@hjluks Because MacOS is a mess now. Bugs like this are small but infinitely annoying. And good luck submitting a bug report. The next version is supposed to be largely by fixes to improve quality.

@MohammedAlo Totally agree with you on 98% of what you say but not in this instance. Check out the Grandmother hypothesis regarding evolution. Living longer begets living longer for the species.

Using focused ultrasound (FUS) in the lab we wanted to mimic what GLP-1 drugs do — without the weekly injections. Using a machine found in every hospital (and every submarine) we stimulated the vagus nerve in obese mice and they lost weight. And they had less inflammation. Does a new future with fewer drugs await?

Tesla FSD Mad Max mode is too aggressive. Almost got pulled over going over 20 mph above the speed limit on FSD. Had to disengage to slow down quickly. This needs to be addressed. $tsla

That chart lacks one gigantic contributor to dyspnea: Age. The drop in v02 max associated the normal physiology of aging is becoming more and more common, especially as we’re living well into our 80s and 90s despite complex medical conditions. Add this to a sedentary lifestyle, and you get profound dyspnea simply with aging.

@gmrfyd969 @SawyerMerritt Would be funny to earn a free Acceleration Boost but then you always use FSD and actually never use the Acceleration Boost.

@SawyerMerritt Can't wait to see what’s in the catalog—free Acceleration Boost as a level-up reward would be insane. ⚡

NEWS: Tesla appears to be building an opt-in loyalty program with gamified rewards. New app code references point to a tiered, gamified system where owners could earn rewards through milestones such as Supercharging, using FSD, or referrals. There will likely be a dedicated in-app catalog, where users may be able to browse and redeem their earned loyalty points for specific products, upgrades, or services. Sounds fun!

🚨NEW STUDY: Extreme endurance exercise inTour de France Cyclist induces widespread metabolic depletion🚴‍♂️ 📉Key nutrients depleted — not elevated • 44% of blood metabolites altered • Amino acids ↓ • Saturated fatty acids ↓ • Carnitine ↓ • Fat oxidation + glutathione pathways strained Exercise is important for health...but these results suggest endurance exercise EXTREMES become a negative metabolic stress (not a surprise).

My OpenClaw personal assistant truly runs my life. I'm at the airport. My agent has the boarding pass, it checks the details through Google Flights. It knows which gate, which check-in areas, and it knows Dubai airport in and out. So I just talk to my agent through voice messages. And it messages me back using text-to-voice. I have headphones on, and it's telling me exactly where to go and when - and give me gentle reminders when I need to get ready. Surreal experience. Living without OpenClaw now would be such a downgrade.

@MichaelMindrum I think the problem is I rode three hours on Zwift yesterday (Four Horseman) and it scrambled my brain. When we were racing bikes we called the post race stupids. :)

Even a better example: Generic 4$ per month spironolactone in HFrEF is so good it does not require a doctored graph.

@drjohnm I agree rosuvastatin is a good drug, but here the baseline rate in control is 2.5% so mathematically ARR would max out at 2.5%. However very few therapies in medicine have been 70 or 80 or 100% effective even against placebo let alone active control like here-1/2

A new Supercharger is coming soon to Valdosta, Georgia. Permits have been filed for an 8-stall station at the Cracker Barrel on St Augustine Rd, located just half a mile off Interstate 75. The site will feature 1 pull-through trailer stall.
