A major hub for cell-fate decisions
In a recently published study, LMU researchers show that, in a nerve-cell lineage in the nematode Caenorhabditis elegans, a single protein controls the rate of cell-cycle progression, and decides whether cells divide, differentiate ...

A microbe's fountain of youth
The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the ...
Gravitational tide the secret of Saturn's weird moon
Enceladus, a white moon of Saturn with ice-spewing volcanoes, owes its strangeness to tides of gravitational forces exerted by its mother, a study in Nature said on Wednesday.
To germinate, or not to germinate, that is the question
