Asking for a friend… But seriously, this is a real question. For example, several years ago, Herbert Weinstein tossed his wife out the window of their Manhattan apartment, after killing her, following an argument. He was well known to be a non violent person, and there was really no good reason for him to murder…

I’ve got this press release that will be of interest to many: An international team including researchers at the university of Edinburgh and Antoine Wystrach of the Research Centre on Animal Cognition (CNRS/Université Toulouse III—Paul Sabatier) has shown that ants can get their bearings whatever the orientation of their body. Their brains may be smaller…

Over 600 (as of this writing) neuroscientists from around the world, but with a very large proportion representing Europe, have written an open letter expressing concern with the Human Brain Project (HBP) and its cousin the U.S. BRAIN Initiative. It appears that the neuroscience community regards these projects as of relatively low value, while at…

A large scale model of a human brain has been created by a team of scientists at the Centre for Theoretical Neuroscience, University of Waterloo, Ontario. This is a virtual model, inside a computer, that involves 2,5 million virtual neurons structures in a pattern resembling the overall human brain’s anatomy, including cortical regions, motor control…

No new nose neurons?

Elizabeth Norton has an interesting write-up in Science Now. Some years ago, after a long period of suspicion, it was seemingly demonstrated that neurogenesis (the formation of new neurons) happened in the human nose. This research was based on the identification of proteins that would be associated with the early formation of baby neurons. Therefore,…

Falsehoods: Human Universals

There are human universals. There, I said it. Now give me about a half hour to explain why this is both correct and a Falsehood. But first, some background and definition.

The Oystercatcher and the Clam

One of those really cool and useful “evolution stories” gets verified and illuminated by actual research. And blogging!

Culture Shapes How We Look at Faces

Constructivism. Determinism. It is all a bunch of hooey. A recent paper published by PLoS (Culture Shapes How We Look at Faces) throws a sopping wet blanket on widely held deterministic models of human behavior. In addition, the work underscores the sometimes spooky cultural differences that can emerge in how people see things, even how…

Sometimes people walk around with only half a brain, or a large portion of their brain disconnected, or simply having never developed, or an extra large brain, and we usually take little notice. But when there is a five or ten or twenty percent difference between two groups of people we are quickly willing to…

The Synaptic Cleft Rap

Ion channels, chica. Hat Tip: Virginia Hughes. Who also has something interesting on Coffee.
