In physics, equilibrium is a state in which a system's motion and internal energy do not change over time. Videos of systems in equilibrium would look exactly the same if they were watched in their normal chronological progression ...
All living things must obey the laws of physics—including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear to contradict this ...

(PhysOrg.com) -- Scientists have known for 40 years that even though it takes longer to use sign language to sign individual words, sentences can be signed, on average, in the same time it takes to say them, but until now ...
A promising new metal alloy system could lead to commercially viable magnetic refrigerants and environmentally friendly cooling technologies, according to a scientist at Rochester Institute of Technology.
