Ruffner and Eric R. Weeks | | | The degree of polydispersity of colloidal suspensions is known to have consequences for their physical properties. Kurita et al. present a general method for determining the sizes of individual particles, and thus the polydispersity, using only the coordinates of the centre positions of spherical particles. | | | 09 Oct | Nat Commun 3:1127 doi:10.1038/ncomms2114 (2012) | | | Physical sciences Condensed matter | | | Fluids and plasma physics | | | | | | Abstract | Full Text | PDF (806 kB) |
| Cooling and stabilization by collisions in a mixed ion–atom system | | | K. Ravi, Seunghyun Lee, Arijit Sharma, G. Werth and S.A. Rangwala | | | Trapped ions and atoms coexist at different temperatures in mixed systems, and cooling of ions through collisions with atoms is required for the mixture to stabilize. Ravi et al. study these effects using rubidium atoms and ions, and find a collisional cooling mechanism leading to stability of the mixture. | | | 09 Oct | Nat Commun 3:1126 doi:10.1038/ncomms2131 (2012) | | | Physical sciences Atomic and molecular physics | | | Abstract | Full Text | PDF (557 kB) |
| Identifying the preferred RNA motifs and chemotypes that interact by probing millions of combinations | | | Tuan Tran and Matthew D. Disney | | | Identifying molecules that bind to RNA is difficult because information about RNA–ligand interactions is limited. Tran and Disney report a solution-based screening method that can probe large numbers of RNA motif-small molecule interactions to identify privileged RNA structures and chemical spaces that interact. | | | 09 Oct | Nat Commun 3:1125 doi:10.1038/ncomms2119 (2012) | | | Chemical sciences Biochemistry | | | Chemical biology Medicinal chemistry | | Abstract | Full Text | PDF (598 kB) |

Flavell, Boris Reizis, Zeli Shen, James G. Fox, Akiko Iwasaki and Ruslan Medzhitov | | | Mice lacking the anti-inflammatory cytokine IL-10 can develop colitis, which depends on inappropriate responses to commensal bacteria. Hoshi et al. now show that these responses are driven by colonic mononuclear phagocytes, providing insight to the initiating events, which may underlie inflammatory bowel disease. | | | 09 Oct | Nat Commun 3:1120 doi:10.1038/ncomms2113 (2012) | | | Biological sciences Immunology | | | | Abstract | Full Text | PDF (927 kB) |

Fallon and Paul N. Moynagh | | | One of the five IL-17 receptors, IL-17RD lacks a motif thought to be required for downstream signalling. Mellet et al. show that IL-17RD tunes IL-17A-dependent signalling; in its absence, MAPK signalling and neutrophil recruitment are impaired, but NF-κB activation is enhanced. | | | 09 Oct | Nat Commun 3:1119 doi:10.1038/ncomms2127 (2012) | | | Biological sciences Cell biology | | | Immunology Molecular biology | | Abstract | Full Text | PDF (1,060 kB) |

| Atmospheric phosphorus deposition may cause lakes to revert from phosphorus limitation back to nitrogen limitation | | | L. Camarero and J. Catalan | | | Increased atmospheric input of nitrogen has shifted planktonic lake nutrient systems from natural nitrogen to human-induced phosphorus limitation. This study proposes that decades of increased atmospheric phosphorus in the Pyrenean lake district may have reverted the system from phosphorus back to nitrogen-limited. | | | 09 Oct | Nat Commun 3:1118 doi:10.1038/ncomms2125 (2012) | | | Biological sciences Biogeochemistry | | | Ecology | | Abstract | Full Text | PDF (285 kB) |

Leemans | | | Computed tomography relies on scanning to measure an object from many angles, which fails for shot-to-shot changes and ultrafast phenomena. Matlis et al. demonstrate an approach based on spectral multiplexing for single-shot tomographic imaging and use it to measure femtosecond plasma filaments. | | | 09 Oct | Nat Commun 3:1111 doi:10.1038/ncomms2120 (2012) | | | Physical sciences Fluids and plasma physics | | | Optical physics | | | | | | Abstract | Full Text | PDF (1,251 kB) |

Schmidt, Dang Yuan Lei, Lothar Wondraczek, Virginie Nazabal and Stefan A.
