*Video and images shown with full, written informed consent from the patient. Our first ESD of 2024, performed last week, using our saline-immersion technique (SITE)-facilitated, tri-tunnel variation of the pocket-creation method (PCM). The lesion was a 12 x 9cm laterally spreading tumour involving the ileocaecal valve, caecum and ascending colon*. Dissection speed: 28.3 mm^2/min. SITE, which we first described in 2016, enhances patient comfort (avoiding the need for deep sedation), obviates the need for any traction (through buoyancy), enhances optical clarity (through elimination of dissection-related smoke, fat micelles, debris and through intrinsic magnification), and enhances visualisation of vessels and bleeding points. The use of saline (not water) is critical for conductivity. High-effect, forced coagulation enables very effective knife-alone management of vessels and any bleeding, and this, coupled with the use of self-assembling protein matrix gel (Purastat), obviates the need for the use of coagulation forceps. All these factors contribute to increased efficiency, effectiveness and patient comfort. Histopathology of the specimen confirmed complete (R0) resection and showed that the lesion consisted of a low grade dysplastic lesion without any evidence of invasive malignancy, confirming cure. ESD is an endoscopic microsurgical technique which affords an en bloc, organ-preserving, minimally invasive cure for such lesions, which unlike piecemeal resection, offers R0 with virtually no risk of recurrence; this latter point eliminates the need for tight surveillance and related patient inconvenience/risk, also reducing cost and environmental impact. Onwards and upwards for the betterment of minimally invasive care for all our patients!

From preschool_vibes_ on IG: “Explore the engaging world of multisensory learning at our letter I table! At this station, students dive into a variety of hands-on activities designed to reinforce their understanding of the letter I. Starting with a coloring page, they progress to using magnetic bingo chips to trace the letter's shape, which they can magically clear with a magnetic wand. I teach that the letter I, consisting of one big line and two little lines, is a vowel with two sounds—I as in igloo and I as in ice, where vowels can say their own names. For fine motor skills enhancement, students decorate the letter I using seasonal erasers, reinforcing the letter sound with each placement: 'I says I.' They engage in a letter recognition activity by circling all I's in a specially chosen poem during large group readings, enhancing both letter recognition and visual discrimination. This poem is placed in a dry erase pocket for easy cleanup. To further tactile learning, I've prepared tactile letter cards with raised glue dots along each letter, providing a textured guide for tracing. As the holidays approach, our sensory trays get a festive twist: students practice writing I in trays filled with sprinkles and a mix of cinnamon and sugar, learning to use their pointer finger like a pencil. This method not only helps in retaining the shape and sound of the letter I but also keeps the learning fresh and exciting by varying the sensory materials each week. Join us at our letter table and see how we turn learning into a delightful, sensory-rich experience!”

The Nordic Trio: A Tough Match for Russian Corvettes Russian corvettes are among the most heavily armed on the planet, but they would run into trouble against their Nordic counterparts. The Russian corvettes of the Karakurt class are the most heavily armed ones I know of. They carry Kalibr missiles with a range of 2,500 km and hypersonic Zircon missiles. They would be capable of inflicting significant damage on the entire European fleet, which lacks defenses against the Zircon. The Karakurt also features a version of the Pantsir system with a range of 40 km, tested for intercepting ballistic missiles. Yes, the Karakurt demonstrates how the concept of sea dominance can shift with even small vessels capable of projecting power over long distances. However, there is a trio that would serve as a formidable barrier to the Russian corvettes: the Skjold, Hamina, and Visby. The stealth corvettes from Finland, Sweden, and Norway would be a massive headache for the Karakurt, precisely because of their small size and stealth architecture. The Karakurt may possess Kalibr missiles with a 2,500 km range or Zircons capable of reaching nearly 1,000 km, but to locate their targets, the Karakurt relies on drones like the Altius-U, equipped with a multimode sensor suite and multiple capabilities. Facing this trio would not be an easy match for the Altius, precisely because these vessels are designed for operations in contested environments, with an emphasis on low observability. Imagine trying to locate the Skjold, with its advanced stealth design featuring radar-absorbent materials, angular shapes, and a drastically reduced RCS, weighing only 270 tons? On the Altius's radar, it might appear as a small fishing boat under good conditions. And what about the Hamina? Built with aluminum and a composite superstructure (Kevlar and absorbent materials), it reduces radar, thermal, magnetic, and acoustic signatures. With a very low RCS, it would blend into maritime clutter (waves and small objects), operating in silent mode with electronic jamming. And the Visby? This is the stealthiest of all. Made from carbon fiber composites, with angular shapes, retractable/embedded weapons, and reductions in all signatures (RCS up to 99% lower, IR, acoustic, magnetic, hydrodynamic wake), plus advanced jamming and optimized operations to deny aerial sensors. All of them leverage integration with archipelagos for natural camouflage. What could the Altius-U do? Its active radar would need to operate in high-resolution modes, with drastically reduced range (possibly just a few dozen km); EO/IR for optical/thermal identification at extreme close range; SIGINT/ELINT to capture any residual emissions. This would require multiple drones operating in a coordinated manner with much greater exposure, putting the drones at risk from anti-air defenses, plus a bit of luck. By this point, larger vessels might have already been turned into fish habitats by the Zircons and Kalibrs, but this trio would still be standing. The resilience of this trio would force the Karakurt to risk approaching and entering the range of the Nordic corvettes, which are well armed with modern missiles. To make it even harder, all three have ASW capabilities, which would require attention from submarines. The truth is that the Karakurt's target acquisition would only face difficulties in Nordic waters or regions within range of coastal batteries, putting the corvettes themselves at risk. But with greater range and lower visibility, the Russian corvettes would terrorize larger vessels. The Karakurt are capable of providing area denial over thousands of kilometers, demonstrating a new concept in naval area denial. Specifically at this case, The Altius-U would prioritize radar for wide-area scanning, followed by EO/IR and SIGINT for refinement, but the stealth of these corvettes reduces effective ranges and increases failure risks.

