Heat management with a twist in layered materials p.637

The misalignment of crystal lattices in stacked monolayers of materials has been shown to prevent heat flow between the layers, while retaining flow within them. This finding opens up an inventive way to control heat at the nanoscale.

Pollination advantage of rare plants unveiled p.638

An analysis of plant–pollinator interactions reveals that the presence of abundant plant species favours the pollination of rare species. Such asymmetric facilitation might promote the coexistence of species in diverse plant communities.

Electron crystals come under the microscope p.640

In 2D materials, electrons at low densities can freeze into well-defined positions and form exotic structures called Wigner crystals. A non-invasive technique has been developed to image these crystals directly.

Insights into the origins of pancreatic cancer p.641

The initial events that give rise to pancreatic cancer are not fully understood. Evidence from mice now implicates the enzyme Tert in setting the stage for the formation of this type of tumour.
