Spider glue is actually a specialized silk protein.
The glue that gives spider webs their stickiness is a form of spider silk protein. Researchers can imagine cool uses for a synthetic version – but had to wait for the tricky glue gene to be sequenced.
Antibiotic resistance can spread between microbes within hours.
Resistance to antibiotics is not a new trait, and it is impossible to prevent. But it is possible to avoid its spread.
