Frogs

When glassfrogs sleep, they turn their bodies transparent in order to evade predators. Scientists have now discovered that they do so by moving their red blood cells into their liver – and the finding could have implications for human medicine.

Evolution occurs as species adapt to environmental pressures, and few environments exert pressures like the Chernobyl exclusion zone. A new study shows evolution in action as frogs within the radioactive region are turning blacker than those outside.

Chronic skin ulcers are notoriously slow to heal, but an otherwise-wasted material may soon help change that. Scientists at Singapore's Nanyang Technological University have developed a new regenerative wound dressing, and it's made from frog skin.

Animals like axolotls can regrow fully functional replacements for lost limbs. In a breakthrough new study, scientists have demonstrated how one dose of a drug cocktail can regrow lost limbs in frogs that don’t normally have regenerative abilities.

Scientists have developed first-of-a-kind "Xenobots" from frog cells with the ability to self-replicate, a technology that could find use in regenerative medicine and and reveals a type of biological reproduction never before observed in science.

The people of Singapore consume a lot of fish, and – perhaps surprisingly to some of us – a lot of frog meat. Scientists have now developed a method of converting the waste from both foods into a material that helps bone to regrow.

A number of hearing aids are now able to amplify one person's voice while filtering out distracting background voices. Well, it turns out that female tree frogs are able to perform a similar task, in order to hear the mating calls of males.

It can be hard to determine if an animal is extinct or just really good at hiding. A new study shows how environmental DNA can help the hunt, with several missing frog species rediscovered in Brazil, including one that hasn’t been seen in 50 years.

The line between robots and living organisms is beginning to blur. Researchers at the University of Vermont and Tufts University have now essentially created new creatures from frog cells, complete with programmable behaviors.

Frog populations are a key indicator of an area's ecological health, and one of the best ways of gauging their levels involves estimating the number of frog vocalizations being made at one time. The FrogPhone could make it easier than ever to do so.

​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.
