Viewing the infant brain

In recent years, several methods have beendeveloped to visualise which parts of thebrain are most active during specific tasks.Some of these brain imaging processes,especially functional near-infrared opticaltopography and electroencephalography,will be used for a range of studies in thisproject. For example, one approach willexplore how the brains of newborn babiesand infants respond to languages thatdiffer in their rhythmic structure.

refute or refine a variety of hypothesesabout the precise way in which very younghuman infants acquire language skills.With fundamental research it is not possi-ble to promise specific applications at such

an early stage. It is thenature of basic science,however, that it leadson to practical and oftenunpredictable applica-tions in the future.

Problems in learninghow to use language are both common-place, and very debilitating. The more welearn about how this uniquely humanprocess is acquired, the greater are thechances that we will find new ways tounderstand what causes these (develop-ment) problems and how to correct them.

The research also addresses the challengesfacing a multilingual society, such as theEuropean Union. Decisions about teachingseveral languages at different ages canbe made with more confidence whenthe processes underpinning languageacquisition are properly understood.

to make it easier to gain more useful infor-mation from newborn babies and infants.Little functional imaging has been done withvery young infants due to the absence ofsuitable methods. Very high safety standardsmust obviously be metin any such work, andthe experimenters haveto learn how to copewith the low level ofco-operation of theiryoung subjects. Theproject is going toexplore methods to gather data fromhealthy babies in a non-invasive andecologically valid fashion. The partnerswill develop some new techniques andimprove the existing ones for gatheringdata from infants, and will make thistechnology available to other researchersworking in this field.

Theory to build on

The CALACEI project is addressing funda-mental theoretical issues about what itmeans to be human. Its end results in termsof theoretical advancement should confirm,

T he ‘Evolution, development and inten-tional control of imitation’ (EDICI) project

is investigating imitation, a fundamentalaspect of human behaviour, as part of thewide-ranging NEST PATHFINDER initiativeon ‘What it means to be human’.The specific objectives of the project areto answer the following questions: 1) What are the evolutionary origins of thepotential to imitate? 2) What types of experience enhance thepotential for imitation? 3) How does intentional control of imita-tion change in the course of human devel-opment? 4) Do the neuro-cognitive mechanismsthat distinguish self from others play akey role in intentional control of humanimitative performance? and 5) Is intentional control of imitative per-formance uniquely human?EDICI is a highly interdisciplinary project.It combines methods and insights fromthe fields of ethology, evolutionary biol-ogy, neuro-physiology, neuro-psychol-ogy, and comparative, developmental andexperimental psychology. The partnershipincludes leading international experts inthese areas, from academic research groupsin Austria, the United Kingdom, Germanyand Hungary.The project is highly original in terms ofboth its theoretical and methodological

It is also the first to coordinate inves-tigation of non-human animals, children,healthy adults and neurological patients,and the first to make use of techniquesfrom ethology and evolutionary biology,as well as from psychology and neuro-physiology.

Challenging the American model

Europe is the home of evolutionary theory,ethology and genetic epistemology, andwas the site of the earliest scientificresearch on imitation. Despite this his-torical engagement, however, under-standing of imitation in humans is cur-rently dominated by a North Americanmodel, which claims that imitation is aninnate ability. The EDICI project builds onEurope’s historical strengths in the fieldto test a distinctively European model ofimitation, using world-class Europeanfacilities and expertise. The key featuresof this European model are that it incor-porates the significance of evolutionary,developmental and cultural factors intoour understanding of imitation.The latest and most precise behaviouraland imaging techniques are being usedto test samples of non-human animals,

Marmosets, social birds anddomesticated dogs have been selectedas the non-human subjects of the studybecause they are each related to humansin a different way.Alongside many other techniques, func-tional magnetic resonance imaging isbeing used with healthy adults to investi-gate the types of experi-ence that enhance imi-tative potential, andto identify the way inwhich localised activ-ity within the brain isrelated to imitationand activities that donot involve imitation.One key target of thework with humans is tomeasure the strengthof an individual’s poten-tial to imitate, and their capacity to regu-late the expression of this potential inovert imitative performance. These areexamples of aspects of imitation whichcould reveal that imitation is more subtleand complex than just an innate ability.

The FAR project: From associations torules in the development of concepts,

is studying how humans and other specieslearn concepts, as part of the NEST initiativeon ‘What it means to be human’. The projectbrings together five teams of researchersfrom the United Kingdom, France, the Nether-lands and Greece. It is harnessing expertisein animal cognition and evolutionary theory,infant and child development, adult conceptlearning, neuro-imaging, social psychology,neural network modelling, and statisticalmodelling.The partners are looking specifically at thetransition from associative cognition (basedon similarities) to rule-based cognition, inthe context of learning concepts – the pri-mary cognitive means by which we organ-ise things in the world. Any species lackingthis ability would quickly become extinct. Inhumans, however, rule-based cognitionreaches a level of complexity that makesour language, logic and other unique cog-nitive powers possible.

Six objectives

The first objective of the project is to developa computational model of rule-based con-cept learning, both within individuals andthroughout the course of evolution. Neuralnetwork computer simulations are being

T he Neurocom project is part of theNEST-PATHFINDER initiative ‘What it

means to be human’. Its focus is languageand communication, two eminently humanabilities with roots in both early child devel-opment and the evolutionary origins of ourspecies. In Neurocom, experts from a widerange of fields have joined forces: linguists,psychologists, ethologists, neuroscien-tists, and cognitive scientists. Their aim isto distinguish, within human communica-tion channels, major human-specific com-ponents and the neural circuitry thatsupports them in the cortex of the humanbrain.Aware of the progress made in linguisticsand cognitive science, thanks to the inte-gration of developmental data and inter-species comparisons at the behaviourallevel, the project partners predict a furthergreat leap forward once the neural level iswoven into the picture. Today, advancesin neuro-imaging are providing powerfultools for visualising the brain as it per-forms complex functions such as learning,or making sense of someone’s utterancesor actions. The Neurocom partners areeager to exploit these tools and to beginintegrating all that is known about lan-guage and communication, as it relates to

