Nature 16 April 2009 John Maddox 1925 -2009 In 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 charac teristically 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.

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. 16 January 2003 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.
How would you check a suspected clone’s DNA represents the credentials? blueprint of the human The two major uses for the information provided by DNA fingerprinting analysis are for personal identification and for the determination of paternity. 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). By Peter Artymiuk by nc nd 2. 0 UK: England & Wales 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. "DNA Fingerprint.

Flicker: dfarber Jurvetson He has also repeatedly supported genetic screening and genetic engineering in public lectures and interviews, arguing for instance that the "really stupid" bottom 10% of people should be aborted before birth; that all girls should be genetically engineered to be pretty [1] and has been quoted in The Sunday telegraph as stating "that if the gene (for homosexuality) were discovered and a woman decided not to give birth to a child that may have a tendency to become homosexual, she should be able to abort the fetus. " [2] The biologist Richard Dawkins wrote a letter to The Independentt claiming that Watson's position was misrepresented by The Sunday telegraph article and that Watson also considered the possibility of having a heterosexual child to be a valid reason for abortion. [3] Watson doesn't think much of the ambitiousness and energy of fat people, and is quoted as saying "Whenever you interview fat people, you feel bad, because you know you're not going to hire them" [4] He has also been attacked for justifying anti semitism, for advocating that certain racial, religious and ethnic groups' "numbers should be restricted", for claiming that blacks are genetically lazy and for advocating the infanticide of handicapped newborns[5].

The Human Genome Project (HGP) was an international scientific research project with a primary goal to determine the sequence of chemical base pairs which make up DNA and to identify the approximately 20, 000 25, 000 genes of the human genome from both a physical and functional standpoint. The project began in 1990 initially headed by James D. Watson at the U. S. National Institutes of Health. A working draft of the genome was released in 2000 and a complete one in 2003.

Erika Check reports. Erika Check Until a few weeks ago, a three-year-old boy whose identity remains confidential was a beacon of hope for gene therapists. He is one of 11 children with severe combined immune deficiency (SCID) to receive a pioneering treatment from a team led by Alain Fischer and Marina Cavazzana-Calvo of the Necker Hospital for Sick Children in Paris. It worked, providing the first proof that gene therapy can cure a life-threatening disease 1. Now, however, the boy has developed a leukaemia-like condition that most experts believe was caused by the very treatment that cured his SCID. … Nature 420, 116 118 (14 November 2002) | doi: 10. 1038/420116 a

A clash of two cultures Nature 445, 603 (8 February 2007) Evelyn Fox Keller 1 Evelyn Fox Keller is at the Massachusetts Institute of Technology, Abstract Physicists come from a tradition of looking for all-encompassing laws, but is the best approach to use when probing complex biological systems? Biologists often pay little attention to debates in the philosophy of science. But one question that has concerned philosophers is rapidly coming to have direct relevance to researchers in the life sciences: are there laws of biology? That is, does biology have laws of its own that are universally applicable? Or are the physical sciences the exclusive domain of such laws? Today, biologists are faced with an avalanche of data, made available by the successes of genomics and by the development of instruments that track biological processes in unprecedented detail. To unpack how proteins, genes and metabolites operate as components of complex networks, modelling and other quantitative tools that are well established in the physical sciences — as well as the involvement of physical scientists — are fast becoming an essential part of biological practice. Accordingly, questions about just how much specificity needs to be included in these models, about where simplifying assumptions is appropriate, and about when (if ever) the search for laws of biology is useful, have acquired pragmatic importance — even some urgency.

Biology's next revolution Nigel Goldenfeld 1 & Carl Woese 2 Abstract The emerging picture of microbes as gene-swapping collectives demands a revision of such concepts as organism, species and evolution itself. One of the most fundamental patterns of scientific discovery is the revolution in thought that accompanies a new body of data. Satellite based astronomy has, during the past decade, overthrown our most cherished ideas of cosmology, especially those relating to the size, dynamics and composition of the Universe. Similarly, the convergence of fresh theoretical ideas in evolution and the coming avalanche of genomic data will profoundly alter our understanding of the biosphere — and is likely to lead to revision of concepts such as species, organism and evolution. Here we explain why we foresee such a dramatic transformation, and why we believe the molecular reductionism that dominated twentieth century biology will be superseded by an interdisciplinary approach that embraces collective phenomena.

News and Views Nature 450, 803 804 (6 December 2007) | doi: 10. 1038/nature 06363; Published online 18 November 2007 Cancer: Immune pact with the enemy Cornelis J. M. Melief Abstract Progress comes from the latest investigations into a long standing question in immunology — the role of the immune system in maintaining small, potentially cancerous lesions in a state of dormancy. The current belief about treating cancer is that tumour cells need to be eradicated as quickly as possible, so as to halt tumour growth and spread, and to prevent or delay the death of the patient. The startling results of Koebel et al. 1 (page 903 of this issue) demonstrate that considering cancer as a fatal disease is not always appropriate*. The authors show in mice that induction of cancer by methylcholanthrene (MCA), a tar component of the kind found in cigarette smoke, causes an initial wave of deadly tumours affecting many animals, after which the surviving mice show no evidence of growing tumours. Deceptively, however, dormant tumours still exist in these apparently healthy mice, and these are kept in check by the immune system. This state can be fatally disrupted by suppression of the immune system, allowing the dormant tumours to wrest themselves from immune control and grow, spread and kill their host.
