Physicist Proposes Solution to Arrow-of-Time Paradox
Thought experiment proposed to reconcile psychological versus thermodynamic arrows of time
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
Atoms at negative absolute temperature: The hottest systems in the world
(Phys.org)—In cold regions on earth, negative temperatures on the Fahrenheit or Celsius scale can often occur in winter; in physics, however, they were so far impossible. On the absolute temperature scale ...

Second Law of Thermodynamics May Explain Economic Evolution
Physicist finds that E. coli replicate close to thermodynamic limits of efficiency
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 ...
