The COVID-19 pandemic forced physicians around the world to make tragic decisions: Whose life should be saved when it is apparent that available resources are insufficient to treat everyone? Under the heading of "triage" a broad societal debate ensued that also ignited the scientific community. This anthology unites voices from medicine, law, and philosophy for a conversation. It reveals controversies that are deeply rooted in ideas of law, morality, and the role of the individual in the state. Simultaneously, answers are being formulated to questions that have become sadly prominent in the COVID pandemic but could also valid beyond it.

Abortions represent one of the most controversial issues in contemporary society. Some states have adopted restrictive legislation on interruption of pregnancy to diminish the number of abortions performed annually. Other states have adopted abortion-on-demand rules guaranteeing women free access to abortions. Based on the statistical dates, the problem of interruption of pregnancy remains a crucial one and requires prompt action undertaken by the state. This article is dedicated to the analysis of measures undertaken by the state to reduce the number of abortions and stimulate population growth. This study highlights the effectiveness of remedies taken by some states, e.g. the USA, and presents a multitude of measures that states regulated in national law.

AbstractIn medicine and other academic settings, (doctoral) students often work in interdisciplinary teams together with researchers of pharmaceutical sciences, natural sciences in general, or biostatistics. They should be fundamentally taught good research practices, especially in terms of statistical analysis. This includes reproducibility as a central aspect. Acknowledging that even experienced researchers and supervisors might be unfamiliar with necessary aspects of a perfectly reproducible workflow, a lecture series on reproducible research (RR) was developed for young scientists in clinical pharmacology. The pilot series highlighted definitions of RR, reasons for RR, potential merits of RR, and ways to work accordingly. In trying to actually reproduce a published analysis, several practical obstacles arose. In this article, reproduction of a working example is commented to emphasize the manifold facets of RR, to provide possible explanations for difficulties and solutions, and to argue that harmonized curricula for (quantitative) clinical researchers should include RR principles. These experiences should raise awareness among educators and students, supervisors and young scientists. RR working habits are not only beneficial for ourselves or our students, but also for other researchers within an institution, for scientific partners, for the scientific community, and eventually for the public profiting from research findings.

With assistance of the APSA, the political science members of the National Academy of Sciences (NAS) held their standing meeting at the annual APSA convention in Chicago. The purposes of these meetings are two-fold: First, as required, to discuss ways that political science can fulfill the NAS mission in providing scientific evidence to address consequential public issues that come from queries posed by various agencies of government; and second, to increase the presence of political scientists in the Academy, where membership from our discipline is, in our view, much lower than political scientists' contributions to the scientific community, and does not adequately recognize the many political scientists who merit election. While we have made some progress toward this second goal, it is a complicated battle: 2,179 members and 437 foreign associates across scientific disciplines have been elected to and currently serve in the NAS, but only 21 are political scientists. Although the science-based mission of NAS does not seek to represent all of the highly pluralistic discipline of political science, far more research relying on methods that are recognized in the natural sciences is produced in our field than is presently represented in the NAS.

Abstract It is necessary to consider the factors affecting the dynamics and blood glucose (BG) level to maintain a horse’s high performance and health during intensive training. The study aimed to research the influence of the feeding regime on the change in BG level in the Orlov trotter horses during the period of intensive training (summer) in the conditions of the stud farm’s training center in the Kaluga region (Russia). Horses aged 2 to 4 years, stallions (n = 7), and mares (n = 5) received commercial mixed feed three times a day and grass hay in free access. Four times a week after lunch, horses are released into the paddock with cut grass. Blood was collected from the jugular vein. Blood was collected before morning feeding and then every hour until four h after morning and afternoon feeding. The dynamics of BG changes depending on the presence or absence of the grass paddock after feeding were evaluated. If horses remained in the stall after feeding, the BG level gradually increased, reaching a maximum (4.95 ± 0.21 mmol/L) 3 hours after feeding and was significantly higher (P ≤ 0.05) than when they were immediately moved to the paddock with grass. The maximum BG concentration in horses in the paddock was observed 1 hour after feeding (4.55 ± 0.21 mmol/L); it didn’t have significant differences with the BG level after 1 hour in “stall horses” (4.5 ± 0.14 mmol/L). Then the BG level of the “paddock horses” gradually decreased, and in the “stall horses” increased. No significant difference in BG levels was observed 4 hours after feeding. When horses can walk in a paddock after feeding concentrates and eat grass, blood glucose levels do not rise and tend to decrease.

We introduce some of the 96 books of scientific content, published in the 16th century and belonging to the Istituto Lombardo library. We chose some books in the field of the “natural sciences” both for iconographic peculiarities and for the original content. The library owns the first edition of the anatomy treatise of Andrea Vesalio. The medical books of Jean Francois Fernel, Antonio Fracanzani, Girolamo Fracastoro, the botanical treatise of Pier Andrea Mattioli and the geographical treatise of Giovan Battista Ramusio although in further edition are of great interest in order to evaluate the state of the art and the evolutionary steps of the science. Some books are rather rare and precious and deserve to be accurately exploited. Also the texts should be worthy of a critical investigation, overcoming the linguistic difficulties, both for the latin and for italian texts.

In the 1980s, the Chinese state pushed the Chinese Academy of Sciences (CAS) to establish businesses. Some of these businesses did not engage in any research and development (R&D), and this resulted in scientists having concerns about the boundary around the institutionalizing scientific community. When the state supported CAS’s ‘Knowledge Innovation’ reform in the late 1990s, CAS’s organizing principle became centered on a more narrowly scientific logic, which led to less reliance on business income. Regression analysis indicates that CAS-owned enterprises without R&D were more likely to be discontinued during ‘Knowledge Innovation’. Moreover, businesses having no R&D were more likely to be discontinued (1) if they were making high profits and (2) if they were supervised by an institute in which Academicians had longer tenure, because these conditions heightened science-market conflict.
