Summary Although it is clear that human collaborative skills are exceptional, elucidating similarities and differences of proximate processes underlying cooperative interactions between non-primate and primate taxa may have important implications for our understanding of cooperation in humans and non human-animals via a profound knowledge of 1) socio-cognitive skills as adaptations to specific environments and/or 2) the evolutionary background and origin of our own skills. The closely related wolves and dogs constitute the ideal non-primate model to implement this approach, since cooperation is at the core of their social organization and they are adapted to very different environments.
I propose a series of experiments with wolves (N = 20) and identically raised and kept dogs (N= 20) that will focus on cognitive processes closely linked to the emotional system such as empathy, inequity aversion and delayed gratification that are thought to be involved in triggering and maintaining primate cooperation. In Part 1 of the project, we will investigate whether and to what extent these processes are present in canines, while in Part 2 we will elucidate how they influence partner choice in cooperative interactions. Using social network theory, we will integrate knowledge about animals’ emotional tendencies and cognitive abilities to model canine cooperation. This is an important step towards unifying theoretical and empirical approaches in animal behaviour.
CanCoop incorporates innovative methods and a novel approach that has the potential to elucidate the interactions between proximate and ultimate processes in regard to cooperation. The nature of CanCoop guarantees public and media attention needed for proper societal dissemination of the results, which will be relevant for animal behaviour, social sciences, wildlife and zoo management.

Project acronym CC4SOL
Project Towards chemical accuracy in computational materials science
Researcher (PI) Andreas GRÜNEIS
Host Institution (HI) TECHNISCHE UNIVERSITAET WIEN
Call Details Starting Grant (StG), PE3, ERC-2016-STG
Summary This project aims at the development of a novel toolbox of ab-initio methods that approximate the true many-electron wavefunction using systematically improvable perturbation and coupled-cluster theories. The demand and prospects for these methods are excellent given that the highly-accurate coupled-cluster theories can predict atomization- and reaction energies in a wide range of solids and molecules with chemical accuracy (≈43 meV). However, the computational cost involved inhibits their widespread use in the field of materials science so far. A multitude of suggested developments in the present proposal hold the promise to reduce the computational cost beyond what is currently considered possible by the community. These include explicit correlation methods that augment the conventional wavefunction expansion with terms that depend on the electron pair correlation factors. In contrast to the widely-used homogeneous correlation factors, this proposal aims at the investigation of inhomogeneous correlation factors that can also capture van der Waals interactions. Furthermore this proposal seeks to employ a recently developed combination of atom-centered basis functions and plane wave basis sets, maximizing the compactness in the wavefunction expansion. The combination of these ideas bears the potential to reduce the computational cost of coupled-cluster calculations in solids by three orders of magnitude, leading to a breakthrough in the field of highly-accurate ab-initio simulations. As such the study of challenging solid state physics and chemistry problems forms an important part of this proposal. We seek to investigate molecular adsorption and reactions in zeolites and on surfaces, pressure-driven solid-solid phase transitions of two dimensional layered materials and defects in solids. These problems are paradigmatic for van der Waals interactions and strong correlation, and methods that describe their electronic structure accurately are highly sought after.

Researcher (PI) David Anthony Keays
Host Institution (HI) FORSCHUNGSINSTITUT FUR MOLEKULARE PATHOLOGIE GESELLSCHAFT MBH
Call Details Starting Grant (StG), LS5, ERC-2013-StG
Summary Each year millions of animals undertake remarkable migratory journeys, across oceans and through hemispheres, guided by the Earth’s magnetic field. The cellular and molecular basis of this enigmatic sense, known as magnetoreception, remains an unsolved scientific mystery. One hypothesis that attempts to explain the basis of this sensory faculty is known as the magnetite theory of magnetoreception. It argues that magnetic information is transduced into a neuronal impulse by employing the iron oxide magnetite (Fe3O4). Current evidence indicates that pigeons employ a magnetoreceptor that is associated with the ophthalmic branch of the trigeminal nerve and the vestibular system, but the sensory cells remain undiscovered. The goal of this ambitious proposal is to discover the cells and molecules that mediate magnetoreception. This overall objective can be divided into three specific aims: (1) the identification of putative magnetoreceptive cells (PMCs); (2) the cellular characterisation of PMCs; and (3) the discovery and functional ablation of molecules specific to PMCs. In tackling these three aims this proposal adopts a reductionist mindset, employing and developing the latest imaging, subcellular, and molecular technologies.

