In this year-end roundup, Scientific American editors break down how 2025 reshaped science across the board—from sweeping federal upheavals that disrupted long-standing research institutions to public health setbacks driven by vaccine rollbacks and rising measles cases to renewed hostility toward climate science and clean-energy policy and finally to the mind-bending dark energy findings that are shaking up cosmology. Together, their insights reveal how 2025 was a turbulent year for science on Earth and beyond—and what to watch closely in 2026.
