We review the status and future of direct searches for light dark matter. We start by answering the question: "Whatever happened to the light dark matter anomalies?" i.e. the fate of the potential dark matter signals observed by the CoGeNT, CRESST-II, CDMS-Si and DAMA/LIBRA experiments. We discuss how the excess events in the first two of these experiments have been explained by previously underestimated backgrounds. For DAMA, we summarize the progress and future of mundane explanations for the annual modulation reported in its event rate. Concerning the future of direct detection, we focus on the irreducible background from solar neutrinos. We explain broadly how it will affect future searches and summarize efforts to mitigate its effects.

A mirror sector of particles and forces provides a simple explanation of the inferred dark matter of the Universe. The status of this theory is reviewed - with emphasis on how the theory explains the impressive DAMA/NaI annual modulation signal, whilst also being consistent with the null results of the other direct detection experiments.

Abstract In his strategic political positioning and engagement in the nineteenth century, Groen van Prinsterer looked towards both the past and the future. Rhetorically, he appealed to the past as a vindication of the truth and practicality of his anti-revolutionary position. He also expressed optimism for the success of his convictions and political goals in the future. This optimism was reflected in the confidence with which he engaged politically, despite experiencing numerous setbacks in his career. Relying on the phenomenological-narrative approach of David Carr, I highlight the motives and strategies behind Groen’s political activity, and reveal that the past and the future in Groen’s narrative provide the strategic framework for his rhetoric, and the basis for his activism. I accentuate how the emphasis of his narrative shifts away from the status quo and thus enables a type of political engagement that proved historically significant for the early consolidation of the Dutch constitutional democracy.

I consider models of light super-weakly interacting cold dark matter, with [Formula: see text] mass, focusing on bosonic candidates such as pseudoscalars and vectors. I analyze the cosmological abundance, the γ-background created by particle decays, the impact on stellar processes due to cooling, and the direct detection capabilities in order to identify classes of models that pass all the constraints. In certain models, variants of photoelectric (or axioelectric) absorption of dark matter in direct-detection experiments can provide a sensitivity to the superweak couplings to the Standard Model which is superior to all existing indirect constraints. In all models studied, the annual modulation of the direct-detection signal is at the currently unobservable level of O(10-5).

I’ve been teaching since 1973, some in area schools, some in intermediates, but mostly in secondary schools. Throughout my career I have enjoyed studying part-time, and in 2004 I was privileged to spend the year as an e-Fellow. I’m still studying, still reflecting on education in general and teaching in particular, and still very interested in what it means to be working in this space, what it means to be a teacher. In this piece I am therefore writing primarily with my colleagues in mind—I am writing for the classroom practitioners of today who are the teachers of the future. The ideas of connectedness and collaboration that I discuss here are based on what I have learned from my own practice. Built on a firm theoretical foundation, they represent my synthesis of education wisdom and philosophy. They are intended to challenge the status quo and to provoke change, just as the future challenges us to learn from the past but move from the present.

Similar to the 1960s, higher education is once again in a period of rapid social chance in which new demands and expectations are being made on colleges and universities. This time, however, new money is not available for the transition to be achieved though additional growth. In this paper, the methodology of Position Description Analysis is presented using Dalhousie University as a case study. Position Description Analysis is a tool for assessing the discrepancy between the status quo and the specializations needed for colleges and universities to meet the new demands and expectations which are being made of them. It is concluded that there is a need for dramatic realignement of fields of specialization in order to shift from the emphases of the past to those of the future. However, because the faculty higher in the 1960s are now tenure, but no due to retire until after the year 2000, higher education must find internal strategies for chance or face externally imposed solution to their current lack of flexibility.

This introductory essay reviews the history of the Journal, divided into two stages: the period from 1921 to 1953; and that from 1954 to today. It examines the changing institutional arrangements, personnel, as well as some of the highlights in the content of the Journal. If there is a theme, it is that the Journal was established by and developed its reputation because of the efforts of many of the outstanding scholars at Cambridge who over the decades offered the outputs of their talents to the Journal; and that the Journal has used that reputation more and more to attract the scholars outside Cambridge – indeed from all over the world. Whatever the aims of those who established the Cambridge Law Journal in 1921, and without much self-consciousness, the Journal incrementally acquired the status and practices of a learned journal. Finally, the essay reflects on the future, in particular the challenges of digitisation, open access and inclusivity.

Background. Monoclonal antibodies with high efficiency and specificity are one of the best strategies to diagnose and treat a variety of diseases such as cancer, autoimmunity, and inflammatory diseases. The market for monoclonal therapeutic antibodies (MTAs) has grown dramatically in the past decade. Objective. Given the importance of these issues, developing countries spend a high cost on importing or producing MTAs annually. This study intends to examine the market of monoclonal therapeutic antibodies in Iran and predict the future growth rate of this market using the obtained data. Methods. Data on the status of MTAs in the country (from 2008 to 2018) were obtained from the Food and Drug Deputy of Mazandaran University of Medical Sciences. The market status of MTAs was studied based on the dosage forms, application, and price. Then, the market outlook was predicted up to year 2025. Results. The results showed that 58.8% of all MTAs were humanized, and 86% of all antibody-based drugs were used to treat cancer. Sales of MTA-based medications will reach $454 million by 2025 and are projected to grow significantly in the future. Conclusion. Given the increasing technology of the production of MTAs and their use in targeted therapies worldwide, their consumption market in Iran is expected to grow significantly.

The nature of dark matter is one of the most fundamental scientific unknowns. Particle physicists have spent decades searching for evidence of dark matter particles. The PandaX project is a staged xenon-based dark matter direct detection experiment located at the China Jinping Underground Laboratory. In this paper, we give an overview of the PandaX experiment, discuss its recent scientific results, and outline the plan for the future.
