Where 1996 fits
Why 1996 is special
She was the first mammal cloned from an adult somatic cell, which had been widely considered impossible. She was named after Dolly Parton because the cell came from a mammary gland.
Same number, different meanings
How 1996 is understood across different contexts — never implying one meaning because of another.
- Mathematics
She was the first mammal cloned from an adult somatic cell, which had been widely considered impossible. She was named after Dolly Parton because the cell came from a mammary gland.
- Science
Dolly demonstrated that the nucleus of a fully differentiated adult cell could be reprogrammed to build a whole animal. That result, not the copying, is what changed developmental biology and led toward stem cell reprogramming.
- Technology & computing
RFC 1996 defines DNS NOTIFY, by which a primary server tells its secondaries that a zone has changed rather than waiting for them to poll on the refresh interval.
