Could this natural protein be the key to reversing age-related memory loss?
Publicado em 17 de maio de 2025
A new study published in Aging Cell has identified a promising molecule that may help reverse cognitive decline associated with both normal aging and Alzheimer’s disease. Scientists found that increasing the levels of a protein called Hevin—secreted by astrocytes, a type of support cell in the brain—improved memory and learning in middle-aged mice. The intervention worked in both healthy animals and those genetically modified to model Alzheimer’s disease, and it did so [...]

Brain’s ‘threat detector’ uncovered: New study reveals neural circuit for identifying and remembering threats
Publicado em 24 agosto 2024Imagine a mouse, tentatively exploring its surroundings, its senses alert to any sign of danger. In one part of its environment, the mouse has experienced something deeply unpleasant—a mild but startling shock. As it roams, it pauses near the spot where the shock occurred, its behavior changing noticeably. It stretches out, sniffs the air, and hesitates to step back into the area where it was hurt. What’s happening in the mouse’s brain during these moments of heightened [...]ver notícia -
Autism severity rooted in embryonic brain growth, study suggests
Publicado em 02 julho 2024A new study has uncovered an important factor behind the varied outcomes observed in children with autism. Researchers at the University of California San Diego found that differences in the biological development of the brain during the first weeks and months of embryonic growth play a significant role in the severity of autism symptoms later in life. This discovery, published in the journal Molecular Autism, provides a deeper understanding of why some children with autism develop severe, [...]ver notícia -
Huge study links ultra-processed foods to heightened depression risk
Publicado em 27 maio 2024Recent research published in the journal Clinical Nutrition reveals a significant link between high consumption of ultra-processed foods and an increased risk of developing depression. This study, conducted in Brazil, indicates that individuals adhering to diets rich in ultra-processed foods are more likely to experience depressive symptoms over time. These findings underscore the potential mental health risks associated with dietary patterns characterized by processed and convenience [...]ver notícia
