a) A classical morphogen (pink) elicits differential gene expression (represented by the black, red and blue bars) by activating different genes at different concentrations. b) One example of such a ...

As the gradient decays, the position of this threshold value moves at varying speed along the membrane, depending on the cell shape. Thus, via this hierarchy of protein concentration profiles, the ...

In a ground-breaking study, researchers report a new technique that allows them to visualize the distribution of retinoic acid in a live zebrafish embryo, in real-time. This technique enabled them to ...

Scientists designed autonomous nanovesicles capable of following glucose concentration gradients, even through the blood brain barrier in rats. A series of rodent experiments showed that even with ...

Scientists use tools called gradients to understand how molecules interact in biological systems. Researchers have developed a new technique for creating biomolecular gradients that is both simpler ...

Composition-gradient multi-angle light scattering (CG-MALS) is a biophysical technique that can be used to measure the self-association of macromolecules in solution. This technique allows fast, ...

Understanding the evaporation process of binary sessile droplets is essential for optimizing various technical processes, such as inkjet printing or heat transfer. Liquid mixtures whose evaporation ...

Scientists have developed a novel approach that can help create safer and long-lasting lithium-ion batteries. Combined with an automated reactor system, the mathematical x-framework allows unlimited ...

1. Wild bees are one of the most important groups of pollinators in the temperate zone. Therefore, population declines have potentially negative impacts for both crop and wildflower pollination.
