A QUT study observed and compared 3401 bicycle food delivery riders and private cyclists in Brisbane, finding that they generally don't take more risks on the roads. The study found that helmets were worn by 97.4% of riders, with delivery riders wearing them at a higher rate than private cyclists.
A recent study by Dr Joseph Michalski from HKU suggests that the number of ancient Martian lakes may have been significantly overestimated. The analysis of satellite data reveals evidence for smaller lakes on Mars, which could contain critical information about past climates.
A research team from Dalian Institute of Chemical Physics has revealed the existence of reactive gallium-hydride species on the surface of gallium oxide using solid-state nuclear magnetic resonance. The discovery provides comprehensive information on the structural configuration and formation mechanism of these special M-H species.
Researchers developed lanthanide-doped fluoride nanoparticles that exhibit superior photostability, low toxicity and convenient device processability. These particles also show promising applications in biomedicine and optical information encoding, enabling broadband detection in theory.
Researchers propose a new coupling strategy combining photocatalytic water oxidation and catalytic wet peroxide oxidation to efficiently remove organic pollutants from wastewater. The proposed strategy achieves higher total organic carbon removal rates compared to traditional methods.
A new day-case surgical procedure for diabetic foot ulcers has been shown to accelerate effective healing, reduce recurrence, and prevent amputations. The procedure, which involves adjusting the mechanics of the foot, was found to be effective in treating up to 19 patients with successful ulcer resolution in just 3-4 weeks.
A recent academic study found that Facebook's introduction at American colleges was associated with a significant worsening in mental health symptoms, particularly depression and anxiety. The study used a novel research method to establish causality between social media use and poor mental health.
Oregon State University will collaborate with partners on a five-year project to enhance soil health and reduce the carbon footprint of the Pacific Northwest potato industry. The project aims to identify climate-smart practices that increase soil organic matter, reduce greenhouse gas emissions and improve water holding capacity.
