New research has found that swapping steak for salmon once a week significantly reduced food-related carbon emissions by 28 % in the long-term, this is equivalent of a return flight from London Heathrow to Marrakech, Morocco.

An electronic nose developed at UC Berkeley can detect signs of food spoilage and common allergens more accurately than the human nose. Using gas sensors and machine learning, the chip could one day help smart fridges warn consumers before milk, chicken or other foods go bad.

A study in Spain and Japan suggests that people tend to turn counterclockwise when moving in groups, regardless of culture, gender or handedness. The finding could offer new insights into human locomotion, crowd dynamics and the design of public spaces.

A recent study has revealed that valvular heart disease is common in cancer patients and that interventions to treat this disease significantly improved survival.

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 itself. The new device doesn’t rely on a battery-powered control method, removing an expensive component of such systems.

New genomic research traces the domestication of modern upland cotton to Mexico’s Yucatan Peninsula. By analysing wild cotton populations, researchers have identified a rich genetic reservoir that could help breeders recover traits lost during domestication, including disease resistance and salt tolerance.

A molecular material developed at Kyushu University can convert visible sunlight into ultraviolet light under ordinary outdoor conditions. The solid-state system uses photon upconversion to generate UV light from lower-energy photons, opening potential applications in air purification, photocatalysis and low-intensity 3D printing.

A new study has revealed that paid paternal leave plays a crucial role in the mental health of new dads. In the absence of this, new dads witness higher levels of anxiety and depression.

A one-square-metre solar reactor developed at the University of Cambridge shows how plastic waste such as PET bottles can be converted into clean hydrogen and valuable chemicals under real-world outdoor conditions. The scalable approach marks a step towards commercial solar-powered recycling, though durability and efficiency still need further development.

An international team of researchers has published a new review in Animal Behaviour revealing how communication enables cooperation between different animal species. The review highlights how movements, visual displays, calls, and other behavioural cues and signals help partners coordinate interactions and align interests across species boundaries.
