Medical Xpress / Ultra-processed foods in preschool years associated with behavioral difficulties in childhood
A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioral and emotional development. Specifically, the team found that higher ultra-processed ...
Phys.org / Upconversion materials: A new frontier in solar water-splitting
Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts and photoelectrodes absorb only a limited portion of solar radiation, mainly ultraviolet and part ...
Phys.org / Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products ...
Medical Xpress / Foundation AI model uses MRI data to predict multiple brain disorders
Artificial intelligence (AI) systems are computational models that can learn to identify patterns in data, make accurate predictions or generate content (e.g., texts, images, videos or sound recordings). These models can ...
Medical Xpress / Rethinking how we measure recovery from substance use
Nearly 50 million people in the United States struggle with substance use disorders, and nearly three in four use more than one substance. People with polysubstance use disorders are more likely than single drug users to ...
Phys.org / Möbius-inspired surface controls light in two directions
Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially ...
Phys.org / Tiny Purgatorius fossils in Denver Basin hint at early primate spread southward
New minuscule fossils of Purgatorius, the earliest-known relative of all primates—including humans—have been unearthed in a more southern region of North America than ever before, and the breakthrough is providing paleontologists ...
Phys.org / A fanged frog long thought to be one species is revealing itself to be several
When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other ...
Tech Xplore / 'ChatGPT for spreadsheets' helps solve difficult engineering challenges faster
Many engineering challenges come down to the same headache—too many knobs to turn and too few chances to test them. Whether tuning a power grid or designing a safer vehicle, each evaluation can be costly, and there may ...
Medical Xpress / No evidence ADHD is being over-diagnosed, say experts
Experts are warning that far from being over-diagnosed, people with ADHD are waiting too long for assessment, support, and treatment. In a paper published in the British Journal of Psychiatry, a group of experts say there ...
Tech Xplore / How hawks slip through tight gaps: A flight stability trick drones could copy
Birds have an ability to fly through obstacles by shifting their shape in flight, which is difficult to reproduce in uncrewed aerial vehicles, commonly known as UAVs or drones. A new study from researchers at the University ...
Medical Xpress / New study looks at hidden privacy concerns of menopause tech
New research by academics at Royal Holloway has revealed privacy and advice concerns surrounding technology aimed at helping women navigate menopause. The study, which surveyed 310 UK participants, is warning that sensitive ...
