A team of paleontologists at the Natural History Museum of Los Angeles County, working with a colleague from the Chinese Academy of Sciences and another with the North Dakota Geological Survey, has identified a new species ...
An animal's brain consists of two different types of cell: neurons, which process and transmit information, and glial cells, which support the neurons in a variety of ways. In 1871, the French anatomist Louis-Antoine Ranvier ...
Plants existed on Earth for hundreds of millions of years before the first flowers bloomed. But when flowering plants did evolve, more than 140 million years ago, they were a huge evolutionary success.
University of Queensland researchers have shown for the first time that some of the world's most painful ant stings target nerves, like snake and scorpion venom. This research is published in Nature Communications.
If you look at enough dinosaur fossils, you'll see that their skulls sport an amazing variety of bony ornaments, ranging from the horns of Triceratops and the mohawk-like crests of hadrosaurs to the bumps and knobs covering ...
Three hundred miles off the southeastern coast of Africa, Madagascar is a land of mystery. There is such a rich diversity of vertebrates found only on the island that is so unlike anything seen elsewhere in the world that ...
Complex multicellular organisms can only emerge from fertilized eggs because embryonic development is biologically precisely regulated. Cellular communication through signaling pathways plays a crucial role in this context. ...
Meet the "tadpole from hell," or to give the species its full name, Crassigyrinus scoticus. Digital reconstructions of broken fossils have revealed more about the life of this ancient crocodile-like predator.
Ever since Mary Schweitzer found soft, stretchy tissue in a T. rex fossil in 2004, scientists have been trying to come to grips with how some biological tissues and cells could preserve within ancient critters.
In humans and other animals, sex is usually determined by a single gene. However, there are claims that in some species, such as platyfish, it takes a whole "parliament" of genes acting together to determine whether offspring ...
