A successful reintroduction program for one-horned rhinos has been implemented in Nepal over the past few decades. However, few studies have examined functional recovery following reintroduction.
Suddenly they appear, and like the SARS-CoV-2 coronavirus, can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic ...
Researchers from the Hubrecht Institute's Kops group, in collaboration with researchers from the University of Edinburgh, have made a surprising new discovery in the structure of the centromere, a structure involved in ensuring ...
Evidence in lampreys for the presence of a rudimentary sympathetic nervous system, previously thought to be unique to jawed vertebrates, has been presented in Nature. The finding may prompt a rethink of the origins of the ...
Competition between species played a major role in the rise and fall of hominins—and produced a "bizarre" evolutionary pattern for the Homo lineage—according to a new University of Cambridge study that revises the start ...
Seven hundred million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today's standards, the animal had a front and a back, a top and a bottom. This was a groundbreaking ...
Early jawless fish were likely to have used bony projections surrounding their mouths to modify their mouth shape while they collected food.
Axolotls (Ambystoma mexicanum) are a critically endangered species of salamander. The species has only one natural habitat remaining, a series of canals in Mexico City, and only 50 to 1,000 axolotls are estimated to be left ...
Whether human or reptile, in the skull of most terrestrial vertebrates there is a gaping hole in the temple; in the case of most reptiles, there are two. Scientists have been looking for explanations for this for 150 years.
