Data from: Dissecting the contributions of plasticity and local adaptation to the phenology of a butterfly and its host plants
Phenology affects the abiotic and biotic conditions that an organism encounters and consequently its fitness. For populations of high latitude species, spring phenology often occurs earlier in warmer years and regions. Here we apply a novel approach to decompose spatiotemporal covariation between spring temperature and the phenology of two flowering plants, Cardamine pratensis and Alliara petiolata, and a Lepidopteran herbivore, Anthocharis cardamines, across the UK, into the contributions of plasticity and local adaptation. All three species overlap in the time-window over which mean temperatures best predict variation in phenology and we find little evidence that the position of time-windows varies latitudinally, as expected if they were initiated by day-length. The focal species show pronounced temperature-mediated phenological plasticity of similar magnitude. While we find no evidence for local adaptation in the flowering times of the plants, geographic variation in the phenology of the butterfly reveals countergradient local adaptation. Geographic variation in the butterfly's phenology appears to be more sensitive to variation in temperature than the flowering times of the host plants and we find no evidence that coevolution has generated geographic variation in adaptive phenological plasticity.

Mechanistic dissection of increased enzymatic rate in a phase-separated compartment
<p><span>Biomolecular condensates concentrate macromolecules into discrete cellular foci without an encapsulating membrane. Condensates are often presumed to increase enzymatic reaction rates through increased concentrations of enzymes and substrates (mass action), although this idea has not been widely tested and other mechanisms of modulation are possible. Here we describe a synthetic system where the SUMOylation enzyme cascade is recruited into engineered condensates generated by liquid-liquid phase separation of multidomain scaffolding proteins. SUMOylation rates can be increased up to 36-fold in these droplets compared to the surrounding bulk, depending on substrate K<sub>M</sub>. This dependency produces substantial specificity among different substrates. Analyses of reactions above and below the phase separation threshold lead to a quantitative model in which reactions in condensates are accelerated by mass action and by changes in substrate K<sub>M</sub>, likely due to scaffold-induced molecular organization. Thus, condensates can modulate reaction rates both by concentrating molecules and by physically organizing them.</span></p>
Data from: An uncommon cause of carotid artery dissection: Fabry disease.
<p>Internal cervical artery dissection represent a common etiology of stroke in the young, while the most common central nervous system manifestation of Fabry Disease (FD) is acute cerebral ischemia. Nevertheless, internal carotid artery disease has been scarcely associated with Fabry Disease. </p> <p>We describe the neuroimaging findings of an 49-year-old patient presenting with acute left middle cerebral artery occlusion due to an underlying internal carotid artery dissection. The patient was successfully treated with intravenous thrombolysis and mechanical thrombectomy. Further diagnostic work-up revealed bilateral cornea verticillata and large-fiber polyneuropathy with impaired cold and warm perception. Low a-galactosidase levels and molecular genetic testing established the diagnosis of Fabry Disease, while the patient was started on oral chaperone therapy with migalastat. </p> <p>The present case highlights that Fabry Disease may occasionally manifest with internal carotid artery dissection and that FD should be included in the diagnostic work-up of spontaneous internal carotid artery dissection. <br> </p>
