Using a combination of metal‐promoted reactivity, in‐situ covalent bond modification, and hydrogen bonding‐promoted fluorine labilization, a unified approach was developed to self‐assemble a library of customizable ligand architectures directly at the nickel center via selective cleavage of C‒F or C‒O bonds and the formation of C‒C or C‒N bonds.

Enhancing Signal Purity in Josephson Structure Measurements
A low‐noise signal measurement system for dilution refrigerators is presented, combining multistage cryogenic filtering and electromagnetic shielding to suppress broad‐spectrum noise. The setup enables sub‐nanoampere switching current measurements in Josephson junctions, surpassing commercial systems.

Hypercanines: Not just for sabertooths
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
