Phys.org / Leafy camouflage reshapes katydid love songs, making males more attractive to females

New research from the University of St Andrews has discovered that insects who conceal themselves as leaves also use their leafy camouflage to amplify mating calls, making themselves more attractive to the opposite sex. The ...

Phys.org / Lab evolution recreates COVID's path to omicron in months, reveals key conditions

A key step in the origin of many pandemics occurs when an animal-borne virus infects humans and then evolves to spread more efficiently from person to person. That is why scientists and physicians keep a close watch on viruses ...

Phys.org / Nine decades of changing insect diversity in Switzerland expose a striking divide

Thanks to a historical data archive, Swiss researchers are able to draw conclusions about the changes in the diversity of two insect groups over the past 90 years. The study, led by Agroscope, identified a significant decline ...

Phys.org / Antarctic 'sky rivers' deliver up to 90% of snowfall, 3D algorithm suggests

Atmospheric rivers act like "rivers in the sky," shuttling intense bands of warm, heavy moisture from lower to higher latitudes. When an atmospheric river encounters cold air or mountainous terrain, the moisture it carries ...
