The excitement was not limited to Heidelberg, however, as the audience extended far beyond, with over 600 online attendees joining from over 20 different countries.\u00a0<\/p>\n\n\n\n<p>This year\u2019s lecture took the audience on a fascinating journey into the smallest units of life. EMBL group leader Julia Mahamid opened the window to a cutting-edge technology transforming our understanding of life: cryo-electron tomography, or cryo-ET for short. In contrast to traditional structural biology methods, cryo-ET allows scientists to study the structures of small molecules not only in isolation, but within their native cellular environment &#8211; it can even show their interactions and binding partners.\u00a0<\/p>\n\n\n\n<p>Using <em>Mycoplasma pneumoniae<\/em>, a tiny bacterium that causes respiratory infections, as a model organism, Julia demonstrated how this advanced imaging technique enables ultra-high-resolution views of ribosomes associated with RNA polymerase. This reveals in striking detail, how different antibiotics can disrupt this complex and thus bacterial protein biosynthesis and cellular function. The sense of wonder continued when Julia introduced cryo-focused ion beam milling as a powerful technique for sample preparation which can carve ultra-thin sections out of larger cells or even entire organisms like <em>C. elegans.<\/em> This process enables scientists to look deeper into cells and tissues than ever before, revealing details that were previously invisible even with the best imaging techniques.<\/p>\n\n\n\n<figure class=\"vf-figure wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"600\" class=\"vf-figure__image\" src=\"https:\/\/www.embl.org\/ells\/wp-content\/uploads\/2026\/01\/Insight-Lecture-2025_KTA_HD-3_cropped_1000x600_S.jpg\" alt=\"\" class=\"wp-image-40417\" srcset=\"https:\/\/www.embl.org\/ells\/wp-content\/uploads\/2026\/01\/Insight-Lecture-2025_KTA_HD-3_cropped_1000x600_S.jpg 1000w, https:\/\/www.embl.org\/ells\/wp-content\/uploads\/2026\/01\/Insight-Lecture-2025_KTA_HD-3_cropped_1000x600_S-300x180.jpg 300w, https:\/\/www.embl.org\/ells\/wp-content\/uploads\/2026\/01\/Insight-Lecture-2025_KTA_HD-3_cropped_1000x600_S-768x461.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"vf-text--body vf-text-body--3\">Photo credit: Stuart Ingham Bailey\/EMBL<\/p>\n\n\n\n<p>Julia concluded with an outlook on the future of cryo-ET and the very inspiring reminder that, despite these technological advances, there is still so much to be discovered &#8211; perhaps even by members of the audience themselves.&nbsp;<\/p>\n\n\n\n<blockquote class=\"vf-blockquote vf-u-margin__left--800 | vf-u-margin__bottom--600 vf-u-margin__top--600\">\n  <div>\n    <div>\n      <em>Have no fear!

These ranged&nbsp; from questions on the technology itself (\u201cHow does the ion beam cut the sample?\u201d) over potential future developments (\u201cIs there a way to keep the imaged samples alive?\u201d) all the way to blue sky ideas (\u201cIf you had a magic wand and could choose any structure to look at, which one would you take?\u201d). Each of the questions sparked thoughtful discussions and showed the deep engagement inspired by Julia\u2019s talk. Especially her advice to be fearless when pursuing a career in STEM, because \u201cyou simply can\u2019t fail if you pursue it without fear\u201d left a lasting impression on the audience.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>Many students on-site in Heidelberg also used the snack session after the lecture to engage in deeper conversation with Julia while enjoying pretzels and gingerbread. Altogether, this year\u2019s Insight Lecture once again showcased outstanding scientific innovation and collaboration and, most importantly, may have sparked curiosity and inspired the next generation of scientists.&nbsp;<\/p>\n\n\n\n<a href=\"https:\/\/www.embl.org\/ells\/insight-lecture\/embl-insight-lecture-2025\/#vf-tabs__section-6c32684e-70a9-40e0-8d49-457828447c78\" target=\"_blank\">\n<button class=\"vf-button vf-button--primary\">Watch lecture<\/button>\n<\/a>\n<!--\/vf-button-->\n\n","protected":false},"excerpt":{"rendered":"<p>Looking back on the EMBL Insight Lecture 2025 By Melanie Meihua Brauny A cold winter\u2019s day couldn\u2019t stop over 100 curious students from coming up to EMBL Heidelberg for the 16th Insight Lecture, hosted by the Science Education and Public Engagement (SEPE) office on 16 December 2025.
