Data from: Low fasting serum insulin and dementia in nondiabetic women followed for 34 years
Objective: A previous study reported a U-shaped association between fasting insulin and dementia in a 5-year follow-up of a male cohort, which was now re-investigated in a representative population of women followed over 34 years, and taking into account the incidence of diabetes. Methods: Fasting values for insulin and glucose were obtained from serum samples in 1212 non-diabetic women aged 38-60 at the 1968 baseline. Risk of dementia was assessed by Cox proportional hazard regression adjusting for insulin, glucose, and other covariates, and, in a second model, after censoring for incident cases of diabetes. Incident diabetes was considered as a third endpoint, for comparison with dementia. Results: Over 34 years, we observed 142 incident cases of dementia. The low tertile of insulin displayed excess risk for dementia, hazard ratio (HR) = 2.34, 95% confidence interval = (1.52, 3.58), compared to the medium tertile, but the high tertile of insulin did not, HR = 1.28 (0.81, 2.03). These associations were also seen for dementia without diabetes comorbidity. In contrast, high but not low insulin predicted incident diabetes (115 cases), HR = 1.70 (1.08, 2.68) and HR = 0.76 (0.43, 1.37), respectively. Conclusions: Our results revealed a non-linear association between fasting serum insulin and dementia in a female population, with high risk at low insulin values that was not attributable to preclinical dementia or impaired insulin secretion. This condition suggests a new pathway to dementia, which differs from the metabolic pathway involving diabetes.
Data from: Successful despite poor flight performance: range expansion is associated with enhanced exploratory behaviour and fast development
Anthropogenic interference forces species to respond to changing environmental conditions. One possible response is dispersal and concomitant range shifts, allowing individuals to escape unfavourable conditions or to track the shifting climate niche. Range expansions depend on both dispersal capacity and the ability to establish populations beyond the former range. We here compare well-established core populations with recently established edge populations in the currently northward expanding butterfly Lycaena tityrus. Edge populations were characterized by shorter development times and smaller size, a higher sensitivity to high temperature, and an enhanced exploratory behaviour. The differences between core and edge populations found suggest adaptation to local climates and an enhanced dispersal ability in edge populations. In particular, enhanced exploratory behaviour may be advantageous in all steps of the dispersal process and may have facilitated the current range expansion. This study describes differences associated with a current range expansion, knowledge which might be useful for a better understanding of species responses to environmental change. We further report on variation between males and females in morphology and flight behaviour, with males showing a longer flight endurance and more pronounced exploratory behaviour than females.
Data from: Extremely fast feeding strikes are powered by elastic recoil in a seahorse relative, the snipefish, Macroramphosus scolopax
Among over 30,000 species of ray-finned fishes, seahorses and pipefishes have a unique feeding mechanism whereby the elastic recoil of tendons allows them to rotate their long snouts extremely rapidly in order to capture small elusive prey. To understand the evolutionary origins of this feeding mechanism, its phylogenetic distribution among closely related lineages must be assessed. We present evidence for elastic recoil powered feeding in the snipefish (Macroramphosus scolopax) from kinematics, dynamics, and morphology. High-speed videos of strikes show they achieve extremely fast head and hyoid rotational velocities, resulting in rapid prey capture in as short at 2 ms. The maximum instantaneous muscle-mass-specific power requirement for head rotation in snipefish was above the known vertebrate maximum, which is evidence that strikes are not the result of direct muscle power. Finally, we show that the over-center conformation of the four-bar linkage mechanism coupling head elevation to hyoid rotation in snipefish can function as a torque reversal latch, preventing the head from rotating and providing the opportunity for elastic energy storage. The presence of elastic recoil feeding in snipefish means that this high-performance mechanism is not restricted to the Syngnathidae (seahorses and pipefish) and may have evolved in parallel.
Data from: Superfetation reduces the negative effects of pregnancy on the fast-start escape performance in live-bearing fish
<p>Superfetation, the ability to simultaneously carry multiple litters of different developmental stages <i>in utero</i>, is a reproductive strategy that evolved repeatedly in viviparous animal lineages. The evolution of superfetation is hypothesized to reduce the reproductive burden and, consequently, improve the locomotor performance of the female during pregnancy. Here, we apply new computer-vision based techniques to study changes in body shape and three-dimensional fast-start escape performance during pregnancy in three livebearing fishes (family Poeciliidae) that exhibit different levels of superfetation. We found that superfetation correlates with a reduced abdominal distension and a more slender female body shape just before parturition. We further found that body slenderness positively correlates with maximal speeds, curvature amplitude and curvature rate, implying that superfetation improves the fast-start escape performance. Collectively, our study suggests that superfetation may have evolved in performance-demanding (e.g. high flow or high predation) environments to reduce the locomotor cost of pregnancy.</p>

Fast grip force adaptation to friction relies on localized fingerpad strains
<p>Humans can quickly adjust their grip force to a change in friction at the object-skin interface during dexterous manipulation in a precision grip. To perform this adjustment, they rely on the feedback of the mechanoreceptive afferents innervating the fingertip skin. Because these tactile afferents encode information related to skin deformation, the nature of the feedback signaling a change in friction must somehow originate from a difference in the way the skin deforms when manipulating objects of different frictions. To better characterize the origin of the underlying sensory events, we asked human participants to perform a grip-lifting task with a manipulandum equipped with an optical imaging system. This system enabled to monitor fingertip skin strains through transparent plates of glass that had different levels of friction. We observed that, following an unexpected change in friction, participants adapted their grip force within 370ms after contact with the surface. By comparing the deformation patterns when unexpectedly switching from a high to a low friction condition, we found a significant increase in skin deformation inside the contact area arising over 100ms before the motor response, during the loading phase, suggesting that local and partial deformation patterns prior to lift-off are used in the nervous system to adjust the grip force as a function of the frictional condition.</p>
