Time to get back to experiments

I seem to have run out of urgent desk-work (or my brain has conveniently forgotten what remains to be done) so I'm going to get back to the bench and do an experiment or two. What should I do?

Maybe I should test whether lab cultures of Bacillus subtilis grow better if given DNA they can use as a nutrient. I briefly posted about this last month. Or maybe I should try to find out whether the H. influenzae rec-2 gene is indeed regulated by the PurR repressor. Or get back to trying to find the conditions that cause E. coli to express its sxy gene and (we predict) become naturally competent. Or, farther back, continue last spring's preparations for laser-tweezers analysis of DNA uptake by H. influenzae.