A quiet, solidly mounted anvil does make a meaningful difference in the quality of blacksmithing work. When an anvil rattles due to poor bolting, base imperfections, or instability, it absorbs and dissipates much of the hammer’s energy through vibration and movement rather than transferring it efficiently into the hot metal. This leads to less effective deformation with each blow, requiring more strikes before the workpiece cools, which can result in incomplete shaping, uneven grain flow, surface defects, or even cracks from rushed or insufficient hammering. Precision also suffers because vibrations make it harder to land accurate, controlled blows, especially during detailed operations like drawing tapers, punching, or fullering. The smith tires more quickly, leading to greater inconsistency across pieces or production runs, while the excessive bounce accelerates wear on both the anvil face and tools. In contrast, a quiet anvil—firmly bolted to a heavy stand, timber base, or concrete with a flat contact surface—returns nearly all impact energy to the metal. Forging feels crisp and “dead,” allowing cleaner, faster, and more predictable shaping with better metallurgical results, such as improved grain refinement and fewer internal flaws. Modern smiths often add rubber pads or reinforced mounts specifically to achieve this stability, making it one of the highest-return upgrades for consistent, high-quality manufacture.

So getting a lot of questions on how the pre sale will work for the Prediction market DAO. It will be invite only at first, we are raising a low amount of SOL, and giving away a LOW amount of tokens. Once it is filled it's filled. The starting FDV will be LOW float, and LOW FDV. So it's easier for price discovery to happen. There will be a tax auction so snipers wont be able to fuk it. it will be starting at 99%, and then ticking down. If you use our Ui (wen. rich)it will warn you. This stops snipers from messing with snapping up supply, and ill probs add some personal money into the LP to manage it a bit during the dutch-tax-auction. 80% of raised funds will go to the DAO's for trading. and the other 20% will go to the LP. None goes to us. We will not sell tokens. We will make money on the volume, and fees. Tokens earned from us LPing will be burned. I want to do it with a low fdv so people can get in early and participate, but I did a pre sale to reward people who have been testing WenRich ( our trading/launching platform). Once you are invited you can "gamble for allo" as show in the video. To pvp other pre sellers. You can also just deposit for even money. Its optional, but will be experimenting more with this "gamble to get in" feature in the future. See video for more info. there is also going to be a referral link , for invited people to invite others to the pre sale, and there is a small amount of tokens set aside to reward the top refer's. its based off the amount of $$ the people to refer deposit. more $ deposited, better rewards. Easy. I think you guys will like this take on pre-sales. We are going to be experimenting more so feedback is appreciated.

