A research group led by University of Tsukuba has examined a fossil in Iwaki City, Fukushima Prefecture, and identified it as the right sternal plate (part of the chest skeleton) of an iguanodontian dinosaur. The size of the sternal plate indicates that it belonged to a small individual with an estimated body length of approximately 3 meters. Since previously recovered iguanodontian specimens from the Upper Cretaceous in Japan appear to belong to larger individuals (exceeding 3 meters in body length), this discovery suggests that smaller iguanodontian individuals also inhabited coastal environments in East Asia.

Over the last quarter of a century, the edge of the summer sea-ice in the Greenland Sea has shrunk steadily northwards. Now, researchers have shown from systematic surveys and field reports that this change has drawn exceptionally large congregations from three species of baleen whales to the coastal waters east of Greenland, adding up to approximately 16,000 animals per summer. The authors concluded that the whales have moved in to feed en masse on capelin, a fish that has recently shifted its geographic distribution northwards towards these exceptionally fast-warming waters.

A research team from the University of Innsbruck and Jinan University investigated how heat and tree emissions, together with nitrogen oxides, intensify the formation of ground-level ozone in megacities, such as Beijing — with a clear result: tree species make the difference.

A short-term climatic shift increased precipitation over East Antarctica between 2021 and 2023, adding enough snow to temporarily balance ice loss from climate change at the continent’s edges.

A new study attributes Antarctica's brief stabilization to a short term climatic shift that increased precipitation over east Antarctica between 2021 and 2023, adding enough snow to temporarily balance ice loss at the continent’s edges.
