What if cellular signaling pathways work better than we thought? Previous experiments were population-level measurements, but using optogenetics, we can determine the information capacity of the ERK pathway for single cells.

Single Cells Can Resolve Graded Stimuli
By quantifying the information transmitted from receptor to ERK, the study shows that individual cells can resolve graded stimuli, transmitting over 2 bits of information even with brief, sparse input...

Scientists could obtain more information from two measurements of a biochemical network if they analyze them collectively, rather than sequentially. Story by me. Written for @physicsmagazine.bsky.social. physics.aps.org/articles/v16...
More Informative Together Than Apart
The concurrent analysis of two measurements of a biochemical signaling network can provide more information than two separate probes of the datasets.
