Medical Xpress / Q&A: Lowering radiation dose in chest X-ray imaging yields same accuracy, researcher finds
Digital tomosynthesis (DTS) is an X-ray technique that provides sectional images with better lesion visibility than conventional chest radiography (CXR), while using far less radiation than CT. Masoud Jadidi will defend his ...
Phys.org / JWST study suggests a handful of 'leaky' galaxies reionized the early universe
A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
Medical Xpress / Reinitiating obesity meds after bariatric surgery tied to greater one-year weight loss in youths
Restarting obesity medications, including glucagon-like peptide-1 (GLP-1) receptor agonists, soon after sleeve gastrectomy (SG) is associated with greater one-year weight loss than surgery alone in adolescents, according ...
Phys.org / An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core
Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core ...
Phys.org / How dogs evolved differently across the globe to match human traits
We call them "man's best friend," and the evidence supports it. Dogs have been found buried alongside humans in graves dating back 14,000 years. They appear in ancient art from every continent, and they feature in the mythology, ...
Medical Xpress / Traditional prostate cancer risk factors do not predict hormone therapy benefit, study finds
A new study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that while traditional pathological features used to classify aggressive prostate cancer—such as high-grade disease, cancer extending ...
Medical Xpress / Solving a mysterious inflammatory fever opens the book on a much bigger story
Three research teams working independently around the world have landed on the same discovery: A single molecular "handshake" inside our cells controls a family of inflammatory diseases, including one of the most common inherited ...
Phys.org / Corn-stalk sugars feed new bacterial strain designed to make useful chemicals
Engineers have developed a strain of a common bacterial species that can feed exclusively on the three major sugars present in corn stalks. While the new multiple-sugar-consuming strain of the bacterium Pseudomonas putida ...
Tech Xplore / Why do we labor when reading some words but not others? AI offers a partial answer
Why do we breeze through some sentences in a book or article but have to reread others to comprehend their meaning? A team of linguists and data scientists has found a partial answer in AI—some of this processing parallels ...
Phys.org / Economic losses from natural disasters fall to $100 bn in first half of 2026: Swiss Re
Economic losses from natural catastrophes worldwide are estimated to have reached $100 billion in the first half of this year, reinsurance group Swiss Re said Tuesday, a sharp decline from the same period last year.
Tech Xplore / Electronic skin enables tunable touch and proximity sensing for robots and prosthetics
Recent advances in miniaturized and portable electronics, particularly wearable and flexible devices, have increased the demand for self-powered sensing technologies. Among these, triboelectric nanogenerators (TENGs) have ...
Medical Xpress / Wearable tech for babies shows that night awakenings more common than parents believe
Almost half of Finnish parents feel that their infants' sleep is abnormal. However, measuring sleep disturbances is complicated. In her doctoral thesis, University of Helsinki researcher Sofie de Sena investigated infant ...
