Not just a phase for RNAs

A phenomenon in which an RNA named NORAD drives a protein named Pumilio to form liquid droplets in cells, much like oil in water, appears to tightly regulate the activity of Pumilio. A new study led by UT Southwestern scientists ...

Exponential scaling of frictional forces in cells

AMOLF researchers have presented a theory that describes the friction between biological filaments that are crosslinked by proteins. Surprisingly, their theory predicts that the friction force scales highly nonlinearly with ...

Protein linked to cancer acts as a viscous glue in cell division

An over-abundance of the protein PRC1, which is essential to cell division, is a telltale sign in many cancer types, including prostate, ovarian, and breast cancer. New research, published online today in Developmental Cell, ...

Rainbow dyes add greater precision to fight against 'superbugs'

A study reported Feb. 17 in the journal Science led by researchers at Indiana University and Harvard University is the first to reveal in extreme detail the operation of the biochemical clockwork that drives cellular division ...

Protein structure reveals how cells regulate their skeletons

Insight into the regulation of cell skeleton structure has come from a study conducted by A*STAR researchers. The work, which solved a protein structure that has eluded scientists for 20 years, should lead to further insights ...

The two faces of cellular forgetfulness

Ludwig Maximilian University researchers have monitored how epigenetic information is transmitted to daughter cells during cell division and determined when the cell's developmental memory is re-established.
