Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of graphene and gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

An open space for real conversation about how technology is shaping our world, and how we can respond with wisdom, purpose, and values. ## COMING UP: ## Life with Augmented Intelligence **Shaping how we live, work, and build in an AI-driven world** From assistants → to collaboration → to autonomous systems *** **A different way of thinking, working, building.** Most people are still using AI at the surface. Answers. Shortcuts. Quick help. But underneath, work is starting to look different: * systems instead of tasks * collaboration instead of commands * design instead of effort This is a space to step into that. Not a workshop. Not a panel. A place to see what’s emerging, hear how others are thinking, and explore what it means for your own life and work. *** ## Tech & Truth Café 📍 Greencourt Innovation Center 🗓️ May 10 & 17 🕐 1:30 – 5:00 PM 1:30 → arrive and connect 2:00 → ideas and conversation 3:00 → demos and exploration 4:30 → wrap up *** **WHO:** If you’ve been experimenting with something interesting, building something, or thinking differently about AI… reach out.

April showers bring May flowers! We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, May 17 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

Come the whole time or if you just spend 30 minutes. All are welcome. You are welcome and encouraged to bring your own coloring supplies but, if you don't have any, I will have plenty and am happy to share! (coloring books, colored pencils, and markers). Part of the mission of this group is to provide us an opportunity to check out AND SUPPORT local businesses. So, please don't bring any outside food/drinks and, while purchasing something isn't at all a REQUIREMENT to participate in the event, I do strongly encourage you to try something from the vendor :) I look forward to seeing and meeting you there! ***\*\*DISCLAIMER*\*\*** Photos may be taken during the event to be shared here on Meetup so feel free to let me know if you'd like to be excluded from them.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“How AI Alters Thinking,”** on dealing with artificial intelligence’s capacity to change and undermine our thought processes, with Eli Alshanetsky, assistant professor of philosophy at Temple University, principal investigator at its Cognitive Integrity Lab, and author of an upcoming book on AI and freedom of thought. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters](https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters) .] Doctors who give bad advice can be sued for malpractice. Teachers belong to a profession with set standards. When artificial intelligence guides you, however, that guidance comes with a disclaimer: Use at your own risk. Every day millions of people take that risk, and usually AI seems genuinely helpful. But even if AI gives us good answers, might its use over time do bad things to how we think? Explore the relationship between AI and our own minds with Eli Alshanetsky, whose Cognitive Integrity Lab studies how artificial intelligence changes how we think, learn, and build trust. Author of *Articulating a Thought* and the upcoming book F*reedom of Thought in the Age of AI*, he’s on the cutting edge of efforts to answer AI-related questions such as: How can we tell when work is truly our own? How can technology support rather than replace authorship and reflection? What does trust mean when AI mediates our relationships with others and with our own thoughts? To set up his discussion of potential consequences of AI, he’ll describe how social media’s impact on society serves as a preview. Social media didn’t just give people what they wanted to click on, it actually changed what they regarded as click-worthy. It broke attention spans and fueled radicalization across millions of very different people. It left us with people who doom-scroll for hours, who can’t focus, who don’t know what to trust anymore. If you’d shown people this version of themselves ten years ago, would they have chosen it? Artificial intelligence is making a similar deal with us, but the stakes are higher. It isn’t chasing clicks. It’s optimized for giving you the most satisfying response to whatever is on your mind right now. The risk over time isn’t just that you’ll get lazy. More profoundly, even when you think hard, your sense of what counts as good thinking—as well as what sounds like you—will shift to match what AI has been feeding you. We’ll consider what kind of person this produces and whether this is someone we want to be or want children to become. Professor Alshanetsky will lay out a practical framework, which he calls “the interaction layer,” for using AI without letting it replace the thinking it’s supposed to support. He’ll also talk about what AI-related concerns should be the focus of parents and educators. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

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!
