What If Every Product Had a Disassembly Time?
A repairability score can hide the obstacle that decides whether repair happens: access time. A small teardown audit could turn that friction into a public design signal.
Alkemata Morning Press Review — 27 October 2026
Four evidence-led developments on endometrial-cancer treatment, hospital cyber resilience, Temu’s EU safety plan and Spain’s data-centre rules.
The Controller That Removes a Delay Without Making Anything Faster
A Smith predictor lets a controller act on a model's immediate response while correcting it with delayed measurements. The clever subtraction, its mathematics, and where it fails.
The Best AI Meeting Note May Be the One That Expires
AI meeting tools turn one conversation into several durable records. An expiry ladder can preserve decisions and accountability without keeping every utterance forever.
The Glass Fiber That Measures Strain by Shifting a Reflection
A tiny periodic pattern written into optical fiber reflects one infrared wavelength. Stretch the glass and that wavelength shifts—turning light into a remote strain gauge. Here's the Bragg physics, the…
Backstage at Alkemata: Growing, Learning, and Trying Things Out
A personal note from rdi on Alkemata’s gradual growth, our learning curve in marketing, experiments with AI and the Exchange, and a forthcoming series on psychology.
The Coating That Removes a Reflection by Creating Another
A transparent film about 100 nanometres thick can cut glass reflection by a factor of three. The trick is to arrange two reflected waves to cancel rather than absorb the…
A Bench Can Extend the Reach of a City
A public bench is more than street furniture. Its location, spacing and design can determine who can walk to shops, transport and public life—and who must turn back.
Why Strong Beams Put Material at the Edges
A beam’s strength depends not only on its material but on where that material sits. The I-section turns distance from the neutral axis into stiffness—and exposes new failure modes.
Two Slow Delay Lines Can Measure a Picosecond: The Vernier Timing Trick
A Vernier time-to-digital converter measures intervals far shorter than a logic gate's delay by racing signals through two nearly matched paths. Here is the physics, the arithmetic and the catch.
