Overheated Australian Trees Rewrite The Book On Photosynthesis With Unique Self-Cooling Method

The year-long experiment showed that trees continue to release water through their leaves as an evaporative cooling system during periods of extreme heat, despite the carbon-fixing process of photosynthesis grinding to a halt. Previously, scientists believed that photosynthesis and transpiration – the process of releasing water – were linked, meaning one would not occur without the other. (Click on title for full story.)
