From the critically acclaimed author of Oblivion comes Year of the Comet, a story of a Russian boyhood and coming of age as the Soviet Union is on the brink of collapse. An idyllic childhood takes a sinister turn. Rumours of a serial killer haunt the neighbourhood, families pack up and leave town without a word of warning, and the country begins to unravel. Policemen stand by as protesters overtake the streets, knowing that the once awe-inspiring symbols of power they wear on their helmets have become devoid of meaning. Lebedev depicts a vast empire coming apart at the seams, transforming a very public moment into something tender and personal, and writes with stunning beauty and shattering insight about childhood and the growing consciousness of a boy in the world.

By means of this ‘Frontiers in Genetics’ research topic, we are celebrating 30 years of the Comet Assay. The first paper on this single-cell gel electrophoresis assay was published in 1984 by O. Ostling and K.J. Johanson (Biochem. Biophys. Res. Commun. Vol.123: 291-298). The comet assay is a versatile and sensitive method for measuring single - and double-strand breaks in DNA. By including lesion-specific enzymes in the assay, its range and sensitivity are greatly increased, but it is important to bear in mind that their specificity is not absolute. The comet assay (with and without inclusion of lesion-specific enzymes) is widely used as a biomarker assay in human population studies - primarily to measure DNA damage, but increasingly also to assess the capacity of cells for DNA repair. Ostling and Johanson (Biochem. Biophys. Res. Commun., 1984) were also the first to report experiments to measure DNA repair, by simply following the decrease of DNA damage over time after challenging cells with ionising radiation. However, this approach is time-consuming and laborious as it requires an extended period of cell culture and is therefore not ideal for biomonitoring studies, which typically require high-throughput processing of many samples. As an alternative approach, the in vitro comet-based repair assay was developed: a cell extract is incubated with a DNA substrate containing specific lesions, and DNA incisions accumulate. The in vitro comet-based repair assay has been modified and improved over the past decade: it was first devised to measure base excision repair of oxidised purines in lymphocytes (Collins et al., Mutagenesis, 2001), but has since been adapted for other lesions and thus other repair pathways, as well as being applied to tissue samples in addition to cell suspensions. Even after 30 years, the comet assay is still in a growth phase, with many new users each year. Many questions are repeatedly raised, which may seem to have self-evident answers, but clearly, it is necessary to reiterate them for the benefit of the new audience, and sometimes being forced to think again about old topics can shed new light. Different applications of the comet assay are discussed in this special issue, including: genotoxicity testing in different organisms, human biomonitoring, DNA repair studies, environmental biomonitoring and clinical studies. Furthermore, we consider and where possible answer questions, including the ones raised by Raymond Tice at the 8th International Comet Assay Workshop in Perugia (Italy 2009): What is the spectrum of DNA damage detected by the various versions of the comet assay?; What are the limitations associated with each application?; What should be done to standardize the assay for biomonitoring studies?; Can the comet assay be used to monitor changes in global methylation status?; What cell types are suitable for detecting genotoxic substances and their effects in vivo and in vitro?; Can the assay be fully automated?; and more. So this ‘Frontiers in Genetics’ research topic is written for the beginner as well as for the experienced users of the comet assay.

This is H. G. Wells' 1906 science fiction novel, "In the Days of the Comet". The strange vapours of a nearby comet begin to alter the air of Earth itself, engendering an incredible, long-lasting transformation in the way people think. An entertaining and thought-provoking novel, "In the Days of the Comet" represents the classic sci-fi that Wells is famous for, and it is not to be missed by fans and collectors of his seminal work. Herbert George Wells (1866 - 1946) was a prolific English writer who wrote in a variety of genres, including the novel, politics, history, and social commentary. Today, he is perhaps best remembered for his contributions to the science fiction genre thanks to such novels as "The Time Machine" (1895), "The Invisible Man" (1897), and "The War of the Worlds" (1898). Although never a winner, Wells was nominated for the Nobel Prize in Literature a total of four times. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this book now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author. First published in 1906.
