Not bad.<p>Here's another notion, this one from <a href="http://www.ricardosolisart.com/">Ricardo Solis</a>, an artist working in Guadalajara, Mexico.

Not yet a doctor, there are moments, many moments when she has the eyes of a patient. She gets scared. She feels helpless. She's too involved.

Who's On It? I Can't Believe What I'm Seeing: A Springtime (Froggy) Miracle http://wlrn.org/post/i-cant-believe-what-im-seeing-springtime-froggy-miracle Two weeks ago this animal was frozen solid. If you found one in the woods, packed in the topsoil, hiding under a leaf, you could pull it from the ground and it would feel like an ashtray. You could bang it (lightly) on a table — it would go, "Konk!" like a rock. It doesn't seem to be breathing. It reacts to nothing. It's so dead. Or seems to be. And then, this (I want to call it a miracle) happens ...<p>I did this piece when I was host of <em>Nova Science Now,</em> on PBS, and <a href="http://www.pbs.org/wgbh/nova/nature/costanzo-cryobiology.html">the mystery</a> of it still amazes me.

Is This A Trick Question? Am I Going To Die This Year? A Mathematical Puzzle http://wlrn.org/post/am-i-going-die-year-mathematical-puzzle A few years ago, physicist <a href="http://www.physics.umn.edu/people/bskinner.html">Brian Skinner</a><strong> </strong>asked himself: What are the odds I will die in the next year? He was 25. What got him wondering about this, I have no idea, but, hey, it's something everybody asks. When I can't wedge my dental floss between my two front teeth, I ask it, too. So Brian looked up the answer — there are tables for this kind of thing<strong> — </strong>and what he discovered is interesting. Very interesting.

It's called a <a href="http://planaria.stowers.org/index.php">planarian</a>. It's about an inch long, and you'll find it gliding along the bottoms of rivers and ponds all over the world. It's very flat, like a moving bit of pasta — nothing special to look at, but it has a hidden talent that has made it famous. It can regrow its body parts better than almost any other animal on Earth.

Badly http://wlrn.org/post/what-chickadees-have-i-want-badly First I look in my right coat pocket. Nothing. Then my left. Nothing. Then my pants, right side — no. Then my pants, left side — yes! This is me at my front door, looking for my keys. Every day.<p>I have this extraordinary ability to <em>not</em> remember where my keys are. It's uncanny. Every morning, I lock the front door, step away, fall into a 2 ½ second trance during which I place my keys in lord-knows-which pocket, <em>even if a second earlier I was saying to myself, "OK, remember where you put your keys." </em>But I don't. Which is why, around this time of year, I envy chickadees. Mon, 23 Dec 2013 18:25:00 +0000 Robert Krulwich 25547 at http://wlrn.org What Chickadees Have That I Want. Badly
