Noise is a ubiquitous feature for all organisms growing in nature. Noise (defined here as stochastic variation) in the availability of nutrients, water and light profoundly impacts their growth and development. Not only is noise present as an external factor but cellular processes themselves are noisy. Therefore, it is remarkable that organisms can display robust control of growth and development despite noise. To survive, various mechanisms to suppress noise have evolved. However, it is also becoming apparent that noise is not just a nuisance that organisms must suppress but can be beneficial as low noise can facilitate the response of an organism to a sub-threshold input signal in a stochastic resonance mechanism. This review discusses mechanisms capable of noise suppression or noise leveraging that might play a significant role in robust temporal regulation of an organism's response to their noisy environment.
对于所有在自然环境中生长的生物来说，噪声是一个普遍存在的特征。营养物质、水和光照可利用性方面的噪声（此处定义为随机变化）会深刻影响它们的生长和发育。噪声不仅作为外部因素存在，细胞过程本身也是有噪声的。因此，尽管存在噪声，生物体仍能对生长和发育进行稳健的控制，这一点很值得注意。为了生存，各种抑制噪声的机制已经进化出来。然而，越来越明显的是，噪声并非仅仅是生物体必须抑制的麻烦，在随机共振机制中，低噪声能够促进生物体对阈下输入信号的响应，因而噪声也可能是有益的。这篇综述讨论了能够抑制噪声或利用噪声的机制，这些机制可能在生物体对其噪声环境的响应的稳健时间调节中发挥重要作用。
