Article Abstract
The taxonomy of the genus Incisus Grishin, 2019 is reviewed, including redescriptions of known species, the description of a new species, Incisus mineirus sp. nov., identification keys, and an updated distribution map. Images of the genitalia for each species are included, with the female genitalia being illustrated for the first time. A lectotype and paralectotype for Antigonus incisus Mabille, 1878, and neotypes for Staphylus ordinarius Hayward, 1933 and Nisoniades aterea Plötz, 1884, are designated. Staphylus ordinarius Hayward, 1933 is a syn. nov. of Incisus fasciatus (Hayward, 1933). Antigonus variegatus Mabille, 1878 is a syn. nov. of Nisoniades macarius Herrich-Schäffer, 1870, and Staphylus dentivittata Hayward, 1933 is a syn. nov. of Staphylus musculus (Burmeister, 1875). Additionally, the subgeneric name Stolla Grishin, 2023 is a syn. nov. of Uniphylus Lemes, Siewert, Mielke, Casagrande & Warren, 2023.

A number of Pd based materials have been synthesised and evaluated as catalysts for the conversion of carbon dioxide and hydrogen to methanol, a useful platform chemical and hydrogen storage molecule. Monometallic Pd catalysts show poor methanol selectivity, but this is improved through the formation of Pd alloys, with both PdZn and PdGa alloys showing greatly enhanced methanol productivity compared with monometallic Pd/AlO and Pd/TiO catalysts. Catalyst characterisation shows that the 1 : 1 β-PdZn alloy is present in all Zn containing post-reaction samples, including PdZn/GaO, with the PdGa alloy formed for the Pd/GaO sample.

The rise in atmospheric CO concentration and the concomitant rise in global surface temperature have prompted massive research effort in designing catalytic routes to utilize CO as a feedstock. Prime among these is the hydrogenation of CO to make methanol, which is a key commodity chemical intermediate, a hydrogen storage molecule, and a possible future fuel for transport sectors that cannot be electrified. Pd/ZnO has been identified as an effective candidate as a catalyst for this reaction, yet there has been no attempt to gain a fundamental understanding of how this catalyst works and more importantly to establish specific design criteria for CO hydrogenation catalysts.

Our expanded efforts in genomic sequencing to cover additional skipper butterfly (Lepidoptera: Hesperiidae) species and populations, including primary type specimens, call for taxonomic changes to restore monophyly and correct misidentifications by moving taxa between genera and proposing new names. Reconciliation between phenotypic characters and genomic trees suggests three new tribes, two new subtribes, 23 new genera, 17 new subgenera and 10 new species that are proposed here: Psolosini Grishin, (type genus Staudinger, 1889), Ismini Grishin, (type genus Distant, 1886), Eetionini Grishin, (type genus de Nicéville, 1895), Orphina Grishin, (type genus Godman, 1901), Carystoidina Grishin, (type genus Godman, 1901), Grishin, (type species Plötz, 1882), Grishin, (type species Mabille and Boullet, 1912), Grishin, (type species Grishin, ), Grishin, (type species Plötz, 1884), Grishin, (type species Evans, 1937), Grishin, (type species Trimen, 1873), Grishin, (type species Hayward, 1951), Grishin, (type species Mabille, 1889), Grishin, (type species ?

Structural and Computational Biology Unit, European Molecular Biology Laboratory, Heidelberg, Germany.
The gastrointestinal tract is abundantly colonized by microbes, yet the translocation of oral species to the intestine is considered a rare aberrant event, and a hallmark of disease. By studying salivary and fecal microbial strain populations of 310 species in 470 individuals from five countries, we found that transmission to, and subsequent colonization of, the large intestine by oral microbes is common and extensive among healthy individuals. We found evidence for a vast majority of oral species to be transferable, with increased levels of transmission in colorectal cancer and rheumatoid arthritis patients and, more generally, for species described as opportunistic pathogens.
