We use or encounter them every day in various areas. They represent perceptions and ideas: A letter represents a sound, a word or picture stands for an idea, a note for a sound, a chemical formula for a substance, a boundary stone for a territorial claim, a building for an ideology, a gesture for a cue or an assessment. On the one hand, we open up the world to ourselves by using signs; we acquire it, ensconce ourselves in it, and we punctuate it to represent ourselves in it. On the other, this reference to the world and ourselves becomes visible in our sign systems. As manifestations of a certain way of interacting with nature, the environment, and fellow human beings, they provide information about the social order or ethnic distinctions of a certain society or epoch as well as about how it perceives the world and humanity. As a man-made network of meanings, sign systems can be changed and, in doing so, change how we perceive the world and humanity. Linguistically, this may, for example, be done by using an evaluative prefix: human - inhuman, sense - nonsense, matter - anti-matter or by hierarchizing terms, as in upper class and lower class. The consequences of such labeling, therefore, may decide on the raison d'{\^e}tre of the signified within an aspect of reality and the nature of this existence. Since ancient times we have reflected on signs, at first mainly in philosophy. Each era has created theories of signs as a means of approaching its essence. Nowadays semiotics is especially concerned with them. While linguistics focuses on linguistic signs, semiotics deals with all types of signs and the interaction of components and processes involved in their communication. Semiotics has developed models, methods, and concepts. Semiosis and semiosphere, for example, are concepts that illuminate the processing of signs, i.e. the construction of meaning and the interaction of different sign systems. A sign is not limited to a monolithic meaning but is culturally contingent and marked by the socioeconomic conditions of the individual decoding it. Sociopolitical and sociocultural developments therefore affect the processing of signs. Dealing with signs and sign systems, their circulation, and reciprocal play with shapes and interpretive possibilities is therefore an urgent and trailblazing task in light of sociocultural communication processes in our increasingly heterogeneous society to optimize communication and promote intercultural understanding as well as to recognize, use, and bolster social trends. The articles in this magazine illustrate the many ways academia is involved in researching, interpreting, and explaining signs. Social scientists at the University of Potsdam are examining whether statistics about petitions made by GDR citizens can be interpreted retrospectively as a premonitory sign of the peaceful revolution of 1989. Colleagues at the Institute of Romance Studies are analyzing what Alexander von Humboldt's American travel diaries signalize, and young researchers in the Research Training Group on "Wicked Problems, Contested Administrations" are examining challenges that seem to raise question marks for administrations. A project promoting sustainable consumption hopes to prove that academia can contribute to setting an example. An initiative of historians supporting Brandenburg cities in disseminating the history of the Reformation shows that the gap between academia and signs and wonder is not unbridgeable.

Genetische Differenzierung f{\"u}hrte im Laufe von Jahrmillionen zur Ausbildung einer schier unglaublichen Artenvielfalt. Die Evolution hat viele Wege beschritten. Sie hat zu großartiger nat{\"u}rlicher Biodiversit{\"a}t gef{\"u}hrt - zu Organismen, die an sehr unterschiedliche Umwelten angepasst sind und zum Teil eine ulkige Gestalt haben oder ein merkw{\"u}rdiges Verhalten zeigen. Aber auch die von Menschenhand gemachte Biodiversit{\"a}t ist {\"u}berw{\"a}ltigend - man denke nur an die 10.000 verschiedenen Rosensorten, die uns entz{\"u}cken, oder die Myriaden unterschiedlicher Weizen-, Gerste- oder Maisvarianten; Pflanzen, die allesamt fr{\"u}her einmal einfache Gr{\"a}ser waren, uns heute aber ern{\"a}hren. Wir Menschen schaffen eine eigene Biodiversit{\"a}t, eine, die die Natur selbst nicht kennt. Und wir „fahren" gut damit. Dank der Genomforschung k{\"o}nnen wir heute die gesamte Erbinformation von Organismen in wenigen Stunden bis Tagen aus- lesen. Sehr viel l{\"a}nger dauert es aber, die zahlreichen Abschnitte eines Genoms funktionell zu kartieren. Die Wissenschaftler bedienen sich dazu vielf{\"a}ltiger