“Using FRET-cAMP nanorulers, we directly map cAMP gradients at the nanoscale around PDE molecules and the areas of resulting downstream activation of cAMP-dependent protein kinase (PKA).” ...

Next, press G to grab the Gradient tool—this keyboard shortcut works in all three apps—and then choose a black-to-white, linear gradient. To do this in Photoshop, trot up to the Options bar ...

Noting that voltage gradient mapping has been proposed in adults to guide placement of ablation applications, Lindsey Malloy, DO, from the University of Iowa Children’s Hospital in Iowa City ...

Michael R. Willig, Christopher P. Bloch, Esa Ranta, Latitudinal Gradients of Species Richness: A Test of the Geographic Area Hypothesis at Two Ecological Scales ...

The study revealed a new mechanism whereby a gradient of retinoic acid (RA), a known morphogen, organizes the zebrafish vagus motor topographic map by coordinating chemoattractant signaling between ...
