They learned V-formation flying from each other. National Geographic reports on some of the fascinating intricacies of the V formation observed in migrating birds.
Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.[more inside]
Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1.

Deciphering the Tools of Nature’s Zombies: The ability of parasites to alter the behaviour of their hosts fascinates both scientists and non-scientists alike. One reason that this topic resonates with so many is that it touches on core philosophical issues such as the existence of free will. If the mind is merely a machine, then it can be controlled by any entity that understands the code and has access to the machinery. This special issue of The Journal of Experimental Biology highlights some of the best-understood examples of parasite-induced changes in host brain and behaviour, encompassing both invertebrate and vertebrate hosts and micro- and macro-parasites. Full issue annotated inside: [more inside]
From the mid 40s to the mid 50s Coronet Instructional Films were always ready to provide social guidance for teenagers on subjects as diverse as dating, popularity, preparing for being drafted, and shyness, as well as to children on following the law, the value of quietness in school, and appreciating our parents. They also provided education on topics such as the connection between attitudes and health, what kind of people live in America, how to keep a job, supervising women workers, the nature of capitalism, and the plantation System in Southern life. Inside is an annotated collection of all 86 of the complete Coronet films in the Prelinger Archives as well as a few more. Its not like you had work to do or anything right? [more inside]
Nature constantly engineers new and creative solutions to all sorts of problems—turning our stereotypes about sex upside-down along the way.

As the market plummets, it might be interesting to look at the neurological background in the breakdown of trust. The author, Jonah Lehrer, is a young brainiac writer for Seed and the excellent Frontal Cortex. l Scientists immediately discovered a strong neural signal that drove many of the investment decisions. The signal was fictive learning. l One way to think of the financial markets right now is that instead of being populated by rational agents, they're full of people with borderline personality disorder.
