- Oswald Steward wins 2026 Kavli Prize in Neuroscience for discovering neurons manufacture proteins near synapses.
- Local protein synthesis within neurons is fundamental to learning, memory, and brain plasticity.
- Steward's research used radioactive amino acids and electron microscopy, revealing polyribosome clusters at synapses.
- Messenger RNA enables proteins to be made locally at synapses, avoiding transport issues and explaining synaptic plasticity.
- This discovery provides insights into neurological disorders like Fragile X syndrome and Alzheimer's disease.
- Steward believes AI lacks genuine originality, and neuroscience will more likely inform AI than vice versa.
- Scientific breakthroughs are highly dependent on social interactions and collaboration among researchers.
- The 'spark' of new ideas emerging from the brain remains a profound, unexplained mystery in neuroscience.
