    The brain switch that could rewrite how we treat mental illness
    13/12/25 15:38:55
    Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These findings are opening the door to treatments that focus on building strength, not just correcting problems. The work is also fueling a broader effort to keep science open, independent, and accessible.
    Ozempic may offer a surprising bonus benefit for brain health
    13/12/25 14:52:34
    A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection to lowered risk. Researchers caution that the findings show an association, not proof of cause and effect. More rigorous long-term studies are needed to understand the link.

    A long-nosed chameleon hid its true identity for 150 years
    13/12/25 09:26:21
    Scientists have discovered that Madagascar’s iconic Pinocchio chameleon is actually a distinct species now named Calumma pinocchio. DNA from both modern samples and centuries-old museum specimens also exposed another hidden species, Calumma hofreiteri. The study shows that the chameleons’ elongated snouts evolve surprisingly quickly, likely influenced by female mate choice. These findings highlight Madagascar as a hotspot of rapidly diversifying reptile life.
