They encountered a case of melanism in a wild gentoo penguin and detailed their findings in a paper published in the journal Polar Biology. The paper...
Credit: PixaobayGiven dire forecasts suggesting the potential extinction of polar bears by the century's close, it becomes imperative for scientists to establish a means of tracking their population to gauge the effectiveness of conservation endeavors in mitigating the impacts of rapidly disappearing habitats.However, working safely with polar bears (Ursus maritimus) is notoriously challenging due...
Credit: PexelsResearchers have made a significant discovery regarding an ancient and extinct species of skink. The findings, reveal that this prehistoric skink was considerably larger in size compared to any skink species currently in existence.A team of scientists from Flinders University, in collaboration with the South and Western Australian Museums, has confirmed...

A recent study analyzed ancient DNA from Caribbean and Mexican Spanish settlements, revealing that cattle from Africa were imported early in colonization, more than a century before documentation.Although historical records...
Scientists demonstrate that the potential origin of localized bone degradation in cholesteatomas involves bone-derived fibroblasts that produce a protein identified as activin A.Prolonged inflammation in the middle ear can lead to various complications impacting both hearing and balance for individuals. Among these issues, the emergence of cholesteatomas, and abnormal cell accumulations within the ear,...
