The Scientist Speaks

Building miniature brains may sound like a page out of a science fiction novel, but fact is indeed stranger than fiction. Researchers around the world grow brain organoids—3D miniature brains—to better understand brain development, aging, injury, and other disorders, as well as to test new treatment strategies. Some scientists take brain building to the next level by launching their brain organoids into outer space. In this episode, Iris Kulbatski from The Scientist spoke with Alysson Muotri, a University of California, San Diego professor and Stem Cell Program director to learn more about how microgravity affects the cellular and molecular biology of brain organoids and how these discoveries can improve human health.  The Scientist Speaks is a podcast produced by The Scientist’s Creative Services Team.

As a maternal-fetal immunologist at the Washington University School of Medicine, Nardhy Gómez-López investigates the immunobiological pathways that underlie pregnancy complications. Having trained and researched across the globe alongside caring and curious physicians, Gómez-López became hooked on perinatal immunology research. Motivated to help solve the prevalent problem of preterm birth, she currently looks at labor and birth, also called parturition, through a basic research lens. In this Science Philosophy in a Flash podcast episode, The Scientist's Creative Services Team spoke with Gómez-López to learn more about her recent work investigating cellular changes in the maternal-fetal interface during parturition and what motivates her clinically collaborative research perspective.   To learn more about Gómez-López’s research, check out this article.

In this series, we highlight researchers’ unique outlooks on what it means to be a scientist.

In the 1960s, researchers in England noticed an anomaly when investigating chromosomes from surgically removed human tumors. Distinct from the intact chromosomes visible underneath the microscope were numerous “very small double chromatin bodies,” which are today better known as extrachromosomal DNA. Thanks to modern sequencing and imaging techniques, researchers now know that these tiny bits of circular DNA play a big role in cancer outcomes. In this episode, Niki Spahich from The Scientist spoke with Lukas Chavez, an assistant professor in the Cancer Genome and Epigenetics Program at the Sanford Burnham Prebys Medical Discovery Institute, to learn more about his team’s multiomic exploration of extrachromosomal DNA and how it influences medulloblastoma progression and treatment.   Welcome to The Scientist Speaks, a podcast produced by The Scientist’s Creative Services Team.

Paola Arlotta, the Golub Family Professor at Harvard, delves into human brain development using 3D organoids and sequencing techniques, inspired by her high school teacher. The podcast uncovers her captivating research journey and dedication to unraveling the mysteries of the human mind.

Researchers now employ artificial intelligence (AI) models based on deep learning to make functional predictions about big datasets. While the concepts behind these networks are well established, their inner workings are often invisible to the user. The emerging area of explainable AI (xAI) provides model interpretation techniques that empower life science researchers to uncover the underlying basis on which AI models make such predictions.  In this month’s episode, Deanna MacNeil from The Scientist spoke with Jim Collins from Massachusetts Institute of Technology to learn how researchers are using explainable AI and artificial neural networks to gain mechanistic insights for large scale antibiotic discovery.

The field of psychedelics research has exploded in recent years, as scientists dig deeper into the neuroscience and pharmacology of hallucinogens and how their unique properties can be harnessed to understand and treat depression, anxiety, post-traumatic stress disorder, Alzheimer’s disease, dementia, and neurodegenerative diseases. Remarkably, the human body produces its own endogenous psychedelics, the reasons for which have implications for understanding the ordinary and extraordinary states of human consciousness, from creativity and dreaming to near death experiences. In this episode, Iris Kulbatski from The Scientist’s Creative Services Team spoke with Steven Barker, a professor emeritus at Louisiana State University to learn more about the human body’s ability to produce hallucinogenic compounds and their roles in physiological processes.

Every cell within the human body contains the same DNA, but not all cells look and act alike. The key to cellular diversity lies in which genes the cells express or shut down. Cells convey this information to the appropriate machinery through epigenetic modifications. In this episode, Charlene Lancaster from The Scientist spoke with Jonathan Weissman from the Massachusetts Institute of Technology and Luke Gilbert from the University of California, San Francisco to learn about making epigenetic changes in vitro and the application of these tools in research and the clinic.

Cloud-based systems enable remote science experiments, allowing researchers to accomplish experimental breakthroughs from virtually any location with computer access. Remote labs and cloud-connected instruments are revolutionizing the way researchers approach benchwork, improving scientific discovery and education by enabling accessible and automated workflows. In this episode, Deanna MacNeil from The Scientist spoke with Mohammed Mostajo-Radji from the University of California, Santa Cruz; Brandon Sutherland from University of Toronto’s Accelerator Consortium; and Dana Cortade from Align to Innovate, to learn about connecting experiments to the cloud with remote research technologies.
