Wingbeat radar signatures let AI sort bees, wasps and other insects

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

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

Why are there so many species of coral reef fish? According to a new study, it's because about 50 million years ago, some fish figured out how to bite food from hard surfaces.

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development could find applications in optical communication systems, analog-to-digital conversion, as well as in devices for generating and processing ultra-high-frequency signals based on photonic technologies.
