Abstract The conversion of carbonyls to olefins is a transformation of great importance for complex molecule synthesis.

A new study shows that subglacial melting may provide an answer, significantly extending the habitability region, in particular around M-dwarf stars, which a

It has been understood for some time that microplastics provide a protective environment (the so-called "plastisphere") in which bacteria can survive in wastewater. For the first time, researchers at the University of Stirling, Scotland, have tracked how that could enable bacteria to survive the journey to the sea and make their way onto our beaches, where they can come into contact with humans.