Comparing and integrating

To tackle the developmental and evolution-ary aspects of human language and com-munication, the Neurocom consortiumcompares human adults with babies, andhumans with non-human primates (maca-ques). Teams pursue the following specificobjectives: to map the neural substrates ofthree communication channels (speech,calls, and gestures); to find the neural sub-strate of speaker invariance; to study under-standing of intention in humans and babies,and investigate monkeys’ interpretation ofactions; to study communicative referen-tial cues (gaze shift and pointing), theirsubstrate, and their role in learning newwords; to investigate the neural processingof hierarchical structures in syntax and theneural substrate involved in learning anartificial grammar.The work combines behavioural testing withneuro-imaging. Many experiments involvemapping and monitoring brain regions thatbecome activated and – possibly – showadaptation in subjects placed in a learningcontext (with or without communicative

Our advanced ability to think, to expressemotions and to influence the behav-

Pinpointing molecular change

The Swiss group will search for recentlyevolved genes that have arisen throughretroposition – a type of gene duplica-tion – and that are associated with cogni-tive abilities. A burst of retropositionstarted around the time when the groupcomprising humans, apes and Old Worldmonkeys branched off on the evolutionarytree. Some of the new genes created bythis evolutionary process enabled newneurological functions and resulted,through positive selection, in the devel-opment of higher cognitive abilities.

The German group will use advancedmicro-array technology to scan genesshared by humans and apes to look forthose expressed differently in eachspecies’ brain. As some differences inexpression can lead to changes in genefunction, the project’s challenge is to iden-tify which of these differences are asso-ciated with changes in cognitive abilityand whether they could be responsiblefor the human brain’s uniqueness.

Many of the advances made byhumankind have relied on a sophis-

ticated ability to share knowledge. Theversatility of human communication, andin particular the capacity to communicateverbally and non-verbally about things in theenvironment, is one of the unique featuresof the human species. However, a widevariety of other animals, in groups as evo-lutionarily distant as bees, dolphins anddogs, also exhibit some form of this refer-ential communication at lower levels ofsophistication. Scientists are now propos-ing that human referential communicationis not a single ability but a complex functionresulting from the integration of a variety ofskills and capacities with different evolu-tionary origins.Refcom, part of the PATHFINDER initiativeto investigate ‘What it means to be human’,is a highly ambitious multidisciplinary pro-ject, associating eight European laboratories,which aims to trace these evolutionaryorigins. By comparing referential commu-nication skills in diverse animal species,in the wild and in captivity, with those ofchildren, they hope to contribute to a com-prehensive understanding of the origins ofthis key cognitive ability.

The capacity to communicate

verbally and non-verbally

about things in the environ-

ment is a key element of human

cognitive prowess. To under-

stand which aspects of this

skill are uniquely human, the

Refcom project will compare

the complexity of messages

conveyed by different species

– from a dolphin’s whistle to a

gorilla’s gesture to a child’s

words – in an unprecedented

attempt to trace the different

evolutionary origins of refer-

ential communication across

the animal world.

From gesture to word

The strongest evidence for referential com-munication in non-human primates comesfrom wild monkeys which use various typesof predator-specific alarm calls.

T he question of what makes us humanhas occupied the minds of philosophers

and scientists across the centuries. Recentadvances in genome sequencing have madethe debate even more pertinent, as we nowknow that the quantitative genetic differ-ences between us and many other mam-malian, particularly primate, species, areextremely small. The SEDSU project aims toprovide one answer by demonstrating thatwhat characterises humans is their advancedability to engage in sign use.By studying the relationship between fivedistinct cognitive domains and their rolesin the development of sign use and lan-guage, the project team will show how signuse changes, both with the evolutionarydevelopment of species and within the life-stage development of individuals. The fivedomains – perception and categorisation;iconicity and pictures; spatial conceptual-isation and metaphor; imitation and mimesis;and inter-subjectivity and conventions – areeach characterised by a developmentalprofile linked to a distinct semiotic process,such as the use of pictorial representationsor gesturing. Using an interdisciplinaryapproach and a specially developed set ofanalytical tools, the team hopes to demon-strate that the transition from one devel-opmental stage to another can be explainedby the acquisition of a cognitive ability to

Finding your way home, rememberingwhere you left the car keys or directing

someone to the nearest hospital are exam-ples of highly complex cognitive tasks basedon spatial memory and orientation. Withoutthese functions, navigating through dailylife would be impossible. Our ability toconstruct spatial representations of theoutside world, and to store them in ourmemory is likely to underlie many otherhigher cognitive functions in humans, suchas decision-making and planning.Many other animals possess the ability tonavigate around their environment, butthere are certain higher-order features of thehuman system, such as the ability to com-municate spatial information verbally, whichare uniquely human. The Wayfinding projectwill contribute to the NEST PATHFINDERinitiative to investigate ‘What it means to behuman’, by exploring the particularities of thecognitive organisation of spatial memoryand orientation in humans from an evolu-tionary perspective. This European consor-tium, bringing together six laboratoriesworking in psychology, physiology, biology,neuroscience, anthropology and artificialintelligence, aims to map differences in spa-tial ability, both between humans and otherspecies, and within human populations.

are key functions that help us

to operate in a complex world.

A European research consor-

understanding of how humans

Taking a perspective

How we perceive and remember the loca-tions of objects is multi-faceted and dependson circumstances. In their most advanced,abstract form, our spatial representationshelp us to create mental images of whatother eyes might see from a differentperspective. But it is likely that the humancognitive system has also preserved theevolutionary history of spatial abilitiesand may at times rely on much simplernavigational mechanisms.The Wayfinding project will explore thesedifferent mechanisms and attempt to maptheir evolutionary hierarchy and neural basis,using a combination of experimental cog-nitive tests and neuro-imaging techniquesin rats, monkeys and humans. Once theirplace in the hierarchy is confirmed, theproject will concentrate on those mech-anisms considered uniquely human, such asperspective taking.Intriguing evidence suggests that humanscan shift from one navigational strategyto another according to requirements.Comparing the ways healthy volunteershandle spatial tasks with those sufferingfrom visual or selective neurological impair-ments will provide researchers with a

The kaleidoscope of colours, shapes and sizes that is found in the natural world is clear evidence of the complexity of living organisms.

