead or alive) that they can get their beaks on.

Two great images from the HiRISE camera!

This is the Phoenix probe parachuting into Mars’ north polar region from orbit with Heimdall Crater in the background.  A larger image can be seen at Astronomy Picture of the Day.

This image shows the Phoenix probe on the ground.

At this point, a camera under Phoenix may have found a hard icy substrate underlying the topsoil (story here).
