Observations on a 10-kg Graphite Nodule from the Canyon Diablo (iab-mg) Iron Meteorite

Observations from a 4-year contamination study of a sample depth profile through Martian meteorite Nakhla.

Morphological, compositional, and biological evidence indicates the presence of numerous well-developed microbial hyphae structures distributed within four different sample splits of the Nakhla meteorite obtained from the British Museum (allocation BM1913,25). By examining depth profiles of the sample splits over time, morphological changes displayed by the structures were documented, as well a...

Inferring causal networks from observations and interventions

Information about the structure of a causal system can come in the form of observational data— random samples of the system’s autonomous behavior—or interventional data—samples conditioned on the particular values of one or more variables that have been experimentally manipulated. Here we study people’s ability to infer causal structure from both observation and intervention, and to choose info...
