Parachuting Aquatic Snails

2011-10-08_14-00-54_221

Michelle, one of my dearest childhood friends and I had a sleep over last night. True to a 25 year long trend. We stayed up too late pouring over children's books and listening to silly songs. This morning we baked oatmeal chocolate chip cookies for breakfast and played with watercolors at the kitchen table. The main difference between now and then seems to be that now we play on an iPad and have unsupervised use of the oven.

Murphy the Dragon

2011-10-07_18-28-18_794

Murphy, todays featured dragon, spent his morning basking on a mound, enjoying the sunshine after a few rainy days. In the afternoon he walked into his sunroom for a nice view of some tourists, and after a quick walk through his yard for a photo op, he ate three yummy rats for dinner. After dinner he blew spit bubbles in his drool then went for a swim.

This behavior is remarkable because since he is used to being handled in the morning and fed in the afternoon, his vet was able to give him an x-ray one morning without sedating or restraining him.

Named after curator, Jim Murphy, he was born to the Miami Metro Zoo on 10/12/98. The last measurements record him as 8 ft long and 130 lbs.

Beaded Stethoscope

2011-10-06_17-57-19_007

 

I am exploring the National Library of Medicine in my free hour between friend visits today. I just had coffee with my friend, Mark, at AFRRI and right across the street is NIH. In the exhibit that opened yesterday, Native Voices: Native Peoples’ Concepts of Health and Illness, I found this beaded stethoscope.

The sign next to the stethoscope reads: 
“The beaded stethoscope symbolizes the integration of the traditional and Western medicine at the Native American Health Center, Oakland, CA. The four colors of the beads – red, yellow, white, black – are symbolic of the Medicine Wheel, that highlights a holistic approach to health and healing used by the Native American Health Center.”

Happy the Fish

2011-10-06_09-23-53_093

I'm visiting my friend Julia in Virginia. While we cooked raspberry pancakes and scrambled eggs for dinner, her fish, Happy, kept us company. He's very attentive and swims over and watches us while we cook. His little fish bowl with blue glass marbles sits on the counter of the breakfast bar, giving him an excellent vantage point for observing mammal feeding behavior.

NP-Hard Family Logistitcs

2011-09-22_23-03-27_516

So I called my mom and brother two weeks ago to try to get my family together for dinner. Planning time to see my family is like the late stages of the game Rummikub. You know, the part where you get to completely rearrange the board to try to fit in one more piece?

Each person gets a chance to rearrange everything each iteration, and if it doesn't work out they can't always put it back the way it was when they started. Arthur believes this to be equivalent to the Merkel-Napsack Problem, is NP-Hard and that a non-parallel computer can't solve this efficiently. Who needs made-up games like Sudoku when you get to play the family logistics game? So when I say that I had dinner with my family on Monday night, which including my two cousins in Baltimore makes it a six person game, it's a pretty amazing feat.

Frog on a Lily Pad

2011-09-28_16-03-43_962

Mom and I went exploring at the National Wildlife Visitor Center. Alongside the bank of Lake Redington we found perched on a lily pad a tiny brown frog. In the water there was a sea of floating lily pads, a scattering of them had glassy droplets of water on the surface. As we sat and visited our new little frog friend, a spider larger than he was walked over and joined him.

We walked into the forest for a while. The air is hot, sticky and smells like decomposing leaves and mushroom spores. There are colorful mushrooms on fallen logs and sprouting like fireworks out of the ground. As we came to a grassy field, black field crickets (Gryllus pennsylvanicus) hopped out of our way with each step we took. Dramkon would love it here! Its hot and full of yummy crickets to eat! I can see adult crickets 3cm long (5cm long if you include the ovipositor) chewing on a dried flower stalk. 

As we walked back to the visitor center we stopped again to visit our little brown frog friend and found that instead of crickets hopping in the grass there were lots more tiny frogs! I counted at least six of them and they were each a new color pattern, ranging from mocha and speckled to a mossy green.
