Here’s your weekly round-up of fun and fascinating:
To start with, I did a 6-part series on numerical cognition and the development of math skills, here and at Child’s Play:
1. The Developmental Origins of Numerical Cognition
2. What is Dyscalculia? How Does It Develop?
3. Developmental Dyscalculia Explained: Strategy, Memory, Attention
4. Numbers on the Brain: Neurobiology of Mathematics
For an evolutionary perspective, there were the two companion pieces this week here:
From Lucas Brouwers, a good explanation of why the term “living fossil” just doesn’t make sense.
Why did humans evolve the capacity to imagine alternatives to reality? From the NY Times Opinionator blog.

And a piece by Ferris Jabr: can a stroll in the park replace a psychiatrists couch? (Maybe not, but if you ignore the headline, its a great article.)
Why doesn’t it get warm when it gets windy? From Chad at Uncertain Principles.
From Razib at Gene Expression: some good background on genetics and Mendelism.
What can moose (mooses? meese?) tell us about arthritis?

Are we still writing about Pepsi? At Ars Technica they are.
Some thoughts from John Pavlus after a meet-up with Virginia Heffernan.
Not science, but interesting
Some California history via the LA Times: “Nathan Mendelsohn, a professor turned developer, believed California City would become the state’s next metropolis. Instead it’s a sleepy outpost that exists largely in the imagination.”
“How Food Works” from TLC Cooking. Seems like some good culinary science.
How online dating really works, according to a former Match.com researcher.
