How do the connections between a cell and its neighbours control how a cell responds? (FAULKNER_J27DTP) | Doctoral Training Partnership
Plant cells are connected to their neighbours via ‘tubes’ called plasmodesmata, creating an interconnected cytoplasm that joins cells within and between tissues and organs.

If life builds order from heterogeneity while never completely eliminating it, is heterogeneity merely a byproduct or could it be part of the means by which biological order is generated? Check out Lanxi Hu's review www.sciencedirect.com/science/arti...

ONLINE COVER
Maximum-intensity projection of a confocal image of epidermal cells from the Thale cress roots, where four colors stain different cell parts. 

Goldy et al. demonstrate that the protein actin allows cells to override standard division rules by stabilizing the orientation of spindles, which segregate chromosomes during mitosis. This uncovers a previously under-appreciated role for actin cytoskeletons, providing new insight into how division orientation is controlled to ensure robust tissue architecture during plant growth.

Translational research is digging for gold. Basic research is learning where and what to dig. The more funding is diverted to translation, the more we deplete the research ecosystem, driving the supplies of "gold" - immediately translatable findings and innovations - to unsustainably low levels.

It is sad that even basic research needs to be defended with utility. For me, basic research is in the same category as art: civilized societies can't do without it, because we all want to know who we are and what our place in the natural world is -- questions that only science can answer.
