As phylogenetically basal metazoans, sponges (phylum Porifera) provide crucial insights into the origins of animal biomineralization and early body plan innovation. However, articulated sponge fossils remain exceptionally rare in Ediacaran–Cambrian transition strata, with most records limited to isolated spicules or ambiguous biomineralized structures. This study reports siliceous and phosphatical
BACKGROUND: The occurrence of migratory takeoff behavior is the essential first step for long-distance migration of insects. However, its characteristics, frequency of occurrence, and the identity of environmental and physiological factors influencing this process remain largely unknown. RESULTS: We investigate the global pest fall armyworm (FAW, Spodoptera frugiperda) as an exemplar species to in
Accurate evapotranspiration (ET) estimation is vital for hydrological modeling, yet remotely sensed ET (RS-ET) products are often limited by algorithmic uncertainties and sensor biases. To mitigate error propagation and better capture spatial patterns, this study introduces the Composite Efficiency of Absolute ET and Spatial Autocorrelation (CEASA) —a dual-constraint framework that integrates abso
Accurate reservoir dynamics, particularly water storage and inflow, are crucial for release decisions and operation rule assessments. However, the lack of sufficient monitoring data has hindered the accurate representation of reservoir behavior in hydrological models. While the increasing availability of satellite imagery provides unprecedented opportunities for dynamic reservoir monitoring, its p
Urban meteorology, the study of atmospheric phenomena in urban areas, is vital for understanding the dynamic interactions between rapid urbanization and environmental changes. Over the past two decades (2004–2024), urban heat islands (UHIs), extreme rainfall, pollution, and temperature anomalies have intensified, adversely affecting human health, infrastructure, and ecosystems worldwide. The prese
Environmental protection has become high in the policy agenda of East Asian countries by the end of the last century due to both internal and external stimuli. One of the main environmental issues is the management of solid waste. The concept of circular economy which encourages reduce, reuse, and recycling, i.e. 3Rs, together with the principle of Extended Producer Responsibility (EPR) has been p
Popular Abstract in Swedish Tibet och den tibetanska buddhismen har i väst ofta kommit att användas som synonymer. Tidigt kom landets otillgänglighet och stängda dörrar mot omvärlden att utöva en stark lockelse för resande och religiösa sökare. De kom i många fall att betrakta landet och dess folk som bevarare av en kunskap och vishet som gått den övriga världen förlorad. Föreställningen om den rThis dissertation in anthropology of religion focuses on images of Tibet, among Westerners as well as among Tibetans. Based on approximately one year of fieldwork in the former British Hill station, it also deals with the politics of the Central Tibetan Administration (CTA) and some of its political and social implications for the exiled Tibetan youth living in Dharamsala, India. The Western perc
AIMS: To investigate the disease causing event in patients with familial hypercholesterolaemia, carrying two mutations each, E256K in exon 6 and I402T in exon 9, of the gene encoding the low density lipoprotein (LDL) receptor. It was not known whether the mutations were positioned in cis or trans, or if they were each pathogenic separately or only when present together. METHODS: Polymerase chain r
Popular Abstract in Swedish För att celler ska kunna växa och dela sig behöver de många olika ämnen, till exempel vitaminer, mineraler och polyaminer. Polyaminer finns i alla celler och de krävs för att cellerna ska kunna dela eller specialisera sig. Cellerna kan både själva tillverka polyaminer och ta upp dem från omgivningen. I mänskliga celler finns framför allt de tre polyaminerna putrescin, sOur research group has previously shown that treatment with the polyamine biosynthesis inhibitors a-difluoromethylornithine (DFMO) or amidinoindan-1-one 2´-amidinohydrazone (CGP 48664) inhibited S phase progression before any other cell cycle phase was affected. This study was undertaken to further investigate the role of polyamines in the regulation of S phase progression and DNA synthesis. I hav
Efter att det blev känt att en kinesisk forskare hade genredigerat två embryon, blev genredigering ett mycket omtalat ämne runt om i världen. Händelsen ledde till stora diskussioner på olika nivåer och ledde till många rekommendationer kring de etiska avgränsningar som bör göras. Vetenskapen går ständigt framåt och därför är det av betydelse att göra en omfattande analys av hur rättsläget inom g
There are few studies on associations between respiratory health and allergens, fungal and bacterial compounds in schools in tropical countries. The aim was to study associations between respiratory symptoms in pupils and ethnicity, chemical microbial markers, allergens and fungal DNA in settled dust in schools in Malaysia. Totally 462 pupils (96%) from 8 randomly selected secondary schools in Joh
Entrepreneurs have difficulties in performing maintenance activities due to the increasing intensity of train services and failing infrastructure. Annually, the state loses billions of SEK due to delays caused by failures in infrastructure or maintenance not performed on time. The largest amounts of delays occur during winter time, when our infrastructure cannot cope with the climate as it is expo
We examined the occurrence of seasonal hypoxia (O-2 < 2 mg l(-1)) in the bottom waters of four river-dominated ocean margins (off the Changjiang, Mississippi, Pearl and Rhone Rivers) and compared the processes leading to the depletion of oxygen. Consumption of oxygen in bottom waters is linked to biological oxygen demand fueled by organic matter from primary production in the nutrient-rich river p

OBJECTIVE: The past few decades have been marked by a bold increase in national health spending across the globe. Rather successful health reforms in leading emerging markets such as BRICS reveal a reshaping of their medical care-related expenditures. There is a scarcity of evidence explaining differences in long-term medical spending patterns between top ranked G7 traditional welfare economies an
The anaerobic oxidation of methane (AOM) removes most of the biologically produced methane (CH 4 ) from marine ecosystems before it enters the atmosphere and thus mitigates greenhouse gas emissions. As compared to marine environ
Biogenic volatile organic compounds (BVOCs) play essential roles in tropospheric chemistry, on both regional and global scales. The emissions of large quantities of species-specific BVOC depend not only on environmental (temperature, T; photosynthetically active radiation, PAR), but also physiological parameters (i.e. net photosynthetic rate, Pn; transpiration rate, Tr; stomatal conductance, gs an
