For the first time, astrophysicists detected a supernova embedded in a wind rich with silicon, sulfur and argon. Observations suggest the massive star lost its outer hydrogen and helium layers long before exploding. Discovery offers direct evidence of the long-theorized inner shell structure of massive stars.

Scientists and chefs have collaborated on a new study that demonstrates how fermented foods can be used to drive participatory science projects that both engage the public and advance our understanding of microbial ecology. The study focused on working with food experts and the public to examine the microbial communities associated with kombucha, kimchi and chow chow.
