Medical Xpress / Study suggests testosterone therapy in men may be overprescribed, inconsistent with clinical guidelines
Only a small number of men who were prescribed testosterone therapy received appropriate, guideline-concordant diagnostic testing, according to a study presented at ENDO 2026, the Endocrine Society's annual meeting in Chicago, ...
Tech Xplore / Battery-free artificial photosynthesis keeps solar fuel production stable under shifting sunlight
Researchers at Osaka Metropolitan University have developed an artificial photosynthesis system capable of producing solar fuels more stably by integrating a self-regulating chemical component directly into the electrolyzer ...
Phys.org / Carbon dioxide unlocks safer oxidation chemistry under room-temperature conditions
Oxidation reactions are indispensable to the chemical industry, but from a process safety perspective, they are among the most challenging transformations. A research team at the University of Bayreuth, working in collaboration ...
Medical Xpress / Engineers find a way to deliver drugs directly to the esophagus
There are few treatment options available for people with disorders of the esophagus. Delivering drugs directly to this part of the body is difficult, so patients are usually treated with systemic drugs, which can have unwanted ...
Medical Xpress / Retinal cell subgroups may unlock more effective transplants for blindness
A new understanding of retinal cell development may help pave the way for future retina transplants, which could restore sight to people whose conditions currently have no effective treatments, according to researchers at ...
Phys.org / Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago
The discovery of fire was a major milestone in human evolution, giving our ancestors a way to stay warm, ward off predators, and eventually start cooking food. But exactly when this first happened is still intensely debated, ...
Phys.org / Massive Kamchatka earthquake has extended rupture that overlaps 1952 event, researchers find
Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8 Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers (311 miles) from its epicenter.
Phys.org / Bidirectional manipulation of gate-free quantum electronic states via semiconductor interface engineering
A recent study published in Nature Communications demonstrates precise control over electron spatial arrangement in two directions simultaneously—without any applied voltage—through interface engineering between semimetal ...
Phys.org / DNA tracking links raccoons to riverborne bacteria with possible human spillover
The emerging infectious bacterium Escherichia albertii has caused outbreaks of severe food poisoning and hospitalized people through contaminated water and foods, such as salad ingredients. Now, a new study from Osaka Metropolitan ...
Phys.org / AI tracks missing hydrogen atoms in crystals with 97% success rate
Artificial intelligence is often used to generate images. In research, specialized AI models are used for scientific applications—for example, to predict the positions of atoms in materials. The MatterGen model developed ...
Phys.org / Cosmic dawn fuel discovery unlocks early galaxy growth secrets
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the ...
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
