Bacteria made to mimic cells, form communities

Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.

The structure and function of a controller of stem cell division

An important complex forming the core of the cell division apparatus in stem cells has been imaged using the Macromolecular Crystallography beamlines, I04 and I04-1 at Diamond Light Source. As recently reported in Nature ...

Oocytes: Going with the flow

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation for the highly ...

Live imaging puts new light on stem cell division

(PhysOrg.com) -- A long-held assumption about asymmetrical division of stem cells has cracked. Researchers at the University of Oregon report that the mitotic spindle does not act alone -- that cortical proteins help to position ...

Polarity proteins shape efficient 'breathing' pores in grasses

Grasses have "respiratory pores" (called stomata) that open and close to regulate the uptake of carbon dioxide for photosynthesis on the one hand and water loss through transpiration on the other. Unlike many other plants, ...
