THE tenets of physics can seem carved in stone. The speed of light is a constant. There are four fundamental forces. Theoretically, rules like these are open to revision. But new contenders had better ...

In a development that could shift our basic understanding of fluid mechanics, researchers from Drexel University have reported that, given the right circumstances, it is possible to induce a simple ...

Scientists have discovered something that seems almost impossible: under the right conditions, ordinary liquids can snap apart like solid objects. In experiments, researchers found that when certain ...