Complexity is not an easy phenomenon toexplain, however one of its characteristicsis the emergence of new patterns orbehaviours that transcend the individualcharacteristics of component units. TheNEST PATHFINDER initiative on under-standing human complexity, of whichBIOPHOT is part, looks to develop andtransfer solutions and understanding ofreal-world complexity from one area ofscience to another. This builds both cross-national and cross-disciplinary links

that enhance Europeanresearch ability.

The greater under-standing that BIOPHOTwill bring to the hier-archical assemblies ofnatural structural ele-ments over length-scalesof varying orders of

magnitude will provide guidance for thedesign of new synthetic structures. Theimprovement of simulation and modellingtools can significantly reduce the devel-opment costs for man-made nanostruc-tured materials with novel photonic prop-erties. The hope is that a significant‘technology transfer’ from natural biologyto synthetic materials science can beachieved.

The target organisms will also be studiedin terms of their ecological and pheno-logical (the timing of various biologicalphases) history and closely related orcompeting species will be identified forfuture examination.Cross-disciplinary dis-cussions, including theuse of paleontologicaldata where available,will help to determinewhether an organism’soptical scattering mech-anisms give an evolu-tionary advantage thatcan explain the survival of the species in itsecosystem.

Complex interactions

The study of the bio-organism in its envir-onment at different evolutionary epochsrequires analysis of a very large number ofinteractions and dependencies. Similarly,the experimental and theoretical aspectsof the organism’s interaction with light willalso address complexity.

A naesthesia is a subtle and imperfectscience, with the level of anaesthesia

needing to be very carefully controlled toavoid awareness and pain while minimis-ing the risk of complications. The Bracciaproject is exploring ways in which the brain’selectrical activity, especially delta andgamma brain waves, and their interactionswith heart and breathing activity, vary withthe depth of anaesthesia. This work lookinginto the complexities of human physiologyis part of the NEST PATHFINDER initiative on‘Tackling complexity in science’.The project will use measurements onhumans and rats to explore the causal rela-tionships between oscillations in the brain,heart and respiratory system. It asks thefundamental question: ‘Which oscillationsare the drivers of others and which are beingdriven by others?’The first step is to develop a methodologyto test for causal relationships betweeninteracting complex systems. Human sub-jects will be monitored while awake andunder anaesthesia. The results will then beused to develop systems that can modelthe oscillatory behaviour of human, andmore generally mammalian, physiology.

The Braccia project is study-

ing the complex interactions

between electrical activity in

the brain, and oscillations in

during anaesthesia. The find-

ings may reveal new ways to

however, because coupled

and in modern technology.

The need for a better understanding ofanaesthesia is driven by the enormousmedical and societal importance of thistechnique, without which most moderncomplex surgical procedures would beimpossible. The physiology of anaesthesiais not well understood, however, and themechanisms causing loss of consciousnessremain mysterious. Complications due toinadequate control of anaesthesia rangefrom a patient experiencing pain and someunwanted level of awareness, to rareextreme reactions that can lead to braindamage or even death. The most commonproblem is some awareness during surgery,which affects approximately 1 in every900 patients. This is particularly undesir-able in those procedures in which a patientis unable to indicate that they have becomeaware and can feel pain, as can happenwhen a muscle relaxant is used, for exampleduring Caesarean section.Greater understanding of how the body isbehaving during anaesthesia, and howconsciousness and the sensation of paincan be better monitored, would clearly beof enormous benefit in improving generalpractice in the operating theatre.

Levels of anaesthetic need to be carefully calculated for each patient.

Significant possibilities

The most immediate aim of the Bracciaproject is to develop the methods and theunderstanding needed to create a new andimproved kind of anaesthetic monitor. If theresults of the project are as useful as thepartners hope, the next step will be to

prepare the ground for alarge-scale study thatwould refine and testsuch a monitoring sys-tem. The Braccia projectmay be the first steptowards building a sim-ple but highly effectiveanaesthesia control sys-tem that will be found in

every operating theatre, and used to provideprecise management of anaesthesia in away that is completely impossible today.Even if that dream is not fulfilled, however,the project will greatly enhance our knowl-edge about what is going on in the bodyduring surgery, and our understanding of themany interactions within complex systemsin general.

Complex oscillating systems are foundeverywhere, however. They are involvedin many other aspects of physiology, butalso occur in industrial and engineeringsettings, within the operation of computersoftware, and in the many chemical andphysical interactions of the natural envir-onment. Insights gained by studying thecomplexities of anaes-thesia could be relevantto such varied fields assoftware development,aeronautical engineer-ing and environmentalmanagement.The project is a collab-oration between physi-cists, electrical engin-eers, information theorists, medicalscientists and clinicians. This wide multi-disciplinarity reflects the fact that, althoughdirectly focused on anaesthesia, it is explor-ing aspects of complex science that areimportant in a huge range of situations.

The Braccia projectwill greatly enhanceour knowledge aboutwhat is going on in thebody during surgery.

Complexity science is revealing the func-tion and behaviour of complex networks

in the real world, including information-tech-nology networks, power grids and transportnetworks. However, the benefits of thisdeeper understanding are only slowly beingfelt by policy-makers, with those workingwith financial markets slightly ahead.The CAVES project aims to provide a linkbetween complexity science and socialpolicy. Land use is being modelled to deter-mine how it might change, for instance,in response to policy initiatives such asrevision of the EU’s common agriculturalpolicy (CAP). The project forms part of theNEST PATHFINDER initiative on ‘Tacklingcomplexity in science’. In line with this,CAVES is a highly interdisciplinary projectthat: a) helps answer important scientificquestions involving complexity, and b)encourages the transfer of knowledge andtechniques to new areas of application.

autonomous software programs calledagents. The agents in land-use networkstypically represent stakeholders such asfarmers and industrial decision-makers.A complex network changes in response tointernal stress or external shock. A largeexternal shock, for instance, causes anepisode of volatility. In a resilient network,land use will remain largely unchanged asa consequence of this, although dramaticchanges in land use may occur in lessresilient networks.The CAVES project incorporates three casestudies, involving complex networks ofdiffering resilience. The scientific aim isto identify reasons why some complex net-works are more resilient. Models are beingconstructed retrospectively for each casestudy, using datasets of land use overtime to determine the impact of previousepisodes of stress and shock. The modelsare then run forwards in time, so that pastevidence provides the basis for exploringpossible impacts of future shocks.

