Apparently I should stop holding my breath for the Google Translate “dolphin” module

The Chronicle of Higher Education “Dolphin Talk and Human Credulity” Great short here (and further evidence that TED Talks entice scientists to lose their heads and say unfounded things). Anyone who has carefully watched a child learn to talk comes to realize what a complex dance between cognition anatomical coordination is involved in language acquisition. It is Read More

Is “nest parasitism” really “nest mutualism”?

Posted 20 May 2014 / 0

NPR All Things Considered “This Freeloading Bird Brings Help — And The Help Smells Gross” It is hard to believe that feeding an entire extra non-offspring would be in the self-interest of a bird, but as this short points out, costs and benefits are always environment-specific. In this case, the “parasitic” effect of having to raise Read More

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

There’s No Such Thing as Qualitative Sustainability

Posted 16 Apr 2014 / 1

Thinking green is just not enough It was one of those classic moments where the irony just seemed too severe to be unplanned. I was riding my bike to work when I passed a parked vehicle and noticed a remarkable bumper sticker. I still regret not taking out my phone and snapping a picture; because 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

I receive funding to initiate the WmD Project

Posted 06 Mar 2014 / 2

It seemed like a proposal with a dim chance of being funded, but on a bizarre whim of inspiration I decided to apply for a small bit of money so I could initiate a new creative venture that I am calling the WmD Project. It turns out that Pratt’s Faculty Development Fund has a bit 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
