The January 2012 issue of Nature Cell Biology presents a series of review articles by leading scientists on recent developments in membrane dynamics — including endocytosis, and vesicle biogenesis and transport — and the importance of these processes in development and disease.

| | | | | | Latest Articles | View all Articles | | | | | Synthetic quorum-sensing circuit to control consortial biofilm formation and dispersal in a microfluidic device OPEN | | | Seok Hoon Hong, Manjunath Hegde, Jeongyun Kim, Xiaoxue Wang, Arul Jayaraman and Thomas K. Wood | | | Engineered biofilms have applications in biorefineries. Here, Hong et al. engineer bacteria to produce a combination of dispersal proteins and quorum sensing factors, and show that one dispersing bacterium can eliminate a biofilm formed by a colonizing bacterium. | | | 03 Jan | Nat Commun 3:613 doi:10.1038/ncomms1616 (2012) | | | Biological sciences Cell biology | | | Microbiology | | Abstract | Full Text | PDF (1,362 kB) |
Supplementary Information |
| Measurement of finite-frequency current statistics in a single-electron transistor OPEN | | | Niels Ubbelohde, Christian Fricke, Christian Flindt, Frank Hohls and Rolf J. Haug | | | Fluctuations of the electrical current in nanoscale devices reveal important details of the physical processes occurring inside them. Using a quantum point contact placed in its vicinity, Ubbelohde et al. measure the electrical fluctuations in a single-electron transistor, and determine the dynamical features of the transport. | | | 03 Jan | Nat Commun 3:612 doi:10.1038/ncomms1620 (2012) | | | Physical sciences Applied physics | | | Condensed matter Nanotechnology | | | Abstract | Full Text | PDF (799 kB) |
| Advantage of rare infanticide strategies in an invasion experiment of behavioural polymorphism OPEN | | | Tapio Mappes, Jouni Aspi, Esa Koskela, Suzanne C. Mills, Tanja Poikonen and Juha Tuomi | | | The origin and maintenance of non-parental infanticide is a puzzling phenomenon in wild animal populations. This study of infanticide in a population of bank voles confirms negative frequency-dependent selection in nature and shows potential benefits of this apparently harmful behaviour. | | | 03 Jan | Nat Commun 3:611 doi:10.1038/ncomms1613 (2012) | | | Biological sciences Ecology Evolution | | | Abstract | Full Text | PDF (319 kB) |
| Structure-based mutagenesis reveals the albumin-binding site of the neonatal Fc receptor OPEN | | | Jan Terje Andersen, Bjørn Dalhus, Jason Cameron, Muluneh Bekele Daba, Andrew Plumridge, Leslie Evans, Stephan O. Brennan, Kristin Støen Gunnarsen, Magnar Bjørås, Darrell Sleep and Inger Sandlie | | | Albumin transport proteins circulate in the blood and are protected from degradation by interaction with the neonatal Fc receptor. Andersen et al. investigate the albumin binding site of the neonatal Fc receptor and find pH sensitive ionic networks at the binding interface. | | | 03 Jan | Nat Commun 3:610 doi:10.1038/ncomms1607 (2012) | | | Biological sciences Bioengineering | | | Immunology Molecular biology | | Abstract | Full Text | PDF (1,256 kB) |

| Approaching the ideal elastic limit of metallic glasses OPEN | | | Lin Tian, Yong-Qiang Cheng, Zhi-Wei Shan, Ju Li, Cheng-Cai Wang, Xiao-Dong Han, Jun Sun and Evan Ma | | | The elastic limit represents the maximum stress and strain a material can withstand and is well characterized in many crystalline solids, yet remains elusive for metallic glasses. Here, this limit is investigated in submicron metallic glass structures and is found to be twice as high as that of bulk samples. | | | 03 Jan | Nat Commun 3:609 doi:10.1038/ncomms1619 (2012) | | | Physical sciences Applied physics | | | Materials science Nanotechnology | | Abstract | Full Text | PDF (666 kB) |

