The brain of adult men is approximately 10% larger than that of women. Because men are typically taller and have more muscle mass than women, their brains require more neurons to control the body.
Astronomers found 52 binaries of main-sequence stars and white dwarfs in open clusters using AI and Gaia data. These systems reveal the common-envelope phase, crucial for studying stellar evolution, supernovae, and gravitational waves.
Curly hair may have offered evolutionary advantages
Studies suggest curly hair could have aided heat regulation and brain protection in early humans by trapping air and shielding the scalp from UV radiation more effectively than straight hair.
