Such a patchwork membrane likely arises from a combination of weak interactions between the diverse lipid and protein constituents of biological membranes. (biologie.uni-osnabrueck.de)
They discovered that attachment is probably mediated by multiple weak interactions, which could potentially be blocked by a combination of drugs or antibodies. (sciencedaily.com)
When the small instruments didn't detect any dark matter, scientists kept making them bigger, since larger instruments can detect weaker interactions. (insidescience.org)
