A new study from Tel Aviv University has predicted, for the first time, the groundbreaking results that can be obtained from detecting radio waves coming to us from the early Universe. The findings show that during the cosmic dark ages, dark matter formed dense clumps throughout the Universe, which pulled in hydrogen gas and caused it to emit intense radio waves. This leads to a novel method to use the measured radio signals to help resolve the mystery of dark matter.

In a paper published in SCIENCE CHINA Earth Sciences, a team of researchers conducted a comprehensive analysis of carbon and silicon burial in a river-dominated estuary. This study provides a robust method for examining changes in carbon preservation associated with silicon under the increasing anthropogenic nutrient inputs in coastal water.

A study published in Science China Earth Sciences (Issue 9, 2025) has quantitatively reconstructed changes in nitrate availability in the Early Triassic ocean by systematically integrating global nitrogen isotope records and applying a nitrogen cycle box model. The research reveals significant temporal evolution and spatial variability in nitrate availability during this period. By correlating multiple paleoenvironmental proxies, the study uncovers the underlying mechanisms of the evolution of nitrate availability and suggests that prolonged nitrate depletion likely played a key role in delaying the recovery of marine ecosystems after the end-Permian mass extinction. These findings provide new insights into the processes governing ecosystem recovery following major extinction events, offering a clearer understanding of past environmental challenges.

Scientists from Switzerland and Germany have described a new ichthyosaur species from Upper Franconia, Germany. Named Eurhinosaurus mistelgauensis after the fossil-rich clay pit of Mistelgau, the discovery is based on specimens excavated and curated by the Urwelt-Museum Oberfranken, which has conducted regular fieldwork at the site since 1998.
