Climate change causes landfalling hurricanes to stay stronger for longer

Climate change is causing hurricanes that make landfall to take more time to weaken, reports a new study. Researchers showed that hurricanes that develop over warmer oceans carry more moisture and therefore stay stronger for longer after hitting land. This means that in the future, as the world continues to warm, hurricanes are more likely to reach communities farther inland and be more destructive.

Silicone surface mimics topology, wettability of a real human tongue

The tongue helps people taste food, but structures on its surface also help them sense textures -- something that's also very important when savoring a meal. Now, researchers have made a 3D silicone surface that, for the first time, closely mimics the surface features of the human tongue. The material could help food scientists study mechanical interactions of foods, liquids and medicines with the organ.
