Hi guys, Sci here. I’m afraid that things are more stressed than usual at around these parts. In fact, I may really, finally, have bitten off more than I can chew. So, things are going to be slow around here for a while. I’ll have posts up on Mondays at SciAm as usual. Fridays will be reposts because you, and I, cannot live without our weird science. I might be able to resurface in three weeks or so. Thanks.