Complex models can help develop social policy which affects land use.

The CAVES project aims to demonstratehow models of complexity can help to for-mulate social policy. The two Europeancase studies, for instance, are being usedto inform discussions on CAP reform. Themodels obtained from all the case studies

are being analysed forcommon features, toproduce clusters ofgeneralised modelsthat can be applied toall complex networksinvolving land use.Both coarse and fine-grained models arebeing constructed toinvestigate the process

This will be importantwhen constructing global models, such asthose for land use and climate change.The identification of networks susceptibleto change will enable social policy to berefined in order to reduce the impact offuture shocks.

beyond Europe. A dataset from theGrampian region in Scotland shows thatland tenure and social structures havenot changed greatly, despite a series ofexternal shocks that include entry to theEU, changes in agricultural subsidiesand epidemics of livestock disease. Thisresilience arises through the social struc-ture of family farms,flexible land use, andother factors.A case study from theOder River Valley inPoland, on the otherhand, reveals a highrate of change in landuse since the end of theSecond World War. Thisshock arose from polit-ical events and a large-scale shift in popu-lation. Water-management systems wentinto decline and agricultural diversity wasreduced, with crops becoming more vul-nerable to flooding. The prospective part ofthis study will address how farmers in theregion might respond to fresh challengesposed by EU membership. The third casestudy, from the Limpopo Province in SouthAfrica, encompasses the large-scale land-use and demographic changes that occurredafter the fall of the apartheid regime.

P hysicists have a complete understandingof atoms, but that does not mean that

we understand everything that atoms cando. Atoms come together to form molecules,molecules form cells, cells form people, andpeople form a society. Yet we are far fromunderstanding how societies work. Eachstep up the ladder sees a huge increase incomplexity. There have been many attemptsto model complex systems in terms of theircomponent parts but with only partialsuccess.It is commonly believed that such failingsare due to a lack of knowledge about thecomponents and how they interact. If weknew more about chemical reactions orhuman behaviour we might do better. Butaccording to the proposers of the NESTCO3 project, these approaches fail notbecause of insufficient information butbecause the models do not take properaccount of the discrete nature of the com-ponents. Conventional modelling tools usedifferential equations which treat the prop-erties of the system (such as the econ-omy) as smooth and continuous, like afluid, rather than a collection of freelyacting individuals.

Rare events drive change

A key outcome is that random fluctuations,or ‘noise’, can, in some cases, grow tochange the collective behaviour of thewhole system. The proposers argue thatsuch rare events are, in fact, the mainmotor driving changes in collective behav-iour. It is a rather abstract concept, andthe CO3 team intend to put it to practicaluse in a number of socio-economic andbiological applications.For example, a group led by the Universityof Warsaw will create an AB model of themacro-level economic, cultural, and polit-ical mechanisms relevant for social andeconomic change. They will test it on thechanges in Poland since 1989 from a cen-tral to a market economy, where privatebusinesses have become more clusteredthan they were before, with prosperousareas alongside areas of economic decay.The University of Paris 2 will lead anotherstudy looking at how and where businessesstart up and grow. Industry has tradition-ally located in places favourable for naturalresources and transport links.

Shifting alliances of natural scientistshave tried for several decades to forge

a new science by unifying insights froman unlikely assortment of disciplines – ecology, biology, physics, geology, math-ematics, information science and more.If the COLL-PLEXITY partners are on solidground, science in-the-making – the scienceof complexity – has come of age. It is nowmature enough, they believe, to justifythe launch of a project with the potentialfor a great pragmatic pay-off.The project’s name is COLL-PLEXITY. Itsobjective is to fashion practical toolsfor industrial managers as a support toimprove their decision-making for buildingand managing inter-organisational net-works. For an increasing number ofcontemporary businesses, the ability tomanage inter-organisational networks isnothing less than vital.The importance of networking is nothingnew, of course, but it has increased withthe emergence of outsourcing, e-market-places and virtual enterprises. One of theCOLL-PLEXITY partners, the Virtuelle FabrikAG, exemplifies the trend – a network of

Paradigm shift

Being one of the fastest growing scientificdisciplines, complexity science has beenidentified within NEST as a field withsubstantial longer-term promise – a fieldworth strengthening in Europe.

Nevertheless, with others inthe field, the COLL-PLEXITY consortiumacts on the assumption that there arefundamental regularities underlying thecomplexity of the systems that the lattershare with social systems. In respect ofthis, complexity sciencemay hold the key to anew way of tackling theproblems of industrialnetworks.

T he prime function of financial markets isto bear risk, enabling the transfer of

resources from suppliers of liquidity toentrepreneurs and risk-takers. In order to dothat efficiently, they must ensure a properreturn on capital, coupled with market sta-bility so that long-term planning may pro-ceed with confidence and resources canbe allocated efficiently. But the operation ofmarkets is often accompanied by periodsof instability and excessive volatility, includ-ing speculative ‘bubbles’ and crashes.Complex Markets, part of the NESTPATHFINDER initiative on ‘tackling com-plexity in science’, aims to explore an alter-native to the classical theory of rationalbehaviour of a single agent. The alterna-tive proposes a large number of hetero-geneous agents within markets – each ofwhich can employ rational behaviour –but the interaction between these agentsallows collective effects to arise. In thisway, the financial market behaves as acomplex system. Within such a heteroge-neous system, traders can either basetheir investment decisions on the marketfundamentals (dividends, earnings, inter-est rates) or go by patterns and trends inrecent prices. Irregular switching betweenthese two strategies can occur, resultingin irregular price fluctuations.

Research in the area of het-

erogeneous agents and inter-

action in the modelling of

financial markets has made

rapid progress since the 1990s.

