Foreign disinformation is a matter of significant concern in democracies. While the empirical evidence of its influence is more nuanced than many threat perceptions suggest, uncertainty in crucial domains complicates decision-making. An analysis of these uncertainties highlights the importance of fostering civil trust and maintaining proportionality in policies and discourse around disinformation.

The threat posed by potential attacks using biological (B) or chemical (C) weapons is real, and it is being exacerbated by the security situation. This requires states to enhance their preparedness, response, and investigation capabilities in the case of incidents involving these weapons. In this CSS Analysis Sophie Reiners states that reliable investigative mechanisms are necessary, with forensic methods playing a key role.

When it comes to getting along together, trust plays an indispensable role. While we all have an intuitive grasp of what this interpersonal investment involves, even science struggles to express exactly how it works.

In our new study published in the Proceedings of the National Academy of Science (PNAS), we describe a microRNA-based mechanism that coordinates the scaling of inhibitory and excitatory synapses during homeostatic plasticity, with possible implications for sleep regulation. Colameo et al., PNAS 2025 Apr 8;122(14):e2500880122. doi: 10.1073/pnas.2500880122.

Circular RNAs are a recently discovered class of non-coding RNAs and are highly expressed in mammalian neurons. In a new study published in Nature Communications, Kelly et al. identified a circular RNA which controls the formation of silent synapses, dormant neural connections that can be activated for memory formation. These findings increase our understanding of the molecular mechanisms underlying synaptic plasticity and memory.

Trust takes years to build and seconds to break – not least when it comes to international relations. ETH researchers investigate what it takes to build confidence on the global stage.

A global ranking of the research productivity of political science departments puts the CIS at the top of European departments per number of faculty members. 

Trust in AI models is about more than just technical performance – ethical principles and human values are equally important.

This workshop report written by several CSS experts summarizes the discussions and insights from a workshop organized by the Center for Security Studies. The event convened international experts in technology and economic security, alongside public and private sector practitioners, to assess risks and explore strategies for enhancing European resilience in global semiconductor supply chains.

ISTP Doctoral Candidate Florian Lichtin successfully defended his PhD thesis

In conversation with Fritz Brugger, Beatrice Maser Mallor discusses how the World Bank is adapting to address both poverty reduction and climate change. 

Strategic Trends, the annual flagship publication of the Center for Security Studies (CSS) at ETH Zurich, examines in 2025 the pivotal forces and developments shaping global security, offering critical analysis of the challenges and opportunities in a world undergoing profound transformation.

Sport has reemerged as a tool for autocratic states to strengthen their legitimacy domestically and internationally. Qatar and Saudi Arabia, in particular, have invested heavily in sport and positioned state-linked figures in international sport organizations. Fabio Schmocker concludes in this CSS Analysis that while this strategy has increased the Gulf states’ global visibility, it has also drawn more attention to human rights issues.

A deepening rift in transatlantic relations has reignited debates on how to strengthen nuclear deterrence in Europe in the absence of credible US security guarantees. No exact alternatives exist or would even be desirable. In her CSS analysis, Névine Schepers argues that opportunities for enhanced strategic dialogue and cooperation with willing European allies could instead provide some reassurance and may shape further changes in doctrine and force posture in the long-term.

Katrin Sievert was named one of the top 30 young scientists working on climate change

How does disinformation impact public trust in science? And can healthy scepticism be a good thing? A debate between climate researcher Sonia Seneviratne, communication scientist Mike S. Schäfer and former Swiss Federal Chancellor Walter Thurnherr.

She is named one of the top 30 young scientists in the world working on climate change.

Meet Yilin Huang, a recent graduate of the STP Master’s program. She began her studies in autumn 2021, minoring in Resources and Environment. Before beginning her Master’s, she completed a bachelor’s degree in materials engineering from the University of Toronto, in Canada. In this interview, Yilin shares her experience during an internship at the United Nations, where she worked with the Office for Disarmament Affairs (UNODA).

A new study by NADEL’s Professor Isabel Günther, Dr Kenneth Harttgen, and Dr Dario Meili from ETH Zurich’s Development Economics Group reveals that traditional measures of gender and ethnic disparities overlook key inequalities in education. 

Unipolar and bipolar depression are often misdiagnosed, hampering medical treatment. In a recent paper published in EMBO Reports, we describe a microRNA signature in human peripheral blood which distinguishes bipolar from unipolar depression patients. Studies in mice further revealed an important function of these microRNAs in the brain. Our results could pave the way towards the translation of microRNA biomarkers to clinical practice in psychiatry.

Invited talk “Inequality by design: Music streaming taxonomies as ruinous infrastructure” by Raquel Campos Valverde (University of Leeds), 2025-03-11, 10:30, ETH Zurich, Social Networks Lab, room WEP H 11.

In a new edition of the CSS Policy Perspectives, Fabian Hofmann describes the ethical challenges associated with digital peacebuilding. He argues that Switzerland can take a leading role in establishing ethical standards for AI in peace and conflict resolution.

NADEL's Dr Kenneth Harttgen has co-authored a new paper on anemia risk among children and women in sub-Saharan Africa.

The ISTP is looking for a new team member for its Communication Activities!

In this newly published book, negotiators and scholars join forces to identify how ceasefires and political negotiations intersect and when and how ceasefires work to promote peace. Case studies cover conflicts in Bosnia, Burundi, Colombia, Darfur, El Salvador, Myanmar, the Philippines, Sudan North/South, and Syria.

Congratulations to both Erwin Lefoll and Leopold Peiseler on successfully defending their PhD theses!

Switzerland has been actively involved in military peace support in the Western Balkans since the 1990s. It has gradually taken on more responsibility and is now respected, both locally and internationally, as a security producer. Despite the improved security situation, geopolitics and poor governance make political solutions difficult to achieve. A continued presence remains in Switzerland’s interests.

Europe faces geopolitical challenges and economic difficulties. Drawing inspiration from three influential reports, the EU has put science, technology, and innovation (STI) at the forefront of its plans to drive growth and advance strategic autonomy. This promises significant changes to the continent’s STI sector.

Gerhard Schratt received a grant over 93'900 CHF from the Dr. Wilhelm Hurka Stiftung for projects on Parkinson’s Disease and related Neurodegenerative Disorders. This project will explore the potential of antisense oligonucleotides targeting microRNAs to prevent synapse loss, mitochondrial dysfunction and cell death in a human neuron culture model of Parkinson’s Disease. This represents a first step towards the development of antisense oligonucleotide therapies for Parkinson’s Disease.

Farah Al Toukhi from WIRED discusses work by Andrea Musso and Dirk Helbing about how to decentralize social networks and preserve minority voices.

Blackouts, which are large-scale and long-lasting power outages, can significantly impact society. Planning for their consequences requires continuous attention from the state, its citizens, and the private sector. Due to the catastrophic potential of a blackout and the expected extent of its damage, unpreparedness can be extremely costly.

The term “hybrid threat” is ubiquitous in current security policy debates, as it encapsulates an elusive range of different types of attack. This analysis argues that constructively engaging with a hybrid threat scenario initially requires a clear understanding of the underlying forms of hybrid warfare.
