genetics

For over a century, biologists have had to contend with a complicated picture of genetics, which they’ve only recently begun to understand.

A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.

A new, deeper understanding of how the breeding structure of species affects their genetic diversity is giving conservationists better tools for saving animals.

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.

Everybody gets older, but not everyone ages in the same way. In this episode, Steven Strogatz speaks with Judith Campisi and Dena Dubal, two biomedical researchers who study the aging process.

When scientists discover genes linked to dangerous illnesses in their samples, how should they convey that news to the study participants? The geneticist Cristen Willer had to tackle that challenge.

Catherine Dulac is overturning preconceptions about “male” and “female” instincts and opening new avenues to treating postpartum depression.

The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.

The unintentional creation of “sturddlefish” hybrids may illuminate the genomic mechanisms that govern whether species can interbreed.
