This Perspective argues that the development of ⁹⁹Mo production methods complementary to reactor-based methodology is strategic in the short-to-medium term. Localized and resilient ⁹⁹Mo production routes might guarantee access to important diagnostic procedures even in the case of unpredictable global events.

Spatial dynamics can obscure epidemic trends from surveillance data, biasing reproduction ratio estimates over long periods. A spectral correction reweights incidence data to remove this bias, thus improving monitoring to inform response strategies.

Pulse tube refrigerators are a critical enabling technology for many disciplines that require low temperatures, including quantum computing. Here, the authors show that dynamically optimizing the acoustic parameters of the refrigerator can improve conventional cooldown speeds up to 3.5 times.

The best timepieces tend to be fragile, but a device based on iodine threads the needle between precision and practicality.

Stable regions in four-dimensional phase space have been observed by following the motion of accelerated proton beams subject to nonlinear forces. This provides insights into the physics of dynamical systems and may lead to improved accelerator designs.

Due to come online this year, the JUNO facility will help to determine which type of neutrino has the highest mass — one of the biggest mysteries in physics.

Increasingly, physics graduates take jobs outside academia. Active teaching approaches lead to deeper conceptual understanding and a more varied skill set and are therefore more likely to prepare students for successful careers.

An advanced light source for research would boost growth in the Greater Caribbean region — scientific, economic and societal.

AI needs to develop more solid assumptions, falsifiable hypotheses, and rigorous experimentation.
