In mammals, males are usually stronger and more competitive than females. Males also show greater inequality in reproductive success—the number of offspring they produce—than females. In spotted hyenas, the opposite is true: Reproductive inequality is greater among females than
Fusion at high temperatures powers the sun and, if harnessed, could provide a potential source of energy here on Earth. But controlling fusion reactions has other benefits. The process also generates subatomic particles called neutrons that are used in a range of applications
Snakes are everywhere in our legends and mythology. Yet for most of us, our blood runs cold whenever we encounter these strangely undulating, scaly tubes of muscle slithering through the leaf litter.
Crop production faces threats from plant pathogens. Traditional disease-resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to particular pathogens. However, rapidly evolving pathogens frequently overcome these natural
