Rather than reflect off of the sail, light is absorbed by the sponge, which converts that energy into propulsion."

No, gravity hasn't killed Schroedinger's cat. "it is a nice paper that points out an effect of macroscopic quantum systems in gravitational fields that had not previously been studied. This may become relevant for interferometry of large composite objects at some point. But it is an exceedingly weak effect, and I for sure am very skeptical that it can be measured any time in the soon future. This effect doesn’t teach us anything about Schrödinger’s cat or the measurement problem that we didn’t know already, and it for sure has nothing to do with quantum gravity."

When science gets ugly – the story of Philipp Lenard and Albert Einstein.

And speaking of things getting ugly, the discussion of Nobel Laureate Tim Hunt's ill-advised attempt at levity (or not, depending on which version of events you accept) continued to intensity. Hunt claimed, ‘I’ve been hung out to dry. They haven’t even bothered to ask for my side of affairs.’ Here is a Storify of Publizter-Prize-winning journalist Deborah Blum's tweets on the situation giving her firsthand counter-account (she was there and pressed him for clarification): Tim Hunt "jokes" about women scientists. Or not. Here's Why Many Think Tim Hunt's Sexist Comments Were No "Joke." As Blum later wrote in The Daily Beast:

"I do have sympathy for anyone caught in the leading edge of a media storm. But if we are ever to effect change, sometimes we need the winds to howl, to blow us out of our comfort zones.  Because the real point here isn’t about individuals, isn’t about Tim Hunt or me. The real point is our failure, so far, to make science a truly inclusive profession. The real point is that that telling a roomful of female scientists that they aren’t really welcome in a male-run laboratory is the sound of a slamming door. The real point is that to pry that door open means change. And change is hard, uncomfortable, and necessary."

And here's more about why it matters: Stories of sexism in science: 'sorry about all the women in this laboratory.' With that in mind, commentary has been shifting toward extracting something meaningful: Furor Over Tim Hunt Must Lead to Systemic Change. Related: After Tim Hunt, another science is possible.
