0.5% to 3%: Do we now have a better sense of what makes people smart?

Posted 20 May 2014 / 0

The Economist “A potent source of genetic variation in cognitive ability has just been discovered” A new gene variant, KL-VS, appears to account for up to 3% of variation in IQ score; this would be a radical discovery given that past gene screens have only found variants accounting for as much as 0.5% variation in Read More

David Haig suggests that babies cry at night to prevent siblings

Posted 20 May 2014 / 0

Science News “Babies cry at night to prevent siblings, scientist suggests” What’s particularly interesting here is not just the parent-offspring conflict proposed but also the conflict between mothers and fathers that is implied in this theory. In fact, it seems that the only piece of evidence that has any potential to support this hypothesis is this Read More

Donald Trump saves CitiBike, proving that selfishness and cooperation are no longer opposed

Posted 01 Apr 2014 / 0

WNYC The Brian Lehrer Show “A New Citi Bike Savior: Donald Trump?” Although this story is disheartening, it truly is inspiring that so many enlightened and savvy New Yorkers called in to decry Donald Trump’s role in commercializing the previous-unsullied CitiBike Program.

Cognitive Ethology and Cat Companionship

Posted 17 Mar 2014 / 0

The Chronicle of Higher Education “Animal Magnetism” I still think that we would be appalled and offended if we could literally read the inner emotional dialogue of a cat, but I have to agree with the main contention of Barash and Lipton: that animals have feelings and connections with each other — and sometimes with Read More

Interesting numbers on the sustainability (or lack thereof) of the aviation industry

Posted 20 Feb 2014 / 0

Air Transport Action Group “Facts & Figures” I recognize that these statistics are being presented by an industry advocacy group, so they should be taken with some skepticism (I don’t have the time to fact-check them). But they are interesting, and damning enough of air transport (while also accenting our very strong dependence on this Read More

If sloths endure costs to maintain closed-loop agricultural systems, why can’t we?

Posted 05 Feb 2014 / 0

The New York Times “The Sloth’s Busy Inner Life” This is a great story about how paradoxical behaviors can be understood through appreciating mutualisms. If you don’t understand the benefits of algae to sloths and sloths to algae,  you can’t understand this behavior. But you also need to understand how sloths directly benefit moths and how Read More

Do we need to delete to keep the web sustainable?

Posted 05 Feb 2014 / 2

WNYC New Tech City “The World Would be a Better Place if We [DELETED] More” The title of this piece is a bit misleading, because on the cognitive side it is really unclear to me that forcing ourselves to memorize things would make our lives better (those who know me know that I am “anti-memorization”, Read More

String Theory: should we care?

Posted 02 Feb 2014 / 0

On Being “Reimagining the Cosmos” I always find myself stuck on the fence when it comes to the confrontation between physics and philosophy (and by extension religion). This episode effectively captures my ambivalence. On the one hand, I like that Brian Greene really sticks to his guns on the “sensation of free will”. If there Read More

Okay, I admit it: I am a bit of a Neanderthal

Posted 30 Jan 2014 / 1

The Economist “The genetic contribution Neanderthal man made to modern humanity is clearer” Although this article makes a bigger deal than it should about the “human construct” of the species concept (evolutionists are already well aware of the gradations of isolation that lead to full species separation), it presents these new findings in valuable context. What Read More
