Scorpions' weapons are fortified with metal to suit their needs, research shows

As the United States and Israel launched their war on Iran in late February, the social media posts by some US national security agencies took a particular turn.

Researchers at Kyushu University and Institute of Science Tokyo have developed a new computational model that can simulate the transport of oxygen by red blood cells (RBCs) through tiny blood vessels—or capillaries—and their delivery to surrounding tissues. Published in the International Journal of Heat and Mass Transfer on April 27, 2026, the study reveals that RBCs can naturally adjust the amount of oxygen released based on local requirements and help maintain a stable level of oxygen througho

Pollinating insects are important for agriculture and ecological flourishing, but they are difficult to monitor, as identification is tricky, labor-intensive, and typically requires killing some insects. Publishing in PNAS Nexus, Adam Narbudowicz and colleagues use machine learning to identify insects by the changes in their radar reflection, caused by the flapping of their wings. The machine learning model extracted more than 70 harmonic, spectral, and temporal features from the Doppler radar s

In addition to habitat loss and illegal hunting, the jaguar (Panthera onca) faces another threat that increases its risk of extinction in the South American Atlantic Forest: food scarcity. A study by Brazilian researchers has found that the availability of jaguar prey is reduced, even in the protected areas of the biome, which covers approximately 15% of Brazil and extends across 17 states in the South, Southeast, and Northeast regions, as well as parts of Argentina and Paraguay. The paper is pu
