          Bigger Brains and Strong Immunity Linked to Longer Lifespans

          New research reveals that mammals with larger brains and more robust immune systems tend to live longer lives. By studying 46 species, scientists found a clear link between maximum lifespan and the expansion of immune-related gene families.

          Gene Defect Causes Abnormal Brain Size

          Mutations in the gene ZNRF3 can lead to abnormal brain sizes—either too large or too small—causing various neurological symptoms. This gene, known for its role in cancer, is crucial in regulating brain cell production. The study found that specific mutations in the gene disrupt the balance of brain cell development, with potential implications for cancer risk in patients with abnormally large brains.

          Largest Animals Have Smaller Brains Than Expected

          Researchers studied brain and body sizes from 1,500 species, finding that larger animals do not have proportionally bigger brains, challenging long-held beliefs. The study reveals that the brain-body size relationship is curved, not linear. This discovery helps explain why humans and other species deviate from the norm in brain size evolution. The findings provide a simpler model for studying brain evolution across mammals.
