We investigate how knowledge similarity between two individuals is systematically related to the likelihood that a serendipitous encounter results in knowledge production. We conduct a field experiment at a medical research symposium, where we exogenously varied opportunities for face‐to‐face encounters among 15,817 scientist‐pairs. Our data include direct observations of interaction patterns collected using sociometric badges, and detailed, longitudinal data of the scientists' postsymposium publication records over 6 years. We find that interacting scientists acquire more knowledge and coauthor 1.2 more papers when they share some overlapping interests, but cite each other's work between three and seven times less when they are from the same field. Our findings reveal both collaborative and competitive effects of knowledge similarity on knowledge production outcomes.

Introgression plays a key role in adaptive evolution and species diversification in many groups of species including Heliconius butterflies. However, frequent hybridization and gene flow between species makes estimation of the species phylogeny challenging, especially for rapidly speciating species within adaptive radiations. Here, we analyze the genomic sequences from six members of the erato-sara clade of Heliconius butterflies to infer the species phylogeny and cross-species introgression events. To avoid heterozygote phasing errors in haploid sequences commonly produced by genome assembly methods, we processed and compiled unphased diploid sequence alignments, with the analytical methods averaging over uncertainties in heterozygote phase resolution. We use likelihood-based methods under the multispecies coalescent (MSC) model with and without gene flow to accommodate random fluctuations in genealogical history across the genome due to deep coalescence. There is robust evidence of introgression across the genome, both among distantly related species deep in the phylogeny and between sister species in shallow parts of the tree. We obtain estimates of population parameters such as introgression times and probabilities, species divergence times, and population sizes for modern and ancestral species. We confirm ancestral gene flow between the sara clade and an ancestral population of likely hybrid origin of H. telesiphe, a likely hybrid origin of H. hecalesia, and gene flow between the sister species H. erato and H. himera. Our approach also demonstrates how introgression among ancestral species can explain the history of two chromosomal inversions deep in the phylogeny of the group. For the first time, we not only test for the presence of cross-species gene flow, but also estimate its direction, timing and magnitude, extracting rich historical information of species divergence and gene flow from genomic data

Universities require faculty and students planning research involving human subjects to pass formal certification tests and then submit research plans for prior approval. Those who diligently take the tests may better understand certain important legal requirements but, at the same time, are often misled into thinking they can apply these rules to their own work which, in fact, they are not permitted to do. They will also be missing many other legal requirements not mentioned in their training but which govern their behaviors. Finally, the training leaves them likely to completely misunderstand the essentially political situation they find themselves in. The resulting risks to their universities, collaborators, and careers may be catastrophic, in addition to contributing to the more common ordinary frustrations of researchers with the system. To avoid these problems, faculty and students conducting research about and for the public need to understand that they are public figures, to whom different rules apply, ones that political scientists have long studied. University administrators (and faculty in their part-time roles as administrators) need to reorient their perspectives as well. University research compliance bureaucracies have grown, in well-meaning but sometimes unproductive ways that are not required by federal laws or guidelines. We offer advice to faculty and students for how to deal with the system as it exists now, and suggestions for changes in university research compliance bureaucracies, that should benefit faculty, students, staff, university budgets, and our research subjects.

Once considered "weird wonders" of the Cambrian, the emblematic Burgess Shale animals Anomalocaris and Opabinia are now recognized as lower stem-group euarthropods. Anomalocaris and its relatives (radiodonts) had a worldwide distribution and survived until at least the Devonian, whereas - despite intense study - Opabinia remains the only formally described opabiniid to date. Here we reinterpret a fossil from the Wheeler Formation of Utah as a new opabiniid, KUMIP 314087. By visualizing the sample of phylogenetic topologies in treespace, our results fortify support for the position of KUMIP 314087 beyond the nodal support traditionally applied. Our phylogenetic evidence expands opabiniids to multiple Cambrian Stages spanning approximately five million years. Our results underscore the power of treespace visualization for resolving imperfectly preserved fossils and expanding the known diversity and spatiotemporal ranges within the euarthropod lower stem group.