| Muscle-derived stem/progenitor cell dysfunction limits healthspan and lifespan in a murine progeria model OPEN | | | Mitra Lavasani, Andria R. Robinson, Aiping Lu, Minjung Song, Joseph M. Feduska, Bahar Ahani, Jeremy S. Tilstra, Chelsea H. Feldman, Paul D. Robbins, Laura J. Niedernhofer and Johnny Huard | | | The function of adult stem cells is diminished with age but the role this dysfunction plays in the aging process is unknown. Here, the injection of muscle-derived stem/progenitor cells from young mice rescues symptoms in progeroid mice and is shown to regenerate tissues independent of engraftment. | | | 03 Jan | Nat Commun 3:608 doi:10.1038/ncomms1611 (2012) | | | Biological sciences Cell biology | | Abstract | Full Text | PDF (2,939 kB) |
Supplementary Information |
| Inhibition of specific gene expressions by protein-mediated mRNA interference | | | Yoshihiro Yamaguchi, Hirofumi Nariya, Jung-Ho Park and Masayori Inouye | | | RNA can be silenced in a sequence-specific manner but whether proteins can silence RNA in this way is unknown. Now, Yamaguchi and colleagues show that an enzyme isolated from Haloquadra walsbyi cleaves 7-base-pair sequences in Escherichia coli, and this high sequence specificity permits the silencing of targeted genes. | | | 03 Jan | Nat Commun 3:607 doi:10.1038/ncomms1621 (2012) | | | Biological sciences Biochemistry | | | Biotechnology Microbiology | | Abstract | Full Text | PDF (805 kB) |

| Violation of a Leggett–Garg inequality with ideal non-invasive measurements | | | George C. Knee, Stephanie Simmons, Erik M. Gauger, John J.L. Morton, Helge Riemann, Nikolai V. Abrosimov, Peter Becker, Hans-Joachim Pohl, Kohei M. Itoh, Mike L.W. Thewalt, G. Andrew D. Briggs and Simon C. Benjamin | | | Quantum mechanics predicts that objects can simultaneously exist in a superposition of two states. Knee et al. propose and demonstrate experimentally a protocol which fully confirms this prediction, by testing the so-called Leggett–Garg inequality in a non-invasive manner. | | | 03 Jan | Nat Commun 3:606 doi:10.1038/ncomms1614 (2012) | | | Physical sciences Atomic and molecular physics | | | Theoretical physics | | Abstract | Full Text | PDF (489 kB) |

Hodson, Marie Schaeffer, Nicola Romanò, Pierre Fontanaud, Chrystel Lafont, Jerome Birkenstock, François Molino, Helen Christian, Joe Lockey, Danielle Carmignac, Marta Fernandez-Fuente, Paul Le Tissier and Patrice Mollard | | | Experience-dependent plasticity and functional adaptation are thought to be restricted to the central nervous and immune systems. This study shows that long-lasting experience-dependent plasticity is a key feature of endocrine cell networks, allowing improved tissue function and hormone output following repeat demand. | | | 03 Jan | Nat Commun 3:605 doi:10.1038/ncomms1612 (2012) | | | Biological sciences Cell biology | | | Neuroscience | | | Systems biology | | Abstract | Full Text | PDF (2,038 kB) |

Rosi | | | Metal‐organic framework (MOFs) with metal‐carboxylate cluster vertices and long, branched organic linkers are highly porous. An et al. develop an alternative route to MOFs in which metal‐biomolecule clusters are used as vertices to construct a mesoporous MOF. | | | 03 Jan | Nat Commun 3:604 doi:10.1038/ncomms1618 (2012) | | | Chemical sciences Inorganic chemistry | | | Materials science | | | Nanotechnology | | Abstract | Full Text | PDF (793 kB) |

This study shows that macroscopic gel assembly can be regulated through photoisomerization of an azobenzene moiety that interacts differently with two host molecules. | | | 03 Jan | Nat Commun 3:603 doi:10.1038/ncomms1617 (2012) | | | Chemical sciences Materials science | | | | Abstract | Full Text | PDF (434 kB) |
