**Join us for our next Machine Learning in Healthcare meetup in Berlin — proudly sponsored by the QUEST Centre!** Pizza is still back! We are very happy to announce our speaker **Frank te Nijenhuis**, who is a PhD candidate at the ICAI Stroke Lab at Erasmus MC in Rotterdam. With a background in medicine and computer science, he develops deep‑learning models to support real‑time clinical decision-making during stroke treatment. **His talk´s title is:** **Bridging the Implementation Gap in AI for Stroke Interventions: Challenges and Opportunities** **Abstract:** In recent years, rapid advances in artificial intelligence (AI) have led to a proliferation of AI models in medical imaging. However, despite promising performance in research settings, many of these models have yet to translate into meaningful clinical impact. In this talk, Frank will highlight several AI models developed for stroke imaging and examine the barriers that hinder their implementation in clinical practice. He will explore potential pathways to overcome these challenges and conclude with an interactive discussion on co-creation as a strategy to bridge the gap between innovation and real-world adoption. *** 📍 **Location:** “Atrium” conference room, 5th floor, Spreepalais, Anna-Louisa-Karsch-Straße 2, 10178 Berlin 🕕 **Doors open at 6:00 pm** — Talks start **at 7:00 pm!** * 6:00–7:00 pm — Arrival, food, and networking * 7:00 pm — Welcome by the hosts, followed by the talk + Q&A * 8:00 pm — More networking (and possibly more pizza) ⚠️ *Pro tip:* Sometimes only one of the four elevators is working! 📢 **IMPORTANT:** If you RSVP but later realize you can’t make it, *please release your spot* so others can join. *** This meetup is made possible with the kind support of the **QUEST Centre for Responsible Research at BIH**, who are providing both the venue and the delicious refreshments.

Viele Menschen, die Kuba lieben, dort Freundinnen und Freunde haben oder die Kultur aus Tanz, Musik oder Reisen kennen, erleben gerade ein Gefühl von Hilflosigkeit. Gleichzeitig ist oft viel Schweigen zu spüren, obwohl die Situation für viele Menschen auf der Insel sehr schwierig ist. Genau hierfür möchten wir mit dem Resilienz-Café einen Raum anbieten: für Austausch, Einordnung und ehrliches Sprechen darüber, wie man mit dieser Ohnmacht umgehen kann. ​Im Mittelpunkt steht nicht die Politik, sondern der Mensch. Wie halte ich es aus, wenn ich mit Kuba verbunden bin und die Entwicklungen dort mich belasten? Wie kann ich zuhören, ohne wegzuschauen, und präsent bleiben, ohne mich innerlich zu verlieren? Das Café lädt dazu ein, eigene Fragen, Gefühle und Erfahrungen mitzunehmen und gemeinsam darüber ins Gespräch zu kommen. ​Host des Abends ist Till Schrader, Cuban DJ & Ganzheitlicher Coach

This time we will be discussing **Yazmin Zaher: The Coin.** We look forward to seeing you! If you have book suggestions, would like to vote on our next reads, or join us for additional activities, please ask someone at the meeting to add you to our WhatsApp group. Just a heads up: **The cafe only accepts card payments for amounts over €10**, so you may want to bring some cash for smaller orders. Please remember to cancel your participation in good time if you are not coming. This will give someone else enough time to read the book and come to the meeting.

**(Tickets and booking: https://www.lumiberlin.de/postpartum-decoded)** Your body after birth is not broken. It's doing something extraordinarily complex — and nobody explained it to you. Postpartum Decoded is a four-week workshop series that changes that. Every Friday in June, Paola Carrillo Bustamante — computational biologist, biomedical engineer, and mother — brings the real science of postpartum recovery into the room. Not as a list of symptoms to fix, but as a connected system to finally understand. Each session covers a different layer: **Week 1 (5 June) — Your Body as a System** Hormones, tissue repair, brain and nervous system — why recovery is a spiral, not a sprint. **Week 2 (12 June) — Your Brain and Nervous System** The neuroscience behind the fog, the identity shift, and intrusive thoughts — plus tools that actually help. **Week 3 (19 June) — Fuelling and Rebuilding Your Foundation** Why you feel depleted, what your body needs to rebuild, and why Kegels alone aren't the answer. **Week 4 (26 June) — Integration and What Comes Next** Bringing it all together and building your personalised roadmap forward. No platitudes. No bounce-back narratives. Just honest, science-backed information held with warmth and lived experience. **📍 LUMI Yoga & Pilates · Heidestraße 19, 10557 Berlin** **🕙 Fridays 10:00–12:00** **🎟 €25 per session · €85 for the full series** **Tickets and booking:** https://www.lumiberlin.de/postpartum-decoded

Tired of dating apps or surface-level social events? This is different. Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk. This is not speed dating. Not networking. Not “pitch yourself to strangers.” It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it. ## What happens • A 2-hour guided online relational experience • Real-time connection exercises designed to create authentic interaction • A format that adapts in real time to whoever is present • Optional participant-led in-person continuation afterward • WhatsApp connection thread after the session ## This may be for you if: • You’re tired of shallow or repetitive social spaces • You want deeper connection without forced intimacy • You enjoy personal growth, psychology, communication, or relational work • You’re open to meeting people in a more intentional way ## Important This experience runs with whoever is present and takes its own shape each time. Sometimes expansive. Sometimes intimate. Both are the real thing. Booking happens through our website. 👉 Reserve your spot: [https://consciousconnectionsclub.com/join](https://consciousconnectionsclub.com/join) Optional in-person continuation: same day or within 48 hours depending on the city Most people come alone. People often leave surprised by how quickly strangers can feel human, warm, honest, and real. Sometimes awkwardness turns into ease. Sometimes curiosity turns into chemistry. Sometimes people simply remember what it feels like to actually connect again.

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00 - Doors open** **18:30 - Keep Off My LAN: Firefox's Implementation of Local Network Access** In June 2025, researchers exposed Local Mess — a tracking vulnerability where Meta Pixel and Yandex Metrica scripts abused localhost access to silently track millions of Android users across the web. The web platform had a long-standing hole, and Firefox moved quickly to help close it. This talk presents Local Network Access (LNA), the emerging standard that finally tackles these threats along with a backlog of security vulnerabilities tied to localhost and local network devices. It walks through the specification, Firefox's implementation, and the real-world deployment challenges encountered along the way and how they were mitigated. Beyond the "what," this talk opens up a conversation. As LNA is still taking shape in the WICG, it's a chance for people building in the local network and localhost space — and for the adblocker and anti-tracking community, especially those running DNS-based blockers (Pi-hole, AdGuard Home, and similar) — to surface edge cases, breakage, and threat models that should be designed for. Anyone running services on localhost / local network, or operating local DNS-based tracking protection, is invited to share what LNA needs to get right. About the speaker: Sunil Mayya is a software engineer on Mozilla's Firefox Networking team, based in Nuremberg, and a core contributor to Firefox's implementation of the Local Network Access standard. **19:30 - The Devil is in the Defaults - what to do about XSS** This session is about latest defenses against Cross-Site Scritping (XSS), the most prevalent security issue of all times. We will showcase typical XSS bugs and how they can be avoided. We will also explain why previous mechanisms fall short of protecting web sites at scale and why we believe Trusted Types and the Sanitizer API can help closing this gap. The presentation will also give hands-on advice to enable security and development teams adopting these new protections. We will close with a bit on security considerations and remaining risks. About the speaker: Frederik Braun is a security engineer and manager working on Firefox.
