**Spaces of Hybridized Prefatory Extremism (HYPE) on Social Media**

"_While extremism is usually perceived to be a matter of extreme ideologies and methods, social media enables and shapes distinct hybridization processes by which conspiracy beliefs, personal grievances, and various ad hoc convictions are combined with ideology fragments, consequently producing new extremist narratives._"

**Morphodynamic Foundations of Sumer**

"_We propose that tidal irrigation offers a plausible jumpstarting mechanism for high-yield, diversified agriculture providing an impetus for urbanization. As access to sea was restricted by delta build-up and tides shifted with the advancing deltaic coast, intensified reliance on mercurial river regimes eventually led to the expansive fluvial irrigation network of Early Dynastic city-states._"

**Gold is losing its lustre as a safe investment, research finds**

"_Professor David McMillan, Professor of Finance and Head of Accounting and Finance at Stirling Business School, said: “Our analysis found that gold started to lose its position as a safe haven during volatile periods. Platinum is the only precious metal to show a statistically significant safe haven role during extreme market shocks in the stable and volatile periods."_"

🖥️ 🇦🇺 **‘Australiana’ images made by AI are racist and full of tired cliches, new study shows**

"_We found when generative AIs produce images of Australia and Australians, these outputs are riddled with bias. They reproduce sexist and racist caricatures more at home in the country’s imagined monocultural past._"

"_The evidence reveals that the more users rely on AI to perform work for them, the less they see themselves as drawing upon their own thinking capacities. A study employing EEG measurements found different brain connectivity patterns when participants enlisted AI to help them write an essay than when writing it on their own._"

**Five thousand years of inequality in the Carpathian Basin**

" _We find that although farming did increase the potentials for both relational and material inequalities, the potential was rarely reached and then only for short durations. We identify a series of leveling mechanisms varying over time, including the removal of material wealth from circulation through the placement in graves, community fission, and investments of surplus labor in infrastructural investments._"

**New research dispels myth of conspiracy theorists as isolated outsiders**

_Co-author Professor Robin Canniford, also from Bath’s School of Management, said: “The participatory aspect of conspiracy theories encourages people to become involved. It can feel very positive and supportive. It’s a thriving and welcoming social scene where people feel they are better informed about the workings of the world and are ready to take action.”
