A new study suggests that populations of artificial intelligence (AI) agents, similar to ChatGPT, can spontaneously develop shared social conventions through interaction alone. The research from City St George’s, University of London and the IT University of Copenhagen suggests that when these large language model (LLM) artificial intelligence (AI) agents communicate in groups, they do not just follow scripts or repeat patterns, but self-organise, reaching consensus on linguistic norms much like human communities. The study has been published today in the journal, Science Advances.
Members of socially and economically marginalized groups in Montreal and Ottawa-Gatineau are at disproportionate risk in earthquakes, a new study has found.
Co-authored by McGill civil engineering professor Daniele Malomo, the study is the first in Canada to examine earthquake vulnerability through the lens of equity.
The researchers used spatial mapping and statistical techniques to identify where earthquake risk and social vulnerability intersect, revealing patterns of inequality tied to race, income, language and housing conditions. They drew their data from the 2021 Canadian Census and Canada’s Probabilistic Seismic Risk Model.
A recent study by the University of Turku and the University of Helsinki in Finland and the Finnish Social Insurance Institution Kela reveals that the average duration of ADHD medication for children and adolescents is more than three years. However, reliable, controlled data on the safety of marketed ADHD medicines in children are available for only one year of follow-up.
A research group led by FUJINO Misako and HARUNO Masahiko at the National Institute of Information and Communications Technology (NICT), has demonstrated that experiencing active flight in VR allows individuals to predict that they can transition to a safe state even if they fall from a height, thereby reducing fear responses. This discovery challenges the traditional understanding that fear extinction necessarily requires repeated exposure to fear-inducing stimuli.
In this study, the researchers compared a group of participants who actively experienced low-altitude VR flight (Flight Group) with a control group who passively watched recordings of the flight experience. The Flight Group showed significantly greater reductions in both physiological (skin conductance response, SCR) and subjective (self-reported fear score, SFS) fear responses when walking on a virtual plank at high altitude compared to the Control Group. Furthermore, among the Flight Group participants, those who more strongly felt "I can fly, so falling is not dangerous" exhibited a greater reduction in fear responses.
These results suggest that "action-based prediction" can reduce fear responses without relying on repeated exposure, potentially offering a new approach to fear extinction.
The findings were published online on May 13, 2025, in the Proceedings of the National Academy of Sciences (PNAS).
