One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

Every cell in an animal's body carries the same DNA. Yet that single genetic blueprint somehow produces neurons that fire, muscles that contract, and tissues with entirely different jobs. How ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...

Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from sunlight like plants. The breakthrough could have major benefits for growing ...
