The antioxidant drug ebselen can prevent sexual transmission of Zika virus from male to female mice, according to new research published in PLOS Pathogens by Yogy Simanjuntak and colleagues at Academia Sinica, Taipei, Taiwan. The results hint at a potential role for ebselen in preventing Zika spread among humans.
The majority of Californian Anna's Hummingbirds appear to have P. huitzilopochtlii feather mites on their tail flight feathers, according to a study published Feb. 14, 2018, in the open-access journal PLOS ONE by Youki Yamasaki from Washington State University, US, and colleagues.
Digital dissection shows that two horseshoe crab appendages -- the pushing leg and the male pedipalp -- each have one more muscle than had been thought, according to a study published Feb. 14, 2018 in the open-access journal PLOS ONE by Russell Bicknell from University of New England, Australia, and colleagues.
It turns out that nobody knows when rabbits were domesticated. Despite a well-cited story of the domestic bunny's origins, a review published on Feb. 14 in Trends in Ecology and Evolution finds that historical and archaeological records and genetic methods all suggest different timeframes for its domestication. But the researchers involved in the study don't think this puzzle is a dead end. Instead, they believe it's an indication that domestication happens on a continuum.
Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn't do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. Cognitive biologists from Vetmeduni Vienna propose computer interaction as a practical alternative.
The lion population of Zimbabwe's Savé Valley Conservancy shows low genetic diversity despite improved numbers, according to a study published Feb. 7, 2018 in the open-access journal PLOS ONE by Laura Tensen from the University of Johannesburg, South Africa, and colleagues based in the Savé Valley Conservancy.
The drum rolls of great spotted woodpeckers may be used to identify individuals, according to a study published Feb. 7, 2018 in the open-access journal PLOS ONE by Michal Budka from Adam Mickiewicz University, Poland, and colleagues.
In a study using equine mesenchymal stem cells, Morris Animal Foundation-funded researchers from Cornell University and North Carolina State University found that stem cell function can be enhanced through manipulation of their culture environment, and that 'priming' prior to patient administration could optimize their therapeutic potential. The research team published their results in Veterinary Immunology and Immunopathology.
Public awareness campaigns on spotting the signs and symptoms of infectious diseases and how to prevent them, play a key role in helping to stop the spread of such infections, a new study in the journal Epidemiology and Infection reports.
While it is largely believed that horses simply evolved with fewer digits, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) pose a new theory that suggests remnants of all five toes are still present within the hooves of the horse.
