The biggest physics news this week is the announcement of possible hints of dark matter in Fermi data, namely, a curious excess of gamma-ray light coming from the center of our galaxy. Could this be a sighting of dark matter turning visible at the center of our galaxy? For a bit more background, here’s Natalie Wolchover’s March 3 Quanta article with more details, along with my own Quanta article from last summer.
On the shameless self-promotion front, I chatted with Calla Cofield on the Physics Central podcast about the physics hidden in my new book, Me, Myself and Why: Searching for the Science of Self. And I have a new article up at Quanta, Self-Organized Criticality: A Fundamental Theory to Model the Mind?
This past week was April Fool’s Day, a guess what? Scientists have a sense of humor too. In-house, check out Unscientific Unamerican, and Other April Fools’ Jokes in Scientific American‘s long history. Also: Graham’s Number Is Too Big for Evelyn Lamb to Tell You How Big It Is. Over at Slate, Phil Plait offered an April Fool debunking: No, there’s no such thing as a planet-dissolving Chaos Cloud. Here’s A Chemistry Prank From the April 1939 Issue Of Popular Science. Bonus humor: Scientists must use more jargon for public to appreciate science, study shows. “Remind us how smart you are—use five-syllable words, or better yet, Latin.”
Shake, Rattle, and Roll in Los Angeles: we had a pretty good-sized quake earlier in the week — although nothing like the one that hit Chile a couple of days ago — prompting some ruminations on the science of earthquakes.

Did you miss my latest Cosmos recap? It’s all relative except PATRICK STEWART! As usual, there was some discontent, particularly over the fact that an episode in which William Herschel and his son John were prominently featured never once mentioned another notable member of the family, astronomer Caroline Herschel. But not so fast? The next episode airing on Sunday is called “Sisters of the Sun,” and focuses on several women in science.
