  • iconHow tails help geckos and other vertebrates make great strides
    A wagging tail is often associated with dogs' emotions, but the side-to-side motion may also help them take longer strides and move faster, according to a study. The research was done on leopard geckos, which are ideal animals for the study of tail function because they naturally lose their tails as a defense mechanism against predators in a process called autotomy.
  • iconLion conservation requires effective international cooperation
    In response to the alarming population declines of one of the most charismatic representatives of the megafauna, the lion, a team of international wildlife lawyers and lion experts joined efforts to assess the current and potential future role of international treaties regarding the carnivore's conservation.
  • iconDelayed weaning reduces behavioural problems in cats
    Early weaning increases aggression and stereotypic behavior in cats. Based on the study, the recommended weaning age of 12 weeks should be raised by at least two weeks. Delaying weaning is an easy and cost-efficient way of improving the quality of life of cats.

  • iconAdvance achieved in dry preservation of mammalian sperm cells
    In an important advance in the preservation of animal reproductive material, researchers have achieved the first successful drying and rehydration of domestic cat sperm using a rapid microwave dehydration method. More challenging to dehydrate than rodent sperm because of the presence of a centrosome, the rehydrated cat sperm were viable and capable of producing blastocysts. Dehydration preservation allows relatively easy, low-tech storage, which could be important in resource-challenged conditions.

  • iconAncient DNA offers new view on saber-toothed cats' past
    Researchers who've analyzed the complete mitochondrial genomes from ancient samples representing two species of saber-toothed cats have a new take on the animals' history over the last 50,000 years. The data suggest that the saber-toothed cats shared a common ancestor with all living cat-like species about 20 million years ago. The two saber-toothed cat species under study diverged from each other about 18 million years ago.
