PERCEPT: Replacing binary p-value thresholding with scaling for more nuanced identification of sample differences

iScience
Summary: Key to a biologists’ capacity to understand data is the ability to make meaningful conclusions about differences in experimental observations. Typically, data are noisy, and conventional methods rely on replicates to average out noise and enable

Effects of environmental feedback on species with finite population

iScience
Summary: In an unchanging environment, natural selection always selects species with high fitness. In this study, we build a co-evolutionary system to study the interaction between stochasticity in finite populations and environmental feedback.
