Mayo Clinic researchers have discovered distinct gut microbiome patterns in adults age 50 or younger with colorectal and breast cancers compared with those diagnosed later in life — one of several findings from an analysis of stool samples from 1,364 patients with cancer across cancer types, stages and treatments. Findings also link specific gut bacteria to cancer survival and identify a pretreatment signal associated with chemotherapy toxicity. Learn more: mayocl.in/4yn03Kp

I am loving @instinct– best AI personal assistant so far almost magical. Have invites if folks want to give it a whirl.

MIT published a brutally honest report on what AI is doing to students. A committee of professors and students spent five months studying how AI changed learning on campus, and the findings read like a warning to every university on the planet. Study groups are disappearing. Office hours are emptying out. Problem sets and take-home exams no longer prove anything, because AI can produce credible solutions to almost any written assignment in the undergraduate curriculum. Students who lean on chatbots lose mastery and confidence, and some slip into what the report calls cognitive surrender, reaching for AI at the first hint of struggle. The numbers are rough. 46 percent of surveyed MIT undergrads use LLMs daily. 90 percent worry about their own overreliance. Undergrads who feel AI makes them replaceable now outnumber those who feel it makes them capable. The committee's answer surprised me. They refused to fight AI with surveillance. The report calls AI detectors unreliable, says lockdown browsers feel like spying, and warns that policing students builds a classroom atmosphere of mutual distrust. Instead, MIT wants to rebuild education around the things AI can't replace. That means oral exams, semester portfolios, in-person project work, and a required social component in every subject. The report even floats the idea of rethinking grades entirely, since without a GPA to optimize, much of the incentive to cheat with AI evaporates. The committee warns professors against replacing undergrad research assistants with AI agents just because they're cheaper, because a university exists to grow people, not output. The most famous tech school on earth admitted the machines broke its way of teaching. Its answer is more humans, not more software.

These are probably the most delicious snacks I've ever had. And as far as these things go, not especially bad for you - relatively low sugar and fat. Thanks @united for introducing me to @bobbysuesnuts, am going to be a loyal customer 🙏

Look closer. This is what “change” looks like inside your brain: 1. Stop rehearsing disaster.

My Lp(a) is 175. I cannot change it. My father had heart disease. I cannot change that either. I had a cardiac event at 52 with an LDL of 110. Two stents. A bag of drugs I did not ask for. And a medical system that told me to take the pills and stop asking questions. I stopped the pills. I started asking questions. I spent six years reading the research that most patients never see and most doctors were never taught. My fasting insulin is 2.8. My hs-CRP is under 0.5. My triglycerides are 63. My blood pressure is 112/62. My metabolic age is 43. I am 58 years old. Zero pharmaceutical drugs. I have a CAC of 1600 and I am healthier today than I was at 40. I did not lower my Lp(a). I filled the nitric oxide bank. I silenced every other dragon head. I made sure the machine keeps running. Five scientists across five decades gave us the pieces. Pauling saw the collagen. Diamond saw the glycocalyx. Anderson saw the superoxide. Esselstyn saw the food. The European Heart Journal proved the mechanism. Nobody connected them. Until now. The genes do not have to decide your outcome. The environment does. The wall does. The machine does. The truth heals Upload your blood work. See what they missed. Free. No credit card.

Hey @VodafoneAU - bit hard to pay my bill and avoid those late fees you threaten since your website has been down for 2 days...?

Gaslit by @Cloudflare . Can't get into any of my sites: Google login now not an option, and when I ask for a password reset, I get a code that is about 150+ characters long and stretches to two lines across the end of the page...? And doesn't reset. @cloudflaresupp

Mystery solved - it's because I'm in South Korea. Seems that Google log in is not an option for @Cloudflare - and other companies ?? - so it broke. But via a VPN it worked. FYI @CloudflareHelp

Well that was quite a rude wake up. A 2am wake up in Tokyo - building shaking and an automated voice says Earthquake. Earthquake. We need to 'seek shelter'. So half the hotel goes to the lobby, but now back in our rooms. Now am wired, drinking tea and reviewing my life choices.

This is exactly what folks need to do if they actually want to make their companies legible to AI agents. You have to codify the things that aren’t in email, slack, docs, salesforce, meetings, etc.
After listening to @gregisenberg and @alliekmiller's conversation, I added a Daily Recap to my BrainOS. At the end of the day, I receive an email that prompts me to dictate my thoughts on the day. Once I do that and reply, it's saved as it's own file for my BrainOS to reference in the future. If I reply multiple times in the same day, they're all added to the same file. It's a phenomenal way to fill the gaps that aren't covered by texts, emails, meeting transcripts, DropBox, etc.

The new Atlassian tower in Sydney is impressive - but it seems they missed a bit?

Impressed with @intro so far. A new way (less-GLG-corporate-heavy-feeling) to get advice from experts. Some impressive names avialable for a fee e.g. founders of Zillow, Reddit

We've rolled out a new auto-memory feature. Claude now remembers what it learns across sessions — your project context, debugging patterns, preferred approaches — and recalls it later without you having to write anything down.
