# gst: periodic oscillations of flexible knots

AA << study the dynamics of knotted deformable closed chains sedimenting in a viscous fluid. (..) trefoil and other torus knots often attain a remarkably regular horizontal toroidal structure while sedimenting, with a number of intertwined loops, oscillating periodically around each other. (..) this motion (..) is accompanied by a very slow rotation around the vertical symmetry axis. (..) this oscillating mode of the dynamics can spontaneously form even when starting from a qualitatively different initial configuration. (..) the oscillating modes are usually present as transients or final stages of the evolution, depending on chain aspect ratio and flexibility, and the number of loops. >>

# biochem: how an artificial enzyme can convert solar energy into hydrogen gas

<< Hydrogen gas has long been noted as a promising energy carrier, but its production is still dependent on fossil raw materials. Renewable hydrogen gas can be extracted from water, but as yet the systems for doing so have limitations. In the new article, published in the journal Energy and Environmental Science, an interdisciplinary European research group led by Uppsala University scientists describe how artificial enzymes convert solar energy into hydrogen gas. >>

# brain: networks that may underlie our perception of free will

<< Our perception of free will is composed of a desire to act (volition) and a sense of responsibility for our actions (agency). >>

AA << study focal brain lesions that disrupt volition, causing akinetic mutism (..), or disrupt agency, causing alien limb syndrome (..), to better localize these processes in the human brain. >>

<< Lesion locations causing akinetic mutism all fell within one network, defined by connectivity to the anterior cingulate cortex. Lesion locations causing alien limb fell within a separate network, defined by connectivity to the precuneus. >>

AA << results demonstrate that lesions in different locations causing disordered volition and agency localize to unique brain networks, lending insight into the neuroanatomical substrate of free will perception. >>

# trade: deep transition scenarios in finance and banking through webtech

<< Good Money is a mobile-first banking wallet that allows users to hold all of their assets, both fiat and cryptocurrencies, in one place. The wallet has no annual fee ($0 per year vs. the average $400 per year of consumer checking accounts) and allows for full fiat and cryptocurrency interoperability. Further, Good Money offers a 1.8 percent interest rate - over 100 times greater than interest rates offered by traditional checking accounts. Beyond interest rates, a second failure of traditional consumer banking is that customers do not control how their stored money is invested by banks. Meaning that your money could well be invested in the petroleum industry when you are in fact a die-hard environmentalist. As the name implies, Good Money enables you as the user to choose how your stored money is invested, aligning it with your vision for humanity. >>

# evol: precision in work among Neanderthals

<< Neanderthals were also more similar to modern humans in their physical expression than previously thought. The study, which analysed Neanderthal hand and arm bones, reveals that these individuals didn’t actually rely primarily on force in their daily activities – they used precision grips just like we do. >>

# psych: a view around dark personalities, by Morten et al.

<< Egoism, Machiavellianism, narcissism, psychopathy, sadism, spitefulness and others are among the traits of the malevolent side of human personality. As results from a recently published German-Danish research project show, these traits share a common "dark core." People with one of these tendencies are also likely to have one or more of the others. >>

# evol: adaptability by genome duplications (A. kamchatica)

<< "With these results, we have demonstrated on a molecular-genetic level that genome duplications can positively affect the adaptability of organisms," says plant scientist Timothy Paape. The multiple gene copies enable the plant to assume advantageous mutations while keeping an original copy of important genes. >>
