One of the most important events in the history of the planet – an event that caused forests to turn into fields, skyscrapers to sprout from the ground, and footprints to appear on the moon. And we don't really know what drove it! Figure: https://theconversation.com/how-smart-were-our-ancestors-turns-out-the-answer-isnt-in-brain-size-but-blood-flow-130387 …pic.twitter.com/bdiA8o5uBr

An aluminium-foil boat floating in sulfur hexafluoride: a colourless gas that's heavier than air (and that makes your voice deeper if you breathe it in – it's basically the opposite of helium). https://www.reddit.com/r/ThatsInsane/comments/exjm2s/this_is_a_tin_boat_floating_in_sulfur_hexafluoride/ …pic.twitter.com/d7Fa3LKj9a

2- Other methods for estimating heritability don’t rely on the EEA, or on twins at all, but on random variation in the extent of genomic sharing between siblings. And guess what! Heritability doesn’t go away!https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1413498/ …

1- Twins are regularly misclassified by their parents & others, which creates an opportunity to test whether their phenotypic similarity tracks their actual genetic relatedness or their social identity as MZ or DZ. It’s the former (by

I can think of few things less “lively” than rehashing a conversation about the EEA, especially since twin studies are no longer the major workhorses of psychiatric genetics. BUT lest other people be confused that this is still actually a contentious issue....https://twitter.com/jayjoseph22/status/1224079641725435904 …

Another viral animal video that makes me wonder whether psychologists have been seriously underestimating the cognitive abilities of our furry cousins. https://www.reddit.com/r/likeus/comments/exiik2/this_area_over_here_is_better_for_baby/ …pic.twitter.com/aJejHbgf5l

An important study and inspiring finding on how to reduce bigotry by "deep canvassing" and giving people "grace," rather than anger or shame. From

1 fascinating study Klein quotes found that “priming white college students to think about the concept of white privilege led them to express more racial resentment in subsequent surveys.” Anti-racist indoctrination actually feeds racism—tribalism deepenshttp://nymag.com/intelligencer/2020/01/andrew-sullivan-america-needs-a-miracle.html …

A pufferfish deflating. When threatened, pufferfish rapidly suck in enough water to make themselves much larger and harder to eat: a great big inedible ball. As a backup plan, most also contain tetrodotoxin, which for humans is 1,200 times deadlier than cyanide. Cute, though!pic.twitter.com/sfOxGt3Ora

A man was sitting alone, on a bench in a park, singing Bon Jovi's Living on a Prayer by himself. By the end, the entire park joined along to sing with him. (

Natural selection builds mechanisms that human engineers still struggle to match. Exhibit A: The neural structures underpinning head stabilization in this hawk. (Head stabilization has the same function as image stabilization in cameras: to maintain a steady view despite motion.)pic.twitter.com/G5fGDdJrdk

A great way to realise the sheer quantity of information our
seamlessly processes when we do a “simple” task like driving a car.
This is what the Tesla autopilot sees using a neural network which took 70,000 GPU hours to train.

This is the kind of muddled conclusion people reach when they start thinking of groups of people as individuals, rather than focusing on actual individuals: It's OK for this woman to abuse this man because *other* men abused other women in the past.

Here’s a robust psychological effect that does not wilt under replication scrutiny. Kurt Lewin noticed it in the 1930s: making public commitments “freezes” attitudes in place. So saying something dumb makes you a bit dumber. It becomes harder to correct yourself. Tweeters beware.pic.twitter.com/cXoujA4VUY

The fact that hundreds of millions of people have been spared the agony of losing a child - or of dying themselves as children - is surely the single greatest humanitarian achievement of our species. https://books.google.com.my/books?id=xn83DwAAQBAJ&pg=PT73 …pic.twitter.com/LD17gu67P7
