That's all they are. Not fate, just probabilities. <a href="http://www.laurenweinstein.com/">Lauren Weinstein</a>, cartoonist, is having a baby, and she's told — out of the blue — that she and her husband are both carriers of the gene that causes cystic fibrosis. They are sent to a genetic counselor. What happens next — told in five beautifully drawn, emotionally eloquent cartoons — tells what it's like to walk the edge for a few weeks. She's so many things (sad, funny, scared, puzzled), and then there's the ender.

On to lunch!<p>This is the story of a bird, a puzzle, and a painting. The painting, curiously, helped solve the puzzle, which is: How do vultures find food?<p>In America, back in the 1820s, everybody knew the answer. Vultures are scavengers. They eat dead things.

How come there are kangaroos in Australia, and none in southern Africa --which seems, environmentally, very kangaroo-friendly? Certain frogs show up in warm ponds in one part of the world, but warm ponds a thousand miles away have none. Why?<p>Scientists in the 1930s hadn't yet come up with the notion of plate tectonics (that continents break up and move, carrying animals with them).

As in names for themselves? Names for each other? I've always thought that what we do when we call ourselves "Ralph" or "Laura" is unique, something exclusively human. But it turns out that's wrong. Other animals have name-like calls that they use much like we do.

Why Life Is Unfair http://iowapublicradio.org/post/jupiters-dot-and-mine-why-life-unfair When I was 9, my dad drew this picture of me. You will notice something on my left cheek — a little brown spot.<p>That's a mole. The doctor called it "a birthmark." My mom called it "a beauty mark." I was born with it. Having grown up before supermodel Cindy Crawford became famous, I was not familiar with the allure of beauty marks and, anyway, I'm a guy. My mom said it was hardly noticeable. I didn't believe her.<p>It didn't go away. Worse, in my mind it was growing bigger. In grade school, I worried that the mark on my cheek was the first thing people saw when they looked at me.
