Things Jolie needs to do before she bites it
\"Jolie's a lot of things, but she knows that pretty isn't one of them. She has mandibular prognathism, which is the medical term for underbite. Chewing is a pain, headaches are a common occurrence, and she's never been kissed. She's months out from having a procedure to correct her underbite, and she cannot wait to be fixed. Jolie becomes paralyzed with the fear that she could die under the knife. She and her best friends, Evelyn and Derek, decide to make a \"Things Jolie Needs to Do Before She Bites It (Which Is Super Unlikely, but Still, It Could Happen)\" list. Things like: eat every appetizer on the Applebee's menu and kiss her crush Noah Reed. But since when did everything ever go exactly to plan? Filled with humor, heart--and an honest look at today's beauty standards--Jolie's journey is a true feel-good story\"--Jacket flap.

Self-powered perovskite photon-counting detectors
Metal-halide perovskites (MHPs) have been successfully exploited for converting photons to charges or vice versa in applications of solar cells, light-emitting diodes and solar fuels

, for which all these applications involve strong light. Here we show that self-powered polycrystalline perovskite photodetectors can rival the commercial silicon photomultipliers (SiPMs) for photon counting. The photon-counting capability of perovskite photon-counting detectors (PCDs) is mainly determined by shallow traps, despite that deep traps also limit charge-collection efficiency. Two shallow traps with energy depth of 5.8 ± 0.8 millielectronvolts (meV) and 57.2 ± 0.1 meV are identified in polycrystalline methylammonium lead triiodide, which mainly stay at grain boundaries and the surface, respectively. We show that these shallow traps can be reduced by grain-size enhancement and surface passivation using diphenyl sulfide, respectively. It greatly suppresses dark count rate (DCR) from >20,000 counts per second per square millimetre (cps mm

) to 2 cps mm

at room temperature, enabling much better response to weak light than SiPMs. The perovskite PCDs can collect γ-ray spectra with better energy resolution than SiPMs and maintain performance at high temperatures up to 85 °C. The zero-bias operation of perovskite detectors enables no drift of noise and detection property. This study opens a new application of photon counting for perovskites that uses their unique defect properties.
Suppression of shallow traps responsible for dark count rates in polycrystalline methylammonium lead triiodide using diphenyl sulfide enables the production of metal-halide perovskite photon-counting detectors that allow sensitive detection of γ-ray spectra.

The Designer's Corner - How Was Issue 2071 Made?
When Polimac first spoke with David about \"The Journey to 2071\" the topic sounded very attractive, but at the same time it felt quite intimidating, for two reasons. First, what can they really expect from the future? And second, how should she visualizes it and put it on paper? After sometime pondering and doing research, and receiving great input from David, Siobhan and Ishani, the ideas started sprouting. She looked into contemporary visions of their future, and even though their outlook seems pretty grim, an inkling of hope is still present. In the end, that was a unique vision of their team - it will not be easy, but if they work on it together, they can win and march toward a brighter future. Just like their writers imagined in their articles, she started his illustrations with yellow and orange (the beginning of problems), continued with red (the world burning) and finished with green and white (the new beginning).

What Is Citizen Science? – A Scientometric Meta-Analysis
The concept of citizen science (CS) is currently referred to by many actors inside and outside science and research. Several descriptions of this purportedly new approach of science are often heard in connection with large datasets and the possibilities of mobilizing crowds outside science to assists with observations and classifications. However, other accounts refer to CS as a way of democratizing science, aiding concerned communities in creating data to influence policy and as a way of promoting political decision processes involving environment and health.
In this study we analyse two datasets (N = 1935, N = 633) retrieved from the Web of Science (WoS) with the aim of giving a scientometric description of what the concept of CS entails. We account for its development over time, and what strands of research that has adopted CS and give an assessment of what scientific output has been achieved in CS-related projects. To attain this, scientometric methods have been combined with qualitative approaches to render more precise search terms.
Results indicate that there are three main focal points of CS. The largest is composed of research on biology, conservation and ecology, and utilizes CS mainly as a methodology of collecting and classifying data. A second strand of research has emerged through geographic information research, where citizens participate in the collection of geographic data. Thirdly, there is a line of research relating to the social sciences and epidemiology, which studies and facilitates public participation in relation to environmental issues and health. In terms of scientific output, the largest body of articles are to be found in biology and conservation research. In absolute numbers, the amount of publications generated by CS is low (N = 1935), but over the past decade a new and very productive line of CS based on digital platforms has emerged for the collection and classification of data.

A Problem-Based Approach to Democratic Theory
Over the last few decades, democratic theory has grown dramatically in its power and sophistication, fueled by debates among models of democracy. But these debates are increasingly unproductive. Model-based strategies encourage theorists to overgeneralize the place and functions of ideal typical features of democracy, such as deliberation or elections. Here I sketch an alternative strategy based on the question: What kinds of problems does a political system need to solve to count as “democratic”? I suggest three general kinds: it should empower inclusions, form collective agendas and wills, and have capacities to make collective decisions. We can view common practices such as voting and deliberating as means for addressing these problems, and theorize institutional mixes of practices that would maximize a political system's democratic problem-solving capacities. The resulting theories will be both normatively robust and sufficiently fine-grained to frame democratic problems, possibilities, and deficits in complex polities.

Politicizing International Cooperation: The Mass Public, Political Entrepreneurs, and Political Opportunity Structures
International institutions are increasingly being challenged by domestic opposition and nationalist political forces. Yet, levels of politicization differ significantly across countries facing the same international authority as well as within countries over time. This raises the question of when and why the mass public poses a challenge to international cooperation. In this article, we develop a theoretical framework for understanding the nature and implications of politicization of international cooperation, outlining three scope conditions: the nature of public contestation, the activities of political entrepreneurs, and the permissiveness of political opportunity structures. By empirically examining these scope conditions, we demonstrate that politicization can have both stabilizing and destabilizing effects on international cooperation. Highlighting the systemic implications of politicization for international cooperation has important implications for international relations scholarship. Although international organizations may face challenges, they also have ways of being remarkably resilient.
