**Delaying age-related diseases: Can the mushroom-derived nutrient ergothioneine prevent dementia?** Distinguished Professor Barry Halliwell host: Kamil Pabis, PhD, co-organized by VIVA foundation As we sit in this room, we are all breathing oxygen (O2), a gas essential for life for efficient energy production from our food. Yet oxygen has a dark side; some of it makes reactive oxygen species (ROS) such as oxygen radicals, which can damage our body tissues, a factor that contributes to age-related diseases, especially dementia. ROS are not all bad, they help protect against infectious disease via the process of acute inflammation (keeping us alive) yet as we age inflammation isn’t controlled properly and the extra ROS cause more damage that contributes to age-related diseases. ROS levels in the body are controlled by antioxidants, many of which we make ourselves but others come from the diet. Most attention has been paid to vitamins C and E, polyphenols and carotenoids. Consuming diets rich in these compounds correlates with better health, but high doses of them as pure compounds in supplements have had little effect in delaying dementia and other age-related diseases in properly-controlled human clinical trials; supplements cannot replace the effects of a good diet. Interpreting correlational studies as causation is often done, but fraught with danger. In the past ten years we have studied a diet-derived antioxidant that has been almost totally ignored, namely ergothioneine (ET). It is found in many foods, but the major source is mushrooms. Our work has demonstrated that ET is likely very important in maintaining brain health and delaying or preventing dementia and other age-related disease, and pilot clinical trials support this. Evidence is growing that ET is a “longevity vitamin” to support healthy ageing, but rigorous clinical trials are needed to prove this. Its effectiveness may be due to its many additional mechanisms to protect our organs, in addition to acting as an antioxidant. FOOD AND CATERING This event is kindly supported by AVEA. https://avea-life.com/ Please come hungry to enjoy the healthy food!

This is a chance for folks in the AI builder community to participate in our group’s philosophy practice, and for us to broaden our audience within that community. If you have already signed up via Meetup, there is no need to double-register through Luma, should the Luma event be made public.** “You insist that there is something that a machine can't do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that.” —John von Neumann, in a talk at the Institute for Advanced Study at Princeton, 1948 “Everything is computer!” – Donald J. Trump, sometime in 2025 What is computation? These days, it seems more provocative to stipulate what *isn’t* computation. For instance, to suggest that the brain can be functionally anything other than a kind of computer is suspect in the current technological zeitgeist. It seems self-evident that any system of information processing to achieve some output can be explicated in terms of computation. At the foundation of this conviction is the Church-Turing thesis, which both gave a logical definition to and circumscribed the bounds of computation in the form of the Universal Turing Machine, “a most general formulation of machine” (Alan Newell 1980). The idea that the Universal Turing Machine is an abstract design template that can encompass any kind of information-processing system has led some to extend the scope of the thesis to physics itself: “any finite physical system can be simulated by Universal Turing Machines” (David Deutsch 1985). What do we make of such ideas? Instead of fumbling in the accreted fog of the present, a quiet philosophical dialectic was already underway at the time Alan Turing demonstrated Universal Turing Machines in his seminal paper *On Computable Numbers* in 1936. Ludwig Wittgenstein was a contemporary of Turing’s, and made a number of keen observations in the years that followed\*. In particular, Wittgenstein anticipated readings of the Church-Turing thesis such as the above as resulting from an uncritical acceptance of some inferences within Turing’s demonstration. In this session, we will recount the Church-Turing thesis, its various interpretations, the Wittgensteinian response, and what it all means. Join us to discuss and re-examine the notion of computation, in the hopes of coming to a clearer understanding of it. The format of this session will be a presentation followed by an open-ended discussion. *Compiled in Remarks on the Foundations of Mathematics. By L. Wittgenstein

We shall brisk walk from Changi Airport to Stadium MRT Station late afternoon till night time for 2 consecutive days on Saturday and Sunday. For those who like to join us next year April to South Korea - Jeju Island Olle Trail to brisk walk 100 KM in 5 days plus climbing Mount Hallasan 1947m plus City Tour. We need minimum 12 hikers to go, max 16 hikers. In August and November, we can do 3 consecutive days. You may train with us even if you are not going for the trip. Do consider to give yourself a break and build up your stamina, endurance and your hraalth. Interval Walk Training (IWT)—alternating fast-paced walking with slow, recovery-paced walking—is a highly effective, low-impact workout that improves cardiovascular fitness, boosts metabolism, and strengthens muscles. It is superior to steady walking for lowering blood pressure, improving aerobic capacity, reducing visceral fat, and enhancing insulin sensitivity. **Key Health Benefits of Interval Walk Training (IWT):** * **Improved Cardiovascular Health:** IWT strengthens the heart and enhances blood circulation by raising and lowering the heart rate, similar to a high-intensity interval training (HIIT) session. * **Superior Metabolic Control:** It is particularly effective for managing blood sugar and increasing insulin sensitivity, making it ideal for managing or preventing type 2 diabetes. * **Weight Management & Metabolism:** The "afterburn effect" from high-intensity intervals continues to burn calories after the workout ends, aiding in fat loss. * **Increased Aerobic Capacity & Physical Fitness:** Studies indicate that switching paces consistently improves overall stamina and endurance better than continuous walking. * **Muscle & Bone Strengthening:** It strengthens the legs and core, while improving bone density, which is crucial for preventing osteoporosis in older adults. * **Improved Mental Health:** It aids in stress reduction, improves sleep quality, boosts energy, and elevates mood through the release of endorphins. * **Accessible and Sustainable:** The training is low-risk and highly adaptable to various fitness levels, making it popular for improving longevity and mobility in adults over 60. https://www.brownhealth.org/be-well/interval-walking-health-benefits-japanese-walking-method Date: 5 July 2026 (Sun) Registration Time: 4.30 p.m. Start Time: 4.45 p.m. Start point: Changi Airport MRT Station (Green Line) T2 Arrival Hall waiting area near to Swensen restaurant.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.
