This is the first scene from the first opera of Wagner’s Der Ring des Nibelungen epic, Das Rheingold.The rheinmaidens singing of Rheingold is just so beautiful, and its been stuck in my head for several days now. I only realized Wagner’s Ring cycle existed a couple of weeks ago, and since I have all the time in the world right now, I am slowly going through it. Its a story that has inspired so many novels and authors and the music is just incredible.
This was what I first thought of when I heard about the blasts in Boston.

What is with all the book titles that end with : (colon) A Novel? Is the extra descriptor to let people know its a novel you are reading really necessary? Once in a while, ok, its fine, but there are way to many book titles like that these days!
Scientists have injected some human glial cells into the brains of newborn mice. When the mice grew up, they were faster learners. A study, published Thursday in Cell Stem Cell, not only introduces a new tool to study the mechanisms of the human brain, it supports the hypothesis that glial cells — and not just neurons — play an important role in learning.
The researchers say these mice are measurably smarter. In classic maze tests, they learn faster. “They make many fewer errors, and it takes them less time to come to the appropriate answer,” says Steve Goldman, a neuroscientist at the University of Rochester who has studied brain cells for decades.
It might take a normal mouse four or five attempts to learn the correct route, for example. But a mouse with human brain cells could get it on the second try. Glial cells — those boring glial cells — somehow enhance learning. (NPR)
This sounds pretty shady…why didn’t the immune system just kill the cells?
Cells of Escherichia coli labeled with an amino-specific Alexa Fluor dye and examined with a fluorescence microscope. By using pulsed light (strobed laser illumination at a smaller average intensity) and an ordinary CCD camera, one can see what flagella do as swimming cells run and tumble.

Didn’t even know E. coli had flagella…
