I don't want to sound alarmist, but glow-in-the-dark animals are real-- and it's not just cute kitty-cats.  As reported earlier here at Science 2.0, scientists did this and that to genetics to make AIDS-resistant cats.  Part of the process includes splicing in jellyfish DNA so the cats glow in the dark.

Yes, not 'they glow because of the medical reason', they glow for the fun of it.  They glow because the scientists wanted to track the progress of the other stuff, the real medical stuff they were doing.

In Physics Today's 'We love you, you're perfect, now edit', three editors give advice to potential science writers.  Their advice includes the 3 holy rules:

  1) know who you are writing for
  2) meet your deadlines
  3) be polite

... and expands on it a bit.  Am I to steal another's writing instead?  No, so go read the piece.  That's what links are for.

Do you know what a creepmeter measures?  Measurement is the heart of science.  What distinguishes science from opinion or philosophy is measureables.  The root of science is facts that are determined by actual observation, compared, then extended into predictions.

Any good measurement has three parts: the number value, the units you're using, and the error.  If I say I am 6 feet tall, that's a number (6) and a unit (feet), with a presumed error of 'within an inch or two'.  All three parts are crucial.

I think it's heartening that people are starting to talk about careers for PhDs past Academia.
