Researchers have discovered a new organism that has no known evolutionary relatives, causing them to reconsider how genes evolve.
Why one scientist changed his mind on using gene drives for conservation.
Recent advances in laboratory methods are enabling scientists to recover very old or degraded DNA sequences from warmer places, where DNA degrades at a much faster rate.
The morality of human embryonic stem cell research has long been contentious, but new discoveries could end the controversy.
Genetic tests are becoming increasingly common, but a major medical organization argues that we should be cautious about testing children.
Despite the recent discovery of the "blonde gene," environmental differences and genetic effects remain inextricably linked.
Epigenetics is a hot field right now, and while many recent findings aren't nearly as revolutionary as its practitioners believe, we have seen some provocative study results that are hard to dismiss.
