ok so I went down a rabbit hole on sweat cortisol wearables and I think I accidentally ruined them for myself
you know the patches and watches that claim to measure your cortisol through your skin?
they have a problem. a big one. and nobody's talking about it.
Hold tight
"ok but surely the sweat still correlates with blood cortisol?" - kinda. barely.
a 2025 kinetic modeling study tried to correlate sweat cortisol to blood cortisol. raw correlation: ~0.6
for context, that's the correlation strength of "probably, maybe, sometimes"

I’m thrilled to announce we’ve raised $44M to build a new home for product design. Meet @noondesign.
No workflow is more broken and fragmented in 2026 than the product designers’. The very same people who care most about building software don’t have software purpose built for them. @kushagrasinha7 and I have lived this problem first hand as designers ourselves.
That’s why we built Noon. The first product design tool that works entirely on your product code, so you can design not only how a product looks, but also how it works. With AI at its core that works in seconds, not minutes.
For the first time, you can create, iterate, build, test and ship. All in one canvas. No translations or roundtrips to the codebase and back.
Comment “Get Noon” and we’ll get you on the list for early access.

Looking for a room in Bangalore!
Hey everyone, I'm on the hunt for a room in an existing house/flat (or a 1RK) in Bangalore. Here's the deal:
📍 Areas: HSR Layout, Koramangala, Indiranagar, or Sarjapur Road
💰 Budget: Up to ₹30,000/month
🪑 Furnished preferred
💻 Need a decent workspace at home
☀️ Big windows, natural light, and airflow is MUST
🌊 Brownie points if it's near a lake
🎸 Would LOVE a place with musicians or pet-friendly housemates
It is unsettling to realize that we know more about what’s happening on the Moon in real time than in our own bodies.
At every knowledge point when we wish to achieve the said objective, there is one crucial step where we need to first perceive the current state and interact with the built technological system to achieve the objective.
