Signaling (in)tolerance: Social evaluation and metaethical relativism and objectivism.

Prior work has established that laypeople do not consistently treat moral questions as being objectively true or as merely true relative to different perspectives. Rather, these metaethical judgments vary dramatically across moral issues and in response to different social influences. We offer a potential explanation by examining how objectivists and relativists are evaluated in different contexts.

Praise Is for Actions That Are Neither Expected nor Required.

In six studies, we examined two foundational questions about moral praise. First, what makes an action praiseworthy? In Study 1, participants reported that actions that exceed duties (compared with dutiful actions) deserve greater praise and are perceived as less likely to happen. Second, what do observers infer from praise? Praise may communicate information about local norms.

Are there conserved biosynthetic genes in lichens? Genome-wide assessment of terpene biosynthetic genes suggests ubiquitous distribution of the squalene synthase cluster.

Lichen-forming fungi (LFF) are prolific producers of functionally and structurally diverse secondary metabolites, most of which are taxonomically exclusive and play lineage-specific roles. To date, widely distributed, evolutionarily conserved biosynthetic pathways in LFF are not known. However, this idea stems from polyketide derivatives, since most biochemical research on lichens has concentrated on polyketide synthases (PKSs).

Neural patient-specific 3D-2D registration in laparoscopic liver resection.

Purpose: Augmented reality guidance in laparoscopic liver resection requires the registration of a preoperative 3D model to the intraoperative 2D image. However, 3D-2D liver registration poses challenges owing to the liver's flexibility, particularly in the limited visibility conditions of laparoscopy. Although promising, the current registration methods are computationally expensive and often necessitate manual initialisation.
