Here is a round-up of headlines to ruin your weekend all at once, instead of ruining your week one day at a time, the DT Friday Freakout:
- Because of volatile chlorination byproducts, do not pee in the pool. [amer. chem soc via someone]
- Disproportionate suspensions and other harsh educational discipline of African American kids begins in preschool. [nyt]
- Donald Trump tweets that vaccines cause autism. [@actuallypjh]
- The New England Journal of Medicine published a study that found autism-linked anomalies in the neocortex which develops in the third trimester. Before birth. [nejm.org]
- The NHTSA is demanding Graco recall 1.8 million infant car seats, in addition to the 4.2 million it has already recalled this year [pdf], because they have similar impossible-to-open-in-an-emergency buckles. Graco's resisting, because the new batch has handles and bases and stuff, so you can just take the whole thing, why would you need to unbuckle anyway? Sheesh. [nyt, nhtsa.dot.gov, which still only publishes pdfs? what?]
- Actual knowledge is a more effective motivator for preschoolers than random sticker rewards, a study finds. Teachers shared information about a picture as a reward for kids completing a mindless, irrelevant task. I'm no educational researcher, but maybe an actually relevant task would be even more effective? Just a guess. [edweek]
