Kind: research · Impact: low

## In brief

- A study reports a double defence mechanism that protects photosynthesis from extreme heat.
- Photosynthesis in plants and microalgae is highly vulnerable to heat, which is a concern as heat waves become more frequent.
- Source excerpt is truncated; further specifics of the mechanism are not available in the provided sources.

## Why it matters

Heat sensitivity of photosynthesis affects crop yields and carbon uptake, so mechanisms that protect it under extreme heat are relevant to plant and climate science.
