I've been trying some of these at thinks.com... ouch ouch ouch. If anyone knows a site with some beginner-level puzzles, I'd appreciate it. :)
Anyway, this one stumped me: React badly when embraced by one scientist or another (14) -- the answer is BACTERIOLOGIST... the definition makes sense, and I understand 'react badly', but how does the rest of it fit?

Oh... I get it now. d'oh.

Answer: CHUCK OUT (or at least, -H-C- OUT). But why?

The OED's 5th definition of "chuck" is food. And if you're 'out' you might have made an error, I guess.

Chuck = 'throw': Out = 'away': 'Chuck = 'food'(e.g. chuck wagon): Out = 'error' (e.g. misalignment) - Looks like a double bubble at a guess?

Don't think so; just 'chuck out' = 'throw away' (single, definitional clue).
