The link between these microbes and our health is the focus of a growing number of research initiatives, and new insights are emerging rapidly, some of which we are proud to present in this special collection. ▼ more       Biological Sciences More Biological sciences ▼   Structure, function and diversity of the healthy human microbiome   A large-scale resource for investigating microbial communities throughout the human body and an analysis of these data is reported in two studies in Nature this week. The data, from the Human Microbiome Project Consortium, provide a platform for future studies of the dynamics of the human microbiome and its impacts on human health.       Earth & Environmental Sciences More Earth & Environmental sciences ▼   Possible tropical lakes on Titan from observations of dark terrain   Saturn's moon Titan has a methane cycle similar in principle to Earth's water cycle, though surface liquid is scarce on Titan, detected mainly at high latitudes. This paper reports near-infrared spectral images of an area in the tropics with an unusual dark surface, which could indicate the presence of liquid methane on the surface, supplied by an underground reservoir.                   Nature Outlook: Breast Cancer Each year, 1.3 million women - and some 13,000 men - are diagnosed with breast cancer. The past few decades have seen huge advances in treatment, but about one-quarter of those diagnosed will die from the disease. The difficult challenges are only just starting. Access the Outlook free online for six months. Produced with support from: Saisei Mirai                 Earth & Environmental Sciences More Earth & Environmental sciences ▼   A signature of cosmic-ray increase in AD 774–775 from tree rings in Japan   Carbon-14 concentrations in tree rings are used as an indicator of cosmic ray activity — 14C is produced by the interaction of atmospheric nitrogen with cosmic-ray neutrons. Analysis of the 14C content of annual rings in two individual Japanese cedar trees covering the period AD 774 to 775 now reveals evidence of a rapid increase of about 12% in the 14C content, about 20-times larger than the change expected due to ordinary solar modulation. This suggests that an extremely energetic event occurred around AD 775 in our space environment, though its cause remains a mystery.       Podcast & Video     In this week's podcast: reading the minds of the brain dead, sequencing the last great ape, and fifty years since the book that sparked the green movement.         Special - Human MicrobiotaFree Access ▲top               Articles                   Structure, function and diversity of the healthy human microbiome ▶     Curtis Huttenhower, Dirk Gevers, Rob Knight, Sahar Abubucker, Jonathan H.

Macfarlan, Wesley D. Gifford, Shawn Driscoll, Karen Lettieri, Helen M. Rowe et al.     A rare cell subpopulation within mouse embryonic stem cell cultures is identified that exhibits properties of two-cell (2C) embryos; the interconversion of ES cells to 2C cells correlates with endogenous retroviral activity.             The bonobo genome compared with the chimpanzee and human genomes ▶     Kay Prüfer, Kasper Munch, Ines Hellmann, Keiko Akagi, Jason R. Miller et al.     Sequencing of the bonobo genome shows that more than three per cent of the human genome is more closely related to either the bonobo genome or the chimpanzee genome than those genomes are to each other.             Widespread adoption of Bt cotton and insecticide decrease promotes biocontrol services ▶     Yanhui Lu, Kongming Wu, Yuying Jiang, Yuyuan Guo & Nicolas Desneux     The widespread use of Bt crops reduces the outbreaks of certain targeted pests and the need for insecticide use, leading to enhanced biocontrol of other potential pest species in the Bt crops; neighbouring non-Bt crops may also benefit.             Emergence of KRAS mutations and acquired resistance to anti-EGFR therapy in colorectal cancer ▶     Sandra Misale, Rona Yaeger, Sebastijan Hobor, Elisa Scala, Manickam Janakiraman et al.     Molecular alterations in KRAS are associated with acquired resistance to anti-epidermal growth factor receptor (EGFR) treatment in colorectal cancer; resistant mutations can be identified in the blood of patients, months before clinical evidence of disease progression.             