# brain: lizard, an ancient dreamer (2)

<< Reptiles have a brain area previously suspected to play a role in mammalian higher cognitive processes, and establish its role in controlling brain dynamics in sleep. >>

<< The fact that we find a claustrum homolog in reptiles suggests that the claustrum is an ancient structure, likely present in the brains of the common vertebrate ancestor of reptiles and mammals, (..) While our results have not answered the question as to whether the claustrum plays a role in consciousness or higher cognitive functions, they indicate that it may play an important role in the control of brain states (such as in sleep), due to ascending input from the mid- and hindbrain, to its widespread projections to the forebrain and to its role in sharp-wave generation during slow-wave sleep, >> Gilles Laurent

# gst: apropos of 'wobbly' entities

<< As Earth rotates along its axis, it wobbles a little bit. This wobbling comes, in part, from how mass is distributed across the planet. Nuclear physics researchers have now observed this same type of wobbling in Au187-a gold isotope that lives for just eight minutes.  >>

# behav: how (and when) multiple bird species fly and feed together, like a K-pop band

<< Birds of a feather don't always flock together: Peer into a forest canopy, and you will likely spot multiple bird species flying and feeding together, a phenomenon most spectacular in the Amazon where 50 species may travel as a unit. But are birds in these mixed flocks cooperating with one another or competing?  A new study suggests both. >>

<< Species kept competition within the flock low, however, by differentiating their foraging technique, their choice of hunting spot or the general distance they kept from a tree trunk. >>

# gst: sand dunes 'communication' via turbulent swirls

<< Even though they are inanimate objects, sand dunes can 'communicate' with each other. A team (..) has found that as they move, sand dunes interact with and repel their downstream neighbours. Using an experimental dune 'racetrack', (they) observed that two identical dunes start out close together, but over time they get further and further apart. This interaction is controlled by turbulent swirls from the upstream dune, which push the downstream dune away.  >>
