In a controlled laboratory environment with students in Germany, we measured the productivity of participants in a real effort task, quantified their pro-environmental behavior, and recorded their individual Pace of Life. We find that individuals with a fast Pace of Life are significantly more productive. However, individuals with a fast Pace of Life behave less pro-environmentally if they are men and more pro-environmentally if they are women.},

  abstract  = {Looking times and gaze behavior indicate that infants can predict the goal state of an observed simple action event (e.g., object-directed grasping) already in the first year of life. The present paper mainly focuses on infants' predictive gaze-shifts toward the goal of an ongoing action. For this, infants need to generate a forward model of the to-be-obtained goal state and to disengage their gaze from the moving agent at a time when information about the action event is still incomplete. By about 6 months of age, infants show goal-predictive gaze-shifts, but mainly for familiar actions that they can perform themselves (e.g., grasping) and for familiar agents (e.g., a human hand). Therefore, some theoretical models have highlighted close relations between infants' ability for action-goal prediction and their motor development and/or emerging action experience. Recent research indicates that infants can also predict action goals of familiar simple actions performed by non-human agents (e.g., object-directed grasping by a mechanical claw) when these agents display agency cues, such as self-propelled movement, equifinality of goal approach, or production of a salient action effect. This paper provides a review on relevant findings and theoretical models, and proposes that the impacts of action experience and of agency cues can be explained from an action-event perspective. In particular, infants' goal-predictive gaze-shifts are seen as resulting from an interplay between bottom-up processing of perceptual information and top-down influences exerted by event schemata that store information about previously executed or observed actions.},

  abstract  = {Risk scores are used to identify high-risk individuals for type 2 diabetes (T2DM) who benefit from preventive measures. The DIfE-DEUTSCHER DIABETES-RISIKO-TEST (R) (DRT) is used to determine the absolute 5-year risk for T2DM. Since the calculation is based on non-clinical information, the test can be used independently of a doctor's visit. Data from prospective population-based long-term studies serve as the basis for the development of risk scores. As in the case of the DRT, the very good predictive quality of a score should be confirmed in independent populations. In addition to the use by doctors and for individual self-anamnesis, non-clinical risk scores can be used in the context of broader, population-based prevention concepts and information offers to reduce the risk of disease. Prevention services billable by health insurance companies should support the integration of health-promoting behavior into everyday life within the meaning of the German Prevention Act. Although obesity and diet are relevant lifestyle risk factors for T2DM, the proportion of preventive courses taken on this topic is only 3\% of the courses billed. Appropriate recommendations in medical examinations could promote more extensive use. The use of risk scores as the basis for systematic and targeted recommendations for behavioral prevention could also support this, as is already established in guidelines for cardiovascular prevention. The further development of implementation research is also important for the efficient use of risk scores.},

SDMDA allows a continuous variation in the microcrack density with tensile loading. Experimental uniaxial tensile response of beta-eucryptite glass and ceramics with controlled levels of microcracking is reported. It is demonstrated that SDMDA can well describe the extent of non-linearity in the experimental uniaxial tensile response of beta-eucryptite with varying levels of microcracking.

  abstract  = {Specialized glial subtypes provide support to developing and functioning neural networks. Astrocytes modulate information processing by neurotransmitter recycling and release of neuromodulatory substances, whereas ensheathing glial cells have not been associated with neuromodulatory functions yet. To decipher a possible role of ensheathing glia in neuronal information processing, we screened for glial genes required in the Drosophila central nervous system for normal locomotor behavior. Shopper encodes a mitochondrial sulfite oxidase that is specifically required in ensheathing glia to regulate head bending and peristalsis. shopper mutants show elevated sulfite levels affecting the glutamate homeostasis which then act on neuronal network function. Interestingly, human patients lacking the Shopper homolog SUOX develop neurological symptoms, including seizures. Given an enhanced expression of SUOX by oligodendrocytes, our findings might indicate that in both invertebrates and vertebrates more than one glial cell type may be involved in modulating neuronal activity.},

We used a total of 61 variables associated with organic compounds and trace element concentrations measured in muscle, liver, kidney and blubber gained from 24 sperm whales that stranded in the North Sea in January and February 2016. Combining contaminant and genetic data, there is evidence for at least two cohorts with different origin among these stranded sperm whales; one from the Canary Island region and one from the northern part of the Atlantic. While genetic data unravel relatedness and kinship, contamination data integrate over areas, where animals occured during their lifetime. Especially in long-lived animals with a large migratory potential, as sperm whales, contamination data may carry highly relevant information about aggregation through time and space.},

However, this is poorly understood in species with unusually high relatedness between individuals: clonal organisms. Although there has been some investigation into clonal invertebrates and yeast, nothing is known about kin selection in clonal vertebrates. We show that a clonal fish, the Amazon molly (Poecilia formosa), can distinguish between different clonal lineages, associating with genetically identical, sister clones, and use multiple sensory modalities. Also, they scale their aggressive behaviors according to the relatedness to other females: they are more aggressive to non-related clones. Our results demonstrate that even in species with very small genetic differences between individuals, kin recognition can be adaptive. Their discriminatory abilities and regulation of costly behaviors provides a powerful example of natural selection in species with limited genetic diversity.},

