Plants in space

How plants handle stress in space and what astronauts can learn from them is the subject of a new study at Michigan State University.

Scientists present first model of how buds grow into leaves

Leaves come in all shapes and sizes. Scientists have discovered simple rules that control leaf shape during growth. Using this 'recipe', they have developed the first computer model able to accurately emulate leaf growth ...
