Some of the most intriguing scientific breakthroughs happen when researchers aren't explicitly looking for them. Take, for example, the pygmy raccoon (Procyon pygmaeus), a critically endangered species that lives only on ...
When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research ...
