Parenting is effortful.
There are 168 hours in each week.
Parents of children in the first 3 years of life provide an average of 156 hours of care a week.
Allowing parents to parent less enables them to parent better.

Without intervention, higher income is strongly associated with higher car dependence across ~800 cities; doubling income ~37% more car journeys.
Electrifying a car-dependent city still means congestion, space, safety risk, and asphalt eating your budget.

It can be hard to trust a commercial provider, if their business model is exploitation of that trust.
Same product. Same store. Same time. But on Instacart, different customers may see different prices.

Does it matter at what age a child experienced the COVID shock for subsequent learning?
Eileen Powell and I have taken a first stab by looking at math and English proficiency by grade cohorts. The answer: yep.

A new record - on 5 December wind power produced enough electricity for 3/4 of UK homes
At 23.8GW it meant that even during winter peak demand, it was still providing nearly half the country's power needs

Further evidence that widespread covid vaccination is better for everybody.
A study on 1.7 million people in Hong Kong shows superior hybrid immunity to Covid in people who got vaccinated before infection vs. people who got infected first. "Our findings are a direct rebuttal to arguments for natural immunity," the authors write. doi.org/10.1016/j.va...

Rachel Reeves says there’s a “hole” in the public finances.
A new decade-long Brexit study explains it:
a 6–8% hit to GDP – that's £180bn-£240bn a year – means less tax, less investment and less money for everything else.
Brexit made Britain poorer. Much poorer.
