There's a transcript of an informative discussion ("colloquy") on the whole math gender debate in the Chronicle of Higher Education; a radio program on the "oops center" (gotta love that name) - the part of the brain that recognizes our mistakes and, it now appears, also tries to prevent them; and a review in the Guardian of a new book by Steven Rose on the social implications of trendy neuroscientific research.

On a more academic note - well, in the sense of its expression (a media release rather than something meant directly for the layperson) - you can read about some fascinating new research aimed at investigating what brain systems determine why one individual is very comfortable expressing a need for help while another is much more restrained. All down to the amygdala (threat detection) and the right prefrontal cortex, which plays a role in reaching goals
and attaching to others. And Nature has a report on a recorder player who can taste differences in the intervals between notes!

And finally, here's a really weird one! I don't as a rule talk a lot about plant cognition (joke), but apparently a tiny plant known as strangleweed, can sense the presence of friends, foes, and food, and make adroit decisions on how to approach them. No doubt this, and more, will be discussed at the first conference on plant neurobiology, in May.
