The discovery of a gene that mediates periodic segmentation of the developing backbone of vertebrate embryos opened up research into how the pace of development is controlled by a molecular clock that has a species-specific rhythm.

Molecules of heavy water contain the deuterium isotope of hydrogen and have been impossible to separate from ordinary water. Nanoporous materials with flexible apertures in their structures point the way to a solution.

The generation of spatial maps that detail molecular and genetic information for the diverse cells and tissue environment of breast tumours offers insight into the factors that drive cancer progression.

The glacier in Greenland’s largest drainage basin is thinning and its flow is accelerating. Updated simulations suggest that sea-level rise will be up to fivefold higher than previously expected.
