| | Cancer: Double trouble for tumours
When some cancer cells delete a tumour-suppressor gene, they also delete nearby genes. It emerges that one of these latter genes has a key metabolic role, revealing a therapeutic opportunity that might be relevant for many tumours. | Virology: Phages make a group decision
It emerges that phage viruses, which infect bacteria, use small peptides to communicate with each other. This observation of intercellular communication also reveals how viruses make a key developmental decision. | Materials science: Versatile gel assembly on a chip
Materials called hydrogels have potential applications as scaffolds for tissue engineering, but methods are needed to assemble them into complex structures that mimic those found in nature. Just such a method has now been reported. | IL-17 is a neuromodulator of Caenorhabditis elegans sensory responses
Interleukin-17 functions as a neuromodulator in the roundworm Caenorhabditis elegans, acting directly on RMG hub interneurons to alter their response properties and contribution to behaviour. | Structure of a eukaryotic cyclic-nucleotide-gated channel
The first high-resolution (3.5 Å) structure of a full-length cyclic-nucleotide-gated channel, revealing an unconventional, voltage-insensitive voltage-sensor domain and a unique coupling mechanism between cyclic-nucleotide-binding and pore-opening. | Neurotoxic reactive astrocytes are induced by activated microglia
A reactive astrocyte subtype termed A1 is induced after injury or disease of the central nervous system and subsequently promotes the death of neurons and oligodendrocytes. | Communication between viruses guides lysis–lysogeny decisions
Some phages—viruses that infect bacteria—encode peptides that are secreted from infected cells and that, beyond a certain threshold, stimulate other viruses to switch from the lytic (killing the host cell) to lysogenic (dormant) phase. | Compensatory water effects link yearly global land CO2 sink changes to temperature
A study of how temperature and water availability fluctuations affect the carbon balance of land ecosystems reveals different controls on local and global scales, implying that spatial climate covariation drives the global carbon cycle response. | Ultrafast nonthermal photo-magnetic recording in a transparent medium
Ultrafast photo-magnetic recording in transparent films of the dielectric cobalt-substituted garnet has very low heat load and is much faster than existing alternatives. | The ligand Sas and its receptor PTP10D drive tumour-suppressive cell competition
Wild-type Drosophila epithelial cells outcompete proto-oncogenic cells through translocation of the ligand Sas to the wild-type–tumour cell interface, where it binds the PTP10D receptor of the tumour cell, initiating pro-apoptotic signalling. | Genomic deletion of malic enzyme 2 confers collateral lethality in pancreatic cancer
Depletion of malic enzyme 3 in pancreatic cancer cells that have a deletion of the gene for malic enzyme 2 selectively kills the cells, suggesting that the enzyme might represent a therapeutic target for this subset of cancers. | Evolutionary genomics of the cold-adapted diatom Fragilariopsis cylindrus OPEN
The genome of the Southern Ocean phytoplankton Fragilariopsis cylindrus differs markedly from the genomes of its more temperate relatives, with divergent alleles being differentially expressed in environmentally specific conditions such as freezing and darkness. | | Corrigendum: Structural basis of N6-adenosine methylation by the METTL3–METTL14 complex | | Frontiers in biology

A robust and scale-independent strategy for the design of reconfigurable architected materials (in which properties are adjusted by altering structure rather than composition) is described, based on space-filling assemblies of polyhedra.
Johannes T. B. Overvelde, James C. Weaver, Chuck Hoberman et al. | Genomic hallmarks of localized, non-indolent prostate cancer
Genomic analyses of localized, non-indolent prostate cancer identify recurrent aberrations that can predict relapse, and also highlight differences between early prostate cancer and metastatic, castration-resistant disease.
Michael Fraser, Veronica Y. Sabelnykova, Takafumi N. Yamaguchi et al. | Reversible methylation of m6Am in the 5′ cap controls mRNA stability
Fat mass and obesity-associated protein (FTO) preferentially demethylates m6Am, a modified adenosine that, when present at the 5′ end of certain mRNAs, positively influences mRNA stability by preventing DCP2-mediated decapping.

In general, if there are fewer Atlantic hurricanes, those near the US coast are more likely to intensify, whereas if there are many hurricanes, then those near the coast are more likely to weaken because of high local wind shear and low sea surface temperatures.
