Flying academia's flag for Japan, with a nod to the U.K. Mari Sako has adopted the idea of being a 'global citizen' through her work in academia.

“everything was relative — there was no absolute standard of how things worked: "The key is not necessarily feeling completely comfortable, but understanding why these differences exist."

A couple tried for 18 years to get pregnant. AI made it happen | CNN After trying to conceive for 18 years, one couple is now pregnant with their first child thanks to the power of artificial intelligence.

Great example of where AI gets all the credit but the ACTUAL contribution (in this case, sperm for fertilisation) was from the human. AI helped. It helped a lot. But without the human, AI would be impotent. Good allegory here.

The seagulls have landed: why gulls are encroaching on Britain’s towns Avian invaders have coastal communities in Britain and beyond in a flap – but people are learning how to live with them

“If it can seem at times that seagulls are taking over British towns, the fact is that their numbers aren’t rising at all – they are falling sharply. In some traditional coastal nesting sites, the most recent national seabird census found, the populations have all but collapsed”

“The lesson from abroad is clear: lasting change requires transforming the conditions that make parenthood feel untenable, not just offering token incentives.”

The politics of pronatalism and the two-child benefit cap - British Politics and Policy at LSE Nigel Farage supports the scraping the two-child benefit cap as a way of encouraging people to have more children. But pronatalist policies that offer a one-off "baby bonus" are not effective.

Another excellent piece from a demographer, this time Stuart Gietel-Basten, on how "pronatalism is a dead end"

"Without addressing the root causes of low fertility—inequality, instability, and the incompatibility of work and family life—top-down efforts to “encourage” childbearing will fail"

Farage wants a British baby boom – but he’s missing a trick Reform UK has moved into pro-natal policies territory – but experts warn there’s no magic silver bullet

👶 #Farage wants a UK baby boom — will it work? 🍼

Our Director @melindacmills.bsky.social says: “Throwing money at it doesn’t work.”

Tax breaks ≠ baby boom.

Work hours, #housing, #childcare — it takes an ecosystem.

Monday briefing: What Nigel Farage’s new obsession with nativism could mean for the UK In today’s newsletter: Reform’s latest policy shift echoes strategies seen in Europe’s far right. Will this approach gain traction in the UK?

Over the weekend, BBC Radio 4’s Any Questions programme - not typically a bastion of far-right values - included uncontested claims of how “low birthrates are the biggest problem the UK faces”. Worrying how quickly this view, rejected by experts in demography, is becoming mainstream
