Using X-ray-based technology developed at Brown University, researchers uncover shared subsurface movement patterns between birds and dinosaurs, adding a new dimension of fossil track diversity.
New insight on how four species of seabirds have developed the ability to cruise through both air and water has been published today in the open-access journal eLife.
Infant marsupials and monotremes use a connection between their ear and jaw bones shortly after birth to enable them to drink their mothers' milk, new findings in eLife reveal.
A research team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) has now unlocked the secrets of true coloration in the 99-million-year-old insects.
The latest supplement to the American Ornithological Society's Checklist of North and Middle American Birds, published in The Auk: Ornithological Advances, includes several major updates to the organization of the continent's bird species, including the addition of the Mexican Duck and the removal of the Northwestern Crow. The official authority on the names and classification of the region's birds, the checklist is consulted by birdwatchers and professional scientists alike and has been published since 1886.
A new study analyzes the genomes of 29,255 E. coli strains collected between 1884 and 2018 to examine the evolution of 409 different genes that enable the bacterium to resist various antibiotics. The researchers examined whether the genes that confer antibiotic resistance, once acquired, tended to unusually accumulate -- a phenomenon known as "genetic capitalism" -- or disappear because they are unused, through a normal evolutionary process known as "stabilizing selection." Recently, genetic capitalism is found common.
New Zealand's monster penguins that lived 62 million years ago had doppelgangers in Japan, the USA and Canada, a study published today in the Journal of Zoological Systematics and Evolutionary Research has found.
For more than 20 years, Virginia Tech biomedical engineering and mechanics professor Jake Socha has sought to measure and model the biomechanics of snake flight and answer questions about them, like that of aerial undulation's functional role.
Modelling of the Chicxulub asteroid impact 66 million years ago shows it created a world largely unsuitable for dinosaurs to live in.
A giant marsupial that roamed prehistoric Australia 25 million years ago is so different from its wombat cousins that scientists have had to create a new family to accommodate it.
