Potential treatment for chronic kidney disease in dogs revealed

A new study suggests that paricalcitol may help manage chronic kidney disease (CKD) in dogs by reducing renal secondary hyperparathyroidism and proteinuria. The treatment showed promise in stabilizing proteinuria, but raised questions about potential long-term effects on CKD progression.

Discrimination in the application process? It depends

A study by social psychologist Melanie Steffens found that high qualifications can overcome negative stereotypes, but even small amounts of additional information can activate biases. Researchers also discovered that certain groups, such as Turkish women, are more likely to be excluded from job opportunities due to stereotypes.

The emerging role of flavonoids in the treatment of type 2 diabetes mellitus: regulating the enteroendocrine system

Research suggests flavonoids improve insulin sensitivity, enhance β-cell function, modulate the gut microbiota, inhibit gluconeogenesis, and regulate enteroendocrine hormones in type 2 diabetes management. Flavonoid-specific effects on GLP-1, GIP, PYY, and CCK secretion contribute to improved glycemic control.

Prevalence and severity of astigmatism in children after COVID-19

A new study published in JAMA Ophthalmology found that lifestyle changes after COVID-19 were associated with an increase in the prevalence and severity of child astigmatisms. The potential impact of higher degrees of astigmatism may warrant dedicated efforts to elucidate the relationship between environmental and/or lifestyle factors.

How could artificial intelligence be used globally to increase fairness in the distribution of public social services?

The AI FORA project analyzed how AI-based social assessment varies across nine countries and four continents, highlighting the need for flexible, dynamic, and adaptive systems that reflect social stakeholders' perspectives. The research aims to improve AI in addressing fairness and discrimination issues in public social services.

Majority of carbon sequestered on land is locked in nonliving carbon reservoirs

A new study finds that the majority of carbon dioxide absorbed by ecosystems is stored in dead plant material, soils, and sediments. This discovery suggests that terrestrial carbon stocks are more resilient and stable than previously thought, with most carbon sequestered over the last three decades stored in nonliving organic matter.

Could the layout of trees impact human health?

Researchers found that large, contiguous areas of well-networked tree canopies lower mortality risk in densely developed cities. Compact, geometrically simple areas of tree canopy also show a positive effect on health. The study suggests that connecting isolated green spaces and promoting biodiversity can support human health.

Overcoming stacking constraints in hexagonal boron nitride via metal-organic chemical vapor deposition

Scientists at POSTECH and University of Montpellier successfully synthesized wafer-scale hexagonal boron nitride (hBN) with an AA-stacking configuration using metal-organic chemical vapor deposition (MOCVD). This achievement introduces a novel route for precise stacking control in van der Waals materials.

Study finds foreign aid sanctions set back decades of progress on maternal and child mortality

A recent Stanford University study found that foreign aid sanctions can negate up to 64% of progress against maternal mortality, with similar impacts on infant and child mortality. The researchers estimate that sanctions lasting five years or more can lead to significant increases in death rates among mothers, children, and infants.

Mountain uplift and dynamic topography shapes biodiversity over deep time

Research reveals that mountain uplift and dynamic topography significantly shape biodiversity over geological timescales. By simulating millions of years of tectonic uplift, scientists found a direct link between species richness and the magnitude and pace of mountain building, with topographic relief stabilizing species equilibrium.

Self-assembled vesicles containing podophyllotoxin covalently modified with polyoxometalates for antitumor therapy

The team successfully prepared an amphiphilic drug molecule PPT-POM-PPT, which exhibits excellent anticancer activity against various tumor cells while showing low toxicity to normal cells. The self-assembling vesicles deliver the drug without additional carrier materials, improving stability and biocompatibility.

Anxiety disorders in children can be screened through school health care

A new study from the University of Turku screened school-age children for anxiety and found that a Master Your Worries programme reduced symptoms of generalised anxiety, social anxiety, and separation anxiety. The study also showed that lighter digital study materials can reduce anxiety symptoms in children.

The fine control of cell mechanics

Researchers discovered that gamma-actin increases the rigidity of cell membranes while beta-actin filaments are less stiff. This mechanism may contribute to hearing loss by affecting the apical membrane's stiffness essential for auditory function.
