Join us for a discussion of ***Cobalt Red: How the Blood of the Congo Powers Our Lives* by Siddharth Kara** Here's the summary: An unflinching investigation reveals the human rights abuses behind the Congo’s cobalt mining operation―and the moral implications that affect us all. Cobalt Red is the searing, first-ever exposé of the immense toll taken on the people and environment of the Democratic Republic of the Congo by cobalt mining, as told through the testimonies of the Congolese people themselves. Activist and researcher Siddharth Kara has traveled deep into cobalt territory to document the testimonies of the people living, working, and dying for cobalt. To uncover the truth about brutal mining practices, Kara investigated militia-controlled mining areas, traced the supply chain of child-mined cobalt from toxic pit to consumer-facing tech giants, and gathered shocking testimonies of people who endure immense suffering and even die mining cobalt. Cobalt is an essential component to every lithium-ion rechargeable battery made today, the batteries that power our smartphones, tablets, laptops, and electric vehicles. Roughly 75 percent of the world’s supply of cobalt is mined in the Congo, often by peasants and children in sub-human conditions. Billions of people in the world cannot conduct their daily lives without participating in a human rights and environmental catastrophe in the Congo. In this stark and crucial book, Kara argues that we must all care about what is happening in the Congo―because we are all implicated. **Let’s meet at Caboose Commons in Fairfax to enjoy some good discussion and meet new friends.**

[Profs and Pints Northern Virginia](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/nv-eugenics-then-and-now](https://events.ticketleap.com/tickets/profsandpints/nv-eugenics-then-and-now) .] 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 United Kingdom, 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.)

Family Constellations is a powerful experiential process that allows you to externally map an issue you’re facing, creating a kind of three-dimensional image of the underlying dynamics. What is often felt only internally becomes visible and tangible, revealing hidden patterns that are not accessible through thinking alone. In this work, we acknowledge what is—without judgment—and begin to restore order where there has been disorder. Unconscious burdens, often carried across generations, can be seen and gently released. As these dynamics shift, the system reorganizes, allowing for a deeper sense of clarity, movement, and belonging. $65 1-5pm Randy Goldberg, LMT is a graduate of the DC Hellinger Institute, and of advanced studies in Family Constellation with Heinz Stark of Germany. He is a former Yoga monk, Craniosacral therapist, and a world-renowned astrologer (both Western and Vedic) interviewed by the Washington Post, NPR, and CNN. He has facilitated Family Constellation therapy for individuals and groups for more than 20 years.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
