A new study has, for the first time, described the composition of microRNA in dolphin milk and revealed similarities between these molecules and the microRNA found in terrestrial mammals. This discovery will help deepen our understanding of the role milk plays in the development of offspring across different species.
Young male African wild dogs traveled over 4,000 kilometers in nine months, setting a new record among African mammals. This discovery is important for understanding migration patterns and for the conservation of this rare species.
Platypuses have acquired yet another unique feature: their fur contains hollow spherical melanosomes, a type previously unseen in any other vertebrate. This discovery highlights the extraordinary nature of platypuses and, in several ways, brings them closer to birds.
A study has shown that mammal populations in European and North American zoos are aging, which reduces the number of individuals capable of breeding and poses a threat to the conservation of rare species.
