Republicans teabagging Obama

Ok, they DO know what teabagging means in this video clip, but what are the Republicans thinking (R-rated definition, likely to offend: Urban Dictionary: teabagging)

Mitochondrion ar cool.

Mitochondria are just the coolest thing, imho.

Mitochondria have many features in common with prokaryotes. As a result, they are believed to be originally derived from endosymbiotic prokaryotes…. The endosymbiotic relationship of mitochondria with their host cells was popularized by Lynn Margulis. The endosymbiotic hypothesis suggests that mitochondria descended from bacteria that somehow survived endocytosis by another cell, and became incorporated into the cytoplasm. The ability of these bacteria to conduct respiration in host cells that had relied on glycolysis and fermentation would have provided a considerable evolutionary advantage. In a similar manner, host cells with symbiotic bacteria capable of photosynthesis would also have had an advantage. The incorporation of symbiotes would have increased the number of environments in which the cells could survive. This symbiotic relationship probably developed 1.7-2 billion years ago.

Recycling around earthday.

This is a cute video by Sarah/Girltarist, who is, among other things, a student in my and Danny’s classes. We had a chat about reducing and reusing being better than recycling, but one thing at a time. I wish more educators would sing and share their songs.

The first web server

Chatting with Nick about various things such as Bell Labs, Xerox Parc, and we got onto the notion of the World Wide Web. And I found this picture of the first web server. Of course I knew it was a NeXt cube, but I’d never SEEEN it.
