With a mortar and pestle, Christy Till blends together the makings of a distant planet. In her geology lab at Arizona State University in Tempe, Till carefully measures out powdered minerals, tips them into a metal capsule and bakes them in a high-pressure furnace that can reach close to 35,000 times Earth’s atmospheric pressure and 2,000° Celsius.
In this interplanetary test kitchen,...
Starve the tumor, not the cell
Animal experiments demonstrate for the first time that transplanted tumors release a chemical into the host’s bloodstream that causes the host to produce blood vessels to supply the tumor.… If such a factor can be identified in human cancers … it might be possible to prevent the vascularization of tumors. Since tumors above a certain small size require...

Physicists are ramping up their search for neutrinoless double beta decay, which could help explain why there is more matter in the universe than antimatter, Emily Conover reported in “The quest to identify the nature of the neutrino’s alter ego is heating up” (SN: 3/17/18, p. 14).
Reader F L Stiles wondered how this decay could explain a surplus of matter. “It...
