| A model of parity-dependent immunity to placental malaria OPEN | | | Patrick G. T. Walker, Jamie T. Griffin, Matt Cairns, Stephen J. Rogerson, Anna M. van Eijk, Feiko ter Kuile and Azra C. Ghani | | | Exposure to malaria during pregnancy can result in its spread to the placenta; however, the risk of placental infection decreases with subsequent pregnancies. By constructing a mathematical model, the authors find that this is likely due to a reduction in the duration of infection rather than a reduced risk of transfer. | | | 19 Mar | Nat Commun 4:1609 doi:10.1038/ncomms2605 (2013) | | | Biological sciences Immunology | | | Medical research | | Abstract | Full Text | PDF (1,173 kB) |

| Environmental variability promotes plant invasion | | | Madalin Parepa, Markus Fischer and Oliver Bossdorf | | | Environmental conditions are likely to become more temporally variable with global environmental change.

| Adaptive sex allocation in anticipation of changes in offspring mating opportunities | | | Andrew T. Kahn, Hanna Kokko and Michael D. Jennions | | | For parents, sons are more evolutionarily lucrative than daughters if sons get more chances to breed (and vice versa). Kahn et al. find that mosquitofish take advantage of this: they anticipate the future mating prospects of their offspring and bias production towards the sex with greater opportunities. | | | 19 Mar | Nat Commun 4:1603 doi:10.1038/ncomms2634 (2013) | | | Biological sciences Ecology | | | Evolution Zoology | | Abstract | Full Text | PDF (450 kB) |

Belotelov, Bernd Stritzker and Harald Giessen | | | The Faraday effect rotates the polarization plane of light in magneto-optical materials and is used for optical isolators blocking unwanted backscattering of light. Usually a small effect, Chin et al. have observed a large enhancement of the optical rotation by magneto-plasmonics. | | | 19 Mar | Nat Commun 4:1599 doi:10.1038/ncomms2609 (2013) | | | Physical sciences Applied physics | | | Optical physics | | | Abstract | Full Text | PDF (943 kB) |

G. Porter, Jackie Russell, Konstantin I. Panov and Joost C. B. M. Zomerdijk | | | Topoisomerases facilitate the progress of elongating polymerases during transcription. Zomerdijk and colleagues now demonstrate an additional role for this enzyme; their data suggest that Top2 can cleave DNA inducing topological changes at the ribosomal DNA promoter, which assists de novo assembly of the RNA polymerase I pre-initiation complex. | | | 19 Mar | Nat Commun 4:1598 doi:10.1038/ncomms2599 (2013) | | | Biological sciences Molecular biology | | | | Abstract | Full Text | PDF (2,384 kB) |
