Scientists have been aware for some time that whales contribute to marine ecosystems by "recycling" nutrients. However, the exact impact on ocean productivity was unclear and had not been studied quantitatively. A new study, ...
A new study published in Nature Biotechnology shows that stem cell differentiation is linked to cellular structures called P-bodies, providing a potential means of controlling cell identity. Researchers at Baylor College ...
Climate change is driving many of Australia's native reptiles toward extinction, and the answers to their future survival may lie in the fossil record.
A new study published in the journal Oikos reveals for the first time the critical role polar bears play as carrion providers for Arctic species. Researchers from University of Manitoba and San Diego Zoo Wildlife Alliance, ...
An international, multi-university research team, including scientists from Columbus State University, has unearthed a crucial new piece of the puzzle in the evolution of sharks.
Dinosaur "mummies" couldn't have been further from my mind as I trudged up a grassy knoll on the Zerbst Ranch in east-central Wyoming, followed by University of Chicago undergraduates on a field trip linked to my Dinosaur ...
In the Egyptian Western Desert, where red sandstones and green shales rise above the arid plains of Kharga Oasis, paleontologists have uncovered a fossil that fundamentally reshapes our understanding of crocodile evolution.
Biologists have long been fascinated by the ability of salamanders to regrow entire limbs. Now Harvard researchers have solved part of the mystery of how they accomplish this feat鈥攂y activating stem cells throughout the ...
In vertebrates, calcium is stored in bones, and its release is tightly regulated. Now, using fruit flies as a model organism, researchers at University of Tsukuba have shown that even animals without bones possess specialized ...
