EDITORS' SUGGESTION
A new ecosystem model, which accounts for metabolic trade-offs between coexisting species, shows that population diversity can increase even when species compete for the same limited nutrients, a finding that replicates nature.

A temperature induced phase transition occurs in water molecules packed single-file inside a carbon nanotube, as shown by photoluminescence measurements and first-principles calculations.

EDITORS' SUGGESTION
A theoretical analysis suggests that quantum mechanical violations of energy conservation may arise in some proposed models of quantum gravity. If realized in nature, these violations could manifest on cosmological scales as an effective cosmological constant.

EDITORS' SUGGESTION
Conventional diffraction theory is predicted to break down for x-rays when spontaneous scattering is replaced by stimulated scattering by a thin film source. The stimulated diffraction pattern generated by the cooperative interaction of two coherent, unentangled photons results in self-focussing beyond the diffraction limit.

EDITORS' SUGGESTION
The LHCb collaboration has identified four new structures in B+ decays that are likely to be tetraquark states. These tetraquark systems contain neither of the light u and d quarks.