Host Institution (HI) FORSCHUNGSINSTITUT FUR MOLEKULARE PATHOLOGIE GESELLSCHAFT MBH
Call Details Starting Grant (StG), LS4, ERC-2013-StG
Summary Recent advances in genome sequencing illustrate the complexity, heterogeneity and plasticity of cancer genomes. In leukemia - a group of blood cancers affecting 300,000 new patients every year – we know over 100 driver mutations. This genetic complexity poses a daunting challenge for the development of targeted therapies and highlights the urgent need for evaluating them in combination. One gene class that has recently emerged as highly promising target space are chromatin regulators, which maintain aberrant cell fate programs in leukemia. The dependency on altered chromatin states is thought to provide great therapeutic opportunities, since epigenetic aberrations are reversible and controlled by a machinery that is amenable to drug modulation. However, the precise mechanisms underlying these dependencies and the most effective and safe targets to exploit them therapeutically remain unknown.
Here we propose an innovative approach combining genetically engineered leukemia mouse models and advanced in-vivo RNAi technologies to explore chromatin-associated vulnerabilities at an unprecedented level of depth. Following a first screen in MLL-AF9;Nras-driven AML, which led to the discovery of BRD4 as a promising therapeutic target, we aim to (1) construct a knockdown-validated shRNA library targeting 520 chromatin regulators and use it to comparatively probe chromatin-associated dependencies in diverse leukemia subtypes; (2) explore the mechanistic basis of response and resistance to suppression of BRD4 and new chromatin-associated targets; and (3) pioneer a system for multiplexed combinatorial RNAi screening and use it to identify synergies between established and new chromatin-associated targets. We envision that this ERC-funded project will generate a comprehensive functional-genetic dataset that will greatly complement ongoing genome and epigenome profiling studies and ultimately guide the development of targeted therapies for leukemia and, potentially, other cancers.

Project Chromosome inheritance from mammalian oocytes to embryos
Researcher (PI) Kikue Tachibana-Konwalski
Host Institution (HI) INSTITUT FUER MOLEKULARE BIOTECHNOLOGIE GMBH
Call Details Starting Grant (StG), LS3, ERC-2013-StG
Summary One of the most dramatic transitions in biology is the oocyte-to-zygote transition. This refers to the maturation of the female germ cell or oocyte, which undergoes two rounds of meiotic chromosome segregation and, following fertilization, is converted to a mitotically dividing embryo. We aim to establish an innovative research program that addresses fundamental questions about the molecular processes controlling the mammalian oocyte-to-zygote transition to ensure faithful inheritance of genomes from one generation to the next. We are taking an interdisciplinary approach combining germ cell and chromosome biology with cell cycle and epigenetic studies to understand how maternal factors regulate chromosome segregation in oocytes and chromatin organization in the zygote. A molecular understanding of key players regulating these processes is a requisite step for investigating how their deterioration contributes to maternal age-related aneuploidy and infertility. Aneuploidy is the leading cause of mental retardation and spontaneous miscarriage. The current trend towards advanced maternal age has increased the frequency of trisomic fetuses by 71% in the past ten years. A better understanding of mammalian meiosis is therefore relevant to human reproductive health.
A special feature of the female germ line is that meiotic DNA replication occurs in the embryo but oocytes remain arrested until the first meiotic division is triggered months (mouse) or decades (human) later. The longevity of oocytes poses a challenge for the cohesin complex that must hold together sister chromatids from DNA synthesis until chromosome segregation. We specifically aim to: 1) elucidate how sister chromatid cohesion is maintained in mammalian oocytes, 2) identify mechanisms regulating cohesion in young and aged oocytes, and 3) investigate how the inheritance of genetic and resetting of epigenetic information is coordinated with cell cycle progression at the oocyte-to-zygote transition.

