This study selected the Japanese macaque (Macaca fuscata) as a model animal for the fetal transfer of OH-PCBs in humans, and revealed OH-PCB concentrations and their relationships in the maternal and fetal brains. The key finding from this study is that OH-PCBs can reach the developing brain of the fetus as early as the first trimester of pregnancy. These OH-PCBs may exceed the levels that induce adverse effects on neurodevelopment.

Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An international team of researchers has realized a quantum technology to probe temperature on a nanometer-scale, and have observed a ‘fever’ in tiny nematode worms under pharmacological treatment. This strengthens the connection between quantum sensing and biology and ushers in novel thermal imaging technologies in biomedical research.

In catalytic reactions with organocatalysts, it is difficult to control radical reactions. We designed a thiazolium-type N-heterocyclic carbene catalyst having an N-neopentyl group. This catalyst was found to actively control radical reactions and enabled production of more than 35 species of bulky dialkyl ketones from an aliphatic aldehyde and an aliphatic carboxylic acid derivative through a radical relay mechanism. This catalyst is expected to open the way for acceleration of drug discovery research.

A hemispherical vanadium oxide cluster has a cavity that can accommodate a bromine molecule. It was found that a bromine molecule trapped in the cavity was polarized and that an alkane molecule like pentane, butane and propane could be brominated with the bromine molecule in the cavity with a selectivity differing from ordinary bromination. The present findings are expected to be useful for polarization of small molecules and design of highly functional catalysts.
