A new study reveals that ocean currents transport fish larvae all over the planet—making nations dependent on the health of spawning grounds in far-flung countries.

Reptiles are rarely regarded as ecosystem engineers — an oversight that’s repeated often when it comes to reptiles, and limits our vision of just how ecologically important they’ve been and how important they might yet be again.

In a human-dominated world where animals face many stresses, removing even a few creatures may have more far-reaching and complex consequences than expected.

Lab-cultured meat might not be all it's cracked up to be. That's the finding of a new study which shows that methods used to produce this futuristic food might pump huge quantities of carbon dioxide into the atmosphere that would linger for centuries to come. But the research has a few critical caveats.

A study that maps climate analogs—matching the predicted future climate in one location to the current climate in another—finds that many North American cities are in for an unfamiliar future.

For many animals, survival in a world of 8 billion humans hinges on avoiding conflict. Now, a new tool, originally developed to anticipate crime outbreaks, could reduce violent tiger encounters by half.

If we inject sun-reflecting particles into the atmosphere, we could create a cooler planet—and it seems logical that this would benefit crops troubled by heat stress. But a new study discovers that geoengineering might harm crops, not help them.

Researchers have new, faster methods of isolating genes to identify, clone, and transfer disease-resistant genes into soybean, wheat, and potato plants.
