Nature Podcast: 6 April 2017 This week, easing the pressure on fisheries, protein structure surprises, and your reading list for 2017 so far.
Podcast Extra - Grand Challenges: Mental health: Mental health disorders touch rich and poor, young and old, in every country around the world. Hear three experts discuss the evidence for interventions, how to get help to the right people, and which problem, if solved, would help the most.
Podcast Extra - Futures Futures is Nature's weekly science fiction slot. Shamini Bundell reads you her favourite from March, 'Green boughs will cover thee' by Sarah L Byrne.
BEATSON INTERNATIONAL CANCER CONFERENCE 'Feeding the Beast' – the Metabolic Landscape of the Tumour and its Host
2nd–5th July 2017, Glasgow
This meeting will provide a topical view of the metabolic vulnerabilities of cancer cells and how the interplay between tumour, stroma and systemic metabolism contributes to cancer progression and highlights opportunities for cancer treatment and prevention. Register here
Biocontrol: Crown-of-thorns no more The starfish Acanthaster planci destroys coral reefs. Whole- genome sequences provide clues to the proteins that mediate A. planci outbreaks — information that might be used to help protect coral.
Marine conservation: The race to fish slows down A fishery can allow participants to fish as hard as they can until its quota is reached, or allocate quota shares that can be caught at any time. A comparison of the systems in action reveals that shares slow the race to fish.
Structural biology: A receptor that might block itself The structure of the angiotensin II type 2 receptor reveals a potential mode of self-blocking action. This might explain its lack of signalling, and opens up avenues of investigation into its function and role in disease.
Materials Science: Screen printing of 2D semiconductors Atomically thin semiconductors have been made by transferring the oxide 'skin' of a liquid metal to substrates. This opens the way to the low-cost mass production of 2D semiconductors at the sizes needed for electronics applications.
Re-evaluation of learned information in Drosophila Depending on prediction accuracy at the time of memory recall, specific mushroom body output neurons drive different combinations of dopaminergic neurons to extinguish or reconsolidate appetitive memory in Drosophila.
Catch shares slow the race to fish A large-scale treatment–control meta-analysis of US fisheries provides evidence that the implementation of catch shares extend fishing seasons by slowing the race to fish.

Myeloid progenitor cluster formation drives emergency and leukaemic myelopoiesis During emergency myelopoiesis in mice, clusters of self-renewing granulocyte/macrophage progenitors (GMP) are transiently formed in the bone marrow cavity to produce a burst of myeloid cells; in leukaemia, GMP clusters persist and constantly generate myeloid leukaemia cells. Aurélie Hérault, Mikhail Binnewies, Stephanie Leong et al.
3D structures of individual mammalian genomes studied by single-cell Hi-C A chromosome conformation capture method in which single cells are first imaged and then processed enables intact genome folding to be studied at a scale of 100 kb, validated, and analysed to generate hypotheses about 3D genomic interactions and organisation. Tim J. Stevens, David Lando, Srinjan Basu et al.
Cerebellar granule cells encode the expectation of reward A sizable fraction of granule cells convey information about the expectation of reward, with different populations responding to reward delivery, anticipation and omission, with some responses evolving over time with learning. Mark J. Wagner, Tony Hyun Kim, Joan Savall et al.
A massive, quiescent galaxy at a redshift of 3.717 A massive ancient galaxy with minimal star formation is observed spectroscopically at an epoch when the Universe is less than 2 billion years old, posing a challenge to theories. Karl Glazebrook, Corentin Schreiber, Ivo Labbé et al.
Large historical growth in global terrestrial gross primary production Long-term records of global carbonyl sulfide levels reveal that terrestrial gross primary production (GPP) increased by around 30% during the twentieth century—a finding that may aid understanding of the connection between GPP growth and climate change. J. E. Campbell, J. A. Berry, U. Seibt et al.
