[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **"Eugenics Then and Now,”** on a dangerous movement in science and its lessons for current research, with Carlo Quintanilla, molecular biologist and health science policy analyst at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-eugenics](https://events.ticketleap.com/tickets/profsandpints/dc-eugenics) .] Global concerns about the return of eugenic thinking were reignited by Chinese scientist He Jiankui’s 2018 announcement of the first gene-edited babies, Lulu and Nana. He was quickly condemned by the scientific community and jailed for illegal medical practice, but he and others around the world continue experiments with goals echoing eugenic ambitions. As genetic technologies advance at extraordinary speed, society faces a new set of ethical questions about shaping the traits of future generations. Are we entering a new era of eugenics? If so, how should we respond? Hear such questions tackled by Carlo Quintanilla, who studied rare genetic mutations in human disease as a graduate research scientist and instructor at the University of Texas Southwestern Medical Center and now works at the intersection of genomic medicine, science, and society. Dr. Quintanilla will begin by discussing the origins and history of eugenics, tracing its development in the 19th and 20th centuries as an idea, a scientific movement, and a set of policies. He’ll examine the rise of Social Darwinism in the U.K., forced sterilization programs in the United States, and the atrocities committed by the Third Reich in the name of “racial hygiene.” From there, he’ll explore how our ability to shape human health and heredity have been transformed by modern reproductive and genetic technologies such as in vitro fertilization, prenatal and embryo screening, and genome editing. You’ll learn how these tools hold enormous promise when it comes to the prevention and cure of rare and debilitating genetic conditions, yet also raise profound questions related to their potential enablement of a new, technologically driven form of eugenics. Dr. Quintanilla will then delve into the ongoing debate among scientists, bioethicists, and policymakers over what should be classified as eugenics today. He’ll highlight recent controversial uses of genetic and reproductive technologies that are pushing ethical boundaries faster than society can define them, from embryo selection for traits like IQ and height to speculative military interest in genetically enhanced soldiers. These examples raise urgent questions: Where should society draw ethical boundaries? Who gets to decide? And is the term “eugenics” still useful for guiding policy and public debate? We’ll close by examining the social, political, and regulatory forces that will determine the future, considering whether they will restrain the push toward further genetic control or accelerate it. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

**Pre-registration is REQUIRED. RSVP here - [https://hubs.li/Q046VS--0](https://hubs.li/Q046VS--0)** **Speaker:** Michael Novack, Solutions Architect at AIceberg **Topic title:** "Trust What You Can Trace: Making Agentic AI Explainable, Secure, and Enterprise-Ready" As enterprises adopt increasingly powerful AI systems, one critical challenge remains: understanding how and why these systems make decisions. Many modern models - especially large language models - operate as opaque “black boxes,” making transparency, compliance, and trust difficult to achieve. *This webinar introduces the AI Explainability Scorecard, a practical framework for evaluating the transparency of AI systems based on criteria such as faithfulness, consistency, accessibility, and comprehensibility*. Attendees will learn how different model architectures - from K-Nearest Neighbors to neural networks and transformers - vary dramatically in explainability and risk. **The session will also explore real-world techniques for improving visibility into complex models, including surrogate monitoring approaches that map AI behavior to comparable examples.** These methods help organizations build observable, auditable AI systems without sacrificing performance or scalability. By the end of this session, attendees will understand how to move beyond black-box AI toward transparent, accountable, and secure AI deployment - a critical step for enterprises scaling agentic AI in high-stakes environments. You will learn: **\- Why Explainability Is the Foundation of Trustworthy AI** *Learn why transparency isn’t just a technical preference - it’s becoming a legal, ethical, and operational requirement for enterprise AI systems.* **\- The AI Explainability Scorecard Framework** *Understand the five key criteria - faithfulness, comprehensibility, consistency, accessibility, and optimization clarity - for evaluating how explainable an AI model truly is.* **\- How Different AI Models Compare in Transparency** *Discover why some models are inherently interpretable while others require advanced methods to understand their behavior.* **\- Practical Methods for Making Black\-Box AI Observable** *Explore modern techniques - including surrogate monitoring models - that help organizations understand and audit large language models at scale.* 🔗 Stay Connected * **Learn:** Free talks and trainings on the [Ai+ Training platform](https://aiplus.training/). * **Read:** The latest in AI research on the [ODSC Blog](https://opendatascience.com/). * **Chat:** Join the conversation in our [Slack Channel](https://www.google.com/search?q=https://odsc.com/slack). * **Community:** Review our [Code of Conduct](https://odsc.com/code-of-conduct/).

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
