The second law of thermodynamics delineates an asymmetry in how physical systems evolve over time, known as the arrow of time. In macroscopic systems, this asymmetry has a clear direction (e.g., one can easily notice if ...
Even if you don't know it by name, everyone is familiar with Newton's third law, which states that for every action, there is an equal and opposite reaction. This idea can be seen in many everyday situations, such as when ...
(Phys.org) —As one of the pillars of the natural sciences, thermodynamics plays an important role in all processes that involve heat, energy, and work. While the principles of thermodynamics can predict the amount of work ...
Eric DeGiuli, a physicist at École Normale Supérieure, has proposed that a human language grammar can be viewed as if it were a physical object, allowing theories such as those in statistical mechanics to explain how a ...
Researchers from the University of Colorado Anschutz Medical Campus and the University College London have developed a new theory of molecular evolution, offering insights into how genes function, how the rates of evolutionary ...

(Phys.org) —In many regards, a brief time-lapse video can teach more about embryonic development than any amount of reading. It is hard not to be impressed how a repeatable form reliably emerges despite considerable variation ...
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) -- A man lifts his hand in the air, and broken pieces of ceramic lying on the sidewalk spring up into his hand, coming together to form a flower pot. He lifts his hands again, and more broken pieces spring together ...
Scientists have for the first time revealed how blue-green algae—visible as the slippery green slime in stagnant water, riverbeds, and seashores—weaves itself into large weblike structures.
