Frequent fires make droughts harder for young trees, even in wet eastern forests

Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study provides answers.

How birds can detect Earth's magnetic field

Researchers have made a key discovery about the internal magnetic compass of birds. Biologists have identified a single protein without which birds probably would not be able to orient themselves using the Earth's magnetic field.
