10:49a - Feeling good
SO, despite the whole, "I don't have a car" thing right now, I actaully feel pretty darn good. I have had an awesome morning.
I walked Cam to school, he threw a fit to go into the building and tried to leave with me, but they showed him books and he was just fine afterwards. I watched from the window, it was so cute.... We're doing something right if at the age of four he already loves books....
I walked, ran home. So I am not in perfect condition, I was also not wearing a supportive bra, ouch! but I did learn it only takes me twenty minutes to walk to Cam's school and I can do it a little faster when I am not dragging him in his cart.
I then got the courage to mow the back lawn. I broke the last lawn mower doing this a couple of weeks ago, but it really does need to be done and I am the only one who really has the time to do it. I did succeed without killing myself or the mower and I rammed down some silly plants/baby trees that the landlord had cut down last year.
I then clipped the front hedge with my new Cutco kitchen shears. These baby's will cut through a penny, it's fun to do!
Then I came in had breakfast and learned how to creat folders on the desktop and how to transfer pics from my memory card to my new folders. I feel I have had a darn good morning.
NOw to go get CAm from school. darn!

12:57p - weird thing of the day

Geckos that forego sex and instead clone themselves are able to run farther and faster than relatives that reproduce the more conventional way.
"This is extraordinary," said Kellar Autumn from Lewis & Clark College in Oregon. "The traditional theory is that when a species gives up sex and reproduces through cloning, the offspring will have reduced performance."
Parthenogenetic animals, which create exact copies of themselves, are all females: mothers cloning daughters. Autumn and colleagues studied the parthogenetic Bynoe’s gecko from Australia.
Run, Gecko, Run!

The researchers used a state-of-the-art lizard treadmill to test the gecko’s speed, body temperature, and calorie burning, and compared them to other lizards.
The Bynoe’s geckos turned out to be much better athletes than their sexually reproductive relatives, outperforming them by 50 percent on the treadmill. This was a surprise, since a similar study of lizards from the deserts of the United States had shown the opposite trend.
One of Autumn’s coauthors, Michael Kearney, said that some parthogenetic species, like the Bynoe’s gecko, evolved when two species crossed, or hybridized. Kearney compared these ultra-fit geckos to the "super tough" mule, which is a cross between a horse and a donkey.
"If there was an Olympic team of Bynoe’s geckos, there wouldn’t be a single male on it," Autumn said. "They are the ‘Xena: Warrior Princess’ of the lizard world."
The findings are in the May/June issue of the journal Physiological and Biochemical Zoology.
