| Creating the motion of nanosized or microsized objects is essential for building robots at small scales. Here, Uchida et al. move photoresponsive organic crystals on a glass substrate using two lamps, which crystallize and melt the crystal front and the rear, respectively, to generate the moving force. |

| Response to inflammatory stimuli such as endotoxin is coordinated at many levels. Here, the authors show that two microRNAs known to regulate inflammatory response inside the cell are secreted by dendritic cells and modulate inflammatory signalling in the neighbouring cells. |

| The extent to which the microbial carbon pump contributes to the generation of marine refractory dissolved organic matter (RDOM) remains a matter of debate. Here, the authors report results from a 3-year mesocosm study, and show that most of the microbial DOM is different from RDOM in the ocean. |

| Chromatin effector proteins often employ multivalent interactions with histone post-translational modifications. Here by using chemically defined nucleosome array and single-molecule microscopy, the authors show that effector multivalency prolongs chromatin retention and accelerates the association rate. |

| It has been proposed that the identification of genes regulating senescence in the absence of PTEN might help develop pro-senescence compounds for the treatment of cancer. Here, the authors use a combination of chemical and shRNA functional screen and identify CK2 as a potential target. |

| Organomagnesium reagents have been a staple for carbon–carbon bond formations for over a century, but are notoriously sensitive to water. Here, the authors show a Kumada-type coupling of aryl halides on water, with a potential intermediary of an in situ formed Grignard reagent. |

| Organocatalytic methods typically do not approach the extremely low loadings that can be achieved with some metal catalysed processes. Here, the authors report a remarkably powerful organocatalyst capable of performing asymmetric silylations with sub parts-per-million level loadings. |
