Plants communicate with neighbouring plants to activate an airborne defence against aphids. However, the genetic pathway underlying this defence mechanism is unknown. A signalling cascade centred around the gaseous form of the chemical methyl salicylate was found to control this interaction between plants.
Some countries are rushing to roll out autumn COVID-19 vaccination campaigns. Plus, why Morocco’s earthquake was so deadly and how lab leaders in the UK are grappling with a lack of postdocs.
The United Nations has ambitious aims to end poverty and clean up the planet by 2030. See whether you know how the world is faring on the Sustainable Development Goals.
A wide range of harmful bacteria introduce proteins into plant cells. Some of these proteins move to the cell membrane and serve as channels for water and nutrients, creating favourable conditions for bacterial growth beside plant cells.
Tumour cells tend to migrate to the vertebrae rather than to long bones, but the mechanism underlying this has been unclear. It emerges that the stem cells from which vertebrae are derived make a factor that attracts tumour cells.
The molecular mechanism underlying the severe neurogenic inflammation induced by Clostridioides difficile is presented, providing a therapeutic target for treating this infection.
A study reports the three-dimensional structure of the Ebola virus polymerase in complex with VP35 and RNA, and reveals features required for initiation of viral replication.
The obscuration of light from a distant galaxy has raised the possibility that a type of carbon dust existed in the earliest epochs of the Universe — challenging the idea that stars had not yet evolved enough to make such material.
