A new study casts doubt over the validity of models used to assess the impact of radiation on human health.
Moths are iconic examples of camouflage. Their wing coloration and patterns are shaped by natural selection to match the patterns of natural substrates, such as a tree bark or leaves, on which the moths rest. But, according to recent findings, the match in the appearance was not all in their invisibility.

The population of Australia's feral camel has dropped by a quarter, but still remains the world's largest wild herd, according to a survey by the Australian Feral Camel Management Project (AFCMP).
At least 79 new species of sharks have been discovered by the scientists in South Carolina. Researchers at the Hollings Marine Laboratory at Fort Johnson on Charleston Harbor studied the DNA by allowing the genes to stick to the molecules. This way the researchers were able to compare the genetic coding of the 79 new species with that of the other species. They found that the newly discovered sharks are different from others and called them the "cryptic" species.
It is well known that animals moving in groups try to force themselves to the center of the group when they sense a predator attack. For the first time researchers have proven this theory using Global Positioning System (GPS).
A team of researchers have created an artificial jellyfish using rat heart muscle tissue and thin silicon polymer to study the human heart and its circulatory system.
