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. Whether you're a cell biologist, a hematology enthusiast, or a fellow communicator, this episode offers something for everyone.

In this Mol Bio Minutes episode, Laurynas Alijošius shares a personal story that every molecular biologist can relate to—running PCR, cloning, and sequencing, only to discover frustrating errors in the DNA.

This episode dives deep into PCR accuracy and why it matters for everything from sequencing to cloning and long-read library prep. Laurynas breaks down the major contributors to PCR error, including the fidelity of DNA polymerase, primer design flaws, template impurities, and suboptimal cycling conditions. He then offers a range of solutions—like switching to high-fidelity enzymes, using ready-to-go master mixes, and optimizing magnesium ion concentrations. He also explains how reducing cycle numbers and fine-tuning annealing temperatures can minimize unwanted amplification and ensure more reliable data.

Whether you're troubleshooting or proactively optimizing your workflow, this episode is packed with tips and tools to help you increase PCR accuracy, reduce costs, and save time. Episode notes contain links to enzyme comparisons, primer design tools, and cycling guides to help you PCR with precision.

In this episode of Speaking of Mol Bio, Dr. Cath Moore of the Australian Genome Research Facility (AGRF) discusses how molecular biology technologies are helping to shape Australia’s scientific landscape—from clinical genomics and conservation to bioremediation and agriculture. With over 20 years of experience in both academia and industry, Dr. Moore reflects on the remarkable evolution of genomic tools, from Sanger sequencing to high-resolution spatial multiomics.

She unpacks AGRF’s mission to democratize access to emerging technologies and highlights its role as an early adopter of platforms that help scientists translate academic research into real-world impact. Topics include non-mass spec proteomics, mine site rehabilitation through soil microbiome analysis, and the role of systems biology in modern science.

Dr. Moore also discusses the importance of community education and literacy around genomics, emphasizing how public understanding is key to the safe adoption of emerging technologies like synthetic biology. Finally, she shares career insights and advice for aspiring scientists: stay curious, stay broad, and don’t be afraid to pivot when your work no longer brings joy.
