Dynamic Covalent Radical Recombination for the Assembly of Tuneable Responsive Porous Organic Cages
Dynamic covalent chemistry (DCC) based on reversible radical recombination enables the assembly of responsive, C─C‐linked organic cages. Substituent‐controlled aryldicyanomethyl radicals form discrete, porous architectures with tuneable topology of Tri2 and Tri4 cages, gas selectivity, chromism, and self‐healing behaviour, establishing radical‐based ...

tanggle: An R package for the visualization of phylogenetic networks
Abstract Premise Phylogenetic trees depict evolutionary relationships among taxa. However, they are strictly bifurcating structures that do not take into account several types of evolutionary events such as horizontal gene transfer, hybridization, or introgression. Although the development of new methods in phylogenetic networks has recently increased,

Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.
