1997 - Dolly the Sheep

'We now report the birth of live lambs from three new cell populations established from adult mammary gland, fetus and embryo.' This issue of Nature (27 February, 1997) announces the arrival of lamb number 6LL3 or 'Dolly the Sheep', a break-through in cloning carried out at the Roslin Institute near Edinburgh.

In earlier centuries, advances in the sciences tended to be announced in books, such as Isaac Newton's Principia (gravity) or William Harvey's De motu cordis (circulation of the blood). But since the first publication of the journal Philosophical Transactions of the Royal Society in 1665, scientific periodicals have gradually taken over this role, and articles published in peer-reviewed journals are now the standard method of announcing scientific breakthroughs.
