Cosmic baby steps: For the first time, astronomers witness the dawn of a new solar system

Formation of silicates around the baby star HOPS-315

For the first time, international researchers have pinpointed the moment when planets began to form around a star beyond the sun. Using the ALMA telescope, in which the European Southern Observatory (ESO) is a partner, and the James Webb Space Telescope, they have observed the creation of the first specks of planet-forming material—hot minerals just beginning to solidify. This finding marks the first time a planetary system has been identified at such an early stage in its formation and opens a window to the past of our own solar system.

“For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our sun,” says Melissa McClure, a professor at Leiden University in the Netherlands and lead author of the new study, publishe...

Want to boost your brain as you age? Music might be the answer

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, &...
