The Key to Preventing Future Pandemics May Lie in the Study of Bat Physiology

Biology, Science / Jorge Paka

Being the sole mammal capable of genuine flight, bats have developed a range of distinctive traits that enable their bodies to adapt to the physical demands of nocturnal flapping. Having a resilient physique reduces the likelihood of infections causing significant harm. For species like us, lacking such robust immune systems, possessing the ability to tolerate

Ancient DNA: African-Origin Cattle

Biology, Cell Biology, Science / Ana Kiesse Zeleme

Cattle, now iconic in American lore, were absent from the continent until the Spanish introduced them from Europe via the Canary Islands. 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 suggested a

Decoding Inner-Ear Bone Loss

Biology, Molecular Biology, Science / Ana Kiesse Zeleme

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,
