# gst: more on the three-body problem (695 families of collisionless orbits)

<< The famous three-body problem can be traced back to Isaac Newton in the 1680s >>

In a recent paper AA << numerically obtain 695 families of Newtonian periodic planar collisionless orbits of three-body system >>

# zen: short daily mental practices induce structural plasticity in socio-affective and socio-cognitive brain networks

AA << have recently discovered that different types of mental training positively affect either our attention abilities or our social competencies such as compassion and perspective-taking. These improvements in attentional-, socio-emotional or cognitive capacities are parallelled by structural changes in dissociable brain networks supporting these skills. In addition, the scientists were able to show that the release of the stress hormone cortisol after exposure to a psychosocial stressor was significantly reduced only after practising mental techniques aiming at improving social competencies but not by mindfulness-based attention-increasing techniques >>

# brain: a unique patterns of activations during processing narratives

<< English, Farsi and Mandarin readers use the same parts of the brain to decode the deeper meaning of what they're reading >>

<< Even given these fundamental differences in language, which can be read in a different direction or contain a completely different alphabet altogether, there is something universal about what occurs in the brain at the point when we are processing narratives >> Morteza Dehghani.

<< In the case of each language, reading each story resulted in unique patterns of activations in the "default mode network" of the brain. This network engages interconnected brain regions such as the medial prefrontal cortex, the posterior cingulate cortex, the inferior parietal lobe, the lateral temporal cortex and hippocampal formation >>

<< One of the biggest mysteries of neuroscience is how we create meaning out of the world. Stories are deep-rooted in the core of our nature and help us create this meaning >> Jonas Kaplan.
