UN warns of 'deepening crisis' in oceans, urges action‎

Oceans are in a "deepening crisis" that demands urgent global action, a major U.N. report warned Monday, with seas warming and rising faster, ice cover shrinking, and marine ecosystems under mounting strain.

How did a major mangrove restoration project in Senegal end up selling 'ghost carbon?'‎

Nature-based solutions have become central to global climate strategies. From tropical forests to wetlands, restoring nature means trees and plants can capture carbon dioxide, reduce global warming, and regenerate biodiversity.

Neutron star merger simulations gain new precision with AI-driven r-process heating‎

Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For the first time, the scientists used deep learning with a neural network to model the energy release during r-process nucleosynthesis in hydrodynamic simulations. The results are published in the journal Physical Review D.

Physicists create new family of Schrödinger-cat states‎

Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger's cat, imagined as being both alive and dead until it is observed. In the laboratory, physicists can create less dramatic but very real versions of this effect by placing atoms, light or motion into two distinct quantum states at once. Creating and controlling these superpositions is essential for applications ranging from quantum computing to precision timekeeping.

Recovered wild maize gene boosts crop protein without yield loss‎

Maize (Zea mays L.) plays an important role in global food security. During 9,000 years of maize domestication and breeding, however, protein content was not a major breeding target. Consequently, many beneficial gene variants associated with higher protein content were gradually lost from cultivated maize. As a result, modern maize varieties often have low seed protein content, leading to a heavy reliance on imported soybean meal for livestock feed.

What happens when the world's breadbaskets start failing simultaneously?‎

Agriculture today is a massive, globally interconnected industry. That interconnectivity has brought jobs and varied foods to people who might not otherwise be able to access them.

Tabletop experiment helps reconcile fundamental physics‎

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that have never been fully reconciled.

How Facebook users affected by data breaches react over time examined‎

A new study by Mannheim Business Administration professor Hartmut Höhle examines the reactions of actual victims of the Cambridge Analytica scandal on Facebook over a longer period. Its key finding is that, despite being affected by data fraud, users remain on the platform.
