A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect.

We conducted a preregistered multilaboratory project ( = 36; = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the . Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( = 0.

Husbandry of Monodelphis domestica in the study of mammalian embryogenesis.

Monodelphis domestica, commonly called the laboratory opossum, is a useful laboratory animal for studying marsupial embryogenesis and mammalian development. Females breed year-round and the animals can be sustainably bred indoors. The authors draw on their own laboratory's experience to supplement previously published research on laboratory opossums.

Paleo-roothole facilitated transport of aromatic hydrocarbons through a Holocene clay bed.

A field study involving high-resolution core sampling of a 0.5-2 m thick clay bed was undertaken at a contaminated former industrial facility in the UK to establish the nature and significance of preferential contaminant flowpaths. In contrast to most previous research, the focus was upon a buried aquitard, in this case a Holocene lagoonal clay located 6 m below ground surface and overlain by a sand aquifer impacted by historic nonaqueous phase liquid hydrocarbon spills.
