By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.

The development of periodic structures in embryos giving rise to the formation of, e.g., spine segments, is controlled not by genes but by simple physical and chemical phenomena.

If you've balanced a laptop computer on your lap lately, you probably noticed a burning sensation. That's because ever-increasing processing speeds are creating more and more heat, which has to go somewhere — in this case, into your lap.
