21 March 2025/Kiel/Rønne. It is well known that the Baltic Sea is contaminated with remnants of munitions from past wars. However, many questions remain about the exact locations of these munitions and their condition after decades under water. Three major projects at national, Baltic Sea and European level are currently working to consolidate existing knowledge and develop technologies to safely identify submerged munitions. GEOMAR Helmholtz Centre for Ocean Research Kiel is contributing to these efforts with three Baltic Sea expeditions. The first mission has now begun: the research vessel ALKOR is testing and further developing state-of-the-art mapping and analysis techniques in German and Danish waters, with a particular focus on the sea areas at the exit of the Flensburg Fjord / Lille Belt, west of Bornholm and the Bay of Lübeck.

Before the US dietary guidelines are revised, the US Department of Agriculture and Department of Health and Human Services convene an independent advisory committee of nutrition experts, who are tasked with digging into the latest research and using data to answer specific, unanswered questions about diet and nutrition. The committee’s findings, along with comments from the public, inform the federal government's updated guidelines.

Cornell University bee experts are analyzing samples of bees and related material to help identify the cause of unprecedented managed honeybee losses this winter.

Key agreements in the “Law of the River,” which encompasses more than 100 years of regulations, laws, court decisions and more focused on managing the Colorado River, are set to expire next year. First established in 1922 as the Colorado River Compact, the guidelines split water management and allocation among seven states. Now, those states — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — are renegotiating the terms of use for the water. Drought, increased temperatures and decreased snowpack in the Rocky Mountains are complicating the matter, according to Antonia Hadjimichael, assistant professor of geosciences at Penn State.