Methoden: Dabei geh{\"o}rt es heute weltweit zum Standardrepertoire, Gene gezielt zu inaktivieren oder zu aktivieren, ihren Code zu modifizieren oder Erbinformationen zwischen Organismen auszutauschen. Dennoch sind die Wege, die zur Erkenntnis f{\"u}hren, oft verschlungen. Nicht selten m{\"u}ssen ausgekl{\"u}gelte experimentelle Ans{\"a}tze gew{\"a}hlt werden, um neue Einsichten in biologische Prozesse zu gewinnen. Mit den Methoden der Genomforschung k{\"o}nnen wir nicht nur das erkunden, was sich in der Natur „da draußen" findet. Wir k{\"o}nnen auch fragen: „Wie verh{\"a}lt sich ein Lebewesen, beispielsweise ein Moos, eigentlich, wenn wir es zur International Space Station (ISS) schicken? Und k{\"o}nnen wir daraus Kenntnisse gewinnen {\"u}ber die Anpassungsstrategien von Lebewesen an harsche Umweltbedingungen oder gar f{\"u}r eine sp{\"a}tere Besiedlung des Mondes oder des Mars´?" Oder k{\"o}nnen wir mithilfe der synthetischen Biologie Mikroorganismen pr{\"a}zise, quasi am Reißbrett geplant, so ver{\"a}ndern, dass neue Optionen f{\"u}r die Behandlung von Krankheiten und f{\"u}r die Herstellung innovativer biobasierter Produkte entstehen? Die Antwort auf beide Fragen lautet eindeutig: Ja! (Wenngleich ein Umzug auf andere Planeten derzeit nat{\"u}rlich nicht vornan steht.). Landnutzung durch den Menschen bestimmt die Biodiversit{\"a}t. Andererseits tragen Organismen zur landschaftlichen Formenbildung bei und beeinflussen {\"u}ber kurz oder lang die Zusammensetzung unserer Atmosph{\"a}re. Auch hier gibt es spannende Fragen, mit denen sich die Forschung besch{\"a}ftigt. Um neue Erkenntnisse zu gewinnen, m{\"u}ssen Forscher immer wieder neue Wege einschlagen. Oft kreuzen sich auch Pfade. So war es beispielsweise vor wenigen Jahren noch kaum absehbar, wir stark die {\"o}kologische Forschung beispielsweise von den schnellen DNA-Sequenziermethoden profitieren w{\"u}rde, und die Genomforscher unter uns konnten kaum erahnen, wie die gleichen Techniken uns neue M{\"o}glichkeiten an die Hand geben sollten, die hochkomplexe Regulation in Zellen zu untersuchen und f{\"u}r die Optimierung biotechnologischer Prozesse zu nutzen.

Over millions of years, genetic differentiation has brought about an incredible diversity of species. Evolution has followed many different paths. It has led to an awesome natural biodiversity - to organisms that have adapted to very different environments and are sometimes oddly shaped or behave strangely. Humanmade biodiversity is stunning, too. Just think of the 10,000 rose varieties whose beauty delights, or the myriad wheat, barley, and corn variations; plants that had all once been plain grasses feed us today. We humans create our own biodiversity unknown to nature. And it is serving us well. Thanks to genome research we are now able to read the complete genetic information of organisms within a few hours or days. It takes much longer, however, to functionally map the many genomic sequences. Researchers achieve this through various methods: Activating or deactivating genes systematically, modifying their code, and exchanging genetic information between organisms have become standard procedures worldwide. The path to knowledge is often intricate, though. Elaborate experimental approaches are often necessary to gain insight into biological processes. Methods of genomic research enable us to investigate not only what is "out there" in nature, but also to ask, "How does a living organism, like a moss, react when sent to the International Space Station (ISS)? Can we gain knowledge about the adaptation strategies of living beings in harsh environmental conditions or even for colonizing the Moon or Mars?" Can we use synthetic biology to precisely alter microorganisms, planned on a drawing board so to speak, to create new options for treating diseases or for making innovative biology-based products? The answer to both questions is a resounding Yes! (Although moving to other planets is not on our present agenda.) Human land use determines biodiversity. On the other hand, organisms influence the formation of landscapes and, sooner or later, the composition of our atmosphere. This also leads to exciting scientific questions. Researchers have to strike new paths to reach new conclusions. Paths often cross other paths. A few years ago it was still unforeseeable that ecological research would substantially benefit from fast DNA sequencing methods. Genome researchers could hardly assume that the same techniques would lead to new possibilities for examining the highly complex cellular regulation and optimizing biotechnological processes.
