Let’s start off for a nice story from space.com that is right up my alley: merging galaxies and the growth of supermassive black holes in the very early universe. My specialty is quasars, the most luminous form of active galaxy out there, and these cosmic powerhouses are visible very close to, literally, the dawn of time. It’s still something of mystery exactly how we got such supermassive black holes to assemble so quickly, and investigations like this one are critical to develop this understanding.
OK, now for some biological science that seems to be getting some net attention concerning some proteins that play an evolutionary role. The sf take from io9, and the press release from Princeton. Despite words that clearly indicate there is no problem with evolution, I fear the spin on these results will not be well understood. The io9 article is already guilty of propagating the misconception that “evolution is random” which is NOT TRUE. Mutations are random. What has apparently been found here is a regulation mechanism at the cellular level for how to deal with some of the mutations that aren’t so good. I don’t think it’s correct to say, as in the io9 headline, that they “control” evolution. That sounds guided, like an intelligent agent is controlling the process. Evolution still works just fine, it’s still mutation, environment, and selection, but we’re learning about some new details.
An article by Chris Mooney about “Science under Obama.” This is of great interest to me, and hopefully everyone.
There’s a blog I just learned about called The Big Storm Picture. It’s about pictures of big storms, duh. All I can say is awesome!

io9. A million light years wide and a micron deep. I gave up on the site long ago.
