Sex-specific organ shape is usually thought to depend on sex chromosomes or hormones. Now it emerges that crosstalk between organs sculpts sex-specific 3D gut shape in flies, identifying a new way to ...

We humans love putting things in boxes. Assigning simple categories makes us feel comfortable – but all too often, biology comes along to ruin the fun. Sex is often described in simplistic, binary ...

The development of sex-specific characteristics is frequently seen in mammals. These characteristics stem from the activation of corresponding genetic programs that until now have been largely ...

What is biological sex? It seems like a question with an obvious answer: male and female, of course. You might point to internal or external sex organs, or sex chromosomes (XX for females, XY for ...

The development of sex-specific characteristics is frequently seen in mammals. These characteristics stem from the activation of corresponding genetic programs that until now have been largely ...

Some health officials say mpox cases in Congo appear to be "stabilizing"—a possible sign that the main epidemic for which the World Health Organization made a global emergency declaration in August ...

Surprising pattern: The genetic programmes responsible for the development of sex-specific organ characteristics in mammals are turned on almost exclusively late in the development of the organs, in ...