Advances in theoretical tools

and computational capacity to

systems have given new insight

into market behaviour. The

Complex Markets project brings

together an interdisciplinary

team to explore these develop-

ments in depth. A more com-

prehensive understanding of

and produce greater stability.

Unravelling the strands

Complex Markets brings together leadingresearchers in numerical simulation, experi-mental economics, mathematical analysis,finance, econometrics and psychology. Itwill build in high-level contact with thefinancial industry and the Bundesbank,the Bank of England and the EuropeanCentral Bank, and specialist advisers inthe US.The team plans to collect and analyse dataon behaviour in specific markets, includingmarkets for wholesale fish, fruit and vege-tables and internet auctions. ComplexMarkets will also study the structure offoreign-exchange markets and stock mar-kets, evaluating the extent and effects ofbehaviourial networks. The prices in mar-kets where traders interact and trade withina small group of other traders, rather thantake the apparently best deals on theirscreens, appear to be much more volatilethan in markets with an electronicallyorganised order book. These studies shouldform the basis for understanding theprocesses that lead to bubbles and crashes.The basic data will also enable the projectteam to derive the general principles ofthe evolutionary approach to the behaviour

W hy did stem-cell research suddenlybecome such an issue in the 2004

US presidential election? What is fuellingthe simmering controversy about genetic-ally modified foods? How are the researchchoices of scientists influenced by whatappears to be fashionable at the time? Inshort, why do scientific research topics likethese suddenly erupt from the labs andsaturate the media? The partners in the CREEN (Critical eventsin evolving networks) project call thesephenomena ‘scientific avalanches’. Just asan avalanche of snow can be forecast bycareful modelling and study of environ-mental conditions, it may one day be pos-sible to predict under what circumstancesscientific avalanches will happen. Andcould we even trigger an avalanche in aconstructive and desirable direction?Such questions can only be answered bya truly interdisciplinary effort from manybranches of the natural and social sci-ences. This project, part of a wider NESTPATHFINDER initiative on complexity inscience, will draw on many strands ofresearch on how information spreads withinsocial networks. Scientists, like journal-ists, are individuals, but the collectivebehaviour of science or the media can beunpredictable, related in a complex wayto the actions of individuals within them.

troversies and fashions in

science can emerge unex-

pectedly, sometimes with

unwelcome political and eco-

nomic effects. What triggers

these so-called ‘scientific ava-

lanches’? An interdisciplinary

team from five countries will

apply insights from physics,

mathematics and the social

sciences to the complex social

networks of science and the

events occur and can their

results will be of interest not

To do this, the team will make use oflarge-scale computer simulations and gridcomputing, and develop new analytical,numerical and simulation techniques. Theinformation gained will be used to identifydesigns of network models showing thebest robustness and flow.

C omplexity and self-organisation arecritical to many biological systems, yet

many questions about how complexityemerges from simpler starting states remainunanswered. Current computer simulationsof complex systems in biology take manyhours to achieve a rather poor copy of whatNature manages perfectly in a split second.The EMBIO project, part of the NEST-PATHFINDER initiative on ‘Tackling com-plexity in science’, aims to provide newtools and approaches to help answer someof these questions. By focusing on oneof the major challenges in modern biology– protein folding – they hope to identify thefundamental principles governing the emer-gence of complexity in self-organisingbiomolecular systems. The interdisciplinary research consortium,comprising eight European laboratorieswith expertise in mathematics, statisticalphysics, chemistry, information theory,biology and computing, will develop highlyinnovative mathematical and computa-tional approaches to characterise thedynamics of self-organisation and applythese to protein structure. Because of its focus on protein folding,EMBIO will have a particular impact inmolecular and structural biology, but its

innovative approach to analysing com-plexity will be relevant to many other sys-tems that give rise to self-organisation.

From chaos to calm

Protein folding is a striking example ofemergent complex behaviour and, beingwell defined, it is an ideal system in whichto study complexity. Most proteins spontan-eously and reproducibly fold from an arbi-trary chain of amino acids to a specific 3Dstructure adapted to their biological function.But although data exists on the chemicalcompositions and structures of thousandsof proteins, it is still not possible to predictaccurately or to explain how and why thistransition to a folded structure takes place,partly because it is a non-linear, dynamicprocess influenced by many factors.As the protein’s final 3D structure is consid-ered the most thermodynamically stableone, scientists currently use a ‘folding fun-nel’ model to explain the dynamics of thetransition. Initially, the chaotic motions ofthe atoms have high levels of free energyand occupy large areas of potential foldingspace. As the protein molecule folds and itsfree energy decreases, the available spaceis reduced to the point where the molecule

understanding of how proteins fold islikely to bring strategic benefits and muchneeded innovation to drug discovery. Mostnew drugs target specific proteins in thebody. In addition, misfolded proteins aredirectly implicated in a number of debili-tating conditions such as Alzheimer’s andCreutzfeldt-Jakob disease.

The consortium alsoexpects its work oncomplexity estimationto impact on areas ofstudy involving compli-cated chaotic dynamics.Examples of these areheart rhythms, where abetter understandingof their chaotic naturecould lead to new diag-

The earthquake and tsunami that ravagedmany communities around the Indian

Ocean in December 2004 were typical ofwhat are called extreme events. They cameas a complete surprise, even though thearea was well known as an earthquake zoneand the underlying geophysical mechan-isms were well understood. Other extremeevents include floods, storms, droughtsand landslides. Not all such events havenatural causes: stock-market crashes,bridge collapses, crime waves and terroristattacks are of human origin but share manyof the same characteristics. A third groupof events – possible catastrophic effects ofclimate change on the economy – have bothnatural and human origins.What they have in common is that they arenot well described by conventional stat-istical methods. Mathematical models ofgeophysical, climatic or socio-economicsystems may have some success in describ-ing their normal state or gradual changesbut are not able to predict sudden, extremeevents. And, what is more, these events doseem to be more common than conven-tional statistical analyses would suggest.

