Given that plants thrive on atmospheric carbon dioxide, one would expect CO2-induced global warming to benefit vegetation around the world. However, a new research demonstrates that climate change promotes plant growth only to halt it to a near halt afterwards.
Details of how this feedback mechanism operates were pu... |

When various organisms and plants first began conducting photosynthesis, the process did not result in the production of oxygen (anoxygenic photosynthesis). However, in time, a switch occurred, which enabled the emergence of an oxygenic (oxygen-production) version of the process. A team of experts now analyzes how th... |
