Ruthenium-catalyzed <i>O</i>- to S-alkyl migration
A practical ruthenium-catalyzed O- to S-alkyl migration affords structurally diverse thiooxazolidinones in excellent yields. Our studies suggest this catalytic transformation proceeds through a pseudoreversible radical...
Precise control of Cu$_2$O nanostructures and LED-assisted photocatalysis
We describe the synthesis and characterization of a high-efficiency visible light Cu$_2$O photocatalyst. Uniform cubic, octahedral and rhombic dodecahedral Cu$_2$O nanocrystals with a size of 300–600 nm were synthesized using a...
Short-Term Response of Cytosolic N O 3 - to Inorganic Carbon Increase in Posidonia oceanica Leaf Cells.
The concentration of CO2 in the atmosphere has increased over the past 200 years and is expected to continue rising in the next 50 years at a rate of 3 ppm·year-1. This increase has led to a decrease in seawater pH that has...

Improved bounds for the Erdős-Rogers function
The Erd\H{o}s-Rogers function $f_{s,t}$ measures how large a $K_s$-free
induced subgraph there must be in a $K_t$-free graph on $n$ vertices. While
good estimates for $f_{s,t}$ are known for some pairs $(s,t)$, notably...
Horizontally acquired divergent O-antigen contributes to escape from cross-immunity in the classical bordetellae

Background:
Horizontal gene transfer (HGT) allows for rapid spread of genetic material between species, increasing genetic and phenotypic diversity. Although HGT contributes to adaptation and is widespread in many bacteria...
