The process was discovered following an infection of one patient, who had to undergo four amputations during a life-saving procedure after the disease turned deadly.

The last documented individual was killed by a hunter in 1990.

Researchers say their findings represent some of the first evidence that evolutionary changes are affecting the time of year that wild animals give birth.

The Parc Zoologique de Paris, in France, launched a special exhibit in October bidding visitors to "come meet a fascinating creature, neither plant nor animal nor fungus: the blob."

"I chose this name as I am immensely impressed with the work of this young campaigner," the scientist behind the naming said.

Batesian mimicry is where a harmless species avoids predators by pretending to be a dangerous or toxic one.

The findings could provide the foundation for new approaches to repair joint tissues and possibly even entire human limbs.

The creatures are invisible to the naked eye, measuring around 100 micrometers long—about as thick as a human hair.

Tardigrades—otherwise known as "water bears" or "moss piglets"—are considered extremophiles, organisms that thrive in extreme environments.

The new species is unique to New Guinea—the world's second-largest island.

The dinosaur could bite with about three times the force of large crocodiles or great white sharks.

"it's never been proven," said Brainerd School District chair Sue Kern. "So I'm wondering why we're still teaching it."

Chinese giant salamanders were once common across a huge area of China, however, the animals have suffered dramatic declines in recent times

Short-faced kangaroos are an entirely extinct group of marsupial herbivores that arose during the Miocene Epoch—around 23 to 5.3 million years ago—and diversified prolifically during Australia's Ice Age.

This type of mating behavior, where a generation of males die off in their first season, is very rare in the animal kingdom.

Even in the starkest of situations, the act of eating another human's flesh remains almost beyond contemplation.

Leeches are parasitic worms that feed on the blood of animals.

The invasion of insects in the state follows similar events in Las Vegas, Nevada and southern Idaho over recent weeks.

The researchers utilized special electric signals generated by eye movements to control and change the focal length of the soft lens.

The kauri tree—that should not be alive—could be part of a forest "superorganism," scientists say.

There are around 50 snake species in Russia, of which around 11 can pose a danger to humans.

The fungus (Ophiocordyceps unilateralis sensu lato) causes the death of its host before scattering its pores to infect other ants.

Chlamydia in koalas can lead to blindness, infertility and death. The disease is an important factor in the population declines that the species is experiencing.

It has long been thought that the first animals evolved from single-celled organisms resembling microbes called choanoflagellates that are found in water today.

The unusual creature has an extra eye socket in its skull.

The tiny critters could perch on your thumbnail.

Scientists discovered the hidden fluorescence by accident.

And for some of them, sex lasts 40 to 70 hours.

Some elephant bird species grew to heights of around 10 feet tall and could weigh up to 1,800 pounds.

Birds have a highly efficient respiratory system which enables them to sustain powered flight.
