Benjamin Falcon, Wenjuan Zhang, Alexey G. Murzin et al. | Protein complexes assemble as they are being made
An investigation finds that most protein complexes in yeast cells assemble before the subunits have fully formed. This mechanism might prevent the formation of toxic protein aggregates.

The crystal structure of anion channelrhodopsin-1 (ACR1) from the algae Guillardia theta provides insights into the basis of anion conductance.
Yoon Seok Kim, Hideaki E. Kato, Keitaro Yamashita et al. | Ancient herders enriched and restructured African grasslands
Isotopic and sedimentary analyses of soils at Pastoral Neolithic archaeological sites in Kenya demonstrate the long-term influence of nutrient enrichment on savannah environments that has accompanied pastoralist settlement over the past three millennia.
Fiona Marshall, Rachel E. B. Reid, Steven Goldstein et al. | Spotlight on proteins that aid malaria
The multiprotein complex PTEX enables malaria-causing parasites to survive inside red blood cells. Studies reveal how PTEX assembles, and identify a function for one of the complex’s proteins, EXP2.
Tania F. de Koning-Ward | The NORAD lncRNA assembles a topoisomerase complex critical for genome stability
The long non-coding RNA NORAD interacts with proteins involved in DNA replication and repair, and controls the ability of RBMX to form a ribonucleoprotein complex that helps to maintain genomic stability.
Mathias Munschauer, Celina T. Nguyen, Klara Sirokman et al. | Malaria parasite translocon structure and mechanism of effector export
Cryo-electron microscopy analysis of the purified Plasmodium translocon of exported proteins (PTEX) reveals two distinct resolved states, suggesting a mechanism by which Plasmodium falciparum exports malarial effector proteins into erythrocytes.
Chi-Min Ho, Josh R. Beck, Mason Lai et al. | All-inorganic perovskite nanocrystal scintillators
All-inorganic perovskite nanocrystals containing caesium and lead provide low-cost, flexible and solution-processable scintillators that are highly sensitive to X-ray irradiation and emit radioluminescence that is colour-tunable across the visible spectrum.
Qiushui Chen, Jing Wu, Xiangyu Ou et al. | Past experience shapes sexually dimorphic neuronal wiring through monoaminergic signalling
In Caenorhabditis elegans, starvation early in life suppresses later sex-specific pruning of synapses through lasting changes in monoaminergic signalling.
