I imagine that Brits trying to understand a fractured party system could look at Canadian political history.
Though recent Canadian history might suggest that party consolidation (at least under FPTP) is inevitable.

Could a “smoke alarm” for airborne contaminants monitor and improve the quality of the air indoors? (Where Americans spend 90 percent of their time!)
An interdisciplinary research team led by @linseymarr.bsky.social will create such a system that could cut respiratory illnesses by 25 percent. 👏

More data centres -> more F-gases -> more climate impact + more TFA #PFAS
The petrochemical industry is expanding production of PFAS in response to the data center boom, betting that the tech industry's toxic chemical releases face no serious prospect of regulation under the Trump regime. But campaigners know that the states have a powerful role.
Advocates raise alarm over Pfas pollution from datacenters amid AI boom
Tech companies’ use of Pfas gas at facilities may mean datacenters’ climate impact is worse than previously thought
