Medical Xpress / Breathalyzer can 'sniff out' when your body starts burning fat
Researchers have developed a breath detector with a chemical sensor that sniffs out when your body is burning fat through a single exhale. Reporting in Device, the handheld, smartphone-assisted device measures acetone—a ...
Phys.org / First 3D nanoscale maps of human airway epithelium reveal hidden architecture of lung defense cells
Researchers at Queen Mary University of London and University of Cambridge in collaboration with colleagues at HHMI Janelia and NIH, have created some of the most detailed three-dimensional maps ever generated of human airway ...
Medical Xpress / FDA-issued sodium targets yield no apparent impact
In 2021, the U.S. Food and Drug Administration (FDA) issued Phase I voluntary sodium reduction targets to encourage manufacturers to lower the amount of sodium in packaged food products by 2024. The targets appear to have ...
Phys.org / Programmable platform enables on-demand design of plant immune receptors against crop pathogens
Crop production faces threats from plant pathogens. Traditional disease-resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to particular pathogens. However, rapidly evolving ...
Medical Xpress / Three genetic modifiers may alter inherited Alzheimer's onset and progression
Autosomal dominant Alzheimer's disease (ADAD) is a genetically inherited form of Alzheimer's disease that accounts for only about 1% of Alzheimer's disease cases. However, because individuals with the gene mutations are extremely ...
Phys.org / Geophysics brings clarity to the potential of natural hydrogen
Natural hydrogen is considered a potential low-carbon energy source. But how much is generated underground—and how quickly? An international research team led by the LIAG Institute for Applied Geophysics in Hannover has published ...
Phys.org / Hawaiian stilt reclassified from endangered to threatened after 50 years of conservation efforts
The U.S. Fish and Wildlife Service announced the reclassification of the Aʻeo, or Hawaiian stilt (Himantopus mexicanus knudseni), from endangered to threatened under the Endangered Species Act, a rare and hopeful milestone ...
Phys.org / Ceramic vessels reveal how social inequalities were also cooked into 19th-century Brazil
Fish, shellfish, maize, manioc, rice and even chicken eggs. Molecular residues preserved in more than 180 ceramic vessels from southern Brazil have made it possible to reconstruct what different communities were cooking more ...

Phys.org / Children and monkeys share common understanding of geometry
With their ability to use tools, remember faces and even learn how to communicate with humans through sign language, nonhuman primates are considered to be among the smartest creatures on Earth. However, some concepts—geometry, ...
Phys.org / Quantum sensing microscope illuminates transistor design
Artificial intelligence faces an energy crisis stemming from a physical traffic jam inside modern computer chips. Processors must continually shuffle data, such as the billions of parameters in complex models, between separate ...
Medical Xpress / Prebiotic sodas typically contain as much sugar as fiber, raising questions about gut-health claims
Prebiotic sodas have become more popular in recent years, with a wave of new products promising gut health benefits and low-calorie enjoyment. According to a new analysis, however, many of these beverages contain relatively ...
