Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).
A crescent Moon seen during the day, arcing from upper left to lower right of the frame. At lower centre is the full disk of Jupiter; the small dots to its upper left and lower right and Io and Ganymede, respectively.

This really is SO good.
'It is certainly not a medical condition as far as I'm concerned" - Dr lona Heath Former President of the Royal College of General Practitioners
I don't doubt Dr Heath's contribution to medicine, but again, it's worth flagging up your focus on the 'modern' issue of excessive ADHD diagnoses, and the word former' regarding Dr Heath
Specifically, Dr Heath retired from clinica practice in 2010. She hasn't dealt with a patient in almost two decades. And while any decent doctor spends their whole career learning and developing as medicine advances. Dr Heath obtained her medical degree in the early 1970s, almost thirty years before ADHD was even recognised by the NHS, and almost forty years before it was first recognised in adultsThen there's the host. Dr Max Pemberton While entitled to his views, a psychiatrist who specialises in eating disorders and addiction isn't the obvious person to front a documentary about ADHD, which is neither of those things. It may also be worth noting his regular contributions as a writer to the Daily Mail and The Spectator. Again, being as diplomatic as possible, neither publication is known for 'ideological neutrality', which does suggest some external motivation beyond what is stated in the press release
In summary, when there are thousands of qualified experts, and hundreds of thousands of sources, who could provide a valid, up-to-date overview of the reality of ADHD in 2026, it's bizarre how you've managed to overlook literally all of them.

Hvor enn mye jeg avskyr radikal islam finnes det alltid en "silver lining": Hatefulle islamister er de eneste som klarer å få den mest bakstreverske delen av høyresiden i Norge til å bry seg om transpersoner, homofile og kvinnesak i en ukes tid.

Som med alle KI-modeller må man huske at de ikke er 100%. Særlig i møte med ukjente data. Gårsdagens hendelse er et eksempel på hvorfor vi ikke kan overlate beslutninger til KI-modeller. Menneskelig fornuft må alltid veie tyngst.

Western militaries have a systemic learning disorder. This is not a resource problem, nor an intelligence issue. It is a culture problem. They know what's happening in Ukraine and Iran, but are not adapting fast enough to the lessons from these wars. mickryan.substack.com/p/the-adapta...

'40% of the peak demand. And the build time was mere months. Given the rising demand in the whole country, only solar (18 months) and battery (12) can meet it in time. The "never solar" states are going to have a hard time as their pride proves to be costly' viaa Jonathan Hall
