Sofja Kovalevskaja Award 2012 - Award Winners

Pavel Buividovich

Theoretical Physics

Faster computing, greater insight: enhanced analysis of experiments with particle accelerators
One of the great open questions of particle physics is why there is more matter than antimatter in the universe. Experiments of the type conducted at the Large Hadron Collider at CERN in Geneva are supposed to find the answers. Pavel Buividovich’s research helps to interpret the results of such experiments. He works in Lattice Gauge Theory which makes it possible to solve the fundamental equations of, for example, Quantum Chromodynamics (QCD) – the theory of quarks, gluons and their interactions – using some of the most powerful computers in the world. Buividovich is working on drastically reducing computer time by developing novel algorithms as well as on investigating the impact of very strong magnetic fields, which can be created in heavy-ion collisions - at CERN particle accelerator for example - on the QCD phase transition.

Blood flow in tumours: paths to new therapies
Blood supplies our bodies with a host of important nutrients and plays a central role in fighting infection, but it also facilitates tumour growth and metastasis in cancers. Thus understanding microcirculation, that is, the blood supply via the tiniest blood vessels, like capillaries, is a key to cancer treatment. Blood circulation is not only vital for tumour growth and proliferation but for diagnosis and treatment, too, because the blood vessels also transport imaging agents and drugs. Dmitry Fedosov has developed a computer simulation technique to predict blood flow under diverse conditions. He wants to use this method to investigate blood flow in healthy tissue and in tumours in order to discover, for example, the impact of the more tortuous and leaky blood vessels in tumours on drug delivery. The ultimate aim is to find new strategies for treating cancer.

Tanja Gaich

Organic Chemistry

A building block for all applications: new pathways in active ingredient synthesis
Substances dervied from plants and microorganisms have played an important part in the development of new drugs and pharmaceuticals since time immemorial. But these substances often have to be modified and optimised in order to meet the demands of medical applications. Tanja Gaich has developed an alternative to the complex standard procedures. Based on a single building block, she wants to develop a variety of different compounds and achieve a more efficient synthesis of biologically significant molecules. To do so, she recreates nature’s known, as well as hypothetical, biosynthetic pathways in the lab in order to answer fundamental questions about biosynthesis and broaden the spectrum of modern synthetic chemistry.

Kerstin Kaufmann

Basic Research in Plant Biology

The evolution of flowers
The development of flowers is one of the most important developmental processes in plants. It is regulated by proteins known as transcription factors which control the spatial and time-dependent activity of myriads of other genes. The goal of Kerstin Kaufmann´s research is to unravel how one particular family of such master regulators, the so-called MADS-box factors, functions. For this purpose, she will extend her previous investigations of the model plant Thale Cress to examine other closely-related plant species. The combination of techniques she uses will enable her to compare the regulatory control mechanisms in flower development on the genome-wide level. Her research will provide new insights into the evolution of the master key regulators in flower development and the genes they control.

Na Liu

Optics

Nano-optics for deep cell observation
The still young discipline of nanoplasmonics investigates the tiniest, electromagnetic waves generated by metal particles reacting to light. Na Liu wants to use this technology to observe biological and chemical processes at the level of individual particles. For this purpose she combines gold nanoparticles with cell membranes or DNA and uses modern laser technology and high-resolution microscopes to observe what is actually taking place within a cell or during a chemical reaction. Na Liu wants to use this method to gain new, precise insights in cell biology as well as catalytic chemistry.

Veronika Lukacs-Kornek

Hepatology

Insights into the liver's immune system
The liver has multiple functions, not just in metabolism but also in immune response, which have hardly been investigated so far. Veronika Lukacs-Kornek wants to examine the composition and function of lymphatic tissue cells in the liver and elucidate their role in the development of inflammatory, chronic liver disease which often leads to cancer. Her research is extremely relevant because, apart from transplants, up to now, there are no known effective treatments for many types of chronic liver disease. Each year, more than 100,000 patients in Europe die of liver cirrhosis, the hepatocellular carcinoma of one of the most frequently diagnosed malignant cancers worldwide. Better understanding of the immunological functions as well as of autoimmune diseases of the liver could help to prevent the development and progression of chronic liver disease at an early stage.

Ulf A. Orom

Molecular Biology

How genes regulate protein production
For decades, it has been known that gene expression, the process of transcribing genetic information into proteins, relies on an intermediate step involving Ribonucleic Acids (RNA). Research in recent years has revealed that RNA does not only play an intermediate role in protein synthesis, but also an unexpectedly important role in directly regulating gene expression. Ulf A. Orom investigates long noncoding RNAs that are not directly involved in protein synthesis but, rather, function as enhancers of gene transcription. Achieving greater understanding of the properties and mechanisms of this special Type of RNA is an important aim of the research. This knowledge could be a key to regulating gene expression in vivo and potentially deriving therapeutic applications.

