A Tiny Skew in the Atomic Nucleus and the Mystery of the Universe ⚡ экспресс
Original: "First Experimental Limit on the Permanent Electric Dipole Moment of the Deuteron"
Scientists set a strict limit on the electric asymmetry of nuclei, moving closer to solving the puzzle of the matter-antimatter imbalance.

Inside a giant magnetic ring, heavy hydrogen nuclei were spun, searching for a barely perceptible asymmetry. They didn't see it, but set a record for precision. Perhaps this very method will reveal where all the antimatter went after the Big Bang.
🎯 The sensitivity is like noticing a razor blade tilt by the width of an atom from a football field away.
🎬 In Isaac Asimov's 'The Last Question,' the theme of missing antimatter doesn't come up, but his science fiction is permeated with a sense of the universe's unresolved asymmetries.
|d^d| < 2.5 \times 10^{-17}\, e\cdot\mathrm{cm} \; (95\%\,\text{C.L.})
The magnitude of the deuteron's electric dipole moment is less than 2.5×10^-17 of the electron's charge times a centimeter, with 95% confidence.
