After weeks of playing together 30 minutes every night, the child finally beat her first video game and now is just walking around the house like Sad Pablo muttering "what do I do now" to herself.

The letter was submitted long before the current South Carolina outbreak, but data show Spartanburg (where the outbreak is centered) has experienced an increase in exemption rates for years.
Vaccine policies work even if you don't see the consequences of their destruction until years later.

In a new, timely project led by @nathanlo.bsky.social, we collected vaccine exemption rates (mostly) at the county-level for nearly all states.

Anytype is a local-first version of notion. If you go down the notion-esque route but want to be able to work without constant internet access, I'd consider it.

Last week, the child caught me doing The Mini crossword and asked me why I was doing "the duplo of crosswords". Now I only do the real NYT crossword until she falls asleep so I don't get shamed.

It's that time of the year again. The mornings have a crisp edge. The smell of hot PSLs fills the air. The NIH SROs are sending out their "what to do if a government shutdown happens" emails. Magic is in the air.

Excellent coverage of our study out today on climate impacts on wildfire smoke and related health impacts.
It's not your imagination: Wildfire smoke in the U.S. has dramatically worsened since 2019. According to a new study, it's already killing 41,000 people a year - and it's poised to get much worse.

Record wildfire smoke kills more people each year than car crashes. It’s about to get worse.
The past six summers have been the smokiest on record. New research shows that smoke could become the costliest consequence of climate change for Americans.
