Recently I was asked to write and perform a hand-binding wedding ceremony for two of the loveliest people I know while I was dressed as a dragon.

Eva Rushton Aug 8. Gary Brocks Aug Pictures of ethnic extermination camps, barbed write, mass graves, Happeing again. Happening despite the awareness and vows after the holocaust, that such things must never be allowed to happen again. An awareness that had grown stale.
Do the horrors of history, even in our ignorance or innocence, ultimately make even the smallest of our acts, some how complicit? Micrography-Mike D Jul This roundabout plumbing can make for some rather annoying glitches. At the elbow, for instance, an artery branch meets up with the ulnar nerve, which animates your little finger, just under the skin.
Feed a second artery into the back side of each arm and leg, by the shoulder blades or buttock, says Rui Diogo, an assistant professor of anatomy at Howard University, in Washington, DC, who studies the evolution of primate muscles. This extra pipe would provide a more direct route from the shoulder to the back of the hand, preventing vessels and nerves from wandering too close to the skin.

The photoreceptor cells in the retina of the eye are like microphones facing backward, writes Nathan Lents , an associate professor of molecular biology at the City University of New York. The setup may encourage the retina to detach from its supporting tissue—a leading cause of blindness. It also creates a blind spot where cell fibers, akin to microphone cables, converge at the optic nerve—making the brain refill the hole. The recurrent laryngeal nerve RLN plays a vital role in our ability to speak and swallow.
It feeds instructions from the brain to the muscles of the voice box, or larynx, below the vocal cords. Theoretically, the trip should be a quick one.

But during fetal development, the RLN gets entwined in a tiny lump of tissue in the neck, which descends to become blood vessels near the heart. That drop causes the nerve to loop around the aorta before traveling back up the larynx. Having this nerve in your chest makes it vulnerable during surgery—or a fist fight. While a baby is in utero, develop the RCN after sending that irksome neck lump of vessel tissue to the chest. The trachea windpipe and esophagus food pipe open into the same space, the pharynx, which extends from the nose and mouth to the larynx voice box.
To keep food out of the trachea, a leaf-shaped flap called the epiglottis reflexively covers the opening to the larynx whenever you swallow.
Take a cue from whales, whose larynx is located in their blowholes. If we moved the larynx into our nose, says German, we could have two independent tubes. But we could still communicate in song, as whales do, through vibrations in our nostrils.
