• Scientists Say a Major Assumption About Parkinson’s Disease May Be Wrong

  31-12-2025 19:14 via scitechdaily.com
  A new study suggests dopamine may not directly control how fast or forcefully movements are made, challenging a long-standing view in neuroscience. New research led by McGill University is questioning a widely held idea about how dopamine influences movement, a finding that may change how scientists approach treatments for Parkinson’s disease. The study, published in [...]

• A 30-Year Superconductivity Mystery Just Took a Sharp Turn

  31-12-2025 14:29 via scitechdaily.com
  New research sharpens understanding of the hidden symmetry in a mysterious superconductor. Superconductors are materials that allow electrical current to flow without any resistance, a property that typically appears only at extremely low temperatures. While most known superconductors follow established theoretical frameworks, strontium ruthenate, Sr₂RuO₄, has remained difficult to explain since researchers first identified its [...]
