As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.

Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.

Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Researchers have demonstrated, for the first time, SPDC in a liquid crystal. The results open a path to a new generation of quantum sources: efficient and electric-field tunable.

Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.

Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.

Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.

Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.

Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.

An international team of conservation researchers and practitioners has developed an inclusive inventory approach for tracking global conservation areas, with an emphasis on local data and expertise. Applying this approach across the nine countries spanning the Amazon Rainforest identified a wide array of conservation areas with greater diversity and area coverage than existing tracking systems showed.
