Two Become One

Molecular details of sperm-egg fusion shed light on a fundamental mystery.

News New software developed at Brown found a mutation that is closely linked to a protein-altering mutation that is virtually absent in populations around the world, but has a frequency of 27 percent in African hunter-gatherer genome data. Courtesy Ramachandran lab

Adaptive Variation

A new machine learning technique helps detect beneficial mutations in population genetic datasets.
