When you're doing two things at once - like listening to the radio while driving - your brain organizes itself into two, functionally independent networks, almost as if you temporarily have two brains. That's according to a fascinating new study from University of Wisconsin-Madison neuroscientists Shuntaro Sasai and colleagues. It's called Functional split brain in a driving/listening paradigm
In referring to 'split brains' in their title, Sasai et al. are linking their work to the litera... Read more »

Working for both public and private institutions, archaeologists constantly construct and deconstruct narratives about our past, but traditionally publish only a fraction of the sites they excavate and thus destroy. Computers and the internet present a vast range of opportunities for archaeologists to share primary data and foster intercultural online collaborations and reinterpretations of archaeological contexts. ...

One central concept in the OMA project and other
work we do to infer relationships between genes is that of Hierarchical
Orthologous Groups, or “HOGs” for the initiated.
We’ve written several papers on aspects pertaining to HOGs—how to infer
how to evaluate them, they being
increasingly adopted by orthology
resources, etc.—but there is
still a great deal of confusion as to what HOGs are and why they matter.

Where is the septum?
The term septum, when used in reference to the brain (it is a common anatomical term used to refer to a partition), indicates a subcortical structure in the forebrain that is found near the midline of the brain. The septum in humans can be separated into two structures: the septum pellucidum and septum verum. Each of these is sometimes........ Read more »

"Prescription drug use and polypharmacy rates among adults with ASD [autism spectrum disorder] are substantially higher than those in an age-, sex-, and race-matched cohort of adults without ASD."That sentence taken from the paper by Rini Vohra and colleagues  (open-access available here) is probably not likely to win any 'novel findings of the year' awards given the already quite voluminous data published on the medication use and autism (see here for example). What gives the ........ Read more »
