Natural weathering processes are removing CO2 from the air in a wide range of environments across continents and ocean. Until recently these ‘CO2 vacuum cleaners’ were often studied separately, without properly examining their complex interactions. Now, an international team of Earth scientists is proposing an integrated vision of the many factors that influence the removal of atmospheric CO2 from the highest mountain peaks to the deep ocean floor, including their various interactions. The so-called weathering continuum provides a much more complete picture on what controls and regulates the natural removal of CO2, which could help in the development of enhancing weathering techniques.
A new study combines eye tracking and artificial intelligence to identify the exact moments in an educational video that matter for learning in children. The study could also predict how much children understood from the video based on their eye movements while they were watching it.
