We have increasingly sophisticated ways of acquiring and communicating knowledge, yet, paradoxically, we are currently facing an unprecedented global ignorance crisis that affects our personal and societal well-being, as well as the stability of our democracies. There are two key triggers to this crisis, i.e. two crucial obstacles to learning: first, the widespread sharing of disinformation, which, in conjunction with an overly trusting audience, contributes to widely spread false beliefs, and correspondingly reckless political and social behaviour. At the same time, though, and at least as critical, is the prevalence of knowledge resistance and distrust in expertise. What we need to solve this high-stakes puzzle is a social epistemological framework that is able to explain the complex mechanisms underlying these surprising and unprecedented epistemic phenomena. This article will aim to sketch the contours of such a framework.

This article compares two different ways in which German industries, during the half century before 1914, managed to integrate useful results from scientific research: At the time, on the one hand there was single-firm-based industrial research, and on the other the cooperation of science, business, and government in the Emperor William Society for the Advancement of Sciences (1911) out of which, after the Second World War, the Max Planck Society emerged. On this basis, the article discusses similarities and tensions between capitalism and the sciences which, in spite of some structural similarities, follow different logics.

Infertility affects 10–15% of couples at the age of conception. Mounting evidence supports that not only are paternal factors crucial during fertilization, but also for embryogenesis. This review aims to provide some clues about the contribution of male factors to reproductive success and live birth, as such contributions can be as important as that of the female. Semen is composed of two fractions: sperm and seminal plasma. Regarding the former, the integrity of sperm components (i.e., centrioles, DNA integrity and methylation, histone-to-protamine ration, specific proteins, etc.) has been proven to be essential for some of the events occurring upon engulfment of the spermatozoon into the oocyte cytoplasm. The metabolic status of sperm also seems to shape their potential fertilizing capacity. Furthermore, seminal plasma appears to modulate the female reproductive tract, and has been suggested to support embryo implantation. In spite of the aforementioned, it remains largely unaddressed how paternal factors interact with maternal ones, and whether the latter may mask the former. While assisted reproductive techniques (ART) are useful to rescue infertility, a better understanding about the contribution of semen to fertilization, embryo development and implantation can increase the efficiency of these techniques, and address further the causes of total fertilization failure, implantation deficiency and recurrent miscarriage.

Legumes are a large and diverse family of plants that provide us with food, feed, fuel and feedstocks for industry. They can use atmospheric di-nitrogen for growth, via symbiotic nitrogen fixation (SNF) with bacteria called rhizobia, making them key to sustainable agricultural systems. There are opportunities to increase SNF in legumes to help tackle critical challenges related to the overuse of fertilizer nitrogen in agriculture. The last two decades have seen enormous progress in our understanding of the genetics of SNF, although this is yet to be leveraged to improve SNF in legumes. In principle, two main plant-based approaches exist to improve SNF, one involving genetic engineering and the other using existing natural variation in this complex trait. These approaches are not mutually exclusive and now is an opportune time to attempt to increase SNF in legumes via plant genetics and genomics.

Exploring the fundamental constituents of the matter around us and in the Universe, as well as their interactions, is among the premier goals of physics. Investigating ultrarelativistic collisions in particle accelerators has delivered answers to these questions many times in the past decades. In this article we focus on the research aimed at recreating the matter that filled the Universe in the first microsecond after the Big Bang – but this time in collisions of heavy ions. In particular, we discuss the technique called femtoscopy, which provides us with a tool to understand the space–time structure of particle creation in heavy-ion collisions. We use Lévy-stable distributions to investigate this structure and explore its dependence on particle momentum and collision energy.

Earth System Science stands as the future operating framework to monitor the pulse of the Earth, and to diagnose and address the challenges of global change. Magmatism and volcanism are primary processes connecting the solid Earth to the atmosphere, hydrosphere, and biosphere. In addition to regulating the Earth system, they are both an unavoidable source of hazards and a tremendous resource of energy and raw materials. Accessing magma is the necessary next step in the exploration of our planet. It will enable us to develop next-generation geothermal energy (magma energy), to transform volcano monitoring strategies, and perhaps even to alleviate volcanic activity. Recent exploratory geothermal drilling activities around the world have serendipitously encountered shallow magma bodies in the Earth. Following these remarkable magma drilling occurrences, the Krafla Magma Testbed (KMT) has been established in Iceland in order to create the first magma observatory – a world-class international in situ magma laboratory with access to the magma-rock-hydrothermal boundary through wells suitable for advanced studies and experiments. Here we review the importance of magma in the Earth system, present the multifaceted need for magma observatories and introduce the benefits of KMT as we enter a new generation of energy demands and resilience strategies.

Truth is a property of our statements and of our thoughts, but also what these aim at, and a norm for our thinking in general. But how to understand this normative tie between belief and truth? Norms by themselves seem unable to motivate or to guide us. These difficulties are stated, and the answer given is that the norm of belief is actually knowledge, which explains why we value it, and how it can also be a value.

In this article, I provide a brief account of my first decade of involvement in European science policy, of what I believe are the key structural issues in that landscape, and where I propose possible adjustments to address these issues.

This article reflects on whether and how European communities’ cultural frameworks of seasons are coming to poorly correspond to the climatic conditions they experience, and the implications for how Europe adapts to climatic (and social and environmental) change. It starts from a colder- and drier-than-normal autumn and winter (2023/2024) in Bergen, Norway, and a local researcher’s investigation into why these climatically anomalous seasons were being culturally celebrated as ‘seasonal weather’. He compares studies into the Bergen population’s cultural expectations for weather conditions in each of the four seasons, with the statistical climatic record, and reveals a mismatch. He argues that the four-season framework prominent in Europe poorly describes or anticipates meteorology in Bergen, and that other frameworks could fit better. The article argues that seasonal frameworks continuously evolve with interlinked environmental and social change – from drivers such as climate change, landscape modification, social evolution, and globalization – so that seasonal mismatches are as much about how societies culturally re-conceive of seasons as about physical climate change for instance. This is important because the way European societies divide the year by seasonal expectations affects how they relate to the meteorological conditions they come to face each season.
