Researchers developed a way to hide encrypted audio inside synthetic image textures rather than photographs. In 165 automated tests, the method preserved visual quality and achieved bit-perfect recovery across all nine tested audio formats.
In zebrafish, blood flow coordinated the movement of endothelial cells as a developing vascular network remodelled. It was also required for the regression of non-perfused sprouts, with Vegfr3/Flt4 needed when blood flow was low.
A new article proposes a framework for managing coral reefs and other tropical marine ecosystems as human pressures accelerate their decline. It calls for stronger protection, better fishing and pollution controls, climate action, community involvement and sufficient funding.
Natural gas production in Colorado’s Denver-Julesburg Basin increased 73.9% from 2015 to 2021, while ethane emissions from oil and gas facilities fell 63.6%. Methane emissions also declined, by 25.3%, according to top-down estimates discussed in the study.
Researchers reviewed studies of 748 children in sub-Saharan Africa who had confirmed foreign objects in their airways. They reported regional differences in the types of objects involved, along with an overall reported death rate of about 2%, but the evidence was limited and varied between studies.
Firefly communication has inspired a model for finding possible signs of intelligent life among the regular signals produced by astronomical objects. The approach looks for unusual patterns that stand out from their surroundings, rather than trying to decode a message.
Gravity and ground-position measurements recorded changing underground mass before, during and after Santorini’s 2025 earthquake crisis. The results were interpreted as evidence of deeper magma intrusion followed by possible dyke or hot-fluid movement near the Kolumbo fault zone.
Younger adults in Ghana became more likely to lead households between 2000 and 2021, especially those aged 25 to 34. At the same time, market renting became the main form of housing access among young household heads, with unequal access to kitchens and bathrooms persisting.
A study of seafood sold in Asturias, northern Spain, found that some products labeled as native European lobster and razor clams were instead non-native species. Researchers also developed naked-eye DNA tests and used one in a restaurant pilot that detected seafood fraud.
A study finds that gender-based harassment remains widespread across metaverse platforms, including Meta Horizon Worlds, VRChat and Decentraland. It also reports that platform policies and moderation systems are largely reactive and do not adequately account for overlapping forms of disadvantage.
Making college science, technology, engineering and math classrooms more inclusive raised grades for students from marginalized racial and ethnic groups by more than half a letter grade, compared with regular classes. A separate program aimed at building students’ resilience had little beneficial effect.
Researchers found that a sea snail usually considered a subordinate grazer can overgraze localized patches within Tasmanian kelp beds when it becomes unusually abundant. Kelp recovery followed a decline in the snails, while overgrazing persisted where the snails were kept together.
This systematic review and meta-analysis examined survival trends among more than 13,000 people with Duchenne muscular dystrophy across 53 studies. Survival was longer in studies of patients receiving home mechanical ventilation, and survival estimates improved over time, but treatment associations cannot establish that a particular treatment caused longer life.
A systematic review and meta-analysis examined ultrasound measurements of thigh muscle in 536 children admitted to pediatric intensive care units. Across the included observational studies, muscle thickness generally fell during the stay, and about 49% had a reduction greater than 10%.
Women’s perceived safety declined sharply after dark when walking, cycling or using public transport, according to a survey in Australia and New Zealand. Unwanted behaviour was common across parts of the journey, but few respondents reported concerns through formal channels.
