A method for imaging spin waves in magnetic materials uses flash-like intensity variations in a laser beam to capture the wave motion at specific moments in time.

A theory outlines an immunization protocol that fosters powerful antibodies while avoiding immune-cell death.

An independent analysis of data on the hotly debated superconductivity of certain hydrogen-rich compounds, or hydrides, concludes that the phenomenon is likely genuine.

New experiments with cuprate materials explore a connection between so-called charge-density waves and a light-induced state that resembles superconductivity.

A laser-driven electron accelerator delivers beams of $\sim$10-GeV electrons—an approach that could lead to cheaper, more compact alternatives to large-scale x-ray sources and particle accelerators.
