Archaeopteryx is famous as the world’s oldest bird, but reptiles were flying about some 50 million years earlier than that (225 million years ago), even before large dinosaurs roamed the Earth. A new study of extinct reptiles called kuehneosaurs, by scientists from the University of Bristol, England, shows that these early flyers used extraordinary extensions of their ribs to form large gliding surfaces on the side of the body.
Research published in Nature Genetics by a team of international scientists including the University of Melbourne, Department of Zoology, has established an identical mechanism of genetic imprinting, a process involved in marsupial and human fetal development, which evolved 150 million years ago.
Temptation may be everywhere, but it’s how the different sexes react to flirtation that determines the effect it will have on their relationships. In a new study, psychologists determined men tend to look at their partners in a more negative light after meeting a single, attractive woman. On the other hand, women are likelier to work to strengthen their current relationships after meeting an available, attractive man.
Just as people give away their origins by that southern drawl or New England twang, poisonous snakes produce venom that differs distinctly from one geographic area to another, the first study of the “snake venomics” of one of the most common pit vipers in Latin America has found.
Faced with earlier studies stating that the big predators such as tigers, lions, and lynxes fulfil their dietary needs by eating one or two types of prey, scientists from the University of Malaga assure us now that felines need from 5 to 7 different types of prey to fulfil their dietary needs, although they may be more specialised anatomically than the canines (wolves, dogs) who can obtain 100% ingested biomass by eating three types of prey.
An insect, not seen in the UK before, has been discovered living in the Natural History Museum’s Wildlife Garden. The tiny bug is baffling insect experts at the Museum who are still trying to identify the mystery newcomer.