Earthquakes, floods, storms,

riots and stock-market crashes

have one thing in common:

they cannot be successfully

described by conventional

statistical methods. Such

‘extreme events’ are the focus

of E2-C2, a 17-partner NEST

project trying to understand,

and perhaps predict, some of

these unexpected and dam-

aging occurrences. Among

other things, the project will

look at the social and eco-

nomic effects of impending

climate change and even

attempt to forecast crime

waves in major urban centres.

Interconnected hazards

The E2-C2 project, part of a wider NESTPATHFINDER initiative on complexity inscience, will take a new look at both naturaland socio-economic hazards and the con-nections between them. The 17 partnersfrom nine countries will attempt to predictextreme events and also examine theirconsequences.The first task will be to improve the stat-istical theories used to model extremeevents. Conventional statistical methodsare very poor at describing events thathappen infrequently, so a team will devisenew methods of analysis and prediction,and test them against a variety of histor-ical records.The second line of research will look atextreme climatic events in Europe thatarise from the way in which greenhouse-gas emissions and volcanic eruptionsinteract with natural climate variability.Partners will use atmospheric models tosimulate the effects of global warming onthe North Atlantic and Western Europe,and historical and geological records fromthe Campania region of Italy to investigateconnections between volcanic eruptionsand climatic extremes.

hydrological extremes and landslides. Theywill attempt to simulate such events anddevelop methods for forecasting them.The Carpathian Mountains in Romania areknown for their major earthquakes, andanother group will take on the goal of dev-eloping an earthquake prediction system

for the Vrancea region,one of the world’s bestnatural laboratories forstudying earthquakesand landslides.Finally, in perhaps themost ambitious activityin the E2-C2 project, agroup will attempt tocreate a ‘socio-economicbarometer’ to monitorconditions in major urbancentres and provide day-by-day forecasts forimpending crises such

as crime waves, outbreaks of mass vio-lence and surges in terrorist activity.All these extreme events share a commoncharacteristic: the bigger the event the lesslikely it is to happen, but the greater thesocial and economic costs if it does. It is toosoon to say how successful the E2-C2 pro-ject will be, but any progress towards under-standing and anticipating the unexpectedis bound to pay off in the long run.

Can a climatic extreme cause a reversal inthe economic cycle? This is one of severalquestions on the relationship betweenclimate and the economy that will beaddressed by the third research group.Conventional long-term economic modelsare unable to cope with short-lived eventssuch as the winterstorms of 1999 or eventhe summer heat-waveof 2003. Therefore thisgroup will aim at devel-oping novel, fully inte-grated, dynamic modelsof the coupled climate-economy system.

Emergencyplanning

One reason why weneed to understandextreme events is so that we can preparefor them in the design of buildings, controlof land use and emergency planning. Ineach case, we need to know how oftenand how big any events are likely to be.Another task will be to look for evidencethat extreme events are not random, butthat one event may increase the likelihoodof another. The team will look at recordsof strong winds, rogue waves, forest fires,

All these extremeevents share a com-mon characteristic:the bigger the eventthe less likely it isto happen, but thegreater the social andeconomic costs if itdoes.

Methodsfor measuring local (individual nodes) andglobal behaviour are also being assessedusing existing datasets.Data from three domains, representingbiological, socio-economic and innovationnetworks, are being measured. The specificexamples were chosen for ease of datacollection, and their promise as genericmodels. The biological system is a fungalnetwork: one of the simplest living sys-tems to show adaptive behaviour. The mainsocio-economic system is a supply-chainnetwork, involving the flow of information,money and goods from manufacturing,distribution and retail organisations acrossEurope.

S tarling (Sturnus vulgaris) flocks containmany autonomous individuals. How-

ever, the behaviour of the flock cannot simplybe explained by deducing the behaviour ofindividuals. The system is said to be complex,because its behaviour emerges through theinteraction of individuals or agents that arefollowing relatively simple rules.

Bird behaviour

The findings of this project will be ofimmense interest to those working inornithology, animal behaviour and ethol-ogy. Once airborne, consistent patternsquickly appear in a group, or murmation, ofstarlings. Innovative data recording and3-D modelling techniques are being deployedto study the movements of individuals andthe shape of the overall flock. A key technicalchallenge has been to identify individualbirds over time, in images recorded fromthree directions. There have been manyprevious studies on flocking behaviour, butnone with the precise and accurate datacollection or the 3-D modelling capabilitiesof this project.One of the forces driving the evolution ofgrouping in animals is predation. Flockingbehaviour in this study will be recorded

Bird behav-iour changes seasonally, and this is beingcorrelated with an analysis of hormone levelsand social bonding. This will be a steptowards understanding the endocrinecontrol of flocking. The project will providegeneral insights into migration, navigationand animal-group movement.

Modelling collective behaviour

The models start with the idea that individ-ual agents are responsive to the behaviourof others nearest them. Flocks of starlingsexhibit anti-predator responses, for instance,which take the form of ‘terror waves’ that arepropagated through the flock. The behaviourof individuals at the sides and front of theflock are of particular interest in initiatingchanges in collective behaviour.The statistical methods, software tools andvisualisation techniques developed to studystarlings are all easily transferable to otherdomains of study. A range of measure-ments, for instance, to quantify the popu-lation level or density of agents necessaryfor emergent behaviour, can be applied

It is now well established that manyfeatures of the physical, biological, and

sociological world – like molecular struc-tures, neural transmission, crowd behav-iour – are organised in systems or networks.They exist on an infinite range of levels ofsize and complexity, but all are characterisedby the ability of the network to respondcollectively to external conditions or stimuli.Many different theories have been de-veloped in parallel to analyse and modelthese systems. The current stage of scientificunderstanding presents an unrivalled oppor-tunity to develop a more unified networktheory. This is the intention of Uninet, partof the NEST PATHFINDER initiative on ‘Tack-ling complexity in science’.The consortium includes leading researchworkers in five widely differing areas:genetics, metabolism, neurobiology, ecol-ogy and economics. Within each area, theleading group will first review the existingnetwork theories which attempt to describeit. Later, each group will study, model andsimulate up to three topics of particularimpact in that area, which should alsoyield methodologies useful in some of theother subjects.

