  • In 1976, it was demonstrated that tiny wobbles in Earth's orbit led to the great ice-age cycles of the past few million years. This finding had wide implications for climate science and the details remain hotly debated today.

  • Plaque deposits often occur in curved arterial regions with turbulent blood flow. Endothelial cells have been found to respond to blood flow through a previously unidentified signalling pathway that affects plaque build-up. See Letter p.579

  • Global sea levels would rise by several metres if the Greenland Ice Sheet melted completely. Two studies have examined its past behaviour in an effort to evaluate its vulnerability in a warming world — and have come to seemingly conflicting conclusions. Two geochemists and a glaciologist discuss the issues. See Letters p.252 & p.256

  • Viruses can be attacked by parasitic viruses, which compete with them for cellular resources. It emerges that one such parasitic virus can defend a host-cell population from a viral attack. See Letter p.288

  • Structures of two chemokine receptor proteins in complex with small molecules reveal a previously unknown binding pocket that could be a drug target for treating a range of diseases involving this receptor family. See Letters p.458 & p.462

  • Can simple genetic risk profiles be identified for complex diseases? The development of a gene-expression profile for acute myeloid leukaemia suggests that they can, and that they may improve prognosis prediction. See Letter p.433

  • The chemical composition of a massive galaxy in the early Universe reveals an extremely short period of star formation. This result could challenge our ideas about the evolution of galaxies and of the Universe itself. See Letter p.248

  • High-resolution satellite mapping of Earth's surface water during the past 32 years reveals changes in the planet's water systems, including the influence of natural cycles and human activities. See Letter p.418

  • Electrical oscillations generated by neural circuits are disrupted in Alzheimer's disease. Restoring these oscillations in mouse models activates immune cells to clear disease-associated amyloid-β protein from the brain. See Article p.230

  • Quantum technology enables new methods for generating of randomness with minimal assumptions, certified by the violation of a Bell inequality, which opens up new theoretical and experimental research directions and leads to new challenges.

  • This Review discusses current knowledge of the structure, function and interactions of the metabotropic glutamate and GABAB receptors and the potential to target receptor subunits for future therapeutic intervention in neurological and mental health disorders.

  • A comprehensive review into mammalian interspecies chimaeras, documenting the advances that have occurred alongside developments in stem-cell biology and assessing the future of the field, including any possible ethical and legal issues.

  • Nuclear DNA from human eggs that harbour mutations in the DNA of organelles called mitochondria has been successfully transferred to donor eggs, bringing the prospect of therapy for mitochondrial diseases a step closer. See Letter p.270

  • Changes in the amount of carbon stored in soil might be a crucial feedback to climate change. Experimental field studies show that warming-induced soil carbon losses are greatest where carbon stocks are largest. See Letter p.104

  • Activation of aged muscle stem cells induces changes in DNA packaging that lead to expression of the gene Hoxa9. This reactivates embryonic signalling pathways, restricting the cells' ability to repair injured muscle. See Letter p.428

  • Retinal-cell transplants restore vision in mouse models of retinal degeneration. It emerges that the transplant leads to an exchange of material between donor and host cells — not to donor-cell integration into the retina, as had been presumed.

  • Studies of a large frost-filled basin on Pluto show that this feature altered the dwarf planet's spin axis, driving tectonic activity on its surface, and hint at the presence of a subsurface ocean. See Letters p.86, p.90, p.94 & p.97

  • Human stem cells that can give rise to every cell type in the body are major players in biomedical research. A molecular analysis of human embryos might help to make these cultured cells more authentic imitations of their in vivo counterparts.

  • To reach the cell surface, membrane proteins are first targeted to an organelle called the endoplasmic reticulum. Several targeting pathways are known, but it now emerges that there is yet another pathway. See Letter p.134

  • Wild and managed pollinators are threatened by pressures such as environmental changes and pesticides, leading to risks for pollinator-dependent crop production, meaning more research and better policies are needed to safeguard pollinators and their services.
