Science communication

Summary

Science communication encompasses a wide range of activities that connect science and society. Common goals of science communication include informing non-experts about scientific findings, raising the public awareness of and interest in science, influencing people's attitudes and behaviors, informing public policy, and engaging with diverse communities to address societal problems. The term "science communication" generally refers to settings in which audiences are not experts on the scientific topic being discussed (outreach), though some authors categorize expert-to-expert communication ("inreach" such as publication in scientific journals) as a type of science communication. Examples of outreach include science journalism and health communication. Since science has political, moral, and legal implications, science communication can help bridge gaps between different stakeholders in public policy, industry, and civil society. Science communicators are a broad group of people: sc

MoleculARweb: A Web Site for Chemistry and Structural Biology Education through Interactive Augmented Reality out of the Box in Commodity Devices

Luciano Andres Abriata, Fabio Jose Cortes Rodriguez, Matteo Dal Peraro, Lucien Fabrice Krapp

Augmented/virtual realities (ARs/VRs) promise to revolutionize STEM education. However, most easy-to-use tools are limited to static visualizations, which limits the approachable content, whereas more interactive and dynamic alternatives require costly hardware, preventing large-scale use and evaluation of pedagogical effects. Here, we introduce https://MoleculARweb.epfl.ch, a free, open-source web site with interactive AR webpage-based apps that work out-of-the-box in laptops, tablets, and smartphones, where students and teachers can naturally handle virtual objects to explore molecular structure, reactivity, dynamics, and interactions, covering topics from inorganic, organic, and biological chemistry. With these web apps, teachers and science communicators can develop interactive material for their lessons and hands-on activities for their students and target public, in person or online, as we exemplify. Thousands of accesses to moleculARweb attest to the ease of use; teacher feedback attests to the utility in online teaching and homework during a pandemic; and in-class plus online surveys show that users find AR engaging and useful for teaching and learning chemistry. These observations support the potential of AR in future education and show the large impact that modern web technologies have in democratizing access to digital learning tools, providing the possibility to mass-test the pedagogical effect of these technologies in STEM education.

Distributed Compression in Acoustic Sensor Networks Using Oversampled A/D Conversion

Olivier Roy, Martin Vetterli

We address the problem of distributed compression in acoustic sensor networks. A typical scenario consists of a set of microphones that record a sound source located at some unknown position. The goal then is to convey the corresponding audio signals to a central base station for processing. We thus aim at designing efficient distributed communication schemes that minimize the overall bit-rate needed in order to achieve a given reconstruction accuracy. In this paper, we show how the a priori knowledge of the system's geometry can be beneficially used in order to lower the transmission rates. We propose a distributed coding scheme for simple synthetic sources. These results are then applied to more general signals by means of oversampled analog-to-digital conversion. Simulation results confirm the effectiveness of our approach.

From Becquerel To Nanotechnology: One Century Of Decline Of Scientific Dissemination, Publishing And Technology Transfer

Giorgio Margaritondo

2008 marks the 100th anniversary of Henri Becquerel's death, the discoverer of radioactivity and a leading contributor to the birth of modern physics. In addition to well-deserved celebrations, this offers a chance for a sobering look at scientific dissemination then and now and at the evolution of technology transfer. The facts are shocking: both dissemination and technology transfer were much faster and effective at the time of Becquerel, in spite of all the new communication techniques. I briefly speculate on the causes of these dismal failures, arguing that they are primarily rooted in society, academic management and industrial management - and therefore very difficult to reverse.
