Research into cell cycle regulation and size control in microorganisms has yielded a nuanced understanding of how these entities maintain homeostasis and synchronise growth with division. In both ...

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis ...

When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has ...

Doug Kellogg, professor of molecular, cell, and developmental biology at UC Santa Cruz, has been awarded $2.95 million from the National Institutes of Health (NIH) to study control of cell growth and ...

An active size-sensing mechanism may control the cell cycle in mammalian cells, according to a letter in Nature Cell Biology this week. A size threshold adjusts cell cycle length in the next cycle to ...

Trying to hit a target size before dividing seems like the best strategy for maintaining a precise cell size, but bacteria don't do that. Now we know why. When a single bacterial cell divides into two ...

During growth, cells must expand their cell volumes in coordination with biomass to control the level of cytoplasmic macromolecular crowding. Dry-mass density, the average ratio of dry mass to volume, ...

Petal size is a defining trait of ornamental flowers, directly shaping visual appeal and commercial value. A new study uncovers how petal expansion in roses is precisely regulated through a feedback ...