Can CGMs be harmful? Continuous glucose monitors are big business these days, and for sure, they can be helpful. Especially for people with type 1 diabetes and anyone treated with insulin, they can be a godsend. 🙌 However, they are now also promoted as tools for anyone to "avoid blood sugar spikes" to improve health and weight loss. This obviously expands the market massively, but is this a good and helpful way to use them? I would argue a CGM can be a good tool, if you know how to use it right. However, there are a couple of concerning risks if you don't, as I discuss in this clip: 1. Adding fats on top of any food will lower your blood glucose spike, but it can also add tons of extra empty calories, which may be counterproductive for weight loss, etc. In effect, lowering your blood glucose spike this way may lead to weight gain, not weight loss. 2. Healthy people on strict low-carb diets tend to develop "Adaptive Glucose Sparing," a fancy way of saying their glucose levels become very sensitive to even small amounts of carbohydrates. Wearing a CGM in this situation may make people afraid of even tiny amounts of carbs, like a few blueberries, thinking that any carbs are dangerous. A couple days of eating slightly more carbs could remove this issue. Berries and similar foods are hardly dangerous for healthy people. With those two major caveats, I'm all for testing CGMs and learning about blood glucose reactions to food. What is your experience with CGMs? Please share in the comments. More The clip is from my recent appearance on the Optimize Your Body podcast with Martinsilvafitness. Here's the full podcast on YouTube; it's also on Spotify and all other platforms:

First-in-Nation: Integrating ViewFlex X SE ICE with VOLT PFA This week started with a meaningful milestone at St. Bernards Healthcare (Jonesboro, AR) — first-in-nation combining Abbott’s ViewFlex X Sensor Enabled ICE with the VOLT PFA platform. This builds on our prior experience with: • FIH clinical trial use of ViewFlex X SE • Post-FDA VOLT PFA cases as part of the VOLT LMR What stood out was how well imaging + mapping + energy delivery functioned as one ecosystem in a zero fluoroscopy / zero contrast workflow . Key takeaways 🔹 ICE integrated into EnSite X for real-time anatomic confirmation during PFA 🔹 Safe ICE-in-LA workflow and transseptal planning that reduced unnecessary manipulation in small LA anatomy. Integration helped support transseptal decision-making up front—optimizing trajectory and reducing unnecessary catheter manipulation in small LA anatomy. 🔹 Quick LA shell creation to confirm ridge/posterior wall/carina geometry early 🔹 Small atria lesion strategy: integration helped us decide tighter antral lesions vs intentionally addressing a posterior “critical isthmus” when the posterior corridor was inherently narrow 🔹 During VOLT delivery: very low microbubble visualization on ICE and no clinical hemolysis observed VOLT workflow highlights: single-catheter mapping/pacing/ablation, impedance-based contact visualization, balloon-in-basket (8 splines), selective electrode delivery; PVI ± PVI+ as clinically indicated (GA used). Grateful for the St. Bernards EP Lab team and the Abbott clinical support team. #ViewFlexXSE #VOLTPFA #FirstInNation #ICE #EnSiteX #ZeroFluoro #ZeroContrast #EPWorkflow #Innovation #epeeps St. Bernards Healthcare | Arrhythmia Research Group I Abbott I Abbott Cardiovascular

this clip, a plumber breaks down the U.S. Department of Energy’s updated efficiency standards for residential water heaters. These standards, which apply to new models manufactured after May 2029, set higher performance requirements — particularly for larger electric storage tanks. The practical result is that newer electric water heaters will increasingly use heat pump technology, which is significantly more efficient than traditional electric resistance models. Homeowners who choose to upgrade proactively can enjoy meaningful long-term energy savings. According to DOE analysis, switching to a qualifying heat pump water heater can deliver average lifetime savings of around $1,800–$2,000 per unit compared to older standard models, with many households seeing hundreds of dollars reduced from their annual utility bills. These savings can be increased even further by adding two simple, cost-effective upgrades: • A basic timer (or smart controller) so the water heater only runs during off-peak hours or when hot water is actually needed. • Professional-grade Armaflex (or equivalent closed-cell elastomeric foam) insulation wrap on the tank and hot water pipes. This high-quality insulation dramatically reduces standby heat loss — often cutting additional energy waste by 10–25% or more depending on your current setup and climate. Together, the more efficient unit + timer + professional insulation wrap creates a system that uses far less electricity while still delivering reliable hot water. Many homeowners find the combined upgrades pay for themselves through lower monthly bills over time, without any requirement to change anything immediately. This approach gives you control over your energy use and long-term costs on your own timeline. I’m not much on government mandates but I think they’re onto something here this new innovation in water heaters can be a game changer as far as savings if we incorporate a timer and a professional grade insulation job, The DIY’er can really clean up with this one, I put a link to an AO Smith 50 gallon in the first comment, I do highly recommend the expansion tank, it will definitely help with the longevity.
