TL;DR: International law on the protection of children in armed conflict lacks a single source, but the 1989 UN Convention on the Rights of the Child is a key treaty in this field.
Abstract: Abstract THERE IS NO SINGLE SOURCE for the international law of the child, which means it must be looked for in specific and general treaties, in the broad field of human rights at both universal and regional levels, in the rules of international humanitarian law, in customary international law and in the law and practice of States. In 1924, the League of Nations adopted the first declaration on the rights of the child, stressing the need for special care and protection. Though followed by a series of similar and related declarations,1 another sixty-five years were to pass before the international community acknowledged the very special status of children, and the desirability of States entering into a treaty on their behalf. The 1989 UN Convention on the Rights of the Child, already ratified by some 144 States, is rightly recognized as a critical milestone in the legal protection of children.
TL;DR: Sure, here is the TLDR: Southern blotting and Northern blotting techniques were developed in 1975 and 1976, respectively, and revolutionized molecular biology.
Abstract: Abstract In 1975 Southern published his method for the identification of specific DNA fragments which had been resolved by gel electrophoresis via transfer of the band pattern to nitrocellulose membrane filters (1). This technique immediately gained recognition, proving to be a milestone in molecular biology, and has since been referred to as Southern blotting. It was not long thereafter that a new technique was developed in which the macromolecule to be analysed was RNA, also immobilized to a filter matrix; this technique was coined Northern blotting (2).