Project Slowing Down Climate Change: Combining Climate Law and Climate Science to Identify the Best Options to Reduce Emissions of Short-Lived Climate Forcers in Developing Countries
Researcher (PI) Kati Marjo Johanna Kulovesi
Host Institution (HI) ITA-SUOMEN YLIOPISTO
Call Details Starting Grant (StG), SH2, ERC-2015-STG
Summary The ClimaSlow project opens new interdisciplinary horizons to identify the best opportunities to enhance the global legal and regulatory framework for reducing emissions of short-lived climate pollutants (SLCFs), with particular attention to developing countries as projected key sources of future SLCF emissions. It proceeds from the assumption that strengthening the global legal and regulatory framework for SLCFs would bring important benefits in terms of slowing down climate change and reducing local air pollution. However, legal and regulatory options to step up action on SLCFs have not been studied comprehensively. Furthermore, the climate impacts of the various options are not adequately understood.
In contrast to traditional legal analysis that would focus one legal system or instrument, the project will study the relevant legal and regulatory frameworks comprehensively, considering the international, regional, national and transnational levels. It will seek to identify various options, both formal legal instruments and informal regulatory initiatives, to strengthen the global legal and regulatory frameworks applicable to SLCFs. In addition to providing information on best options to regulate SLCFs, this novel, comprehensive approach will help scholars to improve their understanding of the implications of ongoing changes in global legal landscape, including its presumed fragmentation and deformalisation.
Addressing an important gap in current knowledge, the project will combine analysis of the merits of the various legal and regulatory options with estimates of their climate change impacts on the basis of climate modeling. This way, it will be able to identify the alternatives that are the most promising both from the legal point of view and in terms of climate change mitigation potential. The project will generate information that is policy-relevant and context-specific but can simultaneously provide broader lessons and open new interdisciplinary horizons.

Project Crosstalk of Metabolism and Inflammation
Researcher (PI) Andreas Bergthaler
Host Institution (HI) CEMM - FORSCHUNGSZENTRUM FUER MOLEKULARE MEDIZIN GMBH
Call Details Starting Grant (StG), LS6, ERC-2015-STG
Summary Inflammation is a response to noxious stimuli and initiates tissue repair. If resolution fails, however, chronic inflammation develops, which drives tissue damage in many diseases including autoimmunity, cancer and infections. Inflammatory processes are increasingly being appreciated as tightly integrated with metabolic pathways. The molecular crosstalk occurs on different levels including secreted metabolites and cytokines. I hypothesise that this interface of metabolism and inflammation represents a functional rheostat that shapes tissue damage and disease.
Here, I propose to analyse the metabolic and inflammatory processes in a mouse model of chronic viral hepatitis. I chose this model to explore the inflammatory rheostat because the liver is the central organ for metabolism and a hotspot for receiving, processing and distributing local and systemic signals. Cutting-edge technologies including deep sequencing, quantitative proteomics and metabolomics will let us create longitudinal multi-dimensional maps of virus-induced alterations. Paired with immunological, virological and pathological analyses, I expect to identify novel regulatory nodes between metabolism and inflammation. Within our systems-wide experiments and supported by preliminary results, we will specifically focus on the immunomodulatory roles of the metabolite bile acids and oxidative metabolism. These as well as other candidates will be investigated by genetic and pharmacological perturbations in cell culture and in mouse models. Bioinformatics integration of the orthogonal profiling kinetics is expected to reveal novel properties of the molecular networks mediating between metabolism and inflammation.
This proposed cross-disciplinary approach aims to improve our understanding of the crosstalk of metabolism and inflammation. The results of this project may be relevant to viral hepatitis in man and bear broader implications for other inflammatory diseases.

