My former undergad Hannah Tam gave a phenomenal PhD dissertation talk earlier today on the mechanisms of skin regeneration in mice!! So proud and such joy to see her shine so brightly! We had a mini lab reunion too, with Hannah and former undergad Juli Stanley.

I had a great time at the #IgNobel prize ceremony!
And what a show! Paper airplanes, an opera about digestion, all celebrating achievements that first make you laugh and then think.

Mutations in the daf-2 gene double the lifespan of C. elegans worms, but they have no effect on lifespan if the daf-16 gene is mutated.

Good thing I took so many history of science classes back in college 30 years ago!
I am going through my dusty notes from "The Rise of Modern Science" and "American Science: Ethical Conflicts and Political Choices," reading about the creation of the National Science Foundation after World War II.

Yen-Ping Hsueh and her lab have done amazing work looking at how oyster mushrooms (Pleurotus ostreatus) kill C. elegans: They make these lollipop-shaped structures (toxocysts) on the hyphae, and load them with a ketone (3-octanone) that kills the worms (DOI: 10.1126/sciadv.ade4809).