A world of networks

Understanding complex networks is ascience in its infancy, as computers haveonly recently made it possible to analysethe huge amounts of data needed. Forexample, the explosion of data generatedby genomics still leaves a very long way togo before its implications are unravelled.Similarly, analysis of the behaviour ofindividual animal species, or of functionalgroups like a food web reveals only a frac-tion of the complexity of the whole ecosys-tem and its dynamics. And we all live in avariety of social networks, with differentlevels and scales of interaction from indi-viduals to nations, involving many differentflows, of traffic, of people or of information,for example.Uninet’s five areas for study will be linkedby annual workshops throughout theproject. These will give participants theopportunity to explore aspects of networkmodelling, including data, dynamics androbustness.

T he emerging field of glycomics – thesystem-wide study of the function of

sugars in an organism – is revealing thatsaccharides play multiple roles in a hugenumber of cellular processes. Consequently,pharmaceutical companies are increasinglyinterested in incorporating sugars into mod-ern therapeutics.But today only a handful of approved drugsinclude any functional saccharide groups.The industrial synthesis of even some simplemonosaccharide units is complex, and anoligosaccharide of just five units may involvemore than 50 separate process steps. Inshort, the production costs are frequentlyjust too high.

A natural solution

Living cells, meanwhile, manufacture,metabolise and manipulate sugars with ease,thanks to enzymes. Scientists are thereforekeen to harness this enzymic approach asan alternative to the inefficient and waste-ful synthetic processes used today.The EuroBioSyn project has set itself thechallenge to develop a cell-based systemto produce dihydroxyacetone phosphate(DHAP)-derived monosaccharides for pharma-ceutical applications.

In theproduction phase, the cells are reduced totwo main metabolic pathways which carry outsynthesis and provide energy.

Cutting out the clutter

In nature, cells are not geared to the pro-duction of high yields of a single product.Consequently, two highly efficient moduleswill be generated by optimising the activityof the key pathway enzymes and blocking allother unnecessary metabolism. EuroBioSynbrings together experts – experimental andtheoretical – in molecular biology, func-tional genomics, computational biology,biochemical engineering, and process sys-tems engineering. Together the team willbe able to analyse carbohydrate metabol-ism in E. coli, identify target enzymes foralterations, and optimise the pathwayperformance.

The taste of success

Bioinformatics tools from the field of sys-tems biology, for instance, can identify whichenzymes in side reactions consume inter-mediates and lower yields. The genes formany of these non-productive enzymes canbe knocked out, but some of these enzymesmay be required for the initial growth phase.These need to be elim-inated during a pro-teomic switch from thegrowth phase to theproduction phase.Studies on the fate ofintermediates of thesepathways will providedata on the productiondynamics. System analy-sis will help to producea mathematical modelof the dynamics of thecomplex reaction sequences to identify, thenoptimise, any productivity constraints in theprocess.

The use of antibodies in research is nowroutine, used daily in life-science labora-

tories across the globe. Yet despite theirprevalence, antibody production still relieson a 30-year old technique that is time con-suming and expensive: each time you wanta new monoclonal antibody you have to startfrom scratch. Furthermore, antibodies devel-oped this way are not suitable for humantherapeutics.A group of researchers from Germany,France, Austria and the Czech Republic hasembarked on an ambitious NEST project todevelop a new technology, which could dra-matically reduce the time and effort requiredto produce monoclonal antibodies. The Hyblibconsortium hopes to produce a ‘library’ ofaround one million hybridoma cells, eachexpressing a different antibody. It wouldthen be relatively easy for researchers toscreen the library and pick the cells thatselectively bind their chosen antigen.

Each rearrangementof the genes produces an antibody withdifferent binding specificity, and in total willgenerate a population of cells – the library.The library would contain over one millioncells each expressing a different antibodywith different antigen specificity. It is there-fore likely that within the library an antibodycan be found with at least low to mediumaffinity for almost any target antigen.However, while you are likely to find cellsexpressing an antigen-specific antibody, itis unlikely that the binding affinity is partic-ularly high. A second strand in the project willtherefore develop a method to increase theantibody affinity once a suitable candidatehas been selected from the initial libraryscreen.Changes in antibody-antigen binding affin-ity are caused by mutations in the variableantibody genes. Research has shown thatcertain enzymes are capable of inducing thesemutations in cells in a process called somatichyper-mutation.

In this novel library screening method noanimals are needed. Screening the librarywould be a relatively cheap and simple pro-cedure, especially as each hybridoma celldisplays over 100 000 antibodies on its sur-face, giving a strong signal for antigen bind-ing. Furthermore, as the entire library wouldbe descended from a single cell, background‘noise’ in the screening process would be

markedly reduced, alongwith the number of falsepositives.Although each individualtask in this projectinvolves standard molecu-lar biology procedures,the combined expertisein this project has thepotential to produce anentirely new system formonoclonal antibodyproduction. It has the

potential to dramatically speed up the gen-eration of monoclonal antibodies for appli-cations in basic research, diagnostics andeven human therapeutics.

that once a candidate cell has been selectedfrom the library, the hyper-mutation genescan be turned on. From the resulting mixtureof mutated cells, the rare ones expressinghigher-affinity antibodies can be selected.

Screening made simple

This hybridoma library method has manyadvantages over theconventional hybridomamethod for monoclonalantibody production.First, it is a library ofhuman antibodies. Thisis a major breakthroughas attempts so far togenerate human mono-clonal antibodies (whichare proven to be of thera-peutic use in patients)from hybridoma cellslargely failed. At present ‘human’ monoclon-als can be produced either via a laboriousgenetic engineering process to graft partsof the mouse antibody into the human anti-body scaffold, or by using patented trans-genic mouse strains.

