Just as melodies transcend time, playing music holds back age-related neural upregulation, supporting better speech perception in older musicians.

    Long-term musical training may mitigate the age-related decline in speech perception by enhancing cognitive reserve, according to a study published in PLOS Biology by Claude Alain from the Baycrest Academy for Research and Education, Canada, and Yi Du from the Chinese Academy of Sciences.

    Normal aging is typically associated with declines in sensory and cognitive functions...

    NVIDIA’s new AI tool enables precise editing of 3D scenes and photorealistic images

    Over the past years, computer scientists have introduced increasingly sophisticated generative AI models that can produce personalized content following specific inputs or instructions. While image generation models are now widely used, many of them are unpredictable and precisely controlling the images they create remains a challenge.

    In a recent paper presented at this year’s Conference on Computer Vision and Pattern Recognition (CVPR 2025), held in Nashville, June 11–15, researchers at NVIDIA introduced DiffusionRenderer, a new machine learning approach that could advance the generation and editing of imag...

    Is Earth inside a huge void? ‘Sound of Big Bang’ hints so

    If we are located in a region with below-average density such as the green dot, then matter would flow away from us due to stronger gravity from the surrounding denser regions, as shown by the red arrows.

    Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighbouring regions of the universe, astronomers say.

    Their theory is a potential solution to the ‘Hubble tension’ and could help confirm the true age of our universe, which is estimated to be around 13.8 billion years old.

    The latest research – shared at the Royal Astronomical Society’s National Astronomy Meeting (NAM) in Durham – shows that sound waves from the early universe, &...

    Exposure to endocrine-disrupting chemicals in early life, including during gestation and infancy, results in a higher preference for sugary and fatty foods later in life, according to an animal study being presented Sunday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

    Endocrine-disrupting chemicals are substances in the environment (air, soil or water supply), food sources, personal care products and manufactured products that interfere with the normal function of the body’s endocrine system...
