The path to gypsum is four steps long

Drywall and plasters made from both natural and manufactured gypsum are commonly used in home and building construction around the world, in part because of gypsum’s widespread availability. Despite its abundance, and its seemingly simple makeup, however, relatively little is known about how the calcium sulfate mineral forms in nature. In a recent study, researchers have shed new light on the multi-stage process by which gypsum grows — and the findings could help develop more efficient ways to manufacture the material.

Burgess Shale fossil find offers glimpse of early parenting

Parenting behaviors of many modern animals are well known. Marsupials, like kangaroos, keep their young in pouches, and brown bear mothers are famously protective of their offspring, for example.

Now, a new study has shed light on one of the earliest demonstrated examples of parental behavior in animals: brood care among ancient shrimplike arthropods.
