Researchers in China have discovered that collagen isolated from the skin of tilapia effectively reduce wound healing time in mice. The usefulness of collagen, a major structural protein found in connective tussues, in wound healing has been known. Using fish proteins instead of typical mammalian sources reduces the risk for potential pathogens.
Dr. Jiao Sun (Shanghai Jiaotong University School of Medicine) and colleagues isolated collagen from the skin of tilapia and spun…
edyong | April 30, 2009These cells look like fairly typical bone cells. They appear to be connected to each other by thin branch-like projections and are embedded in a white matrix of fibres. At their centres are dark red spots that are probably their nuclei. But it's not their appearance that singles out these extraordinary cells - it's their source. You're looking at the bone cells of a dinosaur.
They come from an animal called Brachylophosaurus, a duck-billed dinosaur that lived over 80 million years ago. By looking at one of its thigh bones, Mary Schweitzer from North Carolina State University has managed to…

Some of you might remember a paper published in Science that rocked the paleontological world by revealing that a broken thigh bone from Tyrannosaurus rex contained soft tissue. When this soft tissue was analyzed, it was identified as…