Miriam Ronzoni

Political Theory

Paths to greater justice in times of financial crisis
For a long time, the issue of justice had gone out of fashion, but since the international financial crisis and initiatives like the Occupy Movement it has come to the forefront once again. The same is true of research on theories of justice in political philosophy. In her discipline, Miriam Ronzoni has revitalised a discussion that, at some stage, was criticised for being unpolitical and of little relevance: she now re-connects theories of justice with themes like state regulatory capacity and the reform of international institutions. She campaigns for an original approach that focuses on the interdependence between national and supranational structures on the basis of which legitimate and effective protection and distribution mechanisms, such as the regulation of financial markets and international tax competition, can be developed.

Patricia Schady

Astrophysics

Storms in the universe throw light on the evolution of the first stars
Gamma-ray bursts are the most violent explosions known. For a few seconds they become the most luminous objects in the sky and can be seen out to the edge of the visible Universe. For astronomers they indicate the death of a massive star and the subsequent formation of a black hole. The interaction of the explosions’s blast wave with the surrounding interstellar material creates a multi-wavelength afterglow lasting days and up to weeks after the initial burst. However, in over a third of gamma-ray bursts the optical afterglow is not seen; the so-called “dark” bursts. Patricia Schady’s work has strengthened the view that dark bursts are hidden from sight by obscuring layers of interstellar dust. By statistically determining the properties of the dust in the immediate vicinity of the gamma-ray bursts she can infer the properties of the galaxies in which these explosions occur. Her approach will help to trace the formation of the first stars and galaxies in the early Universe.

Richard Stancliffe

Stellar Physics

Seeking the fingerprint of the Big Bang
The origin of the elements has occupied mankind since time immemorial. The Big Bang brought forth hydrogen and helium, but what about the carbon on which life is based, the calcium in our bones and the iron in our blood? The answer lies deep in the interior of stars where thermonuclear reactions create new elements which are then ejected into the Galaxy when a star dies. The oldest surviving stars in our Galaxy are the direct descendants of the short-lived first generation of massive stars. Thus they preserve the chemical fingerprint of this first generation of stars which researchers in Galactic archaeology like Richard Stancliffe are now investigating. He computes detailed models of the evolution of the first stars which enable him to reconstruct the origin of the elements in the stars on today’s firmament.

Athanasios Typas

Microbial Genetics

Sensory organ and doorkeeper: the hidden functions of the bacterial envelope
In recent years, the sequencing of bacterial genomes has advanced in leaps and bounds. Yet, even in model bacteria, we still do not know the function of almost a third of their genes. Nassos Typas is developing large-scale approaches to understand gene function and map new genes to pathways. The focus of his work is the cell envelope with all its complex functions: it protects the bacterium, acting both as a sensor and a permeability barrier. Nassos Typas wants to unravel the network architecture of the envelope, and to shed light on its major processes, including those that impinge on antibiotic resistance and biofilm formation. His findings could help to develop new drugs, but he also aims to improve our understanding and use of the positive role of bacteria for health and the environment.

Samuel Wagner

Microbiology

A jab with an outcome: how bacterial injections work
Bacteria use an array of mechanisms to act on their environment. One such are type III secretion systems, a kind of bionanomachine with which the bacteria inject toxic proteins into their host cells. Using Salmonellae, microbiologist Samuel Wagner investigates how these bacterial injections function on the molecular level and how, for example, the proteins penetrate the inner bacterial membrane in order to be released in the host cell. Since Salmonellae and other bacteria are unable to infect without the action of these nanomachines, Samuel Wagner’s work holds great potential for developing novel antibiotics to inhibit these apparatus. If these mechanisms can be unravelled it might also be possible to convert and use them for the targeted transport of useful proteins within cells.

Nils B. Weidmann

Political Science

The role of Web 2.0: from democratic revolution to ethnic propaganda
As the Arab Spring, at the latest, demonstrated, the Internet is now seen by many as an important tool for democratic change. Groups can communicate, constitute themselves and organise demonstrations. Amateur videos taken with mobile phones and posted online ensure publicity despite state controlled media. However, it has also become easier for anyone to disseminate their own propaganda and agitation. Nils B. Weidmann’s empirical research addresses the role of the Internet and social media in the fight for democratic reform, especially with regard to the interests of ethnic minorities. In the context of a field study in Bosnia he wants to investigate how the Internet influences inter-ethnic attitudes. Employing state-of-the-art methods from information and communication technology he will examine exactly how groups mobilise and constitute themselves for mass demonstrations online and how the size of the protests can be defined.

Yan Yu

Electrochemistry

New technology for the next generation of batteries
They have to be small and light; they have to be safe and store enormous amounts of energy; and they have to be long-lasting, too. More efficient high-capacity batteries are the dream of car manufacturers across the globe because they are the precondition for the advance of electromobility on a grand scale and, it is hoped, will also finally facilitate enhanced power storage in other areas. However, fulfilling all of these requirements has proved as difficult as squaring the circle. Yan Yu’s research on novel storage materials for lithium-based batteries could herald a breakthrough. She works with anodes made of tin nanoparticles embedded in conducting carbon fibres. The advantage of this constellation is that, in contrast to standard tin anodes which degrade over time, these anodes are connected electrochemically but de-coupled mechanically. The outcomes of this research could significantly improve the stability and storage behaviour of the next generation of batteries.
