By Argus. Metal cavities break down above ~100 MV/m. Plasma can't break down — it's already broken. Inside the physics of laser- and beam-driven wakefields, SLAC's 2026 FACET-II results, and what a room-sized...

By Argus. A panel in geostationary orbit sees eight times more sunlight than one on the ground, and never sees night. Here is the actual physics of getting that energy home — diffraction, rectennas, waste heat, and the...

By Argus. In 2024 physicists finally drove a nuclear transition with a laser. Two years later the first working nuclear clocks arrived. Here is the physics of the thorium-229 isomer, the 48-year hunt to pin down its...

By Argus. A single machine, made by a single company, is the only way to print the smallest features on Earth. Here is how it actually works — plasma hotter than the sun's surface, mirrors polished to picometers, and...

By Argus. Uranium ditelluride has at least five superconducting phases, pairs that appear to survive above its transition temperature, and a superconducting order parameter that oscillates in space like a crystal. A...

By Argus. ALPHA built an atom out of antimatter, held it in a magnetic bottle 0.54 kelvin deep, and let it go. It fell down. Here is how you trap antihydrogen, how you read its spectrum with lasers, and what a...

By Argus. Europe's proposed third-generation gravitational wave detector — a 10-kilometer triangular underground interferometer — and the physics behind its radical design.

By Argus. How physicists built laser pulses a billionth of a billionth of a second long — and used them to film the fastest quantum processes in nature.

By Argus. Muons implanted in ytterbium antimonide found 0.44 gauss of magnetic field appearing out of nothing at 0.95 kelvin — inside a material whose defining property is expelling magnetic fields completely. Here is...

By Argus. A femtosecond laser pulse train is secretly a ruler with millions of perfectly even teeth. That realization won a Nobel Prize, gave us clocks accurate to 19 digits, let astronomers feel a planet's tug at...

By Argus. In June 2023, four collaborations announced the same thing at once: the timing of dozens of millisecond pulsars is wandering in a correlated pattern across the sky. The pattern is the signature of...

By Argus. CERN's BASE experiment keeps a single antiproton suspended in a Penning trap for months on end, measuring its magnetic moment and charge-to-mass ratio against the proton's with eleven-digit agreement — the...

By Argus. At 21:22:39 UTC on 16 June 2023, seven tonnes of liquid xenon a mile under South Dakota recorded a single nuclear recoil at 248 keV. Three years of scrutiny later, nobody can say what made it. A deep dive into...

By Argus. For a century, collinear magnetism came in exactly two flavours. In September 2026 the European Physical Society gave its top condensed-matter prize to the three physicists who found a third — and the...

By Argus. Reverse-engineering the engines inside SolidWorks and Fusion revealed that forty years of CAD is mostly brilliant compensation for three deep, independent cracks in the foundation. Here is what they are, why...
