Nature16 April 2009 John Maddox 1925-2009In memory of a transformative editor of Nature • It was with great sadness that I and my colleagues at Nature learned of the death on Sunday of Sir John Maddox — or 'JM', as hiscolleagues always referred to him. • ……….. • …………….. • It was during his first stint that he laid the foundations for Nature as it is today. Importantly (JM liked to start sentences with adverbs), he threw aside the highly informal and somewhat crony-based system for selecting papers and established a system of peer review. A characteristically readable account of this can be found in his valedictory Essay in his last issue (see Nature 378, 521–523; 1995). • This move was not without his own reservations — he liked to say that the 1953 paper on the structure of DNA would never have passed peer review. He never lost his distrust of such refereeing as an obstacle to the truly original, and occasionally dispensed with it altogether during his first stint as editor.

The Second Creation: Dolly and the Age of Biological Control
First cloned human due 2002 ? Dolly and human cloning
The first human clone: The team from Advanced Cell Technology. Massachusetts hope that one day stem cells cloned from a patient’s cells could be used to treat their illnesses. Proud American geneticists have announced the world’s first cloned human embryo. By coaxing egg cells to divide without adding sperm, they created all- female embryos. But all six eggs that divided into cloned embryos died after a few days. The scientists claim they are aiming to create disease-busting stem cell, not a cloned baby. 27 November 2001
First human clone – or is it? 2003 started with a baby boom and claims that a handful of New Year newborns are the first human clones. Scientists are skeptical, saying the wannabe cloners have made it look too easy. Cloning has a poor track record. Of the ten types of animal they’ve tried to clone so far, only six have produced live young using the technique that created Dolly the sheep. 16 January 2003
How would you check a suspected clone’s credentials? DNA represents the blueprint of the human genetic makeup. It exists in virtually every cell of the human body and differs in its sequence of nucleotides (molecules that make up DNA, also abbreviated by letters, A, T, G, C). The two major uses for the information provided by DNA-fingerprinting analysis are for personal identification and for the determination of paternity. The complete DNA of each individual is unique, with the exception of identical twins. A DNA fingerprint, therefore, is a DNA pattern that has a unique sequence such that it can be distinguished from the DNA patterns of other individuals. DNA fingerprinting is also called DNA typing. The human genome is made up of 3 billion nucleotides, which are 99.9% identical from one person to the next. The 0.1% variation, therefore, can be used to distinguish one individual from another. It is this difference that can be used by forensic scientists to match specimens of blood , tissue, or hair follicles to an individual with a high level of certainty.
