New toothpaste stops gum disease without killing good bacteria

Across Earth, every night, thousands of automated stargazers are waiting to take pictures of shooting stars. I am one of the scientists who study these meteors.

Decomposition of dead leaves in Veluwe forests has declined by tens of percent since the turn of the century. Meteorologists from Wageningen University & Research discovered this in an analysis of long-term measurements. The cause appears to lie in soil acidity. This is noteworthy because nitrogen deposition in the area has actually decreased over the same period. The effects of nitrogen entering the ecosystem in the past may still be lingering.

Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.

A new study led by researchers at the Institute of Materials Science of Barcelona (ICMAB-CSIC) reveals why a particular boron-rich molecule, called o-FESAN, behaves in an unusually helpful way, remaining intercalated into DNA even though it was thought it should be repelled by it. The paper is published in the journal Aggregate and builds on research published in 2024 in the Journal of Materials Chemistry B.