M any new biotechnology businessesrely on the use of live cells as pro-

duction units for proteins of commercialvalue. In such processes, a carrier and deliv-ery system introduces the gene coding forthe protein, with appropriate regulatorysequences, into the host cell. Althoughwidely applied, this method has drawbacks:it has to be optimised for each carrier anddelivery system, over-production of the pro-tein may be harmful to the cell, and purifi-cation may be problematic, particularly ifthe end product is intended for therapeuticuse and subject to strict regulatory require-ments.A solution may lie in the use of cell-freesystems for transcribing genes and trans-lating the transcripts into proteins. Thesesystems tend to have a rather low yield, butif the reactions are carried out under condi-tions of continuous flow (immobilisationof large molecules in a porous material, con-tinuous supply of reagents and removal ofreaction products), it is possible to achievea fairly constant rate of protein synthesisover a period of up to 100 hours.The time may be ripe for looking at DNA-based protein synthesis in a new way: howabout creating combinable artificial or semi-biotic modules capable of carrying out their

In a projectcalled Neonuclei, a multidisciplinary consor-tium aims to create self-assembling tran-scription-competent DNA-based modules,to be integrated into semibiotic systems forproducing complex biomolecules.

Neonuclei

The primary goal of the Neonuclei project isto generate synthetic analogues of cellnuclei, capable of self-assembly in mixturesof DNA, macromolecules (or nanoparticles),and lipids. The resulting ‘neonuclei' will con-tain a synthetic ‘genome’, and their internalnano-architecture should be able to sustaingene transcription in the presence of thenecessary enzymes and transcription fac-tors. Beginning with simple model systemsand building up to structures of increasingcomplexity, partners will focus on nano-structures formed in DNA-protein-lipid sys-tems as a result of phase separation. Studieson real nuclei will guide their efforts.The neonucleus ‘genome’ will offer an attract-ive novel feature: controllability of transcrip-tion by non-biological signals. The strategy

The project aims to produce synthetic versions of living cells.

New avenues

If successful, the project should yield novelcell-free expression systems where theneonuclei are used with reagent mixturesof biological origin, lab-on-a-chip type systemswhere the neonucleus is integrated withprotein synthesis modules on a microfluidicdevice, and implant-modified cells where

synthesis of target pro-teins can be switchedon and off as desired.Neonuclei should thuspave the way for thedevelopment of semi-biotic systems as a newarea of R&D.The long-term impact ofthis project could be

considerable. Potential applications ofneonuclei include, among others, safer genetherapy strategies, closed-loop devices forpatient treatment (synthesising complexbiomolecules on demand), and devices orsensors using unstable – but regenerable –biomolecules.

for achieving this is based on the observa-tion that in real nuclei, some genomic regionsare ‘silent’ because the chromatin (i.e. theDNA-containing material) is too compact toallow transcription. Hence, in addition toseveral genes (or repeats of the same gene)and appropriate regulatory sequences, theengineered genome will contain sequencesdesigned to induce (reversible) DNA com-paction in response tophysical or chemicalstimuli.As gene transcription isonly the first step in pro-tein synthesis, proof ofconcept will rely oninterfacing the neonu-clei with systems thatcan translate gene tran-scripts into proteins. These will include con-tinuous-flow transcription-translation kitsand prototype ‘synthesis-on-a-chip’ systems.In addition, the neonuclei will be micro-injected into living cells.

It is amazing to think that the powerful elec-tronics found in computers are actually

based on networks of extremely basic com-ponents: switches that turn on or off depend-ing on input variables. It is also amazing tolearn that scientists are now building simi-lar switches from DNA. By joining togethercarefully selected genes and regulatorysequences, researchers are able to constructartificial ‘circuits’ which are able to senseparticular conditions or signals within a cell,and respond accordingly.An EU-funded project is working to demon-strate the potential of such rationallydesigned gene networks for medical appli-cations. A number of European scientistshave joined together to design network mod-ules that can detect and possibly correctaberrant cellular function in cancer cells.The researchers have decided to focus theirresearch on the p53 signalling system. Thep53 system is able to detect damage to thecell and then tell it either to repair itself ordie. When the system goes wrong, however,cells do not respond properly to damageand cancer may occur. Indeed, the p53 path-way is implicated in almost all tumour types– in around 50% of tumours the p53 proteinhas been altered in some way so that it nolonger functions correctly. The remaining

50% of tumours carry alterations either indirect regulators of p53 or in pathways thateventually lead to p53 activation.The primary objective of the NETSENSORproject is to build a gene network that willdetect several steps in the p53 pathway,identify the step that is not working correctlyand then selectively respond, either by killingthe cell or by repairing a mutant gene, if thisis the case.

Networks of knowledge

The development of this novel systemrequires the expertise of a multidisciplinaryteam. The project includes leading scien-tists from three laboratories and one SMEwith expertise in systems biology, proteindesign, cell biology, cancer therapeutics,viral delivery of genetic constructs, and DNArepair mechanisms. The first task of the group is to constructartificial networks that can sense the stateof the p53 pathway in cells, building onprevious work in this field by various part-ners. Numerous network modules will bedesigned and tested both experimentally(in a variety of p53 aberrant cell lines specif-ically produced within the project) and byusing computer modelling.

Engineers and designers often takeinspiration from nature. Whether it is

self-cleaning paint, Velcro or morphingaeroplane wings, many technologicaladvances are based on designs that haveexisted in the natural world for millions ofyears. Recognising nature’s incredibleengineering and problem-solving skills,scientists often integrate aspects of biologyinto their research projects. Indeed, entirescientific disciplines are emerging thatmerge biology with previously unrelatedfields such as electronics.

Synthetic biology is one of these newdisciplines, using biological research in awide range of technology and engineeringapplications. The idea is to design andproduce simple biological componentsthat can be ‘plugged together’ like elec-tronic parts. These constructed, artificialsystems do not exist in the natural world;they are designed for specific functionsranging from protein engineering tocomputation.

In fact, some synthetic biology is certainlytaking place in Europe, scattered betweena host of different organisations. This frag-mentation means that the overall state ofresearch and its future potential acrossEurope is unclear. The SYNBIOLOGY projectwill therefore conduct the first-ever surveyof this new discipline. It aims to qualify thekey attributes of synthetic biology researchin Europe and North America, and identifydifferences across European countries, theUSA and Canada. From this analysis itshould be possible to highlight variousfactors, such as funding mechanisms, thatcould impact the level and nature of researchin this area and its short- and long-termcommercial possibilities.
