Space-saving tips to lower stress

Space-saving tips to lower stress, Published online: 27 November 2017; doi:10.1038/s41567-017-0012-9

Understanding how some single cells evolved into multicellular life means figuring out how they overcome the stresses associated with crowding as they multiply. New insights from yeast suggest that changes in the shape of cells may provide an answer.

Quantum physics dropwise

Quantum physics dropwise, Published online: 27 November 2017; doi:10.1038/s41567-017-0015-6

Classical wave-driven particles can mimic basic quantum properties, but how far this parallel extends is yet to be seen. Evidence for quantum-like mirages in a system of droplets moving on a fluid surface pushes the analogy into many-body territory.

Cellular packing, mechanical stress and the evolution of multicellularity, Published online: 27 November 2017; doi:10.1038/s41567-017-0002-y

Understanding how single cells evolved into multicellular organisms requires knowledge of the physical constraints on the evolution of cell clusters. Evidence that an evolution in cell shape delays fracturing offers a route to increased complexity.

Superradiance of an ensemble of nuclei excited by a free electron laser, Published online: 20 November 2017; doi:10.1038/s41567-017-0001-z

Multiphoton superradiance is observed in a nuclear system excited by an X-ray free-electron laser. Tracking the system decay photon by photon shows strong enhancement of the first photon’s decay rate, in good agreement with Dicke’s formulation.

Topologically protected refraction of robust kink states in valley photonic crystals, Published online: 13 November 2017; doi:10.1038/nphys4304

NatureArticleSnippet(type=short-summary, markup=

A photonic crystal can realize an analogue of a valley Hall insulator, promising more flexibility than in condensed-matter systems to explore these exotic topological states.

How drops start sliding over solid surfaces

How drops start sliding over solid surfaces, Published online: 06 November 2017; doi:10.1038/nphys4305

NatureArticleSnippet(type=short-summary, markup=

A liquid droplet is shown to slide across a solid surface subject to friction forces analogous with those between two solids. The phenomenon is generic, and closes a gap in our understanding of liquid–solid friction.
