The brain’s 5 eras, the vaccine that protects against dementia, altruistic ants – podcast
  • 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.
  • These findings are crucial as they enhance understanding of human cognitive development and potential interventions for dementia, which is a growing concern in aging populations. The implications of the shingles vaccine could lead to new preventive strategies in healthcare, while the study of ants provides a fascinating glimpse into evolutionary biology and social behavior.
  • The discussions reflect ongoing debates in science regarding cognitive development, the impact of vaccinations on neurological health, and the ethical considerations surrounding animal behavior studies. These themes resonate with broader societal concerns about aging, mental health, and the role of altruism in nature, highlighting the interconnectedness of biological research and its applications in human health.

Having a dog can boost teenagers’ mental health, say scientists
PositiveScience
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.
