Metal-halide perovskites have been shown to be remarkable and promising optoelectronic materials. However, despite ongoing research from multiple perspectives, some fundamental questions regarding their optoelectronic properties remain controversial. One reason is the high-variance of data collected from, often unstable, polycrystalline thin films. Here we use ordered arrays of stable, single-crys

In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or

Citizen science is a powerful tool for connecting members of the public with research and for obtaining large amounts of data. However, it is far less commonly implemented in developing countries than in developed countries. We conducted a large-scale citizen-science program monitoring honey bee (Apis mellifera) colony losses in Argentina to examine how a national consortium composed of local coor

A circular economy maximizes the value of material resources and minimizes greenhouse gas emissions, resource use, waste and pollution. We will posit that circularity needs to be understood as a property of a system (e.g., the mobility system of a city), rather than a property of an individual product or service (e.g., a car or a car-sharing service). Hence, there is a need for more knowledge on h

Recent studies suggest that oncogenic processes (from precancerous lesions to metastatic cancers) are widespread in wild animal species, but their importance for ecosystem functioning is still underestimated by evolutionary biologists and animal ecologists. Similar to what has been observed in humans, environmental modifications that often place wild organisms into an evolutionary trap and/or expo

The volume of credit to Swedish households has grown twice as fast as incomes since the mid-1990s. This has resulted in both rising house prices and rising household debt. This column argues that these trends expose Sweden to important economic vulnerabilities. Curbing these vulnerabilities will require prompt action by the authorities.

Fredrik NG Andersson and Lars Jonung argue that the current push for fiscal activism is short-sighted. Instead, the Swedish case from the last 25 years shows that stable public finances combined with supply-side policies is the recipe for economic stability and growth.

Gastric bypass surgery has benefi cial effects on obesity-induced metabolic disturbances, but the underlying mechanisms remain unclear. As Wnt genes are both positively and negatively correlated with obesity-induced adipose tissue infl ammation and insulin resistance, our main aim is to reveal a potential role for Wnt signaling in the reversal of these metabolic consequences after gastric bypass s

Diagnostic measurement of electric skin conductivity (ESC) called the Ryodoraku system was introduced in mid 1950s by Nakatani. As has been shown by Ziobro et al. in case of infantile cerebral palsy, changes of ESC may provide a valuable electrophysiological parameter for monitoring a therapy. In this study ESC was measured in asthmatic children treated with a bioelectronic unit VEGA-SELECT. Analy

In the setting of transplantation, T cells are deliberately depleted to prevent allograft rejection. However, this IL-7 activates the accelerated proliferation of effector memory T cells, which are the predominant mediators of graft rejection. Multipotent adult progenitor cells (MAPC) have been previously shown to modulate the response of T cells to IL-7, in vitro but not in vivo. Here, for the fi

Infection of orthopedic implants is a growing clinical challenge to manage due to the proliferation of drug-resistant bacterial strains. In this study, we aimed to investigate whether the treatment of implants with ceragenin-90 (CSA-90), a synthetic compound based on endogenous antibacterial peptides, could prevent infection in a novel rat model of periprosthetic joint infection (PJI) challenged w

We present how the microenvironment can directly improve biocatalytic selectivity of immobilized β-glucosidase. β-Glucosidase from Thermotoga neapolitana was immobilized on a variety of functionalized off-stoichiometric thiol-ene (OSTE) particles, where highest activities were observed for thiol and imidazole functional particles. Compared to the soluble enzyme, the selectivity (rs/rh) between tra

The effect of Fe3O4 nanoparticles and carbon nanotubes (CNTs) on the viscosity of a nanofluid is experimentally investigated from 278 to 313 K by changing the nanoparticle volume fraction. These nanoparticles were put into distilled water with various surfactants, i.e., Colace (docusate sodium), trisodium citrate dihydrate (TSC), polyvinyl pyrrolidone, cetyl trimethylammonium bromide, tetramethyla

DNA analysis has seen an incredible development in terms of instrumentation, assays and applications over the last years. Massively parallel sequencing (MPS) and digital PCR are now broadly applied in research and diagnostics, and quantitative PCR is used for more and more practises. All these techniques are based on in vitro DNA polymerization and fluorescence measurements. A major limitation for

Renal Fanconi syndrome developed rapidly in a 3-year-old Moroccan girl with established lysinuric protein intolerance. She was hospitalized because of lowered consciousness, uncoordinated movements and hepatosplenomegaly after a febrile period. Laboratory investigations revealed plasma ammonia 270 micromol/L (normal

Background: The main purpose for measuring urinary free sialic acid (FSA) is to diagnose sialic acid (SA) storage diseases. Elevated amounts of conjugated sialic acid (CSA) are observed in several diseases indicating the need to quantify CSA as well. A LC-MS/MS method for quantification of FSA and total sialic acid (TSA) in urine is developed and validated. Methods: FSA is analyzed directly after

Deposition, annealing, and integration of ferroelectric Hf x Zr 1 - x O 2 (HZO) thin films on the high-mobility semiconductor InAs using atomic layer deposition are investigated. Electrical characterization reveals that the HZO films on InAs exhibit an enhanced remanent polarization compared to films formed on a reference TiN substrate, exceeding 20 μ C / cm 2 even down to an annealing temperature
