# esobio: Aliens & OoL, a review

AA << explores the collaborative nature and interdisciplinarity of the origin(s) of life (OoL) research community. Although OoL research is one of the oldest topics in philosophy, religion, and science; to date there has been no review of the field utilizing bibliometric measures. A dataset of 5647 publications that are tagged as OoL, (..) >>

# gst: the role of turbulence in the formation of self-organizing patterns

<< What part of the 'self' is responsible for the 'organization?' That role is performed by the unstable modes ('control modes') which alter the position and stability of the local equilibria that drive the time-evolution of the system >> Jacob Halatek

<< These turbulences (..) do not result in the complete loss of order (..) precisely the opposite occurs. When we destabilize the system, we observe that turbulence develops relatively rapidly. But upon further perturbation, the system undergoes a transition in which it is far from equilibrium, but nevertheless clearly ordered and non-turbulent >> Erwin Frey

# behav: cockroaches, more about

AA have found << that not only do cockroaches have unique individual personalities, but their differences can also have an impact on group dynamics >>

AA << suggests that varying degrees of personality differences in individuals is likely part of what allows cockroaches to adapt to new surroundings so easily. Brave individuals may forge a new path, while those that are shy remain behind, safe, should a nasty fate await those who venture out >>

Bob Yirka. Study shows cockroaches have individual personalities that impact group dynamics. Feb 4, 2015.

https://m.phys.org/news/2015-02-roaches-individual-personalities-impact-group.html

<< Many studies on collective behaviour underestimate the role of individual personality and, as a result, personality is rarely analysed in the context of collective dynamics. Here, [AA] show evidence of sheltering behaviour personality in a gregarious insect (Periplaneta americana), which is characterized by a collective personality at the group level >>

# evol: cockroaches, the most detailed information about their evolutionary history

<< As a widespread group of insects with a fossil record dating back 300 My, cockroaches provide an ideal model for testing hypotheses of vicariance through plate tectonics versus transoceanic dispersal >>

AA << analyses provide evidence that both vicariance and dispersal have played important roles in shaping the distribution and diversity of these insects >>

# chem: how to quickly wrap droplets with a splash to stabilize emulsions

<< Whether an object has a regular or irregular shape, wrapping it with a thin film can be challenging >>

Deepak Kumar, Joseph D. Paulsen, et al.  Wrapping with a splash: High-speed encapsulation with ultrathin sheets. Science. 2018; 359 (6377): 775 - 8. doi: 10.1126/science.aao1290. Feb 16, 2018.

http://science.sciencemag.org/content/359/6377/775

<< The quick and simple solution Kumar [Deepak Kumar] has found is a huge advance, and once he mastered it and identified the most important parameters, he found he could get adventurous and make different shapes. "We show that we have made cubes and a tetrahedron, for example" >>

<< If you want to add complexity, you could put a layer or a pattern on the inside of the wrapping, or you could add a window to make it slightly leaky. Once you know how to do the technique, it's not fussy. >>

# soc: just only one #POTUS Donald's (chaotic) tweet to change the course of California's 2018 elections, by John

<< Well, there's a guy who was supported by 76% of the party's voters in the PPIC survey. That would be Trump. And he's got an effective way to ensure a chosen candidate gets a ton of free attention. Yes, a presidential tweet. >>

<< The flip side, of course, is that an embrace from Trump could turn off millions of otherwise persuadable California voters. But for a party with limited options, firing up the voters you already have may be better than doing nothing at all. >>