Project Cryptography on Non-Trusted Machines
Researcher (PI) Stefan Dziembowski
Host Institution (HI) UNIWERSYTET WARSZAWSKI
Call Details Starting Grant (StG), PE5, ERC-2007-StG
Summary This project is about the design of cryptographic schemes that are secure even if implemented on not-secure devices. The motivation for this problem comes from an observation that most of the real-life attacks on cryptographic devices do not break their mathematical foundations, but exploit vulnerabilities of their implementations. This concerns both the cryptographic software executed on PCs (that can be attacked by viruses), and the implementations on hardware (that can be subject to the side-channel attacks). Traditionally fixing this problem was left to the practitioners, since it was a common belief that theory cannot be of any help here. However, new exciting results in cryptography suggest that this view was too pessimistic: there exist methods to design cryptographic protocols in such a way that they are secure even if the hardware on which they are executed cannot be fully trusted. The goal of this project is to investigate these methods further, unify them in a solid mathematical theory (many of them were developed independently), and propose new ideas in this area. The project will be mostly theoretical (although some practical experiments may be performed). Our main interest lies within the theory of private circuits, bounded-retrieval model, physically-observable cryptography, and human-assisted cryptography. We view these theories just as the departing points, since the area is very fresh and we expect to soon witness completely new ideas in this field.

Project Comprehensive molecular characterization of secondary organic aerosol formation in the atmosphere
Researcher (PI) Mikael Ehn
Host Institution (HI) HELSINGIN YLIOPISTO
Call Details Starting Grant (StG), PE10, ERC-2014-STG
Summary Key words: Atmospheric secondary organic aerosol, chemical ionization mass spectrometry
The increase in anthropogenic atmospheric aerosol since the industrial revolution has considerably mitigated the global warming caused by concurrent anthropogenic greenhouse gas emissions. However, the uncertainty in the magnitude of the aerosol climate influence is larger than that of any other man-made climate-perturbing component.
Secondary organic aerosol (SOA) is one of the most prominent aerosol types, yet a detailed mechanistic understanding of its formation process is still lacking. We recently presented the ground-breaking discovery of a new important compound group in our publication in Nature: a prompt and abundant source of extremely low-volatility organic compounds (ELVOC), able to explain the majority of the SOA formed from important atmospheric precursors.
Quantifying the atmospheric role of ELVOCs requires further focused studies and I will start a research group with the main task of providing a comprehensive, quantitative and mechanistic understanding of the formation and evolution of SOA. Our recent discovery of an important missing component of SOA highlights the need for comprehensive chemical characterization of both the gas and particle phase composition.
This project will use state-of-the-art chemical ionization mass spectrometry (CIMS), which was critical also in the detection of the ELVOCs. We will extend the applicability of CIMS techniques and conduct innovative experiments in both laboratory and field settings using a novel suite of instrumentation to achieve the goals set out in this project.
We will provide unprecedented insights into the compounds and mechanisms producing SOA, helping to decrease the uncertainties in assessing the magnitude of aerosol effects on climate. Anthropogenic SOA contributes strongly to air quality deterioration as well and therefore our results will find direct applicability also in this extremely important field.

Project The demography of skills and beliefs in Europe with a focus on cohort change
Researcher (PI) Vegard Fykse Skirbekk
Host Institution (HI) INTERNATIONALES INSTITUT FUER ANGEWANDTE SYSTEMANALYSE
Call Details Starting Grant (StG), SH3, ERC-2009-StG
Summary The central research theme of this proposal is the study of social change (skills, productivity, attitudes and beliefs) in Europe along cohort lines and as a function of changing age composition. Using demographic methods, age-specific and cohort-specific changes shall be quantitatively disentangled. The impact of migration flows as well as fertility differentials combined with intergenerational transmissions will be taken into account. It is expected that viewed together, these analyses will result in significant new insights and represent frontier research about likely social and economic challenges associated with ageing and demographic change in Europe and the appropriate policies for coping with them. Unlike projections of long-term economic growth or energy use, demographic forecasts tend to have comparatively low margins of error, even for forecasts half a century ahead. Traits that change systematically along age or cohort lines may therefore be projected with some degree of accuracy, which in turn can allow governments and individuals to better foresee and improve policies for predictable social change. The study will investigate two major topics, the first relating to human capital, skills, and work performance; the second relating to beliefs and attitudes in Europe. Understanding age variation in productivity and how to improve senior workers skills and capacities are paramount for ageing countries. Moreover, individual-level demographic behaviour can have aggregate level implications, including changing societal values and belief structures. The binding element is how such projections will improve one s capacity to foresee and hence develop more targeted policies that relate to ageing societies.
