Scientists have built a better mouse. But rest easy — these mice don’t require improved traps. The new mice may give scientists an advantage in tracing genetic sources of common diseases and ...

The relationship between ethics and science has had a long, complicated history. Although the atrocious Nazi experiments performed in the name of science are 70 years behind us, science continues to ...

Understanding the genetic architecture of differentiation between natural populations is a major goal of evolutionary biology. The genetic basis of adaptive differentiation has been a central focus of ...

Scientists have identified a key gene that was transferred from a Sicilian plant into a close relative in Britain, showing how genetic cross-talk between species can be important for evolution. A ...

Like us, plants rely on an immune system to fight off disease. Proteins that scout out malicious bacterial invaders in the cell and communicate their presence to the nucleus are important weapons in ...
