I'm presently stuck with what I've been working on lately. It's the really, really frustrating phase. Once you start looking into the details of an idea, problems occur to you that you previously weren't aware of. So then you have to rethink, read more papers, try differently. Sometimes it just doesn't work no matter what you try. One day it seems to work, the next day you figure out a mistake, then you find a better way, and that doesn't work either, and so on. Sigh.
But there's also good news from my work life: two of my recent papers "A model for non-singular black hole collapse and evaporation" with Leonardo Modesto and Isabeau Prémont-Schwarz, and "Conservative solutions to the black hole information problem" with Lee Smolin were just accepted for publication in PRD. So now we have to read the proofs. I like that part.
Besides that, I learned recently that the Royal Society has their 350th anniversary this year. They are celebrating the occasion with some open access special issues of the Philosophical Transactions, and they have an interactive timeline marking important papers, eg 1891 the proof that fingerprints are unique. One never stops learning. If you have an interest in the history of science, check this out.
Another news item is that the American Physical Society is giving blogging a try. They've called it "Physics Frontline" and according to their description cover "the latest scientific news, analysis and commentary on the intersection of physics with science policy issues, including innovation, education, energy, climate change, and nuclear policy." Despite presently 7 contributors, blogging is somewhat scarce there. Anyway, I think it's a good idea to provide commentary on science policy from people who actually know what they're talking about, and I thus hope to see somewhat more activity over there in the future.
