Atoms in Space
*What are atoms doing in space anyways?* This talk will provide a brief overview of applications of quantum technologies in space ranging from precise timing and inertial measurements to fundamental physics.
Quantum technologies have seen a wide field of applications in medicine, geosciences, computing and communications, in many cases bridging the gap from laboratory experiments to commercial products in the last decade. For terrestrial applications that is. But what about going to space?
Quantum physics based sensors and experiments promise higher accuracy, sensitivity or better long term stability as they rely on immutable properties of atoms. When properly manipulated, these (ultra-)cold atoms are likely to outperform state of the art instruments. Experiments conducted on sounding rockets demonstrated important steps like Bose-Einstein Condensate creation during a few minutes in microgravity, enabling more advanced quantum experiments in the future. The International Space Station and the Tiangong Space Station host dedicated experiments like ultrastable clocks as well as flexible research infrastructure for fundamental research benefitting from long free-fall times. However, the deployment of such technologies on satellites is not as advanced. Satellite missions utilizing quantum sensors or performing long term experiments are subject to studies and proposals backed by a broad scientific community aiming at better understanding of climate change, interplanetary navigation or tests of general relativity. First steps towards realization of such missions are taken by ESA, NASA and various national space agencies as well as universities funded by national agencies or the EU.
This talk will detect the current state of atoms in space and give an overview of active programs to deploy quantum sensors on operational satellite missions. The focus is on future applications in geosciences and related fields employing the same technology.

Despite how it's often portrayed in blogs, scientific articles, or corporate test planning, fuzz testing isn't a magic bug printer; just saying "we fuzz our code" says nothing about how _effectively_ it was tested. Yet, how fuzzers and programs interact is deeply mythologised and poorly misunderstood, even by seasoned professionals. This talk analyses a number of recent works and case studies that reveal the relationship between fuzzers, their inputs, and programs to explain _how_ fuzzers work.

Die Legalisierung des Online-Glücksspiels in Deutschland im Jahr 2021 und die zunehmende Normalisierung von Glücksspiel und Sportwetten in den Medien haben ein Umfeld geschaffen, in welchem Glücksspielprodukte leichter zugänglich und gesellschaftlich stärker akzeptiert sind als je zuvor. Diese weit verbreitete Exposition birgt erhebliche Risiken für vulnerable Personen, insbesondere da die Grenzen zwischen Spielen und Glücksspiel zunehmend verwischen. Seit einiger Zeit ist beispielsweise ...

Did you ever wonder where all the drugs, which you can get at a pharmacy, come from? Who makes them, and how? Well, there is no easy answer, because the process of drug discovery and development is a very complex, expensive, and challenging journey, riddled with many risks and failures. This holds true for all types of drugs, from a simple pill to an mRNA vaccine or a gene therapy. Today, scientists support this process with a variety of AI applications, cutting-edge technologies, automation, ...

Zur Überraschung Vieler sind Juristen Wissenschaftler, die nach wissenschaftlichen Maßstäben arbeiten sollten und ihre Schriftsätze und Urteile auch nach stringenten wissenschaftlichen Kriterien gestalten und untereinander diskutieren sollten. Doch nur in einigen Rechtsgebieten funktioniert dies. Wie jede Wissenschaft ist auch die Rechtswissenschaft nur so gut wie das ihr zugrundeliegende Quellenmaterial – in diesem Fall sind das meist Urteile. Empirische Untersuchungen über diese Daten ...

Science advances by extending our senses beyond the limits of human perception, pushing the boundaries of what we can observe. In photon science, imaging detectors serve as the eyes of science, translating invisible processes into measurable and analysable data. Behind every image lies a deep understanding of how detectors see, respond and perform. At facilities like the European XFEL, the world's most powerful X-ray free-electron laser located in the Hamburg metropolitan area, imaging detectors ...

It is 1976 and the USA long stopped going to the Moon when a Soviet automatic landing station called Luna 24 descends to the Lunar surface. It touches down on 3.3 Billion year old rock formations at a place no mission has ever gone before. What exactly happened remains a mystery to this day, but the space probe managed to take a 2.3 m long drill core from the Lunar regolith, packaged the sample in a genius way and launched it for its voyage to Earth. Some days later the sample entered earths ...

**Over the past few decades, nucleic acids have increasingly been investigated as alternative data storage media and platforms for molecular computing. This talk builds on past research and introduces another branch to the field: DNA cryptography based on random chemistry. This technology provides a platform for conceiving new security architectures that bridge the physical with the digital world.**
