A genetically engineered ferret could help reveal how humans got their big brains.
By inactivating a gene linked to abnormally small brain size in humans, researchers have created the first ferret with a neurological mutation. Although the original impetus of the work was to study human brain disease and development, says Howard Hughes Medical Institute (HHMI)...
The lengths that some males go to attract a mate can pay off in the short-term. But according to a new study from scientists at the Smithsonian's National Museum of Natural History (NMNH), extravagant investments in reproduction also have their costs.
By analyzing the fossils of thousands of ancient crustaceans, a team of scientists led by...
For more than 40 years, frog populations around the world have been declining. Now, a new study reports that some Central American frog species are recovering, perhaps because they have better defenses against a deadly fungal pathogen.
"It's a hopeful, optimistic chapter," said Louise Rollins-Smith, PhD, associate professor of Pathology, Microbiology and Immunology, and a co-author...
An Oxford University collaboration has shed light on the origins of some of South East Asia's most iconic and unique wildlife; the 'deer-pig' (Sulawesi Babirusa), 'warty pig' and the 'miniature buffalo.' In doing so, the research has revealed that Sulawesi, the island paradise where they were discovered, is younger than previously thought.

By studying calcium in fossil remains in deposits in Morocco and Niger, researchers have been able to reconstruct the food chains of the past, thus explaining how so many predators could coexist in the dinosaurs' time. This study, conducted by the Laboratoire de géologie de Lyon: Terre, planètes et environnement (CNRS/ENS de Lyon/Claude Bernard Lyon...
An international team of scientists led by Swansea University biologists describe how novel technologies are transforming our understanding of why wild animals form different groups.
Combining animal tracking data with environmental data from satellites or drones means that scientists can begin to study whole groups and their interactions in the real, changing environments in which they...
