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.

In fact, only about 25 percent of dogs vomited after eating grass.

So what’s the difference? Why can’t humans digest grass, if cows, goats and sheep can?
A study at the University of Queensland has revealed that birds always veer right while approaching head-on to avoid crashing into each other. Researchers believe their findings may have enormous potential in designing automated anti-crash systems on aircraft and autonomous drones.
