A preliminary archaeological report on Quseir Al-Qadim documents evidence from the Red Sea port’s Roman and Islamic periods. Its chapters cover ceramics, glass, lamps, inscriptions, written records, textiles, animal and plant remains, marine life and historic mosques.
Researchers used a label-free light-based technique to monitor baculovirus infection in individual living Sf9 cells. Chemical signals from proteins and nucleic acids distinguished infected from uninfected cells, with accuracy as high as 0.94 in point measurements.
A study finds that mainstream parties’ adoption of far-right anti-Muslim rhetoric can weaken opposition to prejudice beyond attitudes toward Muslims. The effect appeared in Germany when the rhetoric came from mainstream parties, but not in comparable experiments in Denmark.
A study in southern Brazil found that Proteus mirabilis from retail vegetables shared close genetic relationships, resistance genes and virulence features with isolates from community-acquired urinary tract infections. The findings identify food-associated bacteria as a possible reservoir of lineages linked to human disease, although the study did not prove transmission.
A magnitude 8.8 earthquake off Kamchatka on July 29, 2025, sent a measurable tsunami across the Pacific to Mexico’s coast. Tide gauges recorded waves ranging from 0.13 to 0.76 meters, and tsunami energy lasted more than 24 hours at some stations.
An ultraviolet examination of a 22.2-centimeter ancient Egyptian ushabti found material evidence that its inscription was altered for a later owner. The object’s original five-line text was erased and partly replaced with a shorter inscription naming Jt.f.
Researchers created hydrogel composites that can be reshaped in water by changing the direction of polarized light. The cubes stretched to as much as twice their original side length, and the team made microscopic wells that could fully close.
Researchers reconstructed the lost bacteriophage PRR1 using its stored DNA sequence and produced working virus particles. Genetic, biological and microscopic tests found that the synthetic particles matched the traits historically reported for the original phage.
A study finds that extreme, persistent split jet stream patterns are associated with heatwaves occurring at several Northern Hemisphere locations at the same time. The longer the split pattern lasted, the more often these heatwaves occurred together.
A nationally representative survey of 1,894 Australian adolescents found that 14.9% had experienced online child sexual victimisation before age 18. Among reported cases, disclosure to an AI system was more common than disclosure to authorities, including police, teachers and online reporting platforms.
The European Union’s AI Act calls for providers to mark and detect outputs from general-purpose AI models. A new analysis finds that no current watermarking approach for large language models meets all four of the law’s stated standards: reliability, interoperability, effectiveness and robustness.
Continuous electrical measurements tracked cochlear implant electrode arrays as surgeons inserted them into the inner ear. In a study of 34 patients, the method agreed with the surgeon’s visual and hearing-based assessment 88.9% of the time.
A study of tropical cyclone records from 1980 to 2025 finds that hazards along East Asia have shifted toward higher latitudes. The change reflects altered storm paths and movement speeds rather than a long-term increase in the storms’ maximum strength.
In a German study, 23.6% of young people were classified as having at-risk social media use and 4.9% as having pathological use. Loneliness, rising feelings of exclusion and heavy social media use were associated with higher odds, while family cohesion, physical activity and better sleep were associated with lower odds.
Researchers report the first documented case of a humpback whale attending to a stillborn calf after its death. The female stayed close, repeatedly interacted with the calf and did not try to lift it to the surface.
