A new method screens large libraries of synthetic cyclic peptides to identify compounds that can enter cells for therapeutic effect.

Using machine learning, researchers have tied low-magnitude microearthquakes to the permeability of subsurface rocks beneath the Earth, a discovery that could have implications for improving ...

Common ancestor eels lost the aquaporin gene encoding proteins with broad solute permeability. Researchers from the Institute of Science Tokyo have now found that recent gene duplication events in the ...

The bacterial envelope offers the first line of defence against antimicrobials. Understanding how bacteria control the entry and efflux of chemicals helps us to explain and possibly reverse ...
