We found that the transcription factor Hey supervises the identity of differentiated enterocytes (ECs) in the adult Drosophila midgut. Lineage tracing established that Hey-deficient ECs are unable to maintain their unique nuclear organization and identity. To supervise cell identity, Hey determines the expression of nuclear lamins, switching from a stem-cell lamin configuration to a differentiated lamin configuration. Moreover, continued Hey expression is required to conserve large-scale nuclear organization. During aging, Hey levels decline, and EC identity and gut homeostasis are impaired, including pathological reprograming and compromised gut integrity. These phenotypes are highly similar to those observed upon acute targeting of Hey or perturbation of lamin expression in ECs in young adults. Indeed, aging phenotypes were suppressed by continued expression of Hey in ECs, suggesting that a Hey-lamin network *For correspondence: safeguards nuclear organization and differentiated cell identity.

Discovery of DNA Structure and Function: Watson and Crick By: Leslie A
01/08/2018 Discovery of DNA Double Helix: Watson and Crick | Learn Science at Scitable NUCLEIC ACID STRUCTURE AND FUNCTION | Lead Editor: Bob Moss Discovery of DNA Structure and Function: Watson and Crick By: Leslie A. Pray, Ph.D. © 2008 Nature Education Citation: Pray, L. (2008) Discovery of DNA structure and function: Watson and Crick. Nature Education 1(1):100 The landmark ideas of Watson and Crick relied heavily on the work of other scientists. What did the duo actually discover? Aa Aa Aa Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher's discovery, other scientists--notably, Phoebus Levene and Erwin Chargaff--carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix. The First Piece of the Puzzle: Miescher Discovers DNA Although few people realize it, 1869 was a landmark year in genetic research, because it was the year in which Swiss physiological chemist Friedrich Miescher first identified what he called "nuclein" inside the nuclei of human white blood cells. (The term "nuclein" was later changed to "nucleic acid" and eventually to "deoxyribonucleic acid," or "DNA.") Miescher's plan was to isolate and characterize not the nuclein (which nobody at that time realized existed) but instead the protein components of leukocytes (white blood cells). -
Frederick Alt of Harvard University and Boston Children's Hospital
PRESS RELEASE Frederick Alt of Harvard University and Boston Children’s Hospital Awarded 2015 Szent-Györgyi Prize for Progress in Cancer Research (Bethesda, MD – February 26, 2015) The National Foundation for Cancer Research (NFCR) announced today that Frederick Alt, Ph.D., Professor of Genetics at Harvard Medical School, Director of the Program in Cellular and Molecular Medicine at Boston Children’s Hospital, and Howard Hughes Medical Institute Investigator has been awarded the 2015 Szent-Györgyi Prize for Progress in Cancer Research. Dr. Alt’s groundbreaking work in cancer genetics over four decades has helped to shape the very roots of modern cancer research. Today, that work continues to bear fruit, profoundly impacting the approaches that doctors use to diagnose and treat cancer. NFCR’s selection committee was unanimous in its decision to recognize Dr. Alt, whose work has proved foundational to the modern understanding of cancer – not only how the lethal disease forms, but also how it can become resistant to treatment. In particular, his seminal discoveries of gene amplification and his pioneering work on molecular mechanisms of DNA damage repair have helped to usher in the era of genetically-targeted therapy and personalized medicine. “Dr. Alt has been a consistently outstanding scientist throughout his career, and this award recognizes his entire body of work,” said Dr. James Allison, Executive Director of the Immunotherapy Platform at MD Anderson Cancer Center, winner of the 2014 Szent-Györgyi Prize, and Chair of this year’s Prize Selection Committee. “The genetic processes he described are central to understanding the mechanisms that cause cancer, and have ultimately led to an entire class of targeted therapy and associated diagnos- tics that are providing benefit to countless cancer patients.” Dr. -

Interpreting the History of Evolutionary Biology Through a Kuhnian Prism: Sense Or Nonsense?
Interpreting the History of Evolutionary Biology through a Kuhnian Prism: Sense or Nonsense? Koen B. Tanghe Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Lieven Pauwels Department of Criminology, Criminal Law and Social Law, Universiteit Gent, Belgium Alexis De Tiège Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Johan Braeckman Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Traditionally, Thomas S. Kuhn’s The Structure of Scientific Revolutions (1962) is largely identified with his analysis of the structure of scientific revo- lutions. Here, we contribute to a minority tradition in the Kuhn literature by interpreting the history of evolutionary biology through the prism of the entire historical developmental model of sciences that he elaborates in The Structure. This research not only reveals a certain match between this model and the history of evolutionary biology but, more importantly, also sheds new light on several episodes in that history, and particularly on the publication of Charles Darwin’s On the Origin of Species (1859), the construction of the modern evolutionary synthesis, the chronic discontent with it, and the latest expression of that discon- tent, called the extended evolutionary synthesis. Lastly, we also explain why this kind of analysis hasn’t been done before. We would like to thank two anonymous reviewers for their constructive review, as well as the editor Alex Levine.

Quiet Debut'' of the Double Helix: a Bibliometric and Methodological
Journal of the History of Biology Ó Springer 2009 DOI 10.1007/s10739-009-9183-2 Revisiting the ‘‘Quiet Debut’’ of the Double Helix: A Bibliometric and Methodological note on the ‘‘Impact’’ of Scientific Publications YVES GINGRAS De´partement d’histoire Universite´ du Que´bec a` Montre´al C.P. 8888, Suc. Centre-Ville Montreal, QC H3C-3P8 Canada E-mail: [email protected] Abstract. The object of this paper is two-fold: first, to show that contrary to what seem to have become a widely accepted view among historians of biology, the famous 1953 first Nature paper of Watson and Crick on the structure of DNA was widely cited – as compared to the average paper of the time – on a continuous basis from the very year of its publication and over the period 1953–1970 and that the citations came from a wide array of scientific journals. A systematic analysis of the bibliometric data thus shows that Watson’s and Crick’s paper did in fact have immediate and long term impact if we define ‘‘impact’’ in terms of comparative citations with other papers of the time. In this precise sense it did not fall into ‘‘relative oblivion’’ in the scientific community. The second aim of this paper is to show, using the case of the reception of the Watson–Crick and Jacob–Monod papers as concrete examples, how large scale bibliometric data can be used in a sophisticated manner to provide information about the dynamic of the scientific field as a whole instead of limiting the analysis to a few major actors and generalizing the result to the whole community without further ado. -