Analysis of Plasmodium falciparum diversity in natural infections by deep sequencing ▶     Magnus Manske, Olivo Miotto, Susana Campino, Sarah Auburn, Jacob Almagro-Garcia et al.     Next-generation sequencing is used here to analyse Plasmodium falciparum genome variation directly from clinical blood samples, as well as cultured isolates, from Africa, Asia and Oceania.             The molecular evolution of acquired resistance to targeted EGFR blockade in colorectal cancers ▶     Luis A. Diaz Jr, Richard T. Williams, Jian Wu, Isaac Kinde, J. Randolph Hecht et al.     This work on colorectal cancer shows that secondary mutations in KRAS that confer resistance to panitumumab, an anti-EGFR monoclonal antibody, are already present when antibody treatment begins; the apparent inevitability of resistance suggests that combinations of drugs targeting at least two different oncogenic pathway will be needed for treatment.             Dietary-fat-induced taurocholic acid promotes pathobiont expansion and colitis in Il10−/− mice ▶     Suzanne Devkota, Yunwei Wang, Mark W. Musch, Vanessa Leone, Hannah Fehlner-Peach et al.     Consumption of a diet high in milk-derived fat is shown to increase the abundance of sulphite-reducing bacteria by altering bile composition, leading to inflammation and colitis in genetically susceptible mice.             Drug discovery: Computer model predicts side effects ▶     Kyle Kolaja             Whole-genome analysis informs breast cancer response to aromatase inhibition ▶     Matthew J. Ellis, Li Ding, Dong Shen, Jingqin Luo, Vera J. Suman et al.     Whole-genome analysis of oestrogen-receptor-positive tumours in patients treated with aromatase inhibitors show that distinct phenotypes are associated with specific patterns of somatic mutations; however, most recurrent mutations are relatively infrequent so prospective clinical trials will require comprehensive sequencing and large study populations.             Large-scale prediction and testing of drug activity on side-effect targets ▶     Eugen Lounkine, Michael J. Keiser, Steven Whitebread, Dmitri Mikhailov, Jacques Hamon et al.     A large-scale computational effort is used to predict the activity of 656 drugs against 73 protein targets that have been associated with adverse drug reactions; the abdominal pain side effect of the synthetic oestrogen chlorotrianisene is shown to be mediated through its inhibition of cyclooxygenase-1.             A tumour suppressor network relying on the polyamine–hypusine axis ▶     Claudio Scuoppo, Cornelius Miething, Lisa Lindqvist, José Reyes, Cristian Ruse et al.     AMD1 and eIF5A are identified as two genes involved in the polyamine–hypusine pathway, a new tumour suppressor network regulating apoptosis.             Ecological opportunity and sexual selection together predict adaptive radiation ▶     Catherine E. Wagner, Luke J. Harmon & Ole Seehausen     Adaptive radiation of cichlid fishes in the African Great Lakes is predictable, but only when species traits and environmental factors are jointly considered.             SbsB structure and lattice reconstruction unveil Ca2+ triggered S-layer assembly ▶     Ekaterina Baranova, Rémi Fronzes, Abel Garcia-Pino, Nani Van Gerven, David Papapostolou et al.     Nanobody-aided X-ray crystallography and cryo-electron microscopy are used to describe the Ca2+-dependent polymerization dynamics of the S-layer of the Geobacillus stearothermophilus cell wall.             Articles and Letters                   Structure, function and diversity of the healthy human microbiome ▶     The Human Microbiome Project Consortium     The Human Microbiome Project Consortium reports the first results of their analysis of microbial communities from distinct, clinically relevant body habitats in a human cohort; the insights into the microbial communities of a healthy population lay foundations for future exploration of the epidemiology, ecology and translational applications of the human microbiome.             