Imagine being tasked with counting every blade of grass in a field, noting every single species as you go. This is not far from the challenge many scientists face when analyzing microscopic samples packed with thousands of tiny particles.

What's the link between the global economy and the climate? Consumption drives extraction and carbon emissions. But there is more. The inequalities of the global economy don't just shape what goes into the atmosphere. They affect our understanding of the climate and our perspectives when it comes to possible solutions.

When Cyclone Gabrielle tore through New Zealand's Tairāwhiti region in 2023, it left behind more than silt and floodwaters.

A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation due to its scarce stone resources and semi-arid landscape, the findings at Velanai Island challenge this long-held belief and offer insights into early raw-material exploitation, seafaring capabilities, and subsistence behavior.

The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement for collaboration on the Rapid Apophis Mission for Space Safety (Ramses) to the near-Earth asteroid Apophis.

A joint research team from Nitto Boseki Co., Ltd. (Nittobo) and Tohoku University has revealed that polyionic liquids (PILs) can achieve high carbon dioxide (CO₂) adsorption when their counter anions are exchanged. This discovery provides a critical new design guideline for the development of high-performance CO2 recovery devices and gas separation membranes.

A huge 11,000-carat ruby has been discovered in Myanmar, state media reported Friday, one of the largest ever found in the country renowned for its precious gemstones.

The molecule cAMP, which plays essential roles in mammalian cells, is less well understood in plants. In a new Science Advances paper, researchers from the Institute of Science and Technology Austria (ISTA) and international collaborators demonstrate that plants use two forms of cAMP in parallel to regulate normal cellular processes and respond to stress, while maintaining crosstalk between them.

Antarctica is being ravaged by a triple-whammy of climate chaos that has melted sea ice to record lows, a new study has revealed. For decades, the frozen wilderness at the bottom of the world defied global warming trends, with ice levels actually growing—until 2015 when it suddenly reversed.

A new study, published in Science Advances, has refined some important details about the moon's largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of the moon. The new details can help guide some of the planning for NASA's upcoming Artemis mission to the moon, which is planned for 2028.
