Scientists uncover surprise origin of wispy cirrus clouds

Scientists using the Very Large Telescope's SPHERE instrument have captured 51 images of dusty rings that are forming young planetary systems around other stars. This unprecedented data set provides valuable insights into the processes of planet formation in various stellar environments.

Scientists have developed a new experimental system aimed at understanding how age-related changes in egg cells increase their susceptibility to chromosomal errors. This innovative tool could significantly advance research in reproductive health and fertility treatments.

A recent podcast featuring science editor Ian Sample, co-host Madeleine Finlay, and science correspondent Hannah Devlin discussed significant findings, including a study revealing that the human brain undergoes five distinct developmental eras, with adulthood commencing in the early 30s. Additionally, new research indicates that the shingles vaccine not only offers protection against dementia but may also slow its progression, alongside insights into altruistic behavior in ants during pathogen infections.

Researchers have found that owning a dog can positively impact teenagers' mental health, leading to lower scores in social problems, aggressive behavior, and delinquency. The study, led by Prof Takefumi Kikusui from Azabu University in Japan, suggests that the presence of dogs may reduce stress and promote the release of oxytocin, a hormone associated with bonding.
