Among these cave insects, the females evolved to have penises — twice. The reasons challenge common assumptions about sex.
Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
Jellyfish didn’t need novel genes to take an evolutionary leap in complexity.
A primordial developmental toolkit shared by all vertebrates, and described by a theory of the mathematician Alan Turing, sets the growth pattern for all types of skin structures.
Neither animal, plant, fungus nor familiar protozoan, a strange microbe that sits in its own “supra-kingdom” of life foretells incredible biodiversity yet to be discovered by new sequencing technologies.
The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.
The availability of 16 new mouse genomes will help accelerate research into the genetic underpinnings of human traits and diseases.
What’s easy for a computer to do, and what’s almost impossible? Those questions form the core of computational complexity. We present a map of the landscape.
If and when physicists are able to pin down the metal content of the sun, that number could upend much of what we thought we knew about the evolution and life span of stars.
