Frogs

  • ​If you're a fan of frogs, then unfortunately you've probably heard of ​​Batrachochytrium dendrobatidis​​ (Bd). It's been decimating amphibian populations around the world. Now, however, scientists believe they know where it originates – and that knowledge could help keep it from spreading.
  • ​Batrachochytrium dendrobatidis (Bd) is a deadly skin fungus that threatens populations of frogs and salamanders around the world. There may be new hope for catching it early enough to limit amphibian fatalities, however, thanks to the analysis of what's known as environmental DNA.
  • ​How is it that some frogs are able to flush toxins through their bodies that poison would-be predators without causing any harm to themselves? Scientists have pinpointed the mechanism that enables some types of frog to dodge the danger.
  • The beach ball-sized Beelzebufo (devil toad) lived 68 million years ago, and a new study suggests it may have dined on dinosaurs. By measuring the bite force of its living relatives, researchers were able to scale up their findings to estimate the jaw strength of the extinct big-mouthed behemoths.
  • ​​So-called "glassfrogs" are known as such because the skin on their bellies is transparent, leaving their lower abdominal organs visible. In a newly-discovered species of glassfrog from Amazonian Ecuador, however, that transparency extends to the animal's chest.
  • Frog mucus might seem like the kind of flu remedy a witch doctor would suggest, but researchers have found that certain peptides excreted by frogs can fight off human flu strains. As such, they could be used as emergency stand-ins during flu outbreaks when regular vaccines aren’t available.
  • Science
    Researchers at Georgia Tech have discovered that frog saliva switches between watery and viscous states, allowing the animals to both catch prey and then whip it back into their mouths. The findings could have implications for human technology.​
  • Frogs are increasingly having more sex on dry land than in rivers and lakes and new research says that the reason for this might be for males to avoid competition from other males. In arriving at this theory, the researchers took a look at frog testes.
  • When the Tungara frog lays its eggs, it also produces a foam. Surrounding the eggs, that foam protects them. As it turns out, a synthetic version of the substance may also one day have another use – delivering medication to serious skin wounds.
  • Science
    Scientists working on the “de-extinction” Lazarus Project have successfully revived and reactivated the genome of an extinct Australian frog called the gastric-brooding frog.
  • Science
    Researchers have discovered that a substance from frog skin could replace the crab blood currently used for detecting bacteria on drugs and medical devices.
  • Frog skin could thwart antibiotic-resistant germs.
