Diversity in the lymphatic vasculature p.37

Precise control of localized signals p.38

The tumour-suppressor protein PTEN is mostly found in the cell cytoplasm, tethered to endosome vesicles. This localization regulates the enzyme's activity towards specific lipids and influences its control of cell growth.

A prefrontal–thalamo–hippocampal circuit for goal-directed spatial navigation p.50

Trajectory-dependent firing of neurons within the nucleus reuniens of the thalamus–hippocampus circuit predicted subsequent running direction, and disruption of this circuit reduced predictive firing in the hippocampus, suggesting that the thalamus is a key node in the integration of signals during goal-oriented navigation.

Lymphatic vessels arise from specialized angioblasts within a venous niche p.56

The lymphatic endothelium is thought to arise entirely from trans-differentiation of the venous endothelium; a new mechanism of lymphatic vessel formation is identified in zebrafish, whereby the lymphatic vessels derive from specialized angioblasts within the floor of the cardinal vein.

Cardiac lymphatics are heterogeneous in origin and respond to injury p.62

The lymphatic system is thought to be derived by transdifferentiation of venous endothelium; this study shows that the origin of cardiac lymphatics is in fact more heterogeneous, including both venous and non-venous origins and that lymphangiogenesis occurs in the adult heart following myocardial infarction and can be enhanced to improve heart function.

Observation of the rare Bs0µ+µ decay from the combined analysis of CMS and LHCb data OPEN p.68

The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested experimentally. The probabilities, or branching fractions, of the strange B meson () and the B0 meson decaying into two oppositely charged muons (μ+ and μ) are especially interesting because of their sensitivity to theories that extend the standard model. The standard model predicts that the and decays are very rare, with about four of the former occurring for every billion mesons produced, and one of the latter occurring for every ten billion B0 mesons. A difference in the observed branching fractions with respect to the predictions of the standard model would provide a direction in which the standard model should be extended. Before the Large Hadron Collider (LHC) at CERN started operating, no evidence for either decay mode had been found. Upper limits on the branching fractions were an order of magnitude above the standard model predictions. The CMS (Compact Muon Solenoid) and LHCb (Large Hadron Collider beauty) collaborations have performed a joint analysis of the data from proton–proton collisions that they collected in 2011 at a centre-of-mass energy of seven teraelectronvolts and in 2012 at eight teraelectronvolts. Here we report the first observation of the µ+µ decay, with a statistical significance exceeding six standard deviations, and the best measurement so far of its branching fraction. Furthermore, we obtained evidence for the µ+µ decay with a statistical significance of three standard deviations. Both measurements are statistically compatible with standard model predictions and allow stringent constraints to be placed on theories beyond the standard model. The LHC experiments will resume taking data in 2015, recording proton–proton collisions at a centre-of-mass energy of 13 teraelectronvolts, which will approximately double the production rates of and B0 mesons and lead to further improvements in the precision of these crucial tests of the standard model.

New cosmogenic burial ages for Sterkfontein Member 2 Australopithecus and Member 5 Oldowan p.85

Isochron burial dating with cosmogenic nuclides 26Al and 10Be shows that the skeleton of the australopithecine individual known as ‘Little Foot’ is around 3.67 million years old, coeval with early Australopithecus from East Africa; a manuport dated to 2.18 million years ago from the Oldowan tool assemblage conforms with the oldest age previously suggested by fauna.

Disruption of DNA-methylation-dependent long gene repression in Rett syndrome p.89

Rett syndrome is caused by mutation of the MECP2 gene that codes for a protein that binds methylated DNA; this study reveals that MeCP2 affects the expression of long genes, which often serve neuronal functions.

Eukaryotic initiation factor 3 (eIF3)—the deregulation of which has been linked with diverse cancers—is shown to bind to and direct the specialized translation of a subset of messenger RNAs, primarily involved in cell proliferation, differentiation and apoptosis, and can exert either translational activation or repression.
