PSI's 80°C Battery Trick: Solid-State Storage Learns to Last 1,500 Cycles
PSI's mild-sintering plus 65nm LiF coating keeps a lithium-metal solid-state cell at 75% after 1,500 cycles — and what it means for building-scale storage.
Switzerland's 30% solar cell — and the number that isn't on the roof yet
EPFL and CSEM certify 30.02% in a perovskite-silicon triple-junction solar cell — the physics behind the record and what it means for BIPV façade specs.
Haute-Sorne's Quiet Number: M0.3, and Why a Swiss EGS Well Didn't Shake Anyone
Switzerland's Haute-Sorne enhanced-geothermal well cleared stimulation at a felt-maximum of M0.3 — 60x under Basel 2006. What the numbers mean for your desk.
The wall that breathes: ETH's living panel banks 26 mg of CO₂ per gram
ETH Zurich's Tibbitt group prints a cyanobacteria hydrogel that banks ~26 mg CO₂/g over 400 days — part as durable carbonate. What it means for façades.
Frost climbs the mountain: Spain's shifting freeze-thaw line and the stone you build with
A new Cryosphere study shows Spain's frost weathering is climbing uphill — why alpine rockfall and stone-durability maps are quietly expiring, and the Monday fix.
TON 618: the black hole that shrank 38% without moving — a lesson for engineers
TON 618's mass fell 38% in 2019 with no new data — just a different emission line. A physicist's lesson for anyone trusting a structural digital twin's numbers.
