There might be a hard limit to our knowledge of the Universe.
Yet another ocean monster has been discovered.
A recent study sheds light on the evolutionary history of rhinoceroses and their remarkably low levels of genetic diversity.
Sometimes, new combinations of preexisting things revolutionize life.
The brain of an ancient bird offers clues to the survival of its modern-day relatives.
Eight-eyed arachnids can tell when an object's movement is not quite right.
When facing a predator, single cells sometimes unite to defend themselves, paving the way for more complex multicellular life forms to evolve.
Evolutionary success is not about the number of one's children, but one's grandchildren: the children need to survive and pass on their genes.
