  • Granular materials, ranging from fruit to rocks to powders, can change rapidly from a static jammed state to a free-flowing state. Insight from dynamical systems theory reveals that this tendency is governed by the growth of instabilities, rather than stress on individual particles.

  • In our understanding of planetary formation, it is still unclear how millimetre-sized dust grains grow into centimetre-sized aggregates. Microgravity experiments now show that electrical charging of the grains leads to the formation of larger clumps.

  • Wind-blown desert sands can charge up spontaneously. But although sand flow and the forces on charged bodies are well studied separately, surprisingly little is known of what happens when the two combine.

  • The mixing of festive sweetmeats and the stirring of cream into coffee are toothsome examples of the irreversibility of physical processes. In certain systems, however, the concept gets its just desserts.

  • In a box of mixed nuts, the brazils rise to the top. In granular mixtures in general, depending on their size and density, the ‘brazil nuts’ may sink instead. This reverse effect has now been explored further.

  • The Cancer Genome Atlas consortium reports on their genome-wide characterization of somatic alterations in colorectal cancer; in addition to revealing a remarkably consistent pattern of genomic alteration, with 24 genes being significantly mutated, the study identifies new targets for therapeutic intervention and suggests an important role for MYC-directed transcriptional activation and repression.

  • Triboelectric charging is well known to us all and has widespread and important consequences. Nonetheless, its most basic foundations remain poorly understood, and progress is often countered by the emergence of baffling new observations. Recent work shows the difficulty may arise because charging is governed by competing and unstable dynamical processes.
