To make sure everyone finds each other smoothly, please follow these simple coordination steps: 1️⃣ **RSVP** Thoughtfully If you’re planning to come, tap “Going.” It helps others feel confident joining and builds momentum before the meetup. Even if you’re 80% sure, RSVP. If your plans change, please update your RSVP so others aren’t expecting your attendance. 2️⃣ **Confirm 2 Hours Before** (Essential) To ensure the meetup runs, please comment on this event page at least 2 hours before the start time: “Confirmed for today 😊” This allows everyone to see, ahead of time, who is actually coming. The meetup moves forward when at least 2 people confirm 2 hours before the event. If fewer than 2 confirmations are posted by then, attendance may be low that day. This avoids anyone showing up uncertain. 3️⃣ **Signal Your Arrival** When you arrive, comment on this event page: “Arrived” + where you’re sitting + what you’re wearing Example: “Arrived. Sitting outside near the entrance. Wearing a black t-shirt.” This ensures everyone can easily find each other. Recognition Tip Having a clear profile photo on Meetup is highly encouraged — it makes recognition effortless and helps the group form faster. **When & Where?** 📅 Day: Every Tuesday & Saturday 🕓 Time: **4:00 PM local time** 📍 Meeting point: In front of **Compass Coffee.** **Arrive on time,** smaller groups make it easier to connect. **Why join Just Gutsy?** • Meet open-minded people who genuinely want to connect • Feel at home anywhere in the world • Be part of a growing global solo travel community • Early members get lifetime premium access to the future Just Gutsy app 🚀 Join here 👉 https://justgutsy.com/ WhatsApp: After attending, you’re welcome to join the Washington DC Just Gutsy WhatsApp group to stay connected and suggest spontaneous meetups: 👉 https://chat.whatsapp.com/KwwHR0npG3aB8VykYjN3hw **About Just Gutsy** **Just Gutsy** is a global community for solo travelers who are free spirited, love exploring the world believe that real connections make the best memories. Hi, I am Syrine, I started solo traveling in 2018 and it changed my life, from introvert to extrovert. Along the way, I loved meeting people, but also felt how hard it can be to find connection when traveling alone. I’m building Just Gutsy so no one has to feel alone on the road — and so anyone who’s still shy to take that first step has a welcoming place to start. 💛

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Search for Life Beyond Earth,”** with Måns Holmberg, postdoctoral researcher at the Space Telescope Science Institute and part of a team of astronomers looking for chemical traces of life on distant exoplanets. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-ET](https://events.ticketleap.com/tickets/profsandpints/dc-ET) .] Are we alone in the universe? While many of us have pondered that question, astronomer Måns Holmberg of Baltimore’s Space Telescope Science Institute is seriously focused on answering it. Last year he was part of a Cambridge-led team of astronomers who generated worldwide headlines by announcing that they had discovered potential evidence of a gas produced almost exclusively by life in the James Webb Space Telescope’s data from the atmosphere of a distant world. Dr. Holmberg will talk about how the search for life elsewhere is being conducted and what strides are being made on that front. He’ll describe what it would take to confirm signs of life on such a world, what challenges remain, and how the next wave of observations could ultimately tip the scales. Dr. Holmberg also will look at the role being played by the James Webb Space Telescope (JWST), how it uses infrared light to decode the chemical composition of strange atmospheres, and how it has left us closer than ever to answering the question of whether life exists elsewhere. He’ll discuss astronomers’ growing interest in a new class of exoplanets known as “Hycean worlds”—ocean-covered planets with hydrogen-rich atmospheres that could be surprisingly hospitable to life. We’ll visit K2-18 b, a distant world around twice the size of Earth that orbits in the habitable zone of a cool red-dwarf star 120 light-years away, and discuss why it has become one of the most interesting exoplanets in the search for life. Recent observations from JWST have revealed something extraordinary: the atmosphere of planet K2-18 b contains carbon-based molecules like methane and carbon dioxide and possibly even dimethyl sulfide (DMS), a gas that, on Earth, is almost exclusively produced by life. Dr. Holmberg will discuss what makes DMS a compelling (though not yet definitive) biosignature candidate. You’ll emerge from the talk with a much richer appreciation of the immense possibilities out there among the stars. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: An illustration showing what the exoplanet K2-18 b might look like. Source: NASA, ESA, CSA, Joseph Olmsted (STScI) / Wikimedia Commons

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .] Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go. Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less. Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you. She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level. Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using. You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency. Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior. We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less. You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress.
