Electrolysis can reduce CO2 to CO, a raw material for chemical products such as fuels. Within the GreenQUEST project, an international team led by HZB chemist Prashanth Menezes has systematically investigated catalyst layers made of silver nanoparticles, varying both particle size and density.
When a spacecraft reenters Earth's atmosphere at hypersonic velocities, its protective heat shield faces extreme conditions, including temperatures beyond 3,000 degrees Fahrenheit (1,650 degrees Celsius). To survive, the shield relies on specialized materials that absorb heat as they degrade in a controlled process called ablation, sacrificing the shield's outer layers to protect the vehicle and crew within.
A team of INRAE scientists, in collaboration with Université Côte d'Azur and Nanjing Agricultural University in China, has used an innovative AI-based method to identify the sex pheromone of the lily moth1 and the olfactory receptors associated with it. The insect pest, whose caterpillars feed on these plants, is found in Asia and Oceania. This approach to identifying previously unknown molecules opens up new possibilities for identifying pheromones in other species. These molecules play a key role in certain biocontrol strategies currently used to protect crops, particularly in France. The results were obtained as part of the EXPLOR'AE program and published in BMC Biology.
In 1967, a Malawian farmer stumbled upon a hidden hoard of eight copper ingots buried beneath a tree. Now, more than half a century later, scientists have traced the metal to its source: a copper mine nearly 800 km (500 miles) away.
A new study from Ben-Gurion University of the Negev (BGU) has identified a molecular switch that controls whether stressed human cells activate a survival mechanism or trigger programmed cell death (apoptosis). The findings, published in Redox Biology, provide insights that could help overcome chemotherapy resistance in aggressive tumors.
A research team from The Education University of Hong Kong (EdUHK) and East China Normal University (ECNU) has published a meta-analysis demonstrating the impact of digital textbooks (DTs) on student motivation. Synthesizing 27 experimental and quasi-experimental studies conducted between 2000 and 2024 with 3,590 participants, the study confirms that DTs significantly enhance students' intrinsic learning motivation compared with traditional paper textbooks.
More than 40 million people in the northeastern United States braced Friday for heavy rain and strong winds as an unusually powerful storm for the season was forecast to crash into the region.
Bangkok authorities declared a flood disaster across the Thai capital on Saturday after almost 48 hours of heavy rain left canals full, roads submerged and residents wading through deep water.
Wildfires that tore through Indonesian Borneo's vast tropical forests have increased pressure on critically endangered Bornean orangutans, the International Union for Conservation of Nature (IUCN) said Saturday.
In a freshwater canal surrounded by mangroves in southern Guatemala, hundreds of baby tropical gars—a torpedo-shaped fish with an alligator-like snout dubbed the "fossil fish"—are released into the wild.
