    Gut Feelings: Understanding Microbiome Influence on Health with Prof. Paul Wilmes

    The gut microbiome has become a hot topic in recent years, capturing the attention of scientists and the general public alike. In our latest podcast episode, we met with Professor Paul Wilmes, head of the Systems Ecology group at the Luxembourg Center for Systems Biomedicine (University of Luxembourg). He shares insights into the complexities of the microbiome, its role in human health, and the groundbreaking research being conducted in Luxembourg. One of the key highlights of the discussion is the impact of the gut microbiome on chronic diseases, particularly Parkinson's disease. Professor Wilmes discusses the ERC Proof of Concept grant he received to explore biomarkers that could detect early signs of Parkinson's disease through shifts in the gut microbiome. This research could pave the way for early interventions and better management of the disease. The conversation also touches on the factors that influence our microbiome, including diet, environment, and even the mode of delivery at birth.  USEFUL LINKS Luxembourg Centre for Systems Biomedicine - https://www.uni.lu/lcsb-en/ More about Prof. Paul Wilmes - https://www.uni.lu/lcsb-en/people/paul-wilmes/ Human Microbiome Project - https://en.wikipedia.org/wiki/Human_Microbiome_Project MetaHIT - https://cordis.europa.eu/project/id/201052/reporting ExpoBiome Project - https://www.uni.lu/lcsb-en/research-projects/expobiome-deciphering-the-impact-of-exposures-from-the-gut-microbiome-derived-molecular-complex-in-human-health-and-disease/

    The Sun Affects Us All - Space Weather with Dr. Carl Shneider

    Did you know Luxembourg is home to space weather experts? Space weather – a term that may sound unfamiliar to many – encompasses a broad range of solar phenomena that can significantly impact life on Earth and the technology we rely on daily. This is the specialisation of Dr. Carl Shneider from SnT (University of Luxembourg), whom we spoke with recently. One of the most fascinating aspects we discussed with Carl is the role of Earth's magnetic field in shielding us from solar radiation. He explained how the sun's magnetic field interacts with our own, creating a protective barrier that helps mitigate the effects of solar storms. However, when these storms are particularly intense, they can penetrate this shield, creating beautiful auroras but also posing potential hazards to our technology and infrastructure. Listeners will also learn about historical events, such as the Carrington Event of 1859, which caused widespread disruptions to telegraph systems and serves as a stark reminder of the potential dangers posed by solar activity. Carl emphasised that as our reliance on technology increases, so does our need for robust space weather monitoring and preparedness.

    From Primes to Privacy: Number Theory and Cryptography with Prof. Jennifer Balakrishnan and Tim Seuré

    What exactly is number theory, and what drives researchers to dedicate their careers to this field? How does this seemingly abstract branch of mathematics connect to the cryptography that secures our digital world? A couple of weeks ago, Luxembourg hosted the 33rd Journées Arithmétiques, providing us with the perfect opportunity to explore these questions. We sat down with two mathematicians: a visiting researcher and a local expert, offering insights from both international and Luxembourg-based perspectives. Our first guest is Prof. Jennifer Balakrishnan from Boston University, who led the team that cracked the notorious "cursed curve" problem. We couldn't resist discussing it and learning more from Jennifer about current big questions. We also explored the mathematical foundations of cryptography with Tim Seuré, a PhD student at the Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg, focusing on fully homomorphic encryption.

    From Rocks to Rescue: The Science of Asteroids and Planetary Defense with Dr. Patrick Michel

    Dr. Patrick Michel, senior researcher at CNRS and global fellow at the University of Tokyo, discusses how our understanding of asteroids has evolved dramatically since the mid-1990s. Early research relied on reflected light observations, but space missions have revealed asteroids as complex geological worlds with diverse shapes and structures. Patrick reflects on this transition from limited knowledge to groundbreaking missions that reveal the intricate features of these celestial bodies.  The episode also covers Asteroid Day, celebrated annually on June 30th, which commemorates the 1908 Tunguska event when an asteroid explosion destroyed a large area of Siberian forest.  Moreover, Patrick recounts the successful DART mission, which tested asteroid deflection techniques and demonstrated humanity's first deliberate alteration of a celestial body's trajectory. He introduces also the Hera mission, designed to investigate the aftermath of the DART impact on asteroid Dimorphos, gathering crucial data on asteroid composition and structure.

    The Lifecycle of Change: Sustainability Strategies with Dr. Thomas Gibon

    Dr. Thomas Gibon from the Luxembourg Institute of Science and Technology breaks down why our assumptions about "green" technology are often wrong. Electric cars, hydrogen fuel, steel production – Thomas shows how Life Cycle Assessment reveals the hidden environmental costs that many don't talk about. The conversation cuts through the usual green-tech hype. That electric car? Its environmental impact depends on how the electricity gets made and where the lithium comes from. Hydrogen as a clean fuel? Not if you're using fossil fuels to produce it. Beyond the technical analysis, Thomas tackles the harder question: how do we build a low-carbon future that people actually want to live in? The discussion moves from engineering assessments to the social and political realities of climate action – because the best technology in the world won't matter if nobody wants to use it.
