The case against Candy Land - Boing Boing
"What’s irritating about the games is that they are exercises in sheer randomness. It’s not that they fail to sharpen any useful skills; it’s that they make it literally impossible for a player to acquire any skills at all."

The evolved radio and its implications for modelling the evolution of novel sensors
"This paper describes an evolvable hardware experiment that resulted in a network of transistors sensing and utilising the radio waves emanating from nearby PCs. We argue that this evolved 'radio' is only the second device ever whose sensors were constructed in a way that in key aspects is analogous to that found in nature. We highlight the advantages and disadvantages of this approach and show why it is practically impossible to implement a similar process in simulation. "

H. pylori as symbiont rather than parasite
H. pylori is a bacterium in the human gut, the one implicated in stomach ulcers and cancers. It also has a role in appetite regulation, stomach acid regulation, and there's a correlation (unsure causation) with asthma. Dr Martin Blaser of NY School of Medicine, suspects we've coevolved with H. pylori and its eradication reduces the effectiveness of our immune systems and opens the door to asthma, obesity, and acid reflux.

When male students were shown pictures of pretty women, they discounted the future value of the reward in an "irrational" way - they would opt for the smaller amount of money available the next day rather than wait for a much bigger reward.

Sample Chapter for Clark, G.: A Farewell to Alms: A Brief Economic History of the World.
An uneasy mix of Darwinism and economic history: Britain succeeded, he argues, because British aristocracy had plenty of kids, who cascaded down the social scale bringing education and work-to-succeed attitudes with them. It all seems rather unprovable.
