‘Don’t Say Gay’ bills claim to use science to justify a binary definition of sex based on certain traits. But the biology of sex and gender is not so simple.
Humans have been making symbols for numbers for thousands of years. Different cultures developed their own symbols, but all use addition and multiplication, suggesting arithmetic is a universal truth.
A chemist explains how the structure of your hair follicles, your genetic code and environmental factors like humidity influence how hair behaves on a day-to-day basis.
Gender disparities in sport extend to injuries too. Female soccer players are at greater risk for ACL tears than males and it is clear immediate action is needed to address the non-biological factors for the injury.
Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.
Despite the prevalent view that people with large bodies should simply eat less and move more, it’s nearly impossible to fight our genetic heritage or other factors that are not within our control.
There’s no single reason many Asian animals spread to Australia but few went the other way – but climate, geography and the slow drift of tectonic plates all played a role.
Aging is a culmination of factors spanning from your cells to your environment. A number of interconnected processes determine how quickly your body is able to repair and recover from damage.
Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
There are areas of biology that may be considered optional at younger year levels, such as botany, entomology and marine ecosystems. Evolution is not one of these.
A Steller’s sea eagle, native to the Asian Arctic, has traveled across North America since 2021. A scholar questions whether the bird is lost – and how well humans really understand animals’ actions.
