Microplastics likely reach Antarctic waters and ice via ocean currents and human activity, but data are sparse. Standardised sampling campaigns and analytical pipelines are required.

Warming may alter soil stability, hydrology, and microbial activity, affecting infrastructure and ecosystems. Long-term ground-temperature networks and modelling tools can track changes.

Old ice archives can extend climate reconstructions, but drilling and analysis are costly and complex. Improved drilling technology and coordinated core-analysis programmes can unlock more data.

Antarctic sea-ice changes influence deep-water formation and global heat and carbon transport. Coupled observations and models are essential.

Shifted Southern Ocean dynamics could trigger large-scale circulation changes. High-resolution Earth-system models and sustained observations are needed.

Surface meltwater can destabilise shelves in complex ways. Field experiments and high-fidelity models are needed.

Researchers keep finding creative ways to bypass safety filters built into AI systems, and defenses often lag behind the newest bypass techniques. This cat-and-mouse dynamic remains unresolved despite constant patching.

Astronomical observations demand extra unseen mass, but candidate particles from extensions of the Standard Model remain undetected. New detector designs, astrophysical surveys, and theoretical models are needed to pin down its nature.

Big Bang models suggest equal amounts of matter and antimatter, yet the observable Universe is dominated by matter. Precision measurements of CP violation and new physics at high energies could explain the imbalance.

Observations show billion-solar-mass black holes early in cosmic history, which standard growth models struggle to explain. Improved surveys of high-redshift quasars and simulations of direct-collapse scenarios are needed.

Solar flares, coronal mass ejections, and stellar winds shape atmospheric escape and habitability, yet models remain approximate. Continuous monitoring and improved magnetohydrodynamic simulations can refine predictions.

Grand unified theories predict proton decay, yet experiments have not observed it. Larger underground detectors and longer observation times are needed.

Oscillation experiments show mixing but leave ordering and scale uncertain. Next-generation beta-decay and cosmological probes can answer these questions.

Turbulence controls transport and heating but remains mathematically challenging. Laboratory plasma experiments and numerical advances are needed.

Their equation of state depends on poorly constrained nuclear physics at extreme densities. Multi-messenger observations of mergers and precise timing can narrow possibilities.

Alternative theories predict deviations that current experiments are only beginning to probe. More sensitive tabletop experiments are needed.

Mechanisms behind superconductivity in cuprates and iron-based materials remain contested. Combined experimental and theoretical work is needed to unlock room-temperature materials.

Observed exoplanet diversity challenges simple core-accretion models. High-resolution imaging of disks and improved simulations are needed.

Dust growth, fragmentation, and migration shape planet formation but are complex. Combined observation and modeling efforts are needed.

Galaxies stop forming stars due to feedback and environment, but mechanisms vary. Surveys across environments and redshifts can clarify.
