A nanoscale view of bubble formation: Using computer simulation, a research team succeeded in modeling the behavior of molecules at the liquid -- gas interface at the nanometer scale, enabling them to describe the boiling process with extreme precision. The findings could be applied to future cooling systems for microprocessors, or to the production of carbon-neutral hydrogen, known as green hydrogen.

Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground and pumped up, if needed. Researchers have now found that low-temperature aquifer thermal energy storage is of great potential in Germany. This potential is expected to grow in future due to climate change.

Corals resistant to disease can rescue more vulnerable corals, UC Davis found. Raising corals with diverse genotypes builds resilience amid disease and climate changes in reefs.

Every year, the cross-shelf transport of carbon-rich particles from the Barents and Kara Seas could bind up to 3.6 million metric tons of CO2 in the Arctic deep sea for millennia. In this region alone, a previously unknown transport route uses the biological carbon pump and ocean currents to absorb atmospheric CO2 on the scale of Iceland's total annual emissions, as researchers report.

Researchers developed a technique to effectively measure the thermal expansion coefficient of two-dimensional materials. With this information, engineers could more effectively and efficiently use these atomically-thin materials to develop next-generation electronic devices that can perform better and run faster than those built with conventional materials.

Carbon fiber-reinforced ultra-high-temperature ceramic (UHTC) matrix composites are extensively used in space shuttles and high-speed vehicles. However, these composites suffer from a lack of oxidation resistance. Recently, researchers tested the heat resistance of these composites at very high temperatures, providing insight into the modifications needed to prevent UHTC degradation. Their findings could have huge implications for the manufacture of space shuttle orbiters.

A new study suggests that ships may be spreading a deadly coral disease across Florida and the Caribbean. The findings could help establish testing and treatment methods to mitigate the risk of further disease spread.

An international team of research scientists has documented the central role of vegetation for Arctic warming. The new results allow us to make more precise climate predictions, with the researchers pointing out that current models remain flawed.

For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.

Over a decade, manta ray populations increased significantly in Raja Ampat archipelago in Indonesia, highlighting the importance of long-term conservation and management measures such as well-enforced Marine Protected Areas (MPAs) and fisheries regulations, says a researcher.

Researchers have created a ring-shaped soft robot capable of crawling across surfaces when exposed to elevated temperatures or infrared light. The researchers have demonstrated that these 'ringbots' are capable of pulling a small payload across the surface -- in ambient air or under water, as well as passing through a gap that is narrower than its ring size.

Researchers are using dust trapped in glacier ice in Tibet to document past changes in Earth's intricate climate system -- and maybe one day help predict future changes.

A new way to 3D-print metals makes the materials stronger and more resilient in extreme thermal environments. The technique could lead to 3D printed high-performance blades and vanes for gas turbines and jet engines, which would enable improved fuel consumption and energy efficiency.

On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years, but there is enormous variation in outcomes, new research has found.

Almost one fourth of Sweden's last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence for widespread cryptic forest degradation across the global north.

Extreme heat often follows tropical cyclones, which can complicate disaster recovery even further, researchers have found.