Increasing octopamine brain titers reduces responsiveness to light, while tyramine application enhances phototaxis. These findings suggest an involvement of octopamine signaling in honey bee phototaxis and possibly division of labor, which is hypothesized to be based on individual differences in sensory responsiveness.},

  abstract  = {Der ubiquit{\"a}r exprimierte, multifunktionale Glucosetransporter GLUT8 geh{\"o}rt zur Klasse III der Familie der passiven Glucosetransporter, die aus insgesamt 14 Proteinen besteht. Die f{\"u}nf Mitglieder der Klasse IIII unterscheiden sich strukturell leicht von den Mitgliedern der Klasse I und II (Joost und Thorens, 2001). GLUT8 besitzt ein N-terminales Dileucin-Motiv, das Teil eines [DE]XXXL[LI] Motivs ist, welches f{\"u}r die Sortierung des Transporters in sp{\"a}te Endosomen und Lysosomen verantwortlich ist (Augustin et al., 2005). Da bis heute kein Signal identifiziert wurde, das eine Translokation des Transporters zur Plasmamembran ausl{\"o}st, wird eine intrazellul{\"a}re Funktion von GLUT8 vermutet (Widmer et al., 2005). Im Rahmen der vorliegenden Arbeit wurde die intrazellul{\"a}re Funktion des Transporters in der Regulation der Glucosehom{\"o}ostase des K{\"o}rpers durch Analyse einer Slc2a8-knockout-Maus untersucht. Die homozygote Deletion des Transporters erbrachte lebensf{\"a}hige Nachkommen, die sich augenscheinlich nicht von ihren Wildtyp-Geschwistern unterschieden. Allerdings wurde bei Verpaarungen heterozygoter M{\"a}use eine verminderte Anzahl an Slc2a8-/--Nachkommen beobachtet, die signifikant von der erwarteten Mendel'schen Verteilung abwich. Da Slc2a8 die h{\"o}chste mRNA-Expression in den Testes aufwies und die {\"U}berpr{\"u}fung der Fertilit{\"a}t mittels verschiedener homozygoter Verpaarungen eine St{\"o}rung der weiblichen Fortpflanzungsf{\"a}higkeit ausschloss, wurden die Spermatozoen der Slc2a8-/--M{\"a}use eingehender untersucht. Als Ursache f{\"u}r die verringerte Anzahl von Slc2a8-/--Geburten wurde eine verminderte Prozentzahl motiler Slc2a8-/--Spermien ermittelt, die durch eine unzureichende mitochondriale Kondensation in den Spermien bedingt war. Diese Ver{\"a}nderung war mit einem reduzierten mitochondrialen Membranpotential assoziiert, was eine verminderte ATP-Produktion nach sich zog. Somit scheint GLUT8 in den Spermien an einem intrazellul{\"a}ren Transportprozess beteiligt zu sein, der einen Einfluss auf die oxidative Phosphorylierung der Mitochondrien aus{\"u}bt. Im Gehirn wurde Slc2a8 besonders stark im Hippocampus exprimiert, der in der Regulation von k{\"o}rperlicher Aktivit{\"a}t, Explorationsverhalten, Erinnerungs- und Lernprozessen sowie Angst- und Stressreaktionen eine Rolle spielt. Außerdem wurde GLUT8 im Hypothalamus nachgewiesen, der unter anderem an der Regulation der Nahrungsaufnahme beteiligt ist. Die Slc2a8-/--M{\"a}use zeigten im Vergleich zu ihren Slc2a8+/+-Geschwistern eine signifikant gesteigerte k{\"o}rperliche Aktivit{\"a}t, die zusammen mit der von Membrez et al. (2006) publizierten erh{\"o}hten Zellproliferation im Hippocampus auf eine N{\"a}hrstoffunterversorgung dieses Areals hindeutet. Die Nahrungsaufnahme war in Abwesenheit von GLUT8 nicht ver{\"a}ndert, was zusammen mit dem nur geringf{\"u}gig niedrigeren K{\"o}rpergewicht der Slc2a8-/--M{\"a}use eine Funktion von GLUT8 im Glucose-sensing der Glucose-sensitiven Neurone des Gehirns ausschließt. Das leicht reduzierte K{\"o}rpergewicht der Slc2a8-/--M{\"a}use ließ sich keinem bestimmten Organ- oder Gewebetyp zuordnen, sondern schien durch eine marginale Gewichtsreduktion aller untersuchten Gewebe bedingt zu sein. Zusammen mit den erniedrigten Blutglucosespiegeln und der anscheinend gesteigerten Lebenserwartung zeigten die Slc2a8-/--M{\"a}use Symptome einer leichten N{\"a}hrstoffunterversorgung. GLUT8 scheint daher am Transport von Zuckerderivaten, die w{\"a}hrend des lysosomalen/endosomalen Abbaus von Glykoproteinen anfallen, beteiligt zu sein. Die so wiederaufbereiteten Zucker dienen dem K{\"o}rper offenbar als zus{\"a}tzliche Energiequelle.},
