Morris Animal Foundation-funded researchers from the University of Sydney have found a previously undiscovered hepadnavirus in an immunocompromised cat, and subsequently in banked samples. The research team published their results today in the prestigious journal Viruses.
The method reduces ice crystals that form during cryopreservation and affect spermatozoon structure.
Mosquito saliva alone -- even in the absence of any pathogens -- contains hundreds of proteins. Now, researchers reporting in PLOS Neglected Tropical Diseases have discovered that the interaction of these proteins with the human immune system causes an immune response that can be detected for days after a mosquito bite.
Data about marriages in Iran points to the declining number of formal (arranged) marriages in recent decades despite strong cultural and religious traditions favoring such marriages.
Scientists have started to crack the 50-year-old puzzle of how temperature turns baby turtles male or female. In a study in the journal Science, researchers show that cooler egg incubation temperatures turn up a key gene called Kdm6b in the turtle's immature sex organs. This in turn acts as a biological 'on' switch, activating other genes that allow testes to develop without altering the underlying genetic code.
Researchers at the University of Liverpool have turned to the popular video-sharing site YouTube to study the complex issue of dog bites. Preventing dog bites is an increasingly important public health and political issue. However, it remains difficult for researchers to understand the circumstances leading up to dog bites, with most studies relying on evidence collected after bites happen. In a new study researchers have, for the first time, used YouTube videos to directly observe and analyse dog bites in situ.
New research shows that same-sex mating among male insects is more likely to be due to incompetence rather than sexual preference. More than 100 species of insects engage in same-sex mating behavior, and in some species the same-sex mating is more common than heterosexual mating. The research team studied the red flour beetle to find out why.
A deadly fungus responsible for the devastation of amphibian populations around the world may have originated in East Asia, new research has found.
Using machine-learning techniques, a research team has reconstructed a short movie of small, randomly moving discs from signals produced by rat retinal neurons. Vicente Botella-Soler of the Institute of Science and Technology Austria and colleagues present this work in PLOS Computational Biology.
Ants working together to carry a large piece of food get around obstacles by switching between two types of motion: one that favors squeezing the morsel through a hole and another to seek a path around the barrier. Jonathan Ron of the Weizmann Institute, Israel, and colleagues present these findings in PLOS Computational Biology.
