Materials Around Us Are Defined by Water Molecules

A study upends the paradigm that the atoms and molecules that make up the natural world define the character of solid matter, and argues that the character of many biological materials is actually created by the water that permeates these materials.

Coos and Snooze: Scientists Decode Pigeons’ Dreams

The boundless and bizarre content of human dreams has attracted the interest of biological researchers for decades. A new study by German scientists shows that pigeons dream too. The team used a technique called functional magnetic resonance imaging (fMRI) to look at bird brain areas that lit up during sleep.
