An international group of researchers including biologists from the University of Maryland found that at least four species of marine ribbon worms independently evolved the ability to regrow a head after amputation.
Researchers are one step closer to solving the mystery of why some vertebrates can regenerate their spinal cords while others, including humans, create scar tissue after spinal cord injury, leading to lifelong damage.
The headlines are eye-catching: Scientists have sequenced the genome of white sharks. Or the bamboo lemur, or the golden eagle. But why spend so much time and money figuring out the DNA makeup of different species?
A team of paleontologists led by Virginia Tech's Michelle Stocker and Sterling Nesbitt of the Department of Geosciences have identified fossil fragments of what are thought to be the oldest known frogs in North America.
Amphibians are victims of lethal skin-disease epidemics. In the first global-scale study, researchers from 31 universities and research centers, including the Smithsonian Tropical Research Institute (STRI), collected skin ...
At least 200 species of large animals are decreasing in number and more than 150 are under threat of extinction, according to new research that suggests humans' meat consumption habits are primarily to blame.
For decades, scientists have assumed that the hundreds of species of salamanders that lack lungs actually "breathe" through their skin and the lining of the mouth, and Harvard researchers are providing the first concrete ...
Researchers at UT have discovered the largest individual of any cave salamander in North America, a 9.3-inch specimen of Berry Cave salamander. The finding was published in Subterranean Biology.
Regeneration is one of the most enticing areas of biological research. How are some animals able to regrow body parts? Is it possible that humans could do the same? If scientists could unlock the secrets that confer those ...
Populations of coastal cutthroat trout and coastal giant salamanders in the Pacific Northwest show the ability to rebound quickly from drought conditions, new research by Oregon State University suggests.
