Young adult happiness is falling. Percent of young people who are pretty or very happy has dropped from 88% to 76% over the last 15 years after having held fairly steady between 1980 and 2010

Young adult happiness is falling. Percent of young people who are pretty or very happy has dropped from 88% to 76% over the last 15 years after having held fairly steady between 1980 and 2010

My hottest “I have no data to back this up” take is that phones aren’t making young people less happy. What’s making them less happy is living in a world where everyone is having their reality defined by recommendation algorithms that can only care about whether something keeps you watching.

The Moon is tidally locked so one side always faces us.
From that side, Earth is a permanent fixture in the sky 13 times larger and 43 times brighter than the Moon appears from Earth.
Four humans photographed this.
Every crater in this frame is older than any life on land.

The Met Office announce that Storm Dave has been named. The background photo is of the sea, looking appropriately moody. Because Dave’s like that.

Particularly alarming that this includes Lebanon & Gaza. I had just shared imagery from March 18 showing the demolition of villages along the southern border of Lebanon by the IDF and now not even that imagery is available: bsky.app/profile/godi...

Mass demolitions haven't stopped in Gaza, either.

NASA aren’t on here (presumably US gov agencies have to only use channels loyal to their great leader) - but the European Space Agency is, and is sharing key updates on the Artemis mission…

Cordon Sanitaires and Purity Spirals What the rise in antisemitism teaches us about radicalisation

New post just out:

"Cordon Sanitaires and Purity Spirals"

Graph showing renewables overtaking fossil fuels

For when someone tells you everything is irredeemably broken - tell them that the EU produced more electricity with renewables in 2025 that from fossil fuels. And the trend is accelerating (especially after the current oil / gas price disasters).
