Mud pies for some, barriers for others: National guidelines needed to make nature play work for every child

A new study reveals a gap in how nature playspaces are designed and delivered across Australia, with no clear evidence-based guidelines to support children of all ages and capabilities. Researchers call for national, research-backed recommendations to ensure consistency and quality across the country.

Research collaboration charts global four-stage evolution of inflammatory bowel disease

Researchers from UCalgary and Chinese University of Hong Kong found that IBD progresses through four predictable epidemiological stages as it spreads globally. The study forecasts a major rise in IBD prevalence in Canada by 2045, with countries in North America, Europe, and Oceania reaching Stage 3 (compounding prevalence). Developing ...

From the front garden to the continent: Why biodiversity does not increase evenly from small to large

Researchers developed a universal theory to explain species distribution patterns, estimating species numbers at key transition points between phases. The three-phase pattern of Species-Area Relationships shows rapid increase in local areas, slowing down in regional areas, and accelerating on continental scales.

Stronger and safer: New design strategy for aluminium combines strength with hydrogen embrittlement resistance

Researchers have developed a new alloy design strategy that combines exceptional strength with superior resistance to hydrogen embrittlement. The approach enables dual nanoprecipitates to trap hydrogen and enhance strength, resulting in a 40% increase in strength and a five-fold improvement in hydrogen embrittlement resistance.

Restoring oil wells back to nature with moss

Researchers from the University of Waterloo have developed a method to restore tens of thousands of oil and gas exploration sites in western Canada using native moss. The technique involves transplanting moss onto decommissioned well pads, effectively recreating peatlands and supporting ecosystem development.

Road traffic accidents leading cause of pet cat deaths in the UK, Bristol Cats study finds

New research by the University of Bristol and Cats Protection reveals that road traffic accidents are the leading cause of death in UK pet cats under 8 years old. The study found that younger cats are at higher risk of death due to RTAs, while older cats are more likely to die from disease-related causes.

Existing treatments may help fight symptoms of severe form of muscular dystrophy, new research suggests

Researchers at Hospital for Special Surgery found that mesenchymal stromal cells produce cytokines stimulating resident macrophages to proliferate and accumulate, contributing to chronic inflammation. Existing therapies may help control muscle inflammation by suppressing macrophage infiltration and FAPs' CSF-1 production.

So, our city’s shrinking—Now what?

A study analyzed per capita municipal expenditures and their correlation with population changes in small and medium-sized cities in Japan. The results revealed that prioritizing child welfare expenditures is a key strategy to sustain populations, while city planning expenditures on street maintenance and construction were also effective.

Too few ward nurses linked to longer hospital stay, readmission, and risk of death

A long-term study published in BMJ Quality & Safety found that employing too few permanent nurses on hospital wards is linked to longer inpatient stays, readmissions, patient deaths, and ultimately costs more. Redressing the balance saves around £5000 for each year of healthy life gained, but not if temporary agency staff are used.

Palatable versus poisonous: Eavesdropping bats must learn to identify which prey is safe to eat

A study by scientists at the Smithsonian Tropical Research Institute found that juvenile fringe-lipped bats do not initially differentiate between palatable and unpalatable frogs and toads, but learn to identify toxic species through experience. As they mature, adult bats respond more strongly to palatable prey.

Broader antibiotic use could change the course of cholera outbreaks, research suggests

Mathematical modeling research from University of Utah Health suggests that treating moderate cases with antibiotics could limit the spread of cholera and reduce the likelihood of antibiotic resistance. In areas where cholera spreads slowly, aggressive antibiotic use may even stop outbreaks entirely.

Giant croclike carnivore fossils found in the Caribbean

A research team discovered fossilized teeth and vertebrae in the Dominican Republic, confirming that large, terrestrial predators like sebecids once inhabited the Caribbean. This finding supports the GAARlandia hypothesis, suggesting temporary land bridges allowed animals to travel between South America and the Caribbean.

Majority of Americans experience some form of gun violence in person

A national study by Rutgers researchers found that nearly two-thirds of US adults have experienced some form of in-person gun violence, with Black and Hispanic adults more likely to be exposed. The study also revealed significant racial disparities in media-based exposure, with Black adults reporting the highest levels of exposure.

Pediatric investigation review discusses the challenges, innovations, and future directions in dengue vaccine development

The review highlights the limitations of existing dengue vaccines, such as CYD-TDV and TAK-003, and the urgent need for more effective vaccines to protect millions of people. The Butantan-DV vaccine has shown promise with its single-dose regimen, but its efficacy against DENV-3 and DENV-4 is still unclear.
