Drawn together

From flocks of birds to molecular motors, active-matter systems are made up of individual units that each consume energy from their surroundings and convert it into mechanical work. Experimental demonstrations of such systems have been widely explored for their abilities to spontaneously form patterns and generate flows. But synthetic systems usually lack the level of spatiotemporal control seen in biological systems. In this week’s issue, Tyler Ross, Matt Thomson and their colleagues show that light can be used to guide the behaviour of an engineered active-matter system, giving rise to a suite of emergent structures and properties that can be dynamically manipulated and controlled. The cover shows the microtubules that form the basis of their system. Associated with these tubules are molecular motors (orange) that walk along the tubules. These motors form dimers under light, which can then pull the tubules towards each other, allowing the researchers to control the emergent structures.

    Superconducting magnets have been used to trap cold oxygen molecules and study their collisions. This method could lead to a better understanding of low-temperature interactions for a broad range of molecules.

    Cells compete for survival during development. It emerges that mammalian cells on a path to form a tumour express specific versions of the protein Flower when they vie for survival with surrounding normal cells.

    Stressed yeast cells take up the amino acid lysine and reprogram their metabolism to free up supplies of a stress-relieving molecule. Lysine uptake therefore increases the tolerance of yeast cells to stress.

    An analysis of aquifer replenishment in sub-Saharan Africa shows that reduced precipitation does not always deplete groundwater reserves, challenging the idea that these reserves will decrease in response to global warming.

    Accurate estimates of the biodiversity of soil animals are essential for conservation efforts and to understand the animals’ role in carbon cycles. Such information is now available on a global scale for nematode worms.

    Species of the eukaryotic phylum Rhodelphidia are non-photosynthetic, flagellate predators with gene-rich genomes, in contrast to their closely related sister lineage—the red algae—which are immotile, typically photoautotrophic and have relatively small intron-poor genomes and reduced metabolism.

    The harvest of large quantities of lysine by yeast and other microbes triggers a reprogramming of redox metabolism, in which NADPH is channelled into glutathione metabolism to reduce levels of reactive oxygen species and increase tolerance to oxidative stress.
