Physics Protects Beer, Not Coffee, from Spilling

November 24, 2014 2:00 pm | by NYU Polytechnic School of Engineering | News | Comments

Watch even the most careful waiter bring a cup of coffee to your table, and you’ll realize that carrying liquid is not easy. When set in motion, the coffee starts sloshing, little waves appear and spilling may ensue, leaving you with a half-empty cup. Beer, on the other hand, does not slosh as readily.

Gravity May Have Saved Universe in the Beginning

November 18, 2014 2:00 pm | by Imperial College London | News | Comments

Studies have suggested that the production of Higgs particles during the accelerating expansion of the very early universe should have led to instability and collapse. Now, a team has described how the space-time curvature– in effect, gravity– provided the stability needed for the universe to survive expansion.

November 18, 2014 7:00 am | by Australian National Univ. | News | Comments

Physicists have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons. The ability to control polariton flows in this way could aid the development of completely novel technology to link conventional electronics with new laser- and fiber-based technologies.

Artificial Muscle Can 'Remember' Movements

November 14, 2014 3:02 pm | by Univ. of Cambridge | News | Comments

Researchers from the Univ. of Cambridge have developed artificial muscles that can learn and recall specific movements, the first time that motion control and memory have been combined in a synthetic material. The "muscles," made from smooth plastic, could eventually be used in a wide range of applications where mimicking the movement of natural muscle would be an advantage.

New Crystalline Order has Crystal, Polycrystalline Properties
