The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. When mating ...

A research team studied the current ranges of hundreds of North American trees and shrubs to assess the degree to which species are growing in all of the places that are climatically suitable.

- (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction ...

PROVIDENCE, R.I. [Brown University] -- Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external ...

A branch of physics developed in the latter half of the twentieth century that deals with systems of particles that are far from the near-equilibrium conditions studied in classical thermodynamics and ...

Hoarfrost is a kind of ice crystal made of water. Crystals are structures in which a pattern of atoms or molecules repeats in space. Now, two teams of researchers have figured out that crystals' ...

Crystals are structures in which a pattern of atoms or molecules repeats in space. Now, two teams of researchers have figured out that crystals' repeating patterns can also exist through time. These ...

Entropy isn't well understood in systems that aren't at equilibrium, but a new experiment shows a non-equilibrium phenomenon that actually depends upon entropy. Entropy, the measure of disorder in a ...
