Unlocking precise composition analysis of nanomedicines

Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, researchers developed a new analytical method combining an asymmetric flow field-flow fractionation system and mass spectrometry to separately quantify these forms. This technique allows for better quality control and safety

Portable sensor enables community lead detection in tap water

Lead contamination in municipal water sources is a consistent threat to public health. Ingesting even tiny amounts of lead can harm the human brain and nervous system — especially in young children. To empower people to detect lead contamination in their own homes, a team of researchers developed an accessible, handheld water-testing system called the

Traditional diagnostic decision support systems outperform generative AI for diagnosing disease

Researchers compared their long-standing diagnostic decision support systems AI tool, DXplain, with modern large language models like ChatGPT and Gemini, finding DXplain performed slightly better. They say their findings suggest that combining DXplain with LLMs could enhance clinical diagnosis and improve both technologies.

Thousands of sensors reveal 3D structure of earthquake-triggered sound waves

Earthquakes create ripple effects in Earth’s upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan’s extensive network of Global Navigation Satellite System (GNSS) receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake. Their results show sound wave disturbance

An iron oxide ‘oxygen sponge’ for efficient thermochemical hydrogen production

As the world shifts toward sustainable energy sources, ‘green hydrogen’ – hydrogen produced without emitting carbon – has emerged as a leading candidate for clean power. Scientists have now developed a new iron-based catalyst that more than doubles the conversion efficiency of thermochemical green hydrogen production.
