*All the presentations are in Hungarian. Thanks for your understanding!* Miért rákkeltő az alkoholfogyasztás? És mi az univerzum két legnagyobb rejtélye? A márciusi Budapest Science Meetupon kiderül. **Az alkohol rákkeltő hatásának nyomában** *Szüts Dávid – HUN-REN TTK, Molekuláris Élettudományi Intézet, Genom Stabilitás Kutatócsoport* Az alkoholfogyasztás ismerten rákkeltő, de vajon miért? Kutatócsoportunk az etanol fő bomlástermékének, az acetaldehidnek a mutagenikus hatását vizsgálta sejttenyészetekben. Az általunk talált hatás enyhe, de egyértelmű: DNS-törésekre utaló genomi átrendeződéseket találtuk sejtvonalakon végzett kísérletekben, és ugyanilyen mutációk alkoholfogyasztással való asszociációját gyomorrák esetekben. Az eredmények alapján az acetaldehid DNS-töréseket előidézve okozhat olyan változásokat a testi sejtek génállományában, amelyek hozzájárulnak a tumorok kialakulásához. **Az univerzum két nagy rejtélye: a sötét energia és a Hubble-feszültség** *Raffai Péter – ELTE TTK Atomfizikai Tanszék* A fizikai kozmológia alapvetése, hogy a világegyetem nagy léptékben homogén. Einstein általános relativitáselmélete szerint egy ilyen univerzum tágul, vagyis a kozmikus távolságok -például a galaxisok között- mindenütt azonos ütemben nőnek. A növekedés mai üteme, a Hubble-állandó, a tágulástörténet kulcsparamétere - az univerzum korát is ő árulja el. A legkülönfélébb megfigyelésekhez a Lambda-CDM kozmológiai modell illeszkedik leginkább; eszerint a tágulás mintegy 5 milliárd éve lassulóból gyorsulóba váltott át, egy ismeretlen összetevő, a sötét energia hatására. A sötét energia mellett a kozmológia legégetőbb kihívásává a "Hubble-feszültség" vált: a Hubble-állandó különböző mérési módszerekkel kétféle értékűnek adódik. Vajon ez csak mérési hiba? Vagy forradalom előjele a kozmológiában? És lehet a két nagy rejtélynek közös feloldása?

*“If children were brought into the world by an act of pure reason alone, would the human race continue to exist?"* Arthur Schopenhauer. Antinatalism asks an uncomfortable question: **Is it morally justified to bring a new person into existence?** In a world marked by suffering, uncertainty, inequality, and social fragility, some philosophers argue that *not being born* may be better than being born at all. This session explores antinatalism, through thinkers like Schopenhauer, and David Benatar. But this is no longer a purely philosophical question. Today, birth rates are collapsing across much of the world. States intervene through incentives, restrictions, and population engineering. Technology separates sex from pregnancy and reproduction from the human body itself. This session explores birth and antinatalism **at the intersection of philosophy, demography, politics, and technology**. **Introduction (15 minutes)** We start with a short introduction of the guests. **Questions to discuss: (1 hour and 45 minutes):** 1. Would you want to be born again? 2. Can it ever be ethical to impose life on someone **without their consent**? 3. Can we meaningfully say someone is “better or worse off” for never existing? 4. How much suffering is it enough to make life not worth starting? 5. Is it worse to risk suffering, or to deny existence entirely? 6. Does society pressure people into reproduction for economic or cultural survival? 7. If antinatalism is right, what follows? Adoption? Voluntary extinction? 8. Can creating a new life be a morally neutral act, or is it better continuing one that already exists? 9. Is having children an act of hope or an act of denial? 10. Can a society that stops reproducing still be a political community — or only an administrative one? is antinatalism politically destabilizing by definition? (Movie: The children of men, Hannah Arendt) 11. Would politics freeze without generational replacement? 12. Would immortality eliminate progress — or stabilize it? 13. Would immortal societies become conservative by default? 14. Is the “right to have a child” absolute—or should it be conditional? If adoption requires screening, why doesn’t biological parenthood? 15. What are the consequences if artificial wombs become viable? 16. What happens when reproduction becomes a technical process rather than a human one? (Recommended documentary: "The Man with 1000 Kids" on Netflix) 17. Was the One-Child Policy an ethical catastrophe — or a brutal but rational response to material limits? If overpopulation causes massive suffering, is coercive birth control ever morally defensible? 18. If parents screen embryos for severe diseases, is that eugenics — or responsibility? 19. Why is state-driven selection immoral, but market-driven selection acceptable? 20. Is the traditional nuclear family the only morally acceptable way to raise a child?

El objetivo de este encuentro es romper el hielo, hablar de las historias que nos gusta escribir, de por qué escribimos, de los libros que nos gusta leer, de qué dificultades encontramos al enfrentarnos al folio en blanco y de qué esperamos del grupo. En definitiva, se trata de conocernos como personas para entendernos como escritores. No importa si has escrito diez novelas, cuatro cuentos o el precioso título de un poema sin versos. Aquí todo aspirante a juntaletras es bienvenido.

Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Kevin Rhodus from Lucy Deep Park Northside is coming to talk to us about his extensive neighborhood Christmas light display that is open in November and December every year north of Dublin. 9 houses over 12 acres and over 120,000 individual controlled lights that sync to music which you can tune into on your radio! Quite impressive! https://ldplights.com/ We'll dive into the tech that runs the show -- should be a blast to hear about this very elaborate display!
