• No nucleus, no problem – platelet biology and scientific communication

  In this episode of Speaking of Mol Bio, Dr. Beth Webb takes us deep into the world of platelets, often misunderstood components of blood that punch far above their weight in both physiological and pathological processes. As a postdoctoral researcher at the University of Leeds, Dr. Webb explores how endothelial signals influence platelet activity, and how these anucleate cell fragments play roles not only in clotting, but also in immune responses, inflammation, and diseases like cardiovascular disorders and COVID-19.Beth unpacks the technical challenges of isolating and analyzing platelets—particularly in RNA sequencing and qPCR—while stressing the importance of sample purity and the presence of platelet subpopulations. The conversation also touches on the hope of personalized medicine through platelet-based diagnostics and tailored antiplatelet therapies.Beyond the lab, Dr. Webb is an active science communicator, sharing tips on engaging broader audiences through social media, blogs, and video. She emphasizes the importance of resilience, creativity, and starting small when communicating science.

• The hidden language of RNA – how epigenetics is shaping medicine

  This episode teaches that innovation is born at the intersection of curiosity and persistence. Dr. Gudrun Stengel, co-founder and CEO of Alida Biosciences, reveals how her startup is transforming the landscape of RNA research through a novel technology called proximity barcoding. Dr. Stengel’s story exemplifies the power of entrepreneurial spirit in driving scientific discovery, offering a glimpse into how one idea can reshape an entire field.At Alida Biosciences, Dr. Stengel and her team are pioneering new tools for detecting RNA modifications, a largely unexplored realm of epigenetics. Using their proximity barcoding platform, researchers can read multiple RNA modifications simultaneously, uncovering potential biomarkers and therapeutic targets for diseases like cancer, Alzheimer’s, and diabetes. This technology bridges a critical gap in multiomics, allowing scientists to dive deeper into how epigenetic changes influence gene expression and cellular behavior.Beyond the lab, Dr. Stengel shares her experience as a first-time founder, balancing scientific rigor with startup life. From managing a team to fundraising, her journey underscores the importance of resilience, optimism, and maintaining a long-term vision.
