    Description: One hundred and fifty years ago this week, on 10 April 1861, the Massachusetts Institute of Technology (MIT) received its charter. Although hardly the oldest institution of higher learning in the Anglo-American world — Harvard University was already well into its third century by then, and the British universities of Cambridge and Oxford were each on the cusp of their eighth — MIT quickly became a trendsetter. Founder William Barton Rogers built a curriculum around the school's motto Mens et manus: mind and hand. He and his faculty members incorporated laboratory instruction into the most elementary undergraduate courses and fostered close ties between basic science and the practical arts — pedagogical innovations that quickly inspired many imitators.

    Description: Bacteria often practice autoinduction, in which a molecule released and reabsorbed by the same cell adjusts genetic expression according to local density of signalling cells. Autoinducers, first noticed in luminescent bacteria, were identified in Agrobacterium tumefaciens by Margaret More.

    Description: Understanding the behavior of the universe at large depends critically on insights about the smallest units of matter and their fundamental interactions. Inflationary cosmology is a highly successful framework for exploring these interconnections between particle physics and gravitation. Inflation makes several predictions about the present state of the universe-such as its overall shape, large-scale smoothness, and smaller scale structure-which are being tested to unprecedented accuracy by a new generation of astronomical measurements. The agreement between these predictions and the latest observations is extremely promising. Meanwhile, physicists are busy trying to understand inflation's ultimate implications for the nature of matter, energy, and spacetime.

    Description: The History of Science Society meeting from November 15 to 18, 2012 featured 318 speakers and commentators, and it tackled topics such as the circulation of knowledge and science in international context. Participants were allowed to comment on Twitter, and history references to the Cold War became popular.

    Description: Though the notion of a scientific textbook has been around for almost three centuries, the category has hardly been stable. The plasticity of the textbook genre may be illustrated by recent variations as well as long-term trends. In this brief essay I examine two idiosyncratic but highly successful physics books, each published in the mid 1970s, whose production, marketing, and adoption reveal some of the slippage between such categories as textbook, scholarly monograph, and popular best seller.

    Description: Historians of recent science face a daunting challenge of scale. Local case studies—our principal means of interrogating past scientific practices—fail to capture the sweep and texture of some of the most dramatic changes in scientific life since World War II. During that period, most facets of research grew exponentially, from numbers of practitioners to numbers of research articles published in any given specialty. The explosive growth placed unprecedented pressure on the intellectual coherence of various disciplines. Drawing on examples from the postwar physics profession in the United States, I suggest that simple quantitative methods can aid in elucidating patterns that cut across isolated case studies, suggesting themes and questions that can guide close, archival research.

    Description: Circadian rhythms pre-adapt the physiology of most organisms to predictable daily changes in the environment. Some marine organisms also show endogenous circalunar rhythms. The genetic basis of the circalunar clock and its interaction with the circadian clock is unknown. Both clocks can be studied in the marine midge Clunio marinus (Chironomidae, Diptera), as different populations have different local adaptations in their lunar and diurnal rhythms of adult emergence, which can be analyzed by crossing experiments. We investigated the genetic basis of population variation in clock properties by constructing the first genetic linkage map for this species, and performing quantitative trait locus (QTL) analysis on variation in both lunar and diurnal timing. The genome has a genetic length of 167–193 centimorgans based on a linkage map using 344 markers, and a physical size of 95–140 megabases estimated by flow cytometry. Mapping the sex determining locus shows that females are the heterogametic sex, unlike most other Chironomidae. We identified two QTL each for lunar emergence time and diurnal emergence time. The distribution of QTL confirms a previously hypothesized genetic basis to a correlation of lunar and diurnal emergence times in natural populations. Mapping of clock genes and light receptors identified ciliary opsin 2 ( cOps2 ) as a candidate to be involved in both lunar and diurnal timing; cryptochrome 1 ( cry1 ) as a candidate gene for lunar timing; and two timeless ( tim2, tim3 ) genes as candidate genes for diurnal timing. This QTL analysis of lunar rhythmicity, the first in any species, provides a unique entree into the molecular analysis of the lunar clock.

    Description: Abstract Commentators have often complained about specialization in the history of science. This essay discusses recent intellectual trends within our discipline in the light of significant changes in graduate training: both a relatively recent consensus as to the types of sources that are appropriate to analyze in a dissertation and the tremendous growth in the number of new dissertations completed each year in our field. It suggests that this kind of focus on pedagogical concerns provides useful analytic tools for historians investigating other fields in various times and places.
