Sediments at the bottom of the ocean can offer a window into the past, indicating environmental conditions not just from the sea but washed in from terrestrial runoff, as well as preserving the flora and fauna of the time. ...
Scientists have unveiled a new mechanism that plants use to sense temperature. This finding could lead to solutions to counteract some of the deleterious changes in plant growth, flowering and seed production due to climate ...
