Quantum's Problem Is Too Many Qubits, Not Too Few
Error correction works. That was settled this year. What nobody puts on a slide is the exchange rate: roughly a thousand fragile physical qubits to buy one reliable logical one, which lands a useful machine at millions of qubits against the few thousand that exist. A new family of codes published in Nature Communications claims to cut that ratio twenty-fold. Here is how, and the condition attached to it.

The Satellite Shaped Like a Dinner Plate
Small satellites have been built as cubes for twenty years, not for any reason to do with spaceflight but because that is the shape of the dispenser that pushes them out of the rocket. Four spacecraft shaped like dinner plates, a metre across and 2.5 centimetres deep, have now spent six months in orbit testing the alternative. The prize is very low orbit, where cameras see more and signals travel faster. Here is why shape decides who gets there.

Cement's Carbon Problem Gets Easier If You Never Let Air In
Concrete is the most used material on Earth after water, and making it releases carbon dioxide twice, once from the fuel and once from the limestone itself. No amount of clean electricity fixes the second one. A plant in Germany changed the order of operations instead, and the result is a waste stream concentrated enough to be worth something. Here is how it works, and the number nobody has published.

Featured today : A Crowded Sky
Orbital surveillance stopped being a state monopoly and became a product. States still fly their satellites, but a parallel commercial layer now sees the same ground and sells the view. The power moved from the hardware to the feed.

Two Bodies Flew Around the Moon. One Wore a Vest.
Two bodies flew around the Moon on Artemis I and came home. Neither was alive. Both were female. One was wearing a shielding vest and one was not, and the difference between them is now the best evidence we have on keeping people alive in deep space. Here is what the experiment showed, and what it cannot fix.

The Immune Cells Gene Editing Couldn't Reach
Macrophages decide what your body attacks, and their verdicts sit underneath arthritis, artery disease and the wall that keeps immunity out of a tumour. Gene editing largely skipped them, because the standard way in kills them. A new delivery vehicle changed that, and the first large genetic screen ever run in these cells has already turned something up.

The Frontier Week Ahead: Six Deep Dives, One a Day
Six days, six long-reads from the frontier, plus a featured story on orbital surveillance going mass-market. A quantum sensor that can touch a patient, gene editing reaching a cell it never could, and two bodies flown around the Moon.
