Mutant Maps
Struck by an analogy between genetic mutations and flaws in antique printed documents, a biologist has devised a method to analyze such flaws to pinpoint publication dates of rare, undated documents.

Evolution’s Mystery Woman
A heated debate has broken out among anthropologists over whether a highly publicized partial skeleton initially attributed to a new, tiny species of human cousins actually comes from a pygmy Homo sapiens with a developmental disorder.

This article reviews efforts to explain why certain biological molecules tend to be all right-handed (e.g., sugars) or left-handed (e.g., amino acids). An explanation might lie in the evolution of enzymes involved in their synthesis. For example, the fact that some organisms produce predominantly d-alanine could be explained by random mutations for the opposite enzyme […]

Möbius at Fermilab
Fermilab’s Wilson Hall. Courtesy of Fermilab. Soaring into the sky like a medieval cathedral, the twin towers of the structure known as Wilson Hall dominate the flat countryside surrounding the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill. Named for physicist and accelerator builder Robert Rathbun Wilson (1914-2000), the building celebrates Wilson’s vision and skill, […]
