I'm on a roll this week. I've been banging my head against a piece of code the past couple of days—until four o'clock Thurs, when my officemate and I went down for tea. One coffee and a Cornetto™ later, back at my desk, I nailed the bug. And I've just got back from a curry in London with a couple of old lab mates. One of them is going to set her research assistant onto an experiment I suggested as soon as she moves to her new lab in Sweden.

In other science news, monkey walks like human, Stephen Hawking admits he was wrong about black holes, and Mars found at South Pole.

[Reader, stick with the Hawking story to the very end, especially if you are Judith. You'll be amused to read what was at stake in Hawking's bet with his fellow physicist.]
