The world's first fluorescent frog, which glows bright green under UV light, has been discovered in Argentina. In normal light, the frog appears to have a muted palette of green/yellow skin with red dots, but under ultraviolet light, it glows a bright fluorescent green.
Scientists at Harvard are working on to resurrect the woolly mammoth from extinction through an ambitious feat of genetic engineering. According to the scientist leading the 'de-extinction' effort, the team could be just two years away from creating a hybrid elephant-mammoth embryo, in which the genes extracted from the frozen remains of woolly mammoth would be spliced into the DNA of an Asian elephant.
Wild vampire bats, that were previously only thought to feed on the blood of birds, have been caught feeding on humans for the first time. Analysis of feces samples from 70 of hairy-legged vampire bats, D. ecaudata, living in Catimbau National Park in north-east Brazil showed three samples out of the 15 the researchers managed to get DNA from had traces of human blood.
Egyptian fruit bats make noises in their colonies to actually communicate with one another. Most bats make loud random noises when they congregate in their colonies. But until now, researchers hadn't known whether their calls served a specific purpose or they were simply making random noises.
Tail of feathered dinosaur that lived 99 million years ago have been found preserved in an ancient blob of amber tree resin. CT scans and microscopic analysis revealed it belonged to a small, flightless dinosaur.
Dogs eat grass as the natural remedy to make themselves vomit. The idea here is that they might start eating grass when they don't feel well or there's something else going on in their digestive system. But in a study that looked into this matter, only 8 percent of grass eating dogs were ill prior to eating grass, and grass eating usually doesn't lead to vomiting. In fact, only about 25 percent of dogs vomited after eating grass.
Cats sleep for 18 to 20 hours a day. Considering this, they don’t really seem like the kind of mammal that can experience anxiety. But, what’s true is that they do experience anxiety like any other mammal, and sitting inside the box helps them cope with it.
Scientists have discovered that Tasmanian devil milk contains antimicrobial peptides that can kill some of the world’s deadliest bacterial and fungal infections known to science, including golden staph.
You have probably seen cows contently enjoying a nice mouthful of grass. Basically, there are grasses everywhere you go; and although it’s a well-known fact that that humans can live well and thrive on a totally vegetarian diet, eating grass unfortunately wouldn’t do much for us. So what’s the difference? Why can’t humans digest grass, if cows, goats and sheep can?
