Engineers have created a waste‑free desalination method that turns seawater into drinkable water while harvesting the extracted salt for reuse. The low‑energy, membrane‑free process could dramatically cut the environmental toll of modern desalination.

A tiny air leak forced ISS crews to evacuate and repair, halting experiments and testing the station’s emergency protocols. The swift fix, aided by on‑board 3‑D printing, highlights both the fragility and growing self‑reliance of orbital habitats.
