Plant CO2 uptake rises by nearly one third in new global estimates

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Plants the world over are absorbing about 31% more carbon dioxide than previously thought, according to a new assessment developed by scientists. The research, detailed in the journal Nature, is expected to improve Earth system simulations that scientists use to predict the future climate, and spotlights the importance of natural carbon sequestration for greenhouse gas mitigation.

Replacing hype about artificial intelligence with accurate measurements of success

DOE/Princeton Plasma Physics Laboratory
Peer-Reviewed Publication

A new paper in Nature Machine Intelligence notes that journal articles reporting how well machine learning models solve certain kinds of equations are often overly optimistic. The researchers suggest two rules for reporting results and systemic changes to encourage clarity and accuracy in reporting.
