An analysis of a unique looping trail of ancient footprints in the United States reveals the dinosaur which made it may have been limping.

Scientists have found wolf remains, thousands of years old, on a small, isolated island in the Baltic Sea – a place where the animals could only have been brought by humans. The study, published in Proceedings of the National Academy of Sciences by researchers at the Francis Crick Institute, Stockholm University, the University of Aberdeen and the University of East Anglia, suggest that grey wolves may have been managed or controlled by prehistoric societies.

Tropical cyclones can unleash extensive devastation, as recent storms that swept over Jamaica and the Philippines made unmistakably clear. Accurate weather forecasts that buy more time to prepare are crucial for saving lives and are rooted in a deeper understanding of climate systems. Driving this forward, researchers at the Institute of Science and Technology Austria (ISTA) and others have successfully identified a previously unknown cyclic climate pattern by historical reanalysis of datasets and satellite observations. The findings are published in PNAS.

Researchers from Kelson Marine in Portland, Maine and the University of Maine developed a new tool that provides detailed economic analyses for kelp farmers and reveals strategies for reducing the cost of farmed seaweed. The tool incorporates many different factors from a farming scenario, including site specific-ocean and meteorological conditions, species-specific crop characteristics and growth, workboat types and sizes, labor structures, operational technology, local shore-side infrastructure, maintenance schedules and more. By resolving the comprehensive impact on the bottom line and the multitude of tradeoffs associated with specific operational and farm design decisions, the tool provides unique insight into the implications of cost-saving alternatives.

To predict sea level changes, a University of Houston scientist has teamed with international partners to deliver an unprecedented view of the massive glaciers in Antarctica and to examine how they are shifting.  

Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.

Research led by polar scientists from Northumbria University has revealed new hope in natural environmental systems found in East Antarctica which could help mitigate the overall rise of carbon dioxide in the atmosphere over long timescales.

As Antarctica's ice sheets thin due to climate change, newly exposed mountain peaks could significantly increase the supply of vital nutrients to the Southern Ocean which surrounds the continent, potentially enhancing its ability to absorb atmospheric carbon dioxide, according to the research published in Nature Communications.
