# behav: intriguing wolves, prosociality among wolves (compared to dogs)

<<  Prosociality is important for initiating cooperation. (..) In a prosocial choice task, wolves acted prosocially to in-group partners; providing significantly more food to a pack-member compared to a control where the partner had no access to the food. Dogs did not. Additionally, wolves did not show a prosocial response to non-pack members, in line with previous research that social relationships are important for prosociality.  >>

# soc: computational socioeconomics, a brief manifesto.

AA << will make a brief manifesto about a new interdisciplinary research field named Computational Socioeconomics, followed by detailed introduction about data resources, computational tools, data-driven methods, theoretical models and novel applications at multiple resolutions, including the quantification of global economic inequality and complexity, the map of regional industrial structure and urban perception, the estimation of individual socioeconomic status and demographic, and the real-time monitoring of emergent events. >>

# tech: apropos of peripheral neural interfaces; the AlterEgo 'second self'

<< AlterEgo is a  non-invasive, wearable, peripheral neural interface that allows humans to converse in natural language with machines, artificial intelligence assistants, services, and other people without any voice-without opening their mouth, and without externally observable movements-simply by articulating words internally. >>

<< AlterEgo seeks to combine humans and computers—such that computing, the Internet, and AI would weave into human personality as an internal "second self" and augment human cognition and abilities. >>

# psych: exploring trust among politicians

<< The new research, (..) tested a vulnerability-centered definition of trust-meaning, defining trust as a willingness to be vulnerable to the actions of another. The results revealed three assessments that lead to one trusting in the government: whether it has the ability to do its job, the benevolence to care about its people and the integrity to generally do the right thing. >>

# math: squeezing Moebius strips using either 'tame' or 'wild' embeddings, but only with overlaps

<< In math, three-dimensional space sprawls out to infinity in every direction. With an infinite amount of room, it should be able to hold an infinite number of things inside of it - pearls, peacocks or even planets. >>

<< But a recent proof (..), shows that one relatively well-known mathematical object can’t be packed an uncountably infinite number of times into an infinite amount of space: the Möbius band, a two-dimensional loop with a half-twist. >>

<< "Tame" embeddings extend to the entire space, so it’s possible to stretch or squish the space to make the embedded sphere into a standard round sphere. >>

<< "Wild" embeddings, on the other hand, are not so easily visualized and generally require some infinite process to describe. With a wild embedding, there is no way to transform the space to make the wildly embedded version a round sphere. >>
