Ca₂RuO₄ is a Mott insulator that becomes a metal when a current is passed through it. Now, the changes in its electronic structure are revealed as this transition takes place.

Immune cells are believed not to generate large traction forces during migration. Now, measurements of natural killer cells in dense tissue reveal bursts of large traction forces as they move through narrow pores.

Deflection is one of the options discussed for preventing catastrophic collisions of asteroids with Earth. Now, a megajoule-class X-ray pulse is used to simulate such scenarios, demonstrating that it is a viable strategy at higher interceptor energies.

Coherent noise affecting a random error correcting code is now shown to produce a transition between phases that accumulate and destroy magic.

Rydberg atoms in optical tweezers are a promising platform for quantum information science. A platform composed of dual-species Rydberg arrays has been realized, offering access to unexplored interaction regimes and crosstalk-free midcircuit control.

The implementation of synthetic Abelian gauge fields in quantum simulators can result in chiral edge currents. The impact of non-Abelian gauge fields on chiral dynamics of ultracold atoms is now explored using a momentum-space lattice technique.

The Fisher information imposes a fundamental limit on the precision with which an unknown parameter can be estimated from noisy data, as Dorian Bouchet explains.

PhD students can face many challenges, such as a lack of confidence in their newly acquired skills or the uncertainty about which career path to choose. We highlight some ways to empower students in their doctoral journey.

Measurements pervade winemaking, from the size of vineyards to the taste in your mouth. Stefanie Reichert gives us the tour.

In light of the recent Olympic and upcoming Paralympic Summer Games in Paris, we take a closer look at the physics of sports and how it helps athletes improve their performance.
