Small animals that winter at northern latitudes need to maximize energy intake and minimize energy loss. Many passerine birds use night-time hypothermia to conserve energy. A potential cost of night-time hypothermia with much theoretical (but little empirical) support is increased risk of night-time predation, due to reduced vigilance and lower escape speed in hypothermic birds. This idea has neve

Patient counseling on physical fitness remains underutilized in primary care, despite its clinical and cost effectiveness. Most counseling interventions have focused on aerobic activity and neglected another vital component of physical fitness, muscle strengthening, which has recently been shown to be independently protective against cardiometabolic diseases and premature mortality.

Lytic polysaccharide monooxygenases (LPMOs) are copper-containing metalloenzymes that can cleave the glycosidic link in polysaccharides. This could become crucial for production of energy-efficient biofuels from recalcitrant polysaccharides. Although LPMOs are considered oxygenases, recent investigations have shown that H2O2 can also act as a co-substrate for LPMOs. Intriguingly, LPMOs generate H2

Cities are key actors in reducing both the causes of climate change (mitigation) and its impact (adaptation), and many have developed separate mitigation and adaptation strategies and measures. However, in order to maximize outcomes, both scholars and practitioners are increasingly calling for more integrated and synergetic approaches. Unfortunately, related research remains scarce and fragmented,

Trädgårdsboken om JORD ger svar på det mesta du behöver veta om jord i den egna trädgården. Vad är jord? Hur påverkar den oss och vår odling? Hur kan man förbättra, gödsla och underhålla olika sorters jord? Vilket förhållande har våra mest älskade växter till jorden? Jorden är nyckeln till allt. Sandlätt, torr och ljus eller mörk och en aning trött på hösten? Kunskap och omsorg om jorden är grun

Våra jordar är basen för en hållbar matproduktion. Vi har tagit jorden och jordarna för självklara men jordens hälsa är en garanti för framtiden. Jorden vi trampar på är av största vikt för allt levande på land. Med tanke på den alarmerande hastighet med vilken världens jordar håller på att förstöras är det viktigt att fästa uppmärksamheten på jord som en värdefull resurs som måste bevaras och utn

To combat the problem of encryption key recovery from main memory using cold boot-attacks, various solutions has been suggested, but most of these have been implemented on the x86 architecture, which is not prevalent in the smartphone market, where instead ARM dominates. One existing solution does exist for the ARM architecture but it is limited to key sizes of 128 bits due to not being able to ut

‘Creativity’ has become a buzzword throughout educational debates and strategy papers worldwide. By linking creativity to innovative capacity, it is commonly associated with the challenges and opportunities as generated by the knowledge economy. While the importance of creative approaches to learning is generally accepted, it has proven much more difficult to define and potentially assess skills a

We analyze how the content of ecosystem service research has evolved since the early 1990s. Conducting a computational bibliometric content analysis we process a corpus of 14,118 peer-reviewed scientific article abstracts on ecosystem services (ES) from Web of Science records. To provide a comprehensive content analysis of ES research literature, we employ a latent Dirichlet allocation algorithm.

Decomposition of soil organic matter (SOM) contributes significantly to the global carbon (C) cycle and climate feedbacks. SOM decomposition depends on soil microbial activities, and these activities are driven by the availability of C and other nutrients. Plant root exudates are known to alter decomposition of SOM, a phenomenon referred to as rhizosphere priming effects (RPE).

Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperature change has been compiled.

Objective To describe the frequency of myocardial infarction (MI) prior to the diagnosis of systemic lupus erythematosus (SLE) and within the first 2 years of follow-up. Methods The systemic lupus international collaborating clinics (SLICC) atherosclerosis inception cohort enters patients within 15 months of SLE diagnosis. MIs were reported and attributed on a specialised vascular event form. MIs

BACKGROUND: Genetic association studies have reported single-nucleotide polymorphisms (SNPs) at chromosome 19q13.3 to be associated with prostate cancer (PCa) risk. Recently, the rs61752561 SNP (Asp84Asn substitution) in exon 3 of the kallikrein-related peptidase 3 (KLK3) gene encoding prostate-specific antigen (PSA) was reported to be strongly associated with PCa risk (P 2.3 108). However, the bi

We explored determinants of depressive mood in adults with coronary artery disease and obstructive sleep apnea and response to positive airway pressure treatment in sleepy and non-sleepy phenotypes. In this secondary analysis of the RICCADSA trial conducted in Sweden, 493 cardiac patients with obstructive sleep apnea (n = 386) or no obstructive sleep apnea (n = 107) with complete Epworth Sleepines

Terrestrial biogeochemical feedbacks to the climate are strongly modulated by the temperature response of soil microorganisms. Tropical forests, in particular, exert a major influence on global climate because they are the most productive terrestrial ecosystem. We used an elevation gradient across tropical forest in the Andes (a gradient of 20°C mean annual temperature, MAT), to test whether soil
