The rapid rise of large language models has fuelled speculation about eventual artificial general intelligence. Winner of the Brain Essay Competition 2025, Alex Gwyn O’Hare considers whether it is technologically feasible for machines to achieve human-level intelligence, and philosophically plausible for them to possess consciousness.

Polarization measurements for the optical counterpart to GRB 021004 are presented and discussed. Our observations were performed with the TNG and the VLT-UT3 (Melipal) during the first and fourth night after the gamma-ray burst discovery. We find robust evidence of temporal evolution of the polarization, which is therefore, at least partially, intrinsic to the optical transient. We do not find convincing evidence of wavelength dependence for the intrinsic polarization of the transient, in agreement with current polarization models for optical afterglows. We discuss the role of dust, both in our galaxy and in the host, in modifying the transmitted polarization vector, showing how a sizable fraction of the observed polarized flux is due to Galactic selective extinction, while it is not possible to single out any clear contribution from dust in the host galaxy. We discuss how our data compare to those obtained by different groups showing that a two-component model is required to describe the complete dataset. This is not surprising given the complex lightcurve of GRB 021004.

Traffic accidents are a major cause of death and disability, accounting for significant numbers of brain injuries. The purpose of this article is to discuss those conditions that can affect driver safety. The role of the nurse practitioner in primary prevention involves assessing the health status of drivers, including risk-taking behavior, age-related factors, use of alcohol and medications, and chronic illnesses and physical conditions that can result in driver impairment. Interventions can include patient education, anticipatory guidance, role-playing, referral for skill-building or driver evaluation, and reporting potentially unsafe drivers in keeping with state guidelines. Practitioner involvement in grass-roots community groups is encouraged.