A framework for human microbiome research ▶     The Human Microbiome Project Consortium     The Human Microbiome Project Consortium has established a population-scale framework to study a variety of microbial communities that exist throughout the human body, enabling the generation of a range of quality-controlled data as well as community resources.             Human gut microbiome viewed across age and geography ▶     Tanya Yatsunenko, Federico E. Rey, Mark J. Manary, Indi Trehan, Maria Gloria Dominguez-Bello et al.     The human gut microbiome from a large cohort of more than 500 indivduals living on three continents with three distinct cultures is analysed, emphasizing the effect of host age, diet and environment on the composition and functional repertoire of fecal microbiota.             NPR3 and NPR4 are receptors for the immune signal salicylic acid in plants ▶     Zheng Qing Fu, Shunping Yan, Abdelaty Saleh, Wei Wang, James Ruble et al.     Plant resistance to pathogen challenge is thought to be mediated through salicylic acid (SA) signalling; here NPR3 and NPR4, paralogues of the transcription cofactor NPR1, are identified as receptors of SA.             A signature of cosmic-ray increase in AD 774–775 from tree rings in Japan ▶     Fusa Miyake, Kentaro Nagaya, Kimiaki Masuda & Toshio Nakamura     A rapid increase in the 14C content of Japanese cedar tree rings occurred during AD 774 to 775, and is about 20 times larger than the change attributed to ordinary solar modulation; neither a solar flare nor a local supernova is likely to have been responsible.             Acanthodes and shark-like conditions in the last common ancestor of modern gnathostomes ▶     Samuel P. Davis, John A. Finarelli & Michael I. Coates     New analysis of an Acanthodes braincase forces a reappraisal of the phylogeny of gnathosomes, suggesting that the vertebrate head underwent reorganization not only before the emergence of jaws, but also afterwards.             Covert skill learning in a cortical-basal ganglia circuit ▶     Jonathan D. Charlesworth, Timothy L. Warren & Michael S. Brainard     In Bengalese finches, a basal ganglia circuit, the anterior forebrain pathway, can covertly acquire the ability to adaptively modify song without contributing to song production during practice or training.             Autistic-like behaviours and hyperactivity in mice lacking ProSAP1/Shank2 ▶     Michael J. Schmeisser, Elodie Ey, Stephanie Wegener, Juergen Bockmann, A. Vanessa Stempel et al.     Altered glutamatergic neurotransmission can lead to the core symptoms of autism, and ProSAP1/Shank2 and ProSAP2/Shank3 proteins seem to serve different interrelated functions at excitatory synapses, especially in glutamate receptor targeting/assembly.             Autistic-like social behaviour in Shank2-mutant mice improved by restoring NMDA receptor function ▶     Hyejung Won, Hye-Ryeon Lee, Heon Yung Gee, Won Mah, Jae-Ick Kim et al.     Mutations in SHANK2 have been associated with autism spectrum disorders in humans; here, Shank2 mutant mice are shown to exhibit autistic-like behaviours that can be improved by restoring decreased NMDA receptor function.             The deubiquitinase USP9X suppresses pancreatic ductal adenocarcinoma ▶     Pedro A. Pérez-Mancera, Alistair G. Rust, Louise van der Weyden, Glen Kristiansen, Allen Li et al.     An in vivo transposon screen in a pancreatic cancer model identifies frequent inactivation of Usp9x; deletion of Usp9x cooperates with KrasG12D to accelerate rapidly pancreatic tumorigenesis in mice, validating their genetic interaction.             Control of a Salmonella virulence locus by an ATP-sensing leader messenger RNA ▶     Eun-Jin Lee & Eduardo A. Groisman     The Salmonella virulence gene mgtC is regulated by the levels of ATP through an ATP-sensing leader messenger RNA.             Atomic model of the type III secretion system needle ▶     Antoine Loquet, Nikolaos G. Sgourakis, Rashmi Gupta, Karin Giller, Dietmar Riedel et al.     The structure of the needle of the type III secretion system of Salmonella typhimurium, used to inject virulence proteins into host cells during infection, has been resolved by a combination of in vitro needle production, solid-state nuclear magnetic resonance, electron microscopy and Rosetta modelling at atomic resolution.             News & Views                   Microbiology: Learning about who we are ▶     David A.
