Not too big, not too small: Why modern humans are the ideal size for speed

Not too big, not too small: Why modern humans are the ideal size for speed

The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title of the fastest level flight (excluding diving) goes to the white-throated needletail swift, at more than 112 km per hour.

Geodynamic mantle-flow model explains deformation of continental crust block in North China

Geodynamic mantle-flow model explains deformation of continental crust block in North China

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's continental crust, cratons have remained largely unchanged for billions of years. Although cratons have survived many geological events, some are undergoing decratonization—a process characterized by their deformation and eventual destruction.

A physicist and his cat 'reveal' the equation of cat motion

A physicist and his cat 'reveal' the equation of cat motion

In the social media age, there is little doubt about who is the star of the animal kingdom. Cats rule the screens just as their cousins, the lions, rule the savanna. Thanks to Erwin Schrödinger, this feline also has a place of honor in the history of physics. And it was Eme the cat that inspired Anxo Biasi, researcher at the Instituto Galego de Física de Altas Enerxías (IGFAE), to publish an article in the American Journal of Physics.
