TL;DR

NASA is staffing up and accelerating work on its first missions to Venus in a generation.
Quantum error correction has produced qubits that glitch only five times out of a million, advancing development toward a megaquops phase in computing.
Japan's MMX mission is preparing to launch a spacecraft to retrieve 10 grams of dust from Mars's moon Phobos and return it to Earth.
Winning entries from the 2026 Nikon Small World competitions reveal the hidden cellular interactions that govern everyday life.
A CAR T cell therapy from Kyverna Therapeutics could become the first FDA-approved treatment for stiff person syndrome.
The United Nations warns global warming will exceed 1.5 degrees Celsius, with the best-case scenario projecting a 1.8-degree overshoot requiring massive carbon removal.

Recent scientific and technological efforts are defined by exact numerical goals and physical boundaries. Science News's 2-minute article notes that quantum error correction now yields qubits that glitch just five times per million operations as engineers pursue a megaquops era. In space exploration, BBC News's 4-minute article reports that Japan's MMX spacecraft is scheduled to launch to collect 10 grams of dust from the Martian moon Phobos and return it to Earth. Meanwhile, Ars Technica's 6-minute article highlights the United Nations projection that global warming will exceed 1.5 degrees Celsius, with the best-case outcome reaching a 1.8-degree overshoot that demands massive carbon removal. Across these fields, progress relies on meeting rigid physical targets.
