# soc-eu: Bavarian Greens could be the second party (18% by exit polls)

<< Now, multiple surveys show the Greens polling at 15-17 percent nationally, catching up with or even overtaking the SPD. >>

<< The Green wave: Glance casually at the election results in Bavaria, in Luxembourg, in Belgium’s communes, and you’ll find a Green wave engulfing the center-left of the political spectrum. Look a bit closer, and you’ll see the traditional political camps - the EPP and Social Democracy - fighting for survival. Mark this day in your calendars as a potential turning point for Europe. >>

# age: the first of five big report (800-page) on longevity by academic and industry ventures

<< The longevity field is bustling but still fragmented, and the “silver tsunami” is coming. >>

<< That is the takeaway of The Science of Longevity, the behemoth first volume of a four-part series offering a bird’s-eye view of the longevity industry in 2017. The report, a joint production of the Biogerontology Research Foundation, Deep Knowledge Life Science, Aging Analytics Agency, and Longevity.International, synthesizes the growing array of academic and industry ventures related to aging, healthspan, and everything in between. >>

# gene: the generation of color pattern in ladybird beetle (H. axyridis aka harlequin ladybird).

<< Many ladybirds have attractive color patterns consisting of black and red. This prominent color pattern is thought to function as a warning that indicates to predators that they are very bitter and unpalatable. >>

AA << focused on the multicolored Asian ladybird beetle Harmonia axyridis (also known as the harlequin ladybird), which lives mainly in Siberia and East Asia, and shows >200 color patterns within a species. The team has identified a single gene that regulates such highly diverse ladybird color patterns. >>

# 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. >>
